Regional Arch Measurements Differ Between Imaging Modalities in Infants With Aortic Coarctation. Ann Thorac Surg 2024; 118:209-215. [PMID: 38072352 DOI: 10.1016/j.athoracsur.2023.11.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 10/24/2023] [Accepted: 11/20/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Aortic arch measurements provide a framework for surgical decision-making in neonatal aortic coarctation, specifically in the determination of approach for arch repair by lateral thoracotomy vs median sternotomy. The purpose of this study was to evaluate our experience with transthoracic echocardiography (TTE) and computed tomography angiography (CTA) in the preoperative evaluation of infants with aortic coarctation, specifically comparing arch dimensions as a function of imaging modality. METHODS Imaging data were reviewed for all infants undergoing surgical repair of aortic coarctation at our institution from 2012 to 2022. Infants with both TTE and CTA evaluations were included. Aortic measurements were compared at predefined anatomic regions including ascending aorta, proximal arch, distal arch, and isthmus. RESULTS During the study period, 372 infants underwent surgical coarctation repair; 72 (19.4%) infants had TTE and CTA arch evaluations preoperatively. Significant discrepancies between imaging modalities were defined by poor correlation coefficients and absolute measurement differences and were most prominent in the proximal aortic arch (R2 = 0.23 [-4.4 to 3.2 mm]) and isthmus regions (R2 = 0.11 [-4.2 to 1.7 mm]). Improved correlation was demonstrated in the ascending aorta (R2 = 0.63) and distal aortic arch (R2 = 0.54). CONCLUSIONS Significant variability exists between TTE- and CTA-derived aortic measurements in infants with coarctation, with proximal arch measurements demonstrating the poorest correlation. This anatomic location represents a commonly used arch region for the determination of approach for repair of neonatal aortic coarctation. Thus, these findings have important implications for current preoperative surgical decision-making paradigms and future prospective study to minimize the risk of residual or recurrent arch obstruction.

Abstract
BACKGROUND Although coarctation of the aorta without concomitant intracardiac pathology is relatively common, there is lack of guidance regarding aspects of its management in neonates and infants. METHODS A panel of experienced congenital cardiac surgeons, cardiologists, and intensivists was created, and key questions related to the management of isolated coarctation in neonates and infants were formed using the PICO (Patients/Population, Intervention, Comparison/Control, Outcome) Framework. A literature search was then performed for each question. Practice guidelines were developed with classification of recommendation and level of evidence using a modified Delphi method. RESULTS For neonates and infants with isolated coarctation, surgery is indicated in the absence of obvious surgical contraindications. For patients with risk factors for surgery, medical management before intervention is reasonable. For those stable off prostaglandin E1, the threshold for intervention remains unclear. Thoracotomy is indicated when arch hypoplasia is not present. Sternotomy is preferable when arch hypoplasia is present that cannot be adequately addressed through a thoracotomy. Sternotomy may also be considered in the presence of a bovine aortic arch. Antegrade cerebral perfusion may be reasonable when the repair is performed through a sternotomy. Extended end-to-end, arch advancement, and patch augmentation are all reasonable techniques. CONCLUSIONS Surgery remains the standard of care for the management of isolated coarctation in neonates and infants. Depending on degree and location, arch hypoplasia may require a sternotomy approach as opposed to a thoracotomy approach. Significant opportunities remain to better delineate management in these patients.

REVISTA DA ASSOCIACAO MEDICA BRASILEIRA (1992) 2024; 70:e20231626. [PMID: 38775513 PMCID: PMC11110970 DOI: 10.1590/1806-9282.20231626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 12/29/2023] [Indexed: 05/24/2024]
Abstract
OBJECTIVE This study aimed to compare the effectiveness of resection and extended end-to-end anastomosis between neonate and infant patients with coarctation. METHODS This study was designed retrospectively and included 41 neonate (<30 days) and infant (30 days to 1 year) patients who were operated on using the resection and extended end-to-end anastomosis technique for aortic coarctation. Preoperative aortic annulus diameters and Z scores, all aortic arch diameters and Z scores, the presence of hypoplastic aortic segment, and the presence of prematurity were reviewed in both groups. Subsequently, we investigated whether these parameters were statistically related to the residual gradient in the operation area, whether there was a need for early re-intervention, and what was the incidence of mortality in the early postoperative period. In addition, the aortic arch Z scores of the patients at 6 months postoperatively were examined. RESULTS While the mean age (p<0.001), body weight (p<0.001), and proximal arch Z score (p=0.029) were found to be significantly lower in the neonate group than in the infant group, the total length of the intensive care unit stay (p=0.013) and the total length of hospital stay (p=0.017) were found to be significantly higher. In addition, significant enlargement was detected in the proximal arch, distal arch, and isthmus segments in both patient groups. CONCLUSION The resection and extended end-to-end anastomosis is an equally effective technique that can provide a marked decrease in gradient in the coarctation area and a significant enlargement of the aortic arch segments in the early period after coarctation repair in both neonate and infant patients.

Abstract
A variety of surgical approaches exist to treat aortic coarctation in neonates and infants. Our institutional approach is designed to match the surgical approach to the individual anatomy of the patient. The objective of this study is to evaluate operative characteristics and outcomes of all neonates and infants who underwent surgical repair of coarctation of the aorta or hypoplastic aortic arch at University of Florida from 2006 to 2021, inclusive, either in isolation or with concomitant repair of atrial septal defect (ASD) and/or ventricular septal defect (VSD). A retrospective review was performed of 132 patients aged 0-1 year who underwent surgical repair of aortic coarctation or hypoplastic aortic arch between 2006 and 2021, inclusive, either in isolation or with concomitant repair of ASD and/or VSD. Patients were divided into two groups based on the surgical approach: Group 1 = Median Sternotomy and Group 2 = Left Lateral Thoracotomy. Continuous variables are presented as median (minimum-maximum); categorical variables are presented as N (%). The most common operative technique in Group 1 was end-to-side reconstruction with ligation of the aortic isthmus. The most common operative technique in Group 2 was extended end-to-end repair. Operative Mortality was one patient (1/132 = 0.76%). Transcatheter intervention for recurrent coarctation was performed in seven patients (7/132 = 5.3%). Surgical re-intervention for recurrent coarctation was performed in three patients (3/132 = 2.3%). From these data, one can conclude that a strategy of matching the surgical approach to the anatomy of neonates and infants who underwent surgical repair of aortic coarctation or hypoplastic aortic arch, either in isolation or with concomitant repair of ASD and/or VSD, is associated with less than 1% Operative Mortality and less than 3% recurrent coarctation requiring reoperation.

Abstract
Background: Coarctation of the aorta can be associated with significant hypoplasia of the aortic arch. In contrast to patch aortoplasty, ascending sliding arch aortoplasty uses viable autologous tissue for potential growth in children. We reviewed the mid- to long-term outcomes of this technique. Methods: Between 2002 and 2023, 28 patients underwent ascending sliding arch aortoplasty for the patients with coarctation of the aorta (n = 22) and interrupted aortic arch (n = 2). Four patients underwent previous surgical coarctation repair at other institutions. The median patient age and body weight were 28.5 months (3 weeks to 15.6 years) and 13.4 kg (3.7-70 kg), respectively. Results: Although one patient had a recurrent nerve injury postoperatively, there were no other major morbidities or mortalities. The last follow-up echocardiography demonstrated that the mean peak velocity improved from 3.9 ± 0.6 to 0.9 ± 0.8 m/s, and the pressure gradient improved from 63.6 ± 21.5 to 7.1 ± 7.7 mm Hg. The postoperative diameters of the ascending aorta, proximal arch, distal arch, and isthmus all increased significantly. The mean postoperative length of stay was 5.9 ± 2.1 days, and the median follow-up time was 7.3 years (10 days to 20.5 years). No reoperation or catheterization-based intervention was performed for residual coarctation. Conclusions: Ascending sliding arch aortoplasty is safe and effective for treating coarctation of the aorta with aortic arch hypoplasia. This technique is applicable for children ranging in size from neonates to older children (or adolescents), recurrent coarctation cases, and provides complete relief of narrowing by utilizing viable native aortic tissue.

