Abstract:
Hypertrophic obstructive cardiomyopathy (HOCM) is a relatively common hereditary cardiomyopathy, which is featured by asymmetric myocardial hypertrophy and dynamic left ventricular outflow tract (LVOT) obstruction. Other than septal hypertrophy, mitral valve abnormalities are also quite common in HOCM patients, and they also contribute to systolic anterior motion of the mitral leaflets and LVOT obstruction. Septal myectomy is believed as the standard surgical treatment for HOCM, but whether to perform mitral valve procedures at the same time of myectomy is still debatable. In this article, we thoroughly explained the mitral valve abnormalities in HOCM patients and their surgical corrections. Besides, we also explained the controversies over mitral valve procedures based on the current clinical studies.
