Degenerative mitral regurgitation (MR) due to leaflet prolapse is frequent and can be surgically repaired in the vast majority of patients. Despite the efficacy of mitral valve repair, an ongoing international controversy exists regarding the need to perform early surgery in asymptomatic patients with severe MR and no sign of LV dysfunction in whom the probability of successful and durable repair is very high. In this group of patients, differing views of the risks of uncorrect...
The primary treatment for patients determined to have severe aortic or mitral regurgitation is surgical repair or replacement their valves. The most commonly used tool to quantify the severity mitral and aortic regurgitation is echocardiography. Studies have shown that echocardiography may have significant limitations in quantifying regurgitant volume. MRI has recently been shown to easily and reproducibly quantify regurgitation. To better understand how to accurately quantify ...
The main objective of this project is to determine intermediate-term echocardiographic outcomes in Medicare eligible patients (65 years of age and older) with moderate surgical risk who have undergone mitral valve surgery for degenerative mitral regurgitation.
Multicentre, double-armed, randomized controlled trial designed to compare mitral valve leaflet resection versus leaflet preservation with regards to the development of functional mitral stenosis following surgical repair of mitral valve prolapse. Patients will be randomized (1:1) to receive: (1) mitral valve repair with a leaflet resection or (2) mitral valve repair with leaflet preservation (using polytetrafluoroethylene neochordae), followed by echocardiographic and clinical...
Current American College of Cardiology/American Heart Association guidelines recommend that patients with severe degenerative mitral regurgitation be considered for mitral valve surgery. There remains a debate within the cardiology community regarding the appropriate management of patients who remain asymptomatic. In this study we will perform longitudinal follow-up data with cardiac MRI to inform the prophylactic surgery vs. close follow-up debate and to better define the natu...
To assess the safety and performance of the Cephea Transseptal Mitral Valve System for the treatment of symptomatic moderate to severe degenerative or functional mitral regurgitation, in patients who are poor candidates for surgery.
The purpose of this study is the evaluation of cardiac and pulmonary response to cardiopulmonary exercise in severe mitral regurgitation and its variation under treatment (surgical mitral valve repair, percutaneous mitral valve repair, optimal medical treatment). The study is conducted as a prospective, observational, single-center study. Patients suffering from symptomatic severe mitral regurgitation will be eligible, if they are referred to the University Hospital of Regensbu...
The preferred treatment of organic mitral regurgitation (MR) is mitral valve repair. Optimally this should be timed so late that it commensurate with the risk of surgery and before irreversibly damage of the heart and pulmonary vessels. The aim is to obtain an understanding of the differences between the symptomatic and asymptomatic patient. The study will test A: Symptomatic organic MR is characterized by higher filling pressure, and higher stroke work during physical ...
Effectiveness and Safety of Mitral Valve Repair With the NeoChord DS1000 Artificial Chordae Delivery System Versus Conventional Surgery in Patients With Severe Primary Mitral Regurgitation Due to Isolated Leaflet Prolapse
The main objective is to assess the effectiveness and safety of the NeoChord DS1000 repair technique as compared with conventional open-heart on-pump mitral valve surgery in patients with severe primary mitral regurgitation.
Prospective, observational, multi-center trial in which patients with mitral regurgitation sufficient to merit mitral valve repair will receive a surgical transvalvular, intra-annular Mitral Bridge™ to reduce or eliminate mitral regurgitation.
Early feasibility study, single-arm registry design
The study aims to analyze the role of left ventricular and left atrial functional parameters by speckle tracking echocardiography in predicting outcome after mitral valve replacement and targeting for early intervention compared to guideline parameters.
The goal of the study is to correlate the effect of ischemic mitral regurgitation on the outcome of STEMI patients treated with successful primary PCI using clinical data and echocardiography on presentation and during short term follow up after 3 months
Mitral valve regurgitation (leakage of the mitral valve of the heart) is frequent and currently there is no specific medical therapy. Mitral regurgitation is a slowly progressive disease that frequently requires surgical treatment. This randomized clinical trial will use Metoprolol, a common beta-blocker medication, to determine if medical treatment impacts mitral valve disease progression.
KALIOS is indicated for the surgical treatment of mitral regurgitation by mitral valve repair.It is intended for mitral valve repair using conventional open heart or minimally invasive techniques. The KALIOS device is an adjustable annuloplasty ring, to be implanted by open surgery, having a hollow structure that comprises a flat rigid ring surrounding a deformable cage. The unique feature of KALIOS is that its annular shape and dimension can be finely adjusted percutane...
A prospective, open-label, and multi-centered feasibility registry.
The study primarily aims to collect standard of care clinical data in a wide spectrum of simple to complex mitral valve regurgitation (MVR) cases to validate a post-processing stand-alone software prototype (QFlow), developed by Philips Research Paris (Medisys). Investigator does not intervene in the care of the patient, but simply collects standard of care images and measurements that are needed for the validation of the investigational software.
Recent publications show that an adjunctive subvalvular repair during mitral annuloplasty for secondary mitral regurgitation effective in preventing recurrent regurgitation. One of these procedures is the papillary muscles approximation. However, the safety and the positive impact of this method are still in doubt.
Comparison patients with CABG alone vs. CABG+mitral surgery with non-massive ischaemic mitral regurgitation (IMR) depending on stress echo data.
At present, the optimal treatment strategy for heart failure patients and moderate-to-severe (3+) or severe (4+) mitral regurgitation with a class IIa recommendation for CRT is uncertain.Whether these patents should also be treated for functional mitral regurgitation or with CRT also remains unclear. We therefore propose a randomized 2x2 factorial design in this patient population to understand the the impact of both CRT and transcatheter mitral valve repair with the MitraClip ...
The primary aim of this study is to assess the changes on the shape and function of the left ventricle in patients with severe mitral valve regurgitation due to congestive heart failure and cardiomyopathy who undergo mitral valve reconstruction with a Geoform ring. Three-dimensional echocardiogram will be used for precise evaluation of the shape and functino of the ventricle.
Background: - To evaluate the outcomes of mitral valve repair or replacement in patients with severe mitral valve leakage (regurgitation), researchers at the National Institutes of Health (NIH) will perform various tests to measure heart function before and after surgery. Objectives: - To record the results of echocardiograms and cardiopulmonary exercise testing in patients who are scheduled to have corrective surgery for severe mitral valve regurgitation. Eligi...
The objective of the study is to demonstrate the non-inferiority for clinical efficacy of an endovascular treatment strategy with the MitraClip® in comparison with a surgical treatment strategy in patients with severe primary mitral regurgitation judged eligible for anatomical repair with the MitraClip® or mitral valve surgery with high surgical risk. This trial is a French, multicenter and randomized trial. Patients enrolled will be clinically followed for 2 years ( clinica...
Background: The presence of a mild to moderate ischemic mitral regurgitation (IMR) results in a significantly reduced long-term survival and increased hospitalizations for heart-failure. The benefit of adding mitral valve surgery to coronary artery by-pass surgery (CABG) is well documented in the combination of coronary artery disease and severe MR. On the other hand, it is clinical practice to refrain from repairing the mitral valve in those CABG cases where the IMR is ...
The study evaluates the results of mitral valve repair with flexible band in comparison with rigid ring in patients undergoing mitral valve repair for degenerative mitral valve disease
