RESUMEN

BACKGROUND: In patients who underwent cardiac surgery, first-time postoperative atrial fibrillation (POAF) is associated with increased incidence of hospital-acquired complications and mortality. Systemic inflammation is one of confirmed triggers of its development. The anti-inflammatory properties of colchicine can be effective for the POAF prevention. However, the results of several studies were questionable and required further investigation. Hence, we aimed to evaluate the effectiveness of low-dose short-term colchicine administration for POAF prevention in patients after the open-heart surgery. This double-blind randomized placebo-controlled trial included 267 patients, but 27 of them dropped out in the course of the study. Study subjects received the test drug on the day before the surgery and on postoperative days 2, 3, 4 and 5. The rhythm control was conducted immediately after the operation and until the discharge from the hospital. The final analysis included 240 study subjects: 113 in the colchicine group and 127 in the placebo group. POAF was observed in 21 (18.6%) patients of the colchicine group vs. 39 (30.7%) control patients (OR 0.515; 95% Cl 0.281-0.943; p = 0.029). We observed no statistically significant differences between the patient groups in the secondary endpoints of the study (hospital mortality, respiratory failure, stroke, bleeding, etc.). For other parameters characterizing the severity of inflammation (pericardial effusion, pleural effusion, WBC count, neutrophil count), there were statistically significant differences between the groups in the early postoperative period (days 3 and 5). Also, statistically significant differences between the groups in the frequency of adverse events were revealed: the incidence of diarrhea in the colchicine group was 25.7% vs. 11.8% in the placebo group (OR 2.578; 95% Cl 1.300-5.111; p = 0.005); for abdominal pain, incidence values were 7% vs. 1.6%, correspondingly (OR 4.762; 95% Cl 1.010-22.91; p = 0.028). Thus, there were statistically significant differences between groups in the primary endpoint, thereby confirming the effectiveness of short-term colchicine use for the POAF prevention after coronary artery bypass grafting and/or aortic valve replacement. Also, we detected statistically significant differences between groups in the frequency of side effects to colchicine: diarrhea and abdominal pain were more common in the colchicine group. This clinical trial is registered with ClinicalTrials database under a unique identifier: NCT04224545.

RESUMEN

Objectives: To evaluate our 12-year experience with the Ross procedure in adults. Methods: A retrospective analysis of 215 cases of the Ross procedure was performed. The mean age of the patients was 36 ± 11.1 years, and the male to female ratio was 75% to 25%, respectively. The pulmonary autograft was placed into the aortic position using the full-root replacement technique and its modified versions. The right ventricular outflow tract was reconstructed using a pulmonary homograft in all cases. Results: The 30-day mortality after the operation was 0.9% (2 patients). The median duration of follow-up was 6.1 years (interquartile range, 6.5 years) and was complete in 86% of cases. The survival at 12 years was 94.7% and was comparable with the survival rate of the general population matched for age and sex. At the end of the follow-up, freedom from reoperation due to pulmonary autograft and homograft dysfunction was 89.1% and 99%, respectively. Conclusions: In our series, the Ross procedure resulted in low early mortality and excellent survival in adults. The long-term survival was not statistically different from the survival of the general population. The pulmonary homograft offered an excellent durability and freedom from reoperation.

RESUMEN

Kommerell's diverticulum (KD) is a rare congenital vascular abnormality due to the formation of an abnormal aortic arch, most commonly associated with dilatation at the proximal part of the aberrant subclavian artery. This article describes an option of surgical treatment in a patient with KD. The proposed new technique of aortic arch surgical reconstruction with a stent-graft placement in the descending aorta reduces CPB time, aortic clamp and circulatory arrest time.

RESUMEN

Abstract Introduction: The objective of this study was to identify risk factors for deep sternal wound infection (DSWI) after off-pump coronary artery bypass (OPCAB) grafting surgery. Methods: A total of 8,442 patients undergoing OPCAB from April 1, 2009 to December 31, 2018 were retrospectively analyzed. A total of 956 were eventually enrolled on this study based on our exclusion criteria. All subjects were divided into two groups: group 1 (n=63) - DSWI; group 2 (n=893) - without DSWI. Patients were excluded if they had one of the following: acute coronary syndrome, conversion to OPCAB grafting surgery, redo procedure, concomitant cardiac surgery procedures. Results: The prevalence of body mass index (BMI) ≥40 kg/m2 (7.9% vs. 1.9%, respectively; P=0.01), lower extremity atherosclerotic artery disease (23.8% vs. 7.2%, respectively; P=0.001) and use of bilateral internal thoracic artery (19.5% vs. 2.5%, respectively; P=0.008) was significantly higher in patients with DSWI. The incidence of morbidities, including reoperation for bleeding (26.4% vs. 2.1%, respectively; P<0.001), stroke (4.8% vs. 0.8%, respectively; P=0.02), acute renal failure (7.9% vs. 0.8%, respectively; P=0.001), delirium (7.9% vs. 1.7%, respectively; P=0.008) and blood transfusion (30.6% vs. 9.8%, respectively; P<0.001) was significantly higher in patients with DSWI. Conclusions: A BMI of >40 kg/m2, lower extremity artery disease, use of bilateral internal thoracic artery (BITA) graft, postoperative stroke, sepsis, reoperation due to postoperative complications and blood product requirement significantly increased the risk of sternal infection after OPCAB.

