The burden of psychological trauma and post-traumatic stress disorder among adults with congenital heart disease: PTSD in ACHD.

Psychological trauma, symptoms of post-traumatic stress disorder (PTSD), and mental health conditions are common in adult congenital heart disease (ACHD). There is a gap in research examining PTSD in ACHD using the current Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) criteria in assessing patient characteristics and experiences with trauma-focused treatment. Surveys were offered to outpatients over a 6-month enrollment period to be completed by way of a QR code on their personal smart phone. Patient-reported items include a detailed medical and psychosocial history, the Oslo social support scale, adverse childhood experiences survey, and the PTSD checklist for DSM-5. Of 158 patients (77% moderate or complex heart disease) who provided complete data, a provisional diagnosis of PTSD was found in 48 patients (30%) using a PTSD checklist for DSM-5 cut-off score of ≥31. A positive PTSD screen was associated with younger age, nonwhite race, presence of heart failure, lower New York Heart Association functional class, lower linear quality of life score, lower Oslo social support scale score, an insecure caregiver relation, period of unemployment, emergency department visits, medication nonadherence, and coexisting mental health disorders. Complexity of heart disease and number of surgical and/or catheter-based interventions were not associated with PTSD, although having undergone no cardiac surgeries until adulthood (aged ≥18 years) was associated with a lower prevalence of PTSD. Those who screened positive for PTSD were more likely to report multiple traumatic events, including noncardiac traumatic events. Only 14 of 48 patients (29%) reported a known diagnosis of PTSD, although 44 patients (92%) reported having ever seen a mental health provider. A total of 18 patients (38%) reported currently having a mental health provider. A total of 30 patients (62%) had heard of at least 1 evidence-based trauma-informed therapy, and 14 (29%) had tried at least 1. In conclusion, using the DSM-5 criteria, we observed a high prevalence of potential PTSD in ACHD associated with several novel cardiac and psychosocial patient factors. Future longitudinal studies will be necessary to establish causality. Few patients with ACHD have been formally diagnosed with PTSD or have experience with evidence-based trauma-informed therapies.

Testing the diagnostic accuracy of common questions for seizure diagnosis: Challenges and future directions.

OBJECTIVE: The aim of this study was to evaluate the diagnostic accuracy of common interview questions used to distinguish a diagnosis of epilepsy from seizure mimics including non-epileptic seizures (NES), migraine, and syncope. METHODS: 200 outpatients were recruited with an established diagnosis of focal epilepsy (n = 50), NES (n = 50), migraine (n = 50), and syncope (n = 50). Patients completed an eight-item, yes-or-no online questionnaire about symptoms related to their events. Sensitivity and specificity were calculated. Using a weighted scoring for the questions alone with baseline characteristics, the overall questionnaire was tested for diagnostic accuracy. RESULTS: Of individual questions, the most sensitive one asked if events are sudden in onset (98 % sensitive for epilepsy (95 % CI: 89 %, 100 %)). The least sensitive question asked if events are stereotyped (46 % sensitive for epilepsy (95 % CI: 32 %, 60 %)). Overall, three of the eight questions showed an association with epilepsy as opposed to mimics. These included questions about "sudden onset" (OR 10.76, 95 % CI: (1.66, 449.21) p = 0.0047), "duration < 5 min" (OR 3.34, 95 % CI: (1.62, 6.89), p = 0.0008), and "duration not > 30 min" (OR 4.44, 95 % CI: (1.94, 11.05), p = <0.0001). When individual seizure mimics were compared to epilepsy, differences in responses were most notable between the epilepsy and migraine patients. Syncope and NES were most similar in responses to epilepsy. The overall weighted questionnaire incorporating patient age and sex produced an area under the ROC curve of 0.80 (95 % CI: 0.74, 0.87)). CONCLUSION: In this study, we examined the ability of common interview questions used by physicians to distinguish between epilepsy and prevalent epilepsy mimics, specifically NES, migraines, and syncope. Using a weighted scoring system for questions, and including age and sex, produced a sensitive and specific predictive model for the diagnosis of epilepsy. In contrast to many prior studies which evaluated either a large number of questions or used methods with difficult practical application, our study is unique in that we tested a small number of easy-to-understand "yes" or "no" questions that can be implemented in most clinical settings by non-specialists.

