Stent Implantation and Balloon Angioplasty for Native and Recurrent Coarctation of the Aorta.

Evidence on the effectiveness and comparative effectiveness of stent implantation and balloon angioplasty for native coarctation of the aorta (CoA) and recurrent CoA separately is lacking. The present meta-analysis was performed to assess the efficacy and safety of stent implantation and balloon angioplasty in native (NaCo) and recurrent (ReCo) CoA.A systematic computerized literature search was conducted to retrieve all relevant studies of stent implantation and balloon angioplasty for CoA. Both single-arm and comparative studies were included. Data on NaCo and ReCo were pooled separately.A post-procedure gradient of ≤ 20 mmHg was achieved in 97% and 92% of patients undergoing stent implantation and balloon angioplasty for NaCo, and in 98% and 90% for ReCo, respectively. A post-procedure gradient of ≤ 10 mmHg was achieved in 97% and 83% of patients undergoing stent implantation and balloon angioplasty for NaCo, and in 86% and 78% for ReCo, respectively. Comparative results confirmed that stent implantation provided a significantly higher success rate compared with balloon angioplasty (odds ratio [OR] = 2.09; 95% confidence interval [CI] = 1.13-3.86; P = 0.019) in treating NaCo. Incidences of all-cause complications, mortality, reintervention, and aneurysm formation were similar between the groups. Patients undergoing stent implantation had a significantly lower incidence of dissection (OR = 0.15; 95% CI = 0.02-0.92; P = 0.040).Current evidence indicates that stent implantation might have superior efficacy compared with balloon angioplasty for the treatment of NaCo with higher success rates and similar complication rates. However, whether this superior effect is also present in ReCo patients needs further evaluation.

Intermediate and Long Term Follow Up of Balloon Angioplasty for Native Coarctation of the Aorta in Neonates and Infants

Background: Balloon angioplasty (BA) became an alternative procedure for the management of CoA, which initially performed at 1983 (5). The effectiveness of BA for the management of native CoA remains controversial in neonates (less than one month) and infants under the first year of life, in spite of its acceptable morbidity and the reduced complication rates. This controversy was due to higher re-stenosis rate and the increased risk of aneurysm formation present with CHF, which might also increase the surgical risk. Objective: To study the intermediate and the long-standing effects of BA for native CoA in neonates and infants and to determine any predictive factors for the outcome. Patients and Method: Included in the study were all patient 12 days to 11 months referred for possible balloon dilation to our Ibn-Albaitar teaching hospital department of congenital cardiac intervention with evidence of discrete coarctation of aorta. The hemodynamic data, angiogram and clinical records of 63 patients were examined with follow up data from 2 to 138 months (median 72 months). Results: Immediate success with balloon angioplasty was achieved in 35 Patients of 63 patients. 33 patients (52 %) with intermediate follow up data ( rang 12 to 138 months ) available are asymptomatic and normotensive with insignificant arm to leg blood pressure gradient (is lellss than 20 mmHg). 28 patients (44.4%) with primary successful result showed increase in gradient at 2 to 86 months after angioplasty requiring re-intervention in 28 Patients. Follow up after 84 months was available in 55 patients, 92% of whom are normotensive and have not required additional intervention. No additional intervention was needed in our patients > 7 years old. 17 of 29 surviving neonates who initially had a successful dilatation required re-angioplasty or operation after angioplasty. Transverse arch hypoplasia showed negligible effect on blood pressure gradient; whereas isthmus hypoplasia is linked with re-intervention in 14 % of patients. A small aneurysm was noted in 1 (1.5%) patients of 63 Patients. Conclusion: BA of native CoA is effective in neonates, infants under the first year of life, and also in the older children, the aneurysm formation is rare, and however life time follow up is reasonable.

