Why the study?
What are the three-dimensional velocity profiles in the ascending aorta in patients with normal versus artificial aortic valves?
What are the three-dimensional velocity profiles in the ascending aorta in patients with normal versus artificial aortic valves?
Intraoperative hot-film anemometry demonstrates that artificial aortic valves significantly alter the normal three-dimensional velocity profile of blood flow in the ascending aorta.
No takes yet. Share an insight, caveat, or question.
Artificial valves alter ascending aortic flow; leaves open whether these patterns affect outcomes or warrant design modifications.
Paulsen et al. (1988) studied this question.
