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

RV failure defined by the 2014 Interagency Registry for Mechanical Circulatory Support (INTERMACS)
The INTERMACS definition of RVF stratifies patients based on duration of inotropic therapy, inhaled nitric oxide therapy, vasodilator therapy or RVAD implantation. RVF is described as mild, moderate, severe, or severe acute based on ≤7, 8-14, \>14 days of the above therapies or RVAD implantation, respectively
Time frame: Through duration of hospitalization, up to 30 days following LVAD implantation
RV failure defined by the 2020 Academic Research Consortium (ARC)
