ABSTRACT

The present study aimed to evaluate the outcomes of percutaneous treatment of aortic coarctation using self-expandable uncovered Nitinol stents. We conducted a retrospective clinical data review of all patients with aortic coarctation and treated with self-expandable uncovered Nitinol stents at our institution between 2009 and 2019. The gradient pressure across the coarctation site was measured using aortography. Follow-up echocardiography and computed tomography angiography were performed to assess possible stent complications. A total of 127 stents were successfully implanted in 125 patients (64.8% males) with a mean age of 35.36 ± 11.9 years. The gradient across the coarctation site decreased significantly from 67.48 ± 14.79 to 5.04 ± 3.01 mmHg (P < 0.001) after self-expandable stent implantation. Systolic blood pressure (SBP) decreased significantly from 175.53 ± 15.99 to 147.22 ± 12.83 mmHg (P < 0.001) after self-expandable stenting. There were no major technical or clinical complications, including balloon rupture, aneurysmal formation, infection, secondary stent migration, thrombosis, death during the procedure, and in-hospital mortality. On a mean follow-up of 48 ± 23.6 months (12-120 months), the gradient [from 59.43 ± 15.42 to 3.72 ± 1.38 mmHg (P < 0.001)] and SBP [from 175.53 ± 15.99 to 127.99 ± 7.82 mmHg (P < 0.001)] decreased significantly. There was no mortality, aneurysmal formation in the stent site, dislocation, or aortic re-stenosis requiring intervention during mid-term follow-up. Treatment of aortic coarctation using a self-expandable uncovered nitinol stent is safe and effective with promising mid-term outcomes.

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.

ABSTRACT

BACKGROUND: Endovascular treatment of aortic coarctation (CoA) in children and adults frequently requires stent implantation. The aim of this study was to analyze long-term results after CoA treatment with bare and covered Cheatham-PlatinumTM (CP) stents in our institution and to derive recommendations for the differential use of these stent types. METHODS: In this retrospective single institution study, 212 patients received endovascular CoA treatment with bare (n = 71) and covered (n = 141) CP stents between September 1999 and July 2021, respectively. The indications for treatment were native CoA in 110/212 patients (51.9%) and re-coarctation after primary surgical or interventional treatment in 102/212 patients (48.1%). Median patient age at endovascular CoA treatment was 18.8 years [IQR 11.9; 35.8]. Long-term follow-up was available in 158/212 patients (74.5%) with a median follow-up of 7.3 years [IQR 4.3; 12.6]. RESULTS: Procedural success was achieved in 187/212 (88.2%) patients. Survival rate was 98.1% after 5, and 95.6% after 10 and 15 years, respectively. The probability of freedom from re-intervention was 93.0% after 5, 82.3% after 10 and 77.8% after 15 years, respectively. Freedom from re-interventions (44/158, 27.8%) did not differ between patients who received bare or covered CP stents (p = 0.715). Multivariable risk factor analysis identified previous CoA surgery (HR: 2.0, 95% confidence interval (CI): 1.1-3,9, p = 0.029), postdilatation (HR: 2,9, 95% CI: 1.1-6.3, p = 0.028) and age at intervention (HR: 0.96, 95% CI: 0.94-0.99, p = 0.002) as independent risk factors for re-intervention. Peri-procedural complications occurred in 15/212 (7.1%) patients (dissection/thrombosis of vascular access vessel: n = 9; bleeding: n = 1; stent dislocation: n = 2; aortic dissection/aortic wall rupture: n = 3). Long-term complications were observed in 36 patients and included stent fracture (n = 19), aneurysm formation (n = 14), endoleak (n = 1) and subclavian artery stenosis (n = 2). Peri-procedural and long-term complications did not differ between patients who received CoA treatment with bare or covered CP stents (all p > 0.05). CONCLUSION: Endovascular treatment of CoA using bare or covered CP stents can be performed safely and effectively with excellent long-term results. Survival, re-intervention and complication rate did not significantly differ between both stent types. However, individual stent selection is advisable with regard to CoA morphology and severity as well as patient age.

