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.

Sperotto F, Gearhart A, Hoskote A, Alexander PMA, Barreto JA, Habet V, Valencia E, Thiagarajan RR. Cardiac arrest and cardiopulmonary resuscitation in pediatric patients with cardiac disease: a narrative review. Eur J Pediatr 2023; 182:4289-4308. [PMID: 37336847 PMCID: PMC10909121 DOI: 10.1007/s00431-023-05055-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 05/27/2023] [Accepted: 06/02/2023] [Indexed: 06/21/2023]
Abstract
Children with cardiac disease are at a higher risk of cardiac arrest as compared to healthy children. Delivering adequate cardiopulmonary resuscitation (CPR) can be challenging due to anatomic characteristics, risk profiles, and physiologies. We aimed to review the physiological aspects of resuscitation in different cardiac physiologies, summarize the current recommendations, provide un update of current literature, and highlight knowledge gaps to guide research efforts. We specifically reviewed current knowledge on resuscitation strategies for high-risk categories of patients including patients with single-ventricle physiology, right-sided lesions, right ventricle restrictive physiology, left-sided lesions, myocarditis, cardiomyopathy, pulmonary arterial hypertension, and arrhythmias. Cardiac arrest occurs in about 1% of hospitalized children with cardiac disease, and in 5% of those admitted to an intensive care unit. Mortality after cardiac arrest in this population remains high, ranging from 30 to 65%. The neurologic outcome varies widely among studies, with a favorable neurologic outcome at discharge observed in 64%-95% of the survivors. Risk factors for cardiac arrest and associated mortality include younger age, lower weight, prematurity, genetic syndrome, single-ventricle physiology, arrhythmias, pulmonary arterial hypertension, comorbidities, mechanical ventilation preceding cardiac arrest, surgical complexity, higher vasoactive-inotropic score, and factors related to resources and institutional characteristics. Recent data suggest that Extracorporeal membrane oxygenation CPR (ECPR) may be a valid strategy in centers with expertise. Overall, knowledge on resuscitation strategies based on physiology remains limited, with a crucial need for further research in this field. Collaborative and interprofessional studies are highly needed to improve care and outcomes for this high-risk population. What is Known: • Children with cardiac disease are at high risk of cardiac arrest, and cardiopulmonary resuscitation may be challenging due to unique characteristics and different physiologies. • Mortality after cardiac arrest remains high and neurologic outcomes suboptimal. What is New: • We reviewed the unique resuscitation challenges, current knowledge, and recommendations for different cardiac physiologies. • We highlighted knowledge gaps to guide research efforts aimed to improve care and outcomes in this high-risk population.

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
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 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
Cardiac arrest occurs at a higher rate in children with heart disease than in healthy children. Pediatric basic life support and advanced life support guidelines focus on delivering high-quality resuscitation in children with normal hearts. The complexity and variability in pediatric heart disease pose unique challenges during resuscitation. A writing group appointed by the American Heart Association reviewed the literature addressing resuscitation in children with heart disease. MEDLINE and Google Scholar databases were searched from 1966 to 2015, cross-referencing pediatric heart disease with pertinent resuscitation search terms. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. The recommendations in this statement concur with the critical components of the 2015 American Heart Association pediatric basic life support and pediatric advanced life support guidelines and are meant to serve as a resuscitation supplement. This statement is meant for caregivers of children with heart disease in the prehospital and in-hospital settings. Understanding the anatomy and physiology of the high-risk pediatric cardiac population will promote early recognition and treatment of decompensation to prevent cardiac arrest, increase survival from cardiac arrest by providing high-quality resuscitations, and improve outcomes with postresuscitation care.

