MARINER Trial: Multiparametric Cardiac PET for CAV Surveillance After Heart Transplantation (NCT06089486)

Multiparametric Cardiac Positron Emission Tomography for Cardiac Allograft Vasculopathy Surveillance After Heart Transplantation

๐ŸŸข Recruiting Observational / Diagnostic ๐Ÿ“‹ Clinical Research Protocol Sponsor: Ottawa Heart Institute Research Corporation

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

Cardiac allograft vasculopathy (CAV) is a common complication affecting heart transplant patients. This condition causes narrowing of the heart arteries leading to graft dysfunction. Surveillance for CAV is vital; however an ideal approach has not been established. The goal of this study is to assess whether noninvasive positron emission tomography (PET) based surveillance is non-inferior to invasive coronary angiography (ICA) surveillance.
