coronary artery

n.

1. An artery with origin in the right aortic sinus; with distribution to the right side of the heart in the coronary sulcus, and with branches to the right atrium and ventricle, including the atrioventricular branches and posterior interventricular branch; right coronary artery.

2. An artery with its origin in the left aortic sinus; with distribution into two major branches, the anterior interventricular, which descends in the anterior interventricular sulcus, and the circumflex branch, which passes to the diaphragmatic surface of the left ventricle, and with the atrial, ventricular, and atrioventricular branches; left coronary artery.

coronary artery,

one of a pair of arteries that branch from the aorta, including the left and the right coronary arteries. Because these vessels and their branches supply the heart, any dysfunction or disease that affects them can cause serious, sometimes fatal complications. Coronary arterial anastomoses occur throughout the heart and are especially numerous within the interventricular and interatrial septa, at the apex of the heart, at the crux, over the anterior surface of the right ventricle, and between the sinus-node artery and the other atrial arteries. These anastomoses are more numerous and larger in the epicardium than in the endocardium, and they provide important collateral circulation in the recovery of patients who suffer coronary occlusions. The branches of the coronary arteries are affected by many different disorders, such as embolic, neoplastic, inflammatory, and noninflammatory diseases.

Patient discussion about coronary artery.

Q. my mother have stem replacement for a coronary artery oclusion is already 2 years she physically deteriorating since surgery why???? please help she does not have energy

A. I agree with Dagmar. It can be most likely caused by another occlusion or re-occlusion inside the heart blood vessels. Since that is a life-threatening case, I strongly suggest you to bring your mother into a hospital (for complete check up), or just call your cardiologist to have first treatment.

Meanwhile, that will be better if you have emergency oxygen (just in case you'll need it) with you.
