Abstract
Congenital heart disease (CHD) is a structural abnormality of the heart and/or great vessels and patients with CHD are at an increased risks of various morbidities throughout their lives and reduced long-term survival. Eventually, CHD may result in various complications including heart failure, arrhythmias, stroke, pneumonia, and sudden death. Unfortunately, the exact etiology and pathophysiology of some CHD remain unclear. Although the quality of life and prognosis of patients with CHD have significantly improved following technological advancement, the influence of CHD is lifelong, especially in patients with complicated CHD. Thus, the management of CHD remains a challenge due to its high prevalence. Finally, there are some disagreements on CHD among international guidelines. In this review, we provide an update of the pathophysiology, diagnosis, and treatment in most common type of CHD, including patent foramen ovale, atrial septal defect, ventricular septal defect, atrioventricular septal defect, patent ductus arteriosus, coarctation of the aorta, transposition of the great arteries, congenitally corrected transposition of the great arteries, coronary anomalies, left and right ventricular outflow tract obstruction, tetralogy of Fallot and Ebstein anomaly. In particular, we focus on what is known and what is unknown in these areas, aiming to improve the current understanding of various types of CHD.

Abstract
The present study aimed to evaluate the outcomes of percutaneous treatment of aortic coarctation using self-expandable uncovered Nitinol stents. We conducted a retrospective clinical data review of all patients with aortic coarctation and treated with self-expandable uncovered Nitinol stents at our institution between 2009 and 2019. The gradient pressure across the coarctation site was measured using aortography. Follow-up echocardiography and computed tomography angiography were performed to assess possible stent complications. A total of 127 stents were successfully implanted in 125 patients (64.8% males) with a mean age of 35.36 ± 11.9 years. The gradient across the coarctation site decreased significantly from 67.48 ± 14.79 to 5.04 ± 3.01 mmHg (P < 0.001) after self-expandable stent implantation. Systolic blood pressure (SBP) decreased significantly from 175.53 ± 15.99 to 147.22 ± 12.83 mmHg (P < 0.001) after self-expandable stenting. There were no major technical or clinical complications, including balloon rupture, aneurysmal formation, infection, secondary stent migration, thrombosis, death during the procedure, and in-hospital mortality. On a mean follow-up of 48 ± 23.6 months (12-120 months), the gradient [from 59.43 ± 15.42 to 3.72 ± 1.38 mmHg (P < 0.001)] and SBP [from 175.53 ± 15.99 to 127.99 ± 7.82 mmHg (P < 0.001)] decreased significantly. There was no mortality, aneurysmal formation in the stent site, dislocation, or aortic re-stenosis requiring intervention during mid-term follow-up. Treatment of aortic coarctation using a self-expandable uncovered nitinol stent is safe and effective with promising mid-term outcomes.

Abstract
While coarctation of the aorta varies greatly in both severity and age at presentation, all patients are at increased risk of hypertension both before and after repair. Despite advances in knowledge about genetic etiologies, pathophysiologic mechanisms, and optimal repair strategies, patients with repaired coarctation of the aorta remain at increased risk of acquired cardiovascular disease. The aims of this review are to describe the management of coarctation of the aorta at all ages before and after repair, highlight pathophysiologic mechanisms of hypertension, and review long-term follow-up considerations.

Abstract
BACKGROUND/PURPOSE CoA remains one of the most common congenital heart diseases and is associated with significant morbidity and mortality and if untreated. We aim to evaluate the safety, feasibility, and outcomes of endovascular stenting of Coarctation of the aorta (CoA) in a developing country with limited resources and compare it to available benchmarks. MATERIALS/METHODS A retrospectively review of all patients who underwent endovascular stent repair of aortic coarctation at our tertiary center since 2009 was done. RESULTS 18 patients were identified, sixteen had native CoA, while two had recurrent CoA. mean age at the time of procedure was 21.2 ± 9.8 years (range 10-45 years), and 12(66%) patients were males. The mean follow-up duration was 4 ± 2.8 years. Post stenting, the average ascending-to-descending aorta systolic gradient decreased by 42.9 ± 20.4 mmHg (p < 0.001). After the intervention, 13(72.2%) patients achieved normal BP while 5(27.8%) had residual hypertension. Fourteen patients received bare-metal stents, and four had covered stents. Attempted stent implantation was successful in all patients. Our procedural success rate was 94%. On follow-up, no dissections or aneurysmal changes were detected, four patients underwent re-expansion of the stent, one patient with suboptimal stenting result required surgery 6 months after stenting, and two patients had minor post-operative complications. CONCLUSIONS Endovascular stenting for de-novo or recurrent CoA in children and adults at a tertiary center in a developing country is feasible and safe with outcomes comparable to developed countries. A multidisciplinary team approach is paramount in achieving good results and low complication rates in limited-resource settings.

