Abstract
OBJECTIVES Extubation failure is associated with morbidity and mortality in children following cardiac surgery. Current extubation readiness tests (ERT) do not consider the nonrespiratory support provided by mechanical ventilation (MV) for children with congenital heart disease. We aimed to identify factors associated with extubation failure in children following cardiac surgery and assess the performance of two risk analytics algorithms for patients undergoing an ERT. DESIGN Retrospective cohort study. SETTING CICU at a tertiary-care children's hospital. PATIENTS Children receiving MV greater than 48 hours following cardiac surgery between January 1, 2017, and December 31, 2019. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Six hundred fifty encounters were analyzed with 49 occurrences (8%) of reintubation. Extubation failure occurred most frequently within 6 hours of extubation. On multivariable analysis, younger age (per each 3-mo decrease: odds ratio [OR], 1.06; 95% CI, 1.001-1.12), male sex (OR, 2.02; 95% CI, 1.03-3.97), Society of Thoracic Surgery-European Association for Cardiothoracic Surgery category 5 procedure (p equals to 0.005), and preoperative respiratory support (OR, 2.08; 95% CI, 1.09-3.95) were independently associated with unplanned reintubation. Our institutional ERT had low sensitivity to identify patients at risk for reintubation (23.8%; 95% CI, 9.7-47.6%). The addition of the inadequate delivery of oxygen (IDO2) index to the ERT increased the sensitivity by 19.0% (95% CI, -2.5 to 40.7%; p = 0.05), but the sensitivity remained low and the accuracy of the test dropped by 8.9% (95% CI, 4.7-13.1%; p < 0.01). CONCLUSIONS Preoperative respiratory support, younger age, and more complex operations are associated with postoperative extubation failure. IDO2 and IVCO2 provide unique cardiorespiratory monitoring parameters during ERTs but require further investigation before being used in clinical evaluation for extubation failure.

Contemporary outcomes of the double switch operation for congenitally corrected transposition of the great arteries. J Thorac Cardiovasc Surg 2022; 164:1980-1990.e7. [PMID: 35688715 DOI: 10.1016/j.jtcvs.2022.01.049] [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: 07/15/2020] [Revised: 09/24/2021] [Accepted: 01/10/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVE To determine the contemporary outcomes of the double switch operation (DSO) (ie, Mustard or Senning + arterial switch). METHODS A single-institution, retrospective review of all patients with congenitally corrected transposition of the great arteries undergoing a DSO. RESULTS Between 1999 and 2019, 103 patients underwent DSO with a Mustard (n = 93) or Senning (n = 10) procedure. Segmental anatomy was (S, L, L) in 93 patients and (I, D, D) in 6 patients. Eight patients had heterotaxy and 71 patients had a ventricular septal defect. Median age was 2.1 years (range, 1.8 months-40 years), including 34 patients younger than age 1 year (33%). Median weight was 10.9 kg (range, 3.4-64 kg). Sixty-one patients had prior pulmonary artery bands for a median of 1.1 years (range, 14 days-12.9 years; interquartile range, 0.7-3.1 years). Median intensive care unit and hospital lengths of stay were 5 and 10 days, respectively. Median follow-up was 3.4 years (interquartile range, 1-9.8 years) and 5.2 years (interquartile range, 2.3-10.7 years) in 79 patients with >1 year follow-up. At latest follow-up, aortic, mitral, tricuspid valve regurgitation, and left ventricle dysfunction was less than moderate in 96%, 98%, 96%, and 93%, respectively. Seventeen patients underwent reoperation: neoaortic valve intervention (n = 10), baffle revision (n = 5), and ventricular septal defect closure (n = 4). At latest follow-up, 17 patients (17%) had a pacemaker and 27 (26%) had cardiac resynchronization therapy devices. There were 2 deaths and 2 transplants. Transplant-free survival was 94.6% at 5 years. Risk factors for death or transplant included longer cardiopulmonary bypass time and older age at DSO. CONCLUSIONS The outcomes of the DSO are promising. Earlier age at operation might favor better outcomes. Progressive neoaortic regurgitation and reinterventions on the neo-aortic valve are anticipated problems.

