Abstract:
Background: Atrial Septal Defect (ASD) is one of the most common congenital cardiac defects. Both surgical and catheter occlusion of the defect has been found effective and safe in eliminating interatrial shunting. However, knowledge of the response of the left side of the heart to ASD closure is incomplete. Objective: This study assessed the left side of the heart\u2019s response to ASD closure over a 6-month follow-up period. Subjects and method: 148 patients of ASD ostium secundum with an average age of 26.13 +/- 14.24 years (2-62 years) and the mean ASD size of 24.92 +/- 7.97 mm has been studied by echocardiography before and after atrial septal defect closure. Results: The right ventricular diameter and hemodynamics were improved after ASD closure (p<0.0001). The left ventricular end-diastolic diameter and volume increased significantly after ASD closure (p<0.0001). Conclusions: The left ventricular systolic function was unaffected by ASD closure. The right side of the heart\u2019s response to ASD closure over 6-month follow-up period decreased significantly (p<0.0001).
