Abstract

Coronary angiography is a standard method used for selection of patients for percutaneous transluminal coronary angioplasty (PTCA) and for estimation of the immediate results of PTCA. Intravascular ultrasound (IVUS) is a new method for assessment of morphology of coronary arteries. The aim of the present study was to compare the accuracy of both methods in assessment of the coronary wall morphology before and after PTCA. In 46 patients who underwent PTCA, 55 coronary stenoses were found. Angiographic diagnosis of the stenoses concentricity was confirmed by IVUS in 69% of cases. Compared to IVUS results, 62% of concentric and 12% of eccentric lesions were misdiagnosed by angiography. Coronary wall dissection following PTCA was found in 11 (20%) patients using angiography and in 18 (33%) patients by means of IVUS. The presence of calcified lesions was associated with higher frequency of plaque fractures and wall dissections after PTCA (84% versus 50%, p