Abstract
OBJECTIVE Shone's syndrome is a complex consisting of mitral valve stenosis in addition to left ventricle outflow obstruction. There are a few studies evaluating the long-term outcomes in this population. We sought to determine the long-term outcomes in our paediatric population with Shone's syndrome and the factors associated with left heart growth. METHODS All patients diagnosed with Shone's syndrome with biventricular circulation treated between 1978 and 2010 were reviewed. Baseline echocardiograms and data from catheterisations were also reviewed. Number of interventions (surgical+transcatheter), incidence of mitral valve replacement, and incidence of heart transplantation were tracked. Survival of the population and left heart structural growth were also reviewed. RESULTS A total of 121 patients with Shone's syndrome presented at a median age of 28 days (0-17.3 years) and were followed-up for 7.2 years (0.01-35.5 years). These patients underwent 258 interventions during the study period, and the presence of coarctation was associated with repeat left heart interventions. The 10-year, transplant-free survival was 86%. Presence of pulmonary hypertension was associated with mortality. Left heart structural growth was seen for mitral and aortic valve annuli and left ventricular end-diastolic dimension over time. CONCLUSIONS Shone's syndrome patients undergo a number of left heart interventions. Coarctation of the aorta is associated with an increased likelihood for repeat interventions. Survival appears to be more favourable than expected. Significant left heart growth will occur in the population. Pulmonary hypertension is associated with an increased risk of mortality.

Abstract
Aortic valve morphology has been invoked as intrinsic to outcomes of balloon aortic valvuloplasty (BAV) for congenital aortic valve stenosis. We sought to use aortic valve morphologic features to discriminate between valves that respond favorably or unfavorably to BAV, using aortic insufficiency (AI) as the primary outcome. All patients who underwent BAV at 2 large-volume pediatric centers from 2007 to 2014 were reviewed. Morphologic features assessed on pre-BAV echo included valve pattern (unicuspid, functional bicuspid, and true bicuspid), leaflet fusion length, leaflet excursion angle, and aortic valve opening area and on post-BAV echo included leaflet versus commissural tear. Primary end point was increase in AI (AI+) of ≥2°. Eighty-nine patients (median age 0.2 years) were included in the study (39 unicuspid, 41 functional bicuspid, and 9 true bicuspid valves). Unicuspid valves had a lower opening area (p <0.01) and greater fusion length (p = 0.01) compared with functional and true bicuspid valves. Valve gradient pre-BAV and post-BAV were not different among valve patterns. Of the 16 patients (18%) with AI+, 14 had leaflet tears (odds ratio 13.9, 3.8 to 50). True bicuspid valves had the highest rate (33%) of AI+. On multivariate analysis, leaflet tears were associated with AI+, with larger opening area pre-BAV and lower fusion length pre-BAV. AI+ was associated with larger pre-BAV opening area. Gradient relief was associated with reduced angle of excursion. Valve morphology influences outcomes after BAV. Valves with lesser fusion and larger valve openings have higher rates of leaflet tears which in turn are associated with AI.

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
Aortic stenosis is a congenital or acquired reduction in the area of the aortic valve, resulting in obstruction of the blood flow from the left ventricle to the aorta. Aortic stenosis accounts for 2-5% of all congenital heart defects and is a potentially life-threatening disorder. In adults aortic stenosis represents 34% of all valvular heart diseases. Degenerative etiology is present in 80% of cases. Patients with mild aortic stenosis are usually asymptomatic. Symptoms of the disease occur along with the disappearance of effective compensatory mechanisms. These are symptoms of low cardiac output syndrome manifested as fainting, dizziness, ischemic pains, exercise intolerance, arrhythmias with the risk of sudden cardiac death, and heart failure. As soon as the symptoms occur the prognosis significantly worsens, which is associated with a high risk of death. Percutaneous aortic valvuloplasty is a palliative method of treatment of aortic stenosis. The aim of the procedure is to relieve left ventricular outflow tract obstruction, thereby improving cardiac output. The etiology, course of the aortic stenosis and treatment methods, including invasive procedures, vary depending on the patients' age. The purpose of this paper is to present the characteristics of the aortic valve disease and the strategy of aortic balloon valvuloplasty in different age groups.
