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...

BACKGROUND The purpose of this study was to evaluate the utility of multi-detector computed tomography (MDCT) angiography and transthoracic echocardiography (TTE) in the diagnosis of congenital coarctation of the aorta (CoA) and accompanying malformations in infants. MATERIAL AND METHODS From January 2012 and December 2015, we enrolled 68 infants with clinically suspected CoA who underwent MDCT angiography and TTE in our hospital. Surgical correction was conducted to confirm the diagnostic accuracy of both examinations in all patients...

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: We aimed to assess the results of various tailored management strategies for adults with coarctation in our centre. METHODS: : We reviewed all adults patients treated for aortic caorctation between January 2000 and December 2015 in our institution. The primary end point was a composite of death, perioperative stroke, paraplegia, need for unplanned reoperation or occurrence of pseudoaneurysm during the follow-up. The mean follow-up was 82 ± 5 months...

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...

Knowledge of aortic growth in patients with bicuspid aortic valve (BAV) is essential to identify patients at risk for dissection, but data on children remain unclear. We retrospectively evaluated the aortic diameters of all pediatric BAV patients, identified through an echocardiographic database (2005 to 2013). Medical records were reviewed and aortic diameters re-measured on echocardiographic images at diagnosis and if available on variable mid- and endpoints follow-up. Dilatation (z-score >2) was based on 2 different z-score equation methods (Gautier/Campens)...

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...

BACKGROUND: neonatal cardiac surgery has evolved over the last 50 years with a large percentage of the patients achieving complete physiological repair in the neonatal period. The remaining patients achieve staged palliation with an increasing amount of success. OBJECTIVES: To report our experience with 1000 neonatal cardiac surgical procedures performed in the last 10 years. METHODS: We conducted a retrospective analysis of surgical outcome in all neonatal patients who underwent cardiac surgery between January 2007 and July 2016 at Schneider Children's Medical Center of Israel...