RESUMEN

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) techniques are increasingly being adopted into clinical routine for various risk groups. Coronary artery disease (CAD) is seen in up to 75% of patients with severe aortic valve stenosis (AS) presenting with typical angina pectoris. Due to high mortality rates and procedural complications in these patients, a hybrid concept of simultaneous transaortic TAVI and off-pump coronary artery bypass (OPCAB) can be a feasible treatment option. METHODS: Between April 2014 and July 2020, 10 consecutive high-risk patients underwent concomitant transaortic TAVI and OPCAB at our institution. All indications were discussed in Heart Team and decisions were made based on patients' comorbidities and complexity of CAD. The study endpoints were 30-day mortality, device success, and development of postoperative adverse events defined by the Valve Academic Research Consorium. RESULTS: The mean age of the patients was 77.9 ± 7.1 years old. All patients presented with multiple comorbidities (mean logistic EuroSCORE 26.5 ± 12.3%, median EuroSCORE II 5.13% [interquartile range 4.2-9.5], mean STS-Score 6.04 ± 1.6%). Five patients (50%) presented with porcelain aorta. No conversion to conventional procedures was needed. 30-day mortality occurred in one patient (10%). Complete revascularization was achieved in seven (70%) of the patients. Device success rate was 100%. No paravalvular leakage was detected. No stroke, myocardial infarction or vascular complications were observed. CONCLUSIONS: A hybrid approach combining transaortic TAVI and OPCAB might be a safe and feasible method of treatment in high-risk patients presenting with severe AS and CAD who are not eligible for conventional surgical or interventional solutions.

RESUMEN

BACKGROUND: Aortic root and ascending aortic aneurysms are traditionally surgically treated through the deployment of a conduit with an artificial aortic valve, which significantly increases the risk of postoperative complications in the form of thrombosis. MATERIALS & METHODS: We report a case of Wolfe procedure in a 78-year-old female patient with aortic root aneurysm at high risk for conventional Bentall surgery. DISCUSSION AND CONCLUSION: We use this case to discuss the effectiveness and short-term results of this procedure.

RESUMEN

BACKGROUND: The aim of the study was to compare results off-pump coronary artery bypass (OPCAB) combined mitral valve reconstruction (MVR) with standard on-pump approach. METHODS: From January 2014 to December 2017, a total of 53 patients received a combined myocardial revascularization and MVR for multivessel coronary artery disease (CAD) complicated by severe ischemic mitral regurgitation (IMR). All the subjects were divided into two groups: group I: 27 patients, received OPCAB + MVR, and group II (control group): 26 patients with on-pump myocardial revascularization (ONCAB) + MVR. RESULTS: The aortic cross-clamp (ACC) and cardio-pulmonary bypass (CPB) times were longer in group II, 47.0 (44.0; 55.0) vs 94.5 (89.75; 105.5) minutes, P < .05 and 70.0 (63.0; 77.0) vs 138.5 (127.0; 157.5) minutes, P < .05, respectively. Evaluation of major clinical events showed that the implementation of the off-pump stage of myocardial revascularization in patients with severe IMR did not lead to significant changes in the mortality and postoperative complications. Furthermore, its use did not affect the volume of blood loss and need for blood transfusion, the duration of mechanical ventilation, the need for inotropic therapy, as well as the duration of the patient's resuscitation and the total duration of hospitalization, with the one exception: the troponin-T level increase in the OPCAB + MVR group was less than in the ONCAB + MVR group. CONCLUSION: OPCAB combined MVR in patients with CAD and severe IMR can be performed with shorter CPB and ACC times, and lower troponin-T level after surgery, without reducing the risk of surgical complications.

