Cardiac allograft vasculopathy : complications and imaging studies.

Cardiac allograft vasculopathy (CAV) is an accelerated form of coronary artery disease affecting both intramyocardial and epicardial coronary arteries and is observed in patients during long-term survival after cardiac transplantation. We report a case of CAV complicated with silent transmural myocardial infarction and massive left ventricular thrombus formation associated with silent pericarditis and with ischemic and non-ischemic scar tissue, as detected by cardiac magnetic resonance imaging (CMRI). The authors suggest CMRI as an additional technique along with echocardiography during follow-up of heart transplant recipients. CMRI may contribute to the early identification of areas of myocardial wall abnormalities suggestive of CAV, thus guiding diagnosis and prompt percutaneous treatment.
