Abstract:
Objective To evaluate the safety and efficacy of homemade patent ductus arteriosus (PDA) closure device for patients with very large PDA. Methods A total of 15 patients (12 females) with very large PDA, underwent transcatheter occlusion with homemade PDA devices. The median age was 21?8 (16-46) years old. The median diameter of the PDA at its narrowest point was 16?3 (13-22) mm. Aortic angiography and measurement of pulmonary pressure were performed before and after the closure of PDA. Repeat echocardiography was performed on each patient at one week, one month and six months after the procedure. Results Fifteen patients underwent transcatheter closure using a device of 23?4 (18-32)mm in diameter, and all of them showed a trace to small shunt by aortic angiography 30 minutes after the procedure. Thirteen patients was successfully occluded with a peak systolic pulmonary pressure decreased from 113?21 mm?Hg to 70?29 mm?Hg (P