Abstract
BACKGROUND Persistence or recurrence of stenosis is a complication of initial coarctation repair. This study aims to report short-term outcomes of surgical management of recurrent coarctation and initial repair analysis. METHODS We retrospectively reviewed our experience with 51 patients undergoing recoarctation surgical repair between 2008 and 2019 using antegrade cerebral perfusion (ACP) technique. RESULTS Surgical correction included prosthetic patch aortoplasty in 23 (45%), resection with wide end-to-end anastomosis in 15 (29%), and a tube interposition graft in 13 (25%) patients. The median age at initial correction and reintervention was 12 months and 9 years. The median interval from primary repair to reintervention was 60 months. Initial repair analysis revealed 33% of patients had initial correction in the neonatal period, 72.5% of patients were done via a left thoracotomy approach and 63% of patients had end-to-end anastomosis at initial surgery. CONCLUSION Our study demonstrates that surgical repair of recurrent coarctation of the aorta using ACP technique can be performed safely and with excellent results.

Abstract
AIMS The aim of this study was to report our experience with the Cook Formula stent in the treatment of (recurrent) coarctation of the aorta in children below 12 kg. METHODS AND RESULTS In vitro study of the Cook Formula 418 (8 mm) and 535 (8 and 10 mm) stents demonstrated successful down-crimping on smaller balloons and predictable fracturing patterns. Between November 2012 and January 2019, one patient with native, one patient with post-interventional and thirteen patients with post-surgical coarctation of the aorta underwent implantation of a Cook Formula stent. Patient and procedural characteristics were obtained as well as procedural success, complications, and follow-up. Median age was 4.3 months and median weight 5.5 kg. Arterial sheath size ranged from 5 to 7 Fr. In-stent diameters of 3.7 to 8.8 mm were obtained with a median residual gradient of 0 mmHg. Major complications consisted of periprocedural haemodynamic instability (n=1), dissection of the iliac artery (n=1) and non-deployment with surgical removal (n=1). Re-dilations were performed after a median interval of 24.3 months. Median follow-up was 31.7 months. CONCLUSIONS The bare metal Cook Formula stent provides a durable and effective alternative to reoperation and balloon dilatation for native as well as post-surgical aortic coarctation in children below 12 kg.

Abstract
BACKGROUND Balloon angioplasty for native coarctation of the aorta (CoA) is successful in children and adults but in neonates results in frequent restenosis. The efficacy of balloon angioplasty for native CoA during infancy beyond the neonatal period was examined in infants aged 3 to 12 months of age. METHODS A retrospective review of 68 infants who underwent balloon angioplasty for native CoA. 95% CI are in parentheses. RESULTS Procedural age was (mean±SD) 6±3.4 months and weight was 7±1.8 kg. Balloon angioplasty produced a large decrease in both the noninvasive arm-to-leg blood pressure gradient (41.2±18.7 to 5.6±9.6 mm Hg) and the invasive peak systolic pressure gradient (34±12 to 11±9 mm Hg). Balloon angioplasty increased the CoA diameter from 2.7±1 mm to 4.6±1.2 mm. One patient was lost to follow-up. A catheter reintervention was required in 11.8% and surgery in 10.3%. The hazard of reintervention was highest early. Median freedom from reintervention was 89% (95% CI, 80%-96%) at 1 year, 83% (95% CI, 73%-92%) at 5 years, and 81% (95% CI, 69%-90%) at 10 years. Femoral artery thrombosis was documented in 6 (9%) infants without any long-term consequence. One patient developed a small aortic aneurysm late and has not required treatment. A robust estimate of the frequency of aortic aneurysms remains to be determined as the majority of subjects have not had cross-sectional imaging. CONCLUSIONS Balloon angioplasty of native CoA is effective and safe in infants aged 3 to 12 months with outcomes comparable to those in older children and adults. Catheter reinterventions can avoid the need for surgery in most patients.