ABSTRACT

BACKGROUND: Covered stent (CS) use for the transcatheter treatment of coarctation of the aorta (COA) was first described over 20 years ago. The covered Cheatham-platinum stent received Food and Drug Administration approval for COA treatment in 2016. Data collected as part of the National Cardiovascular Data Registry IMPACT registry were evaluated for contemporary usage patterns of CS for the treatment of COA from 2016 to 2021. METHODS: Version 2 of the IMPACT registry was queried for all patients who underwent stent placement for treatment of COA from 2016 to 2021. Trends in CS use were evaluated by year and age of patient at the time of implant. Analysis was limited to clinical factors collected as part of the registry and was performed to identify factors associated with CS use. RESULTS: Data were available for 1989 case entries. Most patients (92%) received a single stent. The overall percentage of CS use in the cohort was 23% and remained consistent throughout the study period. The probability of CS use was significantly associated with increasing patient age at implant. Additional factors associated with CS use included smaller initial COA diameter, native COA, and the presence of a pseudoaneurysm. Procedural adverse event rates were low. CONCLUSIONS: CS use to treat COA was more common in adult patients and remained stable over the study period. Factors associated with CS use, including smaller COA diameter and aortic pseudoaneurysm, demonstrate the perceived value of CS as a tool to reduce the risk of aortic wall injury during treatment of COA.

ABSTRACT

Coarctation of aorta (CoA) is a common congenital anomaly which portends patients to early diastolic and systolic heart failure. In this retrospective cohort study, we aimed to evaluate the impact of CoA on heart failure hospitalization. Using the national inpatient sample, the study compared the outcomes of heart failure hospitalization between patients with and without CoA. We noted increasing prevalence of CoA related heart failure admissions over the last decade. Heart failure patients with CoA were younger (mean age 57 vs 71.6 years, P < 0.001), had a longer length of stay (7.4 vs 5.4 days, P < 0.001), and a higher incidence of cardiogenic shock (6.5% vs 2.1%, P = 0.001). However, there was no statistically significant difference in in-hospital mortality (OR 1.45, 95% CI: 0.58, 3.62, P = 0.421) between both groups. These findings demonstrate that CoA increase healthcare resource utilization in patients admitted with heart failure without any significant increase in in-hospital mortality.

ABSTRACT

Turner syndrome (TS) is a chromosomal disorder that affects 25-50 per 100,000 live born females. Patients with TS face a heavy burden of cardiovascular disease (congenital and acquired) with an increased risk of mortality and morbidity compared to the general population. Cardiovascular diseases are a major cause of death in females with TS. Approximately 50% of TS patients have a congenital heart abnormality, with a high incidence of bicuspid aortic valve, coarctation of the aorta and generalised arteriopathy. Frequently, females with TS have systemic hypertension, which is also a risk factor for progressive cardiac dysfunction and aortopathy. This paper aims to provide an overview of the cardiovascular assessment, management and follow up strategies in this high-risk population.

ABSTRACT

We present the first clinical experience with a new hybrid cell structure covered stent, designed for congenital heart disease applications. It represents a significant redesign of the Cheatham Platinum (CP) Stent (Numed Inc.), maintaining the traditional benefits of the covered CP whilst significantly decreasing shortening and allowing controlled flaring at the ends through its combination of larger and standard sized cells. We first implanted the stent in 2 patients with superior sinus venosus defects with anomalous drainage of the right upper and middle lobe pulmonary veins. The first was a 40 year male and the second a 36 year old female. The third case was a 60 year old patient with near atresia of the aorta, with pre and poststenotic aortic dilation. The clinical result in all cases was excellent with no obstruction to pulmonary venous return and no visible L-R shunt on the transthoracic echo on 24 h and 2 week follow-up for the patient with sinus venosus defects and uniform complete revascularization of the aorta without any vascular complications in the patient with coarctation. These are the first uses of this stent in human subjects. The design is specifically aimed toward procedures where stent shortening is undesirable. Hence, coarctation of the aorta as well as stent implantation in preparation for percutaneous pulmonary valve placement are obvious use areas, as well as the growing body of evidence supporting percutaneous treatment of sinus venosus defects.

