Abstract:
Objective To evaluate the effect of transcatheter closure of perimembranous ventricular septal defect (PMVSD) with symmetric ventricular septal occluder (SVSO). Methods Sixty-three patients with UCG confirmed PMVSD underwent transcatheter closure with SVSO. Results The implantation was successful in 58 patients (93.0%). The mean PMVSD diameter was 5.1?1.9 mm by angiography. The distance from the aortic valve to the rim of PMVSD was 2.7?1.0 mm and the mean size of SVSO was 7.2?2.1 mm. There was no residual shunt in 55 patients (94.8%) right after the deployment of SVSO. Arrhythmia was recorded in 15 patients (23.8%) during or after the procedure. New aortic regurgitation was observed in one patient after the implantation SVSO. Two patients developed myocardium injury and one patient developed obstruction of right ventricular outflow tract. Dislocation of the device was found in one patient. During the follow-up of 3 to 12 (means 7.4?2.7) months, no residual shunt, displacement or rupture of divices and endocarditis happened. Conclusion Transcatheter closure of PMVSD using SVSO is safe and effective, meanwhite attention should be paid to the complications such as arrhythmias.
