Balloon Valvuloplasty in Congenital Critical Aortic Valve Stenosis in Neonates and Infants: A Rescue Procedure for the Left Ventricle.

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.

Long-term results of slide laryngotracheoplasty for congenital subglottic stenosis in newborns and infants

ObjectivesSlide laryngotracheoplasty is an effective, single-step procedure without tracheostomy and stenting for treating high-grade congenital subglottic stenosis in neonates and infants. Long-term outcomes were evaluated to assess the reliability of the procedure performed in this age of rapid development of the laryngeal structures. MethodsWe report five children who underwent slide laryngotracheoplasty before the age of 4 months, each with >3 years follow-up. Increases of length and bodyweight were systematically assessed. Breathing, swallowing, voice, and overall satisfaction was assessed by a quality of life questionnaire. Voice quality was objectively evaluated by measuring shimmer, jitter, fundamental frequency, and the harmonics-to-noise ratio. ResultsAll patients had a stable and adequate airway during follow-up without any additional open airway surgery. The patients' voices were physiological, and the intervention had no negative impact on speech development. Swallowing function was optimally retained, and the patients’ bodyweight gain and length were satisfactory. During at least 3 years of observation, the anastomosis remained stable and grew dynamically with the patient. ConclusionsSlide laryngotracheoplasty (as a single-step procedure) provides an adequate airway without tracheostomy, grafting, or stenting with good long-term functional results in selected neonates and infants with congenital subglottic stenosis.

Current-Era Outcomes of Balloon Aortic Valvotomy in Neonates and Infants

BackgroundThe optimal initial treatment pathway for aortic valve stenosis remains debated. ObjectivesThe objective of this study was to review current outcomes of balloon aortic valvotomy (BAV) in neonates and infants. MethodsNeonates and infants with a biventricular circulation treated with BAV between 2004 and 2019 were reviewed. ResultsOne 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). ConclusionsBAV 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.

Serum N-Terminal Pro-B-Type Natriuretic Peptide as a Biomarker of Critical Pulmonary Stenosis in Neonates.

Objectives: To determine the efficacy of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in predicting critical pulmonary stenosis (CPS) in neonates.Methods: All neonates with pulmonary stenosis (PS) admitted to the neonatal intensive care unit of Xinhua Hospital from October 2014 to December 2020 were retrospectively reviewed. Infants with serum NT-proBNP levels measured within 48 h after birth were enrolled and divided into CPS and non-CPS groups. Serum NT-proBNP levels and cardiac Doppler indices were compared between the two groups. Correlations were determined using the Spearman's rank correlation coefficient. Receiver operator characteristic curve analysis was used to explore the predictive value of NT-proBNP for identifying neonatal CPS.Results: Among 96 infants diagnosed with PS by echocardiography, 46 were enrolled (21 and 25 in the non-CPS and CPS groups, respectively). Serum NT-proBNP levels were significantly higher in the CPS group than in the non-CPS group [3,600 (2,040–8,251) vs. 1,280 (953–2,386) pg/ml, P = 0.003]. Spearman's analysis suggested a positive correlation between Ln(NT-proBNP) levels and the transvalvular pulmonary gradient (r = 0.311, P = 0.038), as well as between Ln(NT-proBNP) levels and pulmonary artery velocity (r = 0.308, P = 0.040). Receiver operating characteristic curve analysis showed that a cutoff serum NT-proBNP level of 2,395 pg/ml yielded a 66.7 and 78.9% sensitivity and specificity for identifying CPS, respectively. The area under the curve was 0.784 (95% CI, 0.637–0.931). A positive correlation was found between Ln(NT-proBNP) and length of hospital stay (r = 0.312, P < 0.05).Conclusion: Serum NT-proBNP level was positively correlated with PS severity and could be used as a biomarker to identify CPS in neonates.

Balloon aortic valvuloplasty in neonates: short- and long-term effects and predictors of successful outcome.

IntroductionBalloon 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.AimTo identify predictors of suboptimal short- and long-term BAV results.Material and methodsThe 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.ResultsThe 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%).ConclusionsBAV 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.

