Congenital coronary artery anomalies
Updates to Article Attributes
Congenital coronary artery anomalies (CCAAs) are not common, found only in ~1% (range 0.1-2%) of patients1,3.The most important finding to look for is the "malignant" course of anomalous coronary artery, namely, does the artery run between big pulsating objects - RVOT and pulmonary artery on one side and aorta on the other. Exacerbated pulsations during or just after exercise can sometimes compress the coronary artery enough to cause severely diminished blood flow to myocardium, which can cause re-entry phenomenon in the myocardium and sudden cardiac death due to VF or sustained VT.
In most cases, it is the right coronary artery, which has such a "malignant" course, and it is young adults or even teenagers, who die because of this. It is estimated that around a quarter of sudden cardiac deaths in this population is caused by malignant coronary artery course.
Next thing to look for and which can cause anginal pain at exertion, is an intramural course of a coronary artery (known as myocardial bridging). Usually, it is the midLAD, which has such a course. Describe location (LAD segment), length and depth of bridging in your report.
Of course, every anomalous coronary artery course should course should be described, if not for anything else, then for the interventional cardiologist, who should know about this 7.
Pathology
A vast number of different coronary artery abnormalities have been described, and are discussed separately separately (see related articles).