Abstract
OBJECTIVES To assess the efficacy and safety of balloon angioplasty (BAP) procedure for treatment of coarctation of the aorta (CoA) in children. Methods: A retrospective study included 27 consecutive children, underwent BAP for either native-CoA (Na-CoA) or recoarctation (Re-CoA). Medical records, echocardiographic findings, angiographic and hemodynamic data were collected from the hospital database. Follow‑up was scheduled at 1, 3, 6, 12 months after the procedure. The study took place over a period of 4.5 years, from April 2014 to January 2019, in Madinah Cardiac Center, Madinah, Northwest region, Saudi Arabia. RESULTS The mean age of patients was 11.86±8.96 months. Seven children had Na-CoA and 20 children had Re-CoA. The success rate of the procedure was achieved in 23 children (85%), as BAP reduced the mean systolic pressure gradient across the CoA (Na-CoA: from 45.28± 18.3 to 9.8± 6.57 mm Hg, p=0.0009), and in Re-CoA groups (from 42.48±16.7 to 10.9±8.5 mm Hg, p less than 0.0001). In mid-term follow-up, the need for re-intervention occurred in 8 children of the cohort (3 children [42.8%] from the Na-CoA group, and 5 children [25%] from the Re-CoA group). Conclusions: Balloon angioplasty is considered a safe procedure for the management of CoA, but its efficacy remains questionable especially for young infants with Na-CoA type. However, it is a reliable option for managing Re-CoA children, with a lower rate of future re-intervention.

Abstract
OBJECTIVES AND BACKGROUND Coarctation of the aorta represents 5-8% of all congenital heart disease. Although balloon expandable stents provide an established treatment option for native or recurrent coarctation, outcomes from transverse arch (TAO) stenting, including resolution of hypertension have not been well studied. This study aims to evaluate immediate and midterm results of TAO stenting in a multi-center retrospective cohort. METHODS TAO stenting was defined as stent placement traversing any head and neck vessel, with the primary intention of treating narrowing in the transverse aorta. Procedural details, complications and medications were assessed immediately post procedure, at 6 month follow-up and at most recent follow-up. RESULTS Fifty-seven subjects, 12 (21%) native, and 45 (79%) surgically repaired aortic arches, from seven centers were included. Median age was 14 years (4 days-42 years), median weight 54 kg (1.1-141 kg). After intervention, the median directly measured arch gradient decreased from 20 mmHg (0-57 mmHg) to 0 mmHg (0-23 mmHg) (p < .001). The narrowest arch diameter increased from 9 mm (1.4-16 mm) to 14 mm (2.9-25 mm) (p < .001), with a median increase of 4.9 mm (1.1-10.1 mm). One or more arch branches were covered by the stent in 55 patients (96%). There were no serious adverse events. Two patients warranted stent repositioning following migration during deployment. There were no late complications. There were 8 reinterventions, 7 planned, and 1 unplanned (6 catheterizations, 2 surgeries). Antihypertensive management was continued in 19 (40%) at a median follow-up of 3.2 years (0.4-7.3 years). CONCLUSIONS TAO stenting can be useful in selected patients for resolution of stenosis with minimal complications. This subset of patients are likely to continue on antihypertensive medications despite resolution of stenosis.

Abstract
Aortic coarctation is a discrete narrowing of the thoracic aorta. In addition to anatomic obstruction, it can be considered an aortopathy with abnormal vascular properties characterized by stiffness and impaired relaxation. There are surgical and transcatheter techniques to address the obstruction but, despite relief, patients with aortic coarctation are at risk for hypertension, aortic complications, and abnormalities with left ventricular performance. This review covers the etiology, pathophysiology, diagnosis, and management of adults with aortic coarctation, with emphasis on multimodality imaging characteristics and lifelong surveillance to identify long-term complications.

