The risk of late-onset atrial fibrillation after surgical aortic valve replacement is only 4%, according to a study by Thoralf M. Sundt, MD, Chin Siang Ong, MBBS, PhD, and colleagues. Prophylactic tissue ablation or ligation/amputation of the left atrial appendage may not be warranted at the time of surgery.
Chin Siang Ong, MBBS, PhD, is a research fellow in the Division of Cardiac Surgery at Massachusetts General Hospital.
