| Abstract | BACKGROUND Invasive coronary angiography (ICA) is the gold standard for the diagnosis of coronary artery disease and also for imaging procedures for preoperative planning of coronary artery bypass grafting (CABG). Sixteen-multidetector row computed tomography (MDCT) represents an alternative depiction of coronary vessels. METHODS Preoperative exams included ICA and MDCT in 50 patients. Two blinded surgical readers independently investigated both diagnostic modalities regarding location, severity, and morphology of the stenoses. The right coronary artery, left anterior descending branch, and circumflex branch--each divided in 3 sections--and the left main artery with a diameter (3) 1.5 mm were rated in both procedures, and the percentage of complete evaluations by MDCT was assessed. RESULTS Heart rate was 72 +/- 8 bpm. Forty-six percent of patients received a complete MDCT evaluation, and 54% received an incomplete MDCT evaluation. In 62% of these incompletely examined patients, 1 branch was not completely analyzable, in 31% 2 branches; and in 7% all 3 branches. In total, 9% of all segments were incompletely assessed. Investigators detected coronary stenoses in complete evaluations with a sensitivity of 94% and a specificity of 95%. Positive predictive value was 87% and negative predictive value was 98%. Plaque classification in soft and hard plaques was possible. CONCLUSION Sixteen-MDCT is not a viable alternative diagnostic tool at present. However, although the percentage of incomplete evaluated patients is more then 50%, only 9% of all segments were incompletely assessable. If this technology can be further improved, especially its software, it will become a valid diagnostic tool for coronary artery disease. |
