title: Use of multislice computed tomographic coronary angiography for the diagnosis of anomalous coronary arteries.
abstract: The accurate diagnosis of anomalous coronary arteries by invasive angiography is limited by the inability to define the anatomic course in relation to surrounding structures. Computed tomographic coronary angiography has recently emerged as a noninvasive method to visualize the coronary arteries. Multislice computed tomography with up to 64 detector arrays, along with 3-dimensional rendering, has further improved the temporal and spatial resolution of noninvasive coronary imaging. In this series of cases, the investigators describe their institution's experience with computed tomographic coronary angiography as a complement to invasive coronary angiography in determining the origin and course of different anomalous coronary arteries in 16 patients. With the aid of 3-dimensional volume rendering, 6 anomalous right coronary arteries, 4 anomalous left circumflex coronary arteries, 4 single coronary arteries, and 2 anomalous left main coronary arteries were all clearly defined with regard to their origin and course. It is proposed that computed tomographic coronary angiography is the diagnostic test of choice in the evaluation of such anomalies.
