Widow maker is an alternative name for the anterior interventricular branch of the left coronary artery. [9] [3] The name widow maker may also apply to the left coronary artery [10] or severe occlusions to that artery. [11] [12] This term is used because the left main coronary and/or the left anterior descending supply blood to large areas of ...
Widowmaker (forestry), any loose overhead debris such as limbs or tree tops that may fall at any time Widow maker (medicine), a nickname used to describe a highly stenotic left main coronary artery or proximal left anterior descending (LAD) coronary artery of the heart, which is very often fatal
[citation needed] The left coronary artery typically runs for 10–25 mm, then bifurcates into the left anterior descending artery, and the left circumflex artery. [1] The part that is between the aorta and the bifurcation only is known as the left main artery (LM), while the term "LCA" might refer to just the left main, or to the left main and ...
In approximately 33% of individuals, the left coronary artery gives rise to the posterior descending artery [4] which perfuses the posterior and inferior walls of the left ventricle. Sometimes a third branch is formed at the fork between left anterior descending and left circumflex arteries, known as a ramus or intermediate artery .
It is typically a branch of the right coronary artery (70%, known as right dominance). Alternately, the PDA can be a branch of the circumflex coronary artery (10%, known as left dominance) which itself is a branch of the left coronary artery. It can also be supplied by an anastomosis of the left and right coronary artery (20%, known as co ...
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [1]

A myocardial infarction, also known as a heart attack, often result in the formation of fibrosis. [2] A myocardial infarction is an ischemic event, or a restriction of blood flow to body tissue, such as by atherothrombosis. [4] Without blood flow to the myocardium, it is deprived of oxygen, causing tissue death and irreversible damage. [5]
