Extended Myectomy for Hypertrophic Obstructive Cardiomyopathy
Background The purpose of this study was to summarize our experience of extended ventricular septal myectomy in patients with hypertrophic obstructive cardiomyopathy (HOCM).Methods Thirty-eight patients (26 men,12 women) with HOCM underwent extended ventricular septal myectomy.The mean age was 36.3years (range,18-64 years).Diagnosis was made by echocardiography.The mean (mean ± SE) systolic gradient between the left ventricle (LV)and the aorta was 89.3 ± 31.1 mm Hg (range,50-184 mmHg) according to echocardiographic assessments before the operations.Moderate or severe systolic anterior motion (SAM) of the anterior leaflet of the mitral valve was found in 38 cases,and mitral regurgitation was present in 29 cases.Extended ventricular septal myectomy was performed in all 38 cases.The results of the surgical procedures were evaluated intraoperatively with transesophageal echocardiography (TEE) and with transthoracic echocardiography (TTE) at 1 to 2 weeks after the operation.All patients were followed up with TTE after their operation.