Abstract
BACKGROUND The incidence of reintervention for aortic arch obstruction is 5% to 14% after coarctation or hypoplastic aortic arch repair and 25% after the Norwood procedure. Institutional practice review indicated higher than reported reintervention rates. Our aim was to assess the impact of an interdigitating reconstruction technique on reintervention rates for recurrent aortic arch obstruction. METHODS Children (<18 years) were included if they had undergone aortic arch reconstruction by sternotomy or the Norwood procedure. Three surgeons participated in the intervention with staggered rollout dates between June 2017 and January 2019, with the study ending December 2020 and review for reinterventions ending February 2022. Preintervention cohorts represented patients who underwent aortic arch reconstructions with patch augmentation, and postintervention cohorts represented patients who underwent an interdigitating reconstruction technique. Reinterventions by cardiac catheterization or operation were measured within 1 year of initial operation. Wilcoxon rank sum and χ2 tests were used to compare preintervention and postintervention cohorts. RESULTS Overall, 237 patients were included for participation in this study, with 84 patients in the preintervention cohort and 153 in the postintervention cohort. Patients undergoing the Norwood procedure represented 30% (n = 25) of the retrospective cohort and 35% (n = 53) of the intervention cohort. Overall reinterventions were significantly decreased after the study intervention from 31% (n = 26/84) to 13% (n = 20/153; P < .001). Reintervention rates were decreased for each intervention cohort: aortic arch hypoplasia (24% [n = 14/59] vs 10% [n = 10/100]; P = .019) and Norwood procedure (48% [n = 12/25] vs 19% [n = 10/53]; P = .008). CONCLUSIONS The interdigitating reconstruction technique for obstructive aortic arch lesions was successfully implemented and is associated with a decrease in reinterventions.

Abstract
Computed tomographic angiography (CTA) has been increasingly used for the evaluation of infants with aortic arch hypoplasia and coarctation of the aorta. The goals of this study were to compare echocardiographic and CTA findings in critical coarctation of the aorta, to evaluate each modality's influence on surgical approach for repair and determine if pre-operative measurements or surgical approach are associated with residual lesions/re-interventions. This was a single-center retrospective cohort study that included 85 neonates and infants who underwent repair of coarctation/arch hypoplasia by three months of age. Two groups were compared: patients with pre-operative echocardiograms only and patients with both echocardiogram and CTA evaluations. 44 (52%) patients received an echocardiogram and CTA, and 41 (48%) patients received an echocardiogram only. Patients in the CTA + echo group had smaller mitral valve and ascending aorta measurements (p = 0.01). When comparing CTA to echocardiogram measurements, the aortic valve annulus, ascending aorta, proximal and distal transverse arch, and isthmus were smaller on echo (p < 0.01). A smaller aortic valve annulus and aortic root as well as thoracotomy approach were associated with residual gradients/re-intervention (p < 0.01). Our study found that patients who underwent CTA preoperatively had smaller left-sided structures. Aortic measurements were smaller on echocardiogram when compared to CTA. Smaller left-sided structures proximal to the aortic arch and thoracotomy predicted the development of residual lesions/re-intervention. CTA is useful in the surgical planning for neonates with arch hypoplasia/coarctation and may help risk stratify for residual lesions/re-intervention.

Abstract
INTRODUCTION Surgical treatment of aortic coarctation in low-birth-weight (LBW) neonates is associated with risks of higher hospital mortality rates and recoarctation development in the long-term. The goal of our study was to compare the results of surgical treatment of aortic coarctation in LBW neonates and normal-weight patients, to identify predictors of recoarctation in the long-term among LBW patients. MATERIALS AND METHODS A retrospective study was performed to analyse the patients who had undergone resection of isolated aortic coarctation between 2005 and 2022. Overall analysis included 521 patients under the age of 30 days, 89 LBW patients and 432 patients with normal body weight. Propensity score matching (PSM) was performed at a ratio of 1:1 for the statistical adjustment of original patients' data in both groups. RESULTS All patients underwent standard resection of aortic coarctation with extended end-to-end anastomosis. Hospital mortality among LBW patients was 8% and in patients with normal weight the mortality amounted to 1% (p = 0.030). LBW patients were transferred to other hospitals more often than normal-weight patients who were more often discharged (p < 0.001). In the long-term, period mortality was not statistically significantly different (p = 0.801). The freedom from reoperation in the group of normal-weight children was 87%, whereas in the LBW patients the rate was 63% (log rank test, p = 0.104). In the multivariate regression model, the most significant risk factors for reoperation were as follows: preoperative inotropes administration (OR (95% CI) 4.369 (1.316-14.51)) and pressure gradient across aortic arch before discharge (OR (95% CI) 1.081 (1.014-1.153)). CONCLUSIONS Hospital mortality was higher among LBW patients (p = 0.030). There was a statistical trend of differences in reoperation rates: in the long-term among LBW patients, a higher reintervention probability remains. Moreover, the LBW group initially had more severe clinical condition in terms of cardiac failure and impaired renal function. Factors associated with the risk of recoarctation were preoperative inotropes infusion and pressure gradient across aortic before discharge.

Abstract
The aim. This study aims to determine the reintervention rate in infantsundergoing aortic arch repair and to analyze risk factors and evaluate the results of reinterventions.
Materials and methods. This retrospective study examines 445 infants with aortic arch hypoplasia who under-went aortic arch reconstruction between 2011 and 2019. The study included only patients with two-ventricle physiology and subsequent two-ventricle repair. Techniques for primary repair included extended end-to-end anastomosis (n = 348), end-to-side anastomosis (n = 611), autologous pericardial patch repair (n = 16).
Results. The overall mortality in the entire study group was 3.3 %. Follow-up period ranged from 1 month to 9.4 years (mean 2.8 ± 2.5 years). Restenosis at the site of aortic arch repair was identiϐied in 47 (10.5 %) patients. Of these, 12 patients underwent surgical reconstruction of the aortic arch, 27 patients underwent balloon angioplasty, and in 8 patients both methods were used. Freedom from reintervention was 89.4 % at 1-year follow-up and 87.5 % at 4-year follow-up. The most determining factorsfor restenosis were related to hypoplastic proximal aortic arch and body weight less than 2.5 kg.
Conclusions. Surgical treatment of aortic arch hypoplasia in newborns and infants is effective and shows good immediate and long-term results. Anatomical correction of reobstruction at the level of the aortic arch is safe with both endovacular and surgical methods with low mortality and incidence of repeated interventions. Identified risk factors for mortality and recurrent aortic arch interventions help to improve the treatment of aortic arch hypoplasia in patients under 1 year of age.

Influence of Bovine Arch Anatomy on Surgical Outcomes of Coarctation of the Aorta. Pediatr Cardiol 2022; 44:933-939. [PMID: 36538051 DOI: 10.1007/s00246-022-03072-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Accepted: 12/05/2022] [Indexed: 12/24/2022]
Abstract
This study aimed to evaluate the outcome of coarctation of the aorta (CoA) repair with a special interest in bovine arch anatomy. Fifty-six patients who underwent CoA repair between 2010 and 2021 were included in this retrospective study. Of these, 11 patients had bovine arch anatomy. Surgical outcomes were reviewed. Computed tomography was used to analyze aortic arch geometry for all cases preoperatively. The gap between anastomotic sites was calculated at the linear region of the lesser curvature of the aortic arch between the distal ascending aorta and the proximal descending aorta. CoA repair was performed at a median age of 39 days (median body weight 3.3 kg). Thirty-two patients underwent extended direct anastomosis, 22 patients underwent direct anastomosis, and two patients underwent lesser curvature patch augmentation. The median follow-up period was 47 months. There were no early deaths. In patients who underwent direct and extended direct anastomosis, nine recoarctation and one left pulmonary venous obstruction events occurred. Moreover, freedom from these adverse events was 81% in normal arch and 50% in bovine arch patients at 10 years (P = 0.04). Two patients with a bovine arch anatomy who underwent lesser curvature patch augmentation had good outcomes. The distal arch was narrower and longer, and the gap between anastomotic sites was longer in patients with a bovine arch anatomy than with a normal arch (P < 0.01). In CoA with a bovine arch anatomy, the gap between anastomotic sites was long. This adversely influenced the outcomes of the CoA repairs.

