Applicability of the handmade ePTFE trileaflet-valved conduits for pulmonary valve reconstruction: An ex vivo and in vivo study

...The current study investigated: (i) the function of the ePTFE trileaflet-valved conduits in an ex vivo experimental system and (ii) the short-term performance of the conduit in a porcine model to verify their clinical applicability.... ... valves. 168 Right ventricular function was simulated by using a digitally controlled hydraulic piston 169 SuperPump (ViViTro Labs, Victor, British Columbia, Canada), which generated a pulsating 170 flow to drive the chamber and send it into a compliant pulmonary artery. ...
