Fontan circulation and systemic disease - a retrospective cohort analysis over 35 years of follow-up: Fontan systemic disease at 35 years.

BACKGROUND: The Fontan operation provides lifesaving palliation for individuals with single ventricle (SV) physiology. Given recent concerns of systemic disease (SD) for patients with a Fontan circulation, we sought to 1) quantify the increase in SD incidence associated with the Fontan circulation; 2) identify the risk factor of SD; 3) assess the association between SD and mortality in patients with a Fontan circulation. METHODS: A matched retrospective cohort study design was adopted. From the Quebec Congenital Heart Disease (CHD) Database with up to 35 years of follow-up, patients who survived at least 30 days after the Fontan operation were identified. For each Fontan patient, patients with isolated ventricular septal defect (VSD) with the same sex and age were identified and 20 of them were randomly selected to form the control group. The presence of SD was defined as at least one hospitalization due to extra-cardiac complications including liver, respiratory, gastrointestinal or renal disease. Time-to-event analysis including Kaplan-Meier curve analysis and Cox proportional hazard models were conducted to assess the cumulative risk of SD, risk factors of SD, and the association between SD and 10-year mortality. RESULTS: A total of 533 patients with Fontan circulation were identified and matched with 10,280 VSD patients. The cumulative probabilities of SD at 10- and 35-years follow-up were 59.02% and 89.66% in patients with a Fontan circulation, 4-7 times of the probabilities in VSD patients (8.68% and 23.34%, respectively; LogRank tests p<0.0001). In Fontan patients, cardiovascular complications were associated with a 4.1-fold (95% CI: 3.52-4.88) higher risk of developing SD. Multisystem disease (>1 extra-cardiac organ affected) disease was associated with a 3.38-fold (95%CI: 1.73-6.60) increase in 10-year mortality risk when comparing to the absence of SD. CONCLUSIONS: This population-based study demonstrated that patients with a Fontan circulation had increased risk of SD, which in turn led to higher risk of mortality. These findings underscore the need for more systematic surveillance of cardiac and systemic disease for patients after Fontan operation.

Rationale and design of CHD PULSE: Congenital Heart Disease Project to Understand Lifelong Survivor Experience.

BACKGROUND: With improved survival of adults with congenital heart disease (CHD) comes a need to understand the lifelong outcomes of this population. The aim of this paper is to describe the rationale and design of Congenital Heart Disease Project to Understand Lifelong Survivor Experience (CHD PULSE), a study to determine long-term medical, neurocognitive, and psychosocial outcomes among adults with a history of intervention for CHD and to identify factors associated with those outcomes. METHODS: CHD PULSE is a cross-sectional survey conducted from September 2021 to April 2023 among adults aged 18 and older with a history of at least 1 intervention for CHD at 1 of 11 participating U.S. centers in the Pediatric Cardiac Care Consortium. Participants with CHD were asked to complete a 99-question survey on a variety of topics including: demographics, surgeries, health insurance, health care, heart doctors, general health, height and weight, education and work history, reproductive health (for women only), and COVID-19. To construct a control group for the study, siblings of survey respondents were invited to complete a similar survey. Descriptive statistics for demographics, disease severity, center, and method of survey completion were computed for participants and controls. Comparisons were made between participants and non-participants to assess for response bias and between CHD participants and sibling controls to assess for baseline differences. RESULTS: Among the 14,322 eligible participants, there were 3,133 respondents (21.9%) from 48 U.S. states with surveys returned for inclusion in the study. Sibling contact information was provided by 691 respondents, with surveys returned by 326 siblings (47.2%). The median age of participants was 32.8 years at time of survey completion, with an interquartile range of 27.2 years to 39.7 years and an overall range of 20.1 to 82.9 years. Participants were predominantly female (55.1%) and of non-Hispanic White race/ethnicity (87.1%). There were no differences between participants and non-participants regarding severity of CHD. Compared to nonparticipants, participants were more likely to be female, of older age, and be of non-Hispanic White race/ethnicity. Enrolled siblings were more likely to be female and slightly younger than participants. CONCLUSIONS: With surveys from 3,133 participants from across the U.S., CHD PULSE is poised to provide keen insights into the lifelong journey of those living with CHD, extending beyond mere survival. These insights will offer opportunities for informing strategies to enhance and improve future outcomes for this population of patients.

