Filter by:The purpose of the study is to demonstrate the long term safety and effectiveness of the Carpentier-Edwards® PERIMOUNT Magna Mitral Valves in patients undergoing mitral valve replacement with or without concomitant procedures requiring cardiopulmonary bypass.
The device is a dynamic annuloplasty ring/band that is able to be adjusted in order to correct for mitral regurgitation intraoperatively or postoperatively, off-pump.
Improvement in heart failure with moderate to severe mitral regurgitation using a percutaneously delivered implantable device residing in the coronary sinus
People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the valve. The best way to fix the mitral valve remains undetermined. This study will evaluate whether it is better for people with severe mitral valve leakage to undergo a mitral valve replacement procedure or a mitral valve repair procedure.
Coronary artery bypass grafting (CABG) is a procedure that people with coronary artery disease (CAD) may undergo to increase blood flow to the heart. During a CABG procedure, people who have a leak in one of the valves in the heart—the mitral valve—may at the same time undergo a procedure that repairs the valve. This study will evaluate whether people with moderate mitral valve leakage would be better off undergoing CABG plus the mitral valve repair procedure or undergoing CABG alone.
Prospective single-arm study of the AccuCinch® Ventriculoplasty System in the treatment of mitral valve regurgitation through subvalvular mitral repair. Purpose: To demonstrate the safety, feasibility and potential efficacy of using the AccuCinch® Ventriculoplasty System to reduce mitral valve regurgitation through subvalvular mitral repair.
Improvement in heart failure with moderate to severe mitral regurgitation using a percutaneously delivered implantable device.
Left ventricular (LV) remodeling after acute myocardial infarction (AMI) has been well described in previous studies. However, there is a paucity of data on the incidence of and risk factors for LV remodeling in modern clinical practice that incorporates widespread use of acute reperfusion strategies and almost systematic use of "antiremodeling" medications, such as angiotensin-converting enzyme inhibitors and beta blockers. The recent improvements in AMI management do not abolish LV remodeling, which remains a relatively frequent event after an initial anterior wall AMI. As a leading cause of heart failure, postinfarction LV remodeling represents an important target for therapeutic interventions. Within the ventricular mass, size, shape, connections and orientation in a three-dimensional space of every single constituent determine its functional behavior. The complex architecture of the ventricular mass creates multiple inhomogeneities of electrical and mechanical loads at the cellular and the microscopic tissue level, that cause cardiac function to be 'stochastic in nature'. The myocardial infarction will altered the ventricular shape and functional inhomogeneities carrying the morphodynamic advantages such as impaired suction for diastole after diminishing recoil relaxation with decreased twisting strain in systole. The alteration in contractile mechanics interacts with the intraventricular fluid dynamic filed that influence the regional myocardial shearing stress. Altered LV transmural wall strains have been proposed to cause infarct extension and may have an important role in propagating LV remodeling.
This clinical study is a multicenter, prospective non-randomized observational study without concurrent or matched controls in which 150 patients receiving an SJM® Rigid Saddle Ring will be included. The primary objective of the study is to demonstrate the effectiveness of the SJM® Rigid Saddle Ring when used in mitral valve repair procedures.
This proposal puts forward a research plan to initiate a genetic databank, henceforth referred to as The Genebank at Scripps Clinic Registry. This database will usher in genomic research at Scripps as we strive to stay at the forefront of cardiovascular research in the new century. Human subject donation allows for the creation of the proposed genebank.
