    Background: Transcatheter closure for atrial septal defect (ASD) with inferior-posterior rim deficiency has been scarcely reported with proper identification of the indications and limits. We aimed to assess the safety and feasibility of transcatheter closure of ASDs with deficient rims, paying particular attention to cases with inferior-posterior rim deficiency. Methods: From January 2008 to January 2013, 241 patients underwent transcatheter ASD closure, including 50 cases (20.7\%) with deficient rims, other than the anterior-superior one. Eighteen patients (12 females) presented inferior-posterior rim deficiency. Their median age was 8 (1.4-85) years and their median weight was 24 {[}9-97] kg. Transcatheter closure was performed in all cases under transesophageal echocardiography (TEE) guidance in children and intracardiac echocardiography (ICE) guidance in adults. Results: Out of 18 patients with inferior-posterior rim deficiency, only 8 underwent successful immediate transcatheter closure. Four cases failed to be closed. Major complications occurred in 6 patients, including 4 device embolizations, 1 pericardial effusion and 1 complete atrioventricular block that resolved after surgical removal of the device. During a median follow up of 54 +/- 13 months, a residual right-to-left shunt was documented in 2 more cases, requiring surgery in one case because of cyanosis. Transcatheter closure was successfully performed in the rest of the 223 patients, including in the 32 cases with deficient rims other than inferior-posterior. Conoluslons: Transcatheter closure of ASDs with inferior-posterior rim deficiency cannot be recommended.
