Zhao Z, Pan Z, Wu C, Tian J, Qin J, Zhang Y, Jin X. Risk factors for recurrence after surgical repair of coarctation of the aorta in children: a single-center experience based on 51 children. Front Cardiovasc Med 2023; 10:1144755. [PMID: 37324620 PMCID: PMC10267975 DOI: 10.3389/fcvm.2023.1144755] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Accepted: 05/16/2023] [Indexed: 06/17/2023] Open
Abstract
Background Coarctation of the aorta (CoA), is a congenital malformation, often combined with several cardiac abnormalities. At present, the operation effect is satisfactory, but postoperative restenosis is still a matter. Identification of risk factors for restenosis and prompt therapy adjustments may improve patient outcomes. Materials and methods A retrospective clinical study of patients under 12 who had CoA repair in 2012-2021, with a randomized cohort population of 475 patients. Results A total of 51 patients (M/F: 30/21) with a mean age of 5.33 (2.00-15.00) months and a median weight of 5.60 (4.20-10.00) kg. The mean follow-up was 8.93 (3.77-19.37) months. Patients were divided into 2 groups: no-restenosis (n-reCoA) (G1, 38 patients) and restenosis (reCoA) (G2, 13 patients). ReCoA was defined as a restenosis requiring interventional or surgery or a pressure gradient >20 mmHg at the repair site as reported by B-ultrasound with the presence of an upper and lower limb blood pressure gradient or growing dysplasia. The overall reCoA incidence was 25% (13/51). In multivariate COX regression, smaller preoperative z-score of the ascending aorta (P = 0.009, HR = 0.68) and transverse aortic arch (P = 0.015, HR = 0.66), arm-leg systolic pressure gradient ≥12.5 mmHg at discharge (P = 0.003, HR = 1.09) were independent risk factors for reCoA. Conclusion The overall outcome of CoA surgery is successful. Smaller preoperative z-score of the ascending aorta and transverse aortic arch, and an arm-leg systolic pressure gradient ≥12.5 mmHg at discharge increase reCoA risk, and closer follow-up for such patients are required especially within 1 postoperative year.

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

Abstract
OBJECTIVE To investigate the correlation between the degree of aortic coarctation and surgical prognosis in infants with simple coarctation of the aorta (CoA) using computed tomography angiography (CTA). METHODS This study was a retrospective study. Twenty-seven infants with simple CoA who underwent surgical correction from January 2020 to June 2022 were enrolled. Aortic diameters were measured at five different levels and normalized to Z scores based on the square root of body surface area. The relevant data were collected and analyzed, and the predictors associated with surgical outcome were determined. RESULTS Patients were divided into the mild CoA group and the severe CoA group according to the severity of coarctation. The mechanical ventilation duration and the length of ICU stay in the mild CoA group were significantly lower than those in the severe CoA group. Multiple linear regression analyses revealed that the degree of aortic coarctation was a significant risk factor for a prolonged postoperative ICU stay. In addition, gestational age and age at operation were risk factors for a prolonged postoperative ICU stay. Correlation analysis showed that the degree of aortic coarctation correlated with the Z scores of the ascending aorta and postcoarctation aorta. CONCLUSION The degree of the CoA is an important predictor of surgical outcomes in infants with simple CoA and was significantly correlated with the ascending aorta and postcoarctation aorta Z scores. Therefore, preoperative CTA should be routinely performed to assess the degree of aortic coarctation and better identify risk factors.

Abstract
BACKGROUND Aortic coarctation is among the most common cardiovascular congenital abnormalities requiring repair after birth. Besides mortality, morbidity remains an important aspect. Accordingly, we reviewed our 20-year experience of aortic coarctation repair by thoracotomy, with emphasis on both short- and long-term outcomes. METHODS From 1995 through 2014, 214 patients underwent coarctation repair via left thoracotomy. Associated arch lesions were distal arch hypoplasia (n = 117) or type A interrupted aortic arch (n = 6). Eighty-four patients had isolated coarctation (group 1), 66 associated ventricular septal defect (group 2), and 64 associated complex cardiac lesions (group 3). Median follow-up was 8.4 years. RESULTS There was one (0.5%) procedure-related death. Nine (4.2%) patients died during index admission. In-hospital mortality was 0.7% in group 1 and 2 and 12.5% in group 3 (P < .001). No patient had paraplegia. Actuarial five-year survival was 97.5% in group 1, 94% group 2 and 66% in group 3. Recurrent coarctation developed in 29 patients, all but four (1.8%) successfully treated by balloon dilatation. Freedom from reintervention (dilatation or surgery) at five years was 86%. At hospital discharge, 28 (13.5%) patients were hypertensive. At follow-up, hypertension was present in 11 (5.3%) patients. CONCLUSIONS Long-term results of aortic coarctation repair by thoracotomy are excellent, with percutaneous angioplasty being the procedure of choice for recurrences. Patient prognosis is dependent on associated cardiac malformations. In this study, the prevalence of late arterial hypertension was lower than previously reported.