Submaximal Exercise Response is Associated with Future Hypertension in Patients with Coarctation of the Aorta.

Hypertension (HTN) is common in patients with a history of coarctation of the aorta (CoA) and remains underrecognized and undertreated. Studies in the non-coarctation otherwise healthy adult population have correlated an exaggerated blood pressure response during mild to moderate exercise with subsequent diagnosis of HTN. The goal of this study was to determine if blood pressure response to submaximal exercise in normotensive CoA patients correlated with development of HTN.Retrospective chart review was performed in individuals ≥ 13 years old with CoA and no diagnosis of HTN at time of cardiopulmonary exercise testing (CPET). Systolic blood pressure (SBP) during CPET at rest, submax 1 (stage 1 Bruce or minute 2 bicycle ramp), submax 2 (stage 2 Bruce or minute 4 bicycle ramp), and peak were recorded. The primary composite outcome was HTN diagnosis or initiation of anti-hypertensive medications at follow up.There were 177 patients (53% female, median age 18.5 years), of whom 38 patients (21%) met composite outcome during a median follow up of 46 months. Men were more likely to develop hypertension. Age at repair and age at CPET were not significant covariates. At each stage of CPET, SBP was significantly higher in those who met the composite outcome. Submax 2 SBP ≥ 145 mmHg was 75% sensitive, 71% specific in males and 67% sensitive, 76% specific in females for development of composite outcome.Our study shows an exaggerated SBP response to submaximal exercise may portend an increased risk of developing hypertension during short- to mid-term follow up.

Secondary analysis of electronic opt-out consent in pragmatic research: A study design method to diversify clinical trials?

We conducted a multi-center pragmatic trial of a low-risk intervention focused on medication adherence using an opt-out consent approach, where patients could opt out by letter and then electronically. We focus on the cohort after opt-out by mail. Here, we describe that 8% of patients opted out electronically, resulting in a 92% participation rate. Patients who self-identify as Black or Hispanic were less likely to opt out in the study, and half the study cohort was female. This demographic data is useful for planning future trials employing this approach.

Sustained monomorphic ventricular tachycardia as the presenting sign of Chagas' cardiomyopathy in a low prevalence setting, diagnosis and management challenges. A case report.

Approximately 300,000 people in the United States are estimated to have Chagas' disease, with cardiac manifestations including arrhythmias occurring in 20%-30% of patients. We report a patient diagnosed with Chagas' cardiomyopathy after presenting in ventricular tachycardia. This patient was asymptomatic before her presentation with recurrent episodes of ventricular tachycardia, which motivated us to screen her since she was an immigrant from an endemic Chagas region. This manuscript highlights some of the characteristic cardiac magnetic resonance imaging (MRI) and electrophysiology findings present in patients with Chagas' cardiomyopathy. We also detail the management of patients with Chagas' cardiomyopathy who have suffered from ventricular tachycardia.

Health Care Usage Among Adolescents With Congenital Heart Defects at 5 Sites in the United States, 2011 to 2013.

Background We sought to characterize health care usage for adolescents with congenital heart defects (CHDs) using population-based multisite surveillance data. Methods and Results Adolescents aged 11 to 18 years with ≥1 CHD-related diagnosis code and residing in 5 US sites were identified in clinical and administrative data sources for the years 2011 to 2013. Sites linked data on all inpatient, emergency department (ED), and outpatient visits. Multivariable log-binomial regression models including age, sex, unweighted Charlson comorbidity index, CHD severity, cardiology visits, and insurance status, were used to identify associations with inpatient, ED, and outpatient visits. Of 9626 eligible adolescents, 26.4% (n=2543) had severe CHDs and 21.4% had Charlson comorbidity index >0. At least 1 inpatient, ED, or outpatient visit was reported for 21%, 25%, and 96% of cases, respectively. Cardiology visits, cardiac imaging, cardiac procedures, and vascular procedures were reported for 38%, 73%, 10%, and 5% of cases, respectively. Inpatient, ED, and outpatient visits were consistently higher for adolescents with severe CHDs compared with nonsevere CHDs. Adolescents with severe and nonsevere CHDs had higher health care usage compared with the 2011 to 2013 general adolescent US population. Adolescents with severe CHDs versus nonsevere CHDs were twice as likely to have at least 1 inpatient visit when Charlson comorbidity index was low (Charlson comorbidity index =0). Adolescents with CHDs and public insurance, compared with private insurance, were more likely to have inpatient (adjusted prevalence ratio, 1.5 [95% CI, 1.3-1.7]) and ED (adjusted prevalence ratio, 1.6 [95% CI, 1.4-1.7]) visits. Conclusions High resource usage by adolescents with CHDs indicates a substantial burden of disease, especially with public insurance, severe CHDs, and more comorbidities.