Critical aortic stenosis in neonates: Balloon valvuloplasty versus surgical valvotomy

Congenital aortic valvular stenosis in neonates is a life-threatening condition requiring urgent management. Therapeutic strategy remains controversial between balloon valvuloplasty (BV) and surgical valvulotomy (SV). We reviewed our long-term single-center experience of neonatal aortic stenosis management and compared aortic valve outcomes regarding BV versus SV. Between 1990 and 2020, 137 patients underwent aortic stenosis treatment (SV [ n = 83] and BV [ n = 54]) with a median age of 5.5 days (range: 0 to 30 days) and a median weight of 3 kg (range: 1.8 to 4.8 kg). Procedure strategy was decided according to the surgeon availability especially at the beginning of the study. Additionally, there was a traditional local protocol favoring balloon in case of left ventricular dysfunction like in many centers. The median follow-up was 6.7 years (up to 28y, 88% complete). We did not report any operative death but the intra-hospital mortality was notably greater for patients after balloon procedure (20.3%) versus SV group (8.4%). The one-year and ten-year patient survival was respectively 90 and 89% in SV group versus 75 and 69% in BV group ( P < 0.005). In our cohort, 77 patients underwent reoperation for persistent aortic stenosis. Most of the patients after BV ( n = 38, 70%) required a reintervention. The median age for reintervention was 2.9 years in the SV group versus 0.3 years for patients in the BV group. Associated intracardiac lesions and the initial valvuloplasty procedure were significantly associated with the risk of reoperation independently of the maximal gradient and the aortic annulus size. Ten-year freedom from reintervention for SV and BV group were respectively 53% and 35% ( P < 0.005, Fig. 1 ). Long-term survival and freedom from reintervention are excellent after surgical valvotomy. However, poor results are obtained when patients had initial left ventricular dysfunction or multiple left ventricular outflow lesions.

Laparoscopic diagnosis and treatment of high jejunal atresia and stenosis in neonates

Laparoscopic diagnosis and treatment of high jejunal atresia and stenosis in neonates

The Ross-Konno operation for neonates and infants with severe aortic incompetence following treatment for critical aortic stenosis.

Aortic valve stenosis in neonates and infants is associated with congestive cardiac failure, and balloon or surgical valvuloplasty provides relief of stenosis. Occasionally severe aortic insufficiency necessitates urgent aortic valve replacement. We reviewed our experience with the Ross-Konno procedure in patients <1 year. Between October 2013 and May 2020, 36 patients underwent balloon (34) or surgical (2) aortic valvuloplasty for aortic stenosis. Six patients subsequently underwent a Ross-Konno procedure. The median age at operation was 55 (27-116) days and weight was 4.25 (2.5-12) kg. All patients were in severe cardiac failure and had a small aortic annulus with Z-score -3.1 (-1 to -4.4). There were no early or late deaths. At the latest follow-up at 39 (13-60) months, ventricular function had improved in all patients and no patient was on anti-failure medication. On echocardiography, there wasno more than trivial aortic regurgitation and no left ventricular outflow tract obstruction. One patient required right ventricle to pulmonary artery conduit replacement and one patient had homograft stenting. Despite the severe preoperative haemodynamic compromise, the urgent Ross-Konno procedure was associated with excellent operative survival and recovery of ventricular function. The need for reintervention to the pulmonary conduit remains a cause for concern.

Role of Balloon Aortic Valvuloplasty in the Management of Aortic Stenosis

Balloon aortic valvuloplasty (BAV) provides an excellent alternative to surgical intervention and has become the preferred intervention for initial palliation for aortic stenosis in neonates, infants, children, adolescents, and young adults. The elderly patients with calcific aortic stenosis do not benefit from BAV. With the exception of neonates, most patients can be discharged home within 24-hours of the procedure. Although there is definitive evidence for pressure gradient relief immediately after as well as at follow-up and postponement of surgical intervention following BAV, the progression of aortic insufficiency at late follow up remain a major concern. In the neonatal population, severe aortic insufficiency may develop requiring surgical intervention. Despite these limitations, balloon aortic valvuloplasty is currently considered as therapeutic procedure of choice in the management of congenital aortic stenosis in the pediatric and young adult population. Careful follow-up to detect recurrence of stenosis and development of significant aortic insufficiency is recommended.

