Why the study?
Does the use of pericardial aortic valve prostheses reduce turbulent stresses compared to porcine aortic valve prostheses in pigs?
Does the use of pericardial aortic valve prostheses reduce turbulent stresses compared to porcine aortic valve prostheses in pigs?
Pericardial aortic valves demonstrate superior acute hemodynamics with lower turbulent stresses compared to porcine valves in a porcine model.

Pericardial valves may reduce acute turbulent stress versus porcine in aortic positions; animal data leaves open human translation and durability.