ABSTRACT

This case reports describe a rare disease, mid-aortic syndrome (MAS), that can cause severe heart failure and hypertension in infancy. The typical images, key points of diagnosis, and therapy methods of the disease have also been presented. We report two critical thoracoabdominal aortic coarctation cases in infants aged 2 and 11 months with severe heart failure. The patients were initially misdiagnosed as dilated myocardiopathy, with the correct diagnosis confirmed through imaging. Both patients underwent balloon angioplasty; one patient also had bare-metal stents implanted. The patient treated with balloon angioplasty alone died after the procedure, whereas the other patient recovered well. In conclusion, careful physical examinations, especially upper and lower extremity blood pressure differences and palpation of upper and lower limb pulses, are critical in unexplained infant heart failure cases. Stent implantation may be a safer and more effective treatment than simple balloon angioplasty in infants with MAS.

ABSTRACT

Coarctation of the aorta (Coa) is a potentially life threatening diagnosis. It occurs in 0.3 per 1000 live births and accounts for 6-8% of all infants with congenital heart defects. Neonates with severe Coa may be completely asymptomatic at birth, as the ductus arteriosus can provide flow to the lower body. Those who are not diagnosed prenatally may be diagnosed only after constriction of the ductus arteriosus, when they present in cardiogenic shock. This group has a higher risk for mortality and morbidity relative to those diagnosed prenatally. Despite the increasing practice of universal pulse oximetry screening, many cases with significant coarctation of the aorta still go undiagnosed in the newborn period. In this article, we present the pathophysiology, diagnosis, presentation, treatment and outcomes of Coa.

ABSTRACT

To assess the efficacy and safety of a breakable BabyStent to treat complex aortic coarctation (CoA) in early childhood. Although recommended in several guidelines, there is no approved aortic stent for young infants, because of the dilemma between two mandatory requirements: expandable up to adult size on the one hand, and small enough to fit through a baby's femoral artery on the other. Prospective interventional, multi-center clinical trial with the breakable Osypka BabyStent® (OBS). The OBS is a low-profile, 15-mm long cobalt-chromium stent, pre-mounted on a 6 mm balloon and inserted via a 4 Fr sheath. After implantation, its diameter is adjustable from 6 to 12 mm by balloon dilation. Further dilation opens predefined joints enabling unrestricted growth. Nineteen patients (9 male), median age 112 days (range: 7-539), median body weight 5.6 kg (range: 2.4-8.4) were deemed high risk and underwent stent implantation. Of those, 74% suffered from re-CoA following surgery, 53% had additional cardiac and 21% noncardiac malformations. Our primary combined endpoint was fulfilled: All stents were implanted in the desired region, and a >50% intrastenotic diameter-extension was achieved in 15 patients (78.9%, 80% confidence interval [62.2; 90.5], 95% confidence interval [54.4; 93.9]). Secondary endpoint confirmed that the OBS fits the baby's femoral vessel diameter. All children survived the procedure and 12-month follow-up. This stent enables percutaneous stenting of complex aortic coarctation to treat high-risk newborns and infants.

ABSTRACT

OBJECTIVES: This study sought to compare the safety and efficacy of the balloon-expandable stent (BES) and the self-expandable stent (SES) in the endovascular treatment of coarctation of aorta. BACKGROUND: Coarctoplasty with stents has conferred promising results. Although several nonrandomized studies have approved the safety and efficacy of the BES and the SES, no high-quality evidence exists for this comparison. METHODS: In the present open-label, parallel-group, blinded endpoint randomized pilot clinical trial, adult patients with de novo native aortic coarctation were randomized into Cheatham-platinum BES and uncovered nitinol SES groups. The primary outcome of the study was a composite of procedural and vascular complications. The secondary outcomes of the study consisted of the incidence of aortic recoarctation, thoracic aortic aneurysm/pseudoaneurysm formation, and residual hypertension at a 12-month follow-up. RESULTS: Among 105 patients who were screened between January 2017 and December 2019, 92 eligible patients (32 women [34.8%]) with a median age of 30 years (IQR: 20-36 years) were randomized equally into the BES and SES groups. The composite of procedural and vascular complications occurred in 10.9% of the BES group and 2.2% of the SES group (odds ratio: 0.18; 95% CI: 0.02-1.62; P = 0.20). Aortic recoarctation occurred in 5 patients (5.4%), 3 patients (6.5%) in the BES group and 2 patients (4.3%) in the SES group (odds ratio: 0.65; 95% CI: 0.10-4.09; P = 0.64). Only 1 patient (1.1%) was complicated by aortic pseudoaneurysm. Hypertension control was achieved in 50% of the study population, with an equal distribution in the 2 study groups at the 12-month follow-up. CONCLUSIONS: Both the BES and the SES were safe and effective in the treatment of native coarctation.

