Abstract
Patients with hypertrophic cardiomyopathy (HC) who require surgical treatment are usually severely symptomatic, with a high left ventricular (LV) outflow tract gradient and a high LV end-diastolic pressure. 1 For the last 25 years, the surgical procedure of choice for the patients has been septal myotomy and myomectomy. 2,3 Previous studies, 1–4 in a small group of patients with HC, have shown that mitral valve replacement, alone or combined with myomectomy, also offers improvement of the New York Heart Association functional class and the LV outflow tract gradient. We report the degree of hemodynamic and symptomatic improvement in such patients early and late after mitral valve replacement.
