Clover repair offers a surgical solution that can be applied for the treatment of primary and secondary Tricuspid regurgitation (TR). Flow was provided by a pulsatile pump system (ViVitro Labs Inc., Victoria, BC, Canada), which was coupled to the right ventricle through a third connector. This new clover technique was demonstrated to successfully reduce TR in an ex vivo porcine heart model.

Minimally invasive mitral valve surgery (MIMVS) and transcatheter edge-to-edge repair (TEER) are complex procedures used to treat mitral valve (MV) pathologies, but with limited training opportunities available. The SuperPump, a pulsatile cardiac piston pump in combination with a viscoelastic impedance adapter (both ViVitro Labs, Inc., BC, Canada), is attached to the LV and produces preselected and customizable waveforms at various frequencies and amplitudes. Ex-vivo modelling of MV pathologies and repair procedures using the described simulator realistically replicated physiological in-vivo conditions.

The aim of this study was to evaluate and compare a novel open aortic annuloplasty ring (the A-ring) with the Dacron ring. The ventricular chamber was coupled to a digitally controlled piston pump (SuperPump AR Series, ViVitro Labs, Victoria, Canada), delivering a pulsatile flow to simulate left ventricular ejection into the aortic root. Overall, the echographic data revealed that both interventions had a downsizing effect on the aortic root, while still maintaining the distensibility comparable to the native condition.
