• Coronary angiography is the reference method for the detection of coronary disease of the cardiac grafts which threatens the long-term prognosis of cardiac transplantation. The primary results of treatment for slowing, stabilising or even improving coronary transplant disease are encouraging and make necessary the development and evaluation of reliable diagnostic methods. The authors undertook a prospective study of 48 asymptomatic patients with normal graft wall motion between January 1995 and March 1997 to compare the results of coronary angiography and endocoronary ultrasonography. The patients had been transplanted in the 10 years preceding the study. The results of the two methods were concordant in 33 cases (69%) (NS), for the confirmation (9 cases) or the information of coronary transplant disease (24 cases). The results were contradictory in 15 cases (31%): in 12 cases, endocoronary ultrasonography showed signs of coronary disease whereas the coronary angiography was estimated to be normal: in the remaining 3 cases, coronary angiography was abnormal but no signs of coronary disease were found on endocoronary ultrasonography. The specificity of coronary angiographic detection was 89% and therefore very satisfactory, but its sensitivity (43%) was poor. In addition, endocoronary ultrasonography allows analysis of the extension of coronary lesions to unstenosed segments, the quantification of intimal thickening. Therefore, endocoronary ultrasonography should become the reference investigation for coronary disease of cardiac transplants.
