“…Another describes SCD in a patient who was subsequently found to have no evidence of obstructive atherosclerosis but did have an anomalous LCx artery branching from the right sinus of Valsalva [ 14 ]. Others describe the variant as an incidental finding after undergoing angiography for another indication [ 4 , 15 , 16 ]. Although individual case reports have indicated adverse events, large-scale studies examining this variant did not report an increased incidence of SCD, angina, atherosclerosis, or myocardial infarction, and all have described it as benign [ 7 , 9 , 17 ].…”

Coronary artery anomalies are rare in the general population. Many individuals with coronary artery anomalies are asymptomatic. Some individuals with these anomalies have an increased risk of sudden cardiac death (SCD), especially young athletes, and an elevated risk of myocardial ischemia with anginal symptoms, seen in older age groups.We report a 43-year-old male who received coronary artery bypass graft (CABG) surgery for the four-vessel disease after suffering from an anteroseptal myocardial infarction (MI). The patient presented to the hospital emergency department with episodes of chest pain for three days. On coronary angiography, an anomalous origin of the left circumflex coronary artery (ALCx) was visualized. This ALCx was a type I variant originating from a separate ostium from the right coronary artery (RCA) at the right coronary cusp.It is important to document and describe the different variants of coronary anomalies to provide proper patient management. The anomalous origin of the left circumflex coronary artery from the right coronary cusp of the RCA is considered a benign variant. It may, however, have been instrumental in supplying blood to the left heart in the setting of complete left coronary artery (LCA) occlusion.

“…16 Even if three-dimensional transesophageal echocardiography can be useful in the visualization of anomalous coronary arteries before operation, it is not a routine tool for the diagnosis of CAAs. 17 Coronary CTA and magnetic resonance angiography (MRA) are the imaging modalities with a Class I recommendation for the visualization of CAAs. 5,6 When comparing these two modalities, cardiac CTA is superior for imaging CAAs due to higher spatial and temporal resolution, better visualization of the surrounding structures, and lower cost.…”

AbstractIntroduction: The diagnosis of coronary artery anomalies (CAAs) can be challenging due to the highly variable manifestations and symptoms. CAAs occur in less than 1% of the population. Multidetector cardiac computed tomography angiography (CTA) provides excellent spatial and temporal resolution for the imaging of CAAs. This case report describes an anomalous origin of the left main coronary artery.Case presentation: A 64-year-old woman with atypical chest pain underwent coronary CTA. The CT demonstrated that the left coronary artery was originating from the right coronary sinus and had an interarterial course with an approximately 50% stenosis at the segment between the great arteries. Invasive coronary angiography confirmed hemodynamically significant stenosis of the interarterial segment. The patient underwent off-pump coronary artery bypass graft surgery.Conclusion: Left coronary artery originating from the right coronary sinus with an interarterial course increases the risk of sudden cardiac death. In these patients, surgical revascularization is recommended. However, timely diagnosis, especially in those with mild symptoms, remains challenging. Coronary CTA is a robust tool to diagnose CAA and provides valuable information to support the clinical decision making in this patient population.

Anomalous aortic origin of a coronary artery (AAOCA) from the inappropriate sinus of Valsalva is increasingly recognized by cardiac imaging. Although most AAOCA subtypes are benign, autopsy studies report an associated risk of sudden death with interarterial anomalous left coronary artery (ALCA) and anomalous right coronary artery (ARCA). Despite efforts to identify high-risk ALCA and ARCA patients who may benefit from surgical repair, debate remains regarding their classification, prevalence, risk stratification, and management. We comprehensively reviewed 77 studies reporting the prevalence of AAOCA among >1 million patients, and 20 studies examining outcomes of interarterial ALCA/ARCA patients. Observational data suggests that interarterial ALCA is rare (weighted prevalence = 0.03%; 95% confidence interval [CI]: 0.01% to 0.04%) compared with interarterial ARCA (weighted prevalence = 0.23%; 95% CI: 0.17% to 0.31%). Recognizing the challenges in managing these patients, we review cardiac tests used to examine AAOCA and knowledge gaps in management.
