RESUMEN

Introduction: Reconstruction surgery of the proximal aorta in most cases involves the use of an aortic conduit, followed by reimplantation of the coronary ostia. Although uncommon, the origin of the coronary arteries in certain anatomical variants poses additional difficulties when performing surgery on the aortic root and requires a different treatment rationale. Case report: We hereby present the case of a 60-year-old patient with multiple cardiovascular risk factors (smoking, arterial hypertension and dyslipidemia), suffering from severe degenerative stenosis of a bicuspid aortic valve, associated with ascending aorta aneurysm and a significant extrinsic stenosis of the left coronary artery caused by the aneurysm. The patient presented with severe degenerative bicuspid aortic valve stenosis associated with ascending aorta aneurysm and a significant extrinsic stenosis of the left coronary artery caused by the aneurysm. Following the preoperative assessment, it was decided that the best course of action was to perform surgery on the aortic valve and ascending aorta. During the surgery, the origin of the right and left coronary ostia were found at the level of the left coronary cusp, both forming a common coronary button. Due to this particular anatomical variant, it was decided to reimplant them as a common button onto the main conduit by means of an interposed No.10 PTFE (Polytetrafluoroethylene) vascular prosthesis. Conclusion: A rare case of aortic root surgery associated with coronary ostia origin variant "shotgun barrel", which required a different method of reimplantation: modified Cabrol technique.

RESUMEN

The cardiac outflow tract (OFT) transiently links the ventricles to the aortic sac and forms the arterial valves. Abnormalities in these valves, such as bicuspid aortic valve (BAV), are common congenital anomalies. GATA6-inactivating variants cause cardiac OFT defects and BAV, but their mechanisms are unclear. We generated Gata6STOP/+ mice using CRISPR-Cas9, which show highly penetrant BAV (70%) and membranous ventricular septal defects (43%). These mice exhibited decreased proliferation and increased ISL1-positive progenitor cells in the OFT, indicating abnormal cardiovascular differentiation. Gata6 deletion with the Mef2cCre driver line recapitulated Gata6STOP/+ phenotypes, indicating a cell-autonomous role for Gata6 in the second heart field. Gata6STOP/+ mice showed reduced OFT length and caliber, associated with deficient cardiac neural crest cell contribution, which may cause valvulo-septal defects. RNA-sequencing analysis showed depletion in pathways related to cell proliferation and migration, highlighting Cxcr7 (also known as Ackr3) as a candidate gene. Reduced mesenchymal cell migration and invasion were observed in Gata6STOP/+ OFT tissue. CXCR7 agonists reduced mesenchymal cell migration and increased invasion in wild-type but not in Gata6STOP/+ explants, indicating the GATA6-dependent role of CXCR7 in OFT development and its potential link to BAV.

RESUMEN

Although mitral annular calcification is a common degenerative condition of the fibrous mitral annulus, tricuspid annular calcification, especially isolated, is rare. We report the case of a 73-year-old male, with a history of hypertension and severe kyphoscoliosis, referred to the emergency department for progressive dyspnea and leg swelling. Echocardiography revealed a dilated right heart with a homogeneous, hyperechoic, crescent shaped mass along the tricuspid annulus. Computed tomography confirmed the calcific nature of the lesion. Right heart catheterization revealed mild pre-capillary pulmonary hypertension and a mild spirometrically-defined restrictive ventilatory defect. Kyphoscoliosis has recently been associated with alterations in cardiac deformation and with an increased risk of restrictive lung disease. In our patient, we hypothesized that both these anomalies could have led to premature tricuspid annular degeneration resulting in a giant tricuspid calcification.

RESUMEN

Bicuspid aortic valve (BAV), the most common congenital heart defect, is a major cause of aortic valve disease requiring valve interventions and thoracic aortic aneurysms predisposing to acute aortic dissections. The spectrum of BAV ranges from early onset valve and aortic complications (EBAV) to sporadic late onset disease. Rare genomic copy number variants (CNVs) have previously been implicated in the development of BAV and thoracic aortic aneurysms. We determined the frequency and gene content of rare CNVs in EBAV probands (n = 272) using genome-wide SNP microarray analysis and three complementary CNV detection algorithms (cnvPartition, PennCNV, and QuantiSNP). Unselected control genotypes from the Database of Genotypes and Phenotypes were analyzed using identical methods. We filtered the data to select large genic CNVs that were detected by multiple algorithms. Findings were replicated in a BAV cohort with late onset sporadic disease (n = 5040). We identified 3 large and rare (< 1,1000 in controls) CNVs in EBAV probands. The burden of CNVs intersecting with genes known to cause BAV when mutated was increased in case-control analysis. CNVs intersecting with GATA4 and DSCAM were enriched in cases, recurrent in other datasets, and segregated with disease in families. In total, we identified potentially pathogenic CNVs in 9% of EBAV cases, implicating alterations of candidate genes at these loci in the pathogenesis of BAV.

