The Aortic Root in Acute Type A Dissection: Repair or Replace? [1]
This single-center study of 299 patients operated on for type-A aortic dissection between 1992 and 2020 reported lower ten-year mortality (32 percent) after prosthetic or valve-sparing root replacement compared with ascending aorta replacement (52 percent; hazard ratio, 1.38; 95 percent CI, 1.12-1.68) without resecting the coronary sinuses, and lower proximal aorta reoperation rates (14 percent vs 23 percent; hazard ratio, 2.08; 95 percent CI, 1.44-5.56). The authors conclude that aortic root replacement should be considered when the aortic root is partially dissected or pathologically dilated.
