RESUMEN

OBJECTIVE: To investigate technical success and safety of percutaneous patent ductus arteriosus closure in infants ≤1.5 kg. STUDY DESIGN: A systematic review and meta-analysis was performed. Data sources included Scopus, Web of Science, Embase, CINAHL, Cochrane, and PubMed from inception to April 2020. Publications were included if they had a clear definition of the intervention as percutaneous patent ductus arteriosus closure in infants ≤1.5 kg. Data extraction was independently performed by multiple observers. Primary outcome was technical success and secondary outcomes were adverse events (AEs). Subgroup analysis was performed in infants ≤6.0 kg. Data were pooled by using a random-effects model. RESULTS: We included 28 studies, including 373 infants ≤1.5 kg and 69 studies enrolling 1794 infants ≤6.0 kg. In patients ≤1.5 kg, technical success was 96% (95% CI, 93%-98%; P = .16; I2 = 23%). The overall incidence of AE was 27% (95% CI, 17%-38%; P < .001; I2 = 70%) and major AEs was 8% (95% CI, 5%-10%; P = .63; I2 = 0%). There were 5 deaths related to the procedure (2%; 95% CI, 1%-4%; P = .99; I2 = 0%); 4 of these deaths occurred in infants <0.8 kg. The probability of technical failure was inversely related to age at the time of the procedure (OR, 0.9; 95% CI, 0.830-0.974; P = .009). Weight at intervention has decreased over time and procedural success has increased. CONCLUSIONS: Percutaneous patent ductus arteriosus closure is feasible in infants ≤1.5 kg with few major AEs. The procedural success rate is high, despite performing the intervention in smaller patients. PROSPERO REGISTRATION: CRD42020145230.

RESUMEN

BACKGROUND: Cardiac catheterization is the gold standard for assessment and follow-up of patients with pulmonary hypertension (PH). To date, there are limited data about the factors that influence the risk of catastrophic adverse events after catheterization in this population. METHODS AND RESULTS: A retrospective multicenter cohort study was performed to measure risk of catastrophic adverse outcomes after catheterization in children and young adults with PH and identify risk factors for these outcomes. All catheterizations in children and young adults, aged 0 to 21 years, with PH at hospitals submitting data to the IMPACT (Improving Adult and Congenital Treatment) registry between January 1, 2011, and December 31, 2015, were studied. Using mixed-effects multivariable regression, we assessed the association between prespecified subject-, procedure-, and center-level covariates and the risk of death, cardiac arrest, or mechanical circulatory support during or after cardiac catheterization. A total of 8111 procedures performed in 7729 subjects at 77 centers were studied. The observed risk of the composite outcome was 1.4%, and the risk of death before discharge was 5.2%. Catheterization in prematurely born neonates and nonpremature infants was associated with increased risk of catastrophic adverse event, as was precatheterization treatment with inotropes and lower systemic arterial saturation. Secondary analyses demonstrated the following: (1) increasing volumes of catheterization in patients with PH were associated with reduced risk of composite outcome (odds ratio, 0.8 per 10 procedures; P=0.002) and (2) increasing pulmonary vascular resistance and pulmonary artery pressures were associated with increased risk (P<0.0001 for both). CONCLUSIONS: Young patients with PH are a high-risk population for diagnostic and interventional cardiac catheterization. Hospital experience with PH is associated with reduced risk, independent of total catheterization case volume.

