Commentary: Hypertrophic cardiomyopathy and the mitral valve—the debate continues

[摘要] In this edition of the Journal, Dearani and colleagues1 examine whether mitral valve (MV) leaflet length affects outcomes in patients with hypertrophic cardiomyopathy (HCM). In this retrospective study, MV leaflet lengths and coaptation length were measured by intraoperative transesophageal echocardiography (TEE) in 564 patients with HCM undergoing septal myectomy. The primary endpoint was relief of the left ventricular outflow tract (LVOT) gradient following myectomy, and secondary endpoints were reduction in the degree of mitral regurgitation (MR) and systolic anterior motion (SAM).
