AIMS: Previous studies in adult congenital heart disease (CHD) have demonstrated a link between renal dysfunction and mortality. However, the prognostic significance of renal dysfunction in CHD and decompensated heart failure (HF) remains unclear. We sought to assess the association between renal dysfunction and outcomes in adults with CHD presenting to our centre with acute HF between 2010 and 2021. METHODS AND RESULTS: This retrospective analysis focused on the association between renal dysfunction, pre-existing and on admission, and outcomes during and after the index hospitalization. Chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate <60 mL/min/1.73 m2. Cox regression analysis was used to identify the predictors of death post-discharge. In total, 176 HF admissions were included (mean age 47.7 ± 14.5 years, 43.2% females). One-half of patients had a CHD of great complexity, 22.2% had a systemic right ventricle, and 18.8% had Eisenmenger syndrome. Chronic kidney disease was present in one-quarter of patients. The median length of intravenous diuretic therapy was 7 (4-12) days, with a maximum dose of 120 (80-160) mg furosemide equivalents/day, and 15.3% required inotropic support. The in-hospital mortality rate was 4.5%. The 1- and 5-year survival rates free of transplant or ventricular assist device (VAD) post-discharge were 75.4% [95% confidence interval (CI): 69.2-82.3%] and 43.3% (95% CI: 36-52%), respectively. On multivariable Cox analysis, CKD was the strongest predictor of mortality or transplantation/VAD. Highly complex CHD and inpatient requirement of inotropes also remained predictive of an adverse outcome. CONCLUSION: Adult patients with CHD admitted with acute HF are a high-risk cohort. CKD is common and triples the risk of death/transplantation/VAD. An expert multidisciplinary approach is essential for optimizing outcomes.
Renal dysfunction was associated with more advanced disease, higher diuretic doses, and a longer hospital inpatient stay. Chronic kidney disease was common and tripled the risk of death, transplantation, or ventricular assist device. Renal dysfunction in adults with congenital heart disease and heart failure should prompt intensified monitoring, optimization of medical therapy, and collaborative management with renal physicians.

More than 90% of patients with congenital heart disease (CHD) are nowadays surviving to adulthood and adults account for over two-thirds of the contemporary CHD population in Western countries. Although outcomes are improved, surgery does not cure CHD. Decades of longitudinal observational data are currently motivating a paradigm shift toward a lifespan perspective and proactive approach to CHD care. The aim of this review is to operationalize these emerging concepts by presenting new constructs in CHD research. These concepts include long-term trajectories and a life course epidemiology framework. Focusing on a precision health, we propose to integrate our current knowledge on the genome, phenome, and environome across the CHD lifespan. We also summarize the potential of technology, especially machine learning, to facilitate longitudinal research by embracing big data and multicenter lifelong data collection.

Aims: The New York Heart Association functional classification (NYHA class) is often used to describe the functional capacity of adults with congenital heart disease (ACHD), albeit with limited evidence on its validity in this heterogeneous population. We aimed to validate the NYHA functional classification in ACHD by examining its relation to objective measures of limitation using cardiopulmonary exercise testing (CPET) and mortality. Methods and results: This study included all ACHD patients who underwent a CPET between 2005 and 2015 at the Royal Brompton, in whom functional capacity was graded according to the NYHA classification. Congenital heart diagnoses were classified according to the Bethesda score. Time to all-cause mortality from CPET was recorded in all 2781 ACHD patients (mean age 33.8 ± 14.2 years) enrolled in the study. There was a strong relation between NYHA class and peak oxygen consumption (peak VO2), ventilation per unit in carbon dioxide production (VE/VCO2) slope and the Bethesda classification (P < 0.0001). Although a large number of 'asymptomatic' (NYHA class 1) patients did not achieve a 'normal' peak VO2, the NYHA class was a strong predictor of mortality, with an 8.7-fold increased mortality risk in class 3 compared with class 1 (hazard ratio 8.68, 95% confidence interval: 5.26-14.35, P < 0.0001). Conclusion: Despite underestimating the degree of limitation in some ACHD patients, NYHA classification remains a valuable clinical tool. It correlates with objective measures of exercise and the severity of underlying cardiac disease, as well as mid- to long-term mortality and should, thus, be into incorporated the routine assessment and risk stratification of these patients.

