Mitral Valve Replacement and Limited Myectomy for Hypertrophic Obstructive Cardiomyopathy: A 25-Year Follow-Up

RESUMO

Hypertrophic obstructive cardiomyopathy is a dynamic obstruction of the left ventricular outflow tract caused by septal hypertrophy and systolic anterior motion of the mitral valve. When the condition cannot be controlled by medical therapy, the most frequently used surgical approach is left ventricular myotomy-myectomy. Mitral valve replacement (to correct another mechanism of obstruction) is another surgical option; however, its use for this condition is controversial. We review the long-term results of patients who underwent limited left ventricular myotomy-myectomy and mitral valve replacement at our institution.
