Prevalence and predictors of gaps in care among adult congenital heart disease patients: HEART-ACHD (The Health, Education, and Access Research Trial)

OBJECTIVES The goal of this project was to quantify the prevalence of gaps in cardiology care, identify predictors of gaps, and assess barriers to care among adult congenital heart disease (adult CHD) patients. BACKGROUND Adult CHD patients risk interruptions in care that are associated with undesired outcomes. METHODS Patients (18 years of age and older) with their first presentation to an adult CHD clinic completed a survey regarding gaps in, and barriers to, care. RESULTS Among 12 adult CHD centers, 922 subjects (54% female) were recruited. A >3-year gap in cardiology care was identified in 42%, with 8% having gaps longer than a decade. Mean age at the first gap was 19.9 years. The majority of respondents had more than high school education and knew their heart condition. The most common reasons for gaps included feeling well, being unaware that follow-up was required, and complete absence from medical care. Disease complexity was predictive of a gap in care with 59% of mild, 42% of moderate, and 26% of severe disease subjects reporting gaps (p < 0.0001). Clinic location significantly predicted gaps (p < 0.0001), whereas sex, race, and education level did not. Common reasons for returning to care were new symptoms, referral from provider, and desire to prevent problems. CONCLUSIONS Adult CHD patients have gaps in cardiology care; the first lapse commonly occurred at age ∼19 years, a time when transition to adult services is contemplated. Gaps were more common among subjects with mild and moderate diagnoses and at particular locations. These results provide a framework for developing strategies to decrease gaps and address barriers to care in the adult CHD population.

Portal and centrilobular hepatic fibrosis in Fontan circulation and clinical outcomes

BACKGROUND The Fontan operation redirects venous blood flow directly to the pulmonary circulation in subjects with single ventricle anatomy. Congestive hepatopathy and cirrhosis have been described in subjects with Fontan circulation, but the prevalence of and predictors for liver disease remain unknown. METHODS We performed a retrospective study of liver histopathology in Fontan subjects who had liver biopsy or autopsy. All specimens were graded using a pre-determined protocol. Additional data were collected through chart review. Among 68 subjects, specimens were obtained at a median age of 23.2 years (range 5.0 to 52.7 years). Median time since Fontan was 18.1 years (range 1.2 to 32.7 years). RESULTS Centrilobular fibrosis was seen in every specimen, with 41.2% showing Grade 4 centrilobular fibrosis. Portal fibrosis was seen in 82.3% of specimens, with 14.7% showing cirrhosis. Megamitochondria were seen in 58.8% of specimens. Centrilobular fibrosis grade was greater in those with a dominant left or right ventricle than in those with a combined right and left systemic ventricle (p = 0.008). Portal fibrosis grade correlated with alkaline phosphatase (p = 0.04) and mode of biopsy (p = 0.02). Neither centrilobular fibrosis nor portal fibrosis grade was predictive of transplant-free survival or overall survival. CONCLUSIONS Individuals with Fontan physiology have a high prevalence of hepatic fibrosis. Signs and symptoms of liver disease did not predict histopathologic findings. Few risk factors for advanced disease were identified. Histopathology findings did not predict transplant-free survival. The role of liver biopsy in this population remains uncertain.

Shock-related anxiety and sexual function in adults with congenital heart disease and implantable cardioverter-defibrillators

BACKGROUND An increasing number of adults with congenital heart disease (CHD) require implantable cardioverter-defibrillators (ICDs), yet little is known about their impact on psychological well-being and sexual function. OBJECTIVE To assess shock-related anxiety in adults with CHD and its association with depression and sexual function. METHODS A prospective, multicenter, cross-sectional study was conducted on adult patients with CHD with (ICD(+)) and without (ICD(-)) ICDs. The Florida Shock Anxiety Scale was administered to patients with ICD(+) and the Beck Depression Inventory-II to all patients. Men completed the Sexual Health Inventory for Men, and women completed the Female Sexual Function Index. RESULTS A total of 180 adults with CHD (ICD(+): n = 70; ICD(-): n = 110; median age 32 years [interquartile range 27-40 years]; 44% women) were enrolled. The complexity of CHD was classified as mild in 32 (18%), moderate in 93 (52%), and severe in 54 (30%) subjects. In ICD recipients, a high level of shock-related anxiety was identified (Florida Shock Anxiety Scale score 16; interquartile range 12-23.5), which was slightly higher than the median score for ICD recipients in the general population (P = .057). A higher level of shock-related anxiety was associated with poorer sexual function scores in both men (Spearmans ρ =-.480; P<.001) and women (Spearmans ρ =-.512; P<.01). It was also associated with self-reported depressive symptomatology (Spearmans ρ = .536; P< .001). CONCLUSIONS Adults with CHD and ICDs demonstrate a high level of shock-related anxiety, which is associated with lower sexual functioning scores in men and women. These results underscore the need for increased clinical attention related to ICD-related shock anxiety and impaired sexual function in this population.

Liver health in adults with Fontan circulation: A multicenter cross-sectional study

Objectives: Liver disease is an important contributor to morbidity and mortality in patients after Fontan surgery. There has been no large‐scale survey of liver health in this population. We sought to explore the prevalence and predictors of liver disease in a multicenter cohort of adults with Fontan physiology. Methods: Subjects were recruited from 6 adult congenital heart centers. Demographics; clinical history; and laboratory, imaging, and histopathology data were obtained. Results: Of 241 subjects (median age 25.8 years [11.8‐59.4], median time since Fontan 20.3 years [5.4‐34.5]), more than 94% of those who underwent testing (208 of 221) had at least 1 abnormal liver‐related finding. All hepatic imaging (n = 54) and liver histology (n = 68) was abnormal. Subjects with abnormal laboratory values had higher sinusoidal fibrosis stage (2 vs 1, P = .007) and higher portal fibrosis stage (3 vs 1, P = .003) compared with those with all normal values. Low albumin correlated with lower sinusoidal fibrosis stage (1 vs 2; P = .02) and portal fibrosis stage (0 vs 3, P = .002); no other liver studies correlated with fibrosis. Regenerative nodules were seen on 33% of histology specimens. Conclusions: Regardless of modality, findings of liver disease are common among adults with Fontan circulation, even those appearing clinically well. Cirrhosis is present in up to one‐third of subjects. Correlations between hepatic fibrosis stage and clinical history or findings on noninvasive testing are few. Further research is needed to identify patients at risk for more severe liver disease and to determine the best methods for assessing liver health in this population.
