Assessing the immediate and sustained effectiveness of circular epicardial surgical ligation of the left atrial appendage
Journal of Cardiac Surgery, 04/24/2012
Adams C et al. – Epicardial suture ligation of the left atrial appendage resulted in successful intra–operative exclusion on TEE; however, a significant portion of patient's demonstrated communication of contrast on CT. This is suggestive of incomplete long–term exclusion. The clinical significance of reduction in left atrial appendage orifice area and volume with a persistent communication requires further study.