RESUMEN

BACKGROUND: Current guidelines recommend early P2Y12 inhibitor administration in non-ST-elevation myocardial infarction, but it is unclear if precatheterization use is associated with longer delays to coronary artery bypass grafting (CABG) or higher risk of post-CABG bleeding and transfusion. This study examines the patterns and outcomes of precatheterization P2Y12 inhibitor use in non-ST-elevation myocardial infarction patients who undergo CABG. METHODS AND RESULTS: Retrospective analysis was done of 20 304 non-ST-elevation myocardial infarction patients in the ACTION (Acute Coronary Treatment and Intervention Outcomes Network) Registry (2009-2014) who underwent catheterization within 24 hours of admission and CABG during the index hospitalization. Using inverse probability-weighted propensity adjustment, we compared time from catheterization to CABG, post-CABG bleeding, and transfusion rates between patients who did and did not receive precatheterization P2Y12 inhibitors. Among study patients, 32.9% received a precatheterization P2Y12 inhibitor (of these, 2.2% were given ticagrelor and 3.7% prasugrel). Time from catheterization to CABG was longer among patients who received precatheterization P2Y12 inhibitor (median 69.9 hours [25th, 75th percentiles 28.2, 115.8] versus 43.5 hours [21.0, 71.8], P<0.0001), longer for patients treated with prasugrel (median 114.4 hours [66.5, 155.5]) or ticagrelor (90.4 hours [48.7, 124.5]) compared with clopidogrel (69.3 [27.5, 114.6], P<0.0001). Precatheterization P2Y12 inhibitor use was associated with a higher risk of post-CABG major bleeding (75.7% versus 73.4%, adjusted odds ratio 1.33, 95% confidence interval 1.22-1.45, P<0.0001) and transfusion (47.6% versus 35.7%, adjusted odds ratio 1.51, 95% confidence interval 1.41-1.62, P<0001); these relationships did not differ among patients treated with clopidogrel, prasugrel, or ticagrelor. CONCLUSIONS: Precatheterization P2Y12 inhibitor use occurs commonly among non-ST-elevation myocardial infarction patients who undergo early catheterization and in-hospital CABG. Despite longer delays to surgery, the majority of pretreated patients proceed to CABG <3 days postcatheterization. Precatheterization P2Y12 inhibitor use is associated with higher risks of postoperative bleeding and transfusion.

RESUMEN

INTRODUCTION:: Although it only corresponds to 2.5% of congenital heart defects, hypoplastic left heart syndrome (HLHS) is responsible for more than 25% of cardiac deaths in the first week of life. Palliative surgery performed after the second week of life is considered an important risk factor in the treatment of HLHS. OBJECTIVE:: The aim of this study is to describe the initial experience of a medical center in Northeastern Brazil with a modified off-pump hybrid approach for palliation of HLHS. METHODS:: From November 2012 through November 2015, the medical records of 8 patients with HLHS undergoing hybrid procedure were retrospectively evaluated in a tertiary private hospital in Northeastern Brazil. The modified off-pump hybrid palliation consisted of stenting of the ductus arteriosus guided by fluoroscopy without contrast and banding of the main pulmonary artery branches. Demographic and clinical variables were recorded for descriptive analysis. RESULTS:: Eight patients were included in this study, of whom 37.5% were female. The median age and weight at the time of the procedure was 2 days (p25% and p75% = 2 and 4.5 days, respectively) and 3150 g (p25% and p75% = 3077.5 g and 3400 g, respectively), respectively. The median length in intensive care unit stay was 6 days (p25% and p75% = 3.5% and 8 days, respectively). There were no in-hospital deaths. Four patients have undergone to the second stage of the surgical treatment of HLHS. CONCLUSION:: In this series, the initial experience with the modified off-pump hybrid procedure showed to be safe, allowing a low early mortality rate among children presenting HLHS.

