Percutaneous Mitral Valve Repair. Percutaneous mitral valve repair (MVR) is a minimally invasive technique employed for treating mitral regurgitation (MR). The mitral valve is situated between the two left chambers (left atrium and left ventricle) of the heart.
Mitral regurgitation is a condition where the leaflets of the mitral valve do not completely seal when closed or are perforated (infection) resulting in blood returning to the left atrium. There is a classification of mitral regurgitation from mild, moderate, to severe.he mitral valve is located between the left upper and left lower chamber of the heart. Mitral valve regurgitation, or leaking, may be the result of a condition called mitral valve prolapse, in which the valve leaflets and the fibers, or cords, that support them become floppy and elongated.
