Effects of the transcatheter closure of atrial septal defect on electrocardiographic and echocardiographic parameters six months after the closure

Abstract

Although percutaneous transcatheter atrial septal defect (ASD) closure (TCC) has been performed on adults for a long time there is limited data about the effects of the procedure in the literature and the majority of studies have been performed on children. The study purposed to evaluate the impact of TCC on cardiac remodeling, electrical changes and exercise capacity in adults. Transthoracic echocardiography and electrocardiography were performed one day before and six months after TCC in 27 consecutive patients who underwent successful TCC. Twenty-seven age and sex matched healthy subjects were used as control group. Right ventricular (RV) diameter (had decreased from 44±6.3 to 34±3.9; p [Med-Science 2017; 6(2.000): 213-6]