Design of a multi-institutional neurocognitive discovery study in adult congenital heart disease (MINDS-ACHD).

BACKGROUND: Neurocognitive dysfunction (NCD) is a common comorbidity among children with congenital heart disease (CHD). However, it is unclear how underlying CHD and its sequelae combine with genetics and acquired cardiovascular and neurological disease to impact NCD and outcomes across the lifespan in adults with CHD. METHODS: The Multi-Institutional Neurocognitive Discovery Study in Adults with Congenital Heart Disease (MINDS-ACHD) is a partnership between the Pediatric Heart Network (PHN) and the Adult Alliance for Research in Congenital Cardiology (AARCC) that examines objective and subjective neurocognitive function and genetics in young ACHD. This multicenter cross-sectional pilot study is enrolling 500 young adults between 18 and 30 years with moderate or severe complexity CHD at 14 centers in North America. Enrollment includes 4 groups (125 participants each): (1) d-looped Transposition of the Great Arteries (d-TGA); (2) Tetralogy of Fallot (TOF); (3) single ventricle (SV) physiology; and (4) "other moderately or severely complex CHD." Participants complete the standardized tests from the NIH Toolbox Cognitive Battery, the NeuroQoL, the Hospital Anxiety and Depression Scale, and the PROMIS Global QoL measure. Clinical and demographic variables are collected by interview and medical record review, and an optional biospecimen is collected for genetic analysis. Due to the COVID-19 pandemic, participation may be done remotely. Tests are reviewed by a Neurocognitive Core Laboratory. CONCLUSIONS: MINDS-ACHD is the largest study to date characterizing NCD in young adults with moderate or severely complex CHD in North America. Its results will provide valuable data to inform screening and management strategies for NCD in ACHD and improve lifelong care.

Disproportionate Negative Career Impact of the COVID-19 Pandemic on Female Pediatric Cardiologists in the Northeast United States.

The COVID-19 pandemic has had a dramatic impact on practicing physicians, with effects in clinical practice, academic pursuits, research endeavors, and personal lives. Women in medicine have been uniquely impacted. We examined the impact of the pandemic on the careers of pediatric cardiologists in the Northeast with an anonymous online survey. Participants reported demographic data, information on work hours, administrative burden, career satisfaction, academic productivity, and burnout. We approached 490 cardiologists and received 127 completed surveys (response rate 26%; 49% female). Among all respondents, 72% reported increased burnout, 43% reported decreased career satisfaction, and 57% reported decreased academic productivity. In multivariable ordinal regression analysis, when compared to male physicians, females were 2.4 times more likely to report decreased overall career satisfaction (p = 0.027), 2.6 times more likely to report decreased academic productivity (p = 0.028), and 2.6 times more likely to report increased feelings of burnout "to a large degree" (p = 0.022). Among all respondents, decreased career satisfaction was independently associated with increased household responsibility (OR = 4.4, p = 0.001). Increased administrative burden was independently associated with decreased academic productivity (OR = 2.6, p = 0.038). Open-ended responses highlighted loss of community due to remote work and blurring of the boundaries between work and home. Conversely, respondents appreciated flexibility to work remotely. In conclusion, the majority of pediatric cardiologists in the Northeast experienced negative career impacts due to the COVID-19 pandemic. Important gender differences emerged, with female physicians disproportionately reporting increased burnout, decreased career satisfaction, and decreased academic productivity.

Development of the Residual Lesion Score for congenital heart surgery: the RAND Delphi methodology.

