Key result
David operation linked to ~68-minute shorter hemostasis time vs. Bentall in type A dissection.
Why the study?
The clinical outcomes of the David operation versus the Bentall operation in patients with Stanford type A acute aortic dissection requiring aortic root replacement were compared focusing on hemostasis.

David operation may shorten hemostasis time in acute type A dissection; leaves open need for randomized trials before practice change.

Does the David operation reduce hemostasis time compared to the Bentall operation in patients with Stanford type A acute aortic dissection requiring aortic root replacement?
Absolute Event Rate: 144.6% vs 212.5%
p-value: p=0.047
The David operation is associated with shorter hemostasis and total operation times, as well as reduced blood transfusion requirements, compared to the Bentall operation in acute aortic dissection type A.
Ushioda et al. (2022) conducted a cohort in Stanford type A acute aortic dissection (AADA) requiring aortic root replacement (n=38). David operation vs. Bentall operation was evaluated on Hemostasis time (interval from cessation of cardiopulmonary bypass to the end of the operation) (p=0.047). The David operation resulted in a significantly shorter hemostasis time compared to the Bentall operation (144.6 vs. 212.5 minutes; p=0.047) in patients with acute aortic dissection type A.