RESUMEN

OBJECTIVES: This study aimed to compare gender-related differences in outcomes of patients undergoing TAVI over a long-term follow-up period. BACKGROUND: Transcatheter aortic valve implantation (TAVI) has been considered the standard therapy for patients with inoperable or high-risk symptomatic aortic stenosis. The influence of gender-related differences in outcomes of patients undergoing TAVI is currently on debate. METHODS: From January 2008 to January 2015, 819 patients (49% men) underwent TAVI and were included in a multicenter Brazilian registry. Patients were followed-up and clinical outcomes were evaluated according to the updated Valve Academic Research Consortium-2 criteria. RESULTS: Mean follow-up was 497 ± 478 days. Compared with women, men had a lower rate of major or life-threatening bleeding (12.0% vs. 20.6%; HR = 0.57 [95CI% 0.40-0.81]; P = 0.001), and major vascular complications (6% vs. 11.7%; HR = 0.50 [95CI% 0.31-0.82]; P = 0.004). At 30 days, all-cause mortality was lower in men than in women (6.5% vs. 11.5%; P = 0.013), however, cumulative all-cause mortality was similar between groups (25.9% vs. 29.7%, men and women, respectively, HR = 0.92 [95CI% 0.71-1.19]; P = 0.52) over the entire follow-up period. By adjusted Cox regression model, renal function, diabetes, peripheral artery disease, and chronic obstructive pulmonary disease (COPD) remained independently predictors of all-cause mortality. CONCLUSIONS: In this large-scale study evaluating patients undergoing TAVI, 30-day mortality was higher among women than men driven by significant higher rates of major or life-threatening bleeding and major vascular complications. However, all-cause mortality on long-term follow-up was similar between groups. © 2016 Wiley Periodicals, Inc.

RESUMEN

OBJECTIVES: This study sought to evaluate the outcomes of the early experience of transcatheter mitral valve replacement (TMVR) with balloon-expandable valves in patients with severe mitral annular calcification (MAC) and reports the first large series from a multicenter global registry. BACKGROUND: The risk of surgical mitral valve replacement in patients with severe MAC is high. There are isolated reports of successful TMVR with balloon-expandable valves in this patient population. METHODS: We performed a multicenter retrospective review of clinical outcomes of patients with severe MAC undergoing TMVR. RESULTS: From September 2012 to July of 2015, 64 patients in 32 centers underwent TMVR with compassionate use of balloon-expandable valves. Mean age was 73 ± 13 years, 66% were female, and mean Society of Thoracic Surgeons score was 14.4 ± 9.5%. The mean mitral gradient was 11.45 ± 4.4 mm Hg and the mean mitral area was 1.18 ± 0.5 cm(2). SAPIEN valves (Edwards Lifesciences, Irvine, California) were used in 7.8%, SAPIEN XT in 59.4%, SAPIEN 3 in 28.1%, and Inovare (Braile Biomedica, Brazil) in 4.7%. Access was transatrial in 15.6%, transapical in 43.8%, and transseptal in 40.6%. Technical success according to Mitral Valve Academic Research Consortium criteria was achieved in 46 (72%) patients, primarily limited by the need for a second valve in 11 (17.2%). Six (9.3%) had left ventricular tract obstruction with hemodynamic compromise. Mean mitral gradient post-procedure was 4 ± 2.2 mm Hg, paravalvular regurgitation was mild or absent in all. Thirty-day all-cause mortality was 29.7% (cardiovascular = 12.5% and noncardiac = 17.2%); 84% of the survivors with follow-up data available were in New York Heart Association functional class I or II at 30 days (n = 25). CONCLUSIONS: TMVR with balloon-expandable valves in patients with severe MAC is feasible but may be associated with significant adverse events. This strategy might be an alternative for selected high-risk patients with limited treatment options.

RESUMEN

AIMS: We sought to examine the feasibility and reproducibility of a new video densitometric (VD) quantification of aortic regurgitation (AR) on aortography, and its long-term clinical impact. METHODS AND RESULTS: Using dedicated video densitometry software, AR after TAVI was quantified, and inter- and intra-observer reproducibility was investigated in 182 aortograms of the Brazilian TAVI registry. The aortograms were analysed using two software algorithms: 1) the quantitative regurgitation analysis (qRA) index interrogating the entire left ventricle (LV), and 2) a new method with the left ventricle outflow tract (LVOT) as a region of interest (ROI) (LVOT-AR). LVOT-AR was feasible in 64.8% vs. 29.7% of aortograms, compared with qRA index. Using the LVOT-AR, inter-observer variability was low (mean difference±standard deviation [SD]: 0.01±0.05, p=0.53), and the two observers' measurements were highly correlated (r=0.95, p<0.001). Patients with LVOT-AR >0.17 had a significantly higher one-year all-cause mortality risk compared with patients with LVOT-AR ≤0.17 (37.1% vs. 11.2%, p=0.0008). CONCLUSIONS: This study proposes an alternative methodology for AR assessment after TAVI by using the LVOT method (LVOT-AR) of VD angiography. The assessment of LVOT-AR is feasible, reproducible and potentially predictive of one-year mortality.