RESUMEN

BACKGROUND: Research on the role of transcatheter heart valve (THV) deformation and calcium distribution in patients with bicuspid aortic valves (BAVs) undergoing transcatheter aortic valve replacement (TAVR) remains limited. OBJECTIVES: The aim of this study was to evaluate the impact of THV deformation on clinical outcomes in individuals with BAVs undergoing TAVR and the influence of calcium on these outcomes. METHODS: In total, 229 consecutive patients with BAVs who underwent TAVR with balloon-expandable valves and had computed tomography (CT) performed 30 days post-TAVR were analyzed. Patients were stratified into 3 groups: group 1 (n = 125), with no THV underexpansion or eccentricity; group 2 (n = 69), with underexpansion or eccentricity; and group 3 (n = 35), with both. Calcium distribution was assessed using CT, and its associations with clinical outcomes, including all-cause mortality at 3 years and leaflet thrombosis at 30 days, were determined. A subgroup analysis of patients with type 1 BAVs was conducted. RESULTS: Group 3 exhibited higher rates of all-cause mortality than the other groups, along with the highest risk for hypoattenuated leaflet thickening at 30 days. Multivariate analysis identified annular and left ventricular outflow tract calcification as independent predictors of all-cause mortality and hypoattenuated leaflet thickening. In patients with type 1 BAVs, excessive calcification at the raphe and opposite leaflet were associated with all-cause mortality at 3 years. CONCLUSIONS: THV deformation post-TAVR was significantly linked to all-cause mortality in patients with BAVs. Annular and left ventricular outflow tract calcification correlated with increased risks for all-cause mortality and leaflet thrombosis.

RESUMEN

INTRODUCTION: Stroke is a potentially debilitating complication of heart valve replacement surgery, with rates ranging from 1 to 10%. Despite advancements in surgical techniques, the incidence of postoperative stroke remains a significant concern, impacting patient outcomes and healthcare resources. This study aims to investigate the incidence, risk factors, and outcomes of in-hospital adverse neurologic events, particularly stroke, following valve replacement. The analysis focuses on identifying patient characteristics and procedural factors associated with increased stroke risk. METHODS: This retrospective study involves a review of 417 consecutive patients who underwent SVR between January 2004 and December 2022. The study cohort was extracted from a prospectively recorded cardiac intensive care unit database. Preoperative and perioperative data were collected, and subjects with specific exclusion criteria were omitted from the analysis. The analysis includes demographic information, preoperative risk factors, and perioperative variables. RESULTS: The study identified a 4.3% incidence of postoperative stroke among SVR patients. Risk factors associated with increased stroke susceptibility included prolonged cardiopulmonary bypass time, aortic cross-clamp duration exceeding 90 min, prior stroke history, diabetes mellitus, and mitral valve annulus calcification. Patients undergoing combined procedures, such as aortic valve replacement with mitral valve replacement or coronary artery bypass grafting with AVR and MVR, (OR = 10.74, CI:2.65-43.44, p-value = < 0.001) and (OR = 11.66, CI:1.02-132.70, p-value = 0.048) respectively, exhibited elevated risks. Internal carotid artery stenosis (< 75%) and requiring prolonged inotropic support were also associated with increased stroke risk(OR = 3.04, CI:1.13-8.12, P-value = 0.026). The occurrence of stroke correlated with extended intensive care unit stay (OR = 1.12, CI: 1.04-1.20, P-value = 0.002) and heightened in-hospital mortality. CONCLUSION: In conclusion, our study identifies key risk factors and underscores the importance of proactive measures to reduce postoperative stroke incidence in surgical valve replacement patients.