BACKGROUND AND OBJECTIVE: The Residual Lesion Score is a novel tool for assessing the achievement of surgical objectives in congenital heart surgery based on widely available clinical and echocardiographic characteristics. This article describes the methodology used to develop the Residual Lesion Score from the previously developed Technical Performance Score for five common congenital cardiac procedures using the RAND Delphi methodology. METHODS: A panel of 11 experts from the field of paediatric and congenital cardiology and cardiac surgery, 2 co-chairs, and a consultant were assembled to review and comment on validity and feasibility of measuring the sub-components of intraoperative and discharge Residual Lesion Score for five congenital cardiac procedures. In the first email round, the panel reviewed and commented on the Residual Lesion Score and provided validity and feasibility scores for sub-components of each of the five procedures. In the second in-person round, email comments and scores were reviewed and the Residual Lesion Score revised. The modified Residual Lesion Score was scored independently by each panellist for validity and feasibility and used to develop the "final" Residual Lesion Score. RESULTS: The Residual Lesion Score sub-components with a median validity score of ≥7 and median feasibility score of ≥4 that were scored without disagreement and with low absolute deviation from the median were included in the "final" Residual Lesion Score. CONCLUSION: Using the RAND Delphi methodology, we were able to develop Residual Lesion Score modules for five important congenital cardiac procedures for the Pediatric Heart Network's Residual Lesion Score study.

Differences in perceptions of transition readiness between parents and teens with congenital heart disease: do parents and teens agree?

BACKGROUND: Amongst patients with CHD, the time of transition to adulthood is associated with lapses in care leading to significant morbidity. The purpose of this study was to identify differences in perceptions between parents and teens in regard to transition readiness. METHODS: Responses were collected from 175 teen-parent pairs via the validated CHD Transition Readiness survey and an information request checklist. The survey was distributed via an electronic tablet at a routine clinic visit. RESULTS: Parents reported a perceived knowledge gap of 29.2% (the percentage of survey items in which a parent believes their teen does not know), compared to teens self-reporting an average of 25.9% of survey items in which they feel deficient (p = 0.01). Agreement was lowest for long-term medical needs, physical activities allowed, insurance, and education. In regard to self-management behaviours, agreement between parent and teen was slight to moderate (weighted κ statistic = 0.18 to 0.51). For self-efficacy, agreement ranged from slight to fair (weighted κ = 0.16 to 0.28). Teens were more likely to request information than their parents (79% versus 65% requesting at least one item) particularly in regard to pregnancy/contraception and insurance. CONCLUSION: Parents and teens differ in several key perceptions regarding knowledge, behaviours, and feelings related to the management of heart disease. Specifically, parents perceive a higher knowledge deficit, teens perceive higher self-efficacy, and parents and teens agree that self-management is low.

Interobserver agreement of the anatomic and physiological classification system for adult congenital heart disease.

The Anatomic and Physiological (AP) classification system proposed in the 2018 American College of Cardiology/American Heart Association adult congenital heart disease (ACHD) guidelines assigns 2 dimensions to each patient: anatomic class (AnatC) and physiological stage (PhyS). This approach has not been tested in practice; we assessed interrater reliability and identified sources of disagreement. METHODS: Consensus definitions for AP categories were developed with input from 4 experts. Research assistants (RAs) assigned AnatC/PhyS for patients in the Boston ACHD Biobank, a prospectively enrolled cohort of ambulatory ACHD patients ≥18 years old seen between 2012 and 2019. Two (of 4) expert reviewers then independently assigned AnatC/PhyS for 41 patients. Interrater reliability was assessed with linearly weighted kappa (κω) for agreement between (1) experts and (2) an RA and an expert. Experts examined disagreements and identified sources of variability and areas requiring clarification. RESULTS: Interexpert agreement for AnatC was excellent, with agreement on 38/41 (92.7%) cases and κω 0.88 [0.75, 1.01]. Agreement for PhyS was less robust, with consensus on 24/41 cases (59.5%), κω 0.57 [0.39, 0.75]. Expert-RA agreement was lower for AnatC (κω 0.77 [0.60, 0.95]), whereas PhyS was similar to interexpert agreement (κω 0.53 [0.34, 0.72]). There was ambiguity in the definitions of (1) arrhythmia status, (2) cyanotic CHD, and (3) valve disease. CONCLUSIONS: Although AnatC can be assessed reliably, that is not true for the PhyS part of the AP classification proposed in the 2018 American College of Cardiology/American Heart Association guidelines. Reliability of PhyS would be strengthened by more precise definitions readily interpretable in clinical practice.

Transition Readiness in Teens and Young Adults with Congenital Heart Disease: Can We Make a Difference?

