Background: Aortic coarctation is a congenital narrowing of the aorta. Computed tomography angiography is used to detect aortic coarctation and determine its extent and severity. Objective: To assess pediatric aortic coarctation by computed tomography (CT) angiography. Material and Methods: This study included eighteen patients (10 males and 8 females) who were clinically diagnosed to have coar...

We investigated the role of vasopressin, angiotensin II, and catecholamines in the onset of acute (45-minute) aortic coarctation hypertension in conscious rats. Partial aortic constriction was performed by means of a pneumatic cuff placed around the abdominal aorta above the renal arteries for 15 or 45 minutes. A sham-operated group was used as control. Mean carotid pressure before aortic const...

Survival to advanced age is exceptional in patients with unrepaired aortic coarctation. We report the case of an 81-year-old man with aortic coarctation and total occlusion who was otherwise asymptomatic. Coarctation was suspected when a femoral-radial pulse delay was noted during his routine physical examination. A 70-mmHg systolic blood pressure gradient between the upper and lower extremitie...

Double orifice mitral valve is a rare congenital anomaly presenting as the division of the mitral orifice into two anatomically distinct orifices, it is most often associated with other congenital heart defects such as left-sided obstructive lesions, ventricular septal defects or aortic coarctation. We report the case of a 15 year's old boy, admitted for arterial hypertension, auscultation reve...

Background Aortic Coarcatation (CoA) is one of the congenital heart diseases with the rate of 5-8% of Coronary heart diseases(CHDs). Balloon angioplasty is now one of the effective way of treatment for CoA, native or Re-coarctation (Re-CoA). We aimed to assess the immediate, and short term response to angioplasty and stenting, and also complications. Materials and Methods Balloon angioplasty wi...

Pseudoaneurysm is an infrequent complication of aortic coarctation repair. It occurs in 5-9% patients. Further complications such as pseudoaneurysm rupture or aorto-pulmonary fistula (APF) carry a high mortality rate and represent therapeutical.

Balloon angioplasty as treatment for coarctation of the aorta is increasingly performed. Endovascular stents have been proposed as a means of improving the efficacy and safety of the procedure. In this report, we describe one institution's immediate results and clinical follow-up after implantation of endovascular stents. Retrospective analysis for endovascular stent placement for coarctation o...

Nineteen infants with suspected coarctation of the aorta were studied with electrocardiographically gated magnetic resonance imaging on a 1.5 T whole body imaging system. In all cases imaging was successful and produced diagnostic images of high resolution. Coarctation was shown in 12 cases. The position and shape of the coarctation were well displayed by the magnetic resonance images. In addit...

BACKGROUND Although balloon angioplasty (BA) has been performed for more than 20 years, its use as a treatment for native coarctation of the aorta (CoA) during childhood, especially in young infants, remains controversial. This study aimed to assess the effects and potential role of percutaneous transcatheter BA for native CoA as an alternative therapy to surgical repair in young infants. MET...

BACKGROUND The mechanism of the late complications after coarctation repair remains unclear, and this common congenital heart disease affects patients and perplexes physicians in terms of prevention and treatment. METHODS From 2004 to 2008, 13 patients (1 adolescent and 12 adults) with repaired or unrepaired coarctation of the aorta were operated on in this department due to valve disorder or...
