ECG-gated multi-detector row CT provides accurate, noninvasive depiction of coronary artery anomalies and is superior to conventional angiography for delineating ostial origin and proximal path.
Does ECG-gated multi-detector row CT improve the depiction of coronary artery anomalies compared to conventional angiography in patients with suspected anomalies?
ECG-gated multi-detector row CT is a superior, noninvasive imaging modality for delineating the ostial origin and proximal path of anomalous coronary arteries compared to conventional angiography.
Congenital abnormalities of the coronary arteries are an uncommon but important cause of chest pain and, in some cases of hemodynamically significant abnormalities, sudden cardiac death. For several decades, premorbid diagnosis of coronary artery anomalies has been made with conventional angiography. However, this imaging technique has limitations due to its projectional and invasive nature. The recent development of electrocardiographically (ECG)-gated multi-detector row computed tomography (CT) allows accurate and noninvasive depiction of coronary artery anomalies of origin, course, and termination. Multi-detector row CT is superior to conventional angiography in delineating the ostial origin and proximal path of an anomalous coronary artery. Familiarity with the CT appearances of various coronary artery anomalies and an understanding of the clinical significance of these anomalies are essential in making a correct diagnosis and planning patient treatment.
Kim et al. (Wed,) conducted a review in Coronary artery anomalies. ECG-gated multi-detector row CT vs. Conventional angiography was evaluated. ECG-gated multi-detector row CT provides accurate, noninvasive depiction of coronary artery anomalies and is superior to conventional angiography for delineating ostial origin and proximal path.
