Assessment of Left Ventricular Function and Mitral Regurgitation Severity Early After Percutaneous Device Closure of the Atrial Septal Defect

Background: Atrial septal defect (ASD) is one the most prevalent forms of congenital heart disease in adults. Closure of ASDs eliminates left-to-right shunt and reduces right heart volumes, but the effects of ASD closure, on the left ventricle (LV) and mitral valve competence are somewhat inconsistent. Therefore, we designed this study to evaluate the early effect of percutaneous closure of ASD on LV function and mitral regurgitation (MR) severity. Methods: In this prospective study, we enrolled 32 patients with ASD secundum who underwent percutaneous device closure in Tehran Heart Center. We used transthoracic and transesophageal echocardiography (TEE) before the procedure and TTE 24 hours after the procedure, then compared obtained LV parameters before and after the procedure. Results: LV end-diastolic diameter (LVEDD) increased significantly from 44.8 ± 2.4 to 45.8 ± 2.8 (P
