What is malformation of coronary vessels?
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.
What is the most common cause of coronary artery abnormalities?
Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis.
Can you live with anomalous coronary artery?
While most people with an anomalous coronary artery aren’t in danger, the problem can be very dangerous for some. Sometimes people don’t have symptoms until they have a sudden cardiac arrest. Fortunately, several surgical options can protect you from sudden death and help you have a normal life.
What causes coronary artery anomaly?
What causes an ACA in a child? Most congenital heart problems have no known cause. An ACA may happen with other congenital heart problems. For instance, it may occur with transposition of the great arteries (TGA) and tetralogy of Fallot (TOF).
Where is the OM in the heart?
The obtuse marginal (OM) arteries sometimes referred to as lateral branches are branch coronary arteries that come off the circumflex artery. There can be one or more obtuse marginal arteries. It typically traverses along the left margin of heart towards the apex.
What are the types of coronary artery disease?
There are three main types of coronary heart disease: obstructive coronary artery disease, nonobstructive coronary artery disease, and coronary microvascular disease.
Where is the Widowmaker located?
The widow-maker is a massive heart attack that occurs when the left anterior descending artery (LAD) is totally or almost completely blocked. The critical blockage in the artery stops, usually a blood clot, stops all the blood flow to the left side of the heart, causing the heart to stop beating normally.
What is OM1 cardiac?
It typically traverses along the left margin of heart towards the apex. The first obtuse marginal artery (OM1) is usually found on or close to the obtuse margin of the heart and is also known as the “margo obtusus”.
