Key result
Preoperative coronary malperfusion significantly increased the risk of early mortality (OR 5.3) in patients undergoing emergency surgery for iatrogenic Type A aortic dissection, a complication with a high overall mortality rate of 44.6%.
Why the study?
Iatrogenic aortic dissection is a rare, devastating complication in cardiac surgery and related procedures, and published data on emergency surgery following it are limited.
Cohort (n=92)
No
This paper presents a 23-year single-center experience detailing changes in patient characteristics, surgical approaches, and outcomes for iatrogenic Type A aortic dissection.

May inform evolving iatrogenic TAAD strategies; leaves open generalizability from single-center observational data.
Iatrogenic aortic dissection (IAD) is a rare but devastating complication in cardiac surgery and related procedures. Due to its rarity, published data on emergency surgery following IAD are limited. Herein, we discuss IAD occurring intra- and postoperatively, including those occurring during transcatheter aortic valve replacement and cardiac catheterization, and present benchmark data from our consecutive, single-center experience. We demonstrate changes in patient characteristics, surgical approaches, and outcomes over a 23-year period.

Aspern et al. (2022) conducted a cohort in Iatrogenic Type A aortic dissection (n=92). Preoperative coronary malperfusion vs. No preoperative coronary malperfusion was evaluated on Early mortality (OR 5.3, 95% CI 2.0-13.6, p=0.001). Preoperative coronary malperfusion significantly increased the risk of early mortality (OR 5.3) in patients undergoing emergency surgery for iatrogenic Type A aortic dissection, a complication with a high overall mortality rate of 44.6%.