Abstract
BACKGROUND Risk stratification in patients with repaired tetralogy of Fallot (rTOF) have focused on poor clinical outcomes while predictors of a benign clinical course have not been characterized. OBJECTIVE The goal of this study was to Identify cardiac magnetic resonance (CMR) markers of a good clinical course late after TOF repair. METHODS Clinical and CMR data from the International Multicenter TOF Registry (INDICATOR) were analyzed. The primary outcome was time to the earliest occurrence of a composite of death, aborted sudden death, and sustained ventricular tachycardia (VT). The secondary outcome was time to the earliest occurrence of atrial arrhythmia, nonsustained VT, and NYHA class >II. Multinomial regression was used to identify predictors of the 3-category outcome: (a) good outcome, defined as freedom from the primary AND secondary outcomes at age 50 years; (b) poor outcome, defined as presence of the primary outcome before age 50 years; and (c) intermediate outcome, defined as not fulfilling criteria for good or poor outcomes. RESULTS Among 1088 eligible patients, 96 had good outcome, 60 experienced poor outcome, and 932 had intermediate outcome. Patients were age 25.8±10.8 years at the time of the index CMR. Median follow-up was 5.8 years (IQR 3.0, 9.9) after CMR in event-free patients. By univariate analysis, smaller right ventricular (RV) end-systolic and end-diastolic volume index, smaller left ventricular end-systolic volume index, higher right and left ventricular ejection fraction, lower right and left ventricular mass index, and lower left ventricular mass/volume ratio were associated with good outcome. Multivariable modeling identified higher RV ejection fraction (OR 2.38 per 10% increase, P = .002) and lower RV mass index (OR 1.72, per 10 g/m2 decrease, P = .002) as independently associated with good outcome after adjusting for age at CMR. Classification and regression tree analysis identified important thresholds associated with good outcome that were specific to patients age ≥37 years at the time of CMR; these were RV ejection fraction ≥42% and RV mass index <39 g/m2. CONCLUSIONS Adults with rTOF and no more than mild RV dysfunction combined with no significant RV hypertrophy are likely to be free from serious adverse clinical events into their sixth decade of life and may require less frequent cardiac testing.

Abstract
We describe waiting times for pediatric heart transplant (HT) candidates after the 2016 revision to the US allocation policy. The OPTN database was queried for pediatric HT candidates listed between 7/2016 and 4/2019. Of the 1789 included candidates, 65% underwent HT, 14% died/deteriorated, 8% were removed for improvement, and 13% were still waiting at the end of follow-up. Most candidates were status 1A at HT (81%). Median wait times differ substantially by listing status, blood type, and recipient weight. The likelihood of HT was lower in candidates <25 kg and in those with blood type O; The <25 kg, blood type O subgroup experiences longer wait times and higher wait list mortality. For status 1A candidates, median wait times were 108 days (≤25 kg, blood type O), 80 days (≤25 kg, non-O), 47 days (>25 kg, O), and 24 days (>25 kg, non-O). We found that centers with more selective organ acceptance practices, based on a lower median Pediatric Heart Donor Assessment Tool (PH-DAT) score for completed transplants, experience longer status 1A wait times for their listed patients. These data can be used to counsel families and to select appropriate advanced heart failure therapies to support patients to transplant.

Abstract
Background: Biomarkers are increasingly part of assessing and managing heart failure (HF) in adults with congenital heart disease (CHD). Objectives: To understand the response of cardiac biomarkers with therapy for acute decompensated heart failure (ADHF) and the relationship to prognosis after discharge in adults with CHD. Design: A prospective, observational cohort study with serial blood biomarker measurements. Settings: Single-center study in the inpatient setting with outpatient follow-up. Participants: Adults (≥18 years old) with CHD admitted with ADHF between August 1, 2019, and March 1, 2020. Exposure: We measured body mass, Kansas City Cardiomyopathy Questionnaire (KCCQ-12) score, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and high-sensitivity C-reactive protein (hsCRP) at enrollment, discharge, and 1st clinic follow-up visit; soluble suppression of tumorigenicity 2 (sST2) was measured at the first two time points. Measures: Univariate regression assessed the association between changes in weight, biomarkers, and changes in KCCQ-12 scores, between enrollment and discharge (ΔHospitalization) and between discharge and 1st clinical follow-up visit (ΔPost−discharge). Wilcoxon rank-sum tests assessed the association between change in biomarkers, KCCQ-12 scores, and the composite outcome of cardiovascular death or rehospitalization for ADHF. Results: A total of 26 patients were enrolled. The median age was 51.9 years [IQR: 38.8, 61.2], 13 (54.2%) were women, and median hospital stay was 6.5 days [IQR: 4.0, 15.0] with an associated weight loss of 2.8 kg [IQR −5.1, −1.7]. All three cardiac biomarkers decreased during hospitalization with diuresis while KCCQ-12 scores improved; a greater decrease in sST2 was associated with an improved KCCQ-12 symptom frequency (SF) subdomain score (p = 0.012), but otherwise, there was no significant relationship between biomarkers and KCCQ-12 change. Change in hsCRP and NT-proBNP after discharge was not associated with the composite outcome (n = 8, vs. n = 16 who did not experience the outcome; Δ Post-discharge hsCRP +5.1 vs. −1.0 mg/l, p = 0.061; NT-proBNP +785.0 vs. +130.0 pg/ml, p = 0.220). Conclusions: Serial biomarker measurements respond to acute diuresis in adults with CHD hospitalized for ADHF. These results should motivate further research into the use of biomarkers to inform HF therapy in adults with CHD.