Cardiac Catheterisation Interventions in Neonates and Infants Less Than Three Months. J Saudi Heart Assoc 2020; 32:149-156. [PMID: 33154909 PMCID: PMC7640550 DOI: 10.37616/2212-5043.1051] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 05/14/2019] [Accepted: 02/27/2020] [Indexed: 11/20/2022] Open
Abstract
Introduction Pediatric cardiac catheterization interventions become an established way of care for selected patients with congenital heart diseases. Cardiac catheterization for neonates and small infants can be challenging. The indications for diagnostic cardiac catheterization have decreased with the advent of advanced non-invasive imaging modalities. Patients and method Between June 2012 and July 2017 patients less than three months who had cardiac catheterization in two centers were reviewed. Results During the study period, 174 patients underwent interventional cardiac catheterization,83.3% of them had CHD with two-ventricle circulation and 29 patients (16.7%) had single ventricle pathophysiology. Procedures include diagnostic cath, BAS, balloon pulmonary and aortic valvuloplasty, coarctation angioplasty, and stenting procedures. The vascular access depends upon the type of procedure. All except one had general anesthesia. ICU admission was required on 106 patients (62%). Patients were divided according to the type of cardiac lesion (single versus biventricular pathology) as well as according to the type of intervention (stenting and non-stenting procedures). Comparing these groups revealed that: stent procedures and procedures for patients with single ventricle pathologies were performed at an earlier age, with more contrast, fluoro and procedure time than for non-stent procedures and procedures for patients with biventricular pathologies. Complications include transient arrhythmias in most patients, perforation of the RVOT in one and lower limb hypoperfusion in 12 patients. ICU complications include low cardiac output symptoms (LCOS) in 10 (7%), and sepsis in 8. No intra-procedure mortality. The overall survival was 94%. Ten patients died, with one early and 9 late mortality. 60% of the dead patients had PDA stenting. Reintervention varies according to the patient's diagnosis. Conclusion Cardiac catheterization intervention an important modality in the management of neonates and infants with critical CHD. Well planned procedures and team expertise are essential. Stenting procedures and procedures for patients with single ventricles carries higher morbidity and mortality.

Abstract
Objective Percutaneous cardiac catheterization has been used as a diagnostic tool and as a therapeutic option in neonates with congenital heart disease (CHD). This study aimed to evaluate the procedural and short-term follow-up data of newborns who underwent cardiac catheterization procedures. Methods This retrospective study reviewed demographic, diagnostic and clinical data from the medical records of newborns who underwent percutaneous transcatheter interventions to treat CHD. Results Forty-six newborns were included in the study. The median gestational week and weight were 35.0 weeks and 2723 g, respectively. The median time to the procedure was 7.6 days. Aortic and pulmonary balloon valvuloplasty, ductal stenting, atrial balloon/blade septostomy and coronary fistula embolization procedures were used. The overall success rate was 73.9% (34 of 46 patients) with a complication rate of 28.3% (13 of 46 patients). Eleven patients (23.9%) underwent reinterventions after initial catheterization. Five patients (10.9%) died in the first 48 h after their procedures. Conclusions Interventional cardiological procedures applied during the neonatal period provide alternative life-saving methods to surgery, especially in developing countries where surgical outcomes are poor and newborn mortality rates are high.

Abstract
Coarctation of the aorta is a common congenital heart defect and can present at any age. Infants may carry a fetal diagnosis, or are generally diagnosed after auscultation of a murmur, although rarely present in shock. Those that escape early childhood detection typically present in adolescence and adulthood, generally with upper-extremity hypertension. Percutaneous therapies have evolved to include balloon angioplasty and stent placement, and generally are the preferred first-line therapy for most adolescent/adult patients. Percutaneous interventions are now viable options in younger and smaller patients. The advent of bioresorbable stents may provide further expansion of treatment options to very small patients.

