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.
经皮腔内室间隔心肌消融术（PTSMA）已被广泛认可为肥厚性梗阻性心肌病（HOCM）患者的一种治疗选择。为了使PTSMA取得成功，我们需要探寻目标间隔动脉，包括任何为导致左心室流出道梗阻的肥厚间隔心肌供血的异常分支。本文介绍了一例通过优势右上间隔（RSS）动脉进行PTSMA的HOCM病例。在没有发自左前降支的有效间隔支动脉的情况下，应寻找RSS动脉作为PTSMA的替代途径。
