What is the best surgical treatment for obstructive hypertrophic cardiomyopathy and degenerative mitral regurgitation?

Background: Many prefer mitral valve replacement (MVR) for patients with obstructive hypertrophic cardiomyopathy (HCM) and concomitant degenerative mitral regurgitation (MR). We reviewed our results of septal myectomy combined with mitral valve repair (MVrep) and MVR when these problems coexist.

Methods: Between 1990 and 2006, 32 patients (56% men; mean age, 60.

Management of moderate functional mitral regurgitation at the time of aortic valve replacement: is concomitant mitral valve repair necessary?

Objective: The optimal management of moderate functional mitral regurgitation at the time of aortic valve replacement remains undefined.

Methods: We retrospectively identified 686 consecutive patients undergoing aortic valve replacement between 1993 and 2006 with at least moderate (grade 2 or more) functional mitral regurgitation. Patients with structural valve abnormalities or significant coronary artery disease were excluded, leaving 190 in the study.