Abstract
Objective In the present study, we aimed to retrospectively investigate the early and late results of different surgical treatment techniques applied in different age groups with coarctation of the aorta (CoA). Materials and Methods Between January 2007 and February 2017, 26 patients (12 males, 14 females; mean age: 12.2±12.4 years; range: 29 days-34 years) who underwent surgery with the diagnosis of CoA were evaluated. Overall, 11 of these patients (42.3%) were in the infantile period, whereas 15 patients (57.7%) aged between 6 and 34 years. Resection and end-to-end anastomosis were performed in 13 patients (50%). Bypass grafting was performed in six patients (23.1%), and patch plasty was performed in seven patients (26.9%). Results A patient (3.8%) who was operated on during the infantile period died early, whereas another patient (3.8%) died 2 years after the surgery. Recoarctation was detected in two patients. A patient underwent balloon dilatation, whereas another patient underwent balloon dilatation and stenting. In patients who underwent re-section and end-to-end anastomosis based on postoperative echocardiography results during follow-up, a lower statistically significant gradient was observed compared with the preoperative period. Despite the decrease in the left ventricular systolic diameter (LVSD) and the increase in the ejection fraction (EF) the decrease in LVSD and increase in EF were not statistically significant. In patients who underwent patch plasty or graft interposition, the low values of the gradient and left ventricular diastolic diameter in the postoperative follow-up were statistically significant. However, the decrease in LVSD and increase in EF were not statistically significant. Conclusions Our clinical experience suggests that repairing with resection and end-to-end anastomosis is a more appropriate treatment option during the infancy, whereas patch plasty or bypass grafting may be preferred in advanced ages.

Abstract
BACKGROUND There is no systematic assessment of available evidence on effectiveness and comparative effectiveness of balloon dilatation and stenting for aortic coarctation. METHODS AND RESULTS We systematically searched 4 online databases to identify and select relevant studies of balloon dilatation and stenting for aortic coarctation based on a priori criteria (PROSPERO 2014:CRD42014014418). We quantitatively synthesized results for each intervention from single-arm studies and obtained pooled estimates for relative effectiveness from pairwise and network meta-analysis of comparative studies. Our primary analysis included 15 stenting (423 participants) and 12 balloon dilatation studies (361 participants), including patients ≥10 years of age. Post-treatment blood pressure gradient reduction to ≤20 and ≤10 mm Hg was achieved in 89.5% (95% confidence interval, 83.7-95.3) and 66.5% (44.1-88.9%) of patients undergoing balloon dilatation, and in 99.5% (97.5-100.0%) and 93.8% (88.5-99.1%) of patients undergoing stenting, respectively. Odds of achieving ≤20 mm Hg were lower with balloon dilatation as compared with stenting (odds ratio, 0.105 [0.010-0.886]). Thirty-day survival rates were comparable. Numerically more patients undergoing balloon dilatation experienced severe complications during admission (6.4% [2.6-10.2%]) compared with stenting (2.6% [0.5-4.7%]). This was supported by meta-analysis of head-to-head studies (odds ratio, 9.617 [2.654-34.845]) and network meta-analysis (odds ratio, 16.23, 95% credible interval: 4.27-62.77) in a secondary analysis in patients ≥1 month of age, including 57 stenting (3397 participants) and 62 balloon dilatation studies (4331 participants). CONCLUSIONS Despite the limitations of the evidence base consisting predominantly of single-arm studies, our review indicates that stenting achieves superior immediate relief of a relevant pressure gradient compared with balloon dilatation.

