| Popis: | Background Coronary angiography is the gold standard for diagnosing coronary artery fistulas (CAFs). Multidetector computed tomography (MDCT) is a recently developed imaging technique for detecting coronary artery stenosis, coronary artery anomalies, and coronary artery fistulas and their courses. Objective We aimed to determine accuracy or sensitivity of MDCT in patients having CAF. Method We evaluated 13 patients with 15 CAFs detected earlier by coronary angiography. MDCT was carried out on all patients and the results were compared with coronary angiography, following which, sensitivity of MDCT was detected. Results Eleven of 15 CAFs were shown on MDCT and the overall sensitivity of MDCT was found to be 73%. Seven of 8 CAFs that coursed between two vascular structures were detected and the sensitivity of MDCT in this group was found to be 87%. However, the sensitivity of 58% of MDCT in patients with fistula coursing between coronary arteries and cardiac chambers was found. Conclusion Although coronary angiography is the gold standard diagnostic test for detection of CAF, MDCT may be an alternative test, especially, for CAF coursing between vascular structures, to detect origin, course, and the drainage site of fistula through its excellent spatial resolution and ability to show relationship of anatomic structures.
