Clinical results of combined aortic valve-sparing root replacement and mitral valve repair.

Objectives: Aortic valve-sparing root replacement using the reimplantation technique and mitral valve repair are well-established surgical approaches for the treatment of aortic root pathologies and mitral valve insufficiency. However, the management of concomitant diseases with a dual valve-preserving strategy remains poorly described. Therefore, the aim of this study is to evaluate the long-term outcomes of concomitant valve sparing surgery and mitral valve repair.

Apical Access Management in Transapical Transcatheter Mitral Valve Replacement.

Background: The role of the surgical technique and anatomy in transapical mitral valve replacement (TA-TMVR) are scarcely investigated.

Methods: Computed tomography scans, surgical reports and planning slides of 127 patients undergoing TA-TMVR with the Tendyne valve system at 15 centers, participating at a European observational study, were retrospectively analyzed and compared between patients with (cohort A) and without (cohort B) apical access complications (AAC).

Results: A total of 8 (6.

Valve-sparing aortic root replacement in bicuspid aortic valves-the reimplantation technique: A multicenter study.

Objective: Reported outcomes in patients with bicuspid aortic valves (BAVs) undergoing valve-sparing aortic root replacement (VSRR) are scarce. This study aims to evaluate outcomes in patients with BAV using the reimplantation (David) technique.

Methods: Consecutive adult patients with BAV, aortic root aneurysm, and/or aortic valve insufficiency (AI) undergoing VSRR (reimplantation) were included from 5 centers experienced in reimplantation procedures.

Aortic root anatomy: insights into annular and root enlargement techniques.

The introduction of the Y(ang)-technique for aortic root enlargement has sparked a renewed interest in annular and root enlargement procedures world-wide. In order to execute these procedures proficiently however, it's important to understand the complex three-dimensional structure of the aortic root and left ventricular outflow tract, and also be familiar with the different enlargement techniques. Herein, we are providing a description of the aortic root anatomy and the most commonly utilized root enlargement procedures.

Tricuspid valve repair for infective endocarditis.

Objectives: The progressive increase in the use of implantable electronic devices, vascular access for dialysis and the increased life expectancy of patients with congenital heart diseases has led in recent years to a considerable number of right-side infective endocarditis, especially of the tricuspid valve (TV). Although current guidelines recommend TV repair for native tricuspid valve endocarditis (TVE), the percentage of valve replacements remains very high in numerous studies. The aim of our study is to analyse our experience in the treatment of TVE with a reparative approach.

Valve-sparing operations after Ross procedure: a single-center experience.

Background: The Ross procedure has demonstrated excellent long-term results, with restoration of life-expectancy in patients with severe aortic valve dysfunction. However, reintervention after Ross can occur, and herein we describe our center's experience with redo surgery after previous Ross procedures.

Methods: We searched our prospective database for aortic valve-repair and recruited all adult (≥18 years) patients who have undergone valve-sparing root replacements (VSRRs) and/or aortic valve-repair after Ross procedure between July 2001 and July 2022.

Intra-operative electroencephalogram frontal alpha-band spectral analysis and postoperative delirium in cardiac surgery: A prospective cohort study.

Background: Postoperative delirium (POD) remains a frequent complication after cardiac surgery, with pre-operative cognitive status being one of the main predisposing factors. However, performing complete pre-operative neuropsychological testing is challenging. The magnitude of frontal electroencephalographic (EEG) α oscillations during general anaesthesia has been related to pre-operative cognition and could constitute a functional marker for brain vulnerability.

Three decades of reimplantation of the aortic valve-the Brussels experience.

Background: Over the last three decades, the importance of native valve preservation has increasingly become evident. Valve-sparing root replacement procedures, such as the reimplantation or remodeling technique, are therefore being progressively used for aortic root replacement and/or aortic valve repair. Herein, we are summarizing our single-center experience with the reimplantation technique.

Functional and pathomorphological anatomy of the aortic valve and root for aortic valve sparing surgery in tricuspid and bicuspid aortic valves.

The aortic valve (AV) is a three-dimensional structure, with leaflets that are suspended within the functional aortic annulus (FAA). These structures (AV and FAA) are therefore intrinsically connected and disease of just one component can independently lead to AV dysfunction. Hence, AV dysfunction can occur in the setting of entirely normal valve leaflets.

Robotic mitral valve repair-the Bruxelles experience.

Background: Although the use of the surgical robot facilitates less invasive mitral valve surgery, both real and perceived limitations have slowed the application of this technology. Aim of the present investigation was to report the early and long-term results of robotic mitral valve repair in a single institution over a 10-year period.

Methods: Between March 2012 and May 2022, a total of 278 consecutive patients underwent robotically assisted mitral valve repair at the Cliniques Universitaires Saint-Luc (Brussels, Belgium).

Predictors of long-term stenosis in bicuspid aortic valve repair.

Objectives: The use of modern techniques for bicuspid aortic valve repair has been shown to provide safe and durable results against recurrent regurgitation. However, an emerging body of evidence is indicating that aortic stenosis might be an additional late complication of these procedures. To date, the pathogenesis and clinical impact of aortic stenosis after bicuspid aortic valve repair are poorly understood.

Congenital unicuspid aortic valve repair without cusp patch augmentation.

Unicuspid aortic valves are rare congenital malformations. Surgical repair is feasible in aortic regurgitation, and in some cases of aortic stenosis. The standard surgical approach is a bicuspidization and symmetrization with pericardial patch augmentation of valve leaflets.

Aortic annulus elevation for aortic valve and root replacement.

Aortic valve and root replacements require an in-depth understanding of the aortic root and annulus. Both structures can be asymmetric at times, and this needs to be recognized and taken into consideration when performing valve-sparing operations or other root-replacement procedures. Moreover, the geometry of the aortic annulus can be altered, and when performing an aortic root replacement this can distort the geometry of a neoaortic valve for instance, and lead to valve dysfunction, which is difficult to reverse.

Myocardial revascularization: Tips and tricks for performing a coronary anastomosis.

Coronary artery bypass graft surgery was performed for the first time in the 1960s [(1]). Today, it is still one of the pillars of cardiac surgery and the most common cardiac operation. Many improvements have been developed since it was first introduced, but such operations remain technically challenging.

Aortic valve repair in endocarditis: scope and results.

Purpose: Infective endocarditis (IE) remains a prevalent and life-threatening disease. The choice to repair or replace the infected valve still remains a matter of debate, especially in aortic valve (AV) infections. We retrospectively analyze our two decades of experience in aortic valve repair (AVr) in IE.

Long-term experience with valve-sparing root reimplantation surgery in tricuspid aortic valve.

Objective: To analyze our long-term experience with valve-sparing reimplantation technique in treating aortic root aneurysm, aortic regurgitation, and aortic dissection in patients with tricuspid aortic valve.

Methods: Between March 1998 and October 2018, 303 consecutive patients underwent valve-sparing reimplantation in our institution. The mean age of this cohort was 52.
