aortic arch syndrome any of a group of disorders adding to occlusion of the arteries arising from the aortic arch; such occlusion may be caused by atherosclerosis, arterial embolism, or other conditions. See also pulseless disease.
aortic septal defect a congenital anomaly in which there is abnormal communication between the ascending aorta and the pulmonary artery just above the semilunar valves.

MAIN PARTS OF AORTA
The main trunk of the arterial system of the body. aortic (ā-or′tĭk), adjective

The aorta is about 3 cm in diameter at its origin in the upper surface of the left ventricle. It passes upward as the ascending aorta, turns backward and to the left (arch of the aorta) at about the level of the fourth thoracic vertebra, and then passes downward as the thoracic aorta to the diaphragm, and below the diaphragm as the abdominal aorta. The latter terminates at its division into the two common iliac arteries. At the junction of the aorta and the left ventricle is the aortic semilunar valve, which contains three cusps. This valve opens when the ventricle contracts and is closed by the backup of blood when the ventricle relaxes. See: illustration

The divisions of the aorta are as follows:

Ascending aorta (two branches): Two coronary arteries (right and left) provide blood supply to the myocardium.

Aortic arch (three branches): The brachiocephalic artery divides into the right subclavian artery, which provides blood to the right arm and other areas, and right common carotid artery, which supplies the right side of the head and neck. The left common carotid artery supplies the left side of the head and neck. The left subclavian artery provides blood for the left arm and portion of the thoracic area.

Thoracic aorta: Two or more bronchial arteries provide blood for bronchi. Esophageal arteries provide blood to the esophagus. Pericardial arteries supply the pericardium. Nine pairs of intercostal arteries supply blood for intercostal areas. Mediastinal branches supply lymph glands and the posterior mediastinum. Superior phrenic arteries supply the diaphragm.

Abdominal aorta: The celiac artery supplies the stomach, liver, and spleen. The superior mesenteric artery supplies all of the small intestine except the superior portion of the duodenum. The inferior mesenteric artery supplies all of the colon and rectum except the right half of the transverse colon. The middle suprarenal branches supply the adrenal (suprarenal) glands. The renal arteries supply the kidneys, ureters, and adrenals. The testicular arteries supply the testicles and ureter. The ovarian arteries (which correspond to internal spermatic arteries of the male) supply the ovaries, part of the ureters, and the uterine tubes. The inferior phrenic arteries supply the diaphragm and esophagus. The lumbar arteries supply the lumbar and psoas muscles and part of the abdominal wall musculature. The middle sacral artery supplies the sacrum and coccyx. The right and left common iliac arteries supply the lower pelvic and abdominal areas and the lower extremities.

Patient discussion about aortic

Q. Why does Aortic stenosis causes an enlarged heart? My father was recently diagnosed as suffering from enlarged heart due to his Aortic stenosis. what is the connection between those to conditions? As far as I understand that aortic stenosis mean that the aortic valve is too small not too large...

A. there are several explanations for the enlargement of the heart that occurs due to Aortic stenosis. the most reasonable is that the mechanical power that the heart uses makes it bigger. it easy to see it here: http://www.marvistavet.com/assets/images/aortic_stenosis.gif
this is called Left Ventricular Hypertrophy or LVH in abbreviations.
this is a classic LVH E.C.G.

Q. How does alcohol affect someone who has been diagnosed with aortic valve stenosis? My brother has been diagnosed with aortic valve stenosis and also is a smoker and does drink alcohol on the weekends. He knows that he should stop smoking but what about the effects of alcohol? Does this also contribute to his stenosis?

A. Alcohol changes blood pressure and speed of the heart- that is not a good idea if you have an Aortic stenosis. Could probably makes things worst. I would avoid alcohol… but he should ask GP.

Q. Is there a good screening test for aortic abdominal aneurysm? A friend of mine was diagnosed with an aortic abdominal aneurysm. I am afraid i might have this condition too. is there any screening test that is good for me?

A. Today there are "mobile" testing centers that charge to use ultrasound technology to detect such things as AAA. I would highly recommend it only because it can act as a preventative measure. I am 50 years old and just suffered a ruptured AAA that very nearly killed me. I was the fortunate one. This very possibly could have detected it before it actually ruptured. You may want to check in your local areas for these mobile testing centers.
