Ventricular vortex loss analysis due to various tricuspid valve repair techniques: an ex vivo study

The deteriorating nature of severe functional tricuspid regurgitation (FTR) has led to the heightened interest in this pathology... ...In this study, the hemodynamics of the right ventricle (RV) after (i) clover edge-to-edge tricuspid repair and (ii) double orifice tricuspid repair was evaluated in three right heart models using an ex vivo pulsatile platform emulating severe FTR with the aid of stereoscopic particle image velocimetry... … circulation (35). A closed ventricular chamber housing the silicon RV model was directly 184 connected to the pulsatile wave-generating piston pump (SuperPump AR series, ViVitro Labs 185 Inc., Victoria, BC, Canada) to …