RESUMEN

AIMS: Transcatheter aortic valve implantation has emerged as an alternative to conventional aortic valve replacement in high-risk patients. Diverse prostheses are currently under investigation. The aim of this study was the clinical, safety and efficacy assessment of Braile Inovare Transcatheter Aortic Prosthesis usage. METHODS AND RESULTS: Ninety high-risk or inoperable patients underwent transcatheter aortic valve implantation. The mean logistic EuroSCORE was 39.3%. All patients presented calcified aortic stenosis. The procedures were performed under fluoroscopic and echocardiographic guidance. Prostheses were implanted through the transapical approach under rapid ventricular pacing. Echocardiographic and angiographic controls were included. Implantation was feasible in 87 cases. There was only one case of operative mortality, and 30-day mortality was 13.3%. The median transvalvular aortic gradient was reduced from 44.8±15.3 to 14.1±8.0 mmHg. Left ventricular function improved in the first seven postoperative days. Paravalvular aortic regurgitation was present in 29.7% of cases, mostly trace. One case presented a major vascular complication, and there were two cases of permanent pacemaker implantation. Two cases of major stroke occurred. CONCLUSIONS: Transcatheter aortic valve replacement using the Braile Inovare prosthesis is able to provide encouraging results with significant functional and structural cardiac improvement. It is mandatory to continue follow-up to measure the benefits of this device as well as to improve selection criteria of patients.

RESUMEN

AIMS: This study aimed to evaluate the safety and performance of the TriGuard™ Embolic Deflection Device (EDD), a nitinol mesh filter positioned in the aortic arch across all three major cerebral artery take-offs to deflect emboli away from the cerebral circulation, in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: The prospective, multicentre DEFLECT I study (NCT01448421) enrolled 37 consecutive subjects undergoing TAVR with the TriGuard EDD. Subjects underwent clinical and cognitive follow-up to 30 days; cerebral diffusion-weighted magnetic resonance imaging (DW-MRI) was performed pre-procedure and at 4±2 days post procedure. The device performed as intended with successful cerebral coverage in 80% (28/35) of cases. The primary safety endpoint (in-hospital EDD device- or EDD procedure-related cardiovascular mortality, major stroke disability, life-threatening bleeding, distal embolisation, major vascular complications, or need for acute cardiac surgery) occurred in 8.1% of subjects (VARC-defined two life-threatening bleeds and one vascular complication). The presence of new cerebral ischaemic lesions on post-procedure DW-MRI (n=28) was similar to historical controls (82% vs. 76%, p=NS). However, an exploratory analysis found that per-patient total lesion volume was 34% lower than reported historical data (0.2 vs. 0.3 cm3), and 89% lower in patients with complete (n=17) versus incomplete (n=10) cerebral vessel coverage (0.05 vs. 0.45 cm3, p=0.016). CONCLUSIONS: Use of the first-generation TriGuard EDD during TAVR is safe, and device performance was successful in 80% of cases during the highest embolic-risk portions of the TAVR procedure. The potential of the TriGuard EDD to reduce total cerebral ischaemic burden merits further randomised investigation.

