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 (MV) 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 MV repair.

Rare Case of Valve-Sparing Root Reimplantation in a Patient With an Anomalous Circumflex Artery.

We present a case of valve-sparing root reimplantation in a patient with severe aortic regurgitation, in the setting of a bicuspid aortic valve with an aberrant circumflex coronary artery arising from the right coronary artery, thus rendering standard dissection of the aortic root during a David procedure challenging and risky.

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.

Current status of aortic valve repair surgery.

Severe aortic valve regurgitation, if not timely treated, can significantly impact patients' survival both for tricuspid aortic valve and bicuspid aortic valve patients, with the latter being significantly younger. Increased understanding of the root anatomy and its physiology has opened the way to techniques of aortic valve repair surgery. The techniques mainly relate to re-establishing a correct root and annular geometry and eliminating leaflet prolapse.

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.

Continuous or interrupted pledgeted suture technique in stented bioprosthetic aortic valve replacement: a comparison of in-hospital outcomes.

Background: There is ambiguity in the literature regarding the continuous suture technique (CST) for aortic valve replacement (AVR). At our center, there has been a gradual shift towards CST over the interrupted pledgeted technique (IPT). This study aims at comparing outcomes for both techniques.

Native Aortic Valve Resection Using a Novel Blade-Based Device.

Objective: The aim of this study was to validate the use of a new resection device in patient candidates for surgical aortic valve replacement. We evaluated the efficacy of this new circular blade to resect the aortic valve and the efficacy to collect the debris during the resection.

Methods: For this study, a single size instrument was used, with an external diameter of 22 mm, and patients were selected on the basis of the preoperative assessment of the aortic diameters.

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.

Tricuspid annular dynamics, not diameter, predicts tricuspid regurgitation after mitral valve surgery: Results from a prospective randomized trial.

Objective: Current guidelines advise using prophylactic tricuspid valve annuloplasty during mitral valve surgery, especially in the presence of annular diameter enlargement. However, several retrospective studies and a prospective randomized study from our department could not confirm that diameter enlargement is predictive of late regurgitation. We examined whether 2- and 3-dimensional echocardiographic and clinical characteristics could identify patients who will develop moderate or severe recurrent tricuspid regurgitation.

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).

A multicentre, propensity score matched analysis comparing a valve-sparing approach to valve replacement in aortic root aneurysm: Insight from the AVIATOR database.

Objectives: Our goal was to evaluate the outcome of valve-sparing root replacement (VSRR) and to compare the outcomes to those of patients having composite valve-graft conduit aortic root replacement (CVG-ARR) in a cohort of patients with aortic root aneurysm ± valve insufficiency, without valvular stenosis. Although valve-sparing procedures are preferable in young patients, there is a lack of comparative data in comparable patients.

Methods: The VSRR procedures were performed in 2005 patients, and 218 patients underwent a CVG-ARR procedure.

Bicuspid aortic valve repair: the 180°-Reimplantation technique.

Bicuspid aortic valves (BAVs) represent a wide spectrum of aortic valve phenotypes. We have therefore previously proposed a new repair-oriented surgical classification for BAVs in order to facilitate our understanding of any given phenotype and to guide surgical repair. BAVs can range from symmetric to very asymmetric, and classification is determined by commissural orientation.
