Preoperative evaluation before MitraClip®: present and future perspective.

2014

ABSTRACT  Mitral regurgitation (MR) is the second most common heart valve disease worldwide. Currently, the management of MR is based on medical therapy (including biventricular pacing), surgery (mitral valve replacement or repair) and percutaneous therapy. However, in spite of guideline recommendations, 50% of individuals assessed in the Euro Heart Survey were not referred to surgical intervention due to comorbidities or real or perceived high risks for cardiac surgery; thus, in recent years, the focus of research has shifted to the development of percutaneous approaches to treat severe MR in order to restore valve function in a minimally invasive fashion. Among these techniques, the perc…

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…

A Comparison of 2 Mitral Annuloplasty Rings for Severe Ischemic Mitral Regurgitation: Clinical and Echocardiographic Outcomes.

2016

Controversies regarding the choice of annuloplasty rings for treatment of ischemic mitral regurgitation still exist. Aim of the study is to compare early performance of 2 different rings in terms of rest and exercise echocardiographic parameters (transmitral gradient, systolic pulmonary artery pressure, and mitral valve area), clinical outcomes, and recurrence of mitral regurgitation. From January 2008 till December 2013, prospectively collected data of patients who underwent coronary artery bypass grafting and undersizing mitral valve annuloplasty for severe chronic ischemic mitral regurgitation at our Institution were reviewed. A total of 93 patients were identified; among them 44 had sem…

Associations of rs3918242 and rs2285053 MMP-9 and MMP-2 polymorphisms with the risk, severity, and short- and long-term complications of degenerative…

2016

Abstract Background Degenerative forms of mitral valve diseases (MVDs) are very complex pathologies. Thus, it is difficult to make generalizations about the disease pathways or genetic risk factors contributing to these diseases. However, a key role of metalloproteinases (MMPs) in their pathophysiology is emerging. Thus, we performed for the first time a perspective study to assess eventual associations of some functional single nucleotide polymorphisms (SNPs) in MMP-2 and MMP-9 genes with the MVD risk, symptom severity, and short- and long-term (4.8 years) complications. Materials and methods For this purpose, 90 patients and two control groups were genotyped for rs3918242, rs243865, and r…

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…

Papillary muscle relocation in conjunction with valve annuloplasty improve repair results in severe ischemic mitral regurgitation

2012

OBJECTIVE: The incidence of recurrent mitral regurgitation (MR) after restrictive annuloplasty (RA) was 5% to 20% in several reports. There are many opinions in favor of adding subvalvular procedures to RA to reduce the tenting forces and improve the repair results. METHODS: From March 2003 to May 2010, 55 patients with severe ischemic MR who had undergone papillary muscle (PPM) relocation in conjunction with mitral annuloplasty in our institutions were enrolled. The patients were matched 1:1 with those who underwent isolated RA using the propensity score. The mean left ventricular ejection fraction was 42% ± 6%. The mean tenting area and coaptation depth was 3.2 ± 0.6 cm(2) and 1.3 ± 0.2 c…
