RESUMEN
AIMS: To examine factors related to excess mortality in a cohort of adults with congenital heart disease (CHD). METHODS AND RESULTS: We conducted a survival analysis using prospective data of 3311 adults with CHD [50.5% males, median age at entry 22.5 years (IQR 18-39), median follow-up time 10.5 years (IQR: 4.4-18)]. Survival status of each patient was further verified by cross checking with the Spanish National Death Index. During a total follow-up of 37608 person-years, 336 (10%) patients died. Annual death rate was 0.89% and standardized mortality ratio (SMR) 2.64 [95% confidence interval (CI) 2.3-3.0; P < 0.001]. Median age at death estimated by left-truncated Kaplan-Meier method was 75.1 years (95% CI 73-77). Survival was reduced compared with the general population whatever their level of complexity, repair status, or underlying CHD. Independent risk factors for excess mortality, including cyanosis, univentricular physiology, genetic disorders, ventricular dysfunction, residual haemodynamic lesions and acquired late complications, among others, were identified by left-truncated Cox regression model. SMR was 5.22 (95% CI 4.5-6.0; P < 0.001) and median age at death 55.6 years (95% CI 50-61) for 996 patients (30%) with at least one risk factor. In contrast, SMR was 1.14 (95% CI 0.9-1.5; P = 0.19) and median age at death 83.7 years (95% CI 82-87) in 2315 patients (70%) with no risk factors. CONCLUSIONS: Clinical parameters, such as anatomical features, haemodynamic sequelae, or acquired complications, were independent predictors of excess mortality in adults with CHD. Survival of individuals with no risk factors did not differ from the reference population.

OBJECTIVES: To develop, calibrate, test and validate a logistic regression model for accurate risk prediction of sudden cardiac death (SCD) and non-fatal sudden cardiac arrest (SCA) in adults with congenital heart disease (ACHD), based on baseline lesion-specific risk stratification and individual's characteristics, to guide primary prevention strategies. METHODS: We combined data from a single-centre cohort of 3311 consecutive ACHD patients (50% male) at 25-year follow-up with 71 events (53 SCD and 18 non-fatal SCA) and a multicentre case-control group with 207 cases (110 SCD and 97 non-fatal SCA) and 2287 consecutive controls (50% males). Cumulative incidences of events up to 20 years for specific lesions were determined in the prospective cohort. Risk model and its 5-year risk predictions were derived by logistic regression modelling, using separate development (18 centres: 144 cases and 1501 controls) and validation (two centres: 63 cases and 786 controls) datasets. RESULTS: According to the combined SCD/SCA cumulative 20 years incidence, a lesion-specific stratification into four clusters-very-low (<1%), low (1%-4%), moderate (4%-12%) and high (>12%)-was built. Multivariable predictors were lesion-specific cluster, young age, male sex, unexplained syncope, ischaemic heart disease, non-life threatening ventricular arrhythmias, QRS duration and ventricular systolic dysfunction or hypertrophy. The model very accurately discriminated (C-index 0.91; 95% CI 0.88 to 0.94) and calibrated (p=0.3 for observed vs expected proportions) in the validation dataset. Compared with current guidelines approach, sensitivity increases 29% with less than 1% change in specificity. CONCLUSIONS: Predicting the risk of SCD/SCA in ACHD can be significantly improved using a baseline lesion-specific stratification and simple clinical variables.

