Impact of plaque burden on compensatory enlargement of coronary arteries in cardiac allograft vasculopathy. Working Group on Cardiac Allograft Vasculopathy.

Using intravascular ultrasound, we demonstrated plaque-induced compensatory enlargement of coronary arteries in cardiac allograft vasculopathy. Besides intimal hyperplasia, adaptive remodeling processes of vessel and luminal geometry have physiologic and prognostic importance.
