Which main coronary artery bifurcates into?
Left coronary artery
What is the RCA coronary artery?
Right coronary artery (RCA). The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm.
Is left main artery same as lad?
Left Main Coronary Artery (also called the left main trunk) Left Anterior Descending artery (LAD)
What is LAD and RCA disease?
LAD: left anterior descending coronary artery; LCx: left circumflex coronary artery; RCA: right coronary artery; SCA: single coronary artery. This case demonstrates a rare congenital coronary artery anomaly found incidentally with a presentation of atypical angina and three-vessel coronary artery disease (CAD).
Which main coronary artery bifurcates into smaller ones?
The left coronary artery typically runs for 10 to 25 mm, and then bifurcates into the anterior interventricular artery (also called the left anterior descending (LAD) and the Widow maker) and the left circumflex artery (LCx).
Does the right coronary artery bifurcate?
In right dominance, the distal RCA at the level of the crux of the heart typically bifurcates into the PDA and a posterolateral branch. The PDA courses in the posterior ventricular septum giving origin to the SA nodal artery and posterior ventricular branch. In left dominance, the PDA originates from the distal LCx.

Where does the left main coronary artery originate?
Origin. The left main coronary artery is a branch of the ascending aorta, with its normal origin in the left aortic sinus, just superior to the aortic valve 1,2.
What happens if RCA is blocked?
When one or more of the coronary arteries suddenly becomes completely blocked, a heart attack (injury to the heart muscle) may occur. If the blockage occurs more slowly, the heart muscle may develop small collateral blood vessels (or detours) for other coronary arteries to reroute the blood flow, and angina occurs.
What is coronary RCA?
The right coronary artery (RCA) is one of the two main coronary arteries that supply the heart with oxygenated blood.
Which coronary artery is most commonly blocked?
Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur. The extent of the blockage can vary widely from 1% to 100%.
What symptoms can you typically expect to see in a right coronary artery RCA blockage?
Symptoms of coronary artery disease include:
- Heaviness, tightness, pressure, or pain in the chest behind the breastbone.
- Pain spreading to the arms, shoulders, jaw, neck, or back.
- Shortness of breath.
- Weakness and fatigue.
Is lad the main artery?
The LAD is considered the most important of the three main coronary arteries and is almost always the largest. It’s called the LAD because is on the left side of the heart (left) it runs down the front wall of the heart (anterior descending).
Is lad the same as left main?
Left Main Coronary Artery (also called the left main trunk) Left Anterior Descending artery (LAD)
What is another name for the LAD artery?
The left anterior descending (LAD) artery, also known as the anterior interventricular branch, is one of the two branches of the left coronary artery (the other branch being the circumflex (Cx) artery).
Can the left main artery be stented?
Left main coronary artery stenting is typically suitable for patients who are at high risk for surgical complications or have comorbidities.
What is LAD and RCA in heart?
The left anterior descending artery gives off the diagonal branches. The RCA supplies blood to the right side of the heart. The sinoatrial nodal branch of the RCA provides blood to the SA node, and the atrioventricular nodal artery delivers blood to the AV node.
Is LAD blockage serious?
The total blockage of the LAD artery is a serious problem that requires immediate treatment. Delayed treatment for a heart attack can lead to significant tissue damage and scarring. It can be life threatening or lead to permanent disability. Not all heart attacks start with crushing chest pain or arm numbness.
What is RCA in the heart?
Right coronary artery (RCA). The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm.
What causes LAD disease?
The LAD most commonly gets blocked up with plaque from cholesterol. This condition is known as atherosclerosis, often called the hardening of the arteries. Plaque can cause blood clots that obstruct the artery.
What does the left coronary artery branch into?
Right coronary artery (RCA). The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm.
Is left main the same as left coronary artery?
The left coronary artery, which branches into the left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart. The left side of the heart is larger and more muscular because it pumps blood to the rest of the body.
What are the 5 main coronary arteries?
The left coronary artery (abbreviated LCA) is a coronary artery that arises from the aorta above the left cusp of the aortic valve, and feeds blood to the left side of the heart muscle. It is also known as the left main coronary artery (abbreviated LMCA) and the left main stem coronary artery (abbreviated LMS).
What does the right coronary artery divide into?
The right coronary artery divides into smaller branches, including the right posterior descending artery and the acute marginal artery. Together with the left anterior descending artery, the right coronary artery helps supply blood to the middle or septum of the heart.
What is the difference between right and left coronary artery?
The right coronary artery supplies blood mainly to the right side of the heart. The right side of the heart is smaller because it pumps blood only to the lungs. The left coronary artery, which branches into the left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart.
