NCT04478890

Brief Summary

This study will include the placement of a pressure volume (PV) loop catheter in the right atrium of patients undergoing left ventricular assist device (LVAD) placement and measure relevant PV loop data. Transesophageal echocardiography (TEE) and pulmonary artery (PA) catheter parameters as comparators to the PV loop will be recorded.
