Abstract:
Objective To investigate the feasibility and safety of surgical device closure of doubly committed sub-arterial ventricular septal defect via left sub-axillary.Methods A total of 45 patients diagnosed as doubly committed sub-arterial ventricular septal defect (dcVSD) with transthoracic echocardiography (TTE) and transesophageal echocardiography(TEE) were enrolled from June 2014 to August 2016 in Henan Children Heart Center,Henan Provincial People's Hospital.There were 39 males and 6 females,with the mean age of (2.2 ±2.1) years old(0.5-8.0 years),the body weight (13.8 ± 7.1) kg(7.0-34.1 kg),the defect size (4.5 ± 1.0) mm (3.0-8.0 mm).After general anesthesia,the patients were in supine and evaluated by TEE which indicated whether they were fit to closure.Then,they were turned to the right lateral position while this technique was determined.A vertical incision of 2-3 cm was made between the third and the fifth intercostal space and invasion in thoracic space via fourth intercostal space.Puncture was done at the anterior surface of right ventricular outlet tract to build a delivery tract.The occluder was released and the VSD was occluded under transesophageal echocardiography guidance.Results Forty-one patients had a successful surgical dcVSD closure with asymmetric occluders sized (6.0 ± 1.5) mm(4-10 mm).Among 4 failure cases,2 cases (4.4％) were switched to open-heart surgical repair,1 case (2.2％) due to device related aortic regurgitation,the rest 1 case (2.2％) experienced a dislocation of occluder into pulmonary artery and was converted to surgical repair after retrieve of occluder.Trivial residual shunt was detected in 2 cases (4.4％) postoperatively,a spontaneous closure was observed by 1 month follow-up and 3 months follow-ups,respectively.All the patients were discharged 5 to 8 days after the operation.With a follow-up of (10.4 ±5.0) months [3-24 months],there were no complications such as pericardial effusion,displacement of device,atrioventricular block or new valvular dysfunction.Conclusions Minimally invasive device closure of doubly committed sub-arterial ventricular septal defect via left sub-axillary is a feasible and safe treatment for closure of dcVSD.This technique has advantages of minor wound,less exudation,covert incision,however,long term follow-up is necessary.
