Late complications after surgical repair of aortic coarctation are not uncommon. Among these complications pseudoaneurysms are the most frequent complications, occurring between 3 and 38%. Reoperation in these patients is associated with high morbidity and mortality. In the last decade, endovascular techniques emerged as an alternative to conventional surgery with excellent results. We report t...

Restenosis rarely develops after surgical correction of coarctation of the aorta in adults. Late morbidity is usually related to residual hypertension or progressive aortic valve disease. A patient in whom symptoms and signs of recurrent coarctation developed 19 years after initial graft repair is described. Dehiscence of the original silk suture line was found at operation. Extensive thrombus ...

PURPOSE To show that 4D Flow is a clinically viable tool for evaluation of collateral blood flow and demonstration of distorted blood flow patterns in patients with treated and untreated aortic coarctation. MATERIALS AND METHODS Time-resolved, 3D phase contrast magnetic resonance imaging (MRI) (4D Flow) was used to assess blood flow in the thoracic aorta of 34 individuals: 26 patients with co...

Real-time cross-sectional echocardiographic sector scan examinations were performed from a suprasternal notch location to image aortic anatomy in 15 children (ages 1 day to 21 years) who were subsequently shown at cardiac catheterization to have coarctation of the descending thoracic aorta. The resulting echocardiographic images of the ascending, transverse and descending aorta imaged juxtaduct...

To establish an integrated non-invasive method for diagnosing coarctation, cross-sectional echocardiographic appearances of 48 neonates and infants with coarctation were combined with clinical information on the peripheral pulses. Measurements of the ascending aorta, aortic arch, and isthmus were made and compared with those from controls matched for weight and age. Confirmation of the coarctat...

Atypical locations for aortic coarctation have been previously described. However, to our knowledge, no case has been described of a rapidly progressive dilated cardiomyopathy caused by an atypical coarctation, with a rapid normalisation of ventricular function after treatment.

Flow of a blood analog is modeled through a patient-specific aortic coarctation using ANSYS Fluent software. Details of the patient data (aortic geometry and prescribed flow conditions) were provided by the MICCAI-STACOM CFD Challenge website. The objective is to predict a blood pressure difference across the rigid coarctation under both rest and exercise (stress) conditions. The supplied STL g...

In eight humans with coarctation, fresh aortic tissue was examined pharmacodynamically. In four of these patients, and in 12 additional patients, the aorta above and below the coarctation was studied morphologically and compared with eight control aortas. By in vitro stimulation with potassium (127 mM), noradrenaline (18 usM), and prostaglandin F,. (28 M), postcoarctational aortic ring preparat...

BACKGROUND Partial anomalous pulmonary venous connection (PAPVC) without an atrial septal defect (ASD) associated with coarctation of the aortic arch is a rare congenital cardiac anomaly. This rare combination is only described in a few studies; none report the correction of these two malformations in a single surgery. CASE PRESENTATION A 5-year-old girl was admitted to our hospital because t...

Coarctation of the aorta is a common congenital defect, which although normally detected and surgically repaired in childhood may present in adolescence or adulthood, usually in the context of investigation for hypertension. The morphological spectrum of abnormalities range from a discrete stenosis distal to the left subclavian, often with extensive collateral formation, to a hypoplastic transv...
