Multislice computed tomography to rule out coronary allograft vasculopathy in heart transplant patients.

Background: This study assessed if invasive coronary angiogram (CA) could be replaced by multislice (64- or 256-row) computed tomography (MSCT) to systematically rule out coronary allograft vasculopathy in heart transplant patients.

Methods: Electrocardiogram-gated contrast-enhanced MSCT (64-row for the first 25 patients and 256-row for the others) was compared with CA. MSCT parameters, adapted to the patient's weight, included 120 kV, 800 mAs, 0.
