Functional annulus remodelling using a prosthetic ring in tricuspid aortic valve repair: mid-term results

2013

OBJECTIVES: The functional aortic valve annulus (FAVA) is a complex unit with proximal (aorto-ventricular junction) and distal (sinotubular junction) components. The aim of our study was to evaluate the impact of the total FAVA remodelling, using a prosthetic ring, on mid-term clinical and echocardiographic-RESULTS:-after aortic valve repair. METHODS: Since February 2003, 250 patients with tricuspid aortic valve insufficiency (AI) underwent aortic valve repair. FAVA dilatation was treated by prosthetic ring in 52 patients, by isolated subcommissural plasty in 62, by subcommissural plasty plus ascending aortic replacement in 57 and by David's reimplantation procedure in 79. Survival rate and…

Clinical and echocardiographic outcomes of transcatheter mitral valve repair in atrial functional mitral regurgitation.

2021

Background: Isolated atrial fibrillation can cause mitral regurgitation (MR) in patients with normal left ventricular systolic function and no organic disease of the mitral valve. Little information is available regarding outcomes of Mitraclip in patients with atrial functional mitral regurgitation (AFMR). We aimed to evaluate 12-month clinical and echocardiographic outcomes of transcatheter mitral valve repair (TMVR) with MitraClip in patients with AFMR compared to those with ventricular functional or degenerative/mixed MR. Methods: Registry-based analysis of all consecutive patients who underwent TMVR and were included in the Spanish Registry of Mitraclip. Changes in MR and NYHA functiona…

12‐Month outcomes of transcatheter tricuspid valve repair with the PASCAL system for severe tricuspid regurgitation

2021

Objectives We investigated the durability of tricuspid regurgitation (TR) reduction and the clinical outcomes through 12 months after transcatheter tricuspid valve repair (TTVr) with the PASCAL Transcatheter Valve Repair System. Background TTVr has rapidly developed and demonstrated favorable acute outcomes, but longer follow-up data are needed. Methods Overall, 30 patients (age 77 ± 6 years; 57% female) received PASCAL implantation from September 2017 to May 2019 and completed a clinical follow-up at 12 months. Results The TR etiology was functional in 25 patients (83%), degenerative in three (10%), and mixed in two (7%). All patients had TR severe or greater (massive or torrential in 80%)…

Predictors of short‐ and long‐term outcomes of patients undergoing transcatheter mitral valve edge‐to‐edge repair

2020

Objectives Transcatheter mitral valve repair (TMVR) by edge-to-edge therapy is an established treatment for severe mitral valve regurgitation (MR). Background Symptomatic and prognostic benefit in functional MR has been shown recently; nevertheless, data on long-term outcomes are sparse. Methods and results We analyzed survival of patients treated with isolated edge-to-edge repair from June 2010 to March 2018 (primarily combined edge-to-edge repair with other mitral valve interventions was excluded) in a retrospective monocentric study. Overall, 627 consecutive patients (47.0% females, 78.6 years in mean) were included. Leading etiology was functional MR (57.4%). Follow-up regarding surviva…

Relocation of Papillary Muscles for Ischemic Mitral Valve Regurgitation

2014

Objective The assessment of the mitral valve apparatus (MVA) and its modifications during ischemic mitral regurgitation (IMR) is better performed by three-dimensional (3D) transesophageal echocardiography (TEE). The aim of our study was to carry out nonrestrictive mitral annuloplasty in addition to relocation of papillary muscles (PPMs) oriented by preoperative real-time 3D TEE through the mitral valve quantification dedicated software. Methods Since January 2008, a total of 70 patients with severe IMR were examined both before and after mitral valve repair. The mean (SD) coaptation depth and the mean (SD) tenting area were 1.4 (0.4) cm and 3.2 (0.5) cm2, respectively. Intraoperative 3D TEE…

Impact of moderate ischemic mitral regurgitation after isolated coronary artery bypass grafting

2009

The aim of the study was to evaluate the clinical and echocardiographic outcomes, at rest and under exercise testing, of patients with moderate ischemic mitral regurgitation (IMR) undergoing isolated coronary artery bypass graft surgery (CABG).Between February 2003 and March 2008, 180 patients with moderate IMR who had isolated CABG were enrolled. Patients were matched 1:2 (n = 360) with patients who underwent isolated CABG without IMR (by propensity score). The study endpoints were freedom from all death, cardiac related-death, late events, and cardiac-related events. Late outcomes and left ventricular remodeling were evaluated according to preoperative percent of ejection fraction. Sympto…

Results of mitral valve repair for Barlow disease (bileaflet prolapse) via right minithoracotomy versus conventional median sternotomy: a randomized …

2011

Objective: The results of mitral repair for complex Barlow valves are adequate and support earlier intervention. It is unknown whether these results are reproducible in the context of minimally invasive surgery via right minithoracotomy. Methods: We randomized patients with Barlow mitral disease (bileaflet prolapse) to have conventional open repair via median sternotomy (MS group) or minimally invasive (MI group) repair. Repair was done using polytetrafluoroethylene chordal reimplantation for both leaflets. In the MI group, we adopted right minithoracotomy, peripheral cannulation, external aortic clamping, and surgery under direct vision. Results: Both groups comprised 70 patients. The oper…

Cardiopulmonary Hemodynamic Profile Predicts Mortality After Transcatheter Tricuspid Valve Repair in Chronic Heart Failure.

2020

This study was designed to assess hemodynamic changes in response to transcatheter tricuspid valve edge-to-edge repair (TTVR) and to identify hemodynamic predictors associated with mortality.Severe tricuspid regurgitation (TR) is associated with high mortality. TTVR effectively alleviates heart failure symptoms, but comprehensive hemodynamic characterization of patients undergoing TTVR is currently lacking.This international, multicenter study included 236 patients undergoing TTVR. Data from clinical assessment, echocardiography, intraprocedural right heart catheterization, and noninvasive cardiac output measurement were analyzed. Hemodynamic predictors for mortality were identified using l…

Three-Year Results of Repaired Barlow Mitral Valves via Right Minithoracotomy versus Median Sternotomy in a Randomized Trial

2012

<b><i>Objectives:</i></b> To clarify whether the results of repair of a complex mitral lesion (Barlow valve) at the intermediate-term follow-up are independent of the mode of surgical access [minithoracotomy vs. median sternotomy (MS)]. <b><i>Methods:</i></b> In a prospective randomized study of mitral repair for Barlow disease using either a minimally invasive (MI) approach or MS, we achieved an average follow-up of 3 years (echocardiography, physical examination and quality of life). Mitral repair was achieved with polytetrafluoroethylene chordal implantation for both leaflets. <b><i>Results:</i></b> Both groups inclu…
