Correlation between pressure gradient from echocardiography and peak-to-peak pressure gradient from cardiac catheterization or surgery in patients with coarctation of aorta. THE INTERNATIONAL JOURNAL OF CARDIOVASCULAR IMAGING 2024; 40:1193-1200.

Abstract
The gold standard for assessing pressure gradients (PG) across coarctation involves measurements obtained through cardiac catheterization or surgical intervention. There has been ongoing discussion regarding the accuracy of non-invasive methods for estimating these gradients. This study sought to establish the correlation and agreement between the systolic blood pressure (SBP) gradient between the upper and lower extremities, as well as, the mean and maximum PG derived from echocardiography, in comparison to the peak-to-peak pressure gradient obtained from either cardiac catheterization or surgery. We conducted a retrospective study on patients < 18 years diagnosed with coarctation at Chiang Mai University Hospital from 2011 to 2022. The study involved the measurement of the SBP gradient between the upper and lower extremities, mean and maximum PG using echocardiography, peak-to-peak pressure gradient obtained from cardiac catheterization, and pressure gradient recorded during surgical procedures. The Spearman's correlation and Bland-Altman analysis were employed to assess correlation and agreement. Fifty-four patients with aortic coarctation were enrolled. The mean PG measured by echocardiography showed a significantly moderate correlation (r = 0.78, p < 0.001) and the highest level of agreement according to Bland Altman plots, in comparison to the peak-to-peak pressure gradient measured during both cardiac catheterization and surgical procedure. The max PG demonstrated a notable overestimation compared to the gold standard (mean difference + 13.14 with a slope of biases + 0.64, p < 0.001). The mean PG obtained through echocardiography has more potential to be applied in practical application in predicting pressure gradient in patients with coarctation.

Abstract
OBJECTIVE Coarctation of the Aorta (CoA) is a relatively common cardiovascular disorder. The present study aimed to evaluate the effect of COA anatomy and high versus low-pressure balloons on the outcome of balloon angioplasty among neonates and infants. METHODS In this retrospective study, the neonates and infants undergoing balloon angioplasty at Namazi hospital were enrolled. After balloon angioplasty, immediate data results were promptly recorded.Moreover, midterm echocardiographic information was collected via electronic cardiac records of pediatric wards and clinical and echocardiographic data at least 12 months after balloon angioplasty. Finally, data were analyzed using SPSS-20. RESULTS In this study, 42 infants were included. The median age at the time of balloon angioplasty was 1.55 (range 0.1-12) months and 66.7% of the patients were male. The mean pressure gradient of coarctation was 38.49 ± 24.97 mmHg, which decreased to 7.61 ± 8.00 mmHg (P < 0.001). A high-pressure balloon was used in 27, and a low-pressure balloon was used in 15 patients. COA's pressure gradient changed 30.89 ± 18.06 in the high-pressure group and 24.53 ± 20.79 in the low-pressure balloon group (P = 0.282). In the high-pressure balloon group, 14.81% and in the low-pressure group, 33.33% had recoarctation and need second balloon angioplasty (p < 0.021). The infant with discrete coarctation had a higher decrease in gradient and lower recoarctation. CONCLUSION Recoarctation rate was lower in the high-pressure balloon. The infant with discrete COA had a better response to the balloon with more decrease in gradient and lower recoarctation rate. Therefore, the stenotic segment anatomy needs to be considered in the selection of treatment methods.

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.

