Left main coronary artery
The left main coronary artery (LMCA) or left coronary artery (LCA) is one of the two main coronary arteries that supply the heart with oxygenated blood.
Gross anatomy
Origin
The left main coronary artery is a branch of the ascending aorta, with its normal origin in the left aortic sinus, just...

Ramus intermedius artery
The ramus intermedius is a variant coronary artery resulting from trifurcation of the left main coronary artery 1. It is present in ~20% (range 15-30%) 2,3 of the population.
It can have a course similar to the obtuse marginal branches of the left circumflex artery or the diagonal branches of t...

Coronary MR angiography
Coronary MR angiography (coronary MRA) is a developing approach to imaging the coronary arteries.
Advantages of coronary MRA include avoidance of the intravenous iodinated contrast and ionizing radiation used in coronary CT angiography and conventional angiography.
A disadvantage of coronary M...

Coronary veins
The coronary veins return deoxygenated blood from the myocardium back to the right atrium. Most venous blood returns via the coronary sinus. Coronary venous anatomy is highly variable, but is generally comprised of three groups:
cardiac veins which drain into the coronary sinus:
great cardiac ...
Article
Coronary sinus
The coronary sinus is the largest cardiac venous structure. It returns the majority of the blood supply for the left ventricle to the right atrium.
Gross anatomy
The coronary sinus courses along the posterior wall of the left atrium into the left atrioventricular groove. It normally drains int...

Coronary artery disease
Coronary artery disease (CAD) is primarily due to the narrowing of the coronary arteries due to atherosclerosis, which results in myocardial ischemia and is the leading cause of mortality globally.
Diagnosis
The diagnosis of coronary artery disease is based on typical imaging criteria either ...

Kugel's artery
An uncommon variant of coronary arterial anatomy, Kugel's artery was originally described as an anastomotic communication between branches of the proximal left circumflex artery with the distal right coronary artery. These coronary trunks often communicate indirectly through atrial anastomotic n...

Retroaortic anomalous coronary sign (echocardiography)
The retroaortic anomalous coronary (RAC) sign describes the sonographic appearance of an anomalous left coronary artery traveling posteriorly to the aortic root. It is most commonly observed with anomalous origin of the left circumflex artery from the right sinus of Valsalva, but is also describ...
