THE USEFULNESS OF VESSEL FRACTIONAL FLOW RESERVE FOR ASSESSING CARDIAC GRAFT VASCULOPATHY IN HEART TRANSPLANT RECIPIENTS

Cardiac graft vasculopathy (CAV) remains the Achilles’ heel of long-term survival after heart transplantation (HTx). The severity of CAV is graded with coronary angiogram (COR) which has several known limitations. Vessel fractional flow reserve (vFFR) derived from COR has emerged as a new
