RESUMEN
INTRODUCTION AND OBJECTIVES: The role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in the risk prediction of patients with systemic right ventricles (sRV) is not well defined. The aim of this study was to analyze the prognostic value of NT-proBNP in patients with an sRV. METHODS: The prognostic value of NT-proBNP was assessed in 98 patients from the SERVE trial. We used an adjusted Cox proportional hazards model, survival analysis, and c-statistics. The composite primary outcome was the occurrence of clinically relevant arrhythmia, heart failure, or death. Correlations between baseline NT-proBNP values and biventricular volumes and function were assessed by adjusted linear regression models. RESULTS: The median age [interquartile range] at baseline was 39 [32-48] years and 32% were women. The median NT-proBNP was 238 [137-429] ng/L. Baseline NT-proBNP concentrations were significantly higher among the 20 (20%) patients developing the combined primary outcome compared with those who did not (816 [194-1094] vs 205 [122-357]; P=.003). In patients with NT-proBNP concentrations> 75th percentile (> 429 ng/L), we found an exponential increase in the sex- and age-adjusted hazard ratio for the primary outcome. The prognostic value of NT-proBNP was comparable to right ventricular ejection fraction and peak oxygen uptake on exercise testing (c-statistic: 0.71, 0.72, and 0.71, respectively). CONCLUSIONS: In patients with sRVs, NT-proBNP concentrations correlate with sRV volumes and function and may serve as a simple tool for predicting adverse outcomes.
RESUMEN
BACKGROUND: The determinants and prognostic value of high-sensitivity cardiac troponin T (hs-cTnT) among patients with a systemic right ventricle are largely unknown. METHODS AND RESULTS: Ninety-eight patients from the randomized controlled SERVE (Effect of Phosphodiesterase-5 Inhibition With Tadalafil on Systemic Right Ventricular Size and Function) trial were included. The correlation between baseline hs-cTnT concentrations and biventricular volumes and function quantified by cardiac magnetic resonance or cardiac multirow detector computed tomography was assessed by adjusted linear regression models. The prognostic value of hs-cTnT was assessed by adjusted Cox proportional hazards models, survival analysis, and concordance statistics. The primary outcome was time to the composite of clinically relevant arrhythmia, hospitalization for heart failure, or all-cause death. Median age was 39 (interquartile range, 32-48) years, and 32% were women. Median hs-cTnT concentration was 7 (interquartile range, 4-11) ng/L. Coefficients of determination for the relationship between hs-cTnT concentrations and right ventricular end-systolic volume index and right ventricular ejection fraction (RVEF) were +0.368 (P=0.046) and -0.381 (P=0.018), respectively. The sex- and age-adjusted hazard ratio for the primary outcome of hs-cTnT at 2 and 4 times the reference level (5 ng/L) were 2.89 (95% CI, 1.14-7.29) and 4.42 (95% CI, 1.21-16.15), respectively. The prognostic performance quantified by the concordance statistics for age- and sex-adjusted models based on hs-cTnT, right ventricular ejection fraction, and peak oxygen uptake predicted were comparable: 0.71% (95% CI, 0.61-0.82), 0.72% (95% CI, 0.59-0.84), and 0.71% (95% CI, 0.59-0.83), respectively. CONCLUSIONS: Hs-cTnT concentration was significantly correlated with right ventricular ejection fraction and right ventricular end-systolic volume index in patients with a systemic right ventricle. The prognostic accuracy of hs-cTnT was comparable to that of right ventricular ejection fraction and peak oxygen uptake predicted.

