Abstract
Despite its proven efficacy, the left atrial lesion set of the Cox-maze III operation is not universally employed during coronary artery bypass or aortic valve surgery for patients with atrial fibrillation, in part due to the surgeon's reluctance to add bicaval cannulation and a left atriotomy not needed for the primary procedure.

Background/Introduction Despite its proven efficacy, the left atrial lesion set of the Cox-maze III operation is not universally employed during coronary artery bypass or aortic valve surgery for patients with atrial fibrillation, in part due to the surgeon’s reluctance to add bicaval cannulation and a left atriotomy not needed for the primary procedure
Discussion/Conclusion The amputated left atrial appendage stump can be used as a window to create a full pulmonary vein box lesion set and connecting lesion to the annulus of the mitral valve
This simplified technique could allow more wide spread use of the left atrial Cox-maze III lesion set in concomitant atrial fibrillation ablation procedures
Summary
Background/Introduction Despite its proven efficacy, the left atrial lesion set of the Cox-maze III operation is not universally employed during coronary artery bypass or aortic valve surgery for patients with atrial fibrillation, in part due to the surgeon’s reluctance to add bicaval cannulation and a left atriotomy not needed for the primary procedure. David H Savage From World Society of Cardiothoracic Surgeons 25th Anniversary Congress, Edinburgh Edinburgh, UK. Aims/Objectives To describe a less invasive technique to create a complete lesion set encircling all pulmonary veins and a connecting lesion to the mitral annulus that does not require bicaval cannulation or an atriotomy in addition to amputation of the left atrial appendage.
