Experimental Study of Right Ventricular Hemodynamics After Tricuspid Valve Replacement Therapies to Treat Tricuspid Regurgitation

The increased understanding of right heart diseases has led to more aggressive interventions to manage functional tricuspid regurgitation (FTR)... ...In this study, a novel in vitro mock circulatory system that incorporated a realistic tricuspid valve apparatus in a patient-specific silicon right ventricle (RV) was designed and fabricated... ... A closed ventricular chamber housing the silicon RV model was connected to a closed atrial chamber at one end, and was directly connected to the pulsatile wave-generating piston pump (SuperPump AR series, ViVitro Labs Inc., Victoria, BC, Canada) at the other end to simu ...