Abstract
OBJECTIVES Critically ill patients receiving renal replacement therapy (RRT) in the pediatric cardiac intensive care unit (CICU) are at high risk for inadequate nutrition delivery. The objective of this study is to evaluate barriers to adequate energy and protein delivery in critically ill patients with congenital heart disease receiving RRT. METHODS This is a single-center retrospective cohort study of patients receiving RRT in the CICU from 2011 to 2019. Energy and protein adequacy was recorded over the first 7 days of RRT. Adequacy was defined as delivery of >80% of the energy and protein targets during this time period. Patients who achieved adequacy were compared to those who did not. Multivariable logistic regression models were constructed to determine factors independently associated with energy and protein adequacy while receiving RRT. RESULTS Sixty patients were included for analysis. Fifty-five patients (92%) achieved energy adequacy and 37 patients (62%) achieved protein adequacy. A higher weight-for-age z-score (WAZ) on admission to the CICU was the only independent predictor of inadequate energy intake (odds ratio 0.07, 95% confidence interval 0.01-0.58, P = .014); median WAZ was -1.17 versus +1.24 for those with adequate versus inadequate energy intake, respectively. Fluid restriction to <80% of maintenance fluid at the time of RRT initiation was more likely in patients with higher WAZ. Fluid restriction was the only independent predictor of inadequate protein intake (odds ratio 0.13, 95% confidence interval 0.02-0.7, P = .018); 5% versus 30% were fluid restricted in those with adequate versus inadequate protein intake, respectively. Azotemia was not associated with inadequate protein intake. Initiation of RRT did not allow for liberalization of fluid intake over the time period evaluated. CONCLUSIONS Protein delivery was inadequate in 38% of children undergoing RRT in the CICU. Fluid restriction was associated with inadequate protein intake and higher WAZ was associated with inadequate energy intake.

Abstract
Sudden infant death syndrome (SIDS) is understood as a syndrome that presents with the common phenotype of sudden death but involves heterogenous biological causes. Many pathological findings have been consistently reported in SIDS, notably in areas of the brain known to play a role in autonomic control and arousal. Our laboratory has reported abnormalities in SIDS cases in medullary serotonin (5-HT) receptor 1A and within the dentate gyrus of the hippocampus. Unknown, however, is whether the medullary and hippocampal abnormalities coexist in the same SIDS cases, supporting a biological relationship of one abnormality with the other. In this study, we begin with an analysis of medullary 5-HT1A binding, as determined by receptor ligand autoradiography, in a combined cohort of published and unpublished SIDS (n = 86) and control (n = 22) cases. We report 5-HT1A binding abnormalities consistent with previously reported data, including lower age-adjusted mean binding in SIDS and age vs. diagnosis interactions. Utilizing this combined cohort of cases, we identified 41 SIDS cases with overlapping medullary 5-HT1A binding data and hippocampal assessment and statistically addressed the relationship between abnormalities at each site. Within this SIDS analytic cohort, we defined abnormal (low) medullary 5-HT1A binding as within the lowest quartile of binding adjusted for age and we examined three specific hippocampal findings previously identified as significantly more prevalent in SIDS compared to controls (granular cell bilamination, clusters of immature cells in the subgranular layer, and single ectopic cells in the molecular layer of the dentate gyrus). Our data did not find a strong statistical relationship between low medullary 5-HT1A binding and the presence of any of the hippocampal abnormalities examined. It did, however, identify a subset of SIDS (~25%) with both low medullary 5-HT1A binding and hippocampal abnormalities. The subset of SIDS cases with both low medullary 5-HT1A binding and single ectopic cells in the molecular layer was associated with prenatal smoking (p = 0.02), suggesting a role for the exposure in development of the two abnormalities. Overall, our data present novel information on the relationship between neuropathogical abnormalities in SIDS and support the heterogenous nature and overall complexity of SIDS pathogenesis.

Abstract
OBJECTIVE To characterize parent-reported symptom burden and effectiveness of symptom management in children hospitalized with advanced heart disease. STUDY DESIGN Prospective survey study of 161 parents whose child was admitted to a single institution with advanced heart disease between March 2018 and February 2019 using the Survey about Caring for Children with Heart Disease. RESULTS Of the 161 patients, 54% were under 2 years old with a diagnosis of single ventricle physiology (39%), pulmonary hypertension (12%), and other congenital heart disease (28%). Over one-half (56%) of parents reported that their child was experiencing a high degree ("a great deal"/"a lot") of symptoms. The most frequently reported symptoms were pain (68%), fatigue (63%), and breathing difficulties (60%). Of the symptoms that were treated, parents perceived successful treatment to be least likely for their child's sleep disturbance (24%), depression (29%), and fatigue (35%). Parents who reported their child's functional status as New York Heart Association class III/IV were more likely to report that their child was experiencing "a great deal" of symptoms, compared with those who reported class I/II (51% vs 19%, P < .001). Parents who reported their child was experiencing a high degree of suffering from fatigue were also more likely to report a high symptom burden (P < .001). CONCLUSIONS Parents of children with advanced heart disease reported high symptom burden with a broad spectrum of symptoms. Parents reported fatigue and psychiatric symptoms frequently and rarely reported treatment as successful. Parents' view of their child's symptom burden was concordant with their perception of their child's functional status.

