Interarterial course of the right coronary artery
Updates to Article Attributes
Inter-arterial course of theright coronary artery (RCA), also known as amalignant variant, may occur if the right coronary artery has an aberrant aberrant origin from the the left coronary sinus. It is an uncommon anomaly with potential risk of cardiac ischaemia.
When the right coronary artery arises aberrantly in this manner, there are three possible courses it may take:
- inter-arterial with intramural segments: highest risk
- inter-arterial and extramural
- inter-atrial
An inter-arterial course occurs when the artery passes between the ascending aorta and the pulmonary trunk.
Treatment and prognosis
Some consider this anomaly malignant malignant, indicating that it has an increased risk of cardiac ischaemia, myocardial infarction, and possibly sudden death. Others consider the aberrant course of course of the right coronary artery to be less concerning than an aberrant aberrant course of the left coronary artery. Repair strategies vary depending on the institution's level of concern.
The cause of ischaemia ischaemia from this the anomaly is not completely understood. Classically, extrinsic compression of the coronary artery between between the aortic root and the right ventricular outflow tract was considered to be the primary problem, but there is increasing evidence that risk may be mostly due to the anomalous coronary's flow-limiting'slit'-like orifice.
The highest risk situation is considered to be the inter-arterial course with segments that course through the the wall of the aorta.