Abstract
In pediatric cardiovascular surgery, there is a significant need for vascular prostheses that have the potential to grow with the patient following implantation. Current clinical options consist of nonexpanding conduits, requiring repeat surgeries as the patient outgrows the device. To address this issue, PECA Labs has developed a novel ePTFE vascular conduit with the capability of being radially expanded via balloon catheterization. In the described study, a systematic characterization and comparison of two proprietary ePTFE expandable conduits was conducted. Conduit sizes of 8 and 16 mm inner diameters for both conduits were evaluated before and after expansion with a 26 mm balloon. Comprehensive mechanical testing was completed, including quantification of circumferential, and longitudinal tensile strength, suture retention strength, burst strength, water entry pressure, dynamic compliance, and kink radius. Scanning electron microscopy was used to investigate the microstructural properties. Automated extraction of the fiber architectural features for each scanning electron micrograph was achieved with an algorithm for each conduit before and after expansion. Results showed that both conduits were able to expand significantly, to as much as 2.5× their original inner diameter. All mechanical properties were within clinically acceptable values following expansion. Analysis of the microstructure properties of the conduits revealed that the circumferential main angle of orientation, orientation index, and spatial periodicity did not significantly change following expansion, whereas the node area fraction decreased post expansion. Successful proof-of-concept of this novel product represents a critical step toward clinical translation and provides hope for newborns and growing children with congenital heart disease. © 2017 Wiley Periodicals, Inc.

Abstract
INTRODUCTION Balloon angioplasty (BAP) and aortic or pulmonary balloon valvuloplasty (BAV, BPV) are well-established treatment options in congenital heart defects. Recently, significant technological progress has been made and new catheters have been implemented in clinical practice. AIM To analyze the results of BAP, BAV and BPV with the new balloon catheter Valver and its second generation Valver II, which the company Balton (Poland) launched and developed. These catheters have not been clinically evaluated yet. MATERIAL AND METHODS We performed 64 interventions with Valver I and Valver II. With Valver I the following procedures were performed: 17 BPV (including 9 in tetralogy of Fallot - TOF), 10 BAV and 27 BAP in coarctations of the aorta (CoA) - including 9 native and 18 after surgery. With Valver II ten interventions were done - 3 BPV, 2 pulmonary supravalvular BAP (after switch operations), 2 BAP of recoarctations and 3 other BAP. Age of the patients ranged from a few days to 40 years. RESULTS All procedures were completed successfully, without rupture of any balloon catheters. The pressure gradient drop was statistically significant in all groups: BPV in isolated pulmonary valvular stenosis 28.1 mm Hg (mean), BPV in TOF 18.7 mm Hg, BAV 32.8 mm Hg, BAP in native CoA 15.4 mm Hg and in recoarctations 18.6 mm Hg. In 3 cases during rapid deflation of Valver I, wrinkles of the balloons made it impossible to insert the whole balloon into the vascular sheath (all were removed surgically from the groin). No such complication occured with Valver II. CONCLUSIONS Valver balloon catheters are an effective treatment modality in different valvular and vascular stenoses.

Abstract
BACKGROUND The hybrid technique combining balloon angioplasty for discrete coarctation (CoA) and surgical repair of a ventricular septal defect (VSD) is a novel treatment for patients with aortic CoA and VSD, but the efficacy of this approach is unknown. METHODS We performed a retrospective analysis of 92 patients with short segment CoA and VSD who underwent complete repair between January 2004 and July 2014 in our center. Patients were divided into two groups according to the surgical approach employed: hybrid procedure (group A, n=39) and traditional midline surgical repair (group B, n=53). Baseline, perioperative, and outcome data were compared between the two groups. RESULTS Three early deaths occurred in group B, whereas none occurred in group A. Compared to those in group B, patients in group A experienced a shorter aortic clamp duration (28.1±6.7 vs. 43.2±9.2 minutes, P<0.001), shorter cardiopulmonary bypass (CPB) duration (52.9±10.7 vs. 86.2±23.8 minutes, P<0.001), shorter ventilator time (47.0 vs. 73.7 hours, P=0.002), and shorter intensive care unit stay (6.2 vs. 9.1 days, P=0.019). The risks for aortic re-CoA and re-intervention did not differ significantly between the groups within five years (P=0.40 and 0.65, respectively). CONCLUSIONS The hybrid technique was associated with better periprocedural outcomes for patients with short-segment CoA and VSD. The incidences of aortic re-CoA and re-intervention were comparable between the hybrid technique and surgical groups over a mid-term follow-up.