Hepatic abnormalities in youth with Turner syndrome.

BACKGROUND & AIMS: Liver disease in children with Turner Syndrome (TS) is poorly understood relative to associated growth, cardiac and reproductive complications. This study sought to better characterize hepatic abnormalities in a large national cohort of youth with TS. METHODS: Using electronic health record data from PEDSnet institutions, 2145 females with TS were matched to 8580 females without TS on eight demographic variables. Outcomes included liver enzymes (AST and ALT) stratified as normal, 1-2 times above the upper limit of normal (ULN), 2-3 times ULN and >3 times ULN, as well as specific liver disease diagnoses. RESULTS: Fifty-eight percent of youth with TS had elevated liver enzymes. Patients with TS had higher odds of enzymes 1-2 times ULN (OR: 1.7, 95% CI: 1.4-1.9), 2-3 times ULN (OR: 2.7, 95% CI: 1.7-3.3) and >3 times ULN (OR: 1.7, 95% CI: 1.3-2.2). They also had higher odds of any liver diagnosis (OR: 2.4, 95% CI: 1.7-3.3), fatty liver disease (OR: 1.9, 95% CI: 1.1-3.2), hepatitis (OR: 3.7, 95% CI: 1.9-7.1), cirrhosis/fibrosis (OR: 5.8, 95% CI: 1.3-25.0) and liver tumour/malignancy (OR: 4.8, 95% CI: 1.4-17.0). In a multinomial model, age, BMI and presence of cardiovascular disease or diabetes significantly increased the odds of elevated liver enzymes in girls with TS. CONCLUSIONS: Youth with TS have higher odds for elevated liver enzymes and clinically significant liver disease compared with matched controls. These results emphasize the need for clinical screening and additional research into the aetiology and treatment of liver disease in TS. LAY SUMMARY: Turner Syndrome, a chromosomal condition in which females are missing the second sex chromosome, is often associated with short stature, infertility and cardiac complications. Liver abnormalities are less well described in the literature. In this study, nearly 60% of youth with TS have elevated liver enzymes. Furthermore, patients with TS had a diagnosis of liver disease more often than patients without TS. Our results support the importance of early and consistent liver function screening and of additional research to define mechanisms that disrupt liver function in paediatric TS females.

Operational and Ethical Considerations for a National Adult Congenital Heart Disease Database.

As more adults survive with congenital heart disease, the need to better understand the long-term complications, and comorbid disease will become increasingly important. Improved care and survival into the early and late adult years for all patients equitably requires accurate, timely, and comprehensive data to support research and quality-based initiatives. National data collection in adult congenital heart disease will require a sound foundation emphasizing core ethical principles that acknowledge patient and clinician perspectives and promote national collaboration. In this document we examine these foundational principles and offer suggestions for developing an ethically responsible and inclusive framework for national ACHD data collection.

Post-traumatic stress disorder, anxiety, and depression among adults with congenital heart defects.

