Filter by:Ischemic mitral regurgitation is a disease where the mitral valve is regurgitant, or leaking, as a result of changes in the muscle of the heart caused by coronary artery disease Ischemic mitral regurgitation, or IMR, is normally treated by repairing or replacing the mitral valve. Currently, we don't have very strong evidence showing which patients might benefit from mitral valve repair and which might benefit from replacement, and surgeons tend to repair or replace valves based on their preference or experience. Some surgeons, including Dr. Vincent Chan, the Principal Investigator, believe that the decision to repair or replace the valve should be based on specific measurements of the mitral valve. This study will randomly assign patients to receive either the current standard of care for ischemic mitral regurgitation, which is valve repair or replacement based on the surgeon's preference, or to have their treatment decided by a set of criteria called an algorithm. This algorithm will assign patients with certain mitral valve measurements to repair, and others to replacement. Patients will be followed for 12 months after surgery, to compare whether patients whose treatment was decided by the algorithm did better than patients whose treatment was decided by surgeon preference.
This study will evaluate the safety and functionality of the SAPIEN M3 System in patients with symptomatic, severe MR and will provide guidance for future clinical study designs utilizing the SAPIEN M3 System.
To assess the safety and effectiveness of the SAPIEN 3 transcatheter heart valve in patients with a failing mitral bioprosthetic valve.
The purpose of this study is to assess the safety, performance and clinical outcomes of the Edwards PASCAL Transcatheter Mitral Valve Repair (TMVr) System.
This study is a continuation of two previous studies --- the Severe Ischemic Mitral Regurgitation (SMR) Trial (NCT00807040) and the Moderate Ischemic Mitral regurgitation (MMR) Trial (NCT00806988) --- to learn more about patients' health 5-10 years after their mitral valve surgeries. The investigators will collect long-term health information on SMR and MMR trial participants using electronic medical records, patient and/or family input, public records, and healthcare- and vital status-related databases.
To evaluate the safety and performance of the Neovasc Tiara Mitral Transcatheter Heart Valve with the Tiara Transapical Delivery System.
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.
Aim of this prospective trial is to assess the hemodynamic effects of a MitraClip procedure caused iatrogenic arterial septal defect (iASD) and the functional changes after interventional iASD closure in a randomized setting.
Multicenter feasibility study of the HighLife™ TMVR system.
This is a multi-center, non-randomized, prospective Early Feasibility Study to evaluate the AccuCinch® Ventricular Restoration System in patients with symptomatic heart failure and concomitant functional mitral regurgitation that have stable symptoms on guideline-directed medical therapy
