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: 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...

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...

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...

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...

Transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valves has been successfully performed, but there is a lack of published experience in percutaneous treatment of patients with unicuspid valves and severe aortic stenosis. We describe a case of TAVR in such a patient. A 31-year-old woman with Turner syndrome-who had undergone coarctation repair via subclavian flap at age 7 days and an aortic valvotomy at age 6 weeks-presented with severe symptomatic aortic stenosis. She was deemed inoperable because of her severe pulmonary hypertension and numerous comorbidities; consequently, a 20-mm Edwards Sapien 3 Transcatheter Heart Valve was offered for compassionate use...

Persistent left fifth aortic arch is a rare anomaly often associated with aortic coarctation. We report the case of a newborn presenting with signs of duct-dependent aortic coarctation. Echocardiography showed an interrupted fourth aortic arch, persistent left fifth aortic arch associated with aortic coarctation, and a restrictive arterial duct. Arch repair was accomplished using the fifth aortic arch as an in situ flap to enlarge the hypoplastic fourth aortic arch associated with coarctectomy and extended end-to-end anastomosis...

BACKGROUND: Undesirable outcomes in health care are associated with patient harm and substantial excess costs. Coarctation of the aorta (CoA), one of the most common congenital heart diseases, can be repaired with stenting but requires monitoring and subsequent interventions to detect and treat disease recurrence and aortic wall injuries. Avoidable costs associated with stenting in patients with CoA are unknown. METHODS: We developed an economic model to calculate potentially avoidable costs in stenting treatment of CoA in the United Kingdom over 5 years...

A 5-day-old neonate with coarctation of the aorta, hypoplastic aortic arch, large apical muscular ventricular septal defect, and patent ductus arteriosus developed pulmonary over-circulation and systemic hypoperfusion underwent bilateral pulmonary artery banding through median sternotomy as a part of hybrid stage I palliation. At operation, left atrial diverticulum with gigantic thrombus formation at the base of the left atrial appendage was incidentally detected by intraoperative direct echocardiography, and therefore, was successfully resected with the whole thrombus inside it without use of cardiopulmonary bypass...

The strategy for an infant with congenital mitral stenosis should be determined by three important factors: left ventricular volume, the degree of the systemic outflow tract obstruction, and the type of mitral valve dysfunction. A successful staged biventricular repair in early infancy for a patient who had congenital mitral stenosis with short chordae, hypoplastic left ventricle and coarctation of the aorta, and the long-term results are described. There were the following important hemodynamic factors that led to the successful biventricular repair in the patient...

Hybrid surgery is becoming more popular in the treatment of children with congenital heart disease, particularly small infants and neonates. We report a case of a patient with aortic stenosis (AS) and coarctation of the aorta (CoA). CASE: a 1-month-old baby presented with severe AS and CoA. The decision was made to perform a hybrid surgical procedure. The patient underwent a lateral thoracotomy for repair of the CoA and carotid cutdown for aortic balloon valvuloplasty (AoVP).

BACKGROUND: Computed tomographic angiography (CTA) and echocardiography (echo) are used preoperatively in coarctation of the aorta to define arch hypoplasia and great vessel branching. We sought to determine differences in quantitative measurements, as well as surgical utility, between modalities. METHODS: Infants (less than six months) with both CTA and echo prior to coarctation repair from 2004 to 2013 were included. Measurements were compared and correlated with surgical approach...

Ventricular septal defect and aortic arch obstruction are usually associated with a narrow left ventricular outflow tract. The aim of the present study was to analyse the growth and predictors of future obstruction of the left ventricular outflow tract after surgical repair. METHODS: We carried out a retrospective review of patients who underwent repair for ventricular septal defect and aortic arch obstruction - coarctation or interrupted aortic arch - between July, 2002 and June, 2013...

BACKGROUND: Pulse wave velocity (PWV) is a biomarker for the intrinsic stiffness of the aortic wall, and has been shown to be predictive for cardiovascular events. It can be assessed using cardiovascular magnetic resonance (CMR) from the delay between phase-contrast flow waveforms at two or more locations in the aorta, and the distance on CMR images between those locations. This study aimed to investigate the impact of different distance measurement methods on PWV. We present and evaluate an algorithm for automated centreline tracking in 3D images, and compare PWV calculations using distances derived from 3D images to those obtained from a conventional 2D oblique-sagittal image of the aorta...

The treatment of choice for aortic coarctation in adults remains open surgical repair. Aortobronchial fistula is a rare but potentially fatal late sequela of surgical correction of isthmic aortic coarctation via the interposition of a graft. The endovascular treatment of aortobronchial fistula is still under discussion because of its high risk for infection, especially if the patient has a history of cardiovascular prosthetic implantation. Patients need close monitoring, most notably those with secondary aortobronchial fistula...
