Degenerative mitral valve (MV) disease causing mitral regurgitation (MR) is the most common organic valve pathology and is classified based on leaflet motion. MV repair is indicated as the preferred technique (Class I indication) when the results are expected to be durable. Therefore, a detailed and systematic evaluation of MV apparatus is pivotal in allowing the proper surgical planning, as well as the screening for trans catheter-based treatment when surgery is not indicated.
Three-dimensional saddle-shaped annuloplasty rings have been shown to create a larger surface of leaflet coaptation in mitral valve repair (MVR) for functional mitral regurgitation (FMR) and degenerative mitral regurgitation (DMR) which may increase repair durability. For the first time, this study reports mid-term results after MVR for DMR and FMR using a rigid three-dimensional ring (Profile 3D, Medtronic).
The fate of unrepaired tricuspid regurgitation (TR) after mitral repair (MVr) for degenerative mitral regurgitation (MR) remains highly debated. The objective of this study was to examine the progress of unrepaired TR after MVr for degenerative MR, with a particular focus on comparing patients with moderate preoperative TR to those having none or mild preoperative TR.
This study was performed to determine if strain can supplement the ability of left ventricular ejection fraction (LVEF) to predict post-op ventricular dysfunction in patients undergoing mitral valve (MV) surgery for degenerative mitral regurgitation (DMR).
Most patients with severe degenerative mitral regurgitation (DMR) are likely to require surgery, but years can pass until there is a clear indication for it. The timing of mitral valve surgery for asymptomatic patients with severe DMR is controversial, and current guidelines are limited because they are based on nonrandomized studies and expert opinion.
The main pathophysiological factor of chronic ischemic mitral regurgitation (MR) is the outward displacement of the papillary muscles (PMs) leading to leaflet tethering. For this reason, papillary muscle intervention (PMI) in combination with mitral ring annuloplasty (MRA) has recently been introduced into clinical practice to correct this displacement, and to reduce the recurrence of regurgitation.
Degenerative mitral valve disease involving anterior leaflet pathology is considered less favorable regarding durability of surgical repair than isolated posterior leaflet disease. We aimed to compare the outcomes of patients undergoing mitral valve repair for anterior, posterior and bileaflet pathologies, and to investigate predictors for repair failure.
Mitral regurgitation (MR) is one of the most frequent indications for valve surgery in developed countries, and echocardiographic assessment is an essential tool to evaluate its etiologies, severity, and therapeutic indications. The mitral valve apparatus is a complex structure composed of several parts: apart from the mitral valve leaflets and annulus, it also includes the chordae tendineae, papillary muscles, and left ventricular (LV) wall. MR can be caused not only by organic changes of the mitral valve ...
We sought to find the morphological mechanisms of recurrent mitral regurgitation (MR) after MitraClip procedure using 3D transoesophageal echocardiography (TOE).
Initial studies have suggested the familial clustering of mitral valve prolapse, but most of them were either community based among unselected individuals or applied non-specific diagnostic criteria. Therefore little is known about the familial distribution of mitral regurgitation in a referral-type population with a more severe mitral valve prolapse phenotype. The objective of this study was to evaluate the presence of familial mitral regurgitation in patients undergoing surgery for mitral valve prolapse, ...
Mitral valve disease becomes more prevalent as the population ages. As the number of percutaneous mitral valve interventions expands, obscure clinical scenarios may emerge and challenge conventional treatment algorithms. Strategies for dealing with complex repairs build on prior experience in mitral perivalvular leak repair. Cases using nitinol- and expanded polytetrafluoroethylene-based devices are used to treat mitral regurgitation in cases of focal mitral perforations and leaks between previously placed ...
MitraClip is the sole percutaneous device approved for functional mitral regurgitation (MR; FMR) but MR recurs in over one third of patients. As device-induced mechanical effects are a potential cause for MR recurrence, we tested the hypothesis that MitraClip increases leaflet stress and procedure-related strain in sub-valvular left ventricular (LV) myocardium in FMR associated with coronary disease (FMR-CAD).
Mitral valve repair (MVr) for severe, degenerative mitral regurgitation (MR) is the gold standard, as medical management carries poor prognosis. However, despite clear benefit of MVr, many eligible patients are untreated. This study investigated whether MVr restores patients to normal life expectancy, at any age of operation, by comparing long-term survival of post-MVr patients to the life expectancy of the general United States (U.S.) population.
Traditionally, physicians distinguished between mitral regurgitation (MR) as a determinant of outcomes and MR as a biomarker of left-ventricular (LV) dysfunction by designating the lesions as primary or secondary, respectively. In primary MR, leaflet abnormalities cause the MR, resulting in modest increases in LV end-diastolic volume over time, whereas in patients with classic secondary MR, LV dysfunction and dilatation lead to MR without structural leaflet abnormalities. However, certain patients with glob...
The indications for mitral valve surgery in patients with advanced non-ischemic dilated cardiomyopathy and functional mitral regurgitation are still unclear. We reviewed our experience of mitral valve surgery in such patients and explored factors that were predictive of outcomes. Fifty-three consecutive patients with non-ischemic dilated cardiomyopathy and an ejection fraction
This study evaluated outcomes of mitral valve surgery for severe ischemic mitral regurgitation (IMR).
Two randomized clinical trials of transcatheter edge-to-edge mitral valve repair in patients with secondary mitral regurgitation (the Multicentre Randomized Study of Percutaneous Mitral Valve Repair MitraClip Device in Patients With Severe Secondary Mitral Regurgitation [MITRA-FR] and the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation [COAPT]) report clinical outcome disparities that are largely unexplained. This appra...
Ischemic mitral regurgitation is a condition characterized by mitral insufficiency secondary to an ischemic left ventricular.Primarily, the pathology is the result of perturbation of normal regional left ventricular geometry combined with adverse remodeling.We present a comprehensive review of contemporary surgical, medical, and percutaneous treatment options for ischemic mitral regurgitation, rigorously examined by current guidelines and literature.
To review the efficacy of a minimally invasive surgical technique for mitral valve (MV) repair, we analyze a non-resectional technique for degenerative mitral regurgitation (DMR).
Williams syndrome is a genetic disorder associated with various cardiovascular abnormalities, most commonly supravalvar aortic stenosis and peripheral pulmonary stenosis. However, isolated severe mitral regurgitation necessitating surgical intervention is extremely rare. Here, we present the case of a 14-year-old child with Williams syndrome and isolated severe mitral regurgitation who underwent successful mitral valve repair.
Sinus of Valsalva aneurysm (SVA) protruding into the mitral anterior leaflet is an extremely rare clinical condition; herein, we present a case of unruptured noncoronary SVA protruding into the mitral anterior leaflet.
Left ventricular outflow tract obstruction (LVOTO) can be caused by multiple factors. One of rare causes of LVOTO is preserved anterior mitral valve leaflet and chordal apparatus after mitral valve replacement. Here, we describe a case of a patient who presented with worsening chronic congestive heart failure secondary to LVOTO from systolic anterior motion of residual native anterior mitral leaflet. This was surgically corrected by excision of anterior leaflet and chordal apparatus through the aortic root.
In certain pathologies, mitral valve repair is complicated by a paucity of tissue caused by fibrosis or destruction. Utilization of autologous pericardium for leaflet augmentation may be the only option to repair these valves. We present the midterm results of mitral valve leaflet augmentation with glutaraldehyde fixed autologous pericardium. 130 consecutive patients undergoing mitral valve repair with glutaraldehyde fixed pericardial augmentation of leaflets were followed up clinically and by echocardiogra...
