Echocardiogram-Guided Balloon Valvuloplasty of the Aortic Valve in Neonates and Infants Reduces Contrast Exposure with Maintained Efficacy and Less Aortic Regurgitation. Pediatr Cardiol 2024; 45:1485-1492. [PMID: 37391604 DOI: 10.1007/s00246-023-03188-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Accepted: 05/14/2023] [Indexed: 07/02/2023]
Abstract
Balloon aortic valvuloplasty (BAV) is performed in children with significant aortic stenosis (AS). Traditionally, contrast angiography measures the annulus and assesses aortic regurgitation (AR) after each dilation. Echocardiographic guidance is hypothesized to reduce contrast and radiation exposure, without compromising efficacy or safety. Patients < 10 kg undergoing BAV from 2013 to 2022 were retrospectively investigated. Agreement between echocardiographic and angiographic annulus measurements was assessed. Echocardiogram-guided (eBAV) and traditional angiogram-guided (tBAV) outcomes were compared controlling for weight, critical AS, and other congenital heart disease (CHD). Twelve eBAV and 19 tBAV procedures were performed. The median age was 33 days, median weight was 4.3 kg, 7 patients (23%) had critical AS, and 9 patients (29%) had other CHD. Annulus measurements by intraprocedural echocardiography and angiography displayed excellent correlation (ICC 0.95, p < 0.001). eBAV patients received less contrast (0.5 vs 3.5 ml/kg, p < 0.01). Five recent eBAV procedures were performed contrast free. Radiation exposure was not statistically different between the eBAV and tBAV groups (155 vs 313 µGy·M2, p = 0.12). One eBAV patient (8%) and 3 tBAV patients (16%, p = 0.62) experienced serious adverse events. Technical success (gradient < 35 mmHg and increase in AR by ≤ 1 grade) occurred in 11 eBAV patients (92%) and 16 tBAV patients (84%, p = 0.22). AR increased in 2 eBAV patients (17%) and 8 tBAV patients (44%, p = 0.02). eBAV was associated with similar efficacy and significantly lower contrast exposure and risk of aortic regurgitation. There was strong agreement between aortic valve annulus measurements by intraprocedural echocardiography and angiography, ultimately permitting contrast free BAV.

Comparison between transcatheter versus surgical intervention for pediatric aortic valvular stenosis: a multicenter study in Japan. Heart Vessels 2024; 39:826-836. [PMID: 38704418 DOI: 10.1007/s00380-024-02403-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 04/03/2024] [Indexed: 05/06/2024]
Abstract
It is controversial whether children with isolated aortic valvular stenosis (vAS) initially undergo transcatheter or surgical aortic valvuloplasty (BAV or SAV). This multicenter retrospective case-control study aimed to explore outcomes after BAV or SAV for pediatric vAS. We studied children (aged < 15 years) with vAS treated at 4 tertiary congenital heart centers, and compared the rates of survival, reintervention, and valve replacement between patients with BAV and SAV. A total of 73 subjects (BAV: N = 52, SAV: N = 21) were studied. Age and aortic annulus z-score at the first presentation were 85 (26-530) days and - 0.45 (- 1.51-0.59), respectively. During the follow-up period of 121 (47-185) months, rates of 10-year survival (BAV: 88% vs. SAV: 92%, P = 0.477), reintervention (BAV: 58% vs. SAV: 31%, P = 0.626), and prosthetic/autograft valve replacement (BAV: 21% vs. SAV: 19%, P = 0.563) did not differ between the groups. Freedom from reintervention rate significantly correlated with aortic annulus z-score (hazard ratio [HR] 0.66, 95% confidence interval [CI] 0.49-0.88, P = 0.005), and freedom from prosthetic/autograft valve replacement rate significantly correlated to the degree of aortic regurgitation after the first intervention (HR: 4.58, 95% CI 1.19-17.71, P = 0.027). Propensity score-matched analysis (N = 16) did not show the differences in survival and reintervention rates between the groups. Long-term survival was acceptable, and the rates of freedom from reintervention and prosthetic/autograft valve replacement were comparable between children with vAS who underwent BAV and SAV.

Abstract
Congenital critical aortic valve stenosis (CAVS) is a life-threatening disease requiring urgent treatment. First-line therapy is still controversial. The aim of our study was (1) to analyze retrospectively the patients of our institution who underwent balloon aortic valvuloplasty (BAV) due to CAVS and (2) describe the techniques for improved feasibility of intervention using microcatheters and retrieval loops. Twelve patients underwent 23 BAVs: 1 BAV was performed in 3 patients, 2 BAVs were performed in 7 patients, and 3 BAVs were performed in 2 patients. The peak trans-valvular pressure gradient (Δp) and left ventricular shortening fraction (LVSF) improved significantly in the first two interventions. In the first BAV, Δp decreased from 73.7 ± 34.5 mmHg to 39.8 ± 11.9 mmHg (p = 0.003), and the LVSF improved from 22.3 ± 13.5% to 31.6 ± 10.2% (p = 0.001). In the second BAV, Δp decreased from 73.2 ± 33.3 mmHg to 35.0 ± 20.2 mmHg (p < 0.001), and the LVSF increased from 26.7 ± 9.6% to 33.3 ± 7.4% (p = 0.004). Cardiac surgery during the neonatal period was avoided for all children. The median time to valve surgery was 5.75 years. Few complications occurred, namely mild-to-moderate aortic regurgitation, one remediable air embolism, and one intimal injury to the ascending aorta. We conclude that BAV is a successful emergency treatment for CAVS, resulting in left ventricular relief, clinical stabilization, and a time gain until cardiac surgery.

