Does combined anterior mitral leaflet extension and myectomy improve functional status and reduce outflow tract obstruction in patients with HOCM?
Combined anterior mitral leaflet extension and myectomy provides sustained functional and hemodynamic improvements in patients with hypertrophic obstructive cardiomyopathy.
Long-term follow-up shows sustained improvement in functional status, reduction of outflow tract obstruction, and attenuation of mitral regurgitation and systolic anterior motion of the mitral valve. In this respect, the new technique widens the surgical applications in HOCM.
Lee et al. (Tue,) studied this question.
