Long-term Clinical and Echocardiographic Follow-up After Surgical Correction of Hypertrophic Obstructive Cardiomyopathy With Extended Myectomy and Reconstruction of the Subvalvular Mitral Apparatus

Abstract

Extended myectomy and reconstruction of the subvalvular mitral apparatus in HOCM result in excellent functional improvement with relief of outflow tract obstruction. The technique can be performed safely despite its more aggressive surgical nature and allows an individualized strategy depending on the patient's extent and distribution of left ventricular hypertrophy.