Abstract
Evaluate outcomes of single leaflet aortic valve reconstruction using Ozaki sizer and template. Single institute retrospective analysis between August 2015 and August 2019. Thirty-three patients, median age 9.3 years and weight 29.2 kg underwent single leaflet Ozaki repair. Preoperative indications were: AR (n = 17), AS (n = 3) or AS/AR (n = 13). Baseline anatomy was unicuspid (n = 15), bicuspid (n = 9) or tricuspid (n = 9). Two patients had endocarditis. Prior interventions included balloon valvuloplasty (n = 22) and aortic valve repair (n = 9). Pre-op average native annulus diameter was 19.6 mm and peak echo gradient was 36 mm Hg. Autologous pericardium, Photofix and CardioCel bovine pericardium were used in 26, 5, and 2 patients. Non-coronary sinus enlargement was required in 3 and aortic root reduction in 9 patients. Single leaflet reconstruction was done for the right coronary cusp (n = 25), non-coronary cusp in (n = 6) and left coronary cusp (n = 2). Additional procedures were done in 30 patients. Median ICU and hospital LOS were 2.1 and 6.3 days. There were no early re-interventions or conversions to valve replacement and one unrelated mortality.en At discharge, all patients had < moderate AR and/or AS with average peak gradients of 15 mm Hg. The median follow-up was 1.1 year, (IQR 0.7-1.8 years). Freedom from ≥ moderate AR and AS at 2 years was 76% and 86%. One patient required surgical re-intervention for severe AR 1.5 years after surgery for inflammatory infiltrate with calcification and fibrosis. Single-leaflet aortic valve leaflet reconstruction utilizing the Ozaki technique has promising early results and can be considered in patients when there are acceptable native leaflets.

Abstract
BACKGROUND The benefits of a comprehensive enhanced recovery after surgery (ERAS®) program for the congenital heart disease population are largely unknown. We evaluated adherence and outcomes following a recently implemented enhanced recovery program (ERP) in congenital cardiac surgery. METHODS Patients undergoing elective surgery for simple and moderately complex congenital cardiac surgery followed institutional ERP guidelines since 10/2018. Adherence to guidelines over a 12-month period (P2) was compared to implementation data (P1:5 months). The association of outcomes with continuous time was estimated using linear regression. RESULTS Among 559 patients (representing 40% of the cardiac surgical volume) following the ERP over a period of 17 months, no differences in patient characteristics were observed between periods, except higher incidence of prior operations in P2. Adherence to many aspects of guidelines improved from P1 to P2. Notably, operating room extubation: 27% in P2 vs.16% in P1, p=0.006; decrease in median ventilation time: 6.0-hrs (IQR 0-9.2) in P2 vs. 7.6-hrs (IQR 3.8-12.3) in P1, p=0.002. In addition, there was a reduction in opioids, reported as oral morphine equivalents (OME), most significant for intraoperative OME: 5.00 mg/kg (3.11-7.60) in P2 vs. 6.05 mg/kg (3.77-9.78) in P1, p=0.001. There was no difference in overall intensive care unit (ICU) and postoperative length of stay except in lower risk surgeries. Surgical outcomes were similar in the two periods. CONCLUSIONS An enhanced recovery program reduced the use of opioids, led to more OR extubation and reduced mechanical ventilation duration in patients undergoing congenital cardiac surgery.

Abstract
INTRODUCTION Cardiac magnetic resonance (CMR) derived biventricular global function index (BVGFI) is a new CMR parameter that integrates biventricular volumes, mass, and function using clinically available CMR parameters. The associations of BVGFI with clinical outcomes in repaired tetralogy of Fallot are unknown. METHODS Patients with repaired tetralogy of Fallot who had a CMR before the occurrence of a composite outcome of death, resuscitated sudden death, or sustained ventricular tachycardia were studied. BVGFI was calculated as the average of right and left GFI. GFI was defined as (ventricular stroke volume×100)/(ventricular mean cavity volume + total ventricular myocardial volume). Ventricular mean cavity volume was defined as ([end-diastolic + end-systolic volume]/2). Cox multivariable regression analysis and classification and regression tree methodology were used. RESULTS Of the 736 eligible subjects (mean age at CMR 25.4±14.5 years), with a median follow-up of 28 months, 55 subjects (7.4%) reached the composite outcome (46 deaths and 9 sustained ventricular tachycardia). Independent associations with the composite outcome were as follows: BVGFI <37 (hazard ratio, 2.52; P=0.004), right ventricular end-systolic volume index >85 mL/m2 (hazard ratio, 3.25; P<0.001), atrial tachycardia (hazard ratio, 2.03; P=0.021), and age at repair >2.5 years (hazard ratio, 3.37; P<0.001). Classification and regression tree analysis identified BVGFI as the most discriminatory CMR parameter associated with a high risk for adverse outcomes. CONCLUSIONS BVGFI, a novel CMR-derived imaging biomarker combining biventricular volumes, mass, and function, may improve risk stratification for adverse clinical outcomes in patients with repaired tetralogy of Fallot.