Abstract
BACKGROUND Treatment of tubular hypoplasia of the aortic arch (THAA) associated with aortic coarctation (CoA) remains controversial. We aimed to evaluate growth of unrepaired hypoplastic proximal aortic arches (PAAs) after surgical repair for CoA. METHODS Preoperative and follow-up echocardiographic images of 139 patients who underwent CoA repairs from 2005 to 2012 were reviewed. THAA was defined as PAA z-score <-3 and non-THAA group z-score ≥-3. Reintervention rates due to aortic obstruction were assessed using competing risk models and diameters of the aorta were compared with Mann-Whitney U tests. RESULTS Fifty patients (36%) had THAA and 89 (64%) had non-THAA. The survival rate was 94% at 10 years. The overall reintervention rate at 10 years was 9% in the THAA group and 16% in the non-THAA group (P = .54). The catheter reintervention rate at ten years was 2% in the THAA group and 16% in the non-THAA group (P = .031). The surgical reintervention rate at ten years was 7% in the THAA group and 0% in the non-THAA group (P = .016). All 4 patients who required surgical reintervention were in the THAA group and 3 patients with PAA obstruction had preoperative PAA z-scores -3.6, -4.2, and -4.3. Follow-up echocardiograms showed PAA catch-up growth in the THAA group compared with the non-THAA group (preoperative z-score of -3.6 vs -2.3, and at 7 years of -1.1 vs -1.2; P < .001). CONCLUSIONS Unrepaired PAA hypoplasia grows after CoA repair. Reintervention rates were comparable between groups but those with THAA had higher surgical reintervention rates.

Abstract
OBJECTIVES The outcomes of the single-stage surgical repair of aortic arch hypoplasia (AAH) and/or coarctation of the aorta (CoA) associated with ventricular septal defect (VSD) remain controversial, especially in a lower middle-income country. This study reports the results of a single-stage repair protocol at our institution for AAH/CoA with VSD using selective cerebral perfusion. METHODS This retrospective study included 100 consecutive patients who underwent single-stage repair via median sternotomy using selective cerebral perfusion for AAH/CoA with VSD from July 2010 to March 2017. RESULTS The patients consisted of 65 males and 35 females. The median age of the patients was 67 days (range 4-2266 days); the median weight was 3.8 kg (range 2.1-15 kg). The average cardiopulmonary bypass time was 132 ± 28 min, the aortic cross-clamp time was 92 ± 23 min and the selective cerebral perfusion time was 33 ± 10 min. The survival rate of all patients was 94.7 ± 2.3%, with an in-hospital mortality of 5% and no late mortality at a median follow-up of 37 months (range 4-96 months). Four patients required reoperation due to recoarctation. The overall event-free survival rate following surgery was 87.1%. The median pressure gradient across the anastomosis at the last follow-up was 8.3 ± 2.8 mmHg. Multivariate logistic regression analysis revealed proximal aortic arch obstruction as a predictor of mortality (odds ratio = 3.8). The aortic isthmus diameter was identified as a predictor for reintervention by Cox regression (hazard ratio = 6.7). CONCLUSIONS Single-stage repair for AAH/CoA with VSD is safe and feasible in a developing country.

Evaluating the severity of aortic coarctation in infants using anatomic features measured on CTA. Eur Radiol 2020; 31:1216-1226. [PMID: 32885294 DOI: 10.1007/s00330-020-07238-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Revised: 06/26/2020] [Accepted: 08/27/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVES A machine learning model was developed to evaluate the severity of aortic coarctation (CoA) in infants based on anatomical features measured on CTA. METHODS In total, 239 infant patients undergoing both thorax CTA and echocardiography were retrospectively reviewed. The patients were assigned to either mild or severe CoA group based on their pressure gradient on echocardiography. They were further divided into patent ductus arteriosus (PDA) and non-PDA groups. The anatomical features were measured on double-oblique multiplanar reconstructed CTA images. Then, the optimal features were identified by using the Boruta algorithm. Subsequently, the coarctation severity was classified using linear discriminant analysis (LDA). We further investigated the relationship between the anatomical features and re-coarctation using Cox regression. RESULTS Four anatomical features showed significant differences between the mild and severe CoA groups, including the smallest aortic cross-sectional area indexed to body surface area (p < 0.001), the narrowest aortic diameter (CoA diameter) indexed to height (p < 0.001), the diameter of the descending aorta at the diaphragmatic level (p < 0.001) and weight (p = 0.005). With these features, accuracy of 88.6% and 90.2%, sensitivity of 65.0% and 72.1%, and specificity of 92.9% and 100% were obtained for classifying the CoA severity in the non-PDA and PDA groups, respectively. Moreover, CoA diameter indexed to weight was associated with the risk of re-coarctation. CONCLUSIONS CoA severity can be evaluated by using LDA with anatomical features. When quantifying the severity of CoA and risk of re-coarctation, both anatomical alternations at the CoA site and the growth of the patients need to be considered. KEY POINTS • CTA is routinely ordered for infants with coarctation of the aorta; however, whether anatomical variations observed with CTA could be used to assess the severity of CoA remains unknown. • Using the diameter and area of the coarctation site adjusted to body growth as features, the LDA model achieved an accuracy of 88.6% and 90.2% in differentiating between the mild and severe CoA patients in the non-PDA group and PDA group, respectively. • The narrowest aortic diameter (CoA diameter) indexed to weight has a hazard ratio of 10.29 for re-coarctation.

Abstract
BACKGROUND After surgical repair of aortic coarctation (CoA) there is a risk for restenosis (reCoA), particularly in the first year of life. This study aimed to identify reCoA risk factors by analyzing postoperative predischarge echocardiograms. METHODS This was a retrospective analysis of echocardiograms of children born operated on for CoA in Sweden in 2011 to 2017. RESULTS A total of 253 children were included. Median age at surgery was 10 days; median follow-up was 4.6 years. Risk for restenosis occurred in 34 patients (13%; 74% by 6 months and 91% by 12 months). We generated 2 reCoA risk models applying aortic dimensions and the respective Z-scores combined with surgical and demographic factors. We defined reCoA risk categories as low (≤10%), moderate (11% to 29%), moderate to high (30% to 49%), or high (≥50%). Patients with either isthmus of 3.3 mm or less (1- and 5-year event-free survival of 38% and 32%, respectively) or isthmus Z-score of -2.8 or less with a weight at surgery of less than 4.4 kg (1- and 5-year event free survival of 21% and 16%, respectively) were at highest risk for reCoA. Conversely, patients at low risk had isthmus greater than 3.7 mm and distal aortic arch greater than 3.5mm (1- and 5-year event free survival of 97% and 97%, respectively), and isthmus and proximal aortic arch Z-score greater than -2.8 or operative weight greater than 4.4 kg with an isthmus Z-score of -2.8 or less (1- and 5-year event-free survival of 97% and 97%, respectively). CONCLUSIONS Risk for reCoA can be predicted based on postoperative predischarge echocardiographic variables combined with surgical and demographic factors. We suggest tailoring follow-up intervals individually according to the predicted reCoA risk.

Abstract
Aortic coarctation is a common congenital heart defect that often requires correction at a young age. Currently, success is defined by the achievement of a durable repair with low morbidity and mortality. We sought to systematically review the literature on risk factors for recoarctation and mortality in infants submitted to aortic arch coarctation repair under 1 year of age. PubMed and Scopus were searched for studies reporting risk factors for recoarctation and mortality from January 1989 to August 2019. Among the 1038 retrieved articles, 18 met the inclusion criteria, with a total of 2891 patients. The extracted risk factors for recoarctation were comprehensively summarized in the following categories: demographic variables, associated anomalies, clinical and repair variables, and morphometric variables. Younger age and lower weight were weak determinants of need for reintervention, while smaller aortic arch was a strong predictor of recoarctation. While balloon angioplasty is a clear risk factor for arch restenosis, the chosen surgical technique is not a strong risk factor. Associated minor cardiac anomalies and lower weight at surgery were important risk factors for death. Younger and smaller infants are at increased risk for adverse outcomes when submitted to aortic arch coarctation repair. This is particularly important when associated with smaller arch morphology. Strategies to improve the management of these patients may play a key role in improving their outcomes. Notably, surgical technique was not a strong predictor of recoarctation and mortality, suggesting that the choice of one over the other should be tailored.