Surgical aortic valvuloplasty is a better primary intervention for isolated congenital aortic stenosis in children with bicuspid aortic valve than balloon aortic valvuloplasty. Hellenic J Cardiol 2024; 77:54-62. [PMID: 37269944 DOI: 10.1016/j.hjc.2023.05.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 05/09/2023] [Accepted: 05/30/2023] [Indexed: 06/05/2023] Open
Abstract
OBJECTIVES Surgical aortic valvuloplasty (SAV) and balloon aortic valvuloplasty (BAV) are two main treatments for children with isolated congenital aortic stenosis (CAS). We aim to compare the two procedures' midterm outcomes, including valve function, survival, reintervention, and replacement. METHODS From January 2004 to January 2021, children with isolated CAS undergoing SAV (n = 40) and BAD (n = 49) at our institution were included in this study. Patients were also categorized into subgroups based on the aortic leaflet number(Tricuspid = 53, Bicuspid = 36) to compare the two procedures' outcomes. Clinical and echocardiogram data were analyzed to identify risk factors for suboptimal outcomes and reintervention. RESULTS Postoperative peak aortic gradient (PAG) and PAG at follow-up in the SAV group were lower compared with the BAV group (p < 0.001, p = 0.001, respectively). There was no difference in moderate or severe AR in the SAV group compared with the BAV group before discharge (5.0% vs 12.2%, p = 0.287) and at the last follow-up (30.0% vs 32.7%, p = 0.822). There were no early death but three late deaths (SAV = 2, BAV = 1). Kaplan-Meier estimated survivals were 86.3% and 97.8% in SAV and BAV groups respectively at 10 years (p = 0.54). There was no significant difference in freedom from reintervention (p = 0.22). For patients with bicuspid aortic valve morphology, SAV achieved higher freedom from reintervention (p = 0.011) and replacement (p = 0.019). Multivariate analysis indicated that residual PAG was a risk factor for reintervention (p = 0.045). CONCLUSIONS SAV and BAV achieved excellent survival and freedom from reintervention in patients with isolated CAS. SAV performed better in PAG reduction and maintenance. For patients with bicuspid AoV morphology, SAV was the preferred choice.

Abstract
OBJECTIVE To characterize national experience with surgical aortic valve repair in pediatric patients. METHODS Patients in the Pediatric Health Information System database aged 17 years or younger with International Statistical Classification of Diseases and Related Health Problems codes for open aortic valve repair from 2003 to 2022 were included (n = 5582). Outcomes of reintervention during index admission (repeat repair, n = 54; replacement, n = 48; and endovascular intervention, n = 1), readmission (n = 2176), and in-hospital mortality (n = 178) were compared. A logistic regression was performed for in-hospital mortality. RESULTS One-quarter (26%) of patients were infants. The majority (61%) were boys. Heart failure was present in 16% of patients, congenital heart disease in 73%, and rheumatic disease in 4%. Valve disease was insufficiency in 22% of patients, stenosis in 29%, and mixed in 15%. The highest quartile of centers by volume (median, 101 cases; interquartile range, 55-155 cases) performed half (n = 2768) of cases. Infants had the highest prevalence of reintervention (3%; P < .001), readmission (53%; P < .001), and in-hospital mortality (10%; P < .001). Previously hospitalized patients (median, 6 days; interquartile range, 4-13 days) were at higher risk for reintervention (4%; P < .001), readmission (55%; P < .001), and in-hospital mortality (11%; P < .001), as were patients with heart failure (reintervention [6%; P < .001], readmission [42%; P = .050], and in-hospital mortality [10%; P < .001]). Stenosis was associated with reduced reintervention (1%; P < .001) and readmission (35%; P = .002). The median number of readmissions was 1 (range, 0-6) and time to readmission was 28 days (interquartile range, 7-125 days). A regression of in-hospital mortality identified heart failure (odds ratio, 3.05; 95% CI, 1.59-5.49), inpatient status (odds ratio, 2.40; 95% CI, 1.19-4.82), and infancy (odds ratio, 5.70; 95% CI, 2.60-12.46) as significant. CONCLUSIONS The Pediatric Health Information System cohort demonstrated success with aortic valve repair; however, early mortality remains high in infants, hospitalized patients, and patients with heart failure.

Neonates and Infants with Left Heart Obstruction and Borderline Left Ventricle Undergoing Biventricular Repair: What Do We Know about Long-Term Outcomes? A Critical Review. Healthcare (Basel) 2024; 12:348. [PMID: 38338232 PMCID: PMC10855671 DOI: 10.3390/healthcare12030348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 01/22/2024] [Accepted: 01/23/2024] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND The decision to perform biventricular repair (BVR) in neonates and infants presenting with either single or multiple left ventricle outflow obstructions (LVOTOs) and a borderline left ventricle (BLV) is subject to extensive discussion, and limited information is known regarding the long-term outcomes. As a result, the objective of this study is to critically assess and summarize the available data regarding the prognosis of neonates and infants with LVOTO and BLV who underwent BVR. METHODS In February 2023, we conducted a review study with three different medical search engines (the National Library of Medicine, Science Direct, and Cochrane Library) for Medical Subject Headings and free text terms including "congenital heart disease", "outcome", and "borderline left ventricle". The search was refined by adding keywords for "Shone's complex", "complex LVOT obstruction", "hypoplastic left heart syndrome/complex", and "critical aortic stenosis". RESULTS Out of a total of 51 studies, 15 studies were included in the final analysis. The authors utilized heterogeneous definitions to characterize BLV, resulting in considerable variation in inclusion criteria among studies. Three distinct categories of studies were identified, encompassing those specifically designed to evaluate BLV, those focused on Shone's complex, and finally those on aortic stenosis. Despite the challenges associated with comparing data originating from slightly different cardiac defects and from different eras, our results indicate a favorable survival rate and clinical outcome following BVR. However, the incidence of reintervention remains high, and concerns persist regarding residual pulmonary hypertension, which has been inadequately investigated. CONCLUSIONS The available data concerning neonates and infants with LVOTO and BLV who undergo BVR are inadequate and fragmented. Consequently, large-scale studies are necessary to fully ascertain the long-term outcome of these complex defects.

Abstract
Aortic stenosis (AS) is a common form of left ventricular outflow tract obstruction (LVOTO) in children with congenital heart disease. This review specifically considers the perioperative features of valvar (VAS) and subvalvar AS (subAS) in the pediatric patient. Although VAS and subAS share some clinical features and diagnostic approaches, they are distinct clinical entities with separate therapeutic options, which range from transcatheter intervention to surgical repair. We detail the pathophysiology of AS and highlight the range of treatment strategies with a focus on anesthetic considerations for the care of these patients before, during, and after intervention.

Abstract
BACKGROUND Balloon valvuloplasty is the primary treatment for congenital aortic valve stenosis in our centre. We sought to determine independent predictors of reintervention (surgical repair or repeated balloon dilation) after primary valvuloplasty. METHODS We retrospectively studied patients with congenital aortic valve stenosis who underwent balloon valvuloplasty during 2004-2018. The following risk factors were analysed: aortic valve insufficiency after balloon valvuloplasty >+1/4, post-procedural gradient across the aortic valve ≥35 mmHg, pre-interventional gradient across the valve, annulus size, use of rapid pacing, and balloon/annulus ratio. Primary outcome was aortic valve reintervention. RESULTS In total, 99 patients (median age 4 years, range 1 day to 26 years) underwent balloon valvuloplasty for congenital aortic valve stenosis. After a mean follow-up of 4.0 years, 30% had reintervention. Adjusted risks for reintervention were significantly increased in patients with post-procedural aortic insufficiency grade >+1/4 and/or residual gradient ≥35 mmHg (HR 2.55, 95% CI 1.13-5.75, p = 0.024). Pre-interventional gradient, annulus size, rapid pacing, and balloon/annulus ratio were not associated with outcome. CONCLUSION Post-procedural aortic valve insufficiency grade >+1/4 and/or residual gradient ≥35 mmHg in patients undergoing balloon valvuloplasty for congenital aortic valve stenosis confers an increased risk for reintervention in mid-term follow-up.