Accuracy of Cardiac Magnetic Resonance Imaging Diagnosis of Pediatric Cardiac Masses: A Multicenter Study. JACC Cardiovasc Imaging 2021; 15:1391-1405. [PMID: 34419404 DOI: 10.1016/j.jcmg.2021.07.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 06/21/2021] [Accepted: 07/06/2021] [Indexed: 11/17/2022]
Abstract
OBJECTIVES The goals of this study were to: 1) evaluate the cardiac magnetic resonance (CMR) characteristics of pediatric cardiac masses from a large international cohort; 2) test the accuracy of previously developed CMR-based diagnostic criteria; and 3) expand diagnostic criteria using new information. BACKGROUND After diagnosis of a cardiac mass, clinicians must weigh the benefits and risks of ascertaining a tissue diagnosis. Limited data are available on the accuracy of previously developed noninvasive pediatric CMR-based diagnostic criteria. METHODS CMR studies (children 0-18 years of age) with confirmatory histological and/or genetic diagnosis were analyzed by 2 reviewers, without knowledge of prior diagnosis. Diagnostic accuracy was graded as: 1) single correct diagnosis; 2) correct diagnosis among a differential; or 3) incorrect diagnosis. RESULTS Of 213 cases, 174 (82%) had diagnoses that were represented in the previously published diagnostic criteria. In 70% of 174 cases, both reviewers achieved a single correct diagnosis (94% of fibromas, 71% of rhabdomyomas, and 50% of myxomas). When ≤2 differential diagnoses were included, both reviewers reached a correct diagnosis in 86% of cases. Of 29 malignant tumors, both reviewers indicated malignancy as a single diagnosis in 52% of cases. Including ≤2 differential diagnoses, both reviewers indicated malignancy in 83% of cases. Of 6 CMR sequences examined, acquisition of first-pass perfusion and late gadolinium enhancement were independently associated with a higher likelihood of a single correct diagnosis. CONCLUSIONS CMR of cardiac masses in children leads to an accurate diagnosis in most cases. A comprehensive imaging protocol is associated with higher diagnostic accuracy.

Normal Left Ventricular Systolic and Diastolic Strain Rate Values in Children Derived from Two-Dimensional Speckle-Tracking Echocardiography. J Am Soc Echocardiogr 2021; 34:1303-1315.e3. [PMID: 34325008 DOI: 10.1016/j.echo.2021.07.013] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 07/19/2021] [Accepted: 07/19/2021] [Indexed: 01/28/2023]
Abstract
BACKGROUND Strain rate (SR) parameters derived from two-dimensional speckle-tracking echocardiography have prognostic value in children with heart disease. Routine use is hindered by a lack of normative data. The aim of this study was to determine reference values and Z scores for left ventricular systolic and diastolic SR in a large cohort of healthy children. METHODS Echocardiograms from 577 subjects ≤18 years of age (mean age, 9.6 ± 5.6 years; range, 1 day to 18.0 years; 46% female) with structurally and functionally normal hearts were retrospectively included. Left ventricular longitudinal and circumferential systolic and early and late diastolic SR were measured using two-dimensional speckle-tracking echocardiography from the apical four-chamber and short-axis mid-papillary views. Associations with age and body surface area were assessed using Spearman correlation and generalized additive modeling. The relationship between systolic SR and wall stress (afterload) was examined. Analyses were conducted with and without correction for heart rate. Multivariable linear regression modeling was used to identify independent factors associated with the SR parameters. Z score equations were derived from a selected best-fit parametric model. RESULTS All SR parameters differed significantly by age group. The magnitude of all SR values decreased with increasing age and body surface area. Systolic SR magnitude was inversely related to wall stress in children ≤7 years of age but not did not vary significantly in the older age groups. All relationships were maintained after heart rate correction. SR measurements had very good or excellent agreement. CONCLUSION Longitudinal and circumferential systolic and diastolic SR parameters are presented from a large cohort of healthy children using two-dimensional speckle-tracking echocardiography from the Philips platform. SR values differ significantly by age and body surface area. These results suggest that the myocardium becomes less sensitive to afterload with maturity. Z score equations based on age are presented, which should promote further clinical and research use.

