OBJECTIVE: To evaluate feasibility and outcome of minimally invasive video - assisted surgical closure atrial septal defect on beating heart without aortic cross-clamping techniques
METHODS: From 5/2013 to 5/2015, 52 patient had been ASD closure with video - assisted minimally invasive surgical methods via right submammary minithoracotomy. Cardiopulmonary bypass (CPB) was established via femoral artery, femoral veinous and right internal jugular vein. ASDs were closed with patches on beating heart, normothermia without aortic cross-clamping
RESULTS: 51 patients were successfully with the method, 1 case was opened more large incision to re-closured ASD, no patient required conversion to sternotomy. CPB mean time : 80 minutes; ventilated mean time: 4.5 hours. There had been no hospital mortality, no major complications. Follow-up (mean time 14 months): all patients are good, no late complications
CONCLUSIONS: Minimally invasive video - assisted surgical closure atrial septal defect on beating heart without aortic cross-clamping techniques are feasible and safe. Submammary incisions, periferal CPB were accepted and allowed for adequate surgical exposure and having a satisfactory cosmetic result
