Intra-operative device closure of perimembranous ventricular septal defect without cardiopulmonary bypass under guidance of trans-epicardial echocardiography: a single center experience Yong Sun, Peng Zhu, Pengyu Zhou, Yilong Guo and Shao-Yi Zheng*
Abstract Background: Intraoperative device closure of perimembranous ventricular septal defect(VSD) through a lower mini-sternotomy is safe, less invasive, and has excellent surgical and cosmetic outcomes. Our study is to evaluate the feasibility of closing VSD under guidance of trans-epicardial echocardiography. Methods: We reviewed the clinical course of 41 patients referred to our institution for minimally invasive closure of perimembranous VSD. The trans-epicardial echocardiography(TEE) was used to monitor the whole procedure to guide the positioning of device and evaluate the operative effect instantly after operation. Result: The procedure was successfully done in 38 patients(92.6 %) with mean age of 1.2 ± 1.5 years(range 0.5-6. 1 years),mean weight of 10.78 ± 6.87 kg(range 5.2 ~ 26 kg) and VSD size of 5.1 ± 1.13 mm(range 5 ~ 10 mm). Three cases failed, including two cases whose guide-wires could not pass through VSDs and one case whose occluder could not repair VSD well. Three patients had tiny residual shunts because of the shifting of occluders. There were no major complications such as arrhythmia, valve regurgitation and the failure of occluder during follow-up(Mean 2.3 ± 1.2 years). TEE provided superior imaging of shapes and surrounding structures of the VSDs, and guide-wires passing through VSDs. Conclusions: Intraoperative device closure of perimembranous VSD through a lower mini-sternotomy without cardiopulmonary bypass appears to be a safe and effective procedure. The use of trans-epicardial echocardiography provides useful information for intraoperative device closure of VSD.

Background Perimembranous ventricular septal defect(VSD) is one of the most common congenital cardiac malformations. Closure of VSD is routinely performed with cardiopulmonary bypass,or interventional transcatheter occlusion i