The immediate and late results for balloon angioplasty of native coarctation of aorta in pediatrics age group

Background: percutaneous balloon dilation of corotation of aorta is a less invasive and alternative to surgical repair for patients with discrete coaction of aorta and although the used of balloon angioplasty in patients with recurrent postoperative coarctation gained a wide consensus, the use this technique for native coarctation is still controversial in children less one years. 
 Objective: to evaluate the immediate and late result of balloon dilation of native coarctation of aorta in infant and children.
 Type of the study: A prospective study. 
 Subjects & Methods: The study was done on forty-five patients who were referred for cardiac catheterization and balloon angioplasty of native coarctation of the aorta at Ibn-AL-Bitar center for cardiac surgery between January 2015 to May 2016.Left heart catheterization was performed with evaluation of the morphology and pressure gradient across the stenotic segment of aorta. Follow up evaluations were done between 1 week and 18 months after discharge (mean 6 months) with transthoracic echocardiography. 
 Results: The age of patients range from 1month to 4 years (median age at time of procedure was12.3month). Associated lesions in 11 patients (24.4%). Immediate results were reduction in gradient from 42.5± 17.3 to 10.3± 8.2 mm Hg in forty-two patients (93.3%). Late result during follow up period, 29 patients (69%) had maintain gradient less than 20mmHg. Complications were reported in 6 patients (13.3%). there was one procedure related death (2.2%). 
 Conclusions: Balloon angioplasty for treatment of native coarctation of the aorta is effective with sustained benefit on long-term follow-up in infants and children >6 months. Transverse arch hypoplasia and children <6 months old has major effect on late outcome of recurrent coarctation of aorta.

Balloon Angioplasty for Native Aortic Coarctation in 3- to 12-Month-Old Infants.

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

Comparison Between Balloon Angioplasty and Surgical treatment for Native Coarctation of the Aorta in Infants

Coarctation of the aorta (CoA) is a discrete stenosis of the proximal thoracic aorta. The common clinical pattern is congestive heart failure in infancy. Treatment methods include balloon angioplasty (BA) and surgical repair in this age group. Percutaneous balloon angioplasty is a less invasive method for the repair of discrete coarctation but remains controversial as a primary treatment strategy for a native coarctation.
 This study aimed to compare the effectiveness and outcome of balloon angioplasty and surgical repair in infants with coarctation of the aorta younger than one year old.
 Methods. Between January 2011 and December 2017, 59 patients with native aortic coarctation were treated in National Amosov Institute of Cardiovascular Surgery. This retrospective study evaluated the results of the two methods in patients younger than one year old with the diagnosis of coarctation of the aorta. Group 1 included 18 patients who accepted balloon dilatation for discrete coarctation. Group 2 included 41 patients who underwent surgical resection with end-to-end anastomosis. Patients with complex cardiac anomalies were not included in this study.
 Results. Immediate results revealed no significant difference in the effectiveness of the two methods (p value =0.06). While the rate of recurrent coarctation was significantly lower in the surgery group [1 (2,4%) vs. 13 (72,2%), p value =0.0017]. The mean hospital stay was 6.4±3.6 days in the balloon angioplasty group and 21.5±8.7 days in the surgery group, which constitutes a significant statistical difference (p value <0.05). Aneurysm formation was not encountered.
 Conclusion. Both surgical repair and balloon angioplasty for native coarctation of the aorta in infants were effective and beneficial. These data suggest that balloon angioplasty can be acceptable alternative to surgical treatment but due to the high level of recoarctation this method may be considered in critically ill infants with congestive heart failure as a primary palliative procedure. The limitations of this study were its retrospective, nonrandomized nature, and smaller case numbers.

A comparison of balloon angioplasty of native coarctation versus surgical repair for short segment coarctation associated with ventricular septal defect-a single-center retrospective review of 92 cases.

