“…In addition several studies have demonstrated superiority of CCTA over ICA [30] in detecting coronary anomalies leading to a 100% identification rate of anomalies when analyzed with CCTA compared to 53% with ICA in a small series of 16 patients [31]. CCTA has recently been advocated as first-line method for known or suspected anomalies by the American College of Cardiology, provided appropriate criteria are used [32].…”

BackgroundAs coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative for evaluation of coronary anatomy with a lower referral threshold than invasive coronary angiography (ICA), the prevalence of coronary anomalies in CCTA may more closely reflect the true prevalence in the general population. Morphological features of coronary anomalies can be evaluated more precisely by CCTA than by ICA, which might lead to a higher identification of congenital coronary anomalies in CCTA compared to ICA.To evaluate the incidence, clinical and morphological features of the anatomy of patients with coronary anomalies detected either by coronary computed tomography angiography (CCTA) with prospective ECG-triggering or invasive coronary angiography (ICA).MethodsConsecutive patients underwent 64-slice CCTA (n = 1′759) with prospective ECG-triggering or ICA (n = 9′782) and coronary anatomy was evaluated for identification of coronary anomalies to predefined criteria (origin, course and termination) according to international recommendations.ResultsThe prevalence of coronary anomalies was 7.9% (n = 138) in CCTA and 2.1% in ICA (n = 203; p < 0.01). The most commonly coronary anomaly detected by CCTA was myocardial bridging 42.8% (n = 59) vs. 21.2% (n = 43); p < 0.01, while with ICA an absent left main trunk was the most observed anomaly 36.0% (n = 73; p < 0.01). In 9.4% (n = 13) of identified coronary anomalies in CCTA 9.4% were potentially serious coronary anaomalies, defined as a course of the coronary artery between aorta and pulmonary artery were identified.ConclusionThe prevalence of coronary anomalies is substantially higher with CCTA than ICA even after exclusion of patients with myocardial bridging which is more frequently found with CCTA. This suggests that the true prevalence of coronary anomalies in the general population may have been underestimated based on ICA.

“…An anomalous left coronary artery originating from the RSV may have four pathways: between the aortic root and pulmonary artery (interatrial course), a trans-septal course (subpulmonic course), anterior to the right ventricular outflow tract (anterior or prepulmonic course) and posterior to the aortic root (retroaortic course). Left coronary arteries coursing between the aorta and pulmonary artery are known to have a high risk of sudden death in young men (4).…”

Anomalous Origin of the Left Circumflex Artery from the Right Sinus of Valsalva: Non-ST-segment Elevation Myocardial Infarction

An anomalous origin of the left coronary artery from the right sinus of Valsalva (RSV) is rare. We herein report the case of an 80-year-old woman who presented to the emergency department with chest pain. Emergent coronary angiography was performed following a diagnosis of non-ST segment elevation myocardial infarction. A right coronary angiogram showed that the common trunk originating from the RSV branched into the left anterior descending and right coronary arteries. Although the initial angiogram failed to show the left circumflex artery (LCx), considered to be the culprit vessel, computed tomographic angiography demonstrated that the LCx was located immediately below the common trunk and exhibited a retroaortic course. We successfully treated the patient and obtained optimal angiography results.

“…Regarding MB, all three studies agree that MB is a normal variant although the frequency of each report is slightly different (9.8% vs. 3.2% vs. 21.6%, respectively). On the other hand, regarding aneurysm, Andreini et al (34) reported 1.1% and Bazzocchi et al (35) reported 0.7%. Regarding type 1 dual LAD, Bazzocchi et al reported 0.06%.…”
