Self-care is advocated as a method of improving outcomes from heart failure (HF), the final common pathway for several prevalent illnesses, including hypertension and coronary artery disease. HF is widespread in aging populations across the world.1 The burden of HF is manifested in poor quality of life (QOL)2,3 and early mortality.4 In addition, there are >3 million ambulatory care and emergency department visits5 and well over 1 million hospitalizations for HF in the United States annually,6 which contributes to the exorbitant costs associated with HF. Much of this healthcare utilization is thought to be preventable if patients engage in consistent self-care.7,8 This scientific statement seeks to highlight concepts and evidence important to the understanding and promotion of self-care in persons with HF. Specifically, the document describes what is known about (1) the self-care behaviors required of HF patients, (2) factors that make self-care challenging for patients, (3) interventions that promote self-care, and (4) the effect of self-care on HF outcomes. The review ends with evidence-based recommendations for clinicians and direction for future research. Self-care is defined as a naturalistic decision-making process that patients use in the choice of behaviors that maintain physiological stability (symptom monitoring and treatment adherence) and the response to symptoms when they occur.9 The term naturalistic decision making is used to describe how people make decisions in real-world settings. Naturalistic decision makers focus on process rather than outcomes, make decisions based on the situation, let the context influence their decision-making processes, and base practical decisions on the information available at the moment.10 In HF, self-care maintenance requires following the advice of providers to take medications, eat a low-sodium diet, exercise, engage in preventive behaviors, and actively monitor themselves for signs and symptoms. Self-care management refers to decision making in …

Background— The arrhythmia burden in tetralogy of Fallot, types of arrhythmias encountered, and risk profile may change as the population ages. Methods and Results— The Alliance for Adult Research in Congenital Cardiology (AARCC) conducted a multicenter cross-sectional study to quantify the arrhythmia burden in tetralogy of Fallot, to characterize age-related trends, and to identify associated factors. A total of 556 patients, 54.0% female, 36.8±12.0 years of age were recruited from 11 centers. Overall, 43.3% had a sustained arrhythmia or arrhythmia intervention. Prevalence of atrial tachyarrhythmias was 20.1%. Factors associated with intraatrial reentrant tachycardia in multivariable analyses were right atrial enlargement (odds ratio [OR], 6.2; 95% confidence interval [CI], 2.8 to 13.6), hypertension (OR, 2.3; 95% CI, 1.1 to 4.6), and number of cardiac surgeries (OR, 1.4; 95% CI, 1.2 to 1.6). Older age (OR, 1.09 per year; 95% CI, 1.05 to 1.12), lower left ventricular ejection fraction (OR, 0.93 per unit; 95% CI, 0.89 to 0.96), left atrial dilation (OR, 3.2; 95% CI, 1.5 to 6.8), and number of cardiac surgeries (OR, 1.5; 95% CI, 1.2 to 1.9) were jointly associated with atrial fibrillation. Ventricular arrhythmias were prevalent in 14.6% and jointly associated with number of cardiac surgeries (OR, 1.3; 95% CI, 1.1 to 1.6), QRS duration (OR, 1.02 per 1 ms; 95% CI, 1.01 to 1.03), and left ventricular diastolic dysfunction (OR, 3.3; 95% CI, 1.5 to 7.1). Prevalence of atrial fibrillation and ventricular arrhythmias markedly increased after 45 years of age. Conclusions— The arrhythmia burden in adults with tetralogy of Fallot is considerable, with various subtypes characterized by different profiles. Atrial fibrillation and ventricular arrhythmias appear to be influenced more by left- than right-sided heart disease.

Many children born with complex childhood illnesses that historically caused early death are now surviving into adulthood with the expectation of leading meaningful and productive lives. They will ultimately need to transition their care from pediatric to adult-centered care. Unfortunately, in the absence of structured programs to guide this transition, there is often delayed or inappropriate care, improper timing of the transfer of care, and undue emotional and financial stress on the patients, their families, and the healthcare system. At its worst, and as frequently happens now, patients are lost to appropriate follow-up. In fact, the number of adults with congenital heart disease (CHD) in the United States is rising exponentially and now exceeds 1 000 000.1,–,7 At least half of these patients may have complex CHD. Fewer than 30% of adults with CHD are seen by appropriate specialized providers. Fewer than 15% of these patients, who are seen in specialty adult CHD (ACHD) clinics, have CHD that is classified as severe.8 Thus, adolescents with CHD constitute a growing population of individuals for whom a well-planned and well-executed “transition process” is essential. The goals of a formal transition program are to prepare young adults for transfer of care. It should provide uninterrupted health care that is patient centered, age and developmentally appropriate, flexible, and comprehensive. It should include age-appropriate education about medical conditions and promote skills in communication, decision making, self-care, and self-advocacy.9,–,13 It should foster greater personal and medical independence and a greater sense of control over health, healthcare decisions, and psychosocial environment. The ultimate goal of a transition program is to optimize the quality of life (QOL), life expectancy, and future productivity of young patients.14 We acknowledge that the development of ideal transition programs is a …