RESUMEN

BACKGROUND AND AIM OF THE STUDY: Minimally invasive cardiac surgery (MICS) for mitral valve repair (MVRp) has been increasingly used. This study aimed to evaluate the early and late results of MICS for MVRp vs conventional sternotomy. MATERIALS AND METHODS: A systematic review of randomized controlled trials or observational studies (with matched populations) comparing MICS and conventional MVRp reporting any of the following outcomes: mortality, MVRp failure, complications, blood transfusion, readmission within 30 days after discharge, long-term reoperation for mitral regurgitation, operative times, mechanical ventilation time, intensive care unit (ICU) stay, or hospital stay. The pooled treatment effects were calculated using a random-effects model. RESULTS: Ten studies involving 6792 patients (MICS: 3396 patients; Conventional: 3296 patients) met the eligibility criteria. In the pooled analysis, MICS significantly reduced the risk for blood transfusion (odds ratio [OR], 0.654; 95% confidence interval [CI] 0.462-0.928; P = .017) and readmission within 30 days after discharge (OR, 0.615; 95% 0.456-0.829; P = .001). MICS was associated with a significantly longer cross-clamp time (mean difference 14 minutes; 95% CI, 7.4-21 minutes; P < .001), CPB time (24 minutes; 95% CI, 14-35 minutes; P < .001), and total operative time (36; 95% CI, 15-56 minutes; P < .001), but a significantly shorter ICU stay (-8.5; 95% CI -15; -1.8; P = .013) and hospital stay (-1.3, 95% CI -2.1; -0.45; P = .003). This meta-analysis found no significant difference regarding the risk of in-hospital and long-term mortality, nor complications. CONCLUSIONS: Despite longer operative times, MICS for MVRp reduces ICU and hospital stay, as well as readmission rates and the need for transfusion.

RESUMEN

OBJECTIVE: To determine the feasibility of aortic valve neocuspidization (AVNeo) with glutaraldehyde-treated autologous pericardium. METHODS: One hundred and seventy (170) AVNeo (84 males/86 females) were performed from January 2017 through March 2019 in three centers. All the records were prospectively collected and retrospectively reviewed. RESULTS: Most of the patients were older than 60 years and over 95% were operated for aortic stenosis. Preoperatively, pressure gradients were 69.9±21.3 mmHg for patients with aortic stenosis, and the surgical annular diameter was 21.0±2.0 mm for all patients. Effective orifice area (EOA) and indexed EOA (iEOA) averaged 0.7±0.3 cm2 and 0.4±0.2 cm2/m2 for patients with aortic stenosis before surgery, respectively. There was no conversion to prosthetic aortic valve replacement. Eight patients needed reoperation for bleeding, but no patient needed reoperation due to early infective endocarditis. There were five in-hospital deaths due to noncardiac cause. Compared to preoperative echocardiographic measurements, postoperative peak pressure gradient decreased significantly (-58.7±1.7 mmHg; P<0.001) and reached 11.2±5.6 mmHg, and mean pressure gradient also decreased significantly (-36.8±1.1 mmHg; P<0.001) and reached 6.0±3.5 mmHg. Accordingly, EOA and iEOA increased significantly 2.0 cm2 and 1.0 cm2/m2 (both P<0.001) to reach 2.7±0.6 cm2 and 1.4±0.3 cm2/m2 after surgery, respectively, with minimal significant aortic regurgitation (0.6% > mild). CONCLUSION: AVNeo is feasible and reproducible with good clinical results. Hemodynamically, AVNeo produces immediate postoperative low-pressure gradients, large EOA, and minimal regurgitation of the aortic valve. Further studies are necessary to evaluate mid- and long-term evolution.

RESUMEN

OBJECTIVE: To compare the in-hospital outcomes of a right-sided anterolateral minithoracotomy with those of median sternotomy in patients who received a mitral valve replacement (MVR) because of rheumatic mitral valve stenosis (RMS). METHODS: This is a retrospective analysis of 128 patients (34% male) with RMS between 2011 and 2015. The median age was 53 years (45; 56). The mean ejection fraction was 58.4±6.3%. All the subjects were divided into two groups - Group 1 contained 78 patients who underwent MVR via minithoracotomy (MT-MVR), while Group 2 contained 50 patients who underwent MVR via median sternotomy (S-MVR). RESULTS: In the MT-MVR group, a mechanical prosthesis was implanted in 72% of cases, while it was implanted in 90% of cases in the S-MVR group (P=0.01). The duration of myocardial ischemia was similar (MT-MVR, 77±24 min; S-MVR, 70±18 min) (P=0.09). However, the cardiopulmonary bypass time was lower in the S-MVR group than in the MT-MVR group (99±24 min and 119±34 min, respectively) (P≤0.001). There was no difference in the duration of mechanical ventilation, intensive care unit stay, and hospitalization period. Postoperative blood loss was lower in the MT-MVR group (P≤0.001) than in the S-MVR group. There are no statistically significant differences in postoperative complications (superficial wound infection, stroke, delirium, pericardial tamponade, pleural puncture, acute kidney insufficiency, and implantation of pacemaker). The overall in-hospital mortality was 3.9% (P=0.6). CONCLUSION: The minimally invasive approach for RMS is feasible and has an excellent cosmetic effect without increasing the risk of surgical complications.

