The left atrial appendage (LAA) is the most frequent site of clot formation in patients with atrial fibrillation. The stroke rate in patient with atrial fibrillation is 12% per year at any age in clinical trial populations with a history of thromboembolism.1-3Go

Ligation of the LAA is commonly performed during cardiac surgery procedures.1Go Complete obliteration of the communication between the LAA and the body of the left atrium (LA) is mandatory to eliminate the potential for stagnant blood flow2Go but challenges the cardiac surgeon. Many studies reported incomplete closure of the LAA after surgical procedures, which may even increase the risk of embolization.4,5Go

This work describes our initial experience with a new simple surgical ligation of the LAA during cardiac surgery procedures. This technique enables "complete" obliteration of the LAA . . . [Full Text of this Article]