BACKGROUND: In patients with transposition of the great arteries and an arterial switch operation (TGA-ASO) right ventricular outflow tract (RVOT) obstruction is a common complication requiring one or more RVOT interventions. OBJECTIVES: We aimed to assess cardiopulmonary exercise capacity and right ventricular function in patients stratified for type of RVOT intervention. METHODS: TGA-ASO patients (≥16 years) were stratified by type of RVOT intervention. The following outcome parameters were included: predicted (%) peak oxygen uptake (peak VO2), tricuspid annular plane systolic excursion (TAPSE), tricuspid Lateral Annular Systolic Velocity (TV S'), right ventricle (RV)-arterial coupling (defined as TAPSE/RV systolic pressure ratio), and N-terminal proBNP (NT-proBNP). RESULTS: 447 TGA patients with a mean age of 25.0 (interquartile range (IQR) 21-29) years were included. Patients without previous RVOT intervention (n = 338, 76%) had a significantly higher predicted peak VO2 (78.0 ± 17.4%) compared to patients with single approach catheter-based RVOT intervention (73.7 ± 12.7%), single approach surgical RVOT intervention (73.8 ± 28.1%), and patients with multiple approach RVOT intervention (66.2 ± 14.0%, p = 0.021). RV-arterial coupling was found to be significantly lower in patients with prior catheter-based and/or surgical RVOT intervention compared to patients without any RVOT intervention (p = 0.029). CONCLUSIONS: TGA patients after a successful arterial switch repair have a decreased exercise capacity. A considerable amount of TGA patients with either catheter or surgical RVOT intervention perform significantly worse compared to patients without RVOT interventions.

AIMS: Bicuspid aortic valve (BAV) is a common congenital condition that is frequently associated with aortic stenosis (AS) and aortic regurgitation (AR), as well as aortic aneurysms, but specific outcome data are scarce. The present study sought to assess outcomes in a large cohort of consecutive patients with BAV. METHODS AND RESULTS: A total of 581 consecutive patients (median age 29 years, 157 female) with BAV were included in the study and followed prospectively in a heart valve clinic follow-up programme. The overall survival rate after 10 years was 94.5%. During follow-up, 158 patients developed an indication for surgery. Event-free survival rates were 97%, 94%, 87%, and 73% at 1, 2, 5, and 10 years, respectively. In the multivariable analysis, event rates were independently predicted by AS [subdistribution hazard ratio (SHR) 2.3 per degree of severity], AR (SHR 1.5 per degree of severity), baseline aortic dilatation ≥ 40â mm (SHR 1.9), and age (SHR 1.3) (P < 0.001). CONCLUSION: BAV disease is associated with a high rate of cardiac events, but state-of-the-art care results in good survival with low rates of infective endocarditis, aortic dissection, and sudden death. Incremental degrees of AS and regurgitation, the presence of aortic dilatation, and age are predictive of cardiac events.

AIMS: In adults with congenital heart disease and systemic right ventricles, progressive right ventricular systolic dysfunction is common and is associated with adverse outcomes. Our aim was to assess the impact of the phosphodiesterase-5-inhibitor tadalafil on right ventricular systolic function. METHODS AND RESULTS: This was a double-blind, randomized, placebo-controlled, multicentre superiority trial (NCT03049540) involving 100 adults with systemic right ventricles (33 women, mean age: 40.7 ± 10.7 years), comparing tadalafil 20 mg once daily versus placebo (1:1 ratio). The primary endpoint was the change in right ventricular end-systolic volume after 3 years of therapy. Secondary endpoints were changes in right ventricular ejection fraction, exercise capacity and N-terminal pro-B-type natriuretic peptide concentration. Primary endpoint assessment by intention to treat analysis at 3 years of follow-up was possible in 83 patients (42 patients in the tadalafil group and 41 patients in the placebo group). No significant changes over time in right ventricular end-systolic volumes were observed in the tadalafil and the placebo group, and no significant differences between treatment groups (3.4 ml, 95% confidence interval -4.3 to 11.0, p = 0.39). No significant changes over time were observed for the pre-specified secondary endpoints for the entire study population, without differences between the tadalafil and the placebo group. CONCLUSIONS: In this trial in adults with systemic right ventricles, right ventricular systolic function, exercise capacity and neuro-hormonal activation remained stable over a 3-year follow-up period. No significant treatment effect of tadalafil was observed. Further research is needed to find effective treatment for improvement of ventricular function in adults with systemic right ventricles.

