PURPOSE: Postcoarctation thoracic aortic aneurysm formation is one of the most serious complications for coarctation of aorta. Open surgery to repair these aneurysms is associated with high morbidity and mortality. Endovascular therapy is an attractive alternative to open surgery. We have studied the efficacy and safety of endovascular therapy for postcoarctation thoracic aortic aneurysms, and will share our findings and experience through this document. METHODS: The data was retrospectively collected on consecutive patients who were presented with postcoarctation thoracic aortic aneurysms at our medical center...

BACKGROUND: There is a high prevalence of late hypertension after coarctation repair. The relative contribution of elevated sympathetic tone and endothelial dysfunction to its development is unknown. This study aims to investigate the neural profile of coarctation patients including muscle sympathetic nerve activity testing to directly measure sympathetic nervous activity. METHODS: Twenty-three patients aged ≥18years with a coarctation repair underwent measurements of clinic and 24-h blood pressures, muscle sympathetic nerve activity, sympathetic and cardiac baroreflex functions, digital endothelial function, and ambulatory arterial stiffness index...

A 200∼240 kb SH2B1-containing deletion region on 16p11.2 is associated with early-onset obesity and developmental delay. Here, we describe monozygotic twin brothers with discordant clinical presentations. Intrauterine fetal growth restriction was present in both twins. Additionally, twin A exhibited coarctation of aorta, left ventricular noncompaction, atrial septal defect, pericardial effusion, left hydronephrosis, and moderate developmental delay, whereas twin B exhibited single umbilical artery. Chromosome microarray analysis was performed on both twins and their parents...

Over the last 15 years, stent placement has become a viable and safe alternative to surgical repair for native and recurrent coarctation of the aorta. Although patients with coarctation of the aorta often have lower exercise tolerance, there is no published data regarding the effect of coarctation stenting on exercise capacity. We aimed to determine the effect of coarctation stent placement on exercise capacity. We conducted a retrospective chart review of all patients who underwent stent placement for native or recurrent coarctation of the aorta at our institution from January 2000 to October 2012...

BACKGROUND: Paradoxical hypertension after repair of coarctation of the aorta is a well-known phenomenon. The pathogenesis involves the activation of the sympathetic nervous system (first phase) and renin-angiotensin system (second phase). Only a limited number of different treatment strategies have been published in the literature, without any comparative studies. METHODS: Our aim was to describe the current international practice variation surrounding pharmacological treatment currently being employed to treat paradoxical hypertension following the repair of coarctation of the aorta in children...

Long-term prostaglandin use is commonly associated with side effects such as cortical proliferation of the bones, hypertrophic pyloric stenosis, and soft tissue swelling of the extremities. We report a neonate with critical coarctation of the aorta, who developed second and third degree atrioventricular blocks associated with prolonged prostaglandin E1 (PGE1) infusion. Interestingly, these conduction blocks only occurred at low PGE1 dose. The rhythm disturbances resolved promptly with the discontinuation of PGE1 following surgical repair...

Coarctation of aorta is a rare congenital malformation and is usually accompanied by other cardiac or vascular lesions. In this case we describe a 51-year-old patient presented with coarctation of the aortic arch and postcoarctation ectasia concomitant with a left subclavian artery aneurysm. Endovascular therapy included the deployment of an inverted wedge-shaped covered stent inserted by a long "chimney" stent and another cylinder-covered stent, forming a "sandwich"-like configuration. The symptoms were alleviated after surgery, and no perioperative or stent-graft-related complications were observed at a 2-year follow-up...

OBJECTIVES: Our goal was to report the selection schemes, technical variations and long-term outcome of extra-anatomical bypass to correct complex, recurrent aortic coarctation and hypoplastic aortic arch. METHODS: Between 1989 and 2012, 53 patients (mean age 13.2 ± 4.3, median 11.6, range 9-23 years) with complex aortic coarctation ( n  = 33; long-segment hypoplastic aortic arch in 15), recurrent coarctation ( n  = 20; anastomosic pseudoaneurysm in 10), underwent correction using extra-anatomical bypass, either with ( n  = 18: femoral bypass = 13, left heart bypass = 5) or without ( n  = 35) extracorporeal circulation via a left lateral thoracotomy ( n = 48) and combined median sternotomy and median laparotomy ( n  = 5)...

We present a case of a 44-year-old woman, with pseudoaneurysm formation at the middle of the prosthetic graft, 60 mm in diameter. She had been diagnosed with atypical coarctation due to aortitis 27 years before, and had undergone a bypass operation with 14 mm-diameter Cooley double velour graft from the ascending aorta to the abdominal aorta. This time, endovascular aortic repair was performed to prevent rupture of the pseudoaneurysm. Though a knitted Dacron graft has a risk of psuedaneurysm formation long patency could be obtained when used in ascending aorta-abdominal aorta bypass...

