An aberrant origin of the left main coronary artery (LM) or left anterior descending coronary artery (LAD) from the right sinus of Valsalva is a rare anomaly that has been associated with myocardial ischemia and sudden cardiac death.
The absence of the left main coronary artery with a separate origin of the left anterior descending and left circumflex arteries is found in up to 0.67% of subjects 2 and is considered a normal variant.
An anomalous coronary artery (ACA) is a coronary artery that has an abnormality or malformation. The malformation is congenital (present at birth) and is most often related to the origin or location of the coronary artery. However, there may be other defective areas in the coronary artery.
A common coronary artery anomaly is an artery coming out of the wrong aortic sinus of Valsalva. Normally, the right coronary artery comes out of the right aortic sinus of Valsalva. Similarly, the left coronary artery comes out of the left aortic sinus of Valsalva.
Anomalous origin of the Left Main Coronary Artery (LMCA) from the non-coronary cusp (NCC) is one of the rarest coronary anomalies and management remains controversial. Methods: Case. A 53-year-old man was admitted for non-ST elevation myocardial infarction.
The left coronary artery ends in the left anterior descending (LAD) and ramus (RM) branches. This is a case of clinically benign single coronary artery, which should more properly be called single coronary ostium because all the coronary arteries are present, though they are anomalous in their origin and course.
The most critical anomaly is the left main coronary artery (LMCA) arising from the right sinus of Valsalva (RSV) as it has a high risk of sudden cardiac death . The most common coronary artery anomaly is the left circumflex artery (LCX) arising from the RSV or right coronary artery (RCA).
An anomalous left main coronary artery with its origin from the pulmonary artery (ALCAPA) is one of the few clinically significant coronary anomalies.
Anomalous left coronary artery (ALCA) occurs when the left coronary artery, which carries blood to the heart, is connected to the pulmonary artery instead of the aorta. It is a rare problem, comprising less than 1% of all congenital heart defects in children.
In this webinar, Mayo Clinic cardiology experts Rajiv Gulati, M.D., Ph.D., and Marysia S. Tweet, M.D., M.S., discuss how to differentiate SCAD from other causes of acute coronary syndrome on coronary angiography, identify key SCAD management ...
