Abstract

Residual or recurrent symptoms after septal reduction therapy are most often related to inadequate relief of left ventricular outflow gradients. We recently encountered a 71-year-old woman with hypertrophic cardiomyopathy and prior alcohol septal ablation who had a unique constellation of findings causing her symptoms. She was found to have four potential causes for her symptoms, residual midventricular obstruction, apical distribution of hypertrophy reducing end-diastolic volume, constrictive pericarditis, and marked arterial stiffness, as reflected by aortic atherosclerosis. She underwent complete pericardiectomy, transaortic septal myectomy, transapical myectomy, and replacement of a heavily calcified ascending aorta.
