What is the function of the LAD?
Function. The artery supplies the anterolateral myocardium, apex, and interventricular septum. The LAD typically supplies 45-55% of the left ventricle (LV) and is therefore considered the most critical vessel in terms of myocardial blood supply.
What is LAD disease of the heart?
A widowmaker heart attack occurs when the left anterior descending (LAD) artery, which supplies blood to the larger, front part of the heart, is blocked at its origin. “This artery delivers a major amount of blood to your heart,” Dr. Rampersad explains.
What is LAD procedure?
LIMA LAD is a life-saving coronary artery bypass procedure that involves the left internal mammary artery and the left anterior descending artery. It opens the heart’s blood flow, saving the life of the patient.
What does the LAD supply blood to?
The LAD provides blood to the anterior ventricular septum and the greater portion of the anterior portion of the left ventricle. The LCx supplies blood to the lateral wall of the left ventricle and sometimes to the posterior inferior aspect of the heart when there is left heart dominance.
Which artery is called the Widowmaker?
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 does LAD stand for in medical terms?
The left anterior descending artery (LAD) is the largest coronary artery runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex.
What are the symptoms of LAD?
Some of the warning signs and symptoms of a 100 percent LAD blockage include:
- feeling chest pain or discomfort.
- experiencing pain that radiates out into your arms, legs, back, neck, or jaw.
- having pain in your abdominal area that feels like heartburn.
- having muscle pain in your chest or neck that feels like a pulled muscle.
What is a LAD lesion?
Proximal left anterior descending coronary artery (LAD) lesions often supply a high percentage of the left ventricular myocardium, compared to proximal lesions in the circumflex or right coronary arteries.
Can a LAD be stented?
If the LAD disease is determined to be significant then a stent is often used to relieve the blockage. Sometimes bypass surgery is advised, and usually a vessel called the LIMA (left internal mammary artery) is used as the bypass vessel and is associated with very good long-term results.

What is the importance of the LAD artery?
It also provides collateral circulation to the anterior right ventricle, the posterior part of the interventricular septum, and the posterior descending artery. Importance in cardiovascular diseases: The LAD artery is the most commonly occluded of the coronary arteries.
Where does the LAD artery supply the left ventricle?
In general, the LAD artery and its branches supply most of the interventricular septum; the anterior, lateral, and apical wall of the left ventricle, most of the right and left bundle branches, and the anterior papillary muscle of the bicuspid valve (left ventricle).
Why is the lad used as a language acquisition device?
Rather, the LAD is used to explain what are most likely hundreds or thousands of underlying processes that humans have in their brains that have evolved to make us particularly exceptional at learning and understanding language.
Why did Chomsky come up with the lad theory?
The language acquisition device is a hypothetical tool in the brain that helps children quickly learn and understand language. Noam Chomsky theorized the LAD to account for the rapid speed at which children seem to learn language and its rules. LAD later evolved into Chomsky’s greater theory of universal grammar.
