Aberrant subclavian artery, or aberrant subclavian artery syndrome, is a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch, occurring in approximately 1% of individuals.
Variant angina is caused by a spasm in a coronary artery that supplies the heart muscle with blood, oxygen, and nutrients. spasm is a sudden, temporary narrowing or tightening of a small part of an artery. This spasm results in a temporary situation where the heart does not get enough blood. The blockage of blood flow causes the characteristic chest pain associated with angina.
