Background: A significant impact of surgeons' experience on outcomes of off-pump coronary artery bypass (OPCAB) has been recognized through previous large-scale studies. However, a safe, effective, and concrete OPCAB training was yet to be identified. We evaluate a safety of our OPCAB training model with single left internal mammary artery (LIMA)-left anterior descending artery (LAD) as a reasonable first step.

Objectives: Post-acute myocardial infarction mechanical complications (post-AMI MCs) represent rare but life-threatening conditions, including free-wall rupture, ventricular septal rupture and papillary muscle rupture. During the coronavirus disease-19 (COVID-19) pandemic, an overwhelming pressure on healthcare systems led to delayed and potentially suboptimal treatments for time-dependent conditions. As AMI-related hospitalizations decreased, limited information is available whether higher rates of post-AMI MCs and related deaths occurred in this setting.
View Article and Find Full Text PDFAims: Many historical and recent reports showed that post-infarction ventricular septal rupture (VSR) represents a life-threatening condition and the strategy to optimally manage it remains undefined. Therefore, disparate treatment policies among different centres with variable results are often described. We analysed data from European centres to capture the current clinical practice in VSR management.

While femoral arterial perfusion is the preferred cannulation strategy in MIS mitral valve surgery, retrograde arterial perfusion is known to be associated with an increased risk for cerebral atheroembolism, particularly in atherosclerosis patients. Therefore, antegrade perfusion may be beneficial in such cases.

Circulating microRNAs (miRs) have been addressed as a novel tool to improve risk stratification in patients with different aortopathies. We aimed to elucidate the correlation between peripheral whole blood and aortic tissue miRs in order to prove the potential availability as a biomarker in the clinical routine.
View Article and Find Full Text PDFImportance: Ventricular septal rupture (VSR) is a rare but life-threatening mechanical complication of acute myocardial infarction associated with high mortality despite prompt treatment. Surgery represents the standard of care; however, only small single-center series or national registries are usually available in literature, whereas international multicenter investigations have been poorly carried out, therefore limiting the evidence on this topic.
Objectives: To assess the clinical characteristics and early outcomes for patients who received surgery for postinfarction VSR and to identify factors independently associated with mortality.
Background: Coronary artery bypass grafting (CABG) without cardiopulmonary bypass and minimal or no aortic manipulation may be associated with a lower risk of neurological complications. We investigated this issue in patients with a high risk of perioperative stroke.
Methods: Data on 7352 patients who underwent isolated CABG from January 2015 to May 2017 were included in the multicenter study E-CABG (European Coronary Artery Bypass Grafting) registry.
Unicuspid aortic valve disease (UAVD) is a frequent and long-lasting challenge for adult congenital heart disease centers. UAVD patients become usually symptomatic in their twenties or thirties and require a surgical treatment plan which should respect their complete lifespan combined with an adequate quality of life. Unfortunately, all current surgical strategies of congenital aortic valve disease bear some important limitations: (I) Aortic valve replacement using bioprosthetic valves is associated with early structural degeneration and leads frequently to re-operations.

Methods: All 65 patients who underwent elective aortic valve repair/replacement +/- proximal aortic replacement due to BAV disease with or without concomitant aortic aneurysm were identified from our BAV registry. Aortic tissue was collected intraoperatively from the ascending aorta at the greater and lesser curvature.

Introduction: While the understanding of the pathophysiology and clinical implication of bicuspid aortic valves evolves rapidly, the natural history of unicuspid aortic valves is still poorly understood. Hence, a universally accepted diagnostic work-up process and therapy recommendations for UAV still have to be established.
Areas Covered: This article aims to give an overview on the most recent literature addressing the pathophysiology, the diagnostic tools and appropriate surgical therapy options of unicuspid aortic valve.

There is growing clinical need and interest to implement novel risk prediction tools in bicuspid aortic valve-associated proximal aortic disease, so-called bicuspid aortic valve aortopathy. Inherent limitations of the diameter-based risk stratification for adverse aortic events in bicuspid aortic valve aortopathy patients have recently been recognized. Therefore, alternative diagnostic tools and subsequent adjustments in the treatment guidelines are urgently needed.
View Article and Find Full Text PDFObjective: Aortic size-based criteria are of limited value in the prediction of aortic events, while most aortic events occur in patients with proximal aortic diameters < 50 mm. Serological biomarkers and especially circulating microRNAs (miRNAs) have been proposed as an elegant tool to improve risk stratification in patients with different aortopathies. Therefore, we aimed to evaluate the levels of circulating miRNAs in a surgical cohort of patients presenting with bicuspid aortic valve disease and distinct valvulo-aortic phenotypes.

: Dilatation of the proximal aorta is often associated with an aortic valve disease (e.g. bicuspid aortic valve, aortic stenosis), so-called 'valve-related aortopathy.
View Article and Find Full Text PDFObjective: Long-term prognosis of patients with aortic regurgitation (AR) and reduced left ventricular ejection fraction (LVEF) who undergo aortic valve surgery (AVS) is unknown. Due to the congenital origin, bicuspid aortic valve (BAV) morphotype might be associated with a more severe cardiomyopathy. We aimed to evaluate the LVEF recovery after aortic valve replacement (AVR) surgery in patients with AR and reduced preoperative LVEF.
View Article and Find Full Text PDFBicuspid aortic valve (BAV) disease is the most common congenital malformation of the human heart with a prevalence of 1⁻2% in the general population. More than half of patients with a BAV present with a dilated proximal aorta (so-called bicuspid aortopathy) which is associated with an enhanced risk of life-threatening aortic complications. Up to now, the pathogenesis of bicuspid aortopathy as well as the risk stratification of aortic complications has not yet been sufficiently clarified.

Background And Aim Of The Study: The ascending aortic dilatation may progress after aortic valve replacement (AVR) in bicuspid aortic valve (BAV) patients. Our aim was to evaluate rheological flow patterns and histological characteristics of the aneurysmal aorta in BAV patients at the time of reoperative aortic surgery.
Materials And Methods: 13 patients (mean age: 42 ± 9 years, 10 (77%) male) with significant progression of proximal aortopathy after isolated AVR surgery for BAV disease (i.
Traditional risk stratification model of bicuspid aortic valve (BAV) aortopathy is based on measurement of maximal cross-sectional aortic diameter, definition of proximal aortic shape, and aortic stiffness/elasticity parameters. However, conventional imaging-based criteria are unable to provide reliable information regarding the risk stratification in BAV aortopathy, especially considering the heterogeneous nature of BAV disease. Given those limitations of conventional imaging, there is a growing clinical interest to use circulating biomarkers in the screening process for thoracic aortic aneurysms as well as in the risk-assessment algorithms.