OBJECTIVES: To examine changes in transition readiness (knowledge, self-efficacy, self-management) over time and explore factors associated with transition readiness, including psychosocial quality of life (QOL) and health service utilization in teens/young adults with congenital heart disease. STUDY DESIGN: In a multicenter prospective cohort study, 356 patients, age 14-27 years, completed transition readiness and QOL assessments at routine cardiology visits at baseline and 1-year follow-up. RESULTS: Median patient age was 19.8 years at 1.03 years (IQR 0.98-1.24) following baseline transition readiness assessment. Average knowledge deficit scores decreased at follow-up (P < .0001) and self-efficacy scores increased (P < .0001). Self-management scores increased (P < .0001), but remained low (mean 57.7, 100-point scale). Information was requested by 73% of patients at baseline and was associated with greater increase in knowledge at follow-up (P = .005). Increased knowledge (P = .003) and perceived self-efficacy (P = .01) were associated with improved psychosocial QOL, but not health service utilization at follow-up. Patients who preferred face-to-face information from healthcare providers (47%) vs other information sources were more likely to request information (P < .0001). In patients <18 years old, greater agreement between teen and parental perception of teen's knowledge was associated with greater increase in patient knowledge (P = .02) and self-efficacy (P = .003). CONCLUSION: Transition readiness assessment demonstrated improved knowledge, self-efficacy, and self-management at 1-year follow-up in teens/young adults with congenital heart disease. Improved knowledge and self-efficacy were associated with improved psychosocial QOL. Self-management remained low. Supplemental media for conveying information and greater involvement of parents may be needed to optimize transition readiness.

Difference in the prevalence of intracardiac thrombus on the first presentation of atrial fibrillation versus flutter in the pediatric and congenital heart disease population.

INTRODUCTION: Guidelines recommend trans-esophageal echocardiography (TEE) for patients with atrial fibrillation (AF) or atrial flutter (AFL) for >48 h, due to risk of intracardiac thrombus formation. With growing evidence that AFL in adults with structurally normal hearts has less thrombogenic potential compared to AF, and the need for TEE questioned, we compared prevalence of intracardiac thrombus detected by TEE in pediatric and congenital heart disease (CHD) patients presenting in AF and AFL. METHODS/RESULTS: Single-center, cross-sectional analysis for unique first-time presentations of patients for either AF, AFL, or intra-atrial reentrant tachycardia (IART) between 2000 and 2019. Patients were categorized by presenting arrhythmia (AF vs. AFL/IART), with the exclusion of other forms of atrial tachycardia, hemodynamic instability, chronic anti-coagulation before TEE, and presentation for a reason other than TEE examination for thrombus. A total of 201 patients had TEE with co-diagnosis of AF or AFL. Of these, 105 patients (29 AF, 76 AFL) met inclusion criteria, with no difference in age between AF (median 24.9 years; IQR 18.6-38.3 years) and AFL/IART (23.3 years; 15.4-38.4 years). The prevalence of thrombus in the entire cohort was 9.5%, with no difference between AF (13.8%) and AFL groups (7.9%), p = .46. Patients with thrombus demonstrated no difference in age, systemic ventricular function, cardiac complexity, or CHADS2/CHA2DS2VASc score at presentation. CONCLUSIONS: The risk for intracardiac thrombus is high in the pediatric and CHD population, with no apparent distinguishing factors to warrant a change in the recommendations for TEE, with all levels of cardiac complexity being at risk for clot.

Exposure to Low-Dose Ionizing Radiation From Cardiac Procedures and Malignancy Risk in Adults With Congenital Heart Disease.