Abstract
Coarctation of the aorta is a relatively common form of congenital heart disease, with an estimated incidence of approximately 3 cases per 10000 births. Coarctation is a heterogeneous lesion which may present across all age ranges, with varying clinical symptoms, in isolation, or in association with other cardiac defects. The first surgical repair of aortic coarctation was described in 1944, and since that time, several other surgical techniques have been developed and modified. Additionally, transcatheter balloon angioplasty and endovascular stent placement offer less invasive approaches for the treatment of coarctation of the aorta for some patients. While overall morbidity and mortality rates are low for patients undergoing intervention for coarctation, both surgical and transcatheter interventions are not free from adverse outcomes. Therefore, patients must be followed closely over their lifetime for complications such as recoarctation, aortic aneurysm, persistent hypertension, and changes in any associated cardiac defects. Considerable effort has been expended investigating the utility and outcomes of various treatment approaches for aortic coarctation, which are heavily influenced by a patient’s anatomy, size, age, and clinical course. Here we review indications for intervention, describe and compare surgical and transcatheter techniques for management of coarctation, and explore the associated outcomes in both children and adults.

Abstract
Coarctation of the aorta (CoA), while usually identified and treated in the neonatal/infant period, is increasingly seen in adults, either primarily or (more often) following repair. Imaging plays a crucial role in the diagnosis, therapeutic planning, and follow-up of patients with CoA. Clinical management of CoA in adults optimally involves a multidisciplinary team; accordingly, imagers should be familiar with the underlying pathology, associations, and management of CoA in addition to imaging protocoling and interpretation. We will review the relevant clinical and imaging features of CoA, with an emphasis on patients beyond childhood.

Abstract
Coarctation of the aorta (CoA) accounts for 5% to 8% of all congenital heart defects. With all forms of interventions for native CoA, repeat intervention may be required due to restenosis and/or aneurysm formation. Restenosis rates vary from 5% to 24% and are higher in infants and children and in those with arch hypoplasia. Although repeat surgery can be done for recurrent CoA, guidelines from a number of professional societies have recommended balloon angioplasty with or without stenting as the preferred intervention for patients with isolated recoarctation. For infants and young children with recurrent coarctation, balloon angioplasty has been shown to be safe and effective with low incidence of complications. However, the rates of restenosis and reinterventions are high with balloon angioplasty alone. Endovascular stent placement is indicated, either electively in adults or as a bailout procedure in those who develop a complication such as dissection or intimal tear after balloon angioplasty. Conventionally bare metal stents are used; these can be dilated later if required. Covered stents, introduced more recently, are best reserved for those who have aneurysm at the site of previous repair or who develop a complication such as aortic wall perforation or tear. Stents produce complete abolition of gradients across the coarct segment in a majority of cases with good opening of the lumen on angiography. The long-term results are better than that of balloon angioplasty alone, with very low rates of restenosis. However, endovascular stenting is a technically demanding procedure and can be associated with serious complications rarely.

Abstract
Surgery for congenital heart disease has advanced significantly in the past 50 years, such that repair of "simple" lesions, such as atrial septal defect, ventricular septal defect, and coarctation of the aorta carries minimal risk, with mortality risk much less than 1%. It was once thought successful repair of these lesions was definitively corrective. There is mounting evidence, however, that there are long-term complications after these repairs, prompting the need for continued follow-up. This review describes the current understanding of diagnosis, treatment, and long-term outcomes for these patients, with the goal of advocating for lifelong surveillance. As the perioperative care of these repairs has evolved significantly over time, so must the way in which we study these patients in the long-term.

Abstract
This report describes the management of a 28-year-old female patient who presented with septicemia and mediastinal mass-effect secondary to a proximal mycotic aneurysm of the descending aorta. The patient had an infected bicuspid aortic valve, aortic coarctation, and a left vertebral artery arising directly from the aortic arch. Evidence of disseminated embolization affecting her posterior cerebral circulation, the left axillary, and the superior mesenteric arteries was noted. The patient had a considerably small aorta. An urgent thoracic endovascular aortic repair was performed successfully with a chimney stent to the left vertebral artery. The report discusses the planning and technique used in managing this complex case.
