Introduction
Left ventricular outflow tract (LVOT) obstruction is a recognized complication1 associated with hypertrophic cardiomyopathy that causes symptoms such as dyspnea on exertion and syncope. Medical treatment is often unable to relieve the symptoms of hypertrophic obstructive cardiomyopathy (HOCM), and surgical treatment with septal myectomy has become the gold standard for such patients(1). Percutaneous transluminal septal myocardial ablation (PTSMA) has emerged as an alternative and has become an established treatment for symptomatic patients with HOCM.
Herein, we describe urgent PTSMA for exacerbated LVOT obstruction after surgical aortic valvular replacement (AVR) in an elderly woman.
