Transapical septal myectomy can be performed for patients with nonobstructive hypertrophic cardiomyopathy and diastolic dysfunction to enlarge the LV cavity. The procedure may also include limited shaving of severely hypertrophied papillary muscles. This report illustrates the usefulness of papillary muscle resection to enlarge the left ventricle in a patient with nonobstructive hypertrophic cardiomyopathy and preexisting mitral valve prosthesis.

Abstract Background Obesity is highly prevalent in patients with obstructive hypertrophic cardiomyopathy (HCM). In this study, we investigated the impact of body mass index (BMI) in patients undergoing septal myectomy (SM) for obstructive HCM. Methods We reviewed 2,746 patients who underwent transaortic SM for obstructive HCM from February 1993 through September 2018. Patients were stratified into 3 groups based on BMI (normal weight Results Preoperatively, median left ventricular outflow tract ...

Abstract Background Midventricular obstruction (MVO) is an uncommon variant of hypertrophic cardiomyopathy (HCM). In patients receiving septal myectomy for HCM, failure to recognize the concurrent MVO in the context of basal septum thickening can lead to inadequate excision and residual gradient. In this report, we detail the operative outcomes of MVO with and without coexistent basal septal hypertrophy. Methods From February 1997 through September 2018, 196 patients underwent midventricular mye...