Patients with severe asymptomatic primary mitral regurgitation (MR) can be safely managed with an active surveillance strategy. Left atrial (LA) size is affected by MR severity, left ventricular function and is also associated with the risk of atrial fibrillation and may be an integrative parameter for risk stratification. The present study sought to determine the predictive value of LA size in a large series of asymptomatic patients with severe MR. 280 consecutive patients (88 female, median age 58 years) with severe primary MR and no guideline-based indications for surgery were included in a follow-up program until criteria for mitral surgery were reached. Event-free survival was determined and potential predictors of outcome were assessed. Survival free of any indication for surgery was 78% at 2 years, 52% at 6 years, 35% at 10 years and 19% at 15 years, respectively. Left atrial (LA) diameter was the strongest independent echocardiographic predictor of event-free survival with incremental predictive value for the thresholds of 50, 60 and 70 mm, respectively. In a multivariable analysis that encompassed age at baseline, previous history of atrial fibrillation, left ventricular end systolic diameter), LA diameter, sPAP > 50 mmHg and year of inclusion, LA diameter was the strongest independent echocardiographic predictor of event-free survival (adjusted HR = 1.039, p < 0.001). LA size is a simple and reproducible predictor of outcome in asymptomatic severe primary MR. In particular, it may help to identify patients who may benefit from early elective valve surgery in heart valve centers of excellence.

BACKGROUND: Valve repair is the procedure of choice for congenital aortic valve disease. With increasing experience, the surgical armamentarium broadened from simple commissurotomy to more complex techniques. We report our 30-year experience with pediatric aortic valve repair. METHODS: A retrospective chart review of all patients aged less than 18 years who underwent aortic valve repair from May 1985 to April 2020 was conducted. Mortality was cross-checked with the national health insurance database (96% complete mortality follow-up in April 2020). Primary study endpoints were survival and incidence of reoperations. RESULTS: From May 1985 until April 2020, 126 patients underwent aortic valve repair at a median age of 1.8 years (interquartile range, 0.2-10). Early mortality was 5.6% (7 of 126). All early deaths occurred in neonates with critical aortic stenosis undergoing commissurotomy. No early deaths were observed after 2002. Kaplan-Meier estimated survival was 90.8% (95% CI, 84.0-94.8) at 10 years, 86.9% (95% CI, 78.7-92.2) at 20 years, and 83.5% (95% CI, 71.7-90.6) at 30 years. The cumulative incidence of aortic valve replacement was 37% (95% CI, 27.7-46.3) at 10 years, 62.2% (95% CI, 50.1-72.1) at 20 years, and 67.4% (51.2-79.2) at 30 years. Nine patients had undergone re-repair of the aortic valve. The majority of valve replacements were Ross procedures. CONCLUSIONS: Our results support a repair-first strategy for patients with congenital heart disease and underline that aortic valve reconstruction can be a successful long-term solution. Longevity did not differ between aortic valve commissurotomy and complex aortic valve reconstruction.

Background: At the beginning of the COVID-19 pandemic, professionals in charge of particularly vulnerable populations, such as adult congenital heart disease (ACHD) patients, were confronted with difficult decision-making. We aimed to assess changes in risk stratification and outcomes of ACHD patients suffering from COVID-19 between March 2020 and April 2021. Methods and results: Risk stratification among ACHD experts (before and after the first outcome data were available) was assessed by means of questionnaires. In addition, COVID-19 cases and the corresponding patient characteristics were recorded among participating centres. Predictors for the outcome of interest (complicated disease course) were assessed by means of multivariable logistic regression models calculated with cluster-robust standard errors. When assessing the importance of general and ACHD specific risk factors for a complicated disease course, their overall importance and the corresponding risk perception among ACHD experts decreased over time. Overall, 638 patients (n = 168 during the first wave and n = 470 during the subsequent waves) were included (median age 34 years, 52% women). Main independent predictors for a complicated disease course were male sex, increasing age, a BMI >25 kg/m2, having ≥2 comorbidities, suffering from a cyanotic heart disease or having suffered COVID-19 in the first wave vs. subsequent waves. Conclusions: Apart from cyanotic heart disease, general risk factors for poor outcome in case of COVID-19 reported in the general population are equally important among ACHD patients. Risk perception among ACHD experts decreased during the course of the pandemic.