RESUMEN

BACKGROUND: Transcatheter aortic valve implantation is an effective alternative to surgical treatment of severe aortic stenosis in patients who are inoperable or at high surgical risk. OBJECTIVES: To report the immediate and follow-up clinical and echocardiographic results of the initial experience of transcatheter aortic valve implantation. METHODS: From 2009 June to 2013 February, 112 patients underwent transcatheter aortic valve implantation. RESULTS: Mean age was 82.5 ± 6.5 years, and the logistic EuroSCORE was 23.6 ± 13.5. Procedural success was 84%. After the intervention, a reduction in the mean systolic gradient was observed (pre: 54.7 ± 15.3 vs. post: 11.7 ± 4.0 mmHg; p < 0.01). Cerebrovascular accidents occurred in 3.6%, vascular complications in 19% and permanent pacemaker was required by 13% of the patients. Thirty-day mortality and at follow-up of 16 ± 11 months was 14% and 8.9% respectively. The presence of chronic obstructive pulmonary disease was the only predictor of mortality at 30 days and at follow-up. During follow up, aortic valve area and mean systolic gradient did not change significantly. CONCLUSIONS: Transcatheter aortic valve implantation is an effective and safe procedure for the treatment of aortic stenosis in high-surgical risk or inoperable patients. The presence of chronic obstructive pulmonary disease was the only independent predictor of mortality identified both in the first month post-intervention and at follow-up.

RESUMEN

Fundamento: O implante de prótese aórtica transcateter é uma alternativa efetiva para o tratamento cirúrgico para a correção de estenose aórtica grave em pacientes inoperáveis ou de alto risco cirúrgico. Objetivos: Apresentar os resultados clínicos e ecocardiográficos imediatos e no médio prazo da experiência inicial do implante de prótese aórtica transcateter. Métodos: Entre junho de 2009 e fevereiro de 2013, 112 pacientes foram submetidos a implante de prótese aórtica transcateter. Resultados: A idade média foi 82,5 ± 6,5 anos e o Euro SCORE logístico foi 23,6 ± 13,5. O sucesso do procedimento foi de 84%. Após o implante, houve queda do gradiente sistólico médio (pré = 54,7 ± 15,3 mmHg vs. pós = 11,7 ± 4,0 mmHg; p < 0,01). Acidente vascular cerebral ocorreu em 3,6% dos pacientes, complicações vasculares em 19%, e foi necessário o implante de marca-passo definitivo em 13% dos pacientes nos primeiros 30 dias pós-implante. A mortalidade aos 30 dias e no seguimento médio de 16 ± 11 meses foi, respectivamente, de 14 e de 8,9%. A presença de doença pulmonar obstrutiva crônica foi o único preditor de mortalidade em 30 dias e no seguimento. A área valvar aórtica e o gradiente sistólico médio não apresentaram variações significativas durante o seguimento. Conclusões: O implante de prótese aórtica transcateter é um procedimento eficaz e seguro para o tratamento da estenose aórtica em pacientes de alto risco cirúrgico ou inoperáveis. A presença de doença pulmonar obstrutiva crônica foi o único preditor independente de mortalidade identificado, tanto no primeiro mês pós-intervenção quanto no seguimento mais tardio. .

RESUMEN

AIM: To assess the results of transcatheter aortic valve implantation (TAVI) using the Medtronic CoreValve prosthesis (Medtronic, Minneapolis, MN), without balloon predilation, in high-risk patients with degenerated severe aortic stenosis. METHODS AND RESULTS: Fifty-one consecutive patients who underwent direct TAVI, 98% through a transfemoral approach. Patients were 79 ± 8 years of age, 74% in New York Heart Association classes III or IV and at high risk for surgical valve replacement (mean logistic EuroScore 20 ± 15). Mean aortic valve area was 0.7 ± 0.2 cm(2). Procedural success rate was 94.2%. In-hospital, there were 2 deaths, 1 minor stroke with minimal sequelae, and 14 (28%) pacemaker implantation. At 30 days, there was one additional stroke and no new deaths. The mean postprocedural transprosthetic gradient was 15 ± 5 mm Hg; periprosthetic severe regurgitation was absent and moderate in one case. After a median follow-up of 7 months, there were five additional deaths (two cardiac), while 84% of survivors were in New York Heart Association classes I or II. CONCLUSIONS: These results suggest that direct CoreValve implantation in patients with severe aortic stenosis is feasible and may lead to hemodynamic and clinical improvement in patients who are poor candidates for aortic valve surgery, pending confirmation in larger series with longer follow-up.

