Central aortic pressure (CAP), central aortic blood pressure (CABP), or central aortic systolic pressure (CASP) is the blood pressure at the root of aorta.Studies have shown the importance of central aortic pressure, especially as compared to peripheral blood pressure, and its implications in assessing the efficacy of antihypertensive treatment with respect to cardiovascular risk factors ...
There are two forms of aortic coarctation to be familiar with, an “infant” form and an “adult” form. With the infant form, which accounts for about 70% of cases, the coarctation comes after the aortic arch, which branches off to the upper extremities and to the head, and before the ductus arteriosus.
The severity of coarctation of the aorta can be rated by a combination of the smallest aortic cross-sectional area of the aorta (adjusted for body surface area) as measured by 3D-rendered contrast MRI, as well as mean heart rate–corrected flow deceleration in the descending aorta as measured by phase contrast magnetic resonance imaging.
In the early 1950s, Twitchell began studying the pattern of recovery in stroke patients. He reported on 121 patients whom he had observed. He found that by four weeks, if there is some recovery of hand function, there is a 70% chance of making a full or good recovery.
An aortic coarctation is a narrowing of the aorta, which is split into infant and adult forms. In the infant form, it's often accompanied by patent ductus arteriosus, and mixing of deoxygenated and oxygenated blood, whereas in the adult form, the ductus arteriosus has closed off.
As the blood moves into the aortic arch, the area with the highest velocity tends to be on the inner wall. Helical flow within the ascending aorta and aortic arch help to reduce flow stagnation and increase oxygen transport. [4] As the blood moves into the descending aorta, rotations in the flow are less present.
An aortic cross-clamp is a surgical instrument used in cardiac surgery to clamp the aorta and separate the systemic circulation from the outflow of the heart. [ 1 ] An aortic cross-clamping procedure serves, for example, in the repairing of coarctation of the aorta.