BACKGROUND: Due to invasive treatments and stressors related to heart health, adults with congenital heart defects (CHDs) may have an increased risk of post-traumatic stress disorder (PTSD), anxiety, and/or depressive disorders. Our objectives were to estimate the prevalence of these disorders among individuals with CHDs. METHODS: Using IBM® MarketScan® Databases, we identified adults age 18-49 years with ≥2 outpatient anxiety/depressive disorder claims on separate dates or ≥1 inpatient anxiety/depressive disorder claim in 2017. CHDs were defined as ≥2 outpatient CHD claims ≥30 days apart or ≥1 inpatient CHD claim documented in 2007-2017. We used log-binomial regression to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for associations between CHDs and anxiety/depressive disorders. RESULTS: Of 13,807 adults with CHDs, 12.4% were diagnosed with an anxiety or depressive disorder. Adults with CHDs, compared to the 5,408,094 without CHDs, had higher prevalence of PTSD (0.8% vs. 0.5%; aPR: 1.5 [CI: 1.2-1.8]), anxiety disorders (9.9% vs. 7.5%; aPR: 1.3 [CI: 1.3-1.4]), and depressive disorders (6.3% vs. 4.9%; aPR: 1.3 [CI: 1.2-1.4]). Among individuals with CHDs, female sex (aPR range: 1.6-3.3) and inpatient admission (aPR range 1.1-1.9) were associated with anxiety/depressive disorders. CONCLUSION: Over 1 in 8 adults with CHDs had diagnosed PTSD and/or other anxiety/depressive disorders, 30-50% higher than adults without CHDs. PTSD was rare, but three times more common in women with CHDs than men. Screening and referral for services for these conditions in people with CHDs may be beneficial.

Endocarditis Caused by Candida parapsilosis Presenting With Severe Thrombocytopenia in a Patient With Tetralogy of Fallot.

Infective endocarditis (IE) occurs more frequently in individuals living with congenital heart disease, often with high morbidity and mortality. Although gram-positive bacterial infections commonly cause IE, prosthetic valves are a known risk factor for fungal IE. We report a case of prosthetic pulmonary valve Candida parapsilosis IE in a 58-year-old male with repaired tetralogy of Fallot. He presented with fatigue, petechiae, and hematochezia. He had severe thrombocytopenia from idiopathic/immune thrombocytopenia purpura, which resolved with steroids and immunoglobulin. Treatment with antifungals as well as a surgical pulmonary valve replacement resulted in recovery without relapse at greater than a year.

ST-Elevation Myocardial Infarction due to Acute Thrombosis in an Adolescent With COVID-19.

STEMI can be the presenting diagnosis in adults with COVID-19; presented is a case of a 15-year-old girl with coronary thrombosis-induced STEMI associated with COVID-19. ST-elevation myocardial infarction (MI) is an identified presentation of coronavirus disease 2019 in adults but has not been reported in children. We present a case of a 15-year-old girl with a coronary thrombosis-induced ST-elevation MI in the setting of acute severe acute respiratory syndrome coronavirus 2 infection, not associated with multisystem inflammatory syndrome in children. The patient presented with chest pain, ST elevation, and myocardial dysfunction. Coronary angiography identified thrombosis treated with anticoagulation and antiplatelet therapy. MI must be considered in children who present with coronavirus disease 2019-associated myocardial dysfunction.

Individuals aged 1-64 years with documented congenital heart defects at healthcare encounters, five U.S. surveillance sites, 2011-2013.

