Hemodynamic Assessment of the Right Ventricle Using Pressure-volume Loop Catheter and Pulmonary Artery Catheter in Patients Undergoing Left Ventricular Assist Device Placement

University of Minnesota (UMN)

Status: Completed

Conditions: Right Ventricular Dysfunction

Treatments: Diagnostic Test: Hemodynamic assessment

Study type: Observational

Funder types: Other

Identifiers

NCT04478890

ANES-2020-28725

Details and patient eligibility

About

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.

Full description

This will be a prospective observational study design to characterize right ventricular function in 5 consecutive patients undergoing LVAD implantation at the University of Minnesota Medical Center (UMMC). Pre-, intra- and postoperative care delivery to all enrolled and consented patients will meet the standards of care otherwise delivered to patients undergoing LVAD implantation at UMMC; care delivery will be at the discretion of the clinical care team and will not be altered based on the output of the right ventricular high-fidelity conductance catheters.

Enrollment: 4 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients undergoing left ventricular assist device (LVAD) placement at the University of Minnesota Medical Center

Exclusion criteria

• Patients with a history of internal jugular vein thrombosis or known reasons for not being able to thread a central venous catheter through either internal jugular vein
• Patients with a history of known esophageal strictures, esophageal or stomach cancer, esophageal varices, or any patient in whom a TEE is contraindicated
• Patients with permanent pacemakers whose right ventricle is being paced and not in normal sinus rhythm
• Patients unable to consent to participating in the study
• Patients who are pregnant will be excluded, as part of standard care, all female patients are screened for pregnancy prior to surgery.