It was once postulated that open surgical repair of coarctation of the aorta during childhood patients were cured. However, long-term follow up has been significant for late problems such as an aneurysm. The incidence of such aneurysm after open surgical coarctation repair is 11-24%. If such an aneurysm is left untreated, patients are at a high risk of morbidity and mortality. Prior to the endovascular era, patients would require a re-do open repair which in itself is a highly morbid operation. Currently, thoracic endovascular aortic repair (TEVAR) has been reported as a feasible and safe alternative to open surgical re-procedures in this context...

A three-year-old boy was admitted to the children's ward with a newly developed peripheral facial palsy. First examination showed a high blood pressure (BP), but the measurement was initially dismissed as inaccurate. After a few days the boy developed a headache. The BP measurement was replicated, showing 180/120 mmHg, and the boy was treated with antihypertensive medication. Diagnostic imaging showed coarctation of the abdominal aorta and both renal arteries. The boy was finally treated with dilatation of the renal arteries...

A male neonate presented with CHARGE syndrome, a multiorgan genetic disorder involving the Coloboma of the eyes, congenital Heart defects, nasal choanal Atresia, growth and development Retardation, Genitourinary disorders, and Ear anomalies and deafness. Moreover, he had a rare case of vascular ring-consisting of a right aortic arch with retroesophageal brachiocephalic artery-combined with coarctation of the mid-aortic arch. He underwent both vascular ring and aortic arch repair at our institution. To our knowledge, this is the 4th documented case of this exceedingly rare type of aortic arch anomaly combined with aortic arch obstruction...

Objective: Undiagnosed critical congenital heart disease (CCHD) was assessed before discharge from maternity hospital.Basic information was provided for screening CCHD in the early neonatal stage.Chi-squared test was used for comparison of categorical variables(detection rate of different types of CCHD). Method: A retrospective cohort study was conducted in neonates with CCHD who were admitted to Children's Hospital of Fudan University between 1 January 2012 and 31 December 2015. For comparing with the previously reported undiagnosed rate of CCHD at discharge, CCHD was defined as all duct dependent congenital heart disease (DDCHD) and any cyanotic CHD that required early surgery...

Isolated aneurysms of spinal arteries are rare. Spinal artery aneurysms are commonly found in association with spinal cord arteriovenous malformation and coarctation of aorta and rarely with aortic arch interruption and Klippel-Trenaunay syndrome. Spinal angiograms are the gold standard for diagnosing these spinal artery aneurysms but with the advances in computed tomography technology these aneurysms can also be very well demonstrated in computed tomography angiograms. We describe three cases of anterior spinal artery aneurysm, those are flow related aneurysms, associated with coarctation of aorta and with Takayasu arteritis...

BACKGROUND: Coarctation of the aorta (CoA) is difficult to diagnose by fetal echocardiogram (F-Echo), often requiring multiple F-Echos during gestation and neonatal echocardiograms (N-Echos) after birth. Furthermore, CoA is the most common ductal-dependent lesion missed on routine physical exam. OBJECTIVES: We sought to determine the most cost-effective diagnostic approach in caring for infants in whom an initial F-Echo is concerning for CoA. METHODS: Four paradigms for management after initial F-Echo could not rule out CoA were compared, with a single paradigm involving additional F-Echos: (1) multiple F-Echos for diagnostic clarity and performance of N-Echo on neonates with remaining high suspicion for CoA on F-Echos (prenatal-multiple), (2) no further F-Echo and performance of N-Echo on neonates with high suspicion for CoA on initial F-Echo (postnatal-selective), (3) no further F-Echo and performance of N-Echo on all neonates (postnatal-all), and (4) no further F-Echo or N-Echo with reliance on routine physical exam to identify afflicted infants (postnatal-none)...

Coexistence of aortic coarctation with aneurysm of subclavian artery is a uncommon situation and may require unusual treatment in patients. A 40-year-old patient diagnosed incidentally with left subclavian artery aneurysm coexisting with aortic coarctation. Patient was initially referred for hybrid treatment. Initially ostium of the left subclavian artery was covered with a stent-graft. Over a 30-month follow-up period aneurysm became thrombosed all the way up to the ostium of internal mammary artery. The patient did not present with neurological symptoms or signs of upper limb ischemia...

The aim of this study was to explore the clinical impact of transverse aortic arch hypoplasia (TAH) after stent implementation for isthmal coarctation of the aorta (CoA). From a retrospective chart review, 51 children (median age 11.1 years) were identified who had TAH and a CoA stent implanted between 10/1995 and 4/2015. Arm-leg cuff blood pressure measurements, echocardiographic arch imaging, and 24-h ambulatory blood pressure monitoring, prior to and after stent implantation, were reviewed. At catheterization, peak systolic gradients across the CoA's were 25 mmHg before and 4 mmHg after stent implantation...