Abstract
OBJECTIVES The main challenge of aortic coarctation (CoA) repair in infants is to obtain durable results without morbidity. We aimed to describe predictors of aortic arch reintervention after aortic CoA repair. METHODS Between January 2000 and March 2014, we retrospectively included consecutive infants with isolated CoA or CoA with ventricular septal defect (CoA + VSD) who had surgical repair of the aortic arch before 3 months of age. RESULTS Five hundred and thirty patients were included: 308 (58%) patients had isolated CoA and 222 (42%) patients had CoA + VSD. Three hundred and eighty-five patients (72.6%) had CoA repair, 51 patients (9.6%) had CoA repair with closure of VSD and 94 patients (17.8%) had CoA repair with pulmonary artery banding. Mean age at operation was 13 ± 1.6 days, with 294 patients (55.5%) operated on before 2 weeks. Median follow-up was 7.57 years. Sixty-one patients (11.5%) needed reintervention on the aortic arch. Freedom from aortic arch reintervention was 90% at 1 year and 88.5% at 5 years. Proportions of aortic arch reintervention were similar in the different surgical strategy groups (P = 0.80). However, in patients receiving prostaglandin E1 (PGE1), the end-to-end repair was at higher risk of recoarctation compared to the extended end-to-side repair (P = 0.033). The risk factors of aortic arch reintervention were age at repair <15 days (P = 0.034) and the need for PGE1 infusion at surgery (P = 0.0043). CONCLUSIONS CoA repair in young infants has an overall good outcome. The use of PGE1 may modify the aortic arch anatomy and mask the boundaries of the resection to be performed. PGE1 treatment should be studied more specifically in another study to improve preoperative management.

Abstract
OBJECTIVES Surgical repair of coarctation of the aorta (CoA) is often possible through left thoracotomy and without the use of cardiopulmonary bypass. Recent studies reporting the outcome after CoA repair through left thoracotomy are limited. Therefore, the aim of this study is to evaluate the results of CoA repair through left thoracotomy in children who were operated on in our centre over the past 21 years. METHODS From January 1995 to December 2016, 292 patients younger than 18 years underwent primary CoA repair through left thoracotomy at our 2 institutions. Peri- and postoperative data and follow-up data collected from our hospital and the referring hospitals were retrospectively reviewed. RESULTS Median age at operation was 64 days (range 2 days-17 years). Most patients underwent the resection of the CoA followed by an (extended) end-to-end anastomosis (93%). Six patients died perioperatively and 2 more patients died during the follow-up, of which 7 patients had other major comorbidities. Actuarial survival was 97% at 5 years, 96% at 10 years and 96% at 15 years. Second arch interventions due to recoarctation were performed in 9.9% (n = 29) of patients, consisting of balloon dilatation in all but 2 patients. Recoarctation occurred significantly more often after initial repair in the neonatal period (21%) and could occur as late as 14 years after initial surgery. There were 7 re-recoarctations, and 14% of patients were on hypertensive medication during the follow-up. CONCLUSIONS Repair of CoA through left thoracotomy is a safe procedure with low rates of mortality. The long-term follow-up is necessary due to the significant risk of recoarctation requiring reintervention.

Abstract
A bovine arch is the most common aortic arch variant, characterized by a common origin of the innominate artery and the left common carotid artery. Data have shown that children with bovine arch anatomy and coarctation are at a significantly higher risk of recoarctation following coarctation repair. This study aims to explain the higher coarctation rates, assess the branching of the arch vessels, understand their embryologic origins, and delineate the patterns of displacement of the arch vessels in bovine versus normal anatomy. This retrospective study reviewed the medical records of 178 infants ( < 1-year-old) who had a chest CT Angiogram (58) or CT (120) at our institution between 2007 and 2017. Multiplanar reconstruction software was used to obtain the best image plane to display the sinotubular junction, innominate artery, left common carotid artery, and left subclavian artery. We measured the distances between the branches as HV1, HV2, and HV3. All distances were standardized to body surface area and sinotubular junction diameter, which is a novel method. Bovine arches were found in 32.6% of patients. The total arch length of both arch anatomies was similar. HV3 is longer in bovine arches. HV1 + HV2 and HV2 + HV3 are longer in the normal arches than the bovine arches. The left subclavian artery moves proximally, and the innominate artery moves slightly distally to form the bovine arch and decreasing the clamping distance for coarctation repair. Aortic arch distances were similar when standardized to either sinotubular junction diameter and body surface area.

Abstract
Patients who undergo coarctation repair during infancy have excellent early survival but long-term survival is unknown. We aimed to describe the long-term survival of patients with coarctation repaired during infancy and determine predictors of mortality. We performed a retrospective cohort study using data from the Pediatric Cardiac Care Consortium for patients with coarctation who underwent surgical repair before 12 months of age between 1982 and 2003. Long-term transplant-free survival was obtained by linkage with the National Death Index and the Organ Sharing Procurement Network. Kaplan Meier survival plots were constructed, and univariate and multivariable analyses were performed to determine predictors of mortality. We identified 2,424 coarctation patients who met inclusion criteria. At 20 years postoperatively, 94.5% of all patients and 95.8% of those discharged after initial operation remained alive, respectively. Significant multivariable predictors of mortality included surgical weight <2.5 kg (hazard ratio [HR] 3.70, 95% confidence interval [CI] 2.19 to 6.24), presence of a genetic syndrome (HR 2.40, 95% CI 1.13 to 5.10), and repair before 1990 (HR 1.91, 95% CI 1.09 to 3.34). None of the other factors examined including age at repair, gender, coarctation type, or surgical approach were found to be statistically significant. Over half of the deaths were due to the underlying congenital heart disease or other cardiovascular etiology. Overall long-term survival of patients who undergo coarctation repair during infancy is excellent. However, patients do experience small continued survival attrition throughout early adulthood. Ongoing monitoring of this cohort is necessary to assess late mortality risk.

Abstract
BACKGROUND One of the congenital heart defects which can cause severe cardiac symptoms and cardiac failure in early childhood and neonatal duration is coarctation of aorta. Balloon angioplasty or surgical approach could be done for management of these defects. This study aimed to evaluate the efficacy and safety of coarctation stenting to improve the condition of these patients. METHODS Five patients with severe coarctation of aorta participated in this study. Balloon angioplasty performed for these patients initially. Each of five patients had a gradient decline after the initial balloon angioplasty, and againing gradients increased during the follow-up; then, they were treated by implanting a stent. We used Cook Formula stents for these patients. RESULTS The pressure gradient decreased in all 5 patients with maximum and minimum reduction of 55 and 35 mmHg; and we had not severe complication during or after the procedure and during the follow-up period. CONCLUSION Performing a stent in selected small children and infants that have sever and symptomatic coarctation of aorta can be effective and safe in improving patients' clinical state, and preventing surgery.

Abstract
Although various modalities are currently in use to define pediatric aortic arch hypoplasia (AAH), there is little uniformity among them. We aimed to determine the inter-rater strength of agreement of the nomograms in a survey of patients less than 1 year old, who had undergone coarctation of the aorta (CoA) repair with or without AAH. This retrospectively designed study comprised of 105 patients with CoA, who had been evaluated between 2008 and 2018 by means of a computed tomography angiogram. Through re-estimation of the aortic arch segmental diameters, the z scores were calculated using three nomograms (Cantinotti, Pettersen, Lopez). Along with a t test and Pearson's correlation coefficient, a linear regression analysis, Bland-Altman plots, and Cohen's kappa k value were used to evaluate inter-rater strength of agreement. The mean age and weight of the cohort was 73.3 ± 81.2 days and 4.2 ± 1.6 kg, respectively. Sixty-four (61%) patients were neonates. The z scores of the nomograms for each aortic arch segment were significantly different. Although there was a significantly positive correlation between the nomograms with their related aortic arch diameter, the differences in z scores revealed considerable deviations in the scatter plot diagrams. The mean difference of z scores was significantly different from the testing value of zero, which was also presented in Bland-Altman plots. None of the comparisons reached a kappa k value of > 0.9. The current nomograms do not reveal an acceptable level of agreement for the definition of the AAH. The question is which modality to rely on when deciding on the surgical approach and technique of CoA repair to address the hypoplastic aortic arch segment. Decisions about the surgical approach and the technique of repair warrant a reliable definition of AAH. It is high time that a consensus is reached in this regard.