Abstract
Bioprosthetic aortic valve replacement (bAVR) in patients with congenital heart disease is challenging due to age, size and complexity. Our objective was to assess survival and identify predictors of re-operation. Data were retrospectively collected for 314 patients undergoing bAVR at 8 centers from 2000-2014. Kaplan-Meier estimation of time to re-operation and Cox regression were utilized. Average age was 45.2 years (IQR 17.8-71.1) and 30% were <21. Indications were stenosis (48%), regurgitation (28%) and mixed (18%). Twenty-eight (9%) underwent prior AVR. Median valve size was 23mm (IQR 21, 25). Implanted valves included CE (Carpentier-Edwards) Perimount (47%), CE Magna/Magna Ease (29%), Sorin Mitroflow (9%), St Jude (2%) and other (13%). Median follow-up was 2.9 (IQR 1.2, 5.7) years. Overall, 11% required re-operation, 35% of whom had a Mitroflow and 65% were <21 years old. Time to re-operation varied among valve type (p=0.020). Crude 3-year rate was 20% in patients ≤21. Smaller valve size indexed to BSA was associated with re-operation (21.7 vs. 23.5 mm/m2). Predictors of reintervention by multivariable analysis were younger age (29% increase in hazard per 5-year decrease, p<0.001), Mitroflow (HR=4 to 8 versus other valves), and smaller valve size (20% increase in hazard per 1 mm decrease, p=0.002). The overall 1, 3 and 5-year survival rates were 94%, 90% and 85% without differences by valve (p=0.19). A concerning reduction in 5-year survival after bAVR is shown. Re-operation is common and varies by age and valve type. Further research is needed to guide valve choice and improve survival.

Abstract
BACKGROUND There are limited data about the range of diseases, natural history, age-appropriate endpoints and optimal care for children with pulmonary hypertension (PH), including the need for developing high quality patient registries of children with diverse forms of PH to enhance care and research. OBJECTIVE To characterise the distribution and clinical features of diseases associated with pediatric PH, including natural history, evaluation, therapeutic interventions and outcomes, as defined by the WSPH Classification. METHODS 1475 patients were enrolled into a multisite registry across the Pediatric Pulmonary Hypertension Network (PPHNet), comprised of 8 interdisciplinary PH programs. RESULTS WSPH Groups 1 (PAH) and 3 (lung disease) were the most common primary classifications (45% and 49% of subjects, respectively). The most common Group 3 conditions were BPD and CDH. Group 1 disease was predominantly associated with congenital heart disease (60%) and idiopathic (23% of Group 1 cases). In comparison with Group 1, Group 3 subjects had better disease resolution (HR=3.1, p<0.001), tended to be younger at diagnosis (0.3 (0.0,0.6) versus 1.6 (0.1,6.9) years (median (IQR); p<0.001), and were more often male (57% versus. 45%, p<0.001). Down syndrome (DS), the most common genetic syndrome in the registry, constituted 11% of the entire PH cohort. CONCLUSIONS We find a striking proportion of pediatric PH patients with Group 3 disorders, reflecting the growing recognition of PH in diverse developmental lung diseases. Greater precision of clinical phenotyping based on disease-specific characterization may further enhance care and research of pediatric PH.

Impact of pulmonary valve replacement on left ventricular rotational mechanics in repaired tetralogy of Fallot. J Cardiovasc Magn Reson 2021; 23:61. [PMID: 34024274 PMCID: PMC8142485 DOI: 10.1186/s12968-021-00750-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Accepted: 03/22/2021] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND In repaired tetralogy of Fallot (rTOF), abnormal left ventricular (LV) rotational mechanics are associated with adverse clinical outcomes. We performed a comprehensive analysis of LV rotational mechanics in rTOF patients using cardiac magnetic resonance (CMR) prior to and following surgical pulmonary valve replacement (PVR). METHODS In this single center retrospective study, we identified rTOF patients who (1) had both a CMR ≤ 1 year before PVR and ≤ 5 years after PVR, (2) had no other intervening procedure between CMRs, (3) had a body surface area > 1.0 m2 at CMR, and (4) had images suitable for feature tracking analysis. These subjects were matched to healthy age- and sex-matched control subjects. CMR feature tracking analysis was performed on a ventricular short-axis stack of balanced steady-state free precession images. Measurements included LV basal and apical rotation, twist, torsion, peak systolic rates of rotation and torsion, and timing of events. Associations with LV torsion were assessed. RESULTS A total of 60 rTOF patients (23.6 ± 7.9 years, 52% male) and 30 healthy control subjects (20.8 ± 3.1 years, 50% male) were included. Compared with healthy controls, rTOF patients had lower apical and basal rotation, twist, torsion, and systolic rotation rates, and these parameters peaked earlier in systole. The only parameters that were correlated with LV torsion were right ventricular (RV) end-systolic volume (r = - 0.28, p = 0.029) and RV ejection fraction (r = 0.26, p = 0.044). At a median of 1.0 year (IQR 0.5-1.7) following PVR, there was no significant change in LV rotational parameters versus pre-PVR despite reductions in RV volumes, RV mass, pulmonary regurgitation, and RV outflow tract obstruction. CONCLUSION In this comprehensive study of CMR-derived LV rotational mechanics in rTOF patients, rotation, twist, and torsion were diminished compared to controls and did not improve at a median of 1 year after PVR despite favorable RV remodeling.