Application of Modified Sliding Anastomosis in the Repair of Aortic Coarctation. BIOMED RESEARCH INTERNATIONAL 2020; 2020:3805385. [PMID: 32509857 PMCID: PMC7245663 DOI: 10.1155/2020/3805385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 04/19/2020] [Accepted: 05/02/2020] [Indexed: 11/17/2022]
Abstract
Objectives To evaluate the early and midterm results of a modified sliding anastomosis technique in patients with aortic coarctation. Materials and Methods In this study, we reported a new repair method and compared the early and midterm outcome(s) with a conventional surgical approach for the management of patients with aortic coarctation. Forty-eight aortic coarctation patients with a narrowed segment length longer than 2 cm were operated at our department's pediatric surgical division. Excision of the coarctation and end-to-end anastomosis was carried out in twenty-five patients (control group). In contrast, a modified sliding technique was used for twenty-three cases in the observation group. Other accompanying cardiac anomalies simultaneously repaired included ventricular septal defect and patent ductus arteriosus. All patients received 1.5-10 years of postoperative echocardiographic follow-up. Results This is a retrospective study carried out between January 2005 and June 2018. The study population consisted of forty-eight patients, which included twenty-six male and twenty-two female patients, with an average age of 5.2 ± 1.9 months (range, 28 days to 1 year). There was no mortality. The operative time, the number of intercostal artery disconnection, the drainage volume, and arm-leg systolic pressure gradient postoperation were less in the observation group as compared to the control group (p < 0.05). Also, cases with an anastomotic pressure gradient exceeding 10 mmHg during follow-up were less in the observation group as compared to the control group (p < 0.05). The postoperative complications encountered were chylothorax (control group 2 cases vs. observation group 0) and pulmonary atelectasis (control group 4 cases vs. observation group 1). They all, however, recovered after conservative treatment. Three patients in the control group underwent balloon angioplasty (reintervention) postoperative 2-4 years due to an increase in the anastomotic pressure gradient (>20 mmHg). After reintervention, the anastomotic pressure gradient reduced to 14 mmHg, 15 mmHg, and 17 mmHg, respectively. Conclusions For long segment aortic coarctation patients (longer than 2 cm), the use of the modified sliding anastomotic technique effectively helps to retain more autologous tissues, enlarge the diameter of the anastomosis, and decrease anastomotic tension and vascular injury. Therefore, this technique provides a new idea for the surgical treatment of aortic coarctations.

Abstract
A 28-year-old pregnant woman presents with arterial hypertension of the upper limbs. The examination suggests an aortic coarctation. After a normal delivery, a contrast-enhanced computed tomography revealed a subocclusive aortic coarctation of the descending thoracic aorta and a 33-mm aneurysm developed from the left cervical-thoracic artery. The coarctation of the aorta was treated by a stent graft, and the aneurysm was treated by an injection of thrombin and glue.

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
Balloon angioplasty (BAP) used to manage native coarctation of the aorta (CoAo) in infants remains controversial. This study aimed to compare short- and midterm results of BAP between native CoAo (NaCo) and postsurgical recoarctations (ReCo) in infants younger than 1 year. This retrospective study compared the clinical, echocardiographic, hemodynamic, and angiographic data for infants who underwent BAP between July 2003 and September 2012. The 12 NaCo and 13 ReCo patients in this study underwent BAP at 4.61 ± 3.69 and 4.88 ± 3.07 months (p = 0.84) and weighed 5.49 ± 2.57 and 6.10 ± 2.11 kg (p = 0.52), respectively. Their respective heights were 60.58 ± 10.58 and 61.15 ± 6.74 cm (p = 0.87). All the ReCo patients had their initial surgery before the age of 3 months. The minimal CoAo diameter was 2.81 ± 0.96 mm in the NaCo group and 2.86 ± 1.0 mm in the ReCo group (p = 0.90). The relative gradient reduction was 62.79 ± 32.43 % in the NaCo group and 73.37 ± 20.78 % in the ReCo group (p = 0.33). The in situ complication rate (pseudoaneurysm) was 8.33 % in the NaCo group and 7.69 % in the ReCo group (p = 0.74). During the early follow-up evaluation, five NaCo patients (41.66 %) presented with recoarctation requiring BAP reintervention within 1.75 ± 1.41 months (all had their initial BAP before 3 months of age) compared with 1 ReCo patient (7.69 %) (p = 0.165). The mean follow-up period was 3.09 ± 2.69 years for the NaCo patients and 3.6 ± 3.18 years for the ReCo patients (p = 0.69), during which the blood pressure gradient was 12.33 ± 9.67 for the NaCo patients and 7.80 ± 8.78 for the ReCo patients (p = 0.17), with corresponding Doppler peak instantaneous gradients of 21.29 ± 11.19 and 16.20 ± 10.23 (p = 0.24). The resultant diameter ratio between the minimal isthmus diameter and the aortic diameter at the diaphragmatic level was 0.81 ± 0.15 in the NaCo group and 0.85 ± 0.12 in the ReCo group (p = 0.53). The immediate and midterm results of BAP for the NaCo and ReCo infants were comparable. Accordingly, BAP seems to be an acceptable alternative to surgery for infants older than 3 months.