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
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: Coarctation of the aorta (CoA) with aortic arch hypoplasia (AAH) is a relatively common congenital heart disease in clinical practice. Nonetheless, the corrective surgical technique for infants and children is a clinical problem that remains controversial. In this study, we sought to evaluate the surgical effects of aortic arch (AA) reconstruction with coarctation resection and aortoplasty with autologous pulmonary artery patch for infants and young children with CoA and AAH. Methods: Between January 2009 and December 2015, a total of 22 infants and young children with CoA and AAH who underwent coarctation resection and aortoplasty with autologous pulmonary artery patch were enrolled in this study. The median age of patients was 4.5 (Q1, Q3: 2.0, 14.0) months and the median body weight was 5.75 (Q1, Q3: 4.10, 9.38) kg. All patients were diagnosed with CoA and AAH, and concomitant cardiac anomalies were corrected in one stage. Perioperative and postoperative data were collected and analyzed using the paired sample t-test. Results: No perioperative deaths occurred. No residual obstruction was detected by echocardiography. The postoperative pressure difference across the repaired segment of CoA was 14.05 ± 4.26 mmHg (1 mmHg = 0.133 kPa), which was smaller than the preoperative pressure difference (48.30 ± 15.73 mmHg; t = −10.119, P < 0.001). The median follow-up time was 29.0 (Q1, Q3: 15.5, 57.3) months. There was no death during the follow-up period, and all patients experienced obvious clinical improvement. Only one child underwent subsequent aortic balloon angioplasty due to restenosis. Computed tomography angiography showed that the AA morphology was smooth, with no aortic aneurysm or angulation deformity. Conclusion: AA reconstruction with coarctation resection and aortoplasty with autologous pulmonary artery patch could effectively correct CoA with AAH, and the rate of reintervention for restenosis is low.

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
Aortic coarctation is one of the most common congenital cardiac pathologies. Repair of native aortic coarctation is nowadays a common and safe procedure. However, late complications, including re-coarctation and aneurysm formation, are not uncommon. The incidence of these complications is dependent on the type of the initial operation. Both endovascular and conventional open repair play important roles in the treatment of late complications after previous coarctation repair. This article will review the incidence of late complications after coarctation repair and will discuss the treatment options for redo coarctation repair in adult patients.

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
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. The purpose of this article is to summarize the roles of CT and MRI in the diagnosis and follow-up of patients with aortic coarctation. CONCLUSION. Aortic coarctation is a common congenital heart disease accounting for approximately 6-8% of congenital heart defects. Despite its deceptively simple anatomic presentation, it is a complex medical problem with several associated anatomic and physiologic abnormalities. CT and MRI may provide very accurate information of the coarctation anatomy and other associated cardiac abnormalities.

Abstract
Aortic coarctation represents a distinct anatomic obstruction as blood moves from the ascending to the descending aorta and can present in a range of ages from infancy to adulthood. While it is often an isolated and discrete narrowing, it can also be seen in the more extreme scenario of severe arch hypoplasia as seen in the hypoplastic left heart syndrome or in conjunction with numerous other congenital heart defects. Since the first description of an anatomic surgical repair over sixty years ago, an evolution of both surgical and transcatheter therapies has occurred allowing clinicians to manage and treat this disease with excellent results and low morbidity and mortality. This review focuses on the current state of both transcatheter and surgical therapies, paying special attention to recent data on long-term follow-up of both approaches. Further, current thoughts will be explored about future therapeutic options that attempt to improve upon historical long-term outcomes.

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. [PMID: 23852462 DOI: 10.1007/s00246-013-0757-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2013] [Accepted: 06/20/2013] [Indexed: 10/26/2022]
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.

Ann Thorac Surg 2012; 94:751-6; discussion 757-8.

Abstract
BACKGROUND Open, hybrid, and endovascular procedures are used for grown-up patients with aortic coarctation and complications after repair, an expanding population. We sought to characterize patients and procedures, assess early and late outcomes, and describe indications to guide treatment of these complex patients. METHODS Between May 1999 and January 2011, 110 patients underwent open (n=40), hybrid (n=11), or endovascular (n=59) repair of coarctation (n=43), recurrent aortic coarctation (n=42), or postrepair aneurysm (n=25). Mean age was 38±14 years. Sixty-eight had previous repairs (median 27 years earlier; range, 1 to 50). Twenty-two had prior cardiovascular operations other than coarctation and 50% had bicuspid valve. Fifty-nine concomitant procedures were performed in 45 patients (40%). Data were from the prospective database, chart review, and Social Security Death Index. RESULTS Technical success was achieved in 100%, with no hospital deaths, no strokes, and no paraplegia. Complications were uncommon and included respiratory failure (n=2, 1.8%), and temporary renal failure (n=2, 1.8%). Twenty-two patients required reinterventions, but half of those were planned. There was no difference in occurrence of unplanned reintervention between approaches (endovascular 12%, hybrid 18%, open 12.5%). Length of stay was 4.8±4.8 days. Transcoarct gradient fell from 37.6±18 mm Hg preoperatively to 7.0±6.9 mm Hg in coarctation patients. Postrepair aneurysm patients had no late ruptures, and maximum diameter shrunk from 5.9±1.3 cm preoperatively to 4.8±1.3 cm. Estimated survival at 1, 5, and 8 years was 95%, 95%, and 90%, respectively. CONCLUSIONS Coarctation, recurrent coarctation, and postrepair aneurysm/pseudoaneurysm in adolescent and adult patients can be safely and effectively managed with open, hybrid, or endovascular techniques. Optimal results are achievable in this complex population of patients with a multimodality approach tailored to surgical indication and anatomy. All survivors of coarctation repair require lifelong surveillance.
