Active clinical trials for "Mitral Valve Insufficiency"

Improvement in heart failure with moderate to severe mitral regurgitation using a percutaneously delivered implantable device.

Comparison patients with CABG alone vs. CABG+mitral surgery with non-massive ischaemic mitral regurgitation (IMR) depending on stress echo data.

This multinational, non-interventional, investigator-initiated, retrospective study aims to investigate outcomes of patients, who underwent mitral valve transcatheter edge-to-edge repair (M-TEER) for primary mitral regurgitation (PMR).

Degenerative mitral insufficiency secondary to valve prolapse is the most common valve disease in Western countries. In the absence of specific treatment, it spontaneously progresses to heart failure and death when it is severe. Surgical mitral valve repair (or mitral plastic surgery) is the preferred treatment for primary mitral insufficiency by prolapse in case of severe leakage if associated with clinical and/or echocardiographic markers of poor prognosis (i.e., with high risk of morbi-mortality during their follow-up). It is therefore essential to refine the risk stratification of these patients in order to identify at-risk patients who should potentially benefit earlier from invasive care (cardiac surgery), or conversely, close monitoring. A number of echocardiographic and MRI parameters may have been associated with a poorer prognosis. A cohort of patients with primary mitral insufficiency (MI) will be followed to study the relationships of a set of factors to patient prognosis.

Observational study in adult humans undergoing surgical or cardiological intervention for mitral valve insufficiency. Investigators aim to evaluate hemodynamic changes on an arterial pressure waveform level in patients before and after mitral valve intervention using Nexfin (BMEYE, Amsterdam, the Netherlands) continuous non-invasive hemodynamic monitoring, using finger cuff based technology to register beat-to-beat data

This multinational, investigator-initiated, retrospective study aims to investigate outcomes of patients, who underwent transcatheter mitral valve implantation (TMVI), in comparison to those screened for TMVI but deemed ineligible, who subsequently underwent interventional mitral valve edge-to-edge repair, mitral valve surgery or medical/conservative therapy.

The 3D-PRIME study will analyse whether use of 3D echocardiography can improve risk stratification and cardiovascular outcome in patients with mitral regurgitation of different etiologies.

Paraprosthetic cardiac valve leaks are a progressive complication after after surgical or percutaneous heart valve replacement. These leaks can lead to heart failure and/or life-threatening hemolysis. Percutaneous closure of para-prosthetic leaks has been developed as an alternative to surgery in high-risk patients. These procedures remain technically challenging with a significant risk of failure and complications, but this risk is improved since the development of dedicated prostheses and the increased experience of the operators. The data in the literature concerning percutaneous leak closure remain limited and disparate and mostly retrospective.The impact of the procedures on the quality of life of patients is not known. Beyond the technical aspects and the follow-up of major cardiovascular events, investigators also wonder what is the impact of these procedures on the quality of life of patients. Investigators hypothesize that even a partial reduction in paraprosthetic leakage may be associated with an improvement in quality of life through reduction of transfusion needs and/or reduction of dyspnea. A prospective study is warranted to assess the technical and clinical and clinical results of these procedures, together with the evaluation of the the possible benefit on the quality of life of the patients.

This is a prospective Quality Improvement (QI) study using the Model for Improvement framework. The objective of this study is to implement a structured, comprehensive, innovative, and sustainable approach to the management of patients with advanced mitral valve (MV) disease and heart failure (HF) in Southeastern Ontario and to improve healthcare delivery, patient care, and patient outcomes in the context of structural surgical and percutaneous MV interventions. This will be achieved through the strategic implementation, promotion, and evaluation of: i.The first local Southeastern Ontario Structural Mitral Valve Clinic using an Interdisciplinary heart team (IHT) at the Kingston Health Sciences Centre (KHSC) and its integration with the KHSC's existing Heart Failure Clinic; ii.The first provincial Structural Mitral Valve Clinic electronic referral service on the Ontario electronic services platform; and iii.The promotion of the above through targeted KT (Knowledge Transfer) outreach activities. Patients for this study will be recruited through medical referral within the south eastern Ontario, Canada region.

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 the investigators will perform longitudinal follow-up data with cardiac MRI to inform the prophylactic surgery vs. close follow-up debate and to better define the natural history of this condition. The investigators hypothesize, that in the majority of patients mitral regurgitation will not worsen overtime, left ventricular hemodynamics will remain stable, exercise capacity will not decline, and symptoms will not worsen during follow-up. This finding would have a significant impact on the current recommendations for treatment in patients with mitral regurgitation by supporting a conservative management approach.