Percutaneous Balloon Pulmonary Valvuloplasty of Critical Pulmonary Stenosis and severe pulmonary stenosis in Neonates and Early Infancy: A Challenge in the Cyanotic.

Introduction: Pulmonary stenosis with an intact ventricular septum (PS-IVS) is one of the common causes of cyanotic heart disease in neonates with diverse morphologies as well as management and treatment protocols. The aim of this study was to evaluate short and midterm results of balloon pulmonary valvuloplasty (BPV) for this disorder. Methods: Between 2012 and 2016, Totally 45 neonates and infants under 6 months old were evaluated.The patients had a minimum right-to-left ventricular pressure ratio of 1, right-to-left shunting at the patent foramen ovale or atrial septal defect level, and tricuspid valve Z-scores higher than -4. Results: Immediately after the procedure, the right ventricular pressure dropped to the normal values in 8 (20%) patients. The immediate procedural success rate was seen in 42 (93.3%) cases: the right-to-left ventricular pressure ratio dropped to below 50% or the level of O2 saturation rose above 75%. Of three cases unresponsive to BPV, two of them underwent patent ductus arteriosus (PDA) stenting and one procedural death occurred. At 6 months’ follow-up, of 42 patients, this pressure was still with in the normal range in 36 (80%) infants, while it had returned to high values in 9 (20%) patients and necessitated repeat valvuloplasty. After BPV, severe pulmonary valve regurgitation was observed in14.2% patients; the condition was more common when high-profile noncompliant balloons were used. Conclusion: Balloon pulmonary valvuloplasty in infants with PS-IVS confers acceptable results insofar as it improves echocardiographic parameters and hemodynamic changes at short- and midterm followups.Balloon selection with sizes more than 1.2 of the diameter of the pulmonary valve annulus and the use of noncompliant high-pressure balloons results in higher degrees of pulmonary regurgitation.

Unusual Presentation of Congenital Ileal Stenosis in a Neonate

The presentation of congenital intestinal stenosis in neonates can vary from mild intermittent feeding intolerance resulting in difficulty of clinical judgment to profound obstruction. This report describes one case of ileal stenosis whose radiological investigations were not favoring intestinal obstruction and was diagnosed after surgical exploration.

Abstract 16377: Cardiovascular Computed Tomography Can Predict Branch Pulmonary Artery Stenosis in Neonates With Ductal Dependent Pulmonary Blood Flow

Background: A subpopulation of neonates with ductal dependent pulmonary blood flow (PBF) are at risk for branch pulmonary artery (PA) stenosis in the PA that receives the patent ductus arteriosus (PDA). Identification of this population is important in planning initial and future interventions. The objective of this study was to identify novel cardiovascular computed tomography (CCT) measures in the preoperative period that are associated with the need for future branch PA surgical or catheter-based intervention. Methods: In this single center retrospective study, we identified neonates (&lt; 28 days) with ductal dependent PBF who underwent CCT prior to initial intervention from 11/2003-12/2019. A single reviewer made conventional and novel measurements of the branch PAs as well as PDA size and configuration. The primary outcome was reached if there was any initial or subsequent surgical or catheter-based intervention on the branch PA that received the PDA. Results: A total of 47 neonates (16 female, 31 male) were included. 30 (64%) reached the primary outcome. Upon multivariable regression analysis, PDA origin at the aortic isthmus [OR 7.13 (95% CI 1.01-50.4), p = 0.049] and distance to the largest diameter (DLD) (Figure 1) [OR 1.24 (95% CI 1.01-1.51), p = 0.040] were independently associated with the primary outcome. DLD is the distance of the largest diameter of the PA with the PDA from the bifurcation in confluent PAs or from the insertion of the PDA in discontinuous PAs. On receiver operating characteristic analysis, area under the curve for DLD = 0.75, p = 0.01. A DLD &gt; 6 mm displayed 82% sensitivity and 67% specificity in identifying patients who met the primary outcome. Conclusions: PDA origin at the aortic isthmus and DLD can risk stratify patients at high risk for requiring surgical or catheterization-based branch PA interventions. Further analysis is needed to determine if intervention strategies based on these measurements improve patient outcomes.