RESUMEN

OBJECTIVE: The main purpose of this article is to evaluate an impact of epicardial ligation of the left atrial appendage (LAA) in patients with atrial fibrillation (AF) undergoing off-pump coronary artery bypass grafting (OPCAB) on the development of ischemic stroke and mortality. METHODS: From 2009 to 2013, a total of 125 patients (86.4% men, mean age 64 ± 7 years, 95% confidence interval: 61-65 years) received a combined OPCAB and LAA ligation because of coronary artery disease and AF. All the subjects were divided into two groups: group 1 (n = 57)-LAA ligation during OPCAB, group 2 (n = 68) without LAA ligation during OPCAB. Primary endpoints were postoperative incidence of ischemic stroke and mortality. RESULTS: No difference in the number of ischemic stroke (0 vs. 5.9%) and death (0 vs. 4.4%) in both groups during the hospital period (p > 0.05). Median overall follow-up was 41 (22-61) months: without difference for groups (p > 0.05). During follow-up, there was a difference in the number of ischemic stroke (0 vs. 17.6%, p < 0.001), while there was no difference in mortality in two study groups (5.3 vs. 16.2%, p > 0.05). CONCLUSION: Epicardial ligation of LAA during OPCAB in patients with AF may reduce the risk of ischemic stroke in long-term follow-up and does not affect the mortality.

RESUMEN

In cases of aortic valve disease, prosthetic valves have been increasingly used for valve replacement, however, there are inherent problems with prostheses, and their quality in the so-called Third World countries is lower in comparison to new-generation models, which leads to shorter durability. Recently, transcatheter aortic valve replacement has been explored as a less invasive option for patients with high-risk surgical profile. In this scenario, aortic valve neocuspidization (AVNeo) has emerged as another option, which can be applied to a wide spectrum of aortic valve diseases. Despite the promising results, this procedure is not widely spread among cardiac surgeons yet. Spurred on by the last publications, we went on to write an overview of the current practice of state-of-the-art AVNeo and its results.

RESUMEN

BACKGROUND: To investigate whether preoperative short-term extracorporeal life support therapy in patients undergoing continuous-flow left ventricular assist device implantation has an impact on the outcome regarding survival and adverse events. METHODS: Between January 2011 and May 2018, 100 consecutive patients received HeartMate II, HeartWare, or HeartMate III for end-stage heart failure. Mean age was 64.2 ± 10.3 years. Three patient groups were identified: without preoperative extracorporeal life support (non-extracorporeal life support group, n = 80), with preoperative extracorporeal life support due to postcardiotomy shock after conventional cardiac surgery (postcardiotomy shock group, n = 9), and with preoperative extracorporeal life support without previous surgery (non-postcardiotomy shock group, n = 11). The primary endpoint was overall survival after device implantation. Secondary endpoints were adverse events during the follow-up period. RESULTS: Survival was significantly different between the groups (p < 0.05): 30-day, 6-month, and 1-year survival rates were 85%, 68%, and 61% for non-extracorporeal life support group; 44%, 22%, and 22% for postcardiotomy shock group; and 45%, 27%, and 24% for non-postcardiotomy shock group, respectively. Furthermore, in both extracorporeal life support groups (postcardiotomy shock and non-postcardiotomy shock), there were a higher incidence (p < 0.05) of postoperative right heart failure (30% vs 66.7% vs 54.5%), acute renal failure requiring dialysis (20% vs 77.8% vs 54.5%), and respiratory failure (31.3% vs 88.9% vs 81.8%). CONCLUSION: Continuous-flow left ventricular assist device implantation with prior extracorporeal life support appears to have a worse outcome regarding survival, right heart failure, renal and respiratory dysfunction (p < 0.05). Future studies have to be done to evaluate the outcome after extracorporeal life support bridge pre-left ventricular assist device, especially as ultima ratio in postcardiotomy shock patients.
