Clinical Trial Summary

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.


Clinical Trial Description

MARINER is a Canadian multicentre prospective, randomized clinical outcomes-based trial evaluating noninferiority of a noninvasive PET strategy compared to ICA for CAV surveillance. Patients are randomized to annual PET or ICA for CAV surveillance. Non-inferiority is assessed according to a clinical composite of death, retransplant, allograft dysfunction not related to acute rejection, and angiographic CAV associated with myocardial infarction or heart failure. Secondary outcomes include the rate of new or progressive CAV, number of ICA performed, number of ICA and PET procedural related complications, EuroQol-5 Dimension assessed patient health-related quality of life and health care resource use. ;