RESUMEN

BACKGROUND: Current cardiovascular prevention strategies are based on studies that seldom include valvular heart disease (VHD). The role of modifiable lifestyle factors on VHD progression and life expectancy among the elderly with different socioeconomic statuses (SES) remains unknown. METHODS: This cohort study included 164,775 UK Biobank participants aged 60 years and older. Lifestyle was determined using a five-factor scoring system covering smoking status, obesity, physical activity, diet, and sleep patterns. Based on this score, participants were then classified into "poor," "moderate," or "ideal" lifestyle groups. SES was classified as high or low based on the Townsend Deprivation Index. The association of lifestyle with major VHD progression was evaluated using a multistate mode. The life table method was employed to determine life expectancy with VHD and without VHD. RESULTS: The UK Biobank documented 5132 incident VHD cases with a mean follow-up of 12.3 years and 1418 deaths following VHD with a mean follow-up of 6.0 years. Compared to those with a poor lifestyle, women and men followed an ideal lifestyle had lower hazard ratios for incident VHD (0.66 with 95% CI, 0.59-0.73 for women and 0.77 with 95% CI, 0.71-0.83 for men) and for post-VHD mortality (0.58 for women, 95% CI 0.46-0.74 and 0.62 for men, 95% CI 0.54-0.73). When lifestyle and SES were combined, the lower risk of incident VHD and mortality were observed among participants with an ideal lifestyle and high SES compared to participants with an unhealthy lifestyle and low SES. There was no significant interaction between lifestyle and SES in their correlation with the incidence and subsequent mortality of VHD. Among low SES populations, 60-year-old women and men with VHD who followed ideal lifestyles lived 4.2 years (95% CI, 3.8-4.7) and 5.1 years (95% CI, 4.5-5.6) longer, respectively, compared to those with poor lifestyles. In contrast, the life expectancy gain for those without VHD was 4.4 years (95% CI, 4.0-4.8) for women and 5.3 years (95% CI, 4.8-5.7) for men when adhering to an ideal lifestyle versus a poor one. CONCLUSIONS: Adopting a healthier lifestyle can significantly slow down the progression from free of VHD to incident VHD and further to death and increase life expectancy for both individuals with and without VHD within diverse socioeconomic elderly populations.

RESUMEN

Heart valve disease patients undergo multiple surgeries to replace structurally degraded valve prostheses, highlighting the need for valve replacements with growth and self-repair capacity. Given allogeneic valve transplantation's promise in meeting these goals by delivering a living valve replacement, we propose a framework for preserving and rehabilitating living valves ex vivo.

RESUMEN

BACKGROUND: Transthoracic echocardiography (TTE) is essential in the diagnosis of cardiovascular diseases (CVD), including but not limited to heart failure (HF) and heart valve disease (HVD). However, its dependence on expert acquisition means that its accessibility in rural areas may be limited, leading to delayed management decisions and potential missed diagnoses. Artificial intelligence-guided (AI)-TTE offers a solution by permitting non-expert image acquisition. The impact of AI-TTE on the timing of diagnosis and early initiation of cardioprotection is undefined. METHODS: AGILE-Echo (use of Artificial intelligence-Guided echocardiography to assIst cardiovascuLar patient managEment) is a randomized-controlled trial conducted in 5 rural and remote areas around Australia. Adults with CV risk factors and exercise intolerance, or concerns regarding HVD are randomized into AI-TTE or usual care (UC). AI-TTE participants may have a cardiovascular problem excluded, identified (leading to AI-guided interventions) or unresolved (leading to conventional TTE). UC participants undergo usual management, including referral for standard TTE. The primary endpoint is a composite of HVD or HF diagnosis at 12-months. Subgroup analysis, stratified based on age range and sex, will be conducted. All statistical analyses will be conducted using R. RESULTS: Of the first 157 participants, 78 have been randomized into AI-TTE (median age 68 [IQR 17]) and 79 to UC (median age 65 [IQR 17], P = .034). HVD was the primary concern in 37 participants (23.6%) while 84.7% (n = 133) experienced exercise intolerance. The overall 10-year HF incidence risk was 13.4% and 20.0% (P = .089) for UC and AI-TTE arm respectively. Atrial remodeling, left ventricular remodeling and valvular regurgitation were the most common findings. Thirty-three patients (42.3%) showed no abnormalities. CONCLUSIONS: This randomized-controlled trial of AI-TTE will provide proof-of-concept for the role of AI-TTE in identifying pre-symptomatic HF or HVD when access to TTE is limited. Additionally, this could promote the usage of AI-TTE in rural or remote areas, ultimately improving health and quality of life of community dwelling adults with risks, signs or symptoms of cardiac dysfunction.

