“…The diagnosis of anomalous origin of coronary artery from other arteries can be challenging. Most of the coronary anomalies are asymptomatic and benign but may cause myocardial ischemia and sudden death [ 50 ] . Anomalous origin of coronary artery is often associated with a pathophysiologic state of inadequate tissue perfusion and subsequent hypoxia [ 51 ] .…”

ObjectiveAnomalous origin of coronary artery is uncommon. The taxonomies of anomalous origin of coronary artery are inconsistent and complex. Conceptual and therapeutic debates remain. The aim of the present study is to reappraise the concept of anomalous origin of coronary artery and to discuss the potential hazards and treatment rationale of this anomaly on basis of literature review.MethodsA comprehensive literature review was made in terms of the taxonomies including “simple”, “multiple” and “complex” types of anomalous origin of coronary artery.ResultsAnomalous origin of coronary artery can be simply categorized according to the ectopically originated coronary artery. There are a couple of complex anatomical variants: “multiple” type, involving more than one coronary artery or branch, which can be subdivided into 2 subtypes, A) more than one coronary arteries or branches arising from one place; and B) two coronary arteries/branches arising from separate ectopic sites; and “complex” type, associated with acquired heart disease, or congenital heart defects.ConclusionSudden cardiac death in anomalous origin of coronary artery is associated with the anatomical features including abnormal coursing, acute angle take-off and ostial abnormalities. Atherosclerosis is prone to be in the right-sided ectopic and retroaortic coursing coronary artery. Surgical treatment is a definitive therapy. Simple coronary artery bypass grafting is not recommended due to the potential hazards of coronary steal phenomenon and poor patency of mammary arterial grafts, and modified maneuvers such as coronary ostial reimplantation, impinged coronary segment unroofing and coronary stent deployment are advocated instead.

“…Coronary anomalies are a group of congenital disorders with highly variable pathophysiological mechanisms and manifestations [ 1 ]. Most of the coronary anomalies are asymptomatic and benign but may cause acute coronary syndrome and sudden cardiac death [ 2 ]. Most coronary anomalies are found incidentally during coronary angiography, and 0.6% to 1.55% of patients with coronary artery anomalies are found [ 3 ].…”

Percutaneous Coronary Intervention in an Octogenarian With Anomalous Origin Arising From Right Sinus: A Rare Case Report

et al. 2020

Anomalous coronary artery origins are not common in routine clinical practice. The incidence of coronary anomalies in patients undergoing coronary angiography is less than 1%. The greatest challenges faced in the management are delays in identification and difficulty engaging the anomalous coronary artery. Operator experience in promptly identifying the anomaly and selection of the appropriate catheter is critical for successful intervention. We are presenting a case of acute inferior and posterior wall myocardial infarction (MI) with an anomalous origin of the left circumflex artery from the right coronary sinus. Learning objective is that percutaneous coronary intervention (PCI) in an anomalous left circumflex can be technically difficult because selective cannulation of the vessel may not be easy. An anomalous left circumflex artery has a rare presentation of ST-elevation myocardial infarction (STEMI). Complicated STEMI with cardiogenic shock is not commonly seen in anomalous coronary artery origin from the right sinus. Percutaneous intervention in patients with STEMI with an anomalous left circumflex artery has a high risk and is technically challenging.
