the most commonly encountered congenital heart diseases, presenting either in isolation or in association with other cardiac defects. It comprises approximately 5-8% of all congenital heart defects and in the majority of cases it is diagnosed and treated during childhood. Aortic coarctation presenting during adult life most frequently represents cases of re-coarctation, following previous trans...

Coarctation of the aorta is a congenital heart disease defined as an obstruction of the aorta distal to the left subclavian artery (between the aortic arch and descending aorta). It is usually associated with other diseases such as bicuspid and tricuspid aortic stenosis. If the coarctation remains uncorrected it can lead to hypertension, left ventricular failure and aortic dissection. Numerous ...

The objective of the present study was to determine the contribution of the sympathetic nervous system to the hypertensive response to acute (45-min) aortic coarctation in conscious intact or sinoaortic-denervated (SAD) rats. Rats were treated chronically (5 wk) with guanethidine (50 mg ⋅ kg-1 ⋅ day-1ip) to induce sympathetic nerve degeneration or acutely with the α1-adrenergic receptor antagon...

OBJECTIVES To validate ascending aorta-lower abdominal aorta bypass grafting treatment for patients with descending aortic coarctation and an aortic valve disease. METHODS The three patients in whom a descending atypical aortic coarctation was associated with an aortic valve disease were treated with one stage surgical treatment with aortic bypass grafting through the diaphragm and aortic val...

BACKGROUND Coarctation of the aorta in the adulthood is sometimes associated with additional cardiovascular pathologies that require intervention. Ideal approach in such patients is uncertain. Anatomic left-sided short aortic bypass from the arcus aorta to descending aorta via median sternotomy allows simultaneous repair of both complex aortic coarctation and concomitant cardiac operation. MA...

The combination of right aortic arch with aberrant left brachiocephalic artery and aortic coarctation is very rare. Here, we report the case of a 3.1-kg neonate with multiple malformations who received detailed preoperative anatomical definition by chest computed tomography (CT) scan and eventually underwent one-stage repair at the age of 17 days. The surgical technique included left brachiocep...

This communication describes and discusses the results obtained in studying central and )eripheral arterial pressure pulses in man by means of retrograde aortic catheterization. The pressure pulse transformation and pulse transmission in the aorticobrachial system are presented and compared with comparable tracings reported in the dog. Several normal subjects and patients with hypertension, aor...

Aortic coarctation is one of the most frequently observed congenital cardiac diseases and has been defined as a stenosis in a segment of the aorta (1). This stenosis is just distal to where the left subclavian artery branches off, and right across from the insertion of ductus arteriosus to the aorta in 98% of cases (2). The incidence of aortic coarctation is 1/2500 live births, and is seen twic...

Among 119 cases of fatal dissecting aneurysm of the aorta, exclusive of those iatrogenically caused or associated with arachnodactyly or aortic stenosis, there were observed 11 cases of congenital bicuspid aortic valve (9%). The ages ranged from 17 to 69 years, five of the patients being 29 years old or younger. Among the latter, three had coarctation of the aorta and one had Turner's syndrome ...