Abstract
OBJECTIVES Describe outcomes from stenting transverse aortic arch hypoplasia. BACKGROUND Hypoplasia of the transverse arch may result in residual systemic hypertension and may be amenable to stenting. METHODS Outcomes for transverse aortic arch hypoplasia stenting were collated from four centers between 2000 and 2010. Primary endpoints were reduction in peak systolic catheter gradient, dimensions of the stented segment, and systolic right arm blood pressure. Changes in antihypertensive medication and early and late complications were recorded. Data were collated for 21 patients (16 male, 5 female), median age of 16.5 years (range, 0.25-25.9 years) and median weight of 55 kg (range, 4.5-103 kg). 19/21 patients were hypertensive at baseline, excluding the two neonates after repair of interrupted aortic arch. RESULTS Median transverse arch diameter increased from 7 to 14 mm after stenting (P < 0.001). Median ratio of the transverse arch to descending aorta at the diaphragm level improved from 0.43 to 0.9 (P < 0.001). Mean gradient across the hypoplastic transverse arch was 38 mm Hg (range, 14-76) at baseline and 5 mm Hg (range, 0-13) after stenting (P < 0.001). There were no deaths and 6 early complications occurred in 5 patients. Follow-up (median 24 months) data were available for 19 patients. 17/19 hypertensive patients had follow-up data. Two neonates developed intimal hyperplasia within the stent with a stent fracture in one. Median systolic blood pressure was 153 mm Hg (range, 117-180) prestent and 130 mm Hg (range, 105-150) poststent (P = 0.0002). In 13/17 patients, the antihypertensive medication could be reduced. CONCLUSIONS Stenting of transverse aortic arch hypoplasia, although technically challenging, produced good angiographic and haemodynamic results with an early improvement in blood pressure control. These results appear to be sustained in the medium term.

Abstract
Untreated thoracic aortic coarctation leads to early death predominantly because of hypertension and its cardiovascular sequelae. Surgical treatment has been available for > 50 years and has improved hypertension and survival. More recently, endovascular techniques have offered a minimally invasive alternative to traditional open repair. Early and intermediate results suggest angioplasty and stenting have an important role in the management of aortic coarctation, particularly in adults and older children.

Abstract
OBJECTIVE The aim of the study was to analyze immediate results, rate of complications and re-interventions during medium-term outcome in pediatric patients with native or recurrent aortic coarctation. We focused on an age-related therapeutic approach comparing surgical and trans-catheter treatment. METHODS This is a retrospective, single-centre, clinical observational trial including 91 consecutive patients (age: 1 day-18 years) treated for native coarctation in 67 and recurrent aortic coarctation in 24 patients. Surgical treatment was performed in 56, trans-catheter treatment with balloon dilatation in 17, and by stent implantation in 18 patients. According to the age groups, we treated 48 children in group A (<6 months of age), 16 in group B (6 months-6 years), and 27 in group C (>6 years). A total of 41 patients in group A were operated (85%), patients in group B received either surgical or trans-catheter treatment (50% vs 50%), and 16 patients in group C were treated by stent implantation (62%). RESULTS Immediate results were excellent with a significant release of pressure gradient in all three age groups (64.7% in group A, 69.1% in group B, and 63.3% in group C). Complication rate and re-intervention rate (surgical and interventional) both were [corrected] comparable between the three age groups (complications: group A 8.3%, group B 6.3%, and group C 3.7%, [corrected] re-interventions: group A 16.6%, group B 18.8%, and group C 14.8%). [corrected] Midterm outcome after a median follow-up period of 17.5 months was satisfactory with a re-intervention-free survival after 17.5 months of 83.4%, 81.2%, and 81.5% in group A, group B, and group C, respectively. CONCLUSIONS The current strategy of an age-related therapy for native and recurrent aortic coarctation in our institution is surgery in infants <6 months (group A), either surgery or balloon dilatation in younger patients <6 years (group B), while in older children >6 years of age (group C) the trans-catheter treatment with stent implantation is an excellent alternative to surgery. Balloon dilatations showed limited results with an overall re-intervention rate of 53% and, therefore, should mainly be performed as a rescue procedure or in recurrent aortic coarctation in neonates.

