    Background & Aim: Coarctation accounts for about 5-9% of congenital heart diseases and is the fifth common congenital heart disorder in children. Approximately 90% of untreated patients die before the age of 50 and about half of deaths occur before the age of 10 due to heart failure. The main goal of this study is assessing the frequency of reccurent coarctation after repair and determining...

background: optimal timing and mode of treatment for patients with coarctation of the aorta ( coa ) remain controversial, particularly in children. surgery, balloon dilatation, and stent implantation have all proven effective in the treatment of moderate or severe obstruction. the aim of this study was to investigate the complications of coa stenting angioplasty in pediatric patients. methods: ...

OBJECTIVE To investigate the incidence of clinical problems related to a bicuspid valve (aortic stenosis and regurgitation) and the incidence of ascending aorta and aortic arch pathology in combination with coarctation repair. PATIENTS 124 adult patients after surgical correction of aortic coarctation were studied. The incidence of aortic valve, ascending aorta, and aortic arch pathology was ...

Balloon angioplasty for coarctation of the aorta was performed in 45 patients; 17 (Group 1) were infants (mean age 34 + 43 days). This study focuses on the remaining 28 patients (Group 2), children and adults ranging in age from 2 to 31 years (mean 13 f 8). Two patients had had previous surgery for coarctation; in the remaining 26 the coarctation had not been surgically treated. Twenty patients...

We studied baroreceptor function in dogs before and after surgical repair of coarctation of the aorta by direct recording of multifiber carotid sinus (CS) nerve activity (NA) during alteration of pulsatile arterial pressure with systemic phenylephrine and nitroprusside, and during static pressure changes using a CS pouch preparation. Coarctation was induced by banding the proximal thoracic aort...

INTRODUCTION Coarctation of aorta is the fourth most common cardiac lesion requiring intervention. While surgery used to be the only treatment option, endovascular intervention is now considered the first option in simple coarctation lesions. Despite increased popularity, there are currently no FDA approved stents for use in coarctation of aorta and data on the outcome of this procedure is stil...

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...

In a prospective echocardiographic study of over 2000 pregnancies, 24 fetuses were found to have dilatation of the right ventricle and pulmonary artery when these structures were compared with those of the left heart. In 18 of these cases the diagnosis of coarctation or interruption of the aorta was correctly inferred from these findings. On direct echocardiographic examination of the aortic ar...

•Here, we are presenting a very rare case of coarctation of abdominal aorta where a transcatheter closure by a vascular plug of the feeding collateral to a large aneurysm has been done. To the best of our knowledge, this mode of therapy has never been described in persons with coarctation of abdominal aorta.•Aneurysms in patients with an abdominal coarctation are not well recognized. This is pr...

Balloon dilation angioplasty (BDA) was attempted nine times in eight infants and children with aortic coarctation. In three infants (all with associated ventricular septal defect or atrioventricular canal and marked hemodynamic instability) dilation was attempted at a site of aortic narrowing that had not been operated on previously. Although the coarctation gradient fell 40% or more over the s...