RESUMEN
Objectives: Subvalvular aortic stenosis (SAS) can occur as discrete or tunnel-like obstruction of the left ventricular outflow tract and as progressive disease often leads to aortic valve regurgitation. We report our 30-year single-center experience after surgical repair of SAS. Methods: A retrospective chart review of all patients aged < 18 years, who underwent surgical repair of SAS from May 1985 to April 2020, was conducted. Mortality was cross-checked with the national health insurance database (93.8% complete mortality follow-up in April 2020). Survival and competing risks analysis were used to analyze the primary endpoints survival and incidence of reoperations. Results: From May 1985 until April 2020 103 patients (median age 5.5 years) underwent surgical repair of SAS. Survival was 90.8% at 10 years and 88.7% at 20 and 30 years. Age < 1 year at time of surgery, Shone's complex, mitral stenosis and concomitant mitral valve surgery were associated with mortality. The cumulative incidence of reoperation for SAS was 21.6% at 10 years, 28.2% at 20 and 30 years. The incidence of reoperation for SAS did not differ between the myectomy, membrane resection and combined myectomy and membrane resection groups. The cumulative incidence of reoperation on the aortic valve was 13.5% at 20 years. Conclusion: Recurrence rate of SAS is not to be neglected, though surgical repair of subaortic stenosis has good long-term results. Patients who needed a combined membrane resection and septal myectomy are not more prone to recurrence than patients who underwent solitaire myectomy or membrane resection.
RESUMEN
Background: As a preventive procedure, minimizing periprocedural risk is crucially important during left atrial appendage closure (LAAC). Methods: We included consecutive patients receiving LAAC at nine centres and assessed the relationship between baseline characteristics and the acute procedural outcome. Major procedural complications were defined as all complications requiring immediate invasive intervention or causing irreversible damage. Logistic regression was performed and included age and left-ventricular function. Furthermore, the association between acute complications and long-term outcomes was evaluated. Results: A total of 405 consecutive patients with a median age of 75 years (37% female) were included. 47% had a history of stroke. Median CHA2DS2-VASc score was 4 (interquartile range, 3−5) and the median HAS-BLED score was 3 (2−4). Major procedural complications occurred in 7% of cases. Low haemoglobin (OR 0.8, 95% CI 0.65−0.99 per g/dL, p = 0.040) and end-stage kidney disease (OR 13.0, CI 2.5−68.5, p = 0.002) remained significant in multivariate analysis. Anaemia (haemoglobin < 12 and < 13 g/dL in female and male patients) increased the risk of complications 2.2-fold. Conclusions: The major complication rate was low in this high-risk patient population undergoing LAAC. End-stage kidney disease and low baseline haemoglobin were independently associated with a higher major complication rate.
RESUMEN
BACKGROUND: In recent years, patient-reported outcomes (PROs) have received increasing prominence in cardiovascular research and clinical care. An understanding of the variability and global experience of PROs in adults with congenital heart disease (CHD), however, is still lacking. Moreover, information on epidemiological characteristics and the frailty phenotype of older adults with CHD is minimal. The APPROACH-IS II study was established to address these knowledge gaps. This paper presents the design and methodology of APPROACH-IS II. METHODS/DESIGN: APPROACH-IS II is a cross-sectional global multicentric study that includes Part 1 (assessing PROs) and Part 2 (investigating the frailty phenotype of older adults). With 53 participating centers, located in 32 countries across six continents, the aim is to enroll 8000 patients with CHD. In Part 1, self-report surveys are used to collect data on PROs (e.g., quality of life, perceived health, depressive symptoms, autonomy support), and explanatory variables (e.g., social support, stigma, illness identity, empowerment). In Part 2, the cognitive functioning and frailty phenotype of older adults are measured using validated assessments. DISCUSSION: APPROACH-IS II will generate a rich dataset representing the international experience of individuals in adult CHD care. The results of this project will provide a global view of PROs and the frailty phenotype of adults with CHD and will thereby address important knowledge gaps. Undoubtedly, the project will contribute to the overarching aim of improving optimal living and care provision for adults with CHD.

We report two cases of paradoxical cerebral embolism in adults with congenital heart disease (ACHD) with residual atrial shunt lesions, a 59 year-old male patient with partial detachment of a surgical ASD closure patch, and a 57 year-old male patient with Ebstein's anomaly and a large patent foramen ovale. Considering these mechanisms and the increasing incidence of venous thrombosis with age, a higher prevalence of paradoxical embolism in ACHD patients with residual atrial shunts may be suspected. Regular follow-up of patients with ACHD remains important throughout life even in seemingly stable lesions.
