A successful case of percutaneous transluminal septal myocardial ablation for left ventricular outflow tract obstruction caused by sigmoid septum
Journal of Cardiology Cases(2020)
摘要
A sigmoid septum is a state of angulation between the basal interventricular septum and the ascending aorta. Although considered to have no clinical importance, it may cause left ventricular outflow tract obstruction (LVOTO) in a hypercontractile state. Percutaneous transluminal septal myocardial ablation (PTSMA) is a catheter-based therapy aimed at improving drug-refractory symptoms in patients with hypertrophic obstructive cardiomyopathy. Few studies have reported the use of PTSMA for patients with LVOTO caused by sigmoid septum.
