“…Recently, the use of MDCT for the detection of coronary anomalies is becoming more common [3,4]. This case report demonstrates the role that MDCT can play not only in detection but also in risk assessment of rare coronary anomalies both before and after surgical treatment.…”

“…This is a very rare anomaly, with a reported incidence of approximately 0.004% [3,4]. The risk of sudden cardiac arrest is greater in this subtype than in others because the proximal segment of the anomalous coronary artery courses between the aorta and the pulmonary artery, so that compression of the anomalous coronary artery between the aorta and pulmonary trunk can occur, especially during exercise [6].…”

“…Canbay et al have reported three cases of SCA (types L-I, R-I and R-II-B) that were diagnosed using CAG [8]. Ichikawa et al reported that MDCT revealed anomalous origin of the RCA in 15 of 3,212 patients [3]. More recently, another report has described several types of SCA, including one case of the R-II-B subtype, as assessed by means of MDCT [9].…”

Multi-Detector Computed Tomography (MDCT) has been used to detect coronary lesions in a number of earlier studies. Here, we describe a rare case of congenital anomaly of the coronary artery, i.e., the R-II-B subtype (Lipton classification) of single coronary artery (SCA). A 61 year old man with angina was referred to our hospital. Assessment by coronary angiography (CAG) suggested SCA. The R-II-B subtype was confirmed by MDCT. Coronary artery bypass grafting (CABG) was then performed, and success of the grafting was evaluated by post-CABG MDCT.This subtype of SCA has been reported to be associated with high risk of cardiac sudden death because the aberrant vessel, which passes between the aorta and the main pulmonary artery, is readily compressed by these arteries. This subtype of SCA is also very rare: there is only one previously reported case in which MDCT was used for diagnosis. Ours is the first case of this subtype in which MDCT together with CAG was used for evaluation both pre-and post-CABG. Our results show that MDCT may be useful not only prior to CABG for risk stratification in patients with anomalous coronary arteries but also after CABG for evaluation.

“…It has usually been described in the setting of congenital defects such as atrial septal defect, ventricular septal defect, and, more rarely, isolated persistent ductus arteriosus [4,5] . MSCT allows 3-dimensional visualization of the coronary arteries with high spatial resolution, and may be the most promising imaging modality for diagnosing these anomalies [4][5][6] . Surgical correction or coronary artery bypass grafting can be carried out with minimal risk and good anatomic and functional results [7,8] .…”

Right coronary artery from the left sinus of valsalva: Multislice CT and transradial PCI

A 42-year-old-woman presented with de novo crescendo angina. Thallium-scintigraphy showed inferior ischemia. Coronary angiogram revealed a right coronary artery (RCA), originating from the left sinus of Valsalva with a severe proximal systolic compression. She underwent successful transradial percutaneous coronary intervention with stent implantation. Multislice-computed tomography (MSCT) is usually used to evaluate coronary artery anomalies and can effectively show the anomalous RCA and the inter-arterial trajectory between the aorta and pulmonary arteries. Anomalies of the origin of the coronary arteries are rare, but can produce specific clinicopathological entities that should be diagnosed with accuracy. This case report illustrates the role of MSCT in the detailed description of an abnormal coronary artery and the use of stenting for symptoms relief.

“…Anomalous origin of the RCA is a frequently encountered type of congenital coronary artery anomalies, found in approximately 0.11% of patients undergoing conventional coronary angiography [3] and in 0.47% of those undergoing multidetector-row computed tomography angiography [4]. Percutaneous coronary interventions in patients with anomalous RCA are sometimes obscure because of difficulty in identifying the orifice and the course of the anomalous RCA [5].…”

Multislice computed tomographic findings of the anomalous origins of the right coronary artery: evaluation of possible causes of myocardial ischemia

Abstract: Coursing between the aorta and pulmonary artery, acute angle take-off and intramural course were thought to be major causes of exercise-induced ischemia in patients with anomalous origins of the RCA.