BACKGROUND: Adults with congenital heart disease (CHD) are exposed to increasing amounts of low-dose ionizing radiation (LDIR) from cardiac procedures. Cancer prevalence in this population is higher than in the general population. This study estimates the association between LDIR exposure from cardiac procedures and incident cancer in adult patients with CHD. METHODS: The study population derived from the Quebec Congenital Heart Disease Database. We measured cumulative numbers of LDIR-related cardiac procedures for each patient until 1 year before the time of cancer diagnosis or administrative censoring. To assess the association between LDIR exposure and cancer risk, we conducted a nested case-control study and matched cancer cases with controls on sex, CHD severity, birth year, and age. RESULTS: The study included 24 833 adult patients with CHD aged 18 to 64 years from 1995 to 2009. In >250 791 person-years of follow-up, 602 cancer cases were observed (median age, 55.4 years). The cumulative incidence of cancer estimated up to 64 years of age was 15.3% (95% confidence interval [CI], 14.2-16.5). Cases had more LDIR-related cardiac procedures than controls (1410 versus 921 per 1000 adult patients with CHD, P<0.0001). Cumulative LDIR exposure was independently associated with cancer (odds ratio [OR], 1.08 per procedure; 95% CI, 1.04-1.13). Similar results were obtained by using dose estimates for LDIR exposure (OR, 1.10 per 10 mSv; 95% CI, 1.05-1.15) with a possible dose-related response. The effect measure was in the same direction, and the association was persistent for exposure from ≥6 procedures in all sensitivity analyses: after excluding most smoking-related cancer cases (OR, 1.10 per procedure; 95% CI, 1.05-1.16 and OR when exposure from ≥6 procedures, 3.08; 95% CI, 1.77-5.37), and after applying a 3-year lag period (OR, 1.09 per procedure; 95% CI, 1.03-1.14 and OR when exposure from ≥6 procedures: 2.58; 95% CI, 1.43-4.69). CONCLUSIONS: To our knowledge, this is the first large population-based study to analyze and document the association between LDIR-related cardiac procedures and incident cancer in the population of adults with CHD. Confirmations of these findings by prospective studies are needed to reinforce policy recommendations for radiation surveillance in patients with CHD where no regulation currently exists. Physicians ordering and performing cardiac imaging should ensure that exposure is as low as reasonably achievable without sacrificing quality of care.

Exposure to Low-Dose Ionizing Radiation From Cardiac Procedures in Patients With Congenital Heart Disease: 15-Year Data From a Population-Based Longitudinal Cohort.

BACKGROUND: The burden of low-dose ionizing radiation (LDIR) exposure from medical procedures among individuals with congenital heart disease (CHD) is unknown. In this longitudinal population-based study, we sought to determine exposure to LDIR-related cardiac imaging and therapeutic procedures in children and adults with CHD. METHODS AND RESULTS: In an analysis of the Quebec CHD database, exposure to the following LDIR-related cardiac procedures was recorded: catheter-based diagnostic procedures, structural heart interventions, coronary interventions, computed tomography scans of the chest, nuclear procedures, and pacemaker/implantable cardioverter-defibrillator insertion and repair. From 1990 to 2005, there were 16 253 LDIR-exposed patients with CHD with 317 988 patient-years of available follow-up. The total number of LDIR-related procedures increased from 18.5 to 51.9 per 1000 CHD patients per year (P<0.0001). This increase was attributable to increases in rates per 1000 CHD patients in diagnostic cardiac catheterizations (11.7 to 13.7 per 1000), structural heart interventions (1.0 to 5.2 per 1000), coronary interventions (1.0 to 2.4 per 1000), pacemaker/implantable cardioverter-defibrillator insertions (1.6 to 4.4 per 1000), nuclear procedures (4.2 to 13.8 per 1000), and computed tomography scans of the chest (2.5 to 12.3 per 1000). Over time, among children with CHD, the median age at first LDIR procedure decreased from 5.0 years to 9.6 months. Severity of CHD significantly predicted extent of exposure. CONCLUSIONS: From 1990 to 2005, patients with CHD were exposed to increasing numbers of LDIR-emitting cardiac procedures. This exposure occurred at progressively younger ages. These findings provide an important perspective on longitudinal LDIR exposure in this at-risk population.

Aortic root dilatation in adults with surgically repaired tetralogy of fallot: a multicenter cross-sectional study.

