A Multicenter Study Comparing Left Ventricular Unloading Methods During Veno-Arterial Extracorporeal Life Support in Patients with Cardiogenic Shock or Cardiac Arrest

What this Trial Is About

This international multicenter prospective observational study focuses on patients receiving veno-arterial extracorporeal life support (VA ECLS) for cardiogenic shock or cardiac arrest, conditions with very high hospital mortality rates. The research aims to understand left ventricular (LV) overload during VA ECLS and to describe and compare various LV unloading strategies in a large global patient group. The study also seeks to establish a shared definition of LV overload by collecting clinical, hemodynamic, and radiological data before and after unloading. Participants will undergo VA ECLS implantation as part of standard care for refractory cardiogenic shock or cardiac arrest. The study observes the use of different LV unloading techniques, collecting detailed information about when and how these strategies are applied. There are no additional interventions beyond the standard treatment necessary for patient care. During the study, researchers will gather demographic, clinical, instrumental, and laboratory data before and after VA ECLS implantation. They will monitor outcomes such as in-hospital mortality at 30 days and assess echocardiographic parameters related to LV overload and unloading effectiveness within 12 hours before and after the unloading technique. The study tracks patient progress to better understand the efficacy and impact of various LV unloading methods under real-world conditions.