RESUMEN
BACKGROUND: Adults with transposition of the great arteries (d-TGA) after the arterial switch operation (ASO) are an evolving cohort in adult cardiology. We aimed to analyze cardiac function and cardiac events after transition to the adult clinic in Switzerland. MATERIALS AND METHODS: Adults with prior ASO enrolled in the Swiss Adult Congenital HEart disease Registry (SACHER) were included. We analyzed initial cardiac anatomy, surgical history, residual lesions and cardiac function at the time of inclusion, as well as cardiac events during follow-up. Patients were classified as complex (with ventricular septal defect) or simple (with intact interventricular septum) d-TGA. RESULTS: The cohort included 149 patients (99 simple d-TGA, 50 complex d-TGA; age 21±3 years; 71% male, follow-up 27 [15-46] months). Prior to inclusion, patients with complex d-TGA had undergone more interventions related to the left ventricular outflow tract (16% vs. 3%, p = 0.01). Functional and cardiovascular status were similar between the groups. Eleven patients (7%) had a total of 19 cardiac events (5 complications and 14 re-interventions) during follow-up. Patients with complex d-TGA had more cardiac-related complications compared to those with simple d-TGA (8% vs. 1%, p = 0.03). The frequency of re-interventions was not statistically different between the two groups (12% vs. 4%, p = 0.07). During follow-up, an increase in QRS duration was observed. Other parameters of cardiac function remained unchanged. CONCLUSION: The majority of adult ASO patients have normal functional class and cardiac function. Complex anatomy and residual lesions play a key role when regarding the occurrence of cardiac-related complications during follow-up. The role of QRS prolongation over time needs to be investigated further.

Background: The long-term outcome of adults with repaired total anomalous pulmonary venous connection (TAPVC) is poorly documented. Therefore, the present study aims to provide current clinical data on adult survivors with repaired TAPVC focusing on arrhythmia. Methods: Clinical and imaging data (prevalence and type of arrhythmias, symptoms, surgical and medical treatment, echocardiographic and cardiac magnetic resonance haemodynamic parameters) were retrospectively collected from 8 European centres and compared between patients with and without arrhythmias. Results: Fifty-seven patients were included (age 20 [16-67] years [female 28, 49%]). At the last follow-up, that is, 21 (8-51) years after surgery, 79% and 93% of patients were free of symptoms and cardiac medication, respectively. The prevalence of late arrhythmias was 21%; 9 (16%) patients showed intra-atrial re-entrant tachycardia (IART) and 2 (4%) ventricular arrhythmias. Patients with IART were older (P = 0.018) and 4 (7%) required antiarrhythmic medication. Three patients (5%) underwent an electrophysiological study, and another 3 (5%) underwent pacemaker implantation within 36 months after surgical correction, which were removed in 2 patients after 7 years. Early postoperative arrhythmias (P = 0.005), right ventricular dilatation (P = 0.003), and valvulopathy (P = 0.009) were more often present in patients with late IART. Conclusions: Adult survivors after isolated-TAPVC repair presented a high prevalence of arrhythmias. Age, right ventricular dilatation, early arrhythmias, and valvular lesions are risk factors for IART. Long-term follow-up is important as some of these currently asymptomatic patients will probably develop arrhythmias in the future.
