Clinical Trial Summary

This project evaluates right ventricle (RV) protective strategies after left ventricular assist device (LVAD) implantation.

Description:

The main purpose of this study is to learn more about protecting against RV dysfunction and RV failure (RVF) in patients receiving LVAD implantations. This is a prospective, randomized controlled study that will include 20 patients with heart failure undergoing LVAD implantation. Patients will receive their LVAD implantation as part of routine care. Patients will be randomized 1:1 to one of two arms, 1) standardized RV management arm, and 2) usual care RV management arm, which are both consistent with standard of care (SOC).
