Filter by:The purpose of this study is to assess the role of cardiac imaging combined with demographic, clinical, and biochemical parameters in predicting outcomes following percutaneous mitral valve intervention in order to facilitate more careful risk stratification, interventional planning and avoidance of high risk futile procedures.The principle objective of this study is to determine if transthoracic echocardiography (TTE) can predict changes in left ventricular (LV) size and function following percutaneous mitral valve intervention (PMVI).
This study will establish the safety and effectiveness of the SAPIEN M3 System in subjects with symptomatic, at least 3+ mitral regurgitation (MR) for whom commercially available surgical or transcatheter treatment options are deemed unsuitable. Following completion of enrollment, subjects will be eligible for enrollment in the continued access phase of the trial.
To evaluate the feasibility and safety of the Millipede Transcatheter Annuloplasty Ring System in subjects with functional mitral regurgitation
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
Early feasibility study, single-arm registry design
The main objective is to assess the effectiveness and safety of the MitralStitch repair system in patients with moderate to severe and severe mitral regurgitation.
This longitudinal cohort study evaluates the relationship of myocardial tissue markers characteristics assessed by cardiac MRI, with clinical measures of symptoms and functions in adults with primary mitral regurgitation. Participants are followed conservatively or may choose to undergo surgical repair at the discretion of their clinical team.
The main objective is to assess the effectiveness and safety of the MitralStitch repair system in patients with moderate to severe and severe mitral regurgitation.
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.
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 severity of regurgitation the investigators propose this study with the following aims: 1) compare MRI to echocardiography in the evaluation of regurgitant volume in patients with aortic or mitral regurgitation and 2) to assess which technique is better at predicting the response of the left ventricle to valve surgery.