Late cardiovascular complications after surgical or balloon angioplasty of coarctation of aorta in an Asian cohort. Am J Cardiol 2009; 104:1139-44.

Abstract
Late cardiovascular complications after intervention for coarctation of the aorta (CoA) might be common. Such data, especially in Asian populations, are still limited. A total of 169 patients with CoA who survived balloon (n = 41) or surgical (n = 128) intervention from 1986 to 2004 were enrolled. The total follow-up was 1,776 patient-years, and the patient age at last follow-up was 14.7 +/- 8.5 years. Reintervention for recoarctation, systemic hypertension, and left ventricular outflow tract obstruction (LVOTO) was subsequently noted in 57 (34%), 36 (21.3%), and 24 (14.2%) patients, respectively, without significant differences between the balloon and surgical groups. The 20-year freedom from reintervention, systemic hypertension, and LVOTO rate was 52%, 78.6%, and 80.8% in the balloon group and 59%, 51%, and 81.9% in the surgical group, respectively. The age at CoA intervention and the aortic geometry after CoA intervention of gothic type were common risk factors for reintervention for recoarctation and late systemic hypertension. In contrast, the presence of bicuspid aortic valves and gothic arch geometry after CoA intervention increased the risk of LVOTO. Plasma renin/aldosterone activities were not elevated in those with or without systemic hypertension. In conclusion, the profile of reintervention for recoarctation and late systemic hypertension after CoA interventions in our Asian cohort with CoA was similar to that observed in white patients. Asian patients might have a lower risk of LVOTO.

Abstract
OBJECTIVES To evaluate cardiac size and function in patients with coarctation of the aorta (CoA) before and after treatment. DESIGN Ventricular size and function were examined by 2- and 3-dimensional echocardiography, and concentrations of natriuretic peptides measured in 15 paediatric patients before repair, and one, 6, and 12 months thereafter. Controls comprised 15 children. RESULTS Before repair, mitral inflow velocities and left ventricular (LV) size and wall thickness were higher in patients. Thicknesses of interventricular septum and LV posterior wall decreased after repair but increased to initial level one year thereafter. The LV end-diastolic diameter remained larger than in controls despite successful repair. The size of right ventricle increased and levels of natriuretic peptides decreased during follow-up. Levels of natriuretic peptides correlated with the smallest diameter of CoA segment and diastolic indices of LV function. CONCLUSION LV hypertrophy persists and LV size remains larger than in controls after successful repair even in normotensive patients with normal growth of CoA segment. This may be due to remodelling of ventricles and the aorta caused by CoA.