Abstract
Cone repair (CR) uses native tissue for tricuspid valve (TV) repair and provides potential for growth. Results after CR were investigated in different age groups including several surgical modifications. Single institution retrospective analysis of all CR excluding neonatal procedures. Endpoints included TV reoperation, late tricuspid regurgitation (TR) and death. Between April 2006 and August 2019, 157 patients underwent CR at a median age of 11.7 years (range, 0.3-57.2). 20% (n=32) of patients had previous surgery. Repair modifications included atrial reduction (n=111,71%), right ventricular plication (n=85,55%), leaflet augmentation (n=36,23%), papillary muscle repositioning (n=50,32%), ring annuloplasty (n=70,45%). Early re-operation for recurrent TR occurred in 11 patients. Median follow-up time was 4.3 years (range, 9d-12.3y). There was no significant association between age at repair and time to TV reoperation (p=0.25). However, age <4 years at CR was identified as the most discriminating binary age threshold for the patients with TV reoperation (25.0% in <4y group vs 9.3% in the ≥4y group). Placement of an annuloplasty ring was protective against ≥moderate TR (OR=0.39, 95% CI 0.16-0.95, p=0.039). Freedom from late TV re-operation was 94.1% at 7 years. Survival was 97.9% at 6 years. Repair after age 18 years was associated with mortality in early follow-up (p=0.037). Mid-term results for CR are favorable in children and adults. Time to TV reoperation may be shorter when CR is performed before age four years, but this result requires confirmation in a larger sample. An annuloplasty ring should be considered when appropriate.

Abstract
Background Pediatric cardiomyopathy is a genetically heterogeneous disease with substantial morbidity and mortality. Current guidelines recommend genetic testing in children with hypertrophic, dilated, or restrictive cardiomyopathy, but practice variations exist. Robust data on clinical testing practices and diagnostic yield in children are lacking. This study aimed to identify the genetic causes of cardiomyopathy in children and to investigate clinical genetic testing practices. Methods and Results Children with familial or idiopathic cardiomyopathy were enrolled from 14 institutions in North America. Probands underwent exome sequencing. Rare sequence variants in 37 known cardiomyopathy genes were assessed for pathogenicity using consensus clinical interpretation guidelines. Of the 152 enrolled probands, 41% had a family history of cardiomyopathy. Of 81 (53%) who had undergone clinical genetic testing for cardiomyopathy before enrollment, 39 (48%) had a positive result. Genetic testing rates varied from 0% to 97% between sites. A positive family history and hypertrophic cardiomyopathy subtype were associated with increased likelihood of genetic testing (P=0.005 and P=0.03, respectively). A molecular cause was identified in an additional 21% of the 63 children who did not undergo clinical testing, with positive results identified in both familial and idiopathic cases and across all phenotypic subtypes. Conclusions A definitive molecular genetic diagnosis can be made in a substantial proportion of children for whom the cause and heritable nature of their cardiomyopathy was previously unknown. Practice variations in genetic testing are great and should be reduced. Improvements can be made in comprehensive cardiac screening and predictive genetic testing in first‐degree relatives. Overall, our results support use of routine genetic testing in cases of both familial and idiopathic cardiomyopathy. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT01873963.

Abstract
OBJECTIVES Fetal aortic valvuloplasty (FAV) for severe aortic stenosis (AS) has shown promise in averting progression to hypoplastic left heart syndrome. After FAV, predicting which fetuses will achieve a biventricular (BiV) circulation after birth remains challenging. Identifying predictors of postnatal circulation on late gestation echocardiography will improve parental counseling. METHODS Liveborn patients who underwent FAV and had late gestation echocardiography available were included (2000-2017, n = 96). Multivariable logistic regression and classification and regression tree analysis were utilized to identify independent predictors of BiV circulation. RESULTS Among 96 fetuses, 50 (52.1%) had BiV circulation at the time of neonatal discharge. In multivariable analysis, independent predictors of biventricular circulation included left ventricular (LV) long axis z-score (OR 3.2, 95% CI 1.8-5.7, p < 0.001), LV ejection fraction (OR 1.3, 95% CI 1.0-1.8, p = 0.023), anterograde aortic arch flow (OR 5.0, 95% CI 1.2-20.4, p = 0.024), and bidirectional or right-to-left foramen ovale flow (OR 4.6, 95% CI 1.4-15.8, p = 0.015). CONCLUSION Several anatomic and physiologic parameters in late gestation were found to be independent predictors of BiV circulation after FAV. Identifying these predictors adds to our understanding of LV growth and hemodynamics after FAV and may improve parental counseling.