Abstract
OBJECTIVES To support clinical decision-making in children with aortic valve disease, by compiling the available evidence on outcome after paediatric aortic valve repair (AVr). METHODS A systematic review of literature reporting clinical outcome after paediatric AVr (mean age at surgery <18 years) published between 1 January 1990 and 23 December 2021 was conducted. Early event risks, late event rates and time-to-event data were pooled. A microsimulation model was employed to simulate the lives of individual children, infants and neonates following AVr. RESULTS Forty-one publications were included, encompassing 2 623 patients with 17 217 patient-years of follow-up (median follow-up: 7.3 years; range: 1.0-14.4 years). Pooled mean age during repair for aortic stenosis in children (<18 years), infants (<1 year) or neonates (<30 days) was 5.2 ± 3.9 years, 35 ± 137 days and 11 ± 6 days, respectively. Pooled early mortality after stenosis repair in children, infants and neonates, respectively, was 3.5% (95% confidence interval: 1.9-6.5%), 7.4% (4.2-13.0%) and 10.7% (6.8-16.9%). Pooled late reintervention rate after stenosis repair in children, infants and neonates, respectively, was 3.31%/year (1.66-6.63%/year), 6.84%/year (3.95-11.83%/year) and 6.32%/year (3.04-13.15%/year); endocarditis 0.07%/year (0.03-0.21%/year), 0.23%/year (0.07-0.71%/year) and 0.49%/year (0.18-1.29%/year); and valve thrombosis 0.05%/year (0.01-0.26%/year), 0.15%/year (0.04-0.53%/year) and 0.19%/year (0.05-0.77%/year). Microsimulation-based mean life expectancy in the first 20 years for children, infants and neonates with aortic stenosis, respectively, was 18.4 years (95% credible interval: 18.1-18.7 years; relative survival compared to the matched general population: 92.2%), 16.8 years (16.5-17.0 years; relative survival: 84.2%) and 15.9 years (14.8-17.0 years; relative survival: 80.1%). Microsimulation-based 20-year risk of reintervention in children, infants and neonates, respectively, was 75.2% (72.9-77.2%), 53.8% (51.9-55.7%) and 50.8% (47.0-57.6%). CONCLUSIONS Long-term outcomes after paediatric AVr for stenosis are satisfactory and dependent on age at surgery. Despite a high hazard of reintervention for valve dysfunction and slightly impaired survival relative to the general population, AVr is associated with low valve-related event occurrences and should be considered in children with aortic valve disease.

Abstract
AIMS To support decision-making in children undergoing aortic valve replacement (AVR), by providing a comprehensive overview of published outcomes after paediatric AVR, and microsimulation-based age-specific estimates of outcome with different valve substitutes. METHODS AND RESULTS A systematic review of published literature reporting clinical outcome after paediatric AVR (mean age <18 years) published between 1/1/1990 and 11/08/2021 was conducted. Publications reporting outcome after paediatric Ross procedure, mechanical AVR (mAVR), homograft AVR (hAVR), and/or bioprosthetic AVR were considered for inclusion. Early risks (<30d), late event rates (>30d) and time-to-event data were pooled and entered into a microsimulation model. Sixty-eight studies, of which one prospective and 67 retrospective cohort studies, were included, encompassing a total of 5259 patients (37 435 patient-years; median follow-up: 5.9 years; range 1-21 years). Pooled mean age for the Ross procedure, mAVR, and hAVR was 9.2 ± 5.6, 13.0 ± 3.4, and 8.4 ± 5.4 years, respectively. Pooled early mortality for the Ross procedure, mAVR, and hAVR was 3.7% (95% CI, 3.0%-4.7%), 7.0% (5.1%-9.6%), and 10.6% (6.6%-17.0%), respectively, and late mortality rate was 0.5%/year (0.4%-0.7%/year), 1.0%/year (0.6%-1.5%/year), and 1.4%/year (0.8%-2.5%/year), respectively. Microsimulation-based mean life-expectancy in the first 20 years was 18.9 years (18.6-19.1 years) after Ross (relative life-expectancy: 94.8%) and 17.0 years (16.5-17.6 years) after mAVR (relative life-expectancy: 86.3%). Microsimulation-based 20-year risk of aortic valve reintervention was 42.0% (95% CI: 39.6%-44.6%) after Ross and 17.8% (95% CI: 17.0%-19.4%) after mAVR. CONCLUSION Results of paediatric AVR are currently suboptimal with substantial mortality especially in the very young with considerable reintervention hazards for all valve substitutes, but the Ross procedure provides a survival benefit over mAVR. Pros and cons of substitutes should be carefully weighed during paediatric valve selection.

Abstract
BACKGROUND Valve repair is the procedure of choice for congenital aortic valve disease. With increasing experience, the surgical armamentarium broadened from simple commissurotomy to more complex techniques. We report our 30-year experience with pediatric aortic valve repair. METHODS A retrospective chart review of all patients aged less than 18 years who underwent aortic valve repair from May 1985 to April 2020 was conducted. Mortality was cross-checked with the national health insurance database (96% complete mortality follow-up in April 2020). Primary study endpoints were survival and incidence of reoperations. RESULTS From May 1985 until April 2020, 126 patients underwent aortic valve repair at a median age of 1.8 years (interquartile range, 0.2-10). Early mortality was 5.6% (7 of 126). All early deaths occurred in neonates with critical aortic stenosis undergoing commissurotomy. No early deaths were observed after 2002. Kaplan-Meier estimated survival was 90.8% (95% CI, 84.0-94.8) at 10 years, 86.9% (95% CI, 78.7-92.2) at 20 years, and 83.5% (95% CI, 71.7-90.6) at 30 years. The cumulative incidence of aortic valve replacement was 37% (95% CI, 27.7-46.3) at 10 years, 62.2% (95% CI, 50.1-72.1) at 20 years, and 67.4% (51.2-79.2) at 30 years. Nine patients had undergone re-repair of the aortic valve. The majority of valve replacements were Ross procedures. CONCLUSIONS Our results support a repair-first strategy for patients with congenital heart disease and underline that aortic valve reconstruction can be a successful long-term solution. Longevity did not differ between aortic valve commissurotomy and complex aortic valve reconstruction.