RESUMEN

A young female patient was referred by her general practitioner to the ear, nose and throat outpatient clinic with a 5-year history of progressive hoarseness and loss of voice. A chest radiograph was reported as showing marked dilatation of the left pulmonary artery without any other features to suggest underlying pulmonary arterial hypertension. A provisional diagnosis of left recurrent laryngeal nerve palsy secondary to its compression between the left pulmonary artery and the undersurface of the aortic arch-Ortner's or cardiovocal syndrome-was suggested and confirmed on further investigation including CT, microlaryngoscopy and echocardiography.

RESUMEN

BACKGROUND: Identifying bicuspid aortic valve (BAV) patients at risk for cardiac events remains challenging and the role of the electrocardiogram (ECG) has not yet been described. Therefore, this study aims to describe ECG parameters in BAV patients, and investigate their prognostic value. METHODS: In this single-center prospective study patients with BAV without a prior aortic valve replacement (AVR) were included. Transthoracic echocardiogram and 12­lead resting-ECG were obtained. Associations between ECG parameters and the composite endpoint of all-cause mortality and AVR were assessed using Cox-proportional hazard analysis. RESULTS: 120 patients with BAV were included (median age 30 years, 61% male). Median aortic jet velocity was 2.4 m/s [IQR: 1.7-3.4] and 5 patients (4%) had severe aortic regurgitation. All patients were in sinus rhythm. Any ECG abnormality was present in 57 patients (48%). Median PR-interval was 156 [IQR: 138-170] msec. A deviating QRS axis was found in 17 patients (14%) and Cornell criteria for LVH were fulfilled in 20 patients (17%). Repolarization abnormalities were present in 12 patients (10%). Median follow-up duration was 7.0 [6.3-9.8] years, during which 23 patients underwent AVR and 2 patients died. After adjusting for age, a longer PR-interval was associated with worse intervention-free survival (HR 1.02, 95% CI: 1.01-1.04). CONCLUSION: Almost half of the patients with BAV had abnormalities on their ECG. Moreover, the PR-interval may be an interesting prognostic marker for intervention-free survival in BAV patients.

RESUMEN

Mechanical prosthetic heart valves (MPHVs) are commonly used for valvular heart disease in patients with a long life expectancy. Few longitudinal data on the specific causes of hospitalization in patients with MPHV are available. We investigated the risk of all-cause hospitalization and mortality in patients with MPHV. We performed a prospective, observational, ongoing study including consecutive patients with MPHVs who were referred to the atherothrombosis outpatient clinic of the Policlinico Umberto I of Rome for the vitamin K antagonist management. Study end points were all-cause, cardiovascular hospitalization, and overall mortality. We included 305 patients with MPHV (38.4% women, median age 60.2 years). The site of MPHV was aortic in 53.5%, mitral in 29.5%, and mitroaortic in 17%. During a median follow-up of 57.3 months, 142 hospitalizations occurred (8.16 per 100 person-years). The most common causes of hospitalization were cardiovascular disease (3.62 per 100 person-years), infections, surgery, and bleeding. The predictors of cardiovascular hospitalization were atrial fibrillation (hazard ratio [HR] 1.75, 95% confidence interval [CI] 1.04 to 2.95, p = 0.035), previous stroke/transient ischemic attack (HR 2.96, 95% CI 1.59 to 5.48, p = 0.001), and peripheral artery disease (HR 2.42, 95% CI 1.09 to 5.36, p = 0.030). During a median follow-up of 97.2 months, 61 deaths occurred (2.43 per 100 person-years). Age was directly associated with the risk of death (HR 1.088, 95% CI 1.054 to 1.122, p <0.001), whereas the time in therapeutic range higher than the median was inversely associated (HR 0.436, 95% CI 0.242 to 0.786, p = 0.006). In conclusion, patients with MPHV had a high incidence of hospitalizations, especially cardiovascular-related. The incidence of death is high; however, it may be decreased by maintaining a good quality of anticoagulation.

