Abstract
Methods: Between 03/2004 and 04/2010, 52 patients underwent minimally invasive surgery for congenital ASD. Mean patient age was 40.79 ± 13.0 years, 34 (65.4%) were female. Indications for surgery were sinus venosus defect, shunt-volume >30% or ASD >2cm as well as persistent ASD after catheter based device-occlusion. Surgery was performed through a small right lateral mini-thoracotomy with cannulation of the peripheral vessels and video-assistance. ASD closure was conducted through the right atrium by either direct closure or pericardial patch. In the cohort, 2 (3.8%) patients suffered from a persistent foramen ovale, ASD II was present in 41 (78.8%) cases. A sinus venosus defect was found in 9 (17.3%) patients. All patients were in sinus rhythm preoperatively. Mean follow-up time was 42.3 ± 22 months. Perioperative parameters were analysed including stroke, arrhythmia, death and remaining ASD.
