Abstract
Background: There is a clinical need for additional remote tools to improve left ventricular assist device (LVAD) patient management. The aim of this pilot concept study was to assess the safety and feasibility of optimizing patient management with add-on remote hemodynamic monitoring using the CardioMEMS in LVAD patients during different treatment stages. Methods: Ten consecutive patients accepted and clinically ready for (semi-) elective HeartMate 3 LVAD surgery were included. All patients received a CardioMEMS to optimize filling pressure before surgery. Patients were categorized into those with normal mean pulmonary artery pressure (mPAP) (≤25 mmHg, n = 4) or elevated mPAP (>25 mmHg, n = 6), and compared to a historical cohort (n = 20). Endpoints were CardioMEMS device safety and a combined endpoint of all-cause mortality, acute kidney injury, renal replacement therapy and/or right ventricular failure at 1-year follow-up. Additionally, we investigated hospital-free survival and improvement in quality of life (QoL) and exercise tolerance. Results: No safety issues or signal interferences were observed. The combined endpoint occurred in 60% of historical controls, 0% in normal and 83% in elevated mPAP group. Post-discharge, the hospital-free survival was significantly better, and the QoL improved more in the normal compared to the elevated mPAP group. Conclusion: Remote hemodynamic monitoring in LVAD patients is safe and feasible with the CardioMEMS, which could be used to identify patients at elevated risk of complications as well as optimize patient management remotely during the out-patient phase with less frequent hospitalizations. Larger pivotal studies are warranted to test the hypothesis generated from this concept study.