Guidelines of the Italian Society of Videosurgery (SIVI) in Infancy for the minimally invasive treatment of Hypertrophic Pyloric Stenosis in neonates and infants.

The most appropriate treatment for the infantile Hypertrophic Pyloric Stenosis (HPS) is still debated. The non-surgical conservative treatment with oral or intravenous administration of atropine does not enjoy a widespread appreciation for several factors (...).

Subglottic Stenosis Position Affects Work of Breathing.

Subglottic stenosis (SGS) is the most common type of laryngeal stenosis in neonates. SGS severity is currently graded based on percent area of obstruction (%AO) via the Myer-Cotton grading scale. However, patients with similar %AO can have widely different clinical courses. Computational fluid dynamics (CFD) based on patient-specific imaging can quantify the relationship between airway geometry and flow dynamics. We investigated the effect of %AO and axial position of SGS on work of breathing (WOB) in neonates using magnetic resonance imaging. High-resolution ultrashort echo-time MRI of the chest and airway was obtained in three neonatal patients with no suspected airway abnormalities; images were segmented to construct three-dimensional (3D) models of the neonatal airways. These models were then modified with virtual SGSs of varying %AO and axial positioning. CFD simulations of peak inspiratory flow were used to calculate patient-specific WOB in nonstenotic and artificially stenosed airway models. CFD simulations demonstrated a relationship between stenosis geometry and WOB increase. WOB rapidly increased with %AO greater than about 70%. Changes in axial position could also increase WOB by approximately the same amount as a 10% increase in %AO. Increased WOB was particularly pronounced when the SGS lumen was misaligned with the glottic jet. The results indicate a strong, predictable relationship between WOB and axial position of the stenotic lumen relative to the glottis, which has not been previously reported. These findings may lead to precision diagnosis and treatment prediction tools in individual patients. 4 Laryngoscope, 131:E1220-E1226, 2021.

A national study of the outcome after treatment of critical aortic stenosis in the neonate.

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. 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. 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%). 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.

Colonic stenosis in neonates is not always congenital or complication of necrotizing enterocolitis

Background: Bowel obstruction in early infancy may results from variety of congenital anomalies involving small and large bowel. Colonic stenosis (CS) congenital or acquired is among the rare causes of chronic bowel obstructions in early infancy. Methods: Medical record of 4 patients with colonic stenosis secondary to Hirschsprung’s disease was reviewed. Results: A total of 4 cases were included in the study. Age of presentation ranged from 25 days to 96 days. Most common presentation was gross abdominal distension with visible bowel loop, vomiting, difficulty in passing stool followed by history of passing recurrent loose stools and failure to thrive. In one case there was suspicion of bowel perforation and was operated in emergency. Initial operative findings and histopathology was not suggestive of Hirschsprung’s Disease, but a full thickness rectal biopsy confirmed HD in all 4 cases. Conclusion: Hirschsprung should be considered as underlying pathology in cases of colonic stricture/stenosis in children.

The Incidence of Laryngotracheal Stenosis in Neonates With a History of Ventilator-Associated Pneumonia.

Neonatal patients requiring prolonged intubation are susceptible to both infection and laryngotracheal stenosis (LTS). This study investigated the effect of ventilator-associated pneumonia (VAP) on the development of LTS in neonates. Retrospective case-control study. The incidence of LTS in neonates with VAP was compared with the incidence of LTS in matched intubated controls without VAP. Patients were treated at a tertiary-care medical center from 2004 to 2014. Eligible patient records were assessed for the development of LTS. Demographics, medical comorbidities, infection characteristics, and treatment variables were compared using unpaired t test or χ2 test. Statistical significance was set a priori at P < .05. When comparing the VAP patients with matched non-VAP controls, we found no significant differences in the incidence of LTS (VAP vs. non-VAP, 8.3% vs. 6.7%; P = .73). In subgroup analysis of the VAP cohort, LTS and non-LTS patients demonstrated similar VAP organisms on broncho-alveolar lavage (Klebsiella pneumoniae, Pseudomonas aeroginosa, Escherichia coli, methicillin-resistant Staphylococcus aureus, Streptococcus pneumoniae, and Enterobacter). Additionally, within the VAP cohort, LTS and non-LTS patients showed similar gestational age (LTS vs. non-LTS, 31.3 days vs. 28.1 days; P = .22), birth weight (LTS vs. non-LTS, 1.6 kg vs. 1.2 kg; P = .33), and similar intubation duration (LTS vs. non-LTS, 37.8 days vs. 27.5 days; P = .52). In this neonatal cohort, VAP was not associated with an increased incidence of LTS. Given severity of the burden of LTS on the healthcare system, multi-institutional longitudinal investigation into contributing risk factors for neonatal LTS is warranted.

