Abstract
The present study investigated the feasibility of totally transthoracic echocardiography-guided percutaneous device occlusion of atrial septal defects (ASDs) without using x-ray equipment.Between September and December 2014, we performed totally transthoracic echocardiography-guided percutaneous device occlusion for 20 patients with secundum ASD without using x-ray equipment. We carried out percutaneous femoral vein puncture, used a specialized delivery sheath during operation, and closed the ASD by releasing an occluder.All 20 patients experienced successful occlusion and smoothly went through the perioperative period. The average procedure time ranged from 30 to 40 minutes (32.4 ± 3.5 minutes), and the size of the implanted occluder ranged from 20 to 38 mm (25.4 ± 5.8 mm). No occluder displacements, residual fistula, or thrombus-related complications after the procedure. There was no clinical death, no arrhythmia, no hemolysis, no infection, or embolism during patients’ hospitalization and the follow-up period.Totally transthoracic echocardiography-guided percutaneous device occlusion of ASDs without the use of x-ray equipment may be safe and feasible.
