Can a tiny sensor keep heart pump patients out of the hospital?
NCT ID NCT07096544
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a small wireless monitor in the lung artery can help people with a mechanical heart pump avoid hospital visits. About 40 adults who already have a HeartMate III heart pump will be randomly assigned to get the monitor or standard care. The goal is to see if the monitor helps doctors catch problems early and reduce heart-related hospital stays.
