Dynamics Mechanical Strains of Tricuspid Valve Septal Leaflets

...study to establish a framework for the measurement of the deformation of TV leaflets in a passive ex-vivo beating heart that mimicked the right ventricular dynamic pressure of the normal hearts. ...apexes of fresh porcine hearts (n= 8) were connected to a positive displacement pump (SuperPump AR Series, Vivitro Labs Inc., BC) to generate pulsatile flow in the right side of the hearts. The superior vena cava was connected to a reservoir as the inflow pathway and the pulmonary artery was used for the outflow pathway...
