The classic Maze procedure produces excellent results and remains the gold standard of therapy for patients with atrial fibrillation that is refractory to medical management However, several groups have recently reported that a complete lesion set may not be necessary for all patients and may be performed on a closed, beating heart using newer ablation technologies. The thoracoscopic "mini Maze" procedure, usually performed for paroxysmal atrial fibrillation, includes bilateral pulmonary vein isolation, ablation of the epicardial ganglion and excision of the left atrial appendage using small bilateral thoracotomies with thoracoscopic assistance. Between November 2005 and April 2007, we performed 20 mini Maze procedures at two institutions. Over a mean follow up of 23.5 months, 18 are in sinus rhythm. There was no mortality and no pacemaker placed. We conclude that the early experience with the mini Maze procedure is favorable.