Abstract
Almost 90% of infants with congenital heart disease (CHD) now reach adulthood but require long-term surveillance to recognize and manage residual and/or evolving lesions. Yet many are lost to follow-up. A scoping review identified four specific domains that pose barriers to consistent follow-up. There are multiple issues associated with transition from pediatric to adult care which included-the lack of a seamless transfer, the establishment of a new trusting relationship, promoting the right balance of patient autonomy and addressing knowledge gaps. Additional issues related to logistic problems of time, distance, cost, and the availability of specialized care, are further compounded by the psychosocial factors and the heterogeneity of the cardiac abnormality affecting our patients. Further study of all these issues is warranted to improve ongoing engagement.

Abstract
OBJECTIVE To compare long-term survival, reinterventions and risk factors using strict definitions of neonatal critical and non-critical valvular aortic stenosis (VAS). DESIGN A nationwide retrospective study using data from patient files, echocardiograms and the Swedish National Population Registry. SETTING AND PATIENTS All neonates in Sweden treated for isolated VAS 1994-2018. We applied the following criteria for critical aortic stenosis: valvular stenosis with duct-dependent systemic circulation or depressed left ventricular function (fractional shortening ≤27%). Indication for treatment of non-critical VAS was Doppler mean gradient >50 mm Hg. MAIN OUTCOME MEASURES Short-term and long-term survival, aortic valve reinterventions need of valve replacements, risk factors for reintervention and event-free survival. RESULTS We identified 65 patients with critical VAS and 42 with non-critical VAS. The majority of the neonates were managed by surgical valvotomy. Median follow-up time was 13.5 years, with no patients lost to follow-up. There was no 30-day mortality. Long-term transplant-free survival was 91% in the critical stenosis group and 98% in the non-critical stenosis group (p=0.134). Event-free survival was 40% versus 67% (p=0.002) in the respective groups. Median time from the initial treatment to reintervention was 3.6 months versus 3.9 years, respectively (p=0.008). CONCLUSIONS Critical VAS patients had significantly higher need for reintervention during the first year of life, lower event-free survival and lower freedom from aortic valve replacement at age ≥18 years, compared with neonates with non-critical stenosis.

Abstract
OBJECTIVE The Ross procedure is an important tool that offers autologous tissue repair for severe left ventricular outflow tract (LVOT) pathology. Previous reports show that risk of mortality is highest among neonates and infants. We analyzed our institutional experience within this patient cohort to identify factors that most affect clinical outcome. METHODS A retrospective chart review identified all Ross operations in neonates and infants at our institution over 27 years. The entire study population was analyzed to determine risk factors for mortality and define outcomes for survival and reintervention. RESULTS Fifty-eight patients underwent a Ross operation at a median age of 63 (range, 9-156) days. Eighteen (31%) were neonates. Eleven (19%) patients died before hospital discharge. Multiple regression analysis of the entire cohort identified young age (hazard ratio [HR], 1.037; P = .0045), Shone complex (HR, 17.637; P = .009), and interrupted aortic arch with ventricular septal defect (HR, 16.01; P = .031) as independent predictors of in-hospital mortality. Receiver operating characteristic analysis (area under the curve, 0.752) indicated age younger than 84 days to be the inflection point at which mortality risk increases. Of the 47 survivors, there were 2 late deaths with a mean follow-up of 6.7 (range, 2.1-13.1) years. Three patients (6%) required LVOT reintervention at 3, 8, and 17.5 years, respectively, and 26 (55%) underwent right ventricular outflow tract reintervention at a median of 6 (range, 2.5-10.3) years. CONCLUSIONS Ross procedure is effective in children less than one year of age with left sided obstructive disease isolated to the aortic valve and/or aortic arch. Patients less than 3 months of age with Shone or IAA/VSD are at higher risk for morbidity and mortality. Survivors experience excellent intermediate-term freedom from LVOT reintervention.

Abstract
Aim: To evaluate outcomes of interventions for severe aortic valve stenosis (AS), whether it is done by surgical aortic valvotomy (SAV) or balloon aortic dilatation (BAD). Results: Eleven studies with total number of 1733 patients; 743 patients had SAV, while 990 patients received BAD. There was no significant difference in early mortality (odds ratio [OR]: 0.96, p = 0.86), late mortality (OR: 1.28, p = 0.25), total mortality (OR: 1.10, p = 0.56), and freedom from aortic valve replacement (OR: 1.00, p = 1.00). Reduction of aortic systolic gradient was significantly higher in the SAV group (OR: 2.24, p = 0.00001), and postprocedural AR rate was lower in SAV group (OR: 0.21, p = 0.00001). Conclusion: SAV is associated with better reduction of aortic systolic gradient and lesser post procedural AR which reduce when compared with BAD.

Abstract
Background Studies on the long-term outcomes of children with congenital aortic stenosis who underwent primary aortic repair are limited. We reviewed the long-term outcomes of children who underwent aortic valve (AoV) repair at our center. Methods All children (n = 75) who underwent AoV repair between 2006 and 2020 were reviewed. The Kaplan-Meier curve was used to demonstrate the survival estimates. The Cox proportional hazard model and competing risk regression model were used to identify risk factors for death, reintervention, adverse events, and replacement. Results The median age at surgery was 1.8 (IQR, 0.2–7.7) years, and the median weight at surgery was 10.0 (IQR, 5.0–24.0) kg. Early mortality and late mortality were 5.3% (4/75) and 5.6% (4/71), respectively. Risk factors for overall mortality were concomitant mitral stenosis (P = 0.01, HR: 9.8, 95% CI: 1.8–53.9), low AoV annulus Z-score (P = 0.01, HR: 0.6, 95% CI: 0.4–0.9), and prolonged cardiopulmonary bypass time (P < 0.01, HR: 9.5, 95% CI: 1.7–52.1). Freedom from reintervention was 72.9 ± 0.10% (95% CI: 56.3–94.4%) at 10 years. Risk factors for occurrence of adverse event on multivariable analysis included preoperative intubation (P = 0.016, HR: 1.004, 95% CI: 1.001–1.007) and a low AoV annulus Z-score (P = 0.019, HR: 0.714, 95% CI: 0.540–0.945). Tricuspid AoV morphology was associated with a suboptimal postoperative outcome (P = 0.03). Conclusion Aortic valve repair remains a safe and durable solution for children with congenital aortic stenosis. Concomitant mitral stenosis and aortic valve anatomy, including tricuspid valve morphology and smaller annulus size, are associated with poor early and long-term outcomes.

