Ahmadi A, Mansourian M, Sabri MR, Ghaderian M, Karimi R, Roustazadeh R. Follow-up outcomes and effectiveness of stent implantation for aortic coarctation: A systematic review and meta-analysis. Curr Probl Cardiol 2024; 49:102513. [PMID: 38556144 DOI: 10.1016/j.cpcardiol.2024.102513] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 03/03/2024] [Accepted: 03/13/2024] [Indexed: 04/02/2024]
Abstract
BACKGROUND The authors aim to investigate the clinical implications of stent use for the management of CoA. METHODS All observational studies on stent implantation for the treatment of aortic coarctation and the relevant RCTs were systematically retrieved. Outcomes included the immediate success rate, pre- and post-stent gradient, survival, minor and major complications, restenosis, post-stent systolic blood pressure, and reintervention rate. The analysis was further stratified by CoA type, stent type, and the mean age of the patients. RESULTS Our meta-analysis incorporated 66 eligible studies involving 3,880 patients. The success rates for stent placement, defined as achieving post-treatment gradients of ≤20 mmHg and 10 mmHg, 0.96 (95% CI: 0.95 - 0.97; I2 = 59.83%) and 0.92 (95% CI: 0.89 - 0.95, I2 = 77.63%) respectively. The complication rates were quite low, with minor and major complication rates of 0.017 (95% CI: 0.013 - 0.021) and 0.007 (95% CI: 0.005 - 0.009), respectively. Unplanned reinterventions were required at a rate of 0.021 (95% CI: 0.015 - 0.026). At a mean follow-up of 2.9 years, 97% of the patients survived and 28% remained on antihypertensive therapy. While immediate effectiveness was consistent across age groups, complications were more prevalent in patients aged <20 years, and long-term efficacy was lower in those aged >20 years. Encouragingly, in neonates and infants, CoA stenting yielded results comparable to those observed in older children. CONCLUSION These findings underscore the overall favorable outcomes of stent placement for aortic coarctation, with considerations for age-related variations in complications and long-term efficacy.

Medium-Term Outcomes of Stent Therapy for Aortic Coarctation in Children Under 30 kg with New Generation Low-Profile Stents: A Follow-Up Study of a Single Centre Experience. Pediatr Cardiol 2024; 45:544-551. [PMID: 38315219 PMCID: PMC10891239 DOI: 10.1007/s00246-023-03402-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Accepted: 12/28/2023] [Indexed: 02/07/2024]
Abstract
We previously reported short-term outcomes for stenting of aortic coarctation (CoA) (native or re-coarctation) with newer generation low-profile stents (Valeo, Formula, and Begraft stents) in children under 30 kg. We present here the medium-term outcomes of this procedure. Retrospective review of patients weighing under 30 kg who had percutaneous stent treatments for coarctation between 2012 and 2021 was performed. Clinical and procedural data were collected; 19 patients were included. The median age at the time of procedure was 5.1 [4.1-6.4] years and median weight 21.0 [17.3-22.3] kg. One patient had a history of re-coarctation. Thirteen (68%) patients were on anti-hypertensives pre-procedure. Different types of stents were used (14 Valeo™, 4 Formula® 535, 1 BeGraft), which can all be dilated to 18 mm or larger. One patient required a 9 F sheath, all others required a 7 F sheath. The narrowest diameter in the aorta increased from a median of 3.5 [3.0-4.5] to 9.4 [8.9-9.8] mm, p < 0.001; there was a reduction in the median pressure gradient across the coarctation from 35.0 [30.0-43.0] to 5.0 [0-10.0] mmHg, p < 0.001. There were no intra-procedural complications. Follow-up was for a median of 56.0 [13.0-65.0] months. Five (26%) of patients underwent re-intervention after a median time frame of 40.0 [39.5-52.0] months; four had balloon dilation, one had repeat stent implantation. Five (26%) patients were on anti-hypertensive agent(s) post-intervention. Our single centre experience demonstrates that percutaneous stenting for coarctation of aorta in children under 30 kg, with low-profile stents, had no significant complications during the median follow-up time of 56 months. This study demonstrated that the procedure is safe and effective for short and medium-term therapy in this group of patients with a 26% re-intervention rate. A quarter of patients remained on anti-hypertensive medication post stenting, emphasizing the importance of long-term follow-up.

Abstract
Coarctation of the aorta (CoA) accounts for approximately 5-8% of all congenital heart defects. Depending on the severity of the CoA and the presence of associated cardiac lesions, the clinical presentation and age vary. Developments in diagnosis and management have improved outcomes in this patient population. Even after timely repair, it is important to regularly screen for hypertension. Patients with CoA require lifelong follow-up with a congenital heart disease specialist as these patients may develop recoarctation and complications at the repair site and remain at enhanced cardiovascular risk throughout their lifetime.

