Abstract/OtherAbstract:
Although percutaneous transluminal septal myocardial ablation (PTSMA) has been the established treatment of symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM), the efficacy for specific HOCM is not elucidated. We report a successful case of PTSMA for heart failure with severe left ventricular outflow tract (LVOT) obstruction due to sigmoid-shaped interventricular septum and diffuse left ventricular hypertrophy with Mönckeberg's arteriosclerosis and aortic valvular stenosis. While the PTSMA relieved LVOT obstruction and symptoms in the acute phase, the modest recurrence was confirmed 6 months later, which is rare in the case of idiopathic HOCM. The possible mechanisms of LVOT obstruction and recurrence are discussed.
