Abstract Percutaneous coronary angioscopy and intravascular ultrasound are sensitive intravascular imaging methods for detecting early changes in coronary morphology in cardiac transplant recipients. To compare the 2 imaging modalities, 29 consecutive cardiac transplant recipients underwent percutaneous coronary angioscopy and intravascular ultrasound during annual coronary angiography. Surface morphology, presence of plaque, and percent area stenosis were determined with each procedure. Percutaneous coronary angioscopy was more sensitive in detecting the presence of plaque and stenosis than was coronary angiography (plaque: 79 vs 10% [p <0.001]; and stenosis: 24 vs 3°;; A [p <0.01]). Intravascular ultrasound was also more sensitive in detecting plaque (76 vs 10%; p <0.001) and stenosis (45 vs 3%; p <0.001) than was coronary anglography. Although both angioscopy and ultrasound identified atherosclerotic plaque, only percutaneous coronary angiroscopy could show luminal surface morphology and pigmentation of the plaque. Conversely, ultrasound could detect calcification and presence of intimal thickening, and was more accurate in assessing the severity of stenosis (45 vs 24%; p <0.01). In conclusion, percutaneous coronary angioscopy and intravascular ultrasound, in conjunction, provide information not only regarding the appearance of the luminal surface, but also quantitative information regarding the structure and extent of the disease in the coronary artery wall.