Abstract
This study assessed outcomes of neonatal aortic valve (AoV) repair in presumed high-risk patients with depressed left ventricular (LV) function. A retrospective analysis of all neonates who underwent isolated AoV repair for severe aortic stenosis (AS) was performed. Patients with moderate or severe LV dysfunction were compared to those with normal or mild LV dysfunction. From 1980-2021, 43 neonates underwent isolated AoV repair for AS. Of these, 16 patients (37.2%) had ≥moderate LV dysfunction. Mean LV ejection fraction (EF) was 32.8 ± 9.1%. Valve morphology was mostly unicuspid (68.75%, 11/16). Median age at surgery was 6.5 days (IQR 1-17.5). An optimal repair result with ≤mild AS or aortic regurgitation was achieved in 75% (12/16). There was no early death. One patient (6.25%) required postoperative extracorporeal membrane oxygenation (ECMO) support for 3 days. LVEF improved after surgery to 56.4 ± 12.6% before discharge (P < 0.0001) and normalized in 87.5% (14/16) with a median time of 6.4 days (IQR 3.4-39). Freedom from AoV reoperation was 45.1% (95%CI 17.9-69.3%) and 27.1% (95%CI 6.8-53%) at 5 and 10 years, respectively. Freedom from AoV replacement was 59% (95%CI 27-80.8%) and 31.4% (95%CI 6-62.2%) at 5 and 10 years, respectively. While survival was similar, freedom from AoV reoperation and replacement tended to be lower compared to neonates with preserved LVEF. AoV repair was associated with a low incidence of postoperative ECMO and mortality. LV function normalized after relief of obstruction in most patients before discharge. Late reoperation remained common for those with severely dysplastic valves.

Abstract
Background The optimal initial treatment pathway for aortic valve stenosis remains debated. Objectives The objective of this study was to review current outcomes of balloon aortic valvotomy (BAV) in neonates and infants. Methods Neonates and infants with a biventricular circulation treated with BAV between 2004 and 2019 were reviewed. Results One hundred thirty-nine infants (48% neonates) with median (Q1, Q3) age of 33(7, 84) days and weight 4.0 (3.4, 5.1) kg were followed up for 7.1 (3.3, 11.0) years. BAV reduced peak-to-peak gradient from mean (SD) 52 (16) mmHg to 18 (12) mmHg; P < 0.001. Aortic regurgitation (AI) increased with time after BAV. Three children died during follow-up. Fifty-one reinterventions (26 BAV, 19 aortic valve replacements [AVRs], and 6 surgical valvotomies) were performed on 40 children. Freedom from AVR (95% CI) was 96% (93%-99%) at 1, 91% (86%-96%) at 5, and 86% (79%-93%) at 10 years. The predictors of AVR were a unicommissural valve (hazard ratio [HR] [95% CI]: 3.7 [1.4-9.6]; P = 0.007) and moderate to severe AI after index BAV (HR [95% CI]: 3.3 [1.1-9.7]; P = 0.029). Freedom from reintervention was 84% (78%-90%) at 1, 76% (69%-83%) at 5, and 69% (60-78%) at 10 years. Main predictors of reintervention were age below 1 month (HR [95% CI]: 2.1 [1.1-4.1]; P = 0.032) and postdilation peak-to-peak gradient (per 10-mmHg increase; HR [95% CI]: 1.36 [1.02-1.79]; P = 0.032). Conclusions BAV is a safe and effective treatment for aortic valve stenosis in neonates and infants. Outcomes are competitive with contemporary published data on aortic valve repair in relation to mortality, gradient relief, long-term AVR, and reintervention rates. In the absence of significant AI, surgery can be reserved for those with gradients resistant to valve dilation.

Abstract
BACKGROUND Balloon valvuloplasty and surgical aortic valvotomy have been the treatment mainstays for congenital aortic stenosis in children. Choice of intervention often differs depending upon centre bias with limited relevant, comparative literature. OBJECTIVES This study aims to provide an unbiased, contemporary matched comparison of these balloon and surgical approaches. METHODS Retrospective analysis of patients with congenital aortic valve stenosis who underwent balloon valvuloplasty (Queensland Children's Hospital, Brisbane) or surgical valvotomy (Royal Children's Hospital, Melbourne) between 2005 and 2016. Patients were excluded if pre-intervention assessment indicated ineligibility to either group. Propensity score matching was performed based on age, weight, and valve morphology. RESULTS Sixty-five balloon patients and seventy-seven surgical patients were included. Overall, the groups were well matched with 18 neonates/25 infants in the balloon group and 17 neonates/28 infants in the surgical group. Median age at balloon was 92 days (range 2 days - 18.8 years) compared to 167 days (range 0 days - 18.1 years) for surgery (rank-sum p = 0.08). Mean follow-up was 5.3 years. There was one late balloon death and two early surgical deaths due to left ventricular failure. There was no significant difference in freedom from reintervention at latest follow-up (69% in the balloon group and 70% in the surgical group, p = 1.0). CONCLUSIONS Contemporary analysis of balloon aortic valvuloplasty and surgical aortic valvotomy shows no difference in overall reintervention rates in the medium term. Balloon valvuloplasty performs well across all age groups, achieving delay or avoidance of surgical intervention.

Abstract
Background
This study aims to compare the success, complications, and long-term outcomes of aortic balloon valvuloplasty and surgical aortic valvuloplasty in pediatric patients with congenital aortic valve stenosis.
Methods
Between March 2000 and October 2019, a total of 267 procedures, including 238 balloon valvuloplasties and 29 surgical valvuloplasties, in 198 children (135 males, 63 females; mean age: 57.4±62.6 months; range, 0.03 to 219 months) were retrospectively analyzed. The hospital records, echocardiographic images, catheterization data, angiography images, and operative data were reviewed.
Results
Aortic regurgitation was mild in 73 patients before balloon valvuloplasty, and none of the patients had moderate-to-severe aortic regurgitation. Compared to surgical valvuloplasty, the rate of increase in the aortic regurgitation after balloon valvuloplasty was significantly higher (p=0.012). The patients who underwent balloon valvuloplasty did not need reintervention for a mean period of 46±45.6 months, whereas this period was significantly longer in those who underwent surgical valvuloplasty (mean 80.5±53.9 months) (p=0.018). The overall failure rate was 8%. Moderate-to-severe aortic regurgitation was the most important complication developing due to balloon valvuloplasty in the early period (13%). All surgical valvuloplasties were successful. The mean length of hospitalization after balloon valvuloplasty was significantly shorter than surgical valvuloplasty (p=0.026). During follow-up, a total of 168 patients continued their follow-up, and a reinterventional or surgical intervention was not needed in 78 patients (47%).
Conclusion
Aortic balloon valvuloplasty can be repeated safely and helps to eliminate aortic valve stenosis without needing sternotomy. Surgical valvuloplasty can be successfully performed in patients in whom the expected benefit from aortic balloon valvuloplasty is not achieved.