AIMS: Patients with adult congenital heart disease (ACHD) are a potentially vulnerable patient cohort in case of COVID-19. Some cardiac defects may be associated with a poor COVID-19 outcome. Risk estimation in ACHD is currently based on expert opinion. The aim of this study was to collect clinical outcome data and to identify risk factors for a complicated course of COVID-19 in patients with ACHD. METHODS: Twenty-five ACHD centres in nine European countries participated in the study. Consecutive patients with ACHD diagnosed with COVID-19 presenting to one of the participating centres between 27 March and 6 June 2020 were included. A complicated disease course was defined as hospitalisation for COVID-19 requiring non-invasive or invasive ventilation and/or inotropic support, or a fatal outcome. RESULTS: Of 105 patients with a mean age of 38±13 years (58% women), 13 had a complicated disease course, of whom 5 died. In univariable analysis, age (OR 1.3, 95% CI 1.1 to 1.7, per 5 years), ≥2 comorbidities (OR 7.1, 95% CI 2.1 to 24.5), body mass index of >25 kg/m2 (OR 7.2, 95% CI 1.9 to 28.3) and cyanotic heart disease (OR 13.2, 95% CI 2.5 to 68.4) were associated with a complicated disease course. In a multivariable logistic regression model, cyanotic heart disease was the most important predictor (OR 60.0, 95% CI 7.6 to 474.0). CONCLUSIONS: Among patients with ACHD, general risk factors (age, obesity and multiple comorbidities) are associated with an increased risk of complicated COVID-19 course. Congenital cardiac defects at particularly high risk were cyanotic lesions, including unrepaired cyanotic defects or Eisenmenger syndrome.
RESUMEN
BACKGROUND: The impact of gender and aging on relative survival and causes of death in adults with congenital heart disease (ACHD) are not well known. METHODS: Single center observational longitudinal study of 3311 consecutive ACHD (50.5% males) followed up to 25years. Patients were divided by the age at last follow-up into three groups: <40, 40-65 and >65years old. Their vital status was verified by crosschecking the Spanish National Death Index. Regression model for relative survival from reference population was performed. Cause of death was classified according to the International Classification of Diseases (ICD-10). Patients who died from cardiovascular (CV) causes were further investigated on a case-by-case basis. RESULTS: During a cumulative follow-up time of 37,608 person-years 336 patients died (10%). Age-adjusted relative survival in females was significantly worse than in males (hazard ratio [HR] 1.25; 95% confidence interval [CI] 1.0-1.6; p=0.046), and sex-adjusted relative survival improved across the three group of ages (HR 0.98; 95% CI 0.97-0.99; p<0.001). There was a temporal decline of CV deaths with aging in both genders (p<0.001). The leading cause of CV death was heart failure but sudden death prevailed in subjects <40years (p=0.004). While sudden death progressively declined with aging heart failure significantly increased (p<0.001). CONCLUSIONS: Women with CHD fare worse than men. There are a decline in CV deaths and a major temporal shift in the causes of CV deaths with aging. Heart failure surpasses sudden death as the primary cause of death in survivors over 40years.

The incidence and risk factors for prosthetic pulmonary valve failure (PPVF) should be considered when determining optimal timing for pulmonary valve replacement (PVR) in asymptomatic patients with congenital heart disease (CHD). The cumulative freedom for reintervention due to PPVF after 146 PVR in 114 patients with CHD was analyzed. Six potential risk factors (underlying cardiac defect, history of palliative procedures, number of previous cardiac interventions, hemodynamic indication for PVR, type of intervention, and age at intervention) were analyzed using Cox proportional hazard modeling. Receiver operating characteristic (ROC) curves were used for discrimination. Internal validation in patients with tetralogy of Fallot was also performed. Median age at intervention was 23 years. There were 60 reinterventions due to PPVF (41%). Median event-free survival was 14 years (95% confidence interval [CI] 12 to 16 years). The only independent risk factor was the age at intervention (hazard ratio [HR] 0.93, 95% CI 0.90 to 0.97; p = 0.001; area under the ROC curve 0.95, 95% CI 0.92 to 0.98; p <0.001). The best cut-off point was 20.5 years. Freedom from reintervention for PPVF 15 years after surgery was 70% when it was performed at age >20.5 years compared with 33% when age at intervention was <20.5 years (p = 0.004). Internal validation in 102 PVR in patient cohort with tetralogy of Fallot (ROC area 0.98, 95% CI 0.96 to 1.0; p <0.001) was excellent. In conclusion, age at intervention is the main risk factor of reintervention for PPVF. The risk of reintervention is 2-fold when PVR is performed before the age of 20.5 years.