RESUMEN

BACKGROUND: Blood transfusion is associated with acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI). We sought to elucidate in more detail the relation between blood transfusion and AKI and its effects on short- and long-term mortality. METHODS AND RESULTS: Nine hundred ninety-five patients with aortic stenosis underwent TAVI with the Medtronic CoreValve or the Edwards Valve in 7 centers. AKI was defined by the Valve Academic Research Consortium (absolute increase in serum creatinine ≥0.3 mg/dL [≥26.4 µmol/L] or ≥50% increase ≤72 hours). Logistic and Cox regression was used for predictor and survival analysis. AKI occurred in 20.7% (n=206). The number of units of blood transfusion ≤24 hours was the strongest predictor of AKI (≥5 units, OR, 4.81 [1.45-15.95], 3-4 units, OR, 3.05 [1.24-7.53], 1-2 units, OR, 1.47 [0.98-2.22]) followed by peripheral vascular disease (OR, 1.48 [1.05-2.10]), history of heart failure (OR, 1.43 [1.01-2.03]), leucocyte count ≤72 hours after TAVI (OR, 1.05 [1.02-1.09]) and European System for Cardiac Operative Risk Evaluation (EuroSCORE; OR, 1.02 [1.00-1.03]). Potential triggers of blood transfusion such as baseline anemia, bleeding-vascular complications, and perioperative blood loss were not identified as predictors. AKI and life-threatening bleeding were independent predictors of 30-day mortality (OR, 3.15 [1.56-6.38], OR, 6.65 [2.28-19.44], respectively), whereas transfusion (≥3 units), baseline anemia, and AKI predicted mortality beyond 30 days. CONCLUSIONS: AKI occurred in 21% of the patients after TAVI. The number of blood transfusions but not the indication of transfusion predicted AKI. AKI was a predictor of both short- and long-term mortality, whereas blood transfusion predicted long-term mortality. These findings indicate that outcome of TAVI may be improved by more restrictive use of blood transfusions.

RESUMEN

INTRODUÇÃO: A reoperação para substituição de biopróteses aórticas com disfunção é procedimento que envolve considerável risco. Em alguns casos, a mortalidade é elevada e pode contraindicar o procedimento. O implante minimamente invasivo "valve-in-valve" transcateter de valva aórtica parece ser uma alternativa, reduzindo morbimortalidade. O objetivo deste estudo foi avaliar esses implantes utilizando a prótese Braile Inovare. MÉTODOS: A prótese Braile Inovare, transcateter, balão expansível foi utilizada em 14 casos. Euroscore médio foi de 42,9%. Todos os pacientes eram portadores de dupla disfunção de bioprótese aórtica. Os procedimentos foram realizados em ambiente cirúrgico híbrido, sob controle ecocardiográfico e fluoroscópico. Por meio de minitoracotomia esquerda, as próteses foram implantadas através do ápice ventricular, sob estimulação ventricular de alta frequência. Foram realizados controles clínicos e ecocardiográficos seriados. O seguimento variou de 1 a 30 meses. RESULTADOS: A correta liberação protética foi possível em todos os casos. Não ocorreu conversão. Não houve mortalidade operatória. A mortalidade em 30 dias foi de 14,3% (dois casos). A fração de ejeção apresentou aumento significativo após o 7º pós-operatório e o gradiente aórtico apresentou redução significativa. A insuficiência aórtica residual não esteve presente. Não ocorreu complicação vascular periférica ou bloqueio atrioventricular total. CONCLUSÕES: O implante "valve-in-valve" de valva aórtica transcateter em biopróteses com disfunção é um procedimento seguro e com morbimortalidade baixa. Essa possibilidade poderá alterar a indicação de seleção de prótese no procedimento inicial, favorecendo próteses biológicas.