Abstract
Coarctation of aorta (CoA) is a congenital heart disease that can lead to heart failure during infancy and neonatal period. Several treatments have been proposed for this disease, including surgery and balloon angioplasty. The experiences of using stents in small infants or neonatal patients are very low. In this article, we report a 3 months old age infant who after balloon angioplasty, his CoA symptoms had return and stenting of CoA was performed for him.

Abstract
OBJECTIVES The aim of the present study was to evaluate procedural risk factors, incidence and timing of reintervention because of recurrent aortic coarctation in children. METHODS The study cohort consisted of 304 patients with isolated coarctation: 251 underwent surgery and 53 were treated percutaneously (40 balloon angioplasty, 13 stent) at the Helsinki Children's Hospital in 2000-2012. Characteristics, intervention and reintervention data were retrospectively collected from clinical records until 2014 (median follow-up 7.9 years). Age- and sex-matched comparisons between the treatment groups were performed in 86 patients (surgery n = 43, percutaneous n = 43). RESULTS Forty of the 251 (16%) patients after surgery, 9/40 (23%) patients after balloon angioplasty and 4/13 (31%) patients after stent placement underwent a reintervention after a median time of 3.4, 11.7 and 19.5 months (P < 0.05), respectively. In the surgery group, all reinterventions occurred in children operated on ≤12 months of age and were related to lower body weight and smaller dimensions of the aorta. In the balloon angioplasty group, a higher post-procedure systolic arm-leg blood pressure gradient was associated with reintervention. After stent placement, three-fourths of the reinterventions were performed in a planned postinterventional catheterization. In the age- and sex-matched comparisons (median 5,7 years, range 0,5-17,6), post-procedure blood pressure gradients were higher (mean 10 vs 4 mmHg, P = 0.03), and reinterventions were more common (28%, 95% confidence interval 17-43 vs 2%, 95% confidence interval 0-12) in the percutaneous group compared to the surgery group. CONCLUSIONS Reinterventions after surgery in neonates were relatively common. In older children, percutaneous treatment carried a higher risk of reinterventions, which were mainly related to residual coarctation after primary treatment.

Abstract
Background: Several techniques have been described to correct coarctation associated with distal arch hypoplasia. However, in neonates, residual gradients are frequently encountered and influence long-term outcome. We reviewed our experience with an alternative technique of repair combining carotid–subclavian angioplasty and extended end-to-end anastomosis. Methods: From 1998 through 2014, 109 neonates (median age, 9 days) with coarctation and distal arch hypoplasia (n = 106) or type A interrupted aortic arch (n = 3) underwent repair using this technique. Thirty patients had isolated lesions (group 1), 44 associated ventricular septal defect (group 2), and 35 associated complex cardiac lesions (group 3). Median follow-up was 98 months. Results: Repair was performed via left thoracotomy in 97%. There was one procedural-related death (0.9%) and overall five patients died during index admission (4.6%). Ten deaths were recorded at follow-up. Actuarial five-year survival was 86% (100% in group 1, 91% group 2, and 66% in group 3). Recurrent coarctation (clinical or invasive gradient >20 mm Hg) developed in 15 patients, all but 2 successfully treated by balloon dilatation. Freedom from any reintervention (dilatation or surgery) at five years was 86%. Only two patients were on antihypertensive drugs at last follow-up. Conclusions: This combined technique to correct distal arch hypoplasia and isthmic coarctation results in low mortality and acceptable recurrence rate. It preserves the left subclavian artery and allows enlargement of the distal arch diameter. Late outcome is excellent with very low prevalence of late arterial hypertension.

Abstract
OBJECTIVES The aim of our prospective randomized study was to compare modified reverse aortoplasty (MRA) and extended end-to-end anastomosis (EEA). METHODS We have assessed the operative correction results in 54 infants with coarctation of the aorta and distal aortic arch hypoplasia who underwent primary repair in our institute between July 2013 and February 2014. All of the patients were <12 months old when they had the operation. Patients were randomly assigned to 2 arms: modified reverse subclavian flap angioplasty (MRA group; n = 27) or extended end-to-end anastomosis (EEA group; n = 27). RESULTS We found a significant difference in residual arterial hypertension between the groups: 2 (7.7%) patients in the MRA group and 8 (30.8%) patients in the EEA group, respectively (P = 0.03). Risk factors for arterial hypertension were precoarctation area rigidity and endocardial fibroelastosis. During the last follow-up visit, recoarctation was observed in 1 (3.8%) patient in the MRA group and in 2 (7.7%) patients in the EEA group, respectively (P = 0.50). Cox regression analysis showed that the only risk factor for recoarctation was the patient's low weight before surgery [odds ratio (95% confidence interval) 0.016 (0.001-0.51), P = 0.047]. An aortic aneurysm developed in 2 (7.7%) patients in the MRA group; however, no significant difference was found between the groups (P = 0.15). CONCLUSIONS The results of surgical repair of coarctation of the aorta using modified reverse subclavian flap angioplasty and extended anastomosis were comparable in mortality rates and early postoperative complications. Nevertheless, MRA may be beneficial in reducing residual arterial hypertension at the mid-term follow-up visit.

Abstract
BACKGROUND Coarctation of the aorta can be associated with hypoplasia of the proximal transverse aortic arch. One approach to manage this condition is via left thoracotomy and extended end-to-end anastomosis with the expectation that the proximal arch will grow over time. Our preferred approach is to augment the aorta via midline sternotomy. We hypothesized that this approach is safe, durable, and allows reliable growth of the aorta. METHODS We identified the records of patients with biventricular anatomy who had coarctation of the aorta, hypoplasia of the proximal transverse arch, and no other cardiac lesion that would mandate cardiopulmonary bypass use and midline sternotomy. The records of 62 such patients operated on between 2005 and 2016 were retrospectively reviewed. Patient demographics, clinical variables and outcome data were collected and analyzed using SAS 9.4. Data are presented as median (interquartile range [IQR]). RESULTS Sixty-two patients (23 girls [37%]) underwent repair at 10 (IQR, 5 to 21) days of life. Forty-nine (79%) patients were on prostaglandin infusion to maintain ductal patency. Fifteen (24%) patients presented in shock with end organ dysfunction, 17 (27%) were on inotropes, and 26 (42%) were mechanically ventilated. The proximal transverse arch was 41% (IQR, 34% to 47%) of the size of ascending aorta as measured by echocardiography (z-score, -5 [IQR, -5.8 to -4.3]). Following median sternotomy, repair was carried out on cardiopulmonary bypass (41 [IQR, 37 to 47] minutes). The arch was reconstructed with (n = 26 [42%]) or without (n = 36 [58%]) coarctectomy usually using homograft patch aortoplasty (n = 58 [94%]). In all but 2 patients, repair was undertaken with circulatory arrest (27 [IQR, 22 to 31] minutes). Patients were extubated 4 (IQR, 3 to 5) days later and discharged home in 12 (IQR, 8 to 18) days. There was no mortality, and 8 morbidity events (3 recurrent nerve injury, 2 chylothorax, 1 phrenic nerve injury, 1 seizure, and 1 superficial wound infection) in 7 (11%) patients. All patients are alive at 41 (IQR, 11 to 64) months of follow-up. Reintervention was required in 6 (10%) patients (5 catheter based and 3 surgical) for recurrent distal coarctation. Reintervention-free survival at 1, 3, and 5 years was 87%. Only 1 child was currently on antihypertensive therapy, and all were in New York Heart Association functional class I symptoms. At last echocardiogram, the proximal transverse arch was 97% (IQR, 84% to 103%) of the diameter of the ascending aorta (z-score, 0.8 (IQR, 0.3 to 1.3]), ejection fraction was 70% (IQR, 60% to 76%), and only 2 patients had significant left ventricular hypertrophy. CONCLUSIONS Arch augmentation via median sternotomy is a safe and effective procedure that can be accomplished with low morbidity and mortality. The reconstructed arch retains excellent growth potential resulting in a very favorable physiologic outcome.

