Abstract:
Objective To evaluate changes of RV volume and function in patients with ASD after transcatheter closure of ASD by three-dimensional echocardiography. Methods In 58 patients with ASD (24 men, 34 women; mean age 28.9?17.1, range 4 to 67 years), 23 patients (11 men, 12 women; mean age 25.7?13.3, range 6 to 57 years) were diagnosed as secundum ASD [the stretched diameters of ASD were from 9 to 36 (25.1?7.5) mm], and had successfully received Amplatzer septal occluder (ASO, the sizes of ASO ranged from 11 to 40 mm ). 32 healthy people (18 men, 14 women; mean age 24.8?12.0, range 4 to 45) were matched interms of age and sex as the control group. Three-dimensional images were acquired by HP-SONOS 5500 cardiac scanner (Hewlett-Packard Company, Andover, Mass) and were reconstructed by Tom-Tec EchoView 4.2 (TomTec Imaging Systems, GmbH) to calculate right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV) and right ventricular ejection fraction (RVEF). RVEDV, RVESV and RVEF were measured at 3 days, 1 and 3 months after the procedure. Results The RVEDV and RVESV [(101.74?25.17) mL vs (59.65?15.00) mL, P
