Gradual dilatation of the neo-aortic/pulmonary root or development of an autograft aneurysm and associated valve regurgitation is a major fear and a serious late complication after the Ross procedure to preserve the "principle of a living valve" after the Ross operation by performing the valve-sparing reimplantation technique (David procedure). This article addresses the main peculiarities of this redo scenario compared to a primary/standard David procedure.

We report a technique for distal body perfusion in an infant with hypoplastic aortic arch and isthmus stenosis by ultrasound- guided cannulation of the femoral artery using an intra-arterial vascular sheath establishing whole-body perfusion by triple cannulation.

Selective antegrade cerebral perfusion has been reported to improve organ function during this procedure. Visceral perfusion can be optimized by cannulation of the descending aorta during infant aortic arch surgery, leading to a decrease in end organ damage.

Theoretically, the "living valve" principle of the Ross operation may represent a potentially viable solution to this dilemma. In this paper, we report on the surgical techniques of the Ross procedure and present long-term post-operative outcomes using the reinforced full-root technique.

Background: Mitral valve (MV) repair with annuloplasty is the standard of care in patients with primary degenerative mitral regurgitation (DMR). Newer generations of annuloplasty rings have been developed with the goals of closer reproduction of native annular geometry and easier implantation. This study investigates the short-term and 5-year clinical outcomes of MV repair with the Carpentier-Edwards (CE) Physio II annuloplasty ring.

Mitral regurgitation is common and is associated with excess morbidity and mortality. Despite these poor outcomes, only a minority of affected patients undergo mitral surgery, for several reasons, which underlines the substantial unmet need for treatment for this disorder. Transcatheter mitral valve repair interventions have been developed to treat mitral regurgitation in an undertreated patient population.

The aim of this study was to compare the long-term results of loop neochord replacement with leaflet resection techniques in patients undergoing minimally invasive mitral valve (MV) repair for MV prolapse.
Methods: Between 1999 and 2014, 2134 consecutive MV prolapse patients underwent minimally invasive MV repair with isolated loop (n = 1751; 82.

Purpose: This study aims to analyze the clinical outcomes after isolated mitral valve (MV) repair in patients with reduced left ventricular ejection fraction (LVEF <50%) with focus on perioperative characteristics, survival, and freedom from reoperations.
Methods: Between 1997 and 2015, 557 patients with reduced LVEF (age: 62.8 ± 11.

Objectives: Mitral valve (MV) annuloplasty ring dehiscence with subsequent recurrent mitral regurgitation represents an unusual but challenging clinical problem. Incidence, localization and outcomes for this complication have not been well defined.
Methods: From 1996 to 2016, a total of 3478 patients underwent isolated MV repair with ring annuloplasty at the Leipzig Heart Centre.
Objectives: The goal of this study was to quantify the mitral valve (MV) annulus, the MV shape and the anatomical MV orifice area throughout the cardiac cycle using 4-dimensional MV analysis software in patients with primary mitral regurgitation (PMR) and secondary mitral regurgitation (SMR) in comparison to a healthy control group.
Methods: Three-dimensional transoesophageal echocardiograms of the MV were acquired for 29 patients with PMR, for 28 patients with SMR and for 18 healthy control subjects. The MV was quantified with regards to anterior-posterior and lateromedial diameter, annular area and circumference, intertrigonal (IT) distance, annular sphericity index, annular height to commissural width ration, and anatomical MV orifice area throughout the cardiac cycle using 3-dimensional transoesophageal echocardiography-based 4-dimensional MV advanced analysis software.
Background: The aim of this study was to quantify the acute dynamic changes of mitral valve (MV) geometry throughout the cardiac cycle-during percutaneous MV repair with the MitraClip system by 3-dimensional transesophageal echocardiography (3D TEE).
Methods: The MV was imaged throughout the cardiac cycle (CC) before and after the MitraClip procedure using 3D TEE in 28 patients (mean age, 77 ± 8 years) with functional mitral regurgitation (FMR). Dynamic changes in the MV annulus geometry and anatomical MV orifice area (AMVOA) were quantified using a novel semi-automated software.
Mohs micrographic surgery (MMS) is a challenging procedure to conceptualize, yet it is an integral component of dermatology residency. The cantaloupe analogy is a tool that can be used to assist in visualizing MMS specimen processing, which transitions the 3-dimensional multilayered skin to a 2-dimensional histologic slide.

Methods: Twenty-nine patients (63 ± 10 years) with severe primary mitral regurgitation underwent surgical MVR using ring annuloplasty with or without neochord implantation. We recorded 3D TEE data throughout the cardiac cycle before and after MVR.
Mitral valve (MV) insufficiency, classified as primary and secondary mitral regurgitation (MR), is a common cause of morbidity and mortality. In industrialized countries, degenerative forms are the predominant cause of MR; however, an increasing number of patients present with secondary MR (Iung et al. EHJ 24:1231-1243, 2003).
View Article and Find Full Text PDFObjectives: The present study aimed to test the clinical benefit of combined transcatheter mitral plus tricuspid valve edge-to-edge repair (TMTVR) as compared with transcatheter mitral valve edge-to-edge repair (TMVR) alone in patients with both significant mitral (MR) and tricuspid regurgitation (TR) at high surgical risk.
Background: A growing number of patients with severe MR at increased surgical risk are treated by transcatheter techniques. Evidence suggests that residual TR remains a predictor of adverse outcome in these patients.
Background: Transapical, beating heart, off-pump implantation of neochordae for repair of mitral valve (MV) prolapse is of increasing interest. The aim of this study was to evaluate long term results for MV repair using the NeoChord system (NeoChord, St. Louis Park, MN).

Aims: Results of catheter based interventional treatment for pulmonary vein stenosis (PVS) following radiofrequency ablation (RFA) for atrial fibrillation remain suboptimal. Surgical repair may represent an alternative therapy, though long-term results have not been thoroughly investigated.
Methods And Results: We retrospectively assessed all patients in our centre undergoing surgical repair for radiofrequency-induced PVS.
Aims: Severe tricuspid regurgitation (TR) is common in patients with right-sided heart failure (HF) and causes substantial morbidity and mortality. Treatment options beyond medical therapy are limited for high-risk patients. Transcatheter edge-to-edge tricuspid valve (TV) repair showed procedural safety and short-term efficacy.
View Article and Find Full Text PDFRobotic and minimally invasive mitral valve (MV) procedures have been performed with increasing frequency over time. These alternatives offer similar efficacy to that achieved via standard median sternotomy, particularly in large volume centers, along with low perioperative morbidity and mortality rates. Moreover, patient acceptance is oftentimes increased due to less postoperative pain and shorter recovery times, as well as superior cosmetic results.
