Noninvasive Cardiovascular Diagnosis of Patients With Fully Magnetically Levitated Blood Pumps
Sponsor: Thomas Schlöglhofer, PhD, MSc
Summary
Left Ventricular Assist Device (LVAD) therapy has become a well-established treatment option for endstage heart-failure either as a bridge to transplant (BTT) or destination therapy (DT). Monitoring of the pump and with this the cardiac status with the HeartMate 3 (HM3) is currently very limited to infrequent log-files with one data entry every 15 minutes and only limited amount of entries. Due to the low resolution data, the standard HM3 monitoring is not feasible for the evaluation of suction events or in depth analysis of the interaction between LVAD and the remaining native heart function. Aim of this study is to develop noninvasive diagnostics of the cardiac remaining respectively recovering function derived from HeartMate 3 pump data only and compare with standard clinical diagnostic procedures. These procedures include cardiac ultrasound and ECG. After this pilot study, the newly developed methods would allow frequent, simple and automatic monitoring of patients implanted with the HeartMate 3 device. Such continuous assessment of cardiac function would massively help therapy optimization of cardiac protection and, if possible, cardiac recovery.

Interventions
Routinely performed echo, ECG and hemodynamic monitoring
The pump data of patients on the ICU or normal ward are stored in a continuous data acquisition system (CDAS) on a notebook which is operated in battery operation, and analyzed afterwards with a mat-lab based software. For outpatients a mobile data-recorder will allow a continuous data acquisition for a period up to 2 months on a SD card. During this non-invasive pump data monitoring, routinely available hemodynamic monitoring, ECG and echo data will be collected.