RESUMEN

Objective: To analysis the risk factors for major adverse cardiovascular event (MACE) in pregnant women with valvular heart disease (VHD) and to construct a risk prediction model. Methods: The clinical data of 245 pregnant women with VHD who were hospitalized in Beijing Anzhen Hospital from January 1, 2012, to June 1, 2023 were retrospectively analyzed, including general information, pre-pregnancy and pregnancy-associated cardiac conditions, and MACE. Univariate analysis and logistic regression models were employed to identify risk factors for MACE during pregnancy among pregnant women with VHD. Furthermore, a predictive model was constructed and internal validation was conducted using bootstrap techniques. Results: (1) Among 245 pregnant women with VHD, the incidence of MACE was 18.0% (44/245), and the most common MACE was heart failure (61.4%, 27/44). The mitral valve was the most frequently affected valve (64.9%, 159/245). Prior to pregnancy, the most common type of valve surgery undertaken was mechanical valve replacement, representing 31.4% (77/245) of surgeries. In contrast, among those pregnant women who did not undergo valve surgery before pregnancy, the most common lesion type was mitral regurgitation (17.6%, 43/245). (2) Comparing the maternal and infant outcomes of warfarin, low molecular weight heparin (LMWH) and LMWH sequential with warfarin, the fetal loss rate (36%, 15/42) and malformation rate (7%, 3/42) were the highest, but the MACE rate (12%, 5/42) was the lowest in warfarin group. The fetal loss rate (1/19), malformation rate (1/19) and artificial valve thrombosis rate (0) of LMWH sequential with warfarin were the lowest, and the fetal loss rate and artificial valve thrombosis rate of the three anticoagulation methods were statistically significant (all P<0.05). (3) There were no significant differences in gestational age, age of diagnosis of heart disease, weight at delivery, pre-pregnancy body mass index, proportion of multiparous women and chronic medical history between women with MACE and those without MACE (all P>0.05). (4) Binary logistic regression analysis identified the following as risk factors for MACE during the second trimester of pregnancy among pregnant women with VHD: pre-pregnancy cardiac symptoms, history of corrective surgery for congenital heart disease, pregnancy risk grade Ⅴ, anticoagulation with LMWH during pregnancy, and arrhythmia (all P<0.05). Based on the results of multivariate analysis, a receiver operating characteristic curve was constructed, with an area under the curve of 0.837, indicating good discriminative ability. The calibration plot demonstrated a close alignment between the standard curve and the calibration prediction curve, suggesting excellent calibration of the model. Conclusions: Pregnant women with VHD are at a high risk of experiencing MACE during gestation. Five risk factors, including pre-pregnancy cardiac symptoms, history of corrective surgery for congenital heart disease, pregnancy risk grade Ⅴ, anticoagulation with LMWH, and arrhythmia, could aid in identifying high-risk pregnant women.

RESUMEN

OBJECTIVES: There remains debate over the optimal mitral valve replacement (MVR) option for patients aged 50-70 years. The objective of this study was to retrospectively compare the long-term outcomes of mechanical and bioprosthetic MVR in this patient population. METHODS: Data from patients undergoing MVR between 2004 and 2018 were retrospectively reviewed. The primary outcome was all-cause mortality. Secondary outcomes included perioperative and late morbidity. RESULTS: Two hundred and eight-six propensity-matched patients (n = 143 mechanical; n = 143 bioprosthetic) aged 50-70 years were included in the final analysis. Maximum follow-up was 15.8 years. There was no significant difference in all-cause mortality between the groups at 30 days, 1 year, 5 years, 10 years, and at the longest follow-up. Patients who underwent mechanical MVR experienced significantly lower rates of postoperative atrial fibrillation (P = 0.001). There were no significant differences in rates of sepsis, acute kidney injury, superficial and deep sternal wound infection, mediastinal bleeding, and permanent pacemaker implantation. At the longest follow-up, there were no differences in myocardial infarction, stroke, heart failure or overall rehospitalization. At the same time point, there was an increased rate of MVR in patients receiving a bioprosthetic valve (P = 0.015). CONCLUSIONS: Survival following mechanical and bioprosthetic MVR in patients 50-70 years of age is similar to up to 15 years of follow-up. Bioprosthetic MVR is associated with an increased risk of repeat MVR. Mechanical MVR is not associated with an increased risk of stroke. Valve selection in this patient population requires diligent consideration of structural valve deterioration and subsequent reoperation risk as well as bleeding and thromboembolic risk.

RESUMEN

Pathologic left ventricular remodeling and valvular heart disease may contribute to the clinical presentation and outcomes of patients presenting with heart failure, and limit the effectiveness of guideline-directed medical therapy. Although surgical interventions including surgical ventricular restoration techniques and valve repair or replacement are effective therapies, there is growing evidence that transcatheter interventions may be options for patients with persistent symptoms of heart failure despite optimal medical therapy, where surgical options may be limited. This scientific statement will review the current available and investigational percutaneous strategies for the management of structural contributors to heart failure: dilated left ventricular cardiomyopathies and valvular heart disease.
