Hemodynamic characterization of calcified stenotic human aortic valves before and after treatment with a novel aortic valve repair system.

Background And Aim Of The Study: The repair of calcified stenotic aortic valves may be a viable alternative to current valve treatments for early-stage aortic valve disease. To date, evaluation of valve repair feasibility on the benchtop has not been performed. A pulsatile flow system for testing intact human aortic valves was developed to perform quantitative hemodynamic and mechanical assessment of a new aortic valve repair approach.
