Objective To investigate clinical outcomes and safety of transesophageal echocardiography (TEE)-guided occlusion of infundibular ventricular septal defect (VSD) via minithoracotomy. Methods Clinical data of 21 pediatric patients with infundibular VSD who underwent TEE-guided occlusion via minithoracotomy in Children's Hospital of Hebei Province from January to June 2013 were retrospectively analyzed. There were 10 male and 11 female patients with their age of 8-24 (16±8) months and body weight of 9±3 kg. The size of VSD was 4.5±2.5 mm. TEE was used to evaluate the position of the occluder, its influence on the atrioventricular valves and aortic valve, and the presence of residual shunt. Results There was no perioperative death or complication. VSD occlusion was successfully performed in 20 out of 21 patients (95.2%). One patient received conversion to open VSD repair under extracorporeal circulation because VSD size was too big. Mean time of delivery of occluders was 32±16 minutes, the size of the occluders was 5±3 mm, and length of hospital stay was 6-8 days. All the patients were followed up for 3-6 months after discharge. During follow-up, echocardiography showed clear echo and normal position of the occluders, and there was no mild or more severe residual shunt or valvular regurgitation. Conclusion TEE-guided occlusion of infundibular VSD via minithoracotomy is easy to perform and safe with satisfactory clinical outcomes.
