title: Successful percutaneous transluminal septal myocardial ablation through a right superior septal artery for a patient with hypertrophic obstructive cardiomyopathy.
abstract: Percutaneous transluminal septal myocardial ablation (PTSMA) has been widely accepted as a therapeutic option for patients with hypertrophic obstructive cardiomyopathy (HOCM). To achieve success in PTSMA, we need to explore the target septal arteries, including any anomalous branches that feed the hypertrophic septal myocardium causing left ventricular outflow tract obstruction. An HOCM case in which PTSMA was performed through a dominant right superior septal (RSS) artery is presented. In cases without an effective septal branch artery arising from the left anterior descending artery, an RSS artery should be sought as an alternative route for PTSMA.
