The Value of Sixteen-Detector Row Computed Tomographic Angiography For the Evaluation of Anomalous Coronary Arteries

Objective:To evaluate the value of sixteen-detector row computed tomographic angiography(CTA) for the evaluation of anomalous coronary arteries. Method: This study included consecutive 216 patients who were performed CTA. All CTA procedures were performed with retrospective electrocardiogram gating method. If the anomalous coronary arteries were detected, the results would be confirmed by conventional invasive coronary angiography (CAG). The results of CTA and CAG were evaluated by two experienced doctors. Result: Of all 216 patients, CTA identified 5 patients with an anomalous coronary artery. Of these 5 cases, the anomalous coronary arteries were RCA or side branch of RCA-Conus. RCA originated from the left sinus of Valsalva in 3 cases; RCA originated from the proximal segment of LAD in 1 case; Conus coursed between the aortic root and pulmonary artery to the anterior wall of the heart in 1 case. The above results were confirmed by CAG. Conclusion: Sixteen-detector row CT angiography(CTA)technology can accurately evaluate anomalous coronary arteries.
