Abstract:
Objective To evaluate the mid-term safety, efficacy and feasibility of perventricular device closure for subarterial ventricular septal defect. Methods Clinical data of 97 patients diagnosed with subarterial ventricular septal defect through echocardiography in West China Hospital from September 2013 to December 2015 were retrospectively analyzed. There were 66 males and 31 females aged 3 (1.8, 5.9) years. All the patients underwent perventricular device closure under the guidance of transesophageal echocardiography using eccentric occlusion device. Possible complications such as residual shunt, valvular regurgitation, atrioventricular conduction block and arrhythmias were recorded during the 1-year, 3-year and 5-year follow-up. Results All the patients received perventricular device closure successfully except that 1 patient underwent open surgical repair under cardiopulmonary bypass 3 months later because of the migration of device. So the rate of complete closure was 99.0%. No residual shunt, moderate or severe valvular regurgitation, atrioventricular conduction block or arrhythmias were observed 5 years later. Conclusion Treating subarterial ventricular septal defect through perventricular device closure exhibits remarkable mid-term efficacy, safety and feasibility with high success rate.