OBJECTIVE: Aortic valve replacement for bioprosthesis dysfunction is a procedure involving considerable risk. In some cases, mortality is high and may contraindicate the procedure. Minimally invasive transcatheter aortic "valve-in-valve" implant appears to be an alternative, reducing morbidity and mortality. The objective is to evaluate aortic valve-in-valve procedure using Braile Inovare prosthesis. METHODS: The Braile Inovare prosthesis, transcatheter, expandable balloon, was used in 14 cases. Average EuroSCORE was 42.9%. All patients had double aortic bioprosthesis dysfunction. Procedures were performed in a surgical hybrid environment under echocardiographic and fluoroscopic guidance. Using left minithoracotomy prostheses were implanted through the ventricular apex under high-frequency ventricular pacing. Serial clinical and echocardiographic controls were performed. Follow-up ranged 1-30 months. RESULTS: Correct prosthetic deployment was obtained in all cases. There was no conversion. There was no operative mortality. The 30-day mortality was 14.3% (two cases). Ejection fraction increased significantly after the 7th postoperative day. Aortic gradient significantly reduced. The residual aortic regurgitation was not present. There were no vascular complications or complete atrioventricular block. CONCLUSION: The transcatheter "valve-in-valve" procedure for bioprosthesis dysfunction is safe with low morbidity. This possibility may change prosthesis choice during the first aortic valve replacement, favoring bioprostheses.

RESUMEN

At our institutions, increasing numbers of aortic stenosis patients were not candidates for surgical aortic valve replacement. Accordingly, we initiated the Cali Colombian Transcatheter Aortic Valve Implantation (TAVI) program. From March 2008 through January 2011, 53 consecutive patients (mean age, 79 ± 6 yr; men, 58%) underwent TAVI with the Medtronic CoreValve System, and data were prospectively collected. Our study's endpoints conformed with Valve Academic Research Consortium recommendations. We report our clinical results.Predicted mortality rates were 25% (interquartile range, 17%-34%) according to logistic EuroSCORE and 6% (interquartile range, 3%-8%) according to the Society of Thoracic Surgeons score. The 30-day mortality rate was 9% (3 intraprocedural deaths, 5 total). The combined 30-day safety endpoint was 30% (major vascular sequelae, 23%; life-threatening bleeding, 12%; myocardial infarction, 4%; major stroke, 4%; and acute kidney injury [stage 3], 2%). Eight patients (15%) required post-implantation balloon dilation and 2 (4%) required valve-in-valve implantation, for a technical device success rate of 77%. Mean peak transvalvular gradient decreased from 74 ± 29 to 17 ± 8 mmHg and mean transvalvular gradient from 40 ± 17 to 8 ± 4 mmHg (both P=0.001). Moderate or severe aortic regurgitation decreased from 32% to 18% (P=0.12) and mitral regurgitation from 32% to 13% (P=0.002). The 1-year survival rate was 81%.We found that TAVI with the CoreValve prosthesis was safe and feasible, with sustained long-term results, for treating aortic stenosis in patients at excessive surgical risk; nonetheless, serious adverse events occurred in 30% of the patients.

