Methods
We prospectively examined 22 consecutive patients who underwent percutaneous transcatheter closure of secundum ASD from June 2013 to December 2014. Echocardiography was initially performed upon admission, prior to cardiac catheterization and then 1 month after percutaneous closure of secundum ASD. Pulsed TDI was obtained from the basal right ventricular (RV) free-wall tricuspid annular junction in the apical 4-chamber view. The measurements that were performed from the TDI recording in each of the 3 sites included: peak early diastolic myocardial tissue velocity (E’), peak late diastolic myocardial tissue velocity (A’), E’/A’ ratio, and peak systolic myocardial tissue velocity (s). All measurements were made in 3 consecutive cardiac cycles, and the average was calculated for subsequent analysis.