Abstract
According to the results of modern researchers, the main techniques used in congenital pathology of the aortic valve in children include balloon catheter dilatation of the aortic valve, surgical valvuloplasty, the Ross procedure and replacement of the aortic valve with a mechanical prosthesis. Many surgeons point out that these techniques in congenital pathology of the aortic valve yield suboptimal results. This is often due to the lack of a clear-cut definition between surgeons as to what operation should be performed in a particular age group. According to the reports of the majority of researchers, biological prostheses undergo early degeneration and structural changes in paediatric cardiac surgery and yield the worst results. Comparing the main techniques, optimal haemodynamics is observed after the Ross procedure. A disadvantage of this operation is the necessity of repeat intervention on the right ventricular outflow tract, which is required in 20 to 40%. Concomitant surgery of the mitral valve and/or aortic arch during the Ross procedure significantly increases the lethality and the risk of postoperative complications. Compared with an adult cohort of patients, children after prosthetic repair of the aortic valve using a mechanical prosthesis are more often found to have postoperative complications and a higher mortality rate. Yet another problem encountered in paediatric valve surgery is the unavailability of commercial prostheses sized ?19 mm. The duration of the intraoperative parameters for reconstructions of the aortic valve, the Ross procedure, and replacement of the aortic valve by the results of many studies averagely amounts to 74±34 min, 100±56 min, and 129±71 min, respectively. Yet another method which can be used for neocuspidization of the aortic valve in reconstructive surgery of the aortic root in paediatric patients is the use of glutaraldehyde-treated autologous pericardium. In our opinion, given the simplicity of the procedure, duration of the intraoperative parameters, and acceptable initial results reported by some researchers, the Ozaki procedure may be performed in children.

Abstract
BACKGROUND For children with congenital aortic stenosis (AS) who are candidates for biventricular repair, valvuloplasty can be achieved by surgical aortic valvuloplasty (SAV) or by transcatheter balloon aortic dilation (BAD). We aimed to evaluate the longer term outcomes of SAV versus BAD at our institution. METHODS We retrospectively reviewed the outcomes of 2 months to 18 years old patients who underwent SAV or BAD at our institution between January 1990 and July 2018. Baseline and follow-up characteristics were assessed by echocardiography. Long-term survival, freedom from reintervention, freedom from aortic valve replacement (AVR), and aortic regurgitation were evaluated. RESULTS A total of 212 patients met inclusion criteria (SAV = 123; BAD = 89). Age, sex, aortic insufficiency (AI), and aortic valve gradient were similar between the groups. At 10 years, 27.9% (19/68) of SAV patients and 58.3% (28/48) of BAD patients had moderate or worse AI (P = .001), and reintervention occurred in 39.2% (29/74) of SAV patients and 78.6% (44/56) of BAD patients (P < .001). Kaplan-Meier analysis revealed overall survival was 96.8% (119/123) for SAV and 95.5% (85/89) for SAV (P = .87). At 10 years, 35% (23/66) of SAV patients and 54% (23/43) of BAD patients underwent AVR (P = .213). CONCLUSIONS Surgical aortic valvuloplasty demonstrated greater gradient reduction, less postoperative and long-term AI, and a lower reintervention rate at 10 years than BAD. There was no difference in survival or AVR reintervention rate. Surgical aortic valvuloplasty is a durable and efficacious intervention and should continue to be considered a favorable choice for palliation of valvular AS.

Abstract
The left ventricular outflow tract (LVOT) comprises of the subvalvular area, the aortic valve, and the supravalvular region. Obstructive lesion of LVOT is a spectrum with varying levels and degree of obstruction with or without associated hypoplasia of the left ventricle. Decision-making in small and borderline LVOT can be challenging. Imaging modalities such as echocardiography and magnetic resonance imaging and scores based on imaging aid in the decision making in truly borderline cases. Newer treatment strategies like staged left ventricular rehabilitation and hybrid procedure have come to the fore in the past decade or so. Although these do not address small LVOT per se, they delay the decision-making to a more appropriate age. The goal of management in these cases is to achieve a biventricular repair whenever feasible. Several surgical techniques could be employed to achieve this goal. However, it is important to be cognizant of the fact that an overzealous approach to achieve a biventricular repair might be counterproductive. A univentricular palliation could be a safer alternative; especially considering the possibility of a future transplant candidacy.

[PMID: 33516462 DOI: 10.1016/j.jtcvs.2020.11.159] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 10/23/2020] [Accepted: 11/22/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND We aimed to assess the long-term outcomes of children in whom the aortic valve could be repaired without the use of patch material. We hypothesized that if the aortic valve is of sufficiently good quality to perform repair without patches, a durable repair could be achieved. METHODS All children (n = 102) who underwent aortic valve repair without the use of a patch between 1980 and 2016 were reviewed. RESULTS The median patient age at operation was 2 years (interquartile range, 1 month to 9.6 years). There were 25 neonates and 17 infants. There was no operative mortality. Mean overall survival at 10 years was 97.7% ± 0.01% (95% confidence interval, [CI] 91.0%-99.4%). Forty-three patients (42.2%) required 56 aortic valve reoperations, including 24 redo aortic valve repairs, 22 Ross procedures, 8 mechanical aortic valve replacements, and 2 homograft aortic valve replacements. Mean freedom from aortic valve reoperation at 10 years was 57.4% ± 0.06% (95% CI, 44.9%-68.1%), and freedom from aortic valve replacement at 10 years was 74.5% ± 0.05% (95% CI, 63.0%-82.9%) at 10 years. Freedom from aortic valve reoperation at 10 years was 33.1% ± 0.1% (95% CI, 14.5%-53.2%) in neonates and 68.9% ± 0.06% (95% CI, 54.5%-79.6%) in older children (P < .01). CONCLUSIONS In approximately one-third of children undergoing aortic valve repair, the repair could be achieved without patches. In these children, aortic valve repair was achieved without operative mortality. Infants and older children have low reoperation rates, whereas reoperation rates in neonates are higher. Initial repair allows valve replacement to be delayed to later in childhood, when a more durable result may be achieved.