Many adult survivors of repaired congenital heart disease (CHD) are at premature risk of death. Sudden cardiac arrest (SCA) is 1 of the leading causes of death but little is known about determinants for SCA in adults with repaired lesions. We sought to determine incidence and risk factors for SCA in a study population of 936 adults with previously repaired CHD who had completed follow-up at a single tertiary center during a mean period of 9 ± 7 years. Mean age at first examination in our institution was 21 ± 7 years. Diagnostic categories included tetralogy of Fallot (216), coarctation of the aorta (157), transposition complexes (99), single ventricle (55), and other CHD (409). During a total follow-up of 8,387 person-years, 22 patients (2.6 per 1,000 person-years) presented with SCA. Incidence of SCA varied widely between specific lesions; the highest incidence was observed in transposition complexes (10 per 1,000 person-years). Independent predictors of SCA were retrospectively identified using multivariate Cox proportional hazard modeling. Age at initial examination and severely impaired subaortic ventricular systolic function were independent risk factors for SCA (severe subaortic ventricular systolic dysfunction, adjusted hazard ratio 29, 95% confidence interval 11 to 72, p <0.001). SCA occurred in 23% of patients with severe subaortic ventricular systolic dysfunction versus 0.7% of patients with nonsevere decreased subaortic ventricular function (p <0.001). In conclusion, severe subaortic ventricular systolic dysfunction is a dominant multivariate predictor of SCA in an unselected population of adult survivors after surgery for CHD. Our data support the consideration of primary prevention strategies in these patients.

The long-term outcome of patients with congenitally corrected transposition of the great arteries is mainly determined by progressive morphologically tricuspid valve regurgitation, heart block, atrial arrhythmias, and/or systemic ventricular dysfunction. Situs abnormalities have been reported in ≤34% of cases, but whether clinical differences exist between a situs inversus and situs solitus arrangement has not yet been studied. The clinical records of 38 adults with congenitally corrected transposition of the great arteries (mean age 40 ± 15 years) followed for a mean period of 7.4 years were reviewed. Of these 38 patients, 8 presented with situs inversus and 30 with situs solitus. No significant differences were found between the 2 groups in age, gender, ventricular septal defect, pulmonary tract stenosis, previous surgical repair, or duration of follow-up. However, none of the patients with situs inversus presented with an Ebstein-like anomaly of the morphologically tricuspid valve and none developed nonoperative-related complete atrioventricular block compared to 15 (50%; p = 0.013) and 11 (42%; p = 0.032) of the patients with situs solitus, respectively. At follow-up, 2 patients with situs inversus (25%) presented with sustained atrial arrhythmia, severe tricuspid regurgitation, or severe systemic right ventricular systolic dysfunction compared to 22 (73%) of 30 those with situs solitus (p = 0.034). No patient with situs inversus presented with cardiac death or severe heart failure compared to 12 (40%) of 30 with situs solitus (p = 0.038). In conclusion, Ebstein-like anomaly or spontaneous complete atrioventricular block are rare in patients with congenitally corrected transposition of the great arteries with situs inversus, and late complications are uncommon. The long-term outcome of patients with situs inversus was significantly better than that for patients with situs solitus.

The actual incidence of ascending aorta complications (AACs) in adults with bicuspid aortic valve (BAV) and the role of associated coarctation of the aorta (COA) as an independent risk factor for AACs remain unknown. From the Adult Congenital Heart Disease database at La Paz Hospital, 631 patients in whom a BAV was diagnosed by echocardiography or surgical inspection since December 1989 were identified. These patients were then further subdivided into 2 groups according to the presence of an associated COA. AACs included aortic aneurysms (ascending aorta > or =55 mm) and aortic dissection, rupture, or perforation. Patients with a BAV and COA had a greater prevalence of AACs (8.0%) than those with an isolated BAV (3.7%; p = 0.037). The coexistence of COA was the only significant predictor of AACs (odds ratio 4.7, 95% confidence interval 1.5 to 15; p = 0.01). From the total patient group with a BAV, the clinical and echocardiographic data were reviewed for 341 patients without an AAC at baseline (97 with and 244 without COA) who had undergone serial examinations >1 year apart. The median follow-up was 7 years (interquartile range 3.5 to 10.2; total 2,436 patient-years). A new AAC occurred in 13 patients (0.5/100 patient-years). The incidence of AACs was 1.3/100 patient-years in the COA group versus 0.2/100 patient-years in the non-COA group (hazard ratio 7.5, 95% confidence interval 2.0 to 28, p = 0.002). All acute aortic events (dissection or rupture) at follow-up occurred in patients with a BAV and COA. In conclusion, the long-term incidence of AACs in patients with isolated BAV is low, but patients with BAV and associated COA are at increased risk.
