[Non-invasive assessment of coronary artery bypass grafts by computed tomography: comparison with conventional coronary angiography].

Introduction And Objectives: Although it has been demonstrated that the diagnostic accuracy of computed tomography in the non-invasive assessment of major epicardial coronary arteries is high, only a few studies have evaluated the technique's reliability in assessing coronary artery bypass grafts. The aim of this study was to determine the diagnostic accuracy of multidetector computed tomography in the assessment of coronary grafts.

Patients And Method: We prospectively evaluated 117 coronary grafts in 38 patients who had undergone coronary artery bypass graft surgery and who had a clinical indication for angiographic graft assessment.
