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
Aortic wall injuries may occur after interventional treatment of aortic coarctation (CoA), especially after balloon angioplasty. We reported on a patient who presented with an intra-stent aneurysm formation after direct stenting of a native near atretic aortic CoA by using a BeGraft Aortic stent. This evidence supports the need to maintain a strict follow-up protocol. A computed tomography scan is mandatory, after covered stent implantation as well, especially in high-risk cases and even in the absence of any immediate apparent complication.

Abstract
We report our experience and early outcomes of using the BeGraft aortic stent in children, adolescents, and young adults. BeGraft aortic stent (Bentley InnoMed, Hechingen, Germany) requires a smaller long sheath compared to other covered stents, and it has a low profile and adequate radial power. With these features, it can overcome some limitations in the treatment of coarctation, especially in children. This is a single centre retrospective analysis of 11 implanted BeGraft aortic stents in coarctation of the aorta between July 2020 and November 2021. The eleven stents were successfully implanted in 11 patients (10 males). The median age of the patients was 13.7 years (interquartile range 12-16 years), and the median weight was 43 kg (interquartile range 35-62 kg). In five patients, after the stents were opened completely by the first balloon, they were exchanged with a Z-MED II™ balloon, 1-3 mm larger in diameter, and the stents were redilated. The median catheter-derived systolic peak-to-peak pressure gradient was 23 mm Hg (interquartile range 16-37 mmHg) before the procedure and 3 mm Hg (interquartile range 1-5 mm Hg) after the procedure. Except for the partial femoral artery thrombosis in two patients, no other procedural complications were observed in our study. The median follow-up duration was 5 months (interquartile range 2-12 months). During follow-up, only one patient (9%) had stent narrowing that required dilation. Our initial results and short-term follow-up showed that the BeGraft aortic stent implantation and redilation can be performed effectively, safely, and successfully in the treatment of coarctation of the aorta.

Abstract
OBJECTIVES To evaluate bare-metal Optimus and polytetrafluoroethylene (PTFE)-covered Optimus-CVS balloon-expandable, cobalt-chromium, hybrid cell-designed stents in congenital heart disease (CHD) interventions. METHODS Retrospective multicentre review of patients with CHD receiving Optimus stents. Stent mechanical behaviour, clinical indications and outcomes were assessed. RESULTS 183 stents (49.2% XXL/15-ZIG, 33.3% XL/12-ZIG, 17.5% L/9-ZIG) were implanted (98.9% success rate, 2.3% serious procedural complication rate) in 170 patients (57.6% men, 64.1% adults), median age 23.6 years (IQR, 15.2-39.2) and weight 63.5 kg (IQR, 47-75.7). Indications were right ventricular outflow tract stand-alone stenting or before revalvulation (62.4%), aortic coarctation treatment (15.3%), Fontan-circuit fenestration closure (12.4%) and miscellaneous (10%). 86/170 (50.6%) patients had PTFE-covered stenting (50% prophylactic). In 86/170 (50.6%) patients with stenotic lesions, median percentage of achieved stent expansion was 93.4% (IQR, 85.5%-97.7%), median gradient decreased from 28 mm Hg (IQR, 19-41) to 5 mm Hg (IQR, 1-9) (p<0.001), median vessel diameters increased from 13 mm (IQR, 7.9-17) to 18.9 mm (IQR, 15.2-22) (p<0.001) and percentage of vessel expansion was 45.2% (IQR, 19.8%-91.3%). In 30/36 (83.3%) patients with graft, median dilation of 2 mm (IQR, 2-5) above nominal diameter was achieved. Median stent shortening was 10.9% (IQR, 6.1-15.1) and was associated only with expansion diameter (OR: 0.66, 95% CI: 0.38 to 0.93). No clinically relevant fracture, stent embolisation or dysfunction occurred on a median follow-up of 9 (IQR, 4-14) months. CONCLUSIONS Optimus stents are effective tools for transcatheter treatment of simple and complex CHD. Optimus stents' reliable mechanical behaviour and particular covering design can promote widespread use.

Abstract
A 22-year-old man was referred to our hospital for rib notching found on a radiograph and hypertension. Computed tomography revealed coarctation of the descending aortic isthmus. Because he refused open surgery, endovascular treatment was performed. The 2-year follow-up computed tomography scan showed infolding of the stent graft and thrombus formation. He had presented with intermittent claudication; therefore, graft interposition was performed. Endovascular surgery plays an important role in the treatment of coarctation of the aorta. However, insufficient dilatation can lead to restenosis accompanied by thrombus formation, and excess ballooning can cause aortic wall injury. Careful performance of the procedure and close postoperative follow-up are essential.