BACKGROUND: Although aortic root pathology has been described in patients with tetralogy of Fallot, the scope of the problem remains poorly defined. We sought to determine the prevalence and predictors of aortic root dilatation in adults with repaired tetralogy of Fallot. METHODS AND RESULTS: A multicenter cross-sectional study was conducted with standardized reassessment of echocardiographic parameters in 474 adults (≥18 years) with surgically repaired tetralogy of Fallot or pulmonary atresia with ventricular septal defect. The aortic root was measured in a parasternal long-axis view, in diastole, at the level of the sinus of Valsalva. Prevalence and predictors of an absolute diameter ≥40 mm and of an observed-to-expected ratio >1.5 were assessed. The aortic root dimension was ≥40 mm in 28.9% (95% confidence interval, 26.9%-30.9%). In multivariate analyses, the only independently associated factor was male sex (odds ratio, 4.48; 95% confidence interval, 1.55-12.89; P=0.006). The prevalence of an observed-to-expected aortic root dimension ratio >1.5 was 6.6% (95% confidence interval, 5.3%-7.9%). It was associated with pulmonary atresia and moderate or severe aortic regurgitation in univariate analyses, but no independent predictor was identified. The side of the aortic arch was not associated with aortic root dimension. The prevalence of moderate or severe aortic regurgitation was 3.5% (95% confidence interval, 2.7%-4.2%). CONCLUSIONS: Although nearly one third of adults with repaired tetralogy of Fallot have an aortic root diameter ≥40 mm, the prevalence of a dilated aortic root, when defined by an indexed ratio of observed-to-expected values, is low. Similarly, moderate or severe aortic regurgitation is uncommon.

Health Service Use and Costs During Pregnancy Among Privately Insured Individuals With Congenital Heart Disease.

Importance: Individuals with congenital heart disease (CHD) are increasingly reaching childbearing age, are more prone to adverse pregnancy events, and uncommonly undergo recommended cardiac evaluations. Data to better understand resource allocation and financial planning are lacking. Objective: To examine health care use and costs for patients with CHD during pregnancy. Design, Setting, and Participants: This retrospective cohort study was performed from January 1, 2010, to December 31, 2016, using Merative MarketScan commercial insurance data. Participants included patients with CHD and those without CHD matched 1:1 by age, sex, and insurance enrollment year. Pregnancy claims were identified for all participants. Data were analyzed from September 2022 to March 2024. Exposures: Baseline characteristics (age, US region, delivery year, insurance type) and pregnancy-related events (obstetric, cardiac, and noncardiac conditions; birth outcomes; and cesarean delivery). Main Outcomes and Measures: Health service use (outpatient physician, nonphysician, emergency department, prescription drugs, and admissions) and costs (total and out-of-pocket costs adjusted for inflation to represent 2024 US dollars). Results: A total of 11 703 pregnancies (mean [SD] maternal age, 31.5 [5.4] years) were studied, with 2267 pregnancies in 1785 patients with CHD (492 pregnancies in patients with severe CHD and 1775 in patients with nonsevere CHD) and 9436 pregnancies in 7720 patients without CHD. Compared with patients without CHD, pregnancies in patients with CHD were associated with significantly higher health care use (standardized mean difference [SMD] range, 0.16-1.46) and cost (SMD range, 0.14-0.55) except for out-of-pocket inpatient and ED costs. After adjustment for covariates, having CHD was independently associated with higher total (adjusted cost ratio, 1.70; 95% CI, 1.57-1.84) and out-of-pocket (adjusted cost ratio, 1.40; 95% CI, 1.22-1.58) costs. The adjusted mean total costs per pregnancy were $15 971 (95% CI, $15 480-$16 461) for patients without CHD, $24 290 (95% CI, $22 773-$25 806) for patients with any CHD, $26 308 (95% CI, $22 788-$29 828) for patients with severe CHD, and $23 750 (95% CI, $22 110-$25 390) for patients with nonsevere CHD. Patients with vs without CHD incurred $8319 and $700 higher total and out-of-pocket costs per pregnancy, respectively. Conclusions and Relevance: This study provides novel, clinically relevant estimates for the cardio-obstetric team, patients with CHD, payers, and policymakers regarding health care and financial planning. These estimates can be used to carefully plan for and advocate for the comprehensive resources needed to care for patients with CHD.

Outcomes in adult congenital heart disease patients with Down syndrome undergoing cardiac surgery.