BACKGROUND: Many individuals born with congenital heart defects (CHD) survive to adulthood. However, population estimates of CHD beyond early childhood are limited in the U.S. OBJECTIVES: To estimate the percentage of individuals aged 1-to-64 years at five U.S. sites with CHD documented at a healthcare encounter during a three-year period and describe their characteristics. METHODS: Sites conducted population-based surveillance of CHD among 1 to 10-year-olds (three sites) and 11 to 64-year-olds (all five sites) by linking healthcare data. Eligible cases resided in the population catchment areas and had one or more healthcare encounters during the surveillance period (January 1, 2011-December 31, 2013) with a CHD-related ICD-9-CM code. Site-specific population census estimates from the same age groups and time period were used to assess percentage of individuals in the catchment area with a CHD-related ICD-9-CM code documented at a healthcare encounter (hereafter referred to as CHD cases). Severe and non-severe CHD were based on an established mutually exclusive anatomic hierarchy. RESULTS: Among 42,646 CHD cases, 23.7% had severe CHD and 51.5% were male. Percentage of CHD cases among 1 to 10-year-olds, was 6.36/1,000 (range: 4.33-9.96/1,000) but varied by CHD severity [severe: 1.56/1,000 (range: 1.04-2.64/1,000); non-severe: 4.80/1,000 (range: 3.28-7.32/1,000)]. Percentage of cases across all sites in 11 to 64-year-olds was 1.47/1,000 (range: 1.02-2.18/1,000) and varied by CHD severity [severe: 0.34/1,000 (range: 0.26-0.49/1,000); non-severe: 1.13/1,000 (range: 0.76-1.69/1,000)]. Percentage of CHD cases decreased with age until 20 to 44 years and, for non-severe CHD only, increased slightly for ages 45 to 64 years. CONCLUSION: CHD cases varied by site, CHD severity, and age. These findings will inform planning for the needs of this growing population.

Text Message Medication Adherence Reminders Automated and Delivered at Scale Across Two Institutions: Testing the Nudge System: Pilot Study.

BACKGROUND: Medication refill behavior in patients with cardiovascular diseases is suboptimal. Brief behavioral interventions called Nudges may impact medication refill behavior and can be delivered at scale to patients using text messaging. METHODS: Patients who were prescribed and filled at least one medication for hypertension, hyperlipidemia, diabetes, atrial fibrillation, and coronary artery disease were identified for the pilot study. Patients eligible for the pilot (N=400) were enrolled with an opportunity to opt out. In phase I of the pilot, we tested text message delivery to 60 patients. In phase II, we tested intervention feasibility by identifying those with refill gap of ≥7 days and randomized them to intervention or control arms. Patients were texted Nudges and assessed whether they refilled their medications. RESULTS: Of 400 patients sent study invitations, 56 (14%) opted out. In phase I, we successfully delivered text messages to 58 of 60 patients and captured patient responses via text. In phase II, 207 of 286 (72.4%) patients had a medication gap ≥7 days for one or more cardiovascular medications and were randomized to intervention or control. Enrolled patients averaged 61.7 years old, were primarily male (69.1%) and White (72.5%) with hypertension being the most prevalent qualifying condition (78.7%). There was a trend towards intervention patients being more likely to refill at least 1 gapping medication (30.6% versus 18.0%; P=0.12) and all gapping medications (17.8% versus 10.0%; P=0.27). CONCLUSIONS: It is possible to set up automated processes within health care delivery systems to identify patients with gaps in medication adherence and send Nudges to facilitate medication refills. Text message Nudges could potentially be a feasible and effective method to facilitate medication refills. A large multi-site randomized trial to determine the impact of text-based Nudges on overall CVD morbidity and mortality is now underway to explore this further.

Outcomes in hospitalisations of women with Turner syndrome compared to women without Turner syndrome.

OBJECTIVE: To evaluate outcomes in patients with Turner Syndrome, especially those with cardiac conditions, compared to those without Turner syndrome. DESIGN: Retrospective cohort study utilising hospitalisation data from 2006 to 2012. Conditional logistic regression models are used to analyse outcomes of interest: all-cause mortality, increased length of stay, and discharge to home. PARTICIPANTS: We identified 2978 women with Turner syndrome, matched to 11,912 controls by primary diagnosis. RESULTS: Patients with Turner syndrome were more likely to experience inpatient mortality (odds ratio 1.44, 95% confidence interval 1.02-2.02, p = 0.04) and increased length of stay (OR 1.31, CI 1.18-1.46, p = 0.03) than primary diagnosis matched controls, after adjusting for age, race, insurance status, and Charlson comorbidity index. Patients with Turner syndrome were 32% less likely to be discharged to home (OR 0.68, CI 0.60-0.78, p < 0.001). When restricting the sample of patients to those admitted with a cardiac diagnosis, the likelihood of mortality (OR 3.10, CI 1.27-7.57, p = 0.01) and prolonged length of stay (OR 1.42, CI 1.03-1.95, p = 0.03) further increased, while the likelihood of discharge to home further decreased (OR 0.55, CI 0.38-0.80, p = 0.001) in Turner syndrome compared to primary diagnosis matched controls. Specifically, patients with congenital heart disease were more likely to have prolonged length of stay (OR: 1.53, CI 1.18-2.00, p = 0.002), but not increased mortality or decreased discharge to home. CONCLUSIONS: Hospitalised women with Turner syndrome carry a higher risk of adverse outcomes even when presenting otherwise similarly as controls, an important consideration for those treating them in these settings.

