Coarctation of the aorta is an important, treatable cause of secondary hypertension. Its prevalence varies from 5% to 8% of all congenital heart defects. This condition is most often detected because of a murmur or hypertension found on routine examination. Delayed or absent femoral pulses and an arm/leg systolic blood pressure difference of 20 mm Hg or more in favor of the arms may be consider...

BACKGROUND Management of an adult patient with aortic coarctation and an associated cardiac pathology poses a great surgical challenge since there are no standard guidelines for the therapy of such complex pathology. Debate exists not only on which lesion should be corrected first, but also upon the type and timing of the procedure. Surgery can be one- or two-staged. Both of these strategies ar...

Background: Aortic coarctation poses a lifelong high cardiovascular risk, despite successful surgical or percutaneous management. Objective: To investigate whether an abnormal aortic function is involved in the higher cardiovascular risk in patients after correction of aortic coarctation. Methods: We recorded aortic pressure waveforms and elastic properties by MRI in 13 patients with normal blo...

Aortic dissection occurs when a tear develops in the wall of the aorta, which is rare in the young population. This fatal disorder is hard to diagnose, especially in young patients. We present the case of aortic dissection in a 15-year-old boy referred to the Emergency Department of Yazd University of Medical Sciences in November 2015. The patient presented to our department with sudden acute c...

Abdominal aortic coarctation is an extremely rare vascular pathology. Its etiology can be congenital or acquired. Here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. She had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. Magnetic reso...

Coarctation of the aorta is usually diagnosed and corrected early in life. Survival to more than 60 years of age of a patient with unrepaired coarctation of the aorta is extremely unusual, and the optimal management strategies for such patients are controversial. We describe the case of a woman who was first diagnosed as having coarctation of the aorta and aortic valve stenosis at the age of 65...

Pulmonary arteriovenous fistula (PAVF) are rare malformations that may cause serious complications such as paradoxical embolism, stroke, pulmonary hemorrhage and hemoptysis. Accompanying cardiac malformations such as aortic coarctation were not reported previously. Here we present a case of complex PAVF associated with aortic coarctation. The patient was treated successfully by transcatheter em...

This study was designed to examine the total body hemodynamics of abdominal aortic coarctation hypertension. The study quantitates both regional and organ blood flow and resistance in conscious rats both above and below an experimentally produced coarctation. The experimental group consisted of 10 male Sprague-Dawley rats with a mean pressure gradient of 68 mm Hg across the coarctation. This ex...

It is well known that about one-third of the patients with Turner's syndrome have coarctation of the aorta; however, only a relatively small number of patients with Turner's syndrome and coarctation of the aorta have been found to also have an aortic aneurysm Patients with Turner's syndrome and aortic aneurysm but without coarctation of the aorta have been documented even less frequently.'" We ...
