What Does The Aorta Do In The Heart
Lots: I'm not sure what exactly you're referring to, but the typical valve with two leaflets is the mitral valve. It's usually not called "the bicuspid valve" though. A bicuspid aortic valve is a 2 leaflet aortic valve (should be 3) and is the most common congenital abnormality which can lead to aortic valve leaking or tightness later in life. ...Read moreSee 1 more doctor answer
Abnormal embryology: By definition coarctation of the aorta is a abnormality of vascular embryology. At birth flow is adequate for the limited activity i the new born and early toddler years, but as children age, their growing bodies and activity out grows the narrowed aorta's ability to supply enough blood fast enough to keep up. ...Read more

Not in the heart: Coarctation of aorta by definition does not occur in the heart. It is usually in the descending segment of the aorta and it is congenital (person is born with it). The exact location is variable, sometimes it involves the aorta proximal to the take off of the left subcalvian (artery to the left arm) and at times distal to it. It is essentially a narrowing of the lumen of the artery. ...Read moreSee 2 more doctor answers

Bypass channels: The fetus/baby developed & is more or less normal in appearance at birth.That would only occur with the bodies ability to bypass the narrowing of a coarctation by channeling needed blood flow though other blood vessels(collaterals). A kid may go for a few years before the coarctation is discovered. ...Read moreSee 1 more doctor answer
PDA: It occurs between descending thoracic aorta and PA. The descending thor aorta is well to the left of the right branch of the PA. I couldn't find a variant reported in the literature with involvement of the right PA branch. There may be an embryologic explanation but I didn't find it. ...Read more
Deposits cholesterol: Atherosclerosis occurs when cholesterol deposits called plaque form in the wall of your arteries. If the plaque gets big enough it can block flow of blood causing injury to the tissue that was supplied by the artery. That is how heart attacks, strokes, leg ulcers, etc occur. ...Read moreSee 2 more doctor answers
Improves blood flow: Bypass surgery is done for blockages in the heart arteries. Essentially we add more blood vessels to the heart to deliver blood to the areas blocked off. We go around the blockages (bypass). We're plumbers :). We put new pipe in by hooking up before and after the blockages. Unfortunately i can't go to home depot and buy pipe so we get it from veins in legs and arteries from breast bone and arms. ...Read moreSee 1 more doctor answer
See below: The mitral valve regulates the inflow of the heart into the left ventricle and regulates the flow between the high chamber of the heart (atrium) and the low chamber of the heart (ventricle) on the left side. And it prevents the blood from going back into the lungs on the left side. ...Read moreSee 1 more doctor answer
When doing duplex of the carotid arteries, how high up the neck do u see? Where does the sight usually end? Can u see in level with the cheekbones?
Usually up to: the area where the arteries enter the skull. So, no, it does not image the area of cheekbones. It is useful test because atherosclerotic carotid disease is very common where common carotid artery bifurcates into external and internal branches. ...Read more