Contexte: Les résultats de santé à long terme chez les adultes ayant subi la correction d'un retour veineux pulmonaire anormal total (RVPAT) sont mal connus. Notre étude vise donc à recueillir des données cli-niques au sujet des patients ayant subi cette intervention et ayant survécu jusqu'à l'âge adulte, en particulier pour ce qui est des arythmies. Méthodologie: Les données d'observation clinique et d'imagerie (la prévalence et le type d'arythmies, les symptômes, les traitements chirurgicaux et médicaux, et les paramètres hémodynamiques obtenus par échographie et par résonance magnétique cardiaque) ont été recueillies de façon rétrospective dans huit centres européens et comparées selon que les patients présentaient ou non une arythmie. Résultats: Cinquante-sept patients ont été retenus (âge médian : 20 [16-67] ans; 28 [49 %] femmes). Au dernier suivi, soit 21 (8-51) ans après l'intervention chirurgicale, 79 % des patients ne présentaient pas de symptômes et 93 % des patients ne prenaient pas de médicaments pour des troubles cardiaques. La prévalence d'arythmies tardives s'élevait à 21 %; neuf patients (16 %) présentaient une tachycardie par réentrée intra-atriale (TRIA) et deux patients (4 %) présentaient des arythmies ventriculaires. Les patients qui présentaient une TRIA étaient plus âgés (P = 0,018) et quatre d'entre eux (7 %) devaient prendre des médicaments antiarythmiques. Trois patients (5 %) avaient subi des études électrophysiologiques et trois autres patients (5 %) avaient subi l'implantation d'un stimulateur cardiaque au cours des 36 mois suivant la correction chirurgicale; le stimulateur cardiaque a été retiré sept ans plus tard dans deux de ces cas. Les arythmies postopératoires précoces (P = 0,005), la dilation du ventricule droit (P = 0,003) et la valvulopathie (P = 0,009) étaient plus fréquentes chez les patients qui présentaient une TRIA tardive. Conclusions: La prévalence d'arythmies chez les patients survivant jusqu'à l'âge adulte après la correction isolée d'un RVPAT était élevée. L'âge, la dilation du ventricule droit, les arythmies précoces et les lésions valvulaires sont des facteurs de risque de TRIA. Il est important d'effectuer un suivi à long terme des patients ayant subi une RVPAT puisque certains d'entre eux, asymptomatiques pour le moment, présenteront sans doute des arythmies dans les années à venir.
RESUMEN
BACKGROUND AND PURPOSE: Patent foramen ovale (PFO)is associated with cryptogenic stroke, especially in young adults. Transcranial Doppler (TCD) ultrasound is used as a screening tool before transesophageal echocardiography (TEE). However, the use of Valsalva maneuver (VM) to identify a right-to-left-shunt underlies interindividual variability. Here, we aimed to assess whether a pressure-controlled standardization of VM is useful to estimate PFO size. METHODS: We included patients aged 18-80 years with a PFO according to TEE. Subjects underwent TCD with microembolic signals (MES) counted under four pressure conditions (i.e., at rest, 15 mbar, 40 mbar, and maximum expiratory pressure). Findings were correlated with TEE-based PFO size. The predictive value of TCD at rest and VM-based TCD for PFO size estimation was assessed by stepwise multivariate linear regression models and multiple cross-tab-analyses. RESULTS: We screened 203 subjects after a cerebrovascular event, of which 78 (48 males [61.5%], median age 55 years [22-80]) with PFO were included. We found an association between MES count and expiratory pressure (p < .001). Predefined MES count categories at TCD pressure conditions correlated significantly with PFO size measured by TEE. We propose a PFO size estimation model based on TCD at rest and under VM, which classified PFO size correctly in 64.1% with the highest accuracy for small PFOs. CONCLUSION: Our data provide evidence that TCD with step-wise barometric standardization allows an estimation of PFO size with good accuracy. Though TCD will not replace TEE in future, this might be of clinical value in circumstances where TEE cannot be easily performed.

The vast majority of children with congenital heart disease (CHD) in high-income countries survive into adulthood. Further, paediatric cardiac services have expanded in middle-income countries. Both evolutions have resulted in an increasing number of CHD survivors. Expert care across the life span is necessitated. In adolescence, patients transition from being a dependent child to an independent adult. They are also advised to transfer from paediatrics to adult care. There is no universal consensus regarding how transitional care should be provided and how the transfer should be organized. This is even more challenging in countries with low resources. This consensus document describes issues and practices of transition and transfer of adolescents with CHD, accounting for different possibilities in high-, middle-, and low-income countries. Transitional care ought to be provided to all adolescents with CHD, taking into consideration the available resources. When reaching adulthood, patients ought to be transferred to adult care facilities/providers capable of managing their needs, and systems have to be in place to make sure that continuity of high-quality care is ensured after leaving paediatric cardiology.