Abstract
Background: In coarctation of aorta associated with proximal arch hypoplasia, extended end-to-end anastomosis through a thoracotomy would result in a residual gradient between the origins of the innominate and the left common carotid arteries. To eliminate this, we modified the surgical technique. Patients and Methods: Between March 2012 and May 2017, 50 patients (14 neonates) underwent repair of coarctation of aorta through a thoracotomy. The age ranged from 6 days to 2 years (median 2 months) and the weight from 1.8 to 8.0 kg (median 4.3 kg). A total of 15 patients (Group A) underwent repair by the extended end-to-end anastomosis. Among them, two patients developed early restenosis at the proximal arch requiring surgical reintervention. Hence, in the second half of the study, 35 patients (Group B) who were identified to have significant hypoplasia of the proximal arch underwent a modified end-to-side anastomosis of the descending aorta to the proximal arch incorporating the distal ascending aorta in the anastomosis and leaving the left subclavian artery end of the isthmus as an end-on vessel. Results: One neonate in Group B died due to a cause not related to the repair. All the other patients in Group B are doing well without a residual gradient during a median follow-up of 23 months. There were no airway issues related to extensive mobilization of the aorta. Conclusion: End-to-side anastomosis of the descending aorta to the proximal arch and side of the ascending aorta is possible through a thoracotomy and can be achieved with good outcome in neonates and infants.

Bovine arch anatomy influences recoarctation rates in the era of the extended end-to-end anastomosis. J Thorac Cardiovasc Surg 2017; 155:1178-1183.

Abstract
OBJECTIVES Arch branching has never been shown to influence recoarctation after extended end-to-end anastomosis via thoracotomy, yet in each study bovine arch identification is grossly underreported. This study aims to (1) assess chart review reliability in bovine arch identification; (2) determine recoarctation risk with a bovine arch; and (3) explore an anatomic explanation for recurrent arch obstruction based on arch anatomy. PATIENTS A total of 49 consecutive patients underwent thoracotomy with extended end-to-end aortic coarctation repair at a single institution (2007-2012). METHODS Echocardiograms from these patients were reviewed for arch anatomy and compared with the echocardiographic reports. Recurrent arch obstruction was defined as an echocardiographic gradient across the repair of 20 mm Hg or greater. For cases with angiographic images (n = 17), a scaled clamping distance between the left subclavian artery and the maximal proximal clamp location on orthogonal projections was then calculated across arch anatomies. RESULTS Chart review identified 6.1% (3/49) of patients with a bovine arch compared with 28.6% (14/49) on targeted image review. A total of 28.6% (4/14) of patients with a bovine arch had a follow-up gradient of 20 mm Hg or greater. Only 5.7% (2/35) of patients with normal arch branching had a follow-up gradient of 20 mm Hg or greater. The mean clamping index was significantly diminished in patients with bovine arch anatomy. CONCLUSIONS Arch anatomy often goes undocumented on preoperative imaging, yet children undergoing extended end-to-end repair with bovine arch anatomy are at a significantly increased risk of recoarctation. This may be due to a reduced clampable distance to facilitate repair. These results should be considered in the preoperative assessment, parental counseling, and surgical approach for children with discrete aortic coarctation.

Coarctation Index Predicts Recurrent Aortic Arch Obstruction Following Surgical Repair of Coarctation of the Aorta in Infants. Pediatr Cardiol 2017; 38:1241-1246. [PMID: 28608147 DOI: 10.1007/s00246-017-1651-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2017] [Accepted: 06/02/2017] [Indexed: 10/19/2022]
Abstract
Recurrent aortic arch obstruction (RAAO) remains a major cause of morbidity following surgical neonatal repair of coarctation of the aorta (CoA). Elucidating predictors of RAAO can identify high-risk patients and guide postoperative management. The Coarctation index (CoA-I), defined as the ratio of the diameter of the narrowest aortic arch segment to the diameter of the descending aorta, has been used to help diagnose RAAO in neonates following the Norwood Procedure. We sought to assess the predictive value of the CoA-I on RAAO after CoA repair in infants with biventricular circulation. Clinical, surgical, and echocardiographic data of infants with biventricular circulation following neonatal CoA repair between 2010 and 2014 were evaluated. RAAO was defined using a composite quantitative outcome variable: a blood pressure gradient >20, a peak aortic arch velocity >3.5 m/s by echocardiogram, or a catheter-measured peak-to-peak gradient >20 within 2 years of surgery. Univariate and multivariate logistic regression analyses were used. Of the 68 subjects included in the analysis, 15 (22%) met criteria for RAAO. In the multivariate model, only CoA-I (OR 35.89, 95% CI 6.08-211.7, p < 0.0001) and use of patch material (OR 9.26, 95% CI 1.57-54.66, p = 0.014) were associated with increased risk of RAAO. The odds of developing RAAO was higher in patients with a CoA-I less than 0.7 (OR 33.8, 95% CI 5.7-199.5, p < 0.001). Postoperative CoA-I may be used to predict RAAO in patients with biventricular circulation after repair of CoA. Patients with a CoA-I less than 0.7 or patch aortoplasty warrant close follow-up.

Abstract
The premature neonate with congenital heart disease (CHD) represents a challenging population for clinicians and researchers. The interaction between prematurity and CHD is poorly understood; epidemiologic study suggests that premature newborns are more likely to have CHD and that fetuses with CHD are more likely to be born premature. Understanding the key physiologic features of this special patient population is paramount. Clinicians have debated optimal timing for referral for cardiac surgery, and management in the postoperative period has rapidly advanced. This article summarizes the key concepts and literature in the care of the premature neonate with CHD.

Immediate Outcomes of Covered Stent Placement for Treatment or Prevention of Aortic Wall Injury Associated With Coarctation of the Aorta (COAST II). JACC Cardiovasc Interv 2016; 9:484-93. [PMID: 26896890 DOI: 10.1016/j.jcin.2015.11.038] [Citation(s) in RCA: 70] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2015] [Revised: 11/04/2015] [Accepted: 11/19/2015] [Indexed: 01/16/2023]
Abstract
OBJECTIVES This study aimed to describe the safety and short-term efficacy of the Covered Cheatham-Platinum stent (CCPS) in treating or preventing aortic wall injury (AWI) in patients with coarctation of the aorta (CoA). BACKGROUND The COAST II trial (Covered Cheatham-Platinum Stents for Prevention or Treatment of Aortic Wall Injury Associated with Coarctation of the Aorta Trial) is a multicenter, single-arm trial using the CCPS for the treatment and/or prevention of AWI in patients with CoA and pre-existing AWI or increased risk of AWI. METHODS Patients were enrolled if they had a history of CoA with pre-existing AWI (Treatment group) or with increased risk of AWI (Prevention group). Pre/post-implant hemodynamics and angiography were reported. A core laboratory performed standardized review of all angiograms. One-month follow-up was reported. RESULTS A total of 158 patients (male = 65%; median age 19 years) underwent placement of CCPS. Eighty-three patients had pre-existing AWI. The average ascending-to-descending aorta systolic gradient improved from 27 ± 20 mm Hg to 4 ± 6 mm Hg. Complete coverage of pre-existing AWI was achieved in 66 of 71 patients (93%) with AWI who received a single CCPS. Ultimately, complete coverage of AWI was achieved in 76 of 83 patients (92%); 7 patients had minor endoleaks that did not require repeat intervention. Four patients experienced important access site vascular injury. There were no acute AWI, repeat interventions, or deaths. CONCLUSIONS The CCPS can effectively treat and potentially prevent AWI associated with CoA. Access site arterial injury is the most common important complication. Longer-term follow-up is necessary to define mid- and late-term outcomes.

