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 ...
Most commonly, the left internal thoracic artery (LITA; formerly, left internal mammary artery, LIMA) is anastomosed to the left anterior descending artery (LAD) because the LAD is the most significant artery of the heart and supplies blood to a larger portion of myocardium than other arteries. [21]
Dual anti-platelet therapy and full anticoagulation are currently under investigation. The primary etiology of coronary ectasia in adults is atherosclerosis, thus treatment with statin therapy should be considered. Statin therapy may also reduce inflammation and matrix metalloproteinase activation which may reduce the progression of vessel ectasia.
In normal anatomy, three essential coronary arteries are identified: right coronary artery (RCA), left anterior descending artery (LAD) and left circumflex artery (LCx). LAD and LCx usually originate from the bifurcation of a common vessel known as left main trunk or left coronary artery (LM or LCA). [citation needed]
Coronary angiography and angioplasty in acute myocardial infarction (left: RCA closed, right: RCA successfully dilated) Tight, critical stenosis (95%) of the proximal LAD in a patient with Wellens' warning Stent placement. A, the catheter/DES device is inserted across the lesion.
Wellens' syndrome is an electrocardiographic manifestation of critical proximal left anterior descending (LAD) coronary artery stenosis in people with unstable angina. Originally thought of as two separate types, A and B, it is now considered an evolving wave form, initially of biphasic T wave inversions and later becoming symmetrical, often ...
The left coronary artery arises from the aorta within the left cusp of the aortic valve and feeds blood to the left side of the heart. It branches into two arteries, the left anterior descending and the left circumflex. The left anterior descending artery perfuses the interventricular septum and anterior wall of the left ventricle. The left ...
[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 ...
