title: Hypertrophic cardiomyopathy with apical aneurysm: left ventricular reconstruction and cryoablation for ventricular tachycardia.
abstract: This is a case study of a 58-year-old patient with hypertrophic cardiomyopathy, mid-ventricular obstruction, and apical aneurysm who had an episode of syncope due to ventricular tachycardia. Cardiovascular magnetic resonance imaging revealed asymmetrical left ventricular hypertrophy with mid-ventricular obstruction and an apical aneurysm. His coronary angiography was normal, and his ventricular tachycardia was induced by hypertrophic cardiomyopathy without ischemia. Apical aneurysmectomy, left ventricular reconstruction, and cryoablation at the rim of the aneurysm were performed. Fifteen days after the operation, an automatic implantable cardioverter-defibrillator was implanted. The postoperative course was uneventful, and ventricular tachyarrhythmia did not recur during 18 months of follow-up.
