Key result
Bicuspid aortic valve morphology showed similar preoperative coagulation profiles to tricuspid valves, with no significant differences in ROTEM values except higher D-dimers in TAV patients.
Why the study?
The impact of aortic valve morphology on preoperative coagulation status in patients undergoing elective thoracic aortic surgery was unclear.
Does bicuspid aortic valve morphology affect preoperative coagulation status compared to tricuspid aortic valve in patients undergoing thoracic aortic surgery?

Does bicuspid aortic valve morphology affect preoperative coagulation status compared to tricuspid aortic valve in patients undergoing thoracic aortic surgery?
Patients with a bicuspid aortic valve undergoing thoracic aortic surgery have similar preoperative coagulation profiles to those with a tricuspid aortic valve, indicating no need for altered coagulation management.
Comparable preoperative coagulation profiles in BAV and TAV patients should not alter management; leaves open effects on bleeding risk in aortic surgery.

Haeren et al. (2025) conducted an observational in Elective thoracic aortic surgery (n=169). Bicuspid aortic valve (BAV) vs. Tricuspid aortic valve (TAV) was evaluated on Preoperative coagulation status (ROTEM and conventional coagulation tests). Bicuspid aortic valve morphology showed similar preoperative coagulation profiles to tricuspid valves, with no significant differences in ROTEM values except higher D-dimers in TAV patients.
