Transcatheter Closure of Atrial Septal Defect with a CardioSEAL Device

Abstract

SUMMARYTranscatheter closure of an interatrial septal defect (ASD) with a CardioSEAL device was successfully performed on 12 Taiwanese children. There were five boys and seven girls, aged from 3.6-13.9 (8.3 ± 3.2) years and with body weight of 15-57 (33.7 ± 14.7) kgs. After one year of follow-up studies, which included physical examination, ECG, chest X-ray and echocardiography, complete closure of ASD was achieved in nine (75%) patients. Two children with a trivial residual shunt were asymptomatic and without audible cardiac murmur. A girl had a small residual left to right atrial shunt by color Doppler echocardiography, but without audible cardiac murmur. There were no immediate or intermediate complications. Transcatheter implantation of the CardioSEAL device is a safe and proper treatment for children with non-complicated small to medium secundum ASD. (Jpn Heart J 2000; 41: 471-480)

Is interventional closure the current treatment of choice for selected patients with deficient atrial septation?

“…34 To a lesser degree, the more flexible devices, notably the CardioSEAL and STARflex, are used as alternatives in several centres. 13,21,22,35,36 A disadvantage of the latter devices is that they remain under trial in the United States of America. In smaller defects, those measuring less than 18 millimetres, comparison between the CardioSEAL/STARflex devices and the Amplatzer device has shown a low rate of complications in both, but shorter fluoroscopic and procedural times, as well as higher rates of complete occlusion, in the group of patients closed with the Amplatzer device.…”