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

Long-Term Results of Balloon Angioplasty for Native Coarctation of the Aorta in the Surgical Specialty Teaching Hospital/Cardiac Center/Hawler

Background: Coarctation of aorta is a common congenital cardiac malformation; controversy has surrounded the use of balloon angioplasty for native coarctation of aorta as the primary treatment for patients with various ages with coarctation. Aim: This study aimed to assess the long term outcome of balloon angioplasty especially concerning aneurysm formation. Patients and Methods: A case series (case follow-up) study was carried out on a total of 50 patients (31 male and 19 female) with native coarctation of aorta aged 1 - 21 years of age who were treated with balloon angioplasty for more than 1 year at the time of follow up evaluation in surgical specialty hospital/cardiac center in Erbil Iraq. They were recalled and subjected to detail clinical examination, body weight, height, blood pressure measurements. Radiographic, Echo Doppler data, CT angiography were obtained. CT angiography was done for 34 patients. Full echocardiographic evaluation was done in follow up visits. Results: There was a significant reduction in the peak instantaneous pressure gradient across the coarctated area by Doppler echocardiogram gradient before balloon angioplasty and at the follow up visit from 56.92 ± 14.6 mmHg to 30.68 ± 16.89, P = 0.00. Six cases of total 50 patients had evidence of diastolic runoff pattern by Doppler Echcardiogram. While the only 6 of total 34 cases had the report of CT angiography that documented aneurysm formation (12%). Conclusions: Balloon angioplasty of native aortic coarctation can be performed safely and effectively with good immediate outcome. Furthermore, it offers satisfactory long-term results with low incidence of persisting restenosis, hypertension and aneurysm formation.

Balloon angioplasty for native coarctation in children: one year follow-up results

Balloon angioplasty is an alternative to surgical repair for coarctation of the aorta in children. However, its role in the treatment of neonates and infants younger than 3 months old remains controversial. The purpose of this study was to evaluate the efficacy and safety of balloon angioplasty for native coarctation by comparing children in different age groups. This is a retrospective clinical study including 37 children treated with balloon angioplasty for native coarctation from January 2006 to December 2012. A total of 37 patients consisting of 26 boys and 11 girls underwent the procedure, with median age 10 months (range from 7 days to 6 years) and the mean body weight was 6.3 (2.5-17.0) kg. The indication of the procedure includes discrete native coarctation without aortic arch hypoplasia and a peak-to-peak systolic pressure gradient > 20 mmHg (1 mmHg = 0.133 kPa) across aortic coarctation. During one year follow-up, the approach artery injury, recoarctation and aneurysm formation were particularly assessed. We classified these patients into two groups according to their age. Group A consisted of 25 patients younger than 3 months and Group B of 12 patients older than 3 months. There was no significant difference between the two groups in systolic pressure gradient before balloon angioplasty (P > 0.05). The mean peak systolic gradient decreased from (38 ± 18) mmHg to (12 ± 11) mmHg immediately after angioplasty in group A and from (47 ± 18) to (17 ± 12) mmHg in group B (P = 0.000 for both). Meanwhile, the mean diameter of the coarctation segment increased from (1.8 ± 0.7) to (3.7 ± 1.1) mm after angioplasty in group A and from (2.6 ± 1.5) to (5.5 ± 1.8) mm in group B (both P = 0). The initial successful balloon angioplasty (immediate postangioplasty peak pressure gradient < 20 mmHg) was achieved in all the 37 patients; 32 patients (86.5%) have been followed up for one year. Approach arterial complications occurred in 3 patients (9.4%), all of whom were in Group A (P = 0.537). Two patients had decreased femoral artery pulse and one required surgical repair for a postoperative pseudoaneurysm at left carotid artery. At follow-up, 8 patients (25.0%) developed recoarctation, with 6 cases in Group A and 2 in Group B. There was no significant difference between groups A and B in the recoarctation rate (P = 1.000). Among them, 7 patients underwent repeat balloon angioplasty, and all showed successful relief of coarctation, and one patient required surgical repair. Two patients (2/37, 5.4%) had small aneurysms of the descending aorta immediately after balloon angioplasty, with one patient in each group (12/25 vs.1/12, P = 0.755).Late aneurysm development has not been observed in the 17 patients who have had a follow-up CTA or MRA study. Balloon angioplasty of discrete native coarctation is effective and safe in children both younger and older than 3 months with similar incidence of approach arterial complication, recoarctation and aneurysm formation.

