Comparison of the Sideris and Amplatzer Septal Occlusion devices

The results of transcatheter atrial septal defect (ASD) occlusion with 2 di fferent devices (Sideris adjustable buttoned device vs Amplatzer Septal Occ luder) were compared in 2 consecutive series of patients. Comparative outco mes were assessed by whether a device was implanted or not, by complication s and fluoroscopy time of implantation, and by the incidence of residual sh unting on transthoracic echocardiography at follow-up. The patient and defe ct characteristics were similar in both groups. Twenty-eight of 33 Sideris devices and 37 of 39 Amplatzer devices were implanted, The fluoroscopy time for the Amplatzer implants was 13.4 minutes (range 8 to 41) compared with 23.7 minutes (range 11 to 60.6) for the Sideris implants (p <0.001). The co mplete occlusion rate for the Amplatzer device was 93% compared with 44% fo r the Sideris device at 1 year (p <0.001), In conclusion, the Amplatzer dev ice produces higher occlusion rates of ASDs with shorter fluoroscopy times, (C) 1999 by Excerpta Medico, Inc.