OBJECTIVE: Adults with congenital heart disease (ACHD) may be at a higher risk of a fatal outcome in case of COVID-19. Current risk stratification among these patients relies on personal experience and extrapolation from patients with acquired heart disease. We aimed to provide an expert view on risk stratification while awaiting results from observational studies. METHODS: This study was an initiative of the EPOCH (European Collaboration for Prospective Outcome Research in Congenital Heart disease). Among nine European countries (Austria, Belgium, Denmark, France, Germany, Italy, the Netherlands, Spain and Switzerland), 24 experts from 23 tertiary ACHD centres participated in the survey. ACHD experts were asked to identify ACHD-specific COVID-19 risk factors from a list of potential outcome predictors and to estimate the risk of adverse COVID-19 outcomes in seven commonly seen patient scenarios. RESULTS: 82% of participants did not consider all ACHD patients at risk of COVID-19 related complications. There was a consensus on pulmonary arterial hypertension, Fontan physiology and cyanotic heart disease as risk factors for adverse outcomes. Among different ACHD scenarios, a patient with Eisenmenger syndrome was considered to be at the highest risk. There was a marked variability in risk estimation among the other potential outcome predictors and ACHD scenarios. CONCLUSIONS: Pulmonary arterial hypertension, Fontan palliation and cyanotic heart disease were widely considered as risk factors for poor outcome in COVID-19. However, there was a marked disparity in risk estimation for other clinical scenarios. We are in urgent need of outcome studies in ACHD suffering from COVID-19.

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
Aim: Peak oxygen uptake (peakVO2) is one of the strongest predictors of survival in patients with valvular heart disease. The purpose of this study was to determine whether endurance training improves peakVO2 and endurance capacity in patients with moderate-severe aortic and mitral valve disease. Methods: 30 patients with moderate-severe valvular heart disease were randomly assigned to 12 weeks of endurance training (TG) (n = 16) or standard care (SC) (n = 14). PeakVO2 and maximum working capacity (Wattmax) were assessed by cardiopulmonary exercise testing, as well as submaximal endurance test at 80% of peakVO2 at baseline and after 12 weeks. Results: There was a significant improvement in peakVO2 from 27.2 ± 5.9 ml/kg to 30.4 ± 6.3 ml/kg (P < 0.001) in TG compared to the SC (peakVO2 from 24.6 ± 4.4 to 24.7 ± 3.8) and in the Wattmax from 151.8 ± 41.0 Watt to 171.2 ± 49.7 Watt in the TG compared to the SC (152.9 ± 35.6 Watt to 149.2 ± 28.4 Watt). The endurance capacity increased significantly from 17.0 ± 9.4 min to 32.8 ± 16.8 min (p = 0.003) in the TG compared to the SC (11.7 ± 6.2 min to 11.2 ± 7.6 min). The heart rate during the endurance test decreased in the TG from 154 ± 14 b/min to 142 ± 20 b/min for the same workload. No changes could be seen in the SC. Conclusion: Endurance training in patients with moderate to severe valvular heart disease increased significantly the peakVO2 as well as the endurance capacity.
RESUMEN
BACKGROUND: Irrespective of initial treatment for congenital heart disease (CHD) in childhood, CHD is a lifelong condition, leaving patients at risk for complications. To support uninterrupted, age- and development-based care for young persons with CHD, guidelines and consensus papers emphasise the need for formal transition programmes, including transfer to adult CHD (ACHD) clinics. Here, we surveyed existing transfer and transition programmes in European ACHD centres. Our aims were to provide a contemporary view of transitional care for patients with CHD and to evaluate progress over the last decade. METHODS: We conducted a descriptive, cross-sectional survey in 96 ACHD centres in Europe. A specific survey form was developed that sampled the practices of transfer and/or transition. We used a transfer-transition index to quantify adherence to quality indicators of successful transfer and transition. RESULTS: Of the 96 ACHD centres, 40 (41.7%) offered a formal transition, and 85 (88.5%) had structured transfer from paediatric to ACHD care. Although 31% of the centres performed at a 'good' level on the transfer-transition index, only 4 (4.2%) satisfied all criteria. Most centres with a transition programme offered education and support through a dedicated transition specialist, who was a master's-prepared nurse in most centres. A minority of the ACHD centres offered a flexible transition process, starting at least two years before transfer. CONCLUSIONS: Nearly half of the included ACHD centres offered a formal transition programme, and almost 90% offered structured transfer. Despite some improvements since 2009, most of the programmes lacked an age- and development-based approach.
