Echocardiography-Based Hemodynamic Monitoring Use on Inpatients Listed for Heart Transplantation Under 2018 Allocation Policy in United States

Abstract

Background: One notable change to the 2018 United Network for Organ Sharing listing criteria was to allow for the use of noninvasive hemodynamic monitoring for inpatients listed as status 3 for heart transplantation. We wanted to explore the feasibility of performing daily focused echocardiograms in place of invasive monitoring in this population. Methods: On retrospective chart review of inpatients listed for transplantation at our institution, 8 patients in the invasive monitoring group listed as status 1A (October 2016 to October 2018) and 9 patients in the echocardiographic group listed as status 3 (October 2018 to February 2020) were identified. Results: There were no significant differences between the 2 cohorts in the average measured/estimated right atrial, pulmonary artery systolic, and wedge pressures, although the echo cohort had lower cardiac index (P = .001). There were 2 patients with positive blood cultures treated with Swan exchange in Swan cohort and a total of 14 Swan exchanges. There were no infections in the noninvasive group. Conclusion: We present our experience with the use of noninvasive daily hemodynamic assessment using focused echocardiograms to manage patients undergoing heart transplantation listing as status 3 under the new United Network for Organ Sharing allocation system. This approach appears safe and feasible; however, it requires validation in larger cohorts.