Rapid right ventricular pacing for balloon aortic valvuloplasty: expanding its routine use in neonates and infants. Cardiol Young 2020; 30:1890-1895.

Abstract
OBJECTIVE Rapid right ventricular pacing during balloon aortic valvuloplasty is commonly used to achieve balloon stability in children and adults. There is no consensus for the use of the technique in neonates and infants. We sought to review our institutional experience with rapid right ventricular pacing-assisted balloon aortic valvuloplasty across all age groups and evaluate the safety and effectiveness of the technique in the sub-group of neonates and infants <12months. METHODS Retrospective study between February, 2011 and February, 2020. RESULTS A total of 37 patients (Group I: 21 neonates/infants <12months and Group II: 16 children 12 months-16 years) were analysed. Catheter-measured left ventricular to aortic gradient reduced from median of 66 mmHg (with a range from 30 to 125 mmHg) to 14 mmHg (with a range from 5 to 44 mmHg) in Group I and 44 mmHg (with a range from 28 to 93 mmHg) to 18 mmHg (with a range from 2 to 65 mmHg) in Group II (p < 0.001). Procedure and fluoroscopy times were identical in the two groups. Balloon:annulus ratio was 0.94 and 0.88 in Groups I and II, respectively. Freedom from reintervention was 100% for Group I at a median time of 3.2 years and 81% at 2.7 years for Group II. Reinterventions in Group II (3/16 pts) were performed predominantly for complex left ventricular outflow tract stenosis. At follow-up echocardiogram, 45% of patients in Group I had no aortic regurgitation, 30% trace-mild, 20% mild-moderate, and 5% moderate aortic regurgitation, whereas in Group II, 50% of patients had no aortic regurgitation, 32% had mild aortic regurgitation, and 18% mild-moderate aortic regurgitation. Unicuspid valves were only encountered in Group 1 (2/21 pts, 10%) and they were predictive of mild-aortic regurgitation during follow-up (p = 0.003). Ventricular fibrillation occurred in three neonates with suspicion of myocardial ischemia on the pre-procedure echocardiogram. All were successfully defibrillated. CONCLUSIONS Rapid right ventricular pacing can be expanded in neonates and infants to potentially decrease the incidence of aortic regurgitation and reintervention rates, hence avoiding high-risk surgical bail-out procedures for severe aortic regurgitation in the first year of life. Myocardial ischemia may predispose to ventricular dysrhythmias during rapid right ventricular pacing.

Abstract
BACKGROUND For patients with congenital aortic valve stenosis (AVS), comprehensive analysis of surgical aortic valvuloplasty (SAV) or balloon dilation (BD) is scarce and remains controversial. METHODS This study reviewed AVS data (aortic peak gradient, aortic insufficiency, and survival and reoperation) for patients who were suitable for biventricular repair at our center in 2008 to 2018. Patients were categorized into two subgroups based on age (≤3 or >3 months). RESULTS A total of 194 patients were treated, including 124 with SAV and 70 with BD. Resulting data revealed that residual aortic gradient at discharge was worse for BD (p = 0.001). While for patients younger than 3 months, the relief of AVS was comparable between the two groups (p = 0.624). There was no significant difference in time-related survival between the two groups (log-rank p = 0.644). Multivariate analysis demonstrated that preoperative left ventricular end-diastolic dimension predicted early death (p = 0.045). Survival in the two groups after 10 years was 96.8% in SAV and 95.7% in BD (p = 0.644). Freedom from reoperation after 10 years was 58.1% in SAV and 41.8% in BD patients (p = 0.01). There was no significant difference in freedom from reoperation between SAV and BD in patients younger than 3 months (p = 0.84). Multivariate analysis indicated that residual aortic peak gradient was predictive of reoperation (p = 0.038). CONCLUSION Both methods achieved excellent survival outcomes at our center. SAV achieved superior gradient reduction and minimized the necessity for reoperation. For patients younger than 3 months, BD rivaled SAV both in aortic stenosis relief and freedom from reoperation.

Abstract
OBJECTIVE This study describes short-term and long-term outcome after treatment of critical valvular aortic stenosis in neonates in a national cohort, with surgical valvotomy as first choice intervention. METHODS All neonates in Sweden treated for critical aortic stenosis between 1994 and 2016 were included. Patient files were analysed and cross-checked against the Swedish National Population Registry as of December 2017, giving complete survival data. Diagnosis was confirmed by reviewing echo studies. Critical aortic stenosis was defined as valvular stenosis with duct-dependent systemic circulation or depressed left ventricular function. Primary outcome was all-cause mortality and secondary outcomes were reintervention and aortic valve replacement. RESULTS Sixty-one patients were identified (50 boys, 11 girls). Primary treatment was surgical valvotomy in 52 neonates and balloon valvotomy in 6. Median age at initial treatment was 5 days (0-26), and median follow-up time was 10.8 years (0.14-22.6). There was no 30-day mortality but four late deaths. Freedom from reintervention was 66%, 61%, 54%, 49%, and 46% at 1, 5, 10, 15, and 20 years, respectively. Median time to reintervention was 3.4 months (4 days to 17.3 years). Valve replacement was performed in 23 patients (38%). CONCLUSIONS Surgical valvotomy is a safe and reliable treatment in these critically ill neonates, with no 30-day mortality and long-term survival of 93% in this national study. At 10 years of age, reintervention was performed in 54% and at end of follow-up 38% had had an aortic valve replacement.

Abstract
Bicuspid aortic valve (BAV) is one of the most common congenital heart defects in children, adolescents and adults. BAV can occur as an isolated lesion or in association with other congenital heart defects, such as coarctation of the aorta or genetic syndromes like Turner syndrome. Although the majority of long term complications associated with BAV manifest later in life, children and adolescents may present with early onset valvular dysfunction or dilation of the aorta. BAV is a heterogeneous disease with a wide array of presentations at various ages, depending on the degree of aortic valve dysfunction, aortic dilation and presence of associated lesions. Aortic valve stenosis and/or regurgitation are the primary indications for intervention in children and adolescents with BAV. Although a majority of young patients with BAV also have some aortic dilation, interventions on the aorta are very rare during this time frame. Children and adolescents with BAV benefit from comprehensive assessment of their risk profile to determine follow-up surveillance intervals, sports recommendations, and timing of surgical intervention. The morphologic phenotype of BAV is important to identify, as it may predict future complications and prognosis.