BACKGROUND: As the life expectancy of patients with Down syndrome (DS) improves, the number of older DS patients requiring cardiac surgery for congenital heart disease will increase. Perioperative risk factors and outcomes in these patients are unknown. METHODS: In a multicenter retrospective study, teenage and adult DS patients undergoing cardiac surgery between 2008-2018 were matched by age and surgical procedure with non-DS patients. Demographic, medical, and surgical characteristics were compared. Outcome measures were length of stay (LOS), duration of mechanical ventilation, need for non-invasive positive pressure ventilation (NIPPV) and reintubation, additional cardiac interventions, postoperative infections, and early postoperative mortality. Risk factors for extended hospital LOS (>10 days) were explored using multivariable logistic regression. RESULTS: We compared 121 DS patients to 121 non-DS patients. DS patients had a longer median LOS (7 vs. 5 days, p<0.001), longer duration of mechanical ventilation (12.5 vs. 6.7 hours, p<0.001), greater need for NIPPV or reintubation (26% vs. 4%, p<0.001), and higher likelihood of postoperative infections (10% vs. 2%, p=0.035). There was no early mortality. Pre-operative risk factors for extended LOS for DS patients included pulmonary medication use (OR 4.0, p=0.046), history of immunodeficiency (OR 10.4, p=0.004), or ≥moderate tricuspid regurgitation (OR 12.7, p<0.001). CONCLUSIONS: Teenage and adult DS patients undergoing congenital cardiac surgery had a longer hospital LOS and more postoperative respiratory and infection complications compared to non-DS patients without increased mortality. Cardiac surgery can be performed safely in older DS patients. Management of pulmonary disease, immunodeficiency, and tricuspid regurgitation may mitigate risk.

Social Determinants of Health Including Child Opportunity Index Leading to Gaps in Care for Patients With Significant Congenital Heart Disease.

BACKGROUND: Gaps in care (GIC) are common for patients with congenital heart disease (CHD) and can lead to worsening clinical status, unplanned hospitalization, and mortality. Understanding of how social determinants of health (SDOH) contribute to GIC in CHD is incomplete. We hypothesize that SDOH, including Child Opportunity Index (COI), are associated with GIC in patients with significant CHD. METHODS AND RESULTS: A total of 8554 patients followed at a regional specialty pediatric hospital with moderate to severe CHD seen in cardiology clinic between January 2013 and December 2015 were retrospectively reviewed. SDOH factors including race, ethnicity, language, and COI calculated based on home address and zip code were analyzed. GIC of >3.25 years were identified in 32% (2709) of patients. GIC were associated with ages 14 to 29 years (P<0.001), Black race or Hispanic ethnicity (P<0.001), living ≥150 miles from the hospital (P=0.017), public health insurance (P<0.001), a maternal education level of high school or less (P<0.001), and a low COI (P<0.001). Multivariable analysis showed that GIC were associated with age ≥14 years, Black race or Hispanic ethnicity, documenting <3 caregivers as contacts, mother's education level being high school or less, a very low/low COI, and insurance status (C statistic 0.66). CONCLUSIONS: One-third of patients followed in a regional referral center with significant CHD experienced a substantial GIC (>3.25 years). Several SDOH, including a low COI, were associated with GIC. Hospitals should adopt formal GIC improvement programs focusing on SDOH to improve continuity of care and ultimately overall outcomes for patients with CHD.

Recommendations for Centers Performing Pediatric Heart Surgery in the United States.

Care and outcomes for the more than 40,000 patients undergoing pediatric and congenital heart surgery in the United States annually are known to vary widely. While consensus recommendations have been published across numerous fields as one mechanism to promote a high level of care delivery across centers, it has been more than two decades since the last pediatric heart surgery recommendations were published in the United States. More recent guidance is lacking, and collaborative efforts involving the many disciplines engaged in caring for these children have not been undertaken to date. The present initiative brings together professional societies spanning numerous care domains and congenital cardiac surgeons, pediatric cardiologists, nursing, and other healthcare professionals from diverse programs around the country to develop consensus recommendations for United States centers. The focus of this initial work is on pediatric heart surgery, and it is recommended that future efforts focus in detail on the adult congenital population. We describe the background, rationale, and methodology related to this collaborative effort, and recommendations put forth for Essential Care Centers (essential services necessary for any program), and Comprehensive Care Centers (services to optimize comprehensive and high-complexity care), encompassing structure, process, and outcome metrics across 14 domains.
