Abstract
- BACKGROUND: Minimally invasive surgery is currently popular, but this has been applied very sparingly to cardiac surgery because of some limitations. Our study evaluated the safety and efficacy of atrial septal defect (ASD) closure through a video-assisted mini-thoracotomy. MATERIAL AND METHOD: Fifteen patients were analyzed. Their mean age was 31+/-6 years. The mean ASD size was 24+/-5 mm and there were 3 cases of significant tricuspid regurgitation. The working window was made through the right 4th intercostal space via a 4~5 cm inframammary skin incision. CPB was conducted with performing peripheral cannulation. After cardioplegic arrest, the ASDs were closed with a patch (n=11) or direct sutures (n=4), and the procedures were assisted by using a thoracoscope. There were 3 cases of tricuspid repair and 1 case of mitral valve repair. The mean CPB time and aortic occlusion time were 160+/-47 and 70+/-26 minutes, respectively. RESULT: There was no mortality, but there were 3 minor complications (one pneumothorax, one wound dehiscence and one arrhythmia). The mean hospital stay was 5.9+/-1.8 days. The mean follow-up duration was 10.7+/-6.4 months. The follow-up echocardiogram noted no residual ASD or significant tricuspid regurgitation. Three patients suffered from pain or numbness. CONCLUSION: This study showed satisfactory clinical and cosmetic results. Although the operative time is still too long, more experience and specialized equipment would make this technique a good option for treating ASD.