Ruey-Kang R. Chang; Michelle Gurvitz; Sandra Rodriguez

OBJECTIVES To evaluate the rate and the clinical and demographic characteristics of missed diagnosis of critical congenital heart disease (CCHD). DESIGN Population-based retrospective study of 1989-2004 California statewide death registry data. SETTING California. PARTICIPANTS The study cohort consisted of 898 infants who died of CCHD at 1 to 364 days of age who either did not undergo surgery or had an unknown surgery status. From all patients who met these initial criteria, we examined (1) whether autopsies were performed and autopsy results were used to establish the cause of death, (2) whether autopsies were performed but the results were not used to establish a cause of death, and (3) whether infants with hypoplastic left heart syndrome (HLHS) were potentially receiving comfort care. MAIN OUTCOME MEASURES Missed and possibly late diagnosis of CCHD. RESULTS Among 152 infants with a missed CCHD diagnosis, the median age at death was 13.5 days. More than 50% of patients with a missed CCHD diagnosis (n = 78) died at home or in the hospital emergency department. The most common diagnoses were HLHS and coarctation of aorta. There were an average of 10 patients with missed CCHD diagnoses and 20 patients with late diagnoses in California per year. The total annual number of patients with missed or late diagnoses decreased in 1989-1999 and remained unchanged in 2000-2004. CONCLUSIONS Up to 30 infants per year died of a missed or possibly late diagnosis of CCHD in California. Most deaths due to a missed diagnosis were from HLHS and coarctation of the aorta. Because the median age at death was younger than 2 weeks, a careful cardiovascular evaluation for left heart obstructive CHD should be performed during the first postdischarge visit to a pediatricians office at 3 to 5 days of age.

Left ventricular (LV) systolic dysfunction has been observed in patients with repaired tetralogy of Fallot (TOF), although its clinical associations are unknown. Adults with repaired TOF were identified from 11 adult congenital heart disease centers. Clinical history was reviewed. Patients with pulmonary atresia were excluded. Echocardiograms were reanalyzed to estimate LV ejection fraction. LV function was defined as normal (LV ejection fraction ≥ 55%) or mildly (45% to 54%), moderately (35% to 44%), or severely (< 35%) decreased. Right ventricular (RV) and LV dimensions and Doppler parameters were remeasured. Function of all valves was qualitatively scored. Of 511 patients studied, LV systolic dysfunction was present in 107 (20.9%, 95% confidence interval 17.4 to 24.5). Specifically, 74 (14.4%) had mildly decreased and 33 (6.3%) had moderately to severely decreased systolic function. Presence of moderate to severe LV dysfunction was associated with male gender, LV enlargement, duration of shunt before repair, history of arrhythmia, QRS duration, implanted cardioverter-defibrillator, and moderate to severe RV dysfunction. Severity or duration of pulmonary regurgitation was not different. In conclusion, LV systolic dysfunction was found in 21% of adult patients with TOF and was associated with shunt duration, RV dysfunction, and arrhythmia.

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.

Objective Heart failure (HF) is one of the most important complications in pregnant women with heart disease, causing maternal and fetal mortality and morbidity. Methods This is an international observational registry of patients with structural heart disease during pregnancy. Sixty hospitals in 28 countries enrolled 1321 women between 2007 and 2011. Pregnant women with valvular heart disease, congenital heart disease, ischaemic heart disease, or cardiomyopathy could be included. Main outcome measures were onset and predictors of HF and maternal and fetal death. Results In total, 173 (13.1%) of the 1321 patients developed HF, making HF the most common major cardiovascular complication during pregnancy. Baseline parameters associated with HF were New York Heart Association class ≥3, signs of HF, WHO category ≥3, cardiomyopathy or pulmonary hypertension. HF occurred at a median time of 31 weeks gestation (IQR 23–40) with the highest incidence at the end of the second trimester (34%) or peripartum (31%). Maternal mortality was higher in patients with HF (4.8% in patients with HF and 0.5% in those without HF p<0.001). Pre-eclampsia was strongly related to HF (OR 7.1, 95% CI 3.9 to 13.2, p<0.001). Fetal death and the incidence of preterm birth were higher in women with HF compared to women without HF (4.6% vs 1.2%, p=0.001; and 30% vs 13%, p=0.001). Conclusions HF was the most common complication during pregnancy, and occurred typically at the end of the second trimester, or after birth. It was most common in women with cardiomyopathy or pulmonary hypertension and was strongly associated with pre-eclampsia and an adverse maternal and perinatal outcome.

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.

OBJECTIVES The objective of this study was to document the prevalence of chronic venous insufficiency (CVI) and its associated factors in adults with Fontan physiology. BACKGROUND As the population of adults with complex congenital heart disease and Fontan physiology increases, so does the occurrence of highly morbid and mortal outcomes, including heart failure and thromboembolism. The presence of abnormal peripheral hemodynamic conditions in this population and their potential contribution to adverse outcomes is not well known. The primary objective of this study was to document the prevalence of CVI in adults with Fontan physiology. METHODS A total of 159 adults with Fontan physiology from 7 adult congenital heart centers were prospectively assessed for lower extremity CVI, with the assignment of clinical, etiological, anatomical, and pathophysiological classification grades, and compared with age-matched and sex-matched controls. Leg photographs were independently reassessed to confirm interobserver reliability. RESULTS The prevalence of CVI was significantly greater in the Fontan population (60%; 95% confidence interval [CI]: 52% to 68%) compared with healthy controls (32%; 95% CI: 15% to 54%) (p = 0.008). Strikingly, the prevalence of severe CVI (clinical, etiological, anatomical, and pathophysiological grade > or = 4) was significantly higher in the Fontan group (22%; 95% CI: 16% to 29%) versus the healthy controls (0%; 95% CI: 0% to 14%) (p = 0.005). In a multivariate analysis, several factors were independently associated with severe CVI, including increased numbers of catheterizations with groin venous access, lower extremity itching, and deep venous thrombosis. CONCLUSIONS CVI is common in adult patients with congenital heart disease with Fontan physiology. The contribution of abnormal peripheral hemodynamic conditions to comorbidities, including thromboembolism and heart failure, and interventions to improve peripheral hemodynamic conditions require further exploration.
