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.

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
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
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
Supplemental Digital Content is available in the text. Background: Aortic valve stenosis is the most common type of congenital left ventricular (LV) outflow tract obstruction. Balloon aortic valvuloplasty (BAV) has become the first-line treatment pathway in many centers. Our aim was to assess the trajectory of LV remodeling following BAV in children and its relationship to residual aortic stenosis (AS) and insufficiency (AI). Methods: Children <18 years of age who underwent BAV for isolated aortic stenosis from 2004 to 2012 were eligible for inclusion. Those with AI before BAV, other complex congenital heart lesions, or <2 accessible follow-up echocardiograms were excluded. Baseline and serial echocardiographic data pertaining to aortic valve and LV size and function were retrospectively collected through December 2017 or the first reintervention. Longitudinal data was assessed using per-patient time profiles with superimposed trend lines using locally estimated scatterplot smoothing. Associations with reintervention or death were also evaluated. Results: Among the 98 enrolled children, the median (interquartile range) age at BAV was 2.8 months (0.2–75). The median (interquartile range) follow-up was 6.8 years (1.9–9.0). Children with predominantly residual AI (n=11) demonstrated progressive increases in their LV end-diastolic dimension Z score within the first 3 years after the BAV, followed by a plateau (P<0.001). Their mean LV circumferential and longitudinal strain values remained within the normal range but lower than in the non-AI group (P<0.001 and P=0.001, respectively). Children with predominantly residual aortic stenosis (n=44) had no changes in LV dimensions but had a rapid early increase in mean LV circumferential and longitudinal strain. The cumulative proportion (95% CI) of reintervention at 5 years following BAV was 33.7% (23.6%–42.4%). Conclusions: Our study demonstrates that LV remodeling occurs mainly during the first 3 years in children with predominantly residual AI after BAV, with no subsequent significant functional changes over the medium term. These data improve our understanding of expected patient trajectories and thus may inform decisions on the timing of reintervention.

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 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
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
BACKGROUND Optimal initial treatment for congenital aortic valve stenosis in children remains unclear between balloon aortic valvuloplasty (BAV) and surgical aortic valvotomy (SAV). METHODS AND RESULTS We performed a contemporary systematic review and meta-analysis to compare survival in children with congenital aortic valve stenosis. Secondary outcomes included frequency of at least moderate regurgitation at hospital discharge as well as rates of aortic valve replacement and reintervention. Single- and dual-arm studies were identified by a search of PubMed (Medline), Embase, and the Cochrane database. Overall 2368 patients from 20 studies were included in the analysis, including 1835 (77%) in the BAV group and 533 (23%) in the SAV group. There was no difference between SAV and BAV in hospital mortality (OR=0.98, 95% CI 0.5-2.0, P=0.27, I(2)=22%) or frequency of at least moderate aortic regurgitation at discharge (OR=0.58, 95% CI 0.3-1.3, P=0.09, I(2)=54%). Kaplan-Meier analysis showed no difference in long-term survival or freedom from aortic valve replacement but significantly more reintervention in the BAV group (10-year freedom from reintervention of 46% [95% CI 40-52] for BAV versus 73% [95% CI 68-77] for SAV, P<0.001). Results were unchanged in a sensitivity analysis restricted to infants (<1 year of age). CONCLUSIONS Although higher rates of reintervention suggest improved outcomes with SAV, indications for reintervention may vary depending on initial intervention. When considering the benefits of a less-invasive approach, and clinical equipoise with respect to more clinically relevant outcomes, these findings support the need for a randomized controlled trial.