Abstract
BACKGROUND Although surgical results for repair of coarctation of the aorta (CoA) have steadily improved, management of this condition remains controversial. The purposes of this study were to analyze the long-term outcomes of patients undergoing CoA repair through left thoracotomy and to define risk factors for reintervention. METHODS All patients who were less than 18 years old and who underwent initial repair of CoA through left thoracotomy from 1995 to 2013 at Texas Children's Hospital (Houston, TX) were included. Patients were classified into 3 groups: 143 (42%) neonates (0 to 30 days old), 122 (36%) infants (31 days to 1 year old), and 78 (23%) older children (1 to 18 years old). Univariate and multivariate analyses were performed. RESULTS A total of 343 patients (129 [38%] girls) with median age of 53 days (interquartile range [IQR],12 days to 9 months) and weight of 4.1 kg (IQR, 3.1 to 8.0) underwent repair with extended end-to-end anastomosis (291 patients [85%]), end-to-end anastomosis (44 patients [13%]), interposition graft (2 patients [0.6%]), or subclavian flap (6 patients [2%]). Concomitant diagnoses included genetic abnormalities (48 patients [14%]), isolated ventricular septal defects (58 patients [17%]), small left-sided structures (53 patients,16%), or other complex congenital heart disease (18 patients [5%]). Perioperative mortality was 1% (n = 4, all neonates). At a median follow-up of 6 years (7 days to 19 years), only 14 (4%) patients required reintervention (10 catheter-based procedures, 6 surgical repairs). A postoperative peak velocity of 2.5 m/s or greater was an independent risk factor for reintervention (odds ratio [OR], 4.0; 95% confidence interval [CI], 1.4 to 11.6). Within the cohort, 95 (33%) patients were hypertensive or remained on cardiac medications a median of 12 years (6 months to 19 years) after the surgical procedure. Development of perioperative hypertension was associated with higher risk of chronic hypertension or cardiac medication dependency (OR, 1.9; 95% CI, 1.1 to 3.3). CONCLUSIONS CoA repair through left thoracotomy is associated with low rates of morbidity, mortality, and reintervention. Aortic arch obstruction should be completely relieved at the time of surgical intervention to minimize the risk of long-term recoarctation.

Abstract
Objective: We have utilized subclavian flap angioplasty (SFA) frequently in infants with coarctation particularly in patients with arch hypoplasia which is quite frequent. We have followed these patients with serial echocardiography and have analyzed our results in this study to determine recoartation rates, recurrent hypertension and left arm development. Methods: Thirty eight infants less than 3 months age (22 boys and 16 girls, mean age was 28±22.6 days) operated at Dokuz Eylul University Hospital between August 2007 - December 2013. Twelve (32%) patients with pulmonary banding due to accompanying VSD or AVSD were included to the study, those infants with complex pathologies such as transposition of great arteries or single ventricle, while the patients less than 1000 gram in weight were excluded. Results: The mean follow-up time was 21 months (1-76 months). Twelve (32%) patients had aortic arch hypoplasia proximal to the left subclavian artery. Operative mortality was found 7.7% for isolated coarctation, 16% for coarctation repair with pulmonary banding. In 5 patients, a residual gradient was detected and re intervention was required in 7.8% patients with balloon angioplasty. Conclusion: Subclavian flap angioplasty is a safe repair technique in small infants and neonates. High gradients and intervention more likely depends on the anatomy of the aortic arch rather than the subclavian flap angioplasty technique.

Abstract
BACKGROUND The Coarctation of the Aorta Stent Trial (COAST) was designed to assess the safety and efficacy of the Cheatham Platinum stent when used in children and adults with native or recurrent coarctation. Acute outcomes have been reported. We report here follow-up to 2 years. METHODS AND RESULTS A total of 105 patients underwent attempted implantation, with 104 successes. There were no procedural deaths, serious adverse events, or surgical intervention. All patients experienced immediate reduction in upper- to lower-extremity blood pressure difference with sustained improvement to 2 years. Rates of hypertension and medication use decreased from baseline to 12 months and remained largely unchanged at 2 years. Six aortic aneurysms have been identified: 5 were successfully treated with covered stent placement, and 1 resolved without intervention. Stent fractures were noted in 2 patients at 1 year and 11 patients at 2 years, with evidence of fracture progression. To date, only larger stent diameter was associated with stent fracture. Twelve additional fractures have occurred after 2 years. No fracture has resulted in loss of stent integrity, stent embolization, aortic wall injury, or reobstruction. Nine reinterventions occurred in the first 2 years for stent redilation and address of aneurysms, and 10 additional reinterventions occurred after 2 years. CONCLUSIONS The Cheatham Platinum stent is safe and associated with persistent relief of aortic obstruction. Stent fracture and progression of fracture occur but have not resulted in clinically important sequelae. Reintervention is common and related to early and late aortic wall injury and need for re-expansion of small-diameter stents. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov.

Abstract
Coarctoplasty with stenting is often an effective strategy in cases of recoarctation following surgical repair. The potential benefit of coarctoplasty in a patient with Eisenmenger's syndrome is unknown. We describe the case of a 21-year-old male who presented with claudication of lower limbs. He was known to have congenital heart disease, consisting of ventricular septal defect, patent ductus arteriosus (PDA), and coarctation of the aorta. Coarctation repair and PDA ligation had been done at two months of age. At the time of presentation for evaluation of claudication, echocardiography revealed severe coarctation and evidence of Eisenmenger's syndrome. This patient subsequently underwent balloon angioplasty and stenting of coarctation without any increase in cyanosis.

Abstract
INTRODUCTION Infants with low body weight (LBW) following cardiac surgery are a major challenge for the post cardiac surgery care unit. It has been observed that post surgery outcome for LBW infants is worse compared to the outcome of normal body weight infants. A study was conducted to compare post operative course and outcome of infants with body weight of 2.2 kg or less against infants with normal body weight who underwent similar cardiac surgeries. METHODS A retrospective review was performed for all infants below 2.2 kg who underwent cardiac operations at King Abdulaziz Cardiac Center from January 2001 to October 2011. Cases with LBW (Group A) were compared with matching group (Group B) of normal body weight infants who had similar cardiac surgeries and matching surgical risk category. The demographic, ICU parameters, complications, and short-term outcome of both groups were analyzed. RESULTS Two groups were formed, with 37 patients in Group A, and 39 patients in Group B. Except for weight (2.13 ± 0.08 kg in Group A vs 3.17 ± 0.2 kg in Group B), there was no statistical difference in demographic data between both groups. Cardiac procedures included coarctation repair, arterial switch, ventricular septal defect (VSD) repair, tetralogy of Fallot repair, systemic to pulmonary shunt and Norwood procedures. Patients in Group A had statistically significant difference from Group B in terms of bypass time (p = 0.01), duration of inotropes (p = 0.01), duration of mechanical ventilation (p = 0.004), number of re-intubations (p = 0.015), PCICU length of stay (p = 0.007), and hospital mortality: 13.5% in Group A vs 0% in Group B (p value 0.02). CONCLUSION Patients with LBW (<2.2 kg) underwent cardiac surgery with overall satisfactory results, but with increased risk of ICU morbidity and mortality.

Factors associated with recoarctation after surgical repair of coarctation of the aorta by way of thoracotomy in young infants. Pediatr Cardiol 2014; 35:164-70.

Abstract
Echocardiography is the mainstay of preoperative arch imaging in infants with coarctation of the aorta. In simple coarctation, repair by way of sternotomy or thoracotomy is often determined by echocardiographic transverse arch measurements. The degree of arch hypoplasia that is prohibitive to repair by way of thoracotomy is unknown. Clinical predictors of recoarctation are also unknown. Demographic, echocardiographic (transverse arch and aortic measurements), operative, and postoperative data of infants <90 days old with simple coarctation repaired by way of thoracotomy between February 2005 and November 2011 were evaluated. Recoarctation was defined as surgical or catheter reintervention after hospital discharge. Eighty-four infants underwent coarctation repair at median age of 12 (range 1-85) days with median follow-up of 12.3 (range 0.5-71.9) months. The seven (8 %) infants with recoarctation underwent balloon angioplasty. In multivariable analysis, only greater postoperative Doppler peak velocity [1.13, confidence interval (CI) 1.04-1.23] and greater sinotubular junction z-score (hazard ratio 4.19, CI 1.47-11.95) independently predicted coarctation. Doppler peak velocity >2.12 m/s had sensitivity of 63 % and specificity of 83 % of predicting recoarctation, and ST junction z-score >-0.93 had sensitivity of 100 % and specificity of 58 %. No transverse arch dimensions were independently associated with recoarctation. Infants with transverse arch z-score as low as -2.8 underwent successful repair by way of thoracotomy. No clinical predictors were significant.