Abstract
BACKGROUND Coarctation of the aorta with poststenotic aneurysms is rare and complex. Here we report a relatively large group of endovascular treatments for the disease. MATERIALS AND METHODS Fifteen patients from two centers between 2006 and 2019 were included in the study. The patients were retrospectively divided into two groups. Patients in the complex group had insufficient proximal landing zone (<2 cm) or the zigzag shape of aorta. Their demographics, clinical manifestations, endovascular procedures, and follow-up results were analyzed. RESULTS There were 7 patients in the simple group and 8 patients in the complex group. Eleven patients were symptomatic. Despite the unfavorable anatomy in the complex group, technical success reached 100%. The diameter of coarctation increased from 8.6 mm to 16.7 mm with poststenotic aneurysms successfully excluded at the same time. In patients without sufficient proximal landing zone, left subclavian artery was covered by the stent grafts and then sacrificed (three patients) or revascularized (four patients). Other than one patient who suffered iliac artery rupture and received open repair, there was no other perioperative complications. Computed tomography angiography repeated at mean 42 months postoperation confirmed patency of stents and the exclusion of aneurysms with no aortic wall injury. Mild endoleaks occurred in two patients in the complex group and were left to observation. During 55.0 months follow-up, except for one patient who received secondary left subclavian artery fenestration, all other patients remained asymptomatic. CONCLUSIONS Endovascular treatments for coarctation of the aorta with poststenotic aneurysm showed a high technical success and could be an alternative solution for such disease.

Endovascular treatment of aortic coarctation with a novel BeGraft aortic stent in children and young adults: a single-centre experience with short-term follow-up results.

Abstract
OBJECTIVES We present our experience and outcomes with the BeGraft in the treatment of aortic coarctation in a predominantly paediatric population. METHODS This study includes a retrospective analysis of patients who had Begraft aortic stent implantation between 2018 and 2020 from a single centre. RESULTS The BeGraft aortic stent was used in 11 patients (7 males, 4 females) with a median age of 14 (13-21) years and a median weight of 65 (46-103) kg. Coarctation was native in five patients and recurrent in six patients. Median stent diameter and length were 16 mm and 38 mm, respectively. The median peak-to-peak pressure was 30 (12-55) mmHg before the procedure and 5 (0-17) mmHg after the procedure. The stenting procedure was successful in 10 of the 11 patients. Stent migration to the abdominal aorta occurred on post-procedure day 1 in the 21-year-old patient, who had previously undergone surgical closure of the ventricular septal defect and balloon angioplasty for coarctation. After repositioning failed, the stent was safely fixed in the abdominal aorta. Strut distortion also occurred during balloon retrieval in one patient, but no aneurysm or in-stent restenosis was observed at 1-year follow-up. The patients were followed for a median of 14 (4-25) months and none required redilation. CONCLUSIONS Our initial results demonstrated that the BeGraft aortic stent effectively reduced the pressure gradient in selected native and recurrent cases. Despite advantages such as a smaller sheath and low profile, more experience and medium- to long-term results are needed.

Abstract
PURPOSE OF REVIEW Coarctation of the aorta remains a controversial topic with uncertainties in long-term outcomes. RECENT FINDINGS Recent advances in fetal imaging including echocardiography and MRI offer novel opportunities for better detection and prediction of the need for neonatal intervention.New imaging techniques are providing novel insights about the impact of arch geometry and size on flow dynamics and pressure gradients. The importance of arch size rather than shape for optimal hemodynamics has been identified. Long-term outcome data suggest a significant increase in mortality risk in coarctation patients beyond the third decade when compared with the general population. Hypertension is highly prevalent not only in adult patients following repair of coarctation but also in normotensive patients presenting with LV diastolic dysfunction and adverse remodelling, indicating that abnormal vascular properties are important. Patients with coarctation undergoing neonatal repair are at risk for adverse neurodevelopmental outcomes and patients could benefit from timely neurocognitive evaluation and intervention. SUMMARY Optimizing aortic arch size, prevention and aggressive treatment of hypertension and vascular stiffening are important to improve long-term outcomes.