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

OBJECTIVE: Coarctation of the Aorta (CoA) is a relatively common cardiovascular disorder. The present study aimed to evaluate the effect of COA anatomy and high versus low-pressure balloons on the outcome of balloon angioplasty among neonates and infants. METHODS: In this retrospective study, the neonates and infants undergoing balloon angioplasty at Namazi hospital were enrolled. After balloon angioplasty, immediate data results were promptly recorded.Moreover, midterm echocardiographic information was collected via electronic cardiac records of pediatric wards and clinical and echocardiographic data at least 12 months after balloon angioplasty. Finally, data were analyzed using SPSS-20. RESULTS: In this study, 42 infants were included. The median age at the time of balloon angioplasty was 1.55 (range 0.1-12) months and 66.7% of the patients were male. The mean pressure gradient of coarctation was 38.49 ± 24.97 mmHg, which decreased to 7.61 ± 8.00 mmHg (P < 0.001). A high-pressure balloon was used in 27, and a low-pressure balloon was used in 15 patients. COA's pressure gradient changed 30.89 ± 18.06 in the high-pressure group and 24.53 ± 20.79 in the low-pressure balloon group (P = 0.282). In the high-pressure balloon group, 14.81% and in the low-pressure group, 33.33% had recoarctation and need second balloon angioplasty (p < 0.021). The infant with discrete coarctation had a higher decrease in gradient and lower recoarctation. CONCLUSION: Recoarctation rate was lower in the high-pressure balloon. The infant with discrete COA had a better response to the balloon with more decrease in gradient and lower recoarctation rate. Therefore, the stenotic segment anatomy needs to be considered in the selection of treatment methods.

ABSTRACT

We describe a 9-day-old baby with coarctation of the aorta who required urgent resuscitation including intubation and cardiac compressions. Despite the commencement of prostaglandin E1 (PGE1) to reopen the ductus arteriosus via the intraosseous route, postductal saturations remained unrecordable for a further 45 min. Within 3 min of administration of PGE1 via an umbilical venous catheter (UVC), saturations were recordable at 92%. UVC access was the sentinel intervention that irrevocably altered the clinical prognosis. This baby boy has survived with excellent neurodevelopmental outcome. Clinicians are less familiar with UVCs outside of the newborn period. Our data demonstrate successful placement in neonates up to 28 days of age. We hope this case encourages clinicians to consider the UVC as first-line central venous access in collapsed neonates. In cases of suspected left heart obstruction, we argue that UVCs are the optimal route.

ABSTRACT

OBJECTIVE: To test the hypothesis that a fetal stratification pathway will effectively discriminate between infants at different levels of risk for surgical coarctation and reduce unnecessary medicalization. STUDY DESIGN: We performed a pre-post nonrandomized study in which we prospectively assigned fetuses with prenatal concern for coarctation to 1 of 3 risk categories and implemented a clinical pathway for postnatal management. Postnatal clinical outcomes were compared with those in a historical control group that were not triaged based on the pathway. RESULTS: The study cohort comprised 109 fetuses, including 57 treated along the fetal coarctation pathway and 52 historical controls. Among mild-risk fetuses, 3% underwent surgical coarctation repair (0% of those without additional heart defects), compared with 27% of moderate-risk and 63% of high-risk fetuses. The combined fetal aortic, mitral, and isthmus z-score best discriminated which infants underwent surgery (area under the curve = 0.78; 95% CI, 0.66-0.91). Compared with historical controls, infants triaged according to the fetal coarctation pathway had fewer delivery location changes (76% vs 55%; P = .025) and less umbilical venous catheter placement (74% vs 51%; P = .046). Trends toward shorter intensive care unit stay, hospital stay, and time to enteral feeding did not reach statistical significance. CONCLUSIONS: A stratified risk-assignment pathway effectively identifies a group of fetuses with a low rate of surgical coarctation and reduces unnecessary medicalization in infants who do not undergo aortic surgery. Incorporation of novel measurements or imaging techniques may improve the specificity of high-risk criteria.