Patients with bicuspid aortic valves may be associated with infra-hisian conduction disease requiring pacemakers.

BACKGROUND: Bicuspid aortic valves (BAVs) are associated with accelerated valvular dysfunction. Increasing rates of conduction system disease are seen in patients with calcific tricuspid aortic valves (TAVs). However, little is known regarding the extent of conduction disorders in BAV patients. We sought to determine the extent of infra-hisian conduction pathology among patients with BAVs undergoing EP studies. METHODS: We prospectively analyzed patients presenting to the EP laboratory from 2006 to 2017 at our institution. Thirty-three BAV patients had measured HV intervals. Each individual was matched by age and gender to two control patients. Clinical characteristics were collected and compared, and patients followed for outcomes. RESULTS: The BAV cohort had a mean age of 47.8 ± 17.2 years (range 19-76 years). Indications for referral to the EP lab in the BAV cohort included SVT ablation (n = 16), VT ablation (n = 10), and EP study for syncope, pre-syncope, or palpitations (n = 29). Patients with BAVs had a mean HV interval of 58.7 ms ± 18.6 ms, compared to a mean of 47.2 ms ± 9.6 ms for controls (p value = 0.0001). Over a 10-year follow-up period, 9 BAV patients (27%) went on to require permanent pacing compared to 6 patients (9%) in the control group (p value = 0.03). CONCLUSION: Compared to patients with TAVs presenting for EP evaluation, individuals with BAVs have longer HV intervals and a significantly increased requirement for pacemaker therapy over long-term follow-up. Closer monitoring of progressive conduction system disease in BAV patients may be warranted.

Associations Between Socioeconomic Context and Congenital Heart Disease Related Outcomes in Adolescents and Adults.

Little is known about the relation between socioeconomic factors and health outcomes in adults and adolescents with congenital heart defects (CHD). Population-level data from the Colorado CHD surveillance system from 2011 to 2013 was used to examine the association between area deprivation and outcomes including hospitalizations, emergency department visits, cardiac procedures, all-cause and cardiac-related mortality, and major adverse cardiac events. Socioeconomic context was measured by the Area Deprivation Index at census tract level. Missing race/ethnicity was imputed using the Bayesian Improved Surname Geocoding algorithm. Generalized linear models were utilized to examine health disparities across deprivation quintiles after adjusting for insurance type, race/ethnicity, age, gender, urbanicity, and CHD severity in 5,748 patients. Cases residing in the most deprived quintile had 51% higher odds of inpatient admission, 74% higher odds of emergency department visit, 41% higher odds of cardiac surgeries, and 45% higher odds of major adverse cardiac events compared with cases in the least deprived quintile. Further, rates of hospitalizations, emergency department admissions, and cardiac surgeries were elevated in the most deprived compared with the least deprived quintile. Mortality was not significantly different across quintiles. In conclusion, findings suggest significant health equity issues for adolescent and adults with CHD based on area-based deprivation.

Population-level surveillance of congenital heart defects among adolescents and adults in Colorado: Implications of record linkage.