Abstract
BACKGROUND AND AIMS Although the immediate and intermediate-term results of balloon angioplasty (BA) for patients with aortic coarctation (AC) have been encouraging, there is paucity of data on long-term follow-up results. This study evaluated the long-term (up to 22 years) follow-up results of BA in adolescent and adult patients with discrete (shelf-like) coarctation of the aorta. METHODS Follow-up data of 58 patients (mean age 24+/-9 years) undergoing BA for discrete AC at median interval of 13.4 years including cardiac catheterization, magnetic resonance imaging, and Doppler echocardiography form the basis of this study. RESULTS No early deaths occurred. Balloon angioplasty produced immediate reduction in peak AC gradient from 60+/-22 mm Hg to 8.5+/-8 mm Hg (P<.0001). Follow-up catheterization 12 months later revealed a residual gradient of 5+/-6.4 mm Hg (P=.01). Five patients (8%) with suboptimal initial outcome (peak gradient>20 mm Hg) developed restenosis, and 4 of these had successful repeat angioplasty. Aneurysm developed at the site of dilatation in 4 patients (7%). Magnetic resonance imaging follow-up results revealed no new aneurysm. In one patient, the aneurysm increased in size, but no recoarctation or appreciable changes in the Doppler gradient across the AC site was noted. The blood pressure had normalized without medical treatment in 29 (50%) of the 58 patients. CONCLUSION Long-term results of BA for discrete AC are excellent and should be considered as first option for treatment of this disease.

Abstract
Balloon angioplasty for native coarctation of the aorta in infants and children is gaining acceptance as an alternative to surgery in discrete membranous obstruction. The aim of this study was to assess the immediate and intermediate-term effectiveness and safety of balloon angioplasty in infants and children with discrete membranous obstruction and mild complex arch anomalies. We performed a retrospective study evaluating the immediate and intermediate-term results of balloon angioplasty in 46 consecutive patients with native coarctation of the aorta done between March 1998 and June 2003. Isolated discrete fibromembranous obstruction occurred in 32 patients, and 14 patients had mild complex arch anomalies. Follow-up was obtained in 40 patients. There was no early mortality. The procedure was initially successful in 43 patients (93%). There were three immediate failures. Of the 40 patients who were followed, 32 (80%) had maintained a cuff pressure gradient of 20 mmHg across the dilated area. Four patients developed restenosis, which was successfully treated by repeated balloon angioplasty. The other four patients continued to have mild gradient (20-22 mmHg) with systolic hypertension and without angiographic evidence of restenosis but with isthmus hypoplasia; they received atenolol and captopril. Serial echocardiographic measurement of left ventricular dimension and function revealed significant improvement after balloon angioplasty of aortic coarctation in patients with the echocardiographic picture of hypertensive cardiomyopathy. Balloon angioplasty may be considered as a tool in the armamentarium of management of aortic coarctation in different anatomic variants, taking into consideration the clinical presentation and patient age.

Abstract
Obstructive lesions in the aortic arch are comprised of discrete coarctation, tubular hypoplasia and interruption. This review discusses the anatomy of the lesions relevant to interventional treatment. Catheter intervention, using not only balloon angioplasty but also stent implantation for coarctation, has been developed over the past couple of decades as an alternative treatment to surgery. Several studies have reported long-term outcome and the benefits of surgery and catheter intervention for treating obstructive lesions in the aortic arch but more studies are needed for comparable evaluations. The development of imaging and further improvement of surgical and catheter intervention, such as hybrid intervention or new devices, will help in removing the obstruction safely.

Abstract
BACKGROUND There is a high incidence of restenosis and aneurysm formation after balloon angioplasty for discrete native coarctation in neonates and young infants, and so the techniques remains controversial in this group of patients because its clinical validity, particularly in comparison with surgery, has not been well established. METHODS AND RESULTS From January 1999 to October 2005, group A (17 patients [8 males, 9 females] <3 months old ranging from 0.2 to 2.9 months, with a body weight of 2.5-5.5 kg) and group B (11 patients [5 males, 6 females] >3 months old ranging from 5.5 months to 6.4 years, with a body weight of 7.8-21 kg) with discrete native coarctation who underwent balloon angioplasty and were included in this study. There were 13 (76%) successes in group A, and 10 (90%) successes in group B for the initial balloon angioplasty. There was no significant difference in success rate between groups A and B (p>0.05). There were 9 (69%) cases of restenosis patients in group A, and 2 (20%) in group B, a significant difference between the 2 groups (p<0.05). In group A, 1 patient showed aneurysm formation after angioplasty, 1 (5.8%) showed femoral artery obstruction and 2 (11%) showed reduced pulses. CONCLUSIONS Balloon angioplasty of discrete native coarctation is effective in patients both younger and older than 3 months. However, thea rates of restenosis, aneurysm formation, and approach artery injury are higher in patients younger than 3 months old when compared with patients aged over 3 months. These complications should be considered when performing balloon angioplasty in patients less than 3 months of age.

