Late occurrence of ventricular septal rupture after deep septal myectomy for hypertrophic cardiomyopathy: Causes and management.

ABSTRACT: Surgical septal myectomy is increasingly utilized for patients with hypertrophic obstructive cardiomyopathy who remain symptomatic despite maximum doses of medical therapy. Deep and extensive septal muscle resections may lead to iatrogenic ventricular septal defects that are detected on transesophageal echocardiography immediately after weaning from cardiopulmonary bypass and immediately corrected in the same surgery. However markedly thinned out ventricular septum after myectomy may be prone to late rupture from high left ventricular systolic pressures causing delayed detection of a ventricular septal defect when the patients present with new onset symptoms. Additionally, a surgical injury to the first septal perforator artery during the myocardial resection leading to septal infarction m
