简介
Aims
Cardiac allograft vasculopathy (CAV) is a leading cause of death in orthotopic heart transplant (OHT) survivors. Effective non-invasive screening methods are needed. Our aim was to investigate the added diagnostic and prognostic value of myocardial blood flow (MBF) to standard myocardial perfusion imaging (MPI) with positron emission tomography (PET) for CAV detection.
Methods and results
We studied 94 OHT recipients (prognostic cohort), including 66 who underwent invasive coronary angiography and PET within 1 year (diagnostic cohort). The ISHLT classification was used as standard definition for CAV. Positron emission tomography evaluation included semiquantitative MPI, quantitative MBF (mL/min/g), and left ventricular ejection fraction (LVEF). A PET CAV severity score (on a scale of 0–3) was modelled on the ISHLT criteria. Patients were followed for a …