Abstract
BACKGROUND The objectives of this study were to compare, in the current era, the immediate results, complications, and midterm outcomes obtained by surgical repair versus transcatheter treatment of coarctation of the aorta (CoA). METHODS The study was of retrospective nature and included 80 consecutive patients > or = 1 year old (mean age 12 +/- 10 years) treated for an isolated CoA in 4 university centers in Quebec between 1998 and 2004. Fifty patients underwent aortic angioplasty, with stent implantation in 19, and 30 had surgical repair. Immediate results, procedural complications, clinical events, and the incidence of aortic aneurysm at follow-up were compared between groups. RESULTS There were no differences between the 2 groups in clinical baseline characteristics. Percentage reduction in peak systolic pressure gradient across the coarctation was similar between the 2 groups (angioplasty 72% +/- 23% vs surgery 75% +/- 18%, P = .55). Procedure-related complications occurred more frequently after surgical repair compared with angioplasty (50% vs 18%, P = .005), and median hospitalization time was longer in the surgical than in the angioplasty group (7 vs 1 day, P < .001). At 38 +/- 21 months' follow-up, no patient in the surgical group and 16 patients in the angioplasty group had at least 1 aortic reintervention (0% vs 32%, P < .0001). The presence of an aortic aneurysm was diagnosed more frequently in the angioplasty group compared with the surgical group (24% vs 0%, P = .01). CONCLUSION Aortic angioplasty provided comparable immediate hemodynamic results to surgery, with reduced morbidity and hospitalization length for the treatment of CoA in patients > or = 1 year old. However, angioplasty was associated with a higher rate of reintervention and aneurysm formation at a mean follow-up of 3 years.

Abstract
BACKGROUND Stenting for aortic coarctation has been shown to be effective in the short term. The safety and longer term efficacy of transcatheter therapy, however, must be well established if the technique is to be widely accepted as an alternative to surgery. In order to determine the frequency, spectrum, and outcome of injury to the aortic wall caused by angioplasty or stenting of aortic coarctation, the nomenclature of mural injury in these patients must be adapted to the conditions of transcatheter therapy. METHODS AND RESULTS Between 1989 and July 2005, we inserted stents in 153 patients with aortic coarctation, their median age being 15.8 years. Prior aortic interventions had been performed in 98 patients, and preexisting aneurysms were observed in 19. Stenting resulted in a significant reduction of the gradient across the site of coarctation, from a median of 30 millimetres of mercury to zero (p less than 0.001), with a residual gradient within the aortic arch of 20 millimetres of mercury or more in 5% of patients. Acute injuries to the aortic wall, other than therapeutic tears, were observed in 3 patients (2%), none of whom required surgery. At median follow-up of 2.5 years, this being more than 5 years in 30 patients, 4 patients had died, albeit none from complications relating to stenting or catheterization. Acute injuries to the aortic wall did not progress, and new aneurysms were observed in 6% of patients subsequent to follow-up imaging. Stent fractures, and jailed or partially covered brachiocephalic vessels, were observed in 12, and 49, patients, respectively, but did not result in haemodynamic or embolic complications. CONCLUSIONS Stenting for aortic coarctation results in consistent relief of the gradient, and few serious complications in the short and intermediate term. Serious injuries to the aortic wall are uncommon in our experience, and can be minimized with a focus on technical measures, such as pre-dilation before stenting.