OBJECTIVE: Abnormal body mass index (BMI) is associated with higher mortality in various cardiovascular cohorts. The prognostic implications of BMI in adults with congenital heart disease (ACHD) are unknown. We aim to assess the distribution of BMI and its association with symptoms and survival in the ACHD population. METHODS: We included 3069 ACHD patients (median age 32.6 years) under follow-up at our institution between 2001 and 2015. Patients were classified based on BMI as underweight (<18.5), normal weight (18.5-25), overweight (25-30) or obese (>30), and symptoms, exercise capacity and mortality were assessed. RESULTS: Overall, 6.2% of patients were underweight, 51.1% had normal weight, 28.2% were overweight and 14.6% were obese. Higher BMI values were associated with lower all-cause and cardiac mortality on univariable Cox analysis, and this effect persisted after adjustment for age, defect complexity, cyanosis and objective exercise capacity. Higher BMI was especially associated with better prognosis in symptomatic ACHD patients (HR 0.94 (95% CI 0.90 to 0.98), p=0.002) and those with complex underlying cardiac defects (HR 0.96 (95% CI 0.91 to 0.997), p=0.048) In patients with a complex cardiac defect who had repeated weight measurements, weight loss was also associated with a worse survival (HR 1.82 (95% CI 1.02 to 3.24), p=0.04). CONCLUSIONS: ACHD patients with a higher BMI had a lower mortality. The association between BMI and mortality was especially pronounced in symptomatic patients with complex underlying cardiac defects, suggesting that cardiac cachexia may play a role. Indeed, weight loss in complex ACHD patients was linked to an even higher mortality.

BACKGROUND: Brain natriuretic peptide (BNP) levels are elevated in patients with repaired Tetralogy of Fallot (rTOF), the clinical significance of which remains uncertain. METHODS AND RESULTS: Ninety consecutive adults (≥ 16 years) with rTOF (mean age 32.7 ± 11.3 years, 64% men) were prospectively recruited from a single tertiary centre, together with 15 age-matched and gender-matched controls. Patients with rTOF had elevated BNP (8.9 (5.9-14.6) vs 5.4 (2.2-7.5) pmol/L; p<0.01), and BNP activation was common even in asymptomatic patients. Also, atrial natriuretic peptide (6.9 (4.0-9.9) vs 3.3 (1.0-4.0) pmol/L; p<0.01), endothelin-1 (1.14 (0.94-1.48) vs 0.75 (0.44-0.93) pmol/L; p<0.01) and renin (55.0 (45.5-66.5) vs 18.6 (12.0-22.7) pmol/L; p<0.01) were elevated at baseline compared with controls. Interactions between BNP with endothelin-1, cardiothoracic ratio and right atrial area were evident. Eight deaths occurred over a median follow-up of 10 years. On Cox regression analysis, BNP emerged as a strong predictor of death (HR 1.16 per 10 pmol/L, 95% CI 1.05 to 1.29; p<0.01). Survival receiver operating curve analysis revealed an optimum cut-off of BNP ≥ 15 pmol/L (=52 pg/mL), above which BNP was related to significantly increased mortality (HR 5.40, 95% CI 1.29 to 22.6; p<0.01); absolute mortality at 5 years 19% vs 3% in patients with BNP ≤ 15 pmol/L. BNP was also a predictor of sustained arrhythmia (HR 2.06 per 10 pmol/L, 95% CI 1.32 to 3.21; p<0.05). CONCLUSIONS: Neurohormonal activation is present in adults with rTOF including asymptomatic patients. BNP level ≥ 15 pmol/L is associated with a fivefold increased risk of death. These data suggest that BNP measurement in patients with rTOF should be incorporated in the periodic risk stratification assessment of these patients under lifelong follow-up.

OBJECTIVES: To investigate survival in patients with Eisenmenger syndrome based on a systematic review of the literature and reanalysis of data. We specifically tested the hypothesis that previous publications have been subject to immortal time bias, confounding survival analyses. METHODS: A systematic review of the literature was performed to evaluate survival in treatment naïve patients with Eisenmenger syndrome and standardised mortality ratios were calculated. Furthermore, we used a contemporary cohort of 219 treatment naïve patients with Eisenmenger syndrome from the own institution as a comparison group. RESULTS: Overall, 12 studies (published 1971-2013) were identified, including a total of 1131 patients. Only one study seemed to deal appropriately with immortal time bias in this setting. All other studies did not account for this effect, thus overestimating survival prospects of patients with Eisenmenger syndrome by up to 20â years. After accounting for this effect we found high standardised mortality ratios, a 10-year mortality rate approaching 30-40% and no evidence of superior survival prospects of current era patients compared with those seen in the 1970s, 1980s and 1990s. Only, a historical Eisenmenger-cohort from the 1950s/1960s had worse survival. CONCLUSIONS: The current analysis challenges the traditional view of benign survival prospects of patients with Eisenmenger syndrome. In addition, survival prospects do not seem to have considerably improved over the last decades in untreated patients. These results support a proactive treatment strategy including a more aggressive approach trying to avoid the development of the condition.