Does thez-Score Value of the Abdominal Aorta Predict Recoarctation in an Infant?

We evaluated left ventricular dimensions and aortic arch z-scores in infants who underwent balloon angioplasty (BAP) or surgery for coarctation of aorta (CoA). We searched for risk factors predicting recoarctation. Between 2007-2011, 27 male and 17 female infants (mean age 2.93 ± 4.78 months, range 2 days-24 months) with CoA were evaluated. Left ventricular dimensions, systolic functions, mitral and aortic annuli, transverse aortic arch, isthmus, coarctation site, and diaphragmatic aorta measurements were done and z-scores were determined before intervention. Six patients underwent primary operation, 38 patients had BAP (86.4%). Associated cardiac pathologies in operated patients were double outlet right ventricle (n = 2), atrioventricular septal defect (n = 1), Ebstein's anomaly (n = 1), arch hypoplasia (n = 2). Twelve patients (27.2%) had simple coarctation. Ventricular septal defect was the most frequent associated cardiac pathology (n = 20, 45.4%). The patients were followed for 10.22 ± 8.21 months. Among 33 primary successful BAP's, 14 had recoarctation (42%). Eleven patients were primarily operated (including 5 with unsuccessful BAP), two had recoarctation (18%). Abdominal and transverse aorta values and z-scores were significantly lower in the recoarctation group (7.15 ± 2.12 mm and 6.07 ± 1.86 mm respectively in the "no-recoarctation group"; vs. 5.53 ± 0.75 mm and 4.94 ± 1.53 mm in the "recoarctation group" P <.05). Abdominal aorta z-score of 0.42 was 88.9% sensitive and 53.8% specific to predict recoarctation (area under ROC curve: 0.618-0.902, P <.05). Although BAP for native coarctation is still a controversial treatment option due to frequent restenosis rates, abdominal aorta z-score of 0.42 could correctly eliminate recoarctation in 89% of these cases. This cutoff value might help us choose patients for primary BAP and decrease the recoarctation rate after BAP.

Improvement of Left Ventricular Mass Following Balloon Angioplasty of Native Coarctation of the Aorta: Midterm follow-up in Cairo University, Children's Hospital

Objectives: We evaluated mid-term results of balloon angioplasty (BAP) of native coarctation of the aorta (CoA) in children. There is paucity of data on left ventricular hypertrophy (LVH) and left ventricular mass (LVM) post balloon dilatation of native CoA, hence we also assessed LVM regression. Study Design: Thirteen children were included (11 boys, 2 girls) with median age at intervention of 16 months (4 -96 months) and all underwent BAP for native CoA. Pati ents were followed-up by transthoracic echocardiography assessment of left ventricular function, LVM, recoarctation, and other complications. Follow -up period ranged from9 � 36 months (mean±SD, 24.38±8.22 months). Results: The mean peak systolic gradient d

Balloon Angioplasty for Native Coarctation of the Aorta in Neonates and Infants With Congestive Heart Failure

Balloon angioplasty (BA) is an alternative to surgical repair for coarctation of the aorta (CoA) in children. However, its role in the treatment of native CoA in neonates and infants remains controversial. The purpose of this study was to report the midterm outcomes of BA for native CoA in neonates and infants with congestive heart failure (CHF). Between July 2000 and March 2007, 18 neonates and infants with native CoA and CHF who underwent BA were enrolled. Patients without recoarctation were designated as group A, while those with recoarctation or CHF were designated as group B. The clinical presentations, laboratory data, and outcomes were compared between groups. There were 10 patients in group A and eight in group B. The mean age was 2.8 +/- 3.1 months (range, 0.7-11 months). Mean body weight was 4.0 +/- 1.9 kg (range, 2.1-8.0kg). CHF improved markedly in all patients immediately after BA, with a reduction in systolic pressure gradient from 36.4 +/- 12.0 to 5.6 +/- 6.0 mmHg (p < 0.001). The recoarctation rate was 44% (8/18). The risk factors for restenosis were post-BA systolic pressure gradient >10 mmHg (p = 0.007) and CoA diameter <3 mm (p = 0.013). The outcomes of BA for native CoA in neonates and infants with CHF remain poor. The incidence of recoarctation is high in neonates and patients whose post-BA systolic pressure gradient is >10 mmHg or whose CoA diameter is <3 mm.