Abstract
BACKGROUND Despite repair, a significant proportion of patients with coarctation of the aorta (CoA) present with late hypertension. Increased gene expression of aortic wall collagen and vascular smooth muscle cell markers occurs in the presence of hypertension. Before repair, a patent ductus arteriosus (PDA) limits hypertension proximal to the coarctation. We hypothesize that preoperative collagen and vascular smooth muscle expression from the aortic arch in children is variable, depending on the presence or absence of a PDA. METHODS We analyzed the expression patterns of collagen and vascular smooth muscle cell markers in 25 children with CoA using a quantitative polymerase chain reaction. Aortic arch tissue proximal to the CoA was normalized to descending aortic tissue distal to the coarctation. Collagen-I, transforming growth factor-β, elastin, and calponin were analyzed. RESULTS At repair, 19 patients were aged younger than 3 months (14 with a PDA, 5 with a ligamentum arteriosum), and the remaining 6 were older than 1 year. There was no difference in age or weight between infants with or without a PDA. Infants without a PDA had the greatest difference in collagen-I expression compared with infants with a PDA (7.0 ± 1.6-fold vs 0.8 ± 1.1-fold, p = 0.01). Expression of transforming growth factor-β (4.3 ± 1.4 vs 2.6 ± 2.3, p = 0.01) and calponin (3.7 ± 0.7 vs 0.6 ± 1.1, p = 0.05) was lower from infants with vs without a PDA. CONCLUSIONS Our findings provide evidence of preoperative changes in the aortic arch before repair, particularly in the absence of a PDA.

Ann Thorac Surg 2013; 96:645-50.

Abstract
BACKGROUND Providing unobstructed systemic blood flow is one goal of stage I palliation for hypoplastic left heart syndrome. Although clinically significant obstruction is defined when the arch gradient exceeds 15 mm Hg, any positive gradient constitutes obstruction, which may impair ventricular function. We sought to identify risk factors before stage I palliation that result in a positive neoaortic arch gradient before bidirectional Glenn. METHODS Reviewed were 51 neonates who underwent stage I palliation and subsequent bidirectional cavopulmonary anastomosis procedures for hypoplastic left heart syndrome. Echocardiograms before stage I palliation were reviewed for aortic dimensions. Cardiac catheterization before bidirectional cavopulmonary anastomosis determined the aortic arch gradient and degree of right ventricular dysfunction. RESULTS Of the 51 patients, 24 (47%) had a negative or absent arch gradient. Patients with a positive gradient had a median gradient of 5 mm Hg (range, 1 to 60 mm Hg). The diameter of the ascending aorta and proximal transverse arch indexed to the descending thoracic aorta (0.5 ± 0.2 vs 0.7 ± 0.4 and 0.4 ± 0.2 vs 0.6 ± 0.2 mm, p = 0.02 and p = 0.01) and lower birth weight (3.1 ± 0.5 vs 3.4 ± 0.4 kg, p = 0.03) were risk factors of a positive neoaortic arch gradient. Further, the degree of arch obstruction was inversely related to the degree of right ventricular function (odds ratio, 1.08; p < 0.01). CONCLUSIONS Lower birth weight and a smaller aortic diameter confer a higher risk of developing a positive neoaortic arch gradient, resulting in reduced right ventricular function.

Abstract
Prenatal diagnosis of coarctation may improve survival, but little is known regarding its association with severity of left heart hypoplasia and surgical outcome. This study compared echocardiographic measurements of left heart structures, surgical strategies, and postoperative outcomes between neonates with a prenatal diagnosis of coarctation and those with a postnatal diagnosis. All the neonates who underwent coarctation repair during 2006-2010 were reviewed. The neonates with complex congenital heart disease or an unrestrictive ventricular septal defect requiring cardiopulmonary bypass (CPB) for closure were excluded from the study. Based on the time of diagnosis, the subjects were divided into the following three groups: group 1 (prenatal diagnosis), group 2 (diagnosis at 0-7 days), and group 3 (diagnosis at 8-28 days). The study population consisted of 46 neonates: 14 in group 1, 14 in group 2, and 18 in group 3. Compared with group 3, group 1 had a smaller left ventricular volume index, lower mitral and aortic valve diameter z-scores, and lower transverse arch z-scores. Compared with group 2, group 1 had smaller aortic valve z-scores but otherwise had similar measurements. At repair, 64 % of the neonates in group 1 required CPB versus 29 % in group 2 (p = 0.12) and 22 % in group 3 (p = 0.03). All the neonates underwent biventricular repair, with no surgical mortality. Group 1 had a hospital stay of 13.4 ± 10.8 versus 7.5 ± 4.2 days in group 2 (p = 0.06) and 7.3 ± 4.5 days in group 3 (p = 0.03). The neonates with prenatally diagnosed coarctation had smaller left heart structures than the neonates with coarctation diagnosed after the first week of age, were more likely to require extensive arch reconstruction under CPB, and had longer hospital stays.

Abstract
OBJECTIVES A variety of surgical approaches and techniques are used for isolated coarctation repair. We have retrospectively reviewed our results of isolated repair of coarctation over the last 20 years, to establish whether the approach affects clinical outcome and the need for re-intervention. METHODS Two hundred and eighty-eight patients who underwent isolated repair for coarctation of the aorta at Birmingham Children's Hospital between 1991 and 2010 were enrolled in this study. Chart review and the Departmental database were used to determine demographics, operative details and complications. RESULTS The majority of patients (n = 237, 82%) underwent surgical repair via thoracotomy techniques, whereas median sternotomy was used in patients where there was associated arch hypoplasia (n = 51, 18%). For all 288 patients, median age at operation was 24 days (range 0-14 years). Between 1991 and 2000, ten patients (6%) underwent repair through midline sternotomy, increasing to 41 patients (36%) between 2001 and 2010. Overall early mortality was 1% and late mortality was 3%. There was a statistically higher re-intervention rate (16%) in the decade 1991-2000, compared to 5% in the period 2001-10 (P = 0.02). In patients with hypoplastic arch, the midline approach has a lower re-intervention rate than thoracotomy (P < 0.001). CONCLUSIONS In our institution, there has been a trend in recent years towards increased use of median sternotomy to repair the aortic arch, which has been associated with a reduced rate of re-intervention. The midline sternotomy approach for coarctation with arch hypoplasia significantly reduces the risk of re-coarctation.

Abstract
Aortic coarctation is a common congenital cardiac defect, which can be diagnosed over a wide range of ages and with varying degrees of severity. We present two cases of patients diagnosed with aortic coarctation in adulthood. Both patients were treated by an endovascular approach. These cases demonstrate the variety of indications in which percutaneous treatment is an excellent alternative for surgical treatment in adult native coarctation patients.

Abstract
OBJECTIVE The goal of aortic coarctation repair is laminar aortic blood flow resulting in a negative or absent arm:leg blood pressure (BP) gradient. Despite satisfactory relief of coarctation, associated arch hypoplasia can result in residual obstruction and postoperative upper body hypertension. INTERVENTION We devised a surgical strategy to create a tension-free anastomosis with a diameter as large as both the adjacent proximal and distal aorta using a radically extended end-to-end anastomosis via sternotomy and/or thoracotomy. Sternotomy is chosen when there is significant transverse arch hypoplasia defined as a distal transverse arch ≤ diameter of the left carotid artery, presence of a common brachiocephalic trunk, or coexisting intracardiac lesion requiring repair. Thoracotomy is used in all other cases. RESULTS From 2000 to 2008, 95 consecutive patients were repaired using this approach, 35 with sternotomy and 60 with thoracotomy. At a mean follow-up of 50 ± 23 months, mean systolic BP was 94 ± 10 mm Hg, and 84% of patients had no residual arm:leg BP gradient. Mean arm:leg BP gradient was not statistically different between groups (-8.5 ± 15 sternotomy and -7.0 ± 10 mm Hg thoracotomy, P= .7). With Doppler echocardiography, 96% of patients demonstrated normal early diastolic reversal of blood flow in the descending thoracic aorta. CONCLUSIONS For aortic coarctation repair in infancy, a strategy designed to directly address aortic arch hypoplasia results in excellent intermediate-term results with normal BP, physiologic arm:leg BP relationship, and near normal descending aortic blood flow velocities by Doppler.
