Temporal flow velocity profile in the descending aorta in coarctation

COARCTATION OF THE AORTA Negligence in Diagnosis Four (Case- Reports).

SUMMARY: Coarctation of the aorta is a congenital heart disease consisting 7% of total congenital heart diseases. Its prevalence in men is 2 times more than that in women. This disease is associated with other congenital diseases. including aortic bicuspid valve, the linkage between two ventricles and arteriole channel It is often seen in the Turner syndrome which may lead to complications su...

Aortic coarctation misdiagnosed as a descending thoracic aorta aneurysm.

Aortic coarctation (AC) represents -7% of congenital cardiac diseases and is usually diagnosed in childhood or early adult Life, depending on the severity of obstruction and associated malformations. Left untreated fewer than 20% of patients survive to age 50. We describe a case of thoracic AC, diagnosed at age 61, in a woman with known hypertension since age 45. At age 56 the patient was admit...

The Renal Blood Flow in Coarctation of the Aorta.

Cerebral Blood Flow in Coarctation of the Aorta.

The hemodynamics of coarctation of the aorta have been extensively investigated. These studies have shown that the renal blood flow is within normal limits (1), as in flow to the extremities (2-4), even though the circulation time to the lower parts of the body has a tendency to be prolonged (5). Although coronary blood flow has been reported to be increased (6), the data are quite scattered, a...

Prediction of Fetal Acidosis by Blood Flow Velocity Waveform of the Fetal Descending Thoracic Aorta

=AbstractZFetal descending thoracic aorta blood flow velocity waveforms were measured in 63 pregnancies. They were either delivered by elective CIS before labor (56 patients) or suffered an antefartum fetal death (7 patients). There was a significant correlation between the aorta waveforms and the cord arterial pH. A cord arterial pH less than 7.20 or an intrauterine fetal death were used as ou...