Abstract
In cardiovascular surgery, reconstruction and replacement of cardiac and vascular structures are routinely performed. Prosthetic or biological materials traditionally used for this purpose cannot be considered ideal substitutes as they have limited durability and no growth or regeneration potential. Tissue engineering aims to create materials having normal tissue function including capacity for growth and self-repair. These advanced materials can potentially overcome the shortcomings of conventionally used materials, and, if successfully passing all phases of product development, they might provide a better option for both the pediatric and adult patient population requiring cardiovascular interventions. This short review article overviews the most important cardiovascular pathologies where tissue engineered materials could be used, briefly summarizes the main directions of development of these materials, and discusses the hurdles in their clinical translation. At its beginnings in the 1980s, tissue engineering (TE) was defined as “an interdisciplinary field that applies the principles of engineering and the life sciences toward the development of biological substitutes that restore, maintain, or improve tissue function” (1). Currently, the utility of TE products and materials are being investigated in several fields of human medicine, ranging from orthopedics to cardiovascular surgery (2–5). In cardiovascular surgery, reconstruction and replacement of cardiac and vascular structures are routinely performed. Considering the shortcomings of traditionally used materials, the need for advanced materials that can “restore, maintain or improve tissue function” are evident. Tissue engineered substitutes, having growth and regenerative capacity, could fundamentally change the specialty (6). This article overviews the most important cardiovascular pathologies where TE materials could be used, briefly summarizes the main directions of development of TE materials along with their advantages and shortcomings, and discusses the hurdles in their clinical translation.

Abstract
BACKGROUND Balloon aortic valvuloplasty and open surgical valvotomy are procedures to treat neonatal aortic stenosis, and there is controversy as to which method has superior outcomes. METHODS We reviewed the records of patients at our institution since 2000 who had a balloon aortic valvuloplasty or surgical valvotomy via an open commissurotomy prior to 2 months of age. RESULTS Forty patients had balloon aortic valvuloplasty and 15 patients had surgical valvotomy via an open commissurotomy. There was no difference in post-procedure mean gradient by transthoracic echocardiogram, which were 25.8 mmHg for balloon aortic valvuloplasty and 26.2 mmHg for surgical valvotomy, p = 0.87. Post-procedure, 15% of balloon aortic valvuloplasty patients had moderate aortic insufficiency and 2.5% of patients had severe aortic insufficiency, while no surgical valvotomy patients had moderate or severe aortic insufficiency. The average number of post-procedure hospital days was 14.2 for balloon aortic valvuloplasty and 19.8 for surgical valvotomy (p = 0.52). Freedom from re-intervention was 69% for balloon aortic valvuloplasty and 67% for surgical valvotomy at 1 year, and 43% for balloon aortic valvuloplasty and 67% for surgical valvotomy at 5 years (p = 0.60). CONCLUSIONS Balloon aortic valvuloplasty and surgical valvotomy provide similar short-term reduction in valve gradient. Balloon aortic valvuloplasty has a slightly shorter but not statistically significant hospital stay. Freedom from re-intervention is similar at 1 year. At 5 years, it is slightly higher in surgical valvotomy, though not statistically different. Balloon aortic valvuloplasty had a higher incidence of significant aortic insufficiency. Long-term comparisons cannot be made given the lack of long-term follow-up with surgical valvotomy.

Abstract
OBJECTIVES This study presents short- and long-term follow-up after treatment for isolated valvular aortic stenosis in children with surgical valvotomy as the preferred 1st intervention. METHODS All patients aged 0-18 years treated between 1994 and 2013 at our centre were reviewed regarding the mode of first treatment, mortality, reinterventions and the need for aortic valve replacement. RESULTS A total of 113 patients were identified in local registries. There were 44 neonates, 31 infants and 38 children. The mean follow-up period was 11 years (range 2-22 years). No early deaths and only 2 late deaths were reported. Of the 113 patients, 92 patients had open surgical valvotomy as the 1st intervention. Freedom from reintervention was 80%, 69%, 61%, 57% and 56% at 1, 5, 10, 15 and 20 years, respectively. The main indication for reintervention was valvular stenosis. Freedom from aortic valve replacement was 67%. CONCLUSIONS Surgical valvotomy of aortic stenosis in this long-term follow-up study resulted in no 30-day mortality and <1% late mortality. Reinterventions were common, with 38% of the patients having further surgery or catheter treatment of the aortic valve before the age of 18 years. Among the 40 patients aged 18 years or older at follow-up, 45% had had the aortic valve replaced. Our data do not allow comparison of catheter and surgical treatment, but, based on these results, we find no reason to change our current policy of surgical treatment as 1st intervention in patients with isolated valvular aortic stenosis.

Abstract
Aortic valve stenosis in children is a congenital heart defect that causes fixed form of hemodynamically significant left ventricular outflow tract obstruction with progressive course. Neonates and young infants who have aortic valve stenosis, usually develop congestive heart failure. Children and adolescents who have aortic valve stenosis, are mostly asymptomatic, although they may carry a small but significant risk of sudden death. Transcatheter or surgical intervention is indicated for symptomatic patients or those with moderate to severe left ventricular outflow tract obstruction. Many may need reintervention.

Abstract
Objective There are conflicting data on choosing balloon aortic valvoplasty (BAV) or surgical aortic valvotomy (SAV) in neonates and infants requiring intervention for aortic valve stenosis. We aim to report the outcome of both techniques based on results from the UK national registry. Methods This is a retrospective study, including all patients under 1 year undergoing BAV/SAV between 2000 and 2012. A modulated renewal approach was used to examine the effect of reinterventions on outcomes. Results A total of 647 patients (488 BAV, 159 SAV, 292 neonates) undergoing 888 aortic valve procedures were included, with a median age of 40 days. Unadjusted survival at 10 years was 90.6% after initial BAV and 84.9% after initial SAV. Unadjusted aortic valve replacement (AVR) rate at 10 years was 78% after initial BAV and 80.3% after initial SAV. Initial BAV and SAV had comparable outcomes at 10 years when adjusted by covariates (p>0.4). AVR rates were higher after BAV and SAV reinterventions compared with initial valvoplasty without reinterventions (reference BAV, HR=3 and 3.8, respectively, p<0.001). Neonates accounted for 29/35 of early deaths after the initial procedure, without significant differences between BAV and SAV, with all late outcomes being worse compared with infants (p<0.005). Conclusions In a group of consecutive neonates and infants, BAV and SAV had comparable survival and freedom from reintervention as initial procedures and when performed as reinterventions. These findings support a treatment choice based on patient characteristics and centre expertise, and further research into the best patient profile for each choice.