RESUMEN

Introdução: As complicações relacionadas ao cateterismo cardíaco são os principais limitantes desta técnica, e podem variar desde eventos adversos leves e transitórios até eventos graves, como infarto do miocárdio ou morte. Objetivo: Avaliar a incidência de complicações imediatas do cateterismo cardíaco diagnóstico em adultos, conforme um modelo de categorização das complicações em tipo e gravidade. Método: Estudo de coorte prospectivo em um centro de referência. As características dos pacientes foram registradas, e estes foram acompanhados até a alta hospitalar. As complicações foram categorizadas em nove modalidades: alérgica, isquêmica, vascular, arrítmica, vaso-vagal, pirogênica, neurológica, embólica e congestivas, e estratificadas em leves (intercorrências), moderadas (resolvidas em até 24 horas) ou graves (necessitou internação ou intervenção). Os fatores preditivos de complicações foram identificados por análise multivariada. Resultados: Foram incluídos 1916 indivíduos, sendo 59,4% do sexo masculino e com média de idade de 58,3±11,1 anos. Complicações ocorreram em 175 pacientes (190 eventos), sendo que 62,5% foram intercorrências leves, 24% moderadas e 13,5% graves. Foi registrado apenas um óbito (0,05% dos indivíduos). As complicações vasculares foram as mais incidentes (35,6%), seguidas das vagais (18,3%), isquêmicas (15,4%) e alérgicas (14,4%). Os fatores de risco para complicações pela análise multivariada foram uso de anticoagulante (3,59; 1,67-7,74; p=0,006) e duração prolongada do exame (1,03; 1,02-1,04; p<0,001). Conclusão: As complicações relacionadas ao cateterismo cardíaco são geralmente intercorrências sem gravidade, sendo que as complicações vasculares, reações vagais e isquêmicas foram as mais freqüentes. O uso de anticoagulantes e o tempo de exame prolongado foram os principais fatores preditivos de complicações.


Background: The major limitations of cardiac catheterization are the occurrence of complications related to its invasive nature. Complications can vary from mild and transitory reactions to severe adverse events like myocardial infarction or death. Objective: To assess the incidence, type and severity of complications related to cardiac catheterization in adults using a comprehensive system previously described. Methods: We conducted a prospective cohort study in a tertiary reference center, and patient characteristics and in-hospital outcomes were registered in a dedicated database. Complications were categorized in nine types: allergic, ischemic, vascular, arrythmic, vagal, pyrogenic, neurological, embolic and congestive, and stratified in mild, moderate (resolved in 24 hours) or severe (needed hospitalization or another intervention). The predictive factors of complications were assessed by multivariate analysis. Results: We included 1916 individuals, 59% male and with a mean age of 58±11 years. Complications occurred in 175 patients (190 events), and 63% were mild, 24% moderate e 13% severe. There was one (0.05%) death in the entire cohort. Vascular complications were the most common type (36%), followed by vagal (18%), ischemic (15%) and allergic (14%). Risk factors for complications by multivariate analysis were anticoagulant use (OR=3.59; CI=1.67-7.74; p=0.006) and prolonged examination time (OR=1.03; CI=1.02-1.04; p<0.001). Conclusions: In-hospital complications after cardiac catheterization are generally mild, and the events more commonly presented were vascular, vagal or ischemic. Anticoagulant use and prolonged examination time were independent predictors of complications.

RESUMEN

Reportamos tres casos de endocarditis infecciosa tricuspidea secundaria al uso de marcapaso definitivo y la asociación de sépsis en cada uno de ellos. Un caso evolucionó satisfactoriamente con resolución del estado séptico pero con persistencia de la vegetación en la válvula tricuspidea. Los otros dos casos fallecieron posterior a falla de múltiples órganos. Uno de ellos con hemocultivo positivo para Estafilococo coagulasa positivo y otro para Estreptococo B-hemolitico, además de haber tenido infección del bolsillo del marcapaso por acinetobacter calcoacéticus y Citrobacter freundii. El ecocardiograma transesofágico fue de utilidad diagnóstica en dos de los casos además de permitir control de la evolución clínica

RESUMEN

This study evaluated three methods of catheter entry for cardiac catheterization in neonates less than one week of age. Eighty-five neonates underwent venous catheterization through the umbilical vein, 77 by saphenous or femoral cutdown, and 31 by femoral percutaneous entry. Of these 194 neonates, 128 also had an aortic catheter introduced via the umbilical artery. Umbilical vein catheterizations took an average of 115 minutes, 30 minutes shorter than either of the other techniques. Fatal complications following catheterization occurred in 10 of the 194 neonates (5%) three of these were related to catheterization technique. Diagnostic cardiac catheterization and balloon atrial septostomy may be performed most quickly by way of the umbilical vessels. Percutaneous entry of the femoral vein in this series carried the lowest complication rate; cutdown entry resulted in the highest complication rate.