Abstract
Surgery had been the traditional treatment for native coarctation of the aorta, one of the most common cardiovascular congenital malformations. As a less invasive mode of treatment, balloon angioplasty has emerged as an alternative to surgery but has not gained universal acceptance due to its rates of restenosis secondary to vessel recoil and concerns over aortic wall injury resulting in aneurysm formation. To overcome these problems, endovascular stents were introduced in the management of this condition. The early- and intermediate-term results are encouraging, with low rates of restenosis and complications. In this article, the authors review the current evidence on coarctation stenting and discuss future trends in this area.

Abstract
We present clinical follow-up of a 20-year-old male with an aortic aneurysm secondary to aortic coarctation. The diagnosis of aortic aneurysm secondary to aortic coarctation was made in 1997. The patient did not agree to undergo any invasive or therapeutic procedures at that time. He presented to an emergency unit with severe chest pain after chest trauma obtained during judo exercises in 1998. Two-dimensional echocardiography showed bicuspid aortic valves, an ascending aortic aneurysm 6 cm in diameter with an intimal flap and false lumen, aortic coarctation distal to the left subclavian artery, and aortic insufficiency secondary to annular dilatation. Type II aortic dissection was confirmed by transesophageal echocardiography, which showed the dissection was confined to the ascending aorta. The dissection extended to the beginning of the arcus aorta. Following stabilization of the patient's clinical condition, balloon coarctation angioplasty was performed to reduce afterload and hypertension and to facilitate femoral artery cannulation for cardiopulmonary bypass. Surgical procedures included resection of the aortic valve and prosthetic valve implantation, resection of the ascending aorta, and interposition of a 22 mm Hamashied tubular vascular graft. At a follow-up visit 6 years later, the patient reported being easily fatigued and having palpitations. He had been suffering from hemolytic anemia and mild renal function impairment. Cardiac catheterisation and angiography showed a 40 mmHg gradient due to kinking of the aortic graft and no gradient at the coarctation site. We postulated the kinking of the aortic vascular graft may be related to an inappropriate vascular graft length. We also thought that the severe hemolysis was attributable to the disturbance of blood flow by a jet of blood at the site of the kinking aortic vascular graft. A second operation was performed because the renal function of the patient had decreased progressively and hemolysis symptoms increased. After the second operation, hemolysis on peripheral blood smears had disappeared and renal function had shown progressive improvements.

Abstract
We report our experience with the use of covered stents for the management of coarctation of the aorta. From December 2001 to March 2004, nine patients (seven males; median age, 31 years; mean weight, 65 +/- 15 kg) underwent implantation. Indications included critical or atretic native coarctation (n = 4), patients >50 years of age (n = 2), associated patent ductus arteriosus (n = 1) or adjacent aneurysm (n = 1), and the presence of a circumferential fracture within a previously implanted stent (n = 1). The covered balloon-expandable Cheatham-Platinum stent and the self-expandable stent graft Braile were employed. Adequate implantation was observed in all patients. Gradients were reduced from 54 +/- 14 to 3 +/- 8 mmHg and the coarctation site increased from 2.4 +/- 2.9 to 15.9 +/- 4.3 mm. The patent ductus arteriosus was immediately closed and the aneurysm excluded. Two patients >35 years with aneurysmal ascending aorta and metallic aortic prosthesis had aneurysm formation at follow-up, with one undergoing aneurysm exclusion using a Braile stent. Although covered stents are useful in the management of selected patients with coarctation, aneurysm formation may still occur in patients with markers of aortic wall weakness. Refinements in the deployment technique and/or the stent design are needed to eliminate this risk.

Abstract
Surgical repair has a dramatic impact on the prognosis of aortic coarctation. However, in many units, endovascular repair by balloon angioplasty or stenting has become the primary treatment. Short-term results are excellent but there are few data on later outcome. Care needs to be exercised in patient selection, and although major complications are rare, when they do occur they may be devastating. This article reviews our current practice for the assessment selection and follow-up of these patients.

