From: Phase contrast 4D flow in bicuspid aortic valves in a porcine model
Preoperative streamline analysis of pig 1 with a normal tricuspid aortic valve in systole (a) and early diastole (b). In (a) laminar flow is shown in the ascending aorta, the aortic arch and the proximal descending aorta. No helical or vortical flow is present. In (b) laminar flow is still present in the proximal descending aorta in (black arrows).
