Relationship Between the Primary Entry Tear Locations and Surgical Outcomes of Acute Type A Aortic Dissection: A Single-Center Experience

The ascending aorta was the most frequent site of primary entry tear in acute TAAD. Although the differences in early outcomes did not reach statistical significance, the observed trends, including higher early mortality in the arch group and more frequent postoperative bleeding in the ascending aorta group, may reflect the influence of tear location. These findings should be further investigated in larger, multicenter studies.