Abstract
BACKGROUND Surgical resection of cardiac fibromas in children reduces hemodynamic and arrhythmia burden; however, little is known about postoperative left ventricular (LV) function. We aimed to evaluate factors associated with postoperative LV dysfunction. METHODS In this retrospective observational cohort study, imaging data were reviewed from 41 patients who had undergone surgical resection of a cardiac fibroma. Tumor volume was indexed to body surface area (tumor volume index). Right ventricular tumors were excluded from analysis of postoperative ventricular function. Postoperative regional wall motion abnormality score was defined as number of wall segments with regional wall motion abnormality, and LV dysfunction was defined as LV ejection fraction <50%. Cardiovascular magnetic resonance-derived strain was low if <5%ile by previously published normative data. RESULTS Of 41 patients who underwent resection at a median age of 2.1 years (range, 0.5-19), 37 fibromas were in the LV, (29 free wall and 8 septal), and 4 in the right ventricle. Preoperative median tumor volume index was 66 mL/m2 (range, 11-376). Of 37 patients with LV tumors, younger patients had larger tumor volume index and higher grades of preoperative mitral regurgitation (P<0.001). Larger tumor volume index correlated with higher postoperative regional wall motion abnormality score (P<0.001). By paired pre- and post-operative cardiovascular magnetic resonance (n=14), LV end-diastolic volume increased (mean 76 versus 101 mL/m2, P=0.011), with decreased LV ejection fraction (mean 60% versus 55%, P=0.014), a higher prevalence of low global circumferential strain (36% versus 64%, P=0.045), and decreased cardiac index (mean 4.8 versus 3.9 L/[min·m2], P=0.039). More than mild preoperative mitral regurgitation was the only independent predictor of predischarge LV dysfunction (odds ratio, 22 [95% CI, 2.8-179], P=0.008). CONCLUSIONS Surgical resection of LV fibroma is associated with regional wall motion abnormality, increased LV volume, and reduced systolic function. Children with significant preoperative mitral regurgitation are at highest risk for LV dysfunction and warrant ongoing close surveillance.

Abstract
Background The unpredictable trajectory of pediatric advanced heart disease makes prognostication difficult for physicians and informed decision‐making challenging for families. This study evaluated parent and physician understanding of disease burden and prognosis in hospitalized children with advanced heart disease. Methods and Results A longitudinal survey study of parents and physicians caring for patients with advanced heart disease age 30 days to 19 years admitted for ≥7 days was performed over a 1‐year period (n=160 pairs). Percentage agreement and weighted kappa statistics were used to assess agreement. Median patient age was 1 year (interquartile range, 1–5), 39% had single‐ventricle lesions, and 37% were in the cardiac intensive care unit. Although 92% of parents reported understanding their child's prognosis “extremely well” or “well,” 28% of physicians thought parents understood the prognosis only “a little,” “somewhat,” or “not at all.” Better parent‐reported prognostic understanding was associated with greater preparedness for their child's medical problems (odds ratio, 4.7; 95% CI, 1.4–21.7, P=0.02). There was poor parent–physician agreement in assessing functional class, symptom burden, and likelihood of limitations in physical activity and learning/behavior; on average, parents were more optimistic. Many parents (47%) but few physicians (6%) expected the child to have normal life expectancy. Conclusions Parents and physicians caring for children with advanced heart disease differed in their perspectives regarding prognosis and disease burden. Physicians tended to underestimate the degree of parent‐reported symptom burden. Parents were less likely to expect limitations in physical activity, learning/behavior, and life expectancy. Combined interventions involving patient‐reported outcomes, parent education, and physician communication tools may be beneficial.

Abstract
Importance Elective surgeries are primarily scheduled according to surgeon availability with less consideration of patients' postoperative cardiac intensive care unit (CICU) length of stay. Furthermore, the CICU census can exhibit a high rate of variation in which the CICU is operating at over-capacity, resulting in admission delays and cancellations; or under-capacity, resulting in underutilized labor and overhead expenditures. Objective To identify strategies to reduce variation in CICU occupancy levels and avoid late patient surgery cancellation. Design Monte Carlo simulation study of the daily and weekly CICU census at Boston Children's Hospital Heart Center. Data on all surgical admissions to and discharges from the CICU at Boston Children's Hospital between September 1, 2009 and November 2019 were included to obtain the distribution of length of stay for the simulation study. The available data allows us to model realistic length of stay samples that include short and extended lengths of stay. Main Outcomes Annual number of patient surgical cancellations and change in average daily census. Results We demonstrate that the models of strategic scheduling would result in up to 57% reduction in patient surgical cancellations, increase the historically low Monday census and decrease the historically higher late-mid-week (Wednesday and Thursday) censuses in our center. Conclusions and Relevance Use of strategic scheduling may improve surgical capacity and reduce the number of annual cancellations. The reduction of peaks and valleys in the weekly census corresponds to a reduction of underutilization and overutilization of the system.
