Comparison between transcatheter versus surgical intervention for pediatric aortic valvular stenosis: a multicenter study in Japan. Heart Vessels 2024:10.1007/s00380-024-02403-8.

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.

Balloon aortic valvuloplasty in neonates: short- and long-term effects and predictors of successful outcome. Adv Cardiol 2022; 18:154-161. [PMID: 36051839 PMCID: PMC9421511 DOI: 10.5114/aic.2022.118532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Accepted: 06/11/2022] [Indexed: 11/17/2022]
Abstract
Introduction Balloon aortic valvuloplasty (BAV) is a common treatment method of aortic valve (AV) stenosis in neonates. Long-term BAV effects are suboptimal, and their predictors are not well acknowledged. Aim To identify predictors of suboptimal short- and long-term BAV results. Material and methods The study group comprised forty-three neonates (8 females; weight 3.34 ±0.56 kg) who underwent BAV between 1998 and 2021. Seventeen patients (39.53%) had critical AV stenosis. AV was bicuspid in 22 patients, tricuspid in 12, unicuspid in 2, and undefined in 7 patients. The mean balloon/annulus ratio was 0.9 ±0.07. Catheterization, clinical, and follow-up data were analysed. Results The peak-to-peak gradient decreased from 67.5 ±26.3 to 21.3 ±12.6 mm Hg. Twenty-eight patients (65.1%) had adequate early outcome. Aortic regurgitation (AR) occurred in 13 (30.2%) patients. No predictors of inadequate early outcome were found. Twenty-year survival was 90.7%. Eleven (35.5%) patients underwent reintervention at a median of 12 (1–215) months; BAV in 5 patients, surgical valvuloplasty in 2, Ross operation in 2, AV replacement in 1, and Norwood operation in 1 patient. Fifteen-year freedom from reintervention (FFR) was 48%. Adequate early outcome resulted in higher FFR (71% vs. 22%), and so did no significant AR (60% vs. 30%). Conclusions BAV provides satisfying early results. AR remains a significant aftermath of BAV. Risk factors and procedural techniques improving the outcome of BAV are unclear. Further research is needed to improve FFR.

Balloon Valvuloplasty for Congenital Aortic Stenosis: Experience at a Tertiary Center in a Developing Country. J Interv Cardiol 2021; 2021:6681693.

Abstract
Background Aortic valve stenosis accounts for 3–6% of congenital heart disease. Balloon aortic valvuloplasty (BAV) is the preferred therapeutic intervention in many centers. However, most of the reported data are from developed countries. Materials and Methods We performed a retrospective single-center study involving consecutive eligible neonates and infants with congenital aortic stenosis admitted for percutaneous BAV between January 2005 and January 2016 to our tertiary center. We evaluated the short- and mid-term outcomes associated with the use of BAV as a treatment for congenital aortic stenosis (CAS) at a tertiary center in a developing country. Similarly, we compared these outcomes to those reported in developed countries. Results During the study period, a total of thirty patients, newborns (n = 15) and infants/children (n = 15), underwent BAV. Left ventricular systolic dysfunction was present in 56% of the patients. Isolated AS was present in 19 patients (63%). Associated anomalies were present in 11 patients (37%): seven (21%) had coarctation of the aorta, two (6%) had restrictive ventricular septal defects, one had mild Ebstein anomaly, one had Shone's syndrome, and one had cleft mitral valve. BAV was not associated with perioperative or immediate postoperative mortality. Immediately following the valvuloplasty, a more than mild aortic regurgitation was noted only in two patients (7%). A none-to-mild aortic regurgitation was noted in the remaining 93%. One patient died three months after the procedure. At a mean follow-up of 7 years, twenty patients (69%) had more than mild aortic regurgitation, and four patients (13%) required surgical intervention. Kaplan–Meier freedom from aortic valve reintervention was 97% at 1 year and 87% at 10 years of follow-up. Conclusion Based on outcomes encountered at a tertiary center in a developing country, BAV is an effective and safe modality associated with low complication rates comparable to those reported in developed countries.

Abstract
OBJECTIVE To evaluate treatment outcomes of pediatric valvar aortic stenosis (AS) in a nationwide follow-up. DESIGN Balloon aortic valvuloplasty (BAV) has been the preferred treatment for congenital AS in Finland since the year 2000. All children treated due to isolated AS during 2000-2014 were included in this retrospective study. Treatment outcomes were categorized into Optimal: residual gradient ≤35 mmHg and trivial or no aortic regurgitation (AR), Adequate: gradient ≤35 mmHg with mild AR, or Inadequate: gradient >35 mmHg and/or moderate to severe AR. RESULTS Sixty-one patients underwent either BAV (n = 54) or surgical valvuloplasty (n = 7) for valvar AS at a median age of 29 days (range 6 hours to 16.9 years). The proportion of patients not requiring reintervention at 1, 5, and 10 years was 61%, 50%, and 29% in neonates and 83%, 73%, and 44% in older patients, respectively (p = .02); without difference between treatment groups. Larger proportion of patients remained free from valve surgery after optimal BAV result than after adequate or inadequate result (p = .01). The reason for the first reintervention was AS in 50%, AR in 36%, and combined aortic valve disease in 16% of cases. Early mortality (before hospital discharge) was 4.9%, and associated with critical AS in neonates. There was no late mortality during the follow-up. CONCLUSIONS Although majority of congenital AS patients require more than one intervention during childhood, an optimal BAV result improves long-term outcome by increasing the proportion of patients remaining free from valve surgery. High long-term freedom from reintervention is attainable also in the neonatal population.

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.

Abstract
Neonatal aortic valvar stenosis can be challenging to treat because of the varied morphology of the valve, the association with hypoplasia of other left heart structures, and the presence of left ventricular systolic dysfunction or endomyocardial fibroelastosis. Balloon valvuloplasty and surgical valvotomy have been well described in the literature for the treatment of neonatal aortic stenosis. Transcatheter therapy for neonatal aortic stenosis is the preferred method at many centres; however, some centres prefer a surgical approach. Balloon valvuloplasty for neonatal aortic stenosis is reviewed in this manuscript, including the history of the procedure, technical aspects, and acute and long-term outcomes.

Abstract
OBJECTIVES The pulmonary valve (PV) annulus is routinely measured angiographically in PV stenosis prior to balloon dilation. We sought to establish whether this radiation exposure is justified, or whether echocardiographic measurements prior to the procedure are sufficient to guide balloon selection. BACKGROUND Previous studies have found a strong correlation between echocardiographic and angiographic measurements of the PV annulus. However, error of measurement and its implication for procedural practice has not been explored. METHODS A total of 90 procedures in 84 patients were analyzed, at a median age 7.6 months (range 1 day to 14.2 years). The contemporaneous echocardiographic and angiographic measurements were recorded, and the original echocardiograms were re-measured in the 72 available cases by two independent reviewers. RESULTS There was a good correlation between the two measurement methods (R(2) = 0.87). However, the echocardiographic PV measurements were smaller on average, with a significant variation in that discrepancy (mean ratio 0.941 (±0.16)). There was no significant reduction in error if extreme measurements (PV annulus z-score <-3) were excluded (P = 0.09), or if the reviewed echocardiographic measurements were used (P = 0.58). CONCLUSIONS There is an unacceptable discrepancy between the measurement techniques: 95% of patients are predicted to have an echocardiographic measurement error between -37% and +26%. Therefore, there is no correction factor that could be employed to allow safe selection of balloon size, and balloon pulmonary valvoplasty without angiographic PV measurement cannot be advocated.