Long‐term outcome after balloon angioplasty of coarctation of the aorta in adolescents and adults: Is aneurysm formation an issue?

The purpose was to evaluate long-term outcome following balloon angioplasty for coarctation in adults. Long-term results of balloon angioplasty for native coarctation in adults remain incomplete, especially concerning the occurrence of aneurysm formation. Long-term follow-up data were collected in consecutive patients retrospectively. Results of balloon angioplasty (29 patients, age 15-71 years, during 1995-2005) for discrete, native coarctation were evaluated, including MRI or CT. Mean follow-up ranged from 2.2 to 13 years (mean 8.5 +/- 3.2). Immediate success was obtained in all patients. Early mortality or complications were not encountered. Peak systolic pressure gradient decreased from 52 +/- 21 to 7.2 +/- 7.6 mm Hg (P < 0.001). Intima tear was detected in eight procedures angiographically, without signs of dissection. Three-month follow-up angiography in these patients showed unchanged (4/8 patients) or diminished abnormalities (4/8 patients). One asymptomatic patient, known with left ventricular dysfunction due to significant aortic valve insufficiency, died suddenly 5 years after balloon angioplasty. Recoarctation occurred in one patient (3%). Late aneurysm formation was excluded by MR in 24/29 and CT in remaining 5/29 patients during follow-up, including those patients in whom intima tear was encountered immediately postangioplasty. In three of seven patients an irregular aortic contour persisted, without indication of progression or aneurysm formation. Hypertension was completely relieved in 67% (14/21 patients) and improved in 33% (7/21 patients). Balloon angioplasty for native coarctation yields low reintervention probability in adult patients. Despite occurrence of angiographically established intimal tearing, aortic dissection and aneurysm formation were not encountered.

Balloon Angioplasty for Native Aortic Coarctation in Different Anatomic Variants

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

Balloon Angioplasty of Native Coarctation and Comparison of Patients Younger and Older Than 3 Months

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

Balloon Angioplasty for Native Coarctation in Children: Immediate and Medium-Term Results

The use of balloon angioplasty to treat native aortic coarctation in pediatric patients is controversial. Our aims were to report our experience with this technique and to compare retrospectively the immediate and medium-term results obtained during 2 distinct time periods. 53 patients who underwent balloon angioplasty for native coarctation were divided into 2 groups: (A) those treated between 1985-1988 (n=26); and (B) those treated between 1993-2003 (n=27). Follow-up data were available for all patients. The immediate result was good (i.e., pressure gradient, <20 mmHg) in 18/26 patients in group A (69.2%) and 22/27 (81.5%) in group B. On follow-up, the recoarctation rate was similar in both groups: 33% in group A and 25.6% in group B. Group A patients with recoarctation were referred for surgery, whereas group B patients underwent a second angioplasty (either balloon or stent). At the end of follow-up, angioplasty had been successful in 62% (16/26) of patients in group A vs 85% (23/27) in group B. The incidence of serious complications was lower in group B (4%) than group A (19.2%), as was the incidence of aneurysm: 4% in group B vs 15% in group A. Balloon angioplasty is an effective alternative to surgery for the treatment of native, localized aortic coarctation. Better selection of suitable patients, use of low-profile catheters, and improved patient care can reduce the incidence of complications. Repeat angioplasty (either balloon or stent) in cases of recoarctation has improved results with this technique.
