Heart remodeling in children after endovascular and surgical repair of atrial septal defect

The study of indices of heart remodeling was performed in children with secondary atrial septal defects (ASDs) after either endovascular or surgical repair of the defects. Data analysis showed that serious ASDs lead to diastolic left ventricular (LV) dysfunction. Recovery of LV function occurred during the first day following endovascular repair or after six months following surgical correction. Maximum reduction of dilatation of the right heart chambers after of ASD repair is recorded in the early postoperative period and keeps during follow-up, regardless of the method of defect repair. We found a significant depression in mechanical activity of left atrium after surgical repair with the recovery one year after the procedure.