Simultaneous Repair of Pulmonary Artery Sling and Tracheal Stenosis in Neonate

Simultaneous Repair of Pulmonary Artery Sling and Tracheal Stenosis in Neonate

Assessment of meatal stenosis in neonates undergoing circumcision using Plastibell Device with two different techniques

PurposeIt was intended to compare meatal stenosis (MS) as a late complication of neonatal circumcision by using two different methods of Plastibell Device circumcision.Materials and methodsA total of 2,307 healthy term newborns (6–36 hours) who were born between 2007 and 2009 in Niknafs Medical Center of Rafsanjan, Iran, were simply randomized into two groups in a controlled, nonblinded clinical trial. In group A (1,102 neonates), the frenulum was maintained intact without any manipulation, and in group B (1,205 neonates) frenular hemostasis was performed in all cases by thermal cautery. MS was assessed by follow-up visits that were made for all cases at the 24–72 hours, 60th day, 12th month, and 16th month after circumcision.ResultsAt 2 months follow-up visit, the rate of MS in group A was 4.9% (54) and in group B was 5.9% (71), which was not statistically significant. After 12 months, MS in group A was 8.5% (94) and in group B was 13.7% (165), which was statistically significant (P<0.001). At 16 months after circumcision, in the frenulum intact group, MS was 13.8% (152) and in the cautery group, it was 18.9% (228), which was compatible with significant difference (P=0.001).ConclusionOur experience with large group of cases revealed that neonatal circumcision by using Plastibell Device with intact frenulum technique decreases the rate of delayed MS.

Bronchial Mismatch as a Predictor of Respiratory Failure After Congenital Tracheal Stenosis Repair

The purpose of this study was to identify predictors of postoperative respiratory failure after surgical tracheoplasty for congenital tracheal stenosis. Between February 2011 and April 2017, 16 infants underwent congenital tracheal stenosis repair. Preoperative computed tomography evaluation of the trachea and mainstem bronchi was performed. The primary outcome was midterm freedom from postoperative respiratory failure defined as persistent need for mechanical ventilation or surgical tracheobronchial reoperation. Bronchial mismatch, defined as [1- (smaller bronchus diameter / larger bronchus diameter)]× 100, was analyzed in relation to the primary outcome. Median age was 106 days (range, 1 to 406) and median weight was 5.3 kg (range, 2.6 to 8 kg). Four patients were neonates (25%) and 6 had genetic abnormalities (37.5%). There were no early nor late deaths. Median ventilation time was 5.5 days (range, 3 to 45). Mean follow-up time was 2.2 years (range, 0.1 to 4.5). Four patients with bronchial mismatch greater than 20% had postoperative respiratory failure (p= 0.002). Two of them underwent tracheostomy and were discharged with ventilation home care support. One underwent successful reoperation consisting of bilateral bronchial plasty with autologous cartilage rib grafts, and the other underwent successful right bronchial and tracheal reconstruction. One patient with bilateral bronchial hypoplasia underwent slide tracheoplasty associated with preemptive bilateral bronchial plasty and made a full recovery. Surgical treatment of congenital tracheal stenosis in neonates and infants portends a good outcome. Bronchial mismatch greater than 20% can identify a subset of patients at increased risk for surgical reintervention and chronic respiratory failure. Slide tracheoplasty with preemptive bronchial reconstruction may prevent postoperative respiratory failure.
