Coronary allograft vasculopathy (CAV) is responsible for long term mortality after heart transplant (HTx). Myocardial perfusion impairment resulting from CAV can lead to early graft dysfunction. Our study aimed to quantify perfusion and 3-directional myocardial velocities by cardiac magnetic resonance perfusion and tissue phase mapping (TPM) sequences and describe the relationship at global and segmental level. Thirty two HTx patients affected by CAV were analyzed. Myocardial perfusion reserve was reduced in CAV patients and associated with reduced left ventricular twist during contraction. LV diastolic radial velocities and interventricular synchrony were associated as to rest and to stress myocardial perfusion variations
