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.