BACKGROUND: The objective was to describe the design of a population-level electronic health record (EHR) and insurance claims-based surveillance system of adolescents and adults with congenital heart defects (CHDs) in Colorado and to evaluate the bias introduced by duplicate cases across data sources. METHODS: The Colorado CHD Surveillance System ascertained individuals aged 11-64 years with a CHD based on International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic coding between 2011 and 2013 from a diverse network of health care systems and an All Payer Claims Database (APCD). A probability-based identity reconciliation algorithm identified duplicate cases. Logistic regression was conducted to investigate bias introduced by duplicate cases on the relationship between CHD severity (severe compared to moderate/mild) and adverse outcomes including all-cause mortality, inpatient hospitalization, and major adverse cardiac events (myocardial infarction, congestive heart failure, or cerebrovascular event). Sensitivity analyses were conducted to investigate bias introduced by the sole use or exclusion of APCD data. RESULTS: A total of 12,293 unique cases were identified, of which 3,476 had a within or between data source duplicate. Duplicate cases were more likely to be in the youngest age group and have private health insurance, a severe heart defect, a CHD comorbidity, and higher health care utilization. We found that failure to resolve duplicate cases between data sources would inflate the relationship between CHD severity and both morbidity and mortality outcomes by ~15%. Sensitivity analyses indicate that scenarios in which APCD was excluded from case finding or relied upon as the sole source of case finding would also result in an overestimation of the relationship between a CHD severity and major adverse outcomes. DISCUSSION: Aggregated EHR- and claims-based surveillance systems of adolescents and adults with CHD that fail to account for duplicate records will introduce considerable bias into research findings. CONCLUSION: Population-level surveillance systems for rare chronic conditions, such as congenital heart disease, based on aggregation of EHR and claims data require sophisticated identity reconciliation methods to prevent bias introduced by duplicate cases.

Transplant and mechanical circulatory support in patients with adult congenital heart disease.

Advances in surgery and pediatric care over the past decades have achieved improved survival for children born with congenital heart disease (CHD) and have produced a large, growing population of patients with adult congenital heart disease (ACHD). Heart failure has emerged as the leading cause of death and a major cause of morbidity among the ACHD population, while as little evidence supports the efficacy of guideline-directed medical therapies in this population. It is increasingly important that clinicians caring for these patients understand how to utilize mechanical circulatory support (MCS) in ACHD. In this review, we summarize the data on transplantation and MCS in the ACHD-heart failure population and provide a framework for how ACHD patients may benefit from advanced heart failure therapies like transplantation and MCS.

Nationwide Frequency, Sequential Trends, and Impact of Co-morbid Mental Health Disorders on Hospitalizations, Outcomes, and Healthcare Resource Utilization in Adult Congenital Heart Disease.

Despite the growing prevalence of adult congenital heart disease (ACHD), data on trends in prevalence of mental health disorders (MHD) among patients with ACHD remain limited. The National Inpatient Sample (2007 to 2014) was queried to identify the frequency and trends of MHD among ACHD hospitalizations (stratification by age, sex, and race); demographics and co-morbidities for ACHD cohorts, with (MHD+) versus without MHD (MHD-); the rate and trends of all-cause in-hospital mortality, disposition, mean length of stay, and hospitalization charges among both cohorts. A total of 11,709 (13.8%, mean age: 49.1 years, 56.0% females, 78.7% white) out of 85,029 ACHD patient encounters had a coexistent MHD (anxiety, depression, mood disorder, or psychosis). ACHD-MHD+ cohort was more often admitted nonelectively (38.1% vs 32.8%, p <0.001) and had a higher frequency of cardiac/extra-cardiac co-morbidities. The trends in prevalence of coexistent MHD increased from 10.3% to 17.5% (70% relative increase) from 2007 to 2014 with a consistently higher prevalence among females (from 13% to 20.3%) compared to males (from 7.6% to 15.5%) (ptrend <0.001). The hospitalization trends with MHD increased in whites (12.1% to 19.8%) and Hispanics (5.9% to 12.7%). All-cause mortality was lower (0.7% vs 1.1%, p = 0.002) in ACHD-MHD+; however, mean length of stay (∼5.7 vs 4.9 days, p <0.001) was higher without significant difference in charges ($97,710 vs $96,058, p = 0.137). ACHD-MHD+ cohort was less often discharged routinely (declining trend) and more frequently transferred to other facilities and required home healthcare (rising trends). In conclusion, this study reveals increasing trends of MHD, healthcare resource utilization and a higher frequency of co-morbidities in patients with ACHD.