Abstract
BACKGROUND Use of balloon angioplasty or stent implantation has been reported to be effective in relieving coarctation of the aorta. However, restenosis frequently occurs after balloon angioplasty for native aortic coarctation in small infants, and sometimes develops after stent implantation because of vessel growth. The causes of restenosis remain uncertain. The purpose of this study was to assess the histologic differences in vascular responses to angioplasty using conventional balloon, radiofrequency thermal balloon (RFTB), or stent for experimental aortic coarctation. METHODS The authors surgically created an aortic coarctation model using 14 puppies. Angioplasty using conventional balloon, RFTB, or stent was performed 1 month after the initial operation. At the acute or chronic phase after angioplasty, the animals were killed and histologic studies were performed. RESULTS More vascular injuries were noted in the specimens from animals undergoing conventional angioplasty than in those with RFTB or stent. However, neointimal hyperplasia was seen more often after RFTB or stent because of the proliferation of smooth muscle cells from the tunica media, caused by secretion of growth factors. Apoptosis reached a peak 1-2 weeks after angioplasty, regardless of the type of intervention. CONCLUSIONS The authors conclude that angioplasty with RFTB or stent can provide relatively small injuries in the vessel wall for aortic coarctation, but care must be taken to prevent restenosis caused by intimal hyperplasia, because neointima hyperplasia is more frequent after RFTB or stent.

Abstract
OBJECTIVES To analyze the results of nonsurgical treatment of aortic coarctation and recoarctation by evaluating the results of each technique, and its complications and outcome. PATIENTS AND METHODS The results were as follows: 51 children underwent balloon dilatation due to recoarctation (86.5 %); two underwent dilation of a native coarctation (3.3 %) and six underwent stent implantation for recoarctation (10 %). Age ranged from 2 to 236 months (109 +/- 63.45 months) with a follow-up of between 1 and 156 months (38.87 +/-32.96 months). RESULTS The mean predilatation gradient in children with recoarctation was 34 +/- 11.62 mmHg, which decreased to 11 +/- 5.38 mm Hg (p < 0.0001). In 12 patients (20.3 %) effective dilatation was not achieved. The size of the stenosis was 6.7 +/- 2.35 mm predilatation, which increased to 9.3 +/- 3.10 mm (p < 0.0001) after dilatation with a percentage increase of 50.97. There were very few complications. Six children required subsequent redilatation. The experience with stent showed a mean gradient of 32.83 +/- 10.62 mm Hg, which decreased to 7.3 +/- 3.8 mm Hg (p < 0.0001) with a balloon/stenosis ratio of 1.94. CONCLUSIONS We conclude that the interventionist technique is highly effective in both native coarctation and recoarctation in the short term, as well as subsequently, with very few complications. The stent technique produces equally good results in older children, which is promising for the future.

Abstract
An adult male experienced severe chest pain during stenting of a native aortic coarctation. He also developed the postcoarctectomy syndrome with paradoxical hypertension and abdominal pain. Our hypothesis suggests that sudden interruption of large collateral blood flow caused acute chest wall muscle ischemia, rhabdomyolysis, and severe chest pain.

Abstract
The standard treatment of coarctation of the aorta is surgical. In the last 2 decades, however, treatment by catheter intervention has become more widespread, using either balloon angioplasty or primary stent implantation. Balloon angioplasty was originally used for recurrent coarctation after surgical repair but has now been shown equally effective for unoperated coarctation. The procedure produces a satisfactory gradient reduction in approximately 80% of patients, with transverse arch hypoplasia the main predictor of poorer outcome. Rates of restenosis and aneurysm formation are less than 10%. Primary stent implantation has been suggested as an option potentially superior to angioplasty alone. Stent implantation limits elastic recoil and potentially reduces aneurysm formation by reducing the amount of balloon stretch required. The incidence of suboptimal gradient reduction is low, probably 5% or less, as is the rate of restenosis. Aneurysm formation, vascular complications, and stent migration also occur in less than 5%. Catheter interventions are now an established treatment strategy for coarctation, with a good success rate and safety profile. The outcome for native and recurrent coarctation appears similar. The authors believe that for most adult patients with coarctation of the aorta, catheter intervention should be offered as initial therapy.
