Abstract Objectives: To explore the feasibility and efficacy of electrophysiology guidance for transcatheter closure of perimembranous ventricular septal defect (PmVSD) in adults. Methods: Adult patients with PmVSD who underwent transcatheter in Guangdong Provincial People’s Hospital, Guangdong Cardiovascular Institute from February 2016 to January 2018 were selected. The distribution of the His-Purkinje system (HPS) close to the margins of PmVSD in the left ventricle was identified using three-dimensional (3D) electro-anatomic mapping and near-field HPS was further confirmed by different pacing protocols. The follow-up protocol included electrocardiogram (ECG)and transthoracic echocardiography at 6, 24, 72 h, 1, 3, 6… More >
