[Feasibility of retrograde approach for percutaneous closure of ventricular septal defect under solely guidance of transesophageal echocardiography].

ABSTRACT

OBJECTIVE: To evaluate the feasibility of retrograde transcatheter closure of ventricular septal defects (VSD) under trans-esophageal echocardiography (TEE). METHODS: Twelve patients with VSD, with 4 residual shunt, treated by transcatheter VSD closure under solely guidance of TEE were summarized. Mean age, body weight and average diameter of VSD in 12 cases were (11.58±6.57) years, (31.85±13.28) kg, (5.50±2.20) mm, respectively. All patients were treated by retrograde transcatheter closure under solely guidance of TEE. The post-operative efficiency was estimated by TEE immediately. Patients were followed up by echocardiography, X-ray examination and electrocardiogram at 24 hours, 1, 3 and 6 months after the procedures. RESULTS: All 12 patients were treated successfully under solely guidance of TEE. The diameter of devices were 5-14 mm. There were 1 case with trivial residual shunt after the procedures immediately. No patients suffered from residual shunt, occluder malposition, peripheral vascular injury and pericardial effusion during the follow-up. CONCLUSION: Percutaneous transcatheter closure of VSD completely guided by TEE is safe and effective. This method could avoid the radiation and contrast media reaction, and also could simplify the procedure.
