A significant coronary lesion is a narrowing or blockage in a coronary artery that impairs blood flow to the heart muscle, typically defined as a stenosis of 70% or greater in a major artery or 50% or greater in the left main coronary artery. This level of obstruction can lead to ischemia, angina, or even myocardial infarction (heart attack) if not addressed. Identifying significant lesions is crucial for determining the need for interventions like angioplasty or coronary artery bypass grafting.
What else can I help you with?
Which lesion in a coronary artery do physicians normally consider higher risk proximal lesion or distal lesion?
Proximal lesion
Can an angioplasty be performed to repair a main coronary branch lesion?
Yes
Why is a lesion in the left main coronary branch more dangerous than any other coronary lesion?
A lesion in the left main coronary branch is more dangerous because it supplies blood to a larger area of the heart compared to the other coronary branches. A blockage in the left main coronary artery can lead to a more extensive myocardial infarction and potentially life-threatening consequences such as cardiac arrest. Immediate medical intervention is crucial in such cases.
Significant LAD lesion?
A significant LAD (Left Anterior Descending) lesion refers to a substantial narrowing or blockage in the LAD artery, which supplies blood to the front portion of the heart. This condition can lead to reduced blood flow, increasing the risk of heart attack and other cardiovascular complications. Diagnosis typically involves imaging studies such as angiography, and treatment may include medication, angioplasty, or coronary artery bypass surgery, depending on the severity of the lesion. Early intervention is crucial to prevent serious heart-related issues.
What was pathophysiology of acute coronary syndrome?
acs develop with cholestrol lesion deposit in to our vessel of blood and blood stream distrub due to cholestrol lesion in the inner side of vessel and blood supply distrub due to this,and cause atheriosclorosis and angina,stroke and mi.
What indicates a need for surgery in cases of coronary artery disease?
A finding of significant narrowing of the left main coronary artery and/or blockage or severe narrowing in the high, left anterior descending coronary artery.
What is the most prominent sign of coronary artery disease?
narrowing or blockage (stenosis) in the coronary arteries, with narrowing greater than 50% considered significant
A back flow of blood in the heart is?
A medical lesion. If it becomes significant it can be life threatening.
What is a space occupying lesion?
Substantial physical lesions, e.g. neoplasm, hemorrhage, granuloma, which occupy space; the effect is more significant if the lesion is within a space confined by bone, e.g. thorax, cranium, bone marrow cavity.
What causes Dieulafoy's lesion?
Dieulafoy’s lesion is caused by a small, abnormally large artery located close to the surface of the stomach or intestinal mucosa, which can lead to significant gastrointestinal bleeding. The exact etiology is not completely understood, but it is believed to be associated with factors such as mucosal erosion, ulceration, or inflammation. This lesion is often idiopathic, meaning it can occur without a clear underlying cause. Diagnosis typically involves endoscopy, where the lesion can be identified and treated.
Is a lesion a pathological site?
A 'lesion' is anything or any site of the body that is not normal.Yes, a lesion is a pathological site.
When is coronary artery bypass grafting actually performed?
It is used when there is nearly complete or totally complete blockage in one or more coronary arteries (often after myocardial infarction/heart attack or coronary syndrome, in which there has been no loss of functioning heart muscle, but there has been significant chest pain along with functional decline).
