3D Imaging Study of Right Heart Function During Mechanical Pump Placement for Heart Failure

What this Trial Is About

The trial investigates the use of 3D transesophageal echocardiography TEE to analyze the right ventricles function in patients undergoing left ventricular assist device LVAD implantation. LVADs help support the left ventricle in patients with severe heart failure. Because right ventricular failure after LVAD implantation is common and linked to complications, this study aims to better predict which patients are at higher risk by using advanced 3D imaging methods. Participants receive one of several types of left-sided LVADs, including HeartMate III, HeartWare HVAD, or Levitronix CentriMag devices. During the LVAD implantation procedure, 3D TEE images of the right ventricle are taken and analyzed. The study focuses on gathering detailed heart function data and does not involve additional treatments or interventions beyond standard device implantation. During the study, researchers collect various heart function measurements within 24 hours after implantation, such as ventricular strain, volumes, ejection fractions, and tricuspid annular plane systolic excursion. Secondary outcomes include monitoring clinical data and lab tests over 14 days post-implantation. Participants are observed for right ventricular function and related support needs. The study started in March 2022 and will continue through January 2027, involving no experimental treatments beyond imaging and data collection.