Stenting of branch pulmonary artery stenosis in children: initial experience and mid-term follow-up of the pul-stent. Heart Vessels 2023; 38:975-983. [PMID: 36820867 DOI: 10.1007/s00380-023-02246-9] [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: 11/24/2022] [Accepted: 01/26/2023] [Indexed: 02/24/2023]
Abstract
Not all stents are suitable for children. For instance, premounted stents can be used in infants and small children but cannot dilate with age to accommodate adult-sized pulmonary arteries. Conversely, the Pul-Stent adapts to somatic growth. Thus, our hospital implemented the Pul-Stent in pediatric patients with branch pulmonary artery stenosis. This study summarizes our initial experience with Pul-Stents in this patient population, including the efficacy and safety. We implanted 37 Pul-Stents in 35 patients between August 2014 and June 2015. The patients' mean age and weight at stent implantation were 6.7 ± 3.0 years and 20.9 ± 8.7 kg, respectively. Bench testing revealed that axial shortening of the Pul-Stent was minimal with further dilation, and the radial strength did not change. The stents were successfully deployed in all cases, except two with minor malpositioning. Primarily, 8-12 mm mounting balloons were used for the initial implantation, and a long sheath (8-10 F) was used for delivery. After stent implantation, the minimal lumen diameter in the stenosed segment increased by 50% in 97% (34/35) of patients. Furthermore, the pressure gradient across the stenosed segment decreased by 50% in 77% (23/30) of biventricular patients. One stent fracture and one stent restenosis were noted during the follow-up visits (mean follow-up time: 4.6 ± 1.7 years). Eighteen patients (51%) underwent repeat catheterization; ten had successful redilation. No aneurysms or stent fractures were observed. Our initial results indicate that the Pul-Stent is safe and effective in pediatric patients and can be further dilated over time to accommodate somatic growth. Moreover, the Pul-Stent has good compliance and adequate radial strength to treat pulmonary artery stenosis effectively.

Abstract
Determine outcomes of catheter intervention for aortic coarctation in infants. Aortic coarctation in infants following surgical repair and in high surgical risk native cases remains a challenging problem. Catheter intervention is an alternative to surgical intervention. Single-center, chart review of infants with biventricular anatomy who underwent coarctation stent placement or balloon angioplasty between 04/2004 and 04/2020. Outcomes of interest included change in aortic lumen diameter, peak gradient, number of re-interventions, time to re-intervention, and adverse events. Thirty-four patients were included in analysis, of those 16 underwent stent placement. Patients' mean age was 4.0 ± 3.0 months and weight of 5.3 ± 1.9 kg. Follow-up interval was 5.4 ± 5.1 years (0.2-16.1 years). Twelve (35%) patients underwent procedure due to ventricular dysfunction; the rest were for high resting gradient. Coarctation diameter increased from 2.4 ± 1.0 to 4.5 ± 1.3 (p < 0.01) and gradient decreased from 32.0 ± 18.4 mmHg to 9.2 ± 8.8 mmHg (p < 0.01). Thirteen (81%) of the stented patients required at least one re-intervention, at an average of 1.7 ± 3.2 years from the index procedure. Five (28%) of those undergoing balloon angioplasty required repeat intervention. There was no mortality due to the procedure and one late mortality. One patient had a serious procedural adverse event. On follow-up, 12 (35%) were on anti-hypertensive medications. Catheter intervention, including stent placement, for aortic coarctation in infants is feasible with an acceptable adverse event profile. Repeat interventions are common.

Abstract
BACKGROUND Stent implantation (SI) is more effective than balloon angioplasty for the treatment of coarctation of the aorta (CoA). Due to technical factors, balloon angioplasty is more commonly performed in small patients. We sought to evaluate outcomes of percutaneous adult sized SI for the treatment of CoA in small patients. METHODS A single-center retrospective review of all patients ≤20 kg who underwent percutaneous adult sized SI for native or recurrent CoA from 2004 to 2015 was performed. RESULTS Thirty-nine patients (20 patients ≤10 kg) were identified, with 28 (71.8%) having recurrent CoA and 22 (56.4%) previously failed balloon angioplasty. At the time of SI, the median (range) patient age and weight were 1.1 (0.3-7.9) years and 10 (5.5-20.4) kg, respectively. SI resulted in significant improvements in the median gradient (26 mm Hg [interquartile range (IQR), 18-42] to 0 mm Hg [IQR, 0-2]; P< 0.05) and median minimum diameter (3.6 mm [IQR, 2.4-4.8] to 7.7 mm [IQR, 6.5-9.4]; P<0.05). Seven patients (18%) had procedural adverse events. Twenty-seven (69%) patients underwent elective reintervention at a median time of 49.3 (IQR, 26.5-63.2) months from SI, with 8 (21%) stents requiring repeat SI for stent fracture. Over a median follow-up of 67.2 (IQR, 33.8-116.1) months, 25 patients (69%) were without hypertension or blood pressure gradient. Three (11%) patients developed femoral arterial occlusion. CONCLUSIONS Adult sized SI is an alternative to surgical intervention for small patients with CoA. SI carries a risk of access-related complications, which may improve with the development of lower profile stents with adult sized maximum diameters.

Abstract
Introduction Coarctation of the aorta in children under 3 months of age is usually treated surgically. However, there are clinical scenarios in which stenting of native or recurrent coarctation may become necessary in this age group. Case reports Four cases illustrate possible indications: left ventricular dysfunction increasing the operative risk, thrombus formation after coarctation surgery, patient size (i.e. in premature babies), and retrograde arch obstruction after hybrid palliation of hypoplastic left heart syndrome. In all babies, coarctation stenting was carried out successfully without complications. Conclusion Coarctation stenting can be carried out safely in small children. Usually, the stent has to be removed or redilated later. Results are encouraging.

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
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.
