Objectives: This study aimed to determine the status of training of adult congenital heart disease (ACHD) cardiologists in Europe., Methods: A questionnaire was sent to ACHD cardiologists from 34 European countries., Results: Representatives from 31 of 34 countries (91%) responded. ACHD cardiology was recognised by the respective ministry of Health in two countries (7%) as a subspecialty. Two countries (7%) have formally recognised ACHD training programmes, 15 (48%) have informal (neither accredited nor certified) training and 14 (45%) have very limited or no programme. Twenty-five countries (81%) described training ACHD doctors 'on the job'. The median number of ACHD centres per country was 4 (range 0-28), median number of ACHD surgical centres was 3 (0-26) and the median number of ACHD training centres was 2 (range 0-28). An established exit examination in ACHD was conducted in only one country (3%) and formal certification provided by two countries (7%). ACHD cardiologist number versus gross domestic product Pearson correlation coefficient=0.789 (p<0.001)., Conclusion: Formal or accredited training in ACHD is rare among European countries. Many countries have very limited or no training and resort to 'train people on the job'. Few countries provide either an exit examination or certification. Efforts to harmonise training and establish standards in exit examination and certification may improve training and consequently promote the alignment of high-quality patient care., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Infective endocarditis (IE) remains major cause of morbidity and mortality in adult congenital heart disease (ACHD). Limited data exists on ACHD with IE in Central and South-Eastern European (CESEE) countries. The aim of this study is to characterize contemporary management and assess outcomes of ACHD with IE in CESEE region., Methods: Data on ACHD patients with IE from 9 tertiary centres in 9 different CESEE countries between 2015 and 2020 was included. Baseline demographics, clinical presentation, indication for surgery, outcomes, hospital and all-cause-1-year mortality were studied., Results: A total of 295 ACHD patients (mean age 40 ± 14 years) with IE were included. Median time from symptoms onset to establishing diagnosis was 25 (11-59) days. The majority of patients (203, 68.8%) received previous empiric oral antibiotic therapy. The highest incidence of IE was observed on native and left sided valves, 194(65.8%) and 204(69.2%), respectively. More than half had a vegetation size ≥10 mm (164, 55.6%); overall 138 (46.8%) had valve complications and 119 (40.3%) had heart failure. In-hospital mortality was 26 (8.8%)., Conclusion: There is clear delay in establishing IE diagnosis amongst ACHD patients in CESEE countries. Adequate diagnosis is hampered by common prescription of empiric antibiotics before establishing formal diagnosis. Hence, patients commonly present with associated complications requiring surgery. Hospital treatment and survival are, nevertheless, comparable to other Western European countries. Improved awareness and education of patients and medical profession regarding IE preventive measures, risks, signs, and symptoms are urgently needed. Empiric antibiotic prescription before blood cultures are taken must be omitted., Competing Interests: Declaration of Competing Interest No conflicts of interest., (Copyright © 2023 Elsevier B.V.

Aims: To examine the current status of care and needs of adult congenital heart disease (ACHD) services in the Central and South Eastern European (CESEE) region., Methods and Results: We obtained data regarding the national ACHD status for 19 CESEE countries from their ACHD representative based on an extensive survey for 2017 and/or 2018. Thirteen countries reported at least one tertiary ACHD centre with a median year of centre establishment in 2007 (interquartile range 2002-2013). ACHD centres reported a median of 2114 patients under active follow-up with an annual cardiac catheter and surgical intervention volume of 49 and 40, respectively. The majority (90%) of catheter or surgical interventions were funded by government reimbursement schemes. However, all 19 countries had financial caps on a hospital level, leading to patient waiting lists and restrictions in the number of procedures that can be performed. The median number of ACHD specialists per country was 3. The majority of centres (75%) did not have ACHD specialist nurses. The six countries with no dedicated ACHD centres had lower Gross Domestic Product per capita compared to the remainder (P = 0.005)., Conclusion: The majority of countries in CESEE now have established ACHD services with adequate infrastructure and a patient workload comparable to the rest of Europe, but important gaps still exist. ACHD care is challenged or compromised by limited financial resources, insufficient staffing levels, and reimbursement caps on essential procedures compared to Western Europe. Active advocacy and increased resources are required to address the inequalities of care across the continent., (© 2020 European Society of Cardiology.)

Objective: Patients with repaired tetralogy of Fallot (TOF) experience increased rates of mortality and morbidity in adulthood. This study was designed to identify risk factors for death and ventricular tachycardia (VT) in a large contemporary cohort of patients with repaired TOF., Methods: Subjects with repaired TOF from four large congenital heart centres in the USA, Canada and Europe were enrolled. Clinical, ECG, exercise, cardiac magnetic resonance (CMR) and outcome data were analysed., Results: Of the 873 patients (median age 24.4 years), 32 (3.7%) reached the primary outcome (28 deaths, 4 sustained VT; median age at outcome 38 years; median time from CMR to outcome 1.9 years). Cox proportional-hazards regression identified RV mass-to-volume ratio ≥ 0.3 g/mL (HR, 5.04; 95% CI 2.3 to 11.0; p<0.001), LV EF z score<-2.0 (HR, 3.34; 95% CI 1.59 to 7.01; p=0.001), and history of atrial tachyarrhythmia (HR, 3.65; 95% CI 1.75 to 7.62; p=0.001) as outcome predictors. RV dysfunction was predictive of the outcome similar to LV dysfunction. In subgroup analysis of 315 subjects with echocardiographic assessment of RV systolic pressure, higher pressure (HR 1.39; 95% CI 1.19 to 1.62; p<0.001) was associated with death and sustained VT independent of RV hypertrophy and LV dysfunction., Conclusions: RV hypertrophy, ventricular dysfunction and atrial tachyarrhythmias are predictive of death and sustained VT in adults with repaired TOF. These findings may inform risk stratification and the design of future therapeutic trials.

Objective: To investigate the prevalence and characteristics of cerebrovascular accidents (CVA) in a large population of adults with congenital heart disease (CHD)., Methods and Results: In a retrospective analysis of aggregated European and Canadian databases a total population of 23 153 patients with CHD was followed up to the age of 16-91 years (mean 36.4 years). Among them, 458 patients (2.0%) had one or more CVA, with an estimated event rate of 0.05% per patient-year. Permanent neurological sequelae were noted in 116 patients (25.3%). The prevalence of CVA in selected diagnostic categories was as follows: open atrial septal defect 93/2351 (4.0%); closed atrial or ventricular septal defect 57/4035 (1.4%); corrected tetralogy of Fallot 52/2196 (2.4%); Eisenmenger physiology 24/467 (5.1%); other cyanotic 50/215 (23.3%); mechanical prostheses (29/882 (3.3%). Associated conditions in patients with CVA were absence of sinus rhythm (25%), transvenous pacemakers (7%), endocarditis (2%), cardiac surgery (11%) and catheter intervention (2%), but with the exception of absent sinus rhythm these were not significantly more prevalent in patients with CVA., Conclusion: CVA are a major contributor to morbidity in this young population despite absence of classical cardiovascular risk factors. Although the prevalence of CVA in patients with CHD appears low, it is 10-100 times higher than expected in control populations of comparable age. Residua occur in a strong minority of patients. The subjects at highest risk are those patients with CHD with cyanotic lesions, in whom the prevalence is over 10-fold above the average.

Aims: To investigate the role of guidelines in structuring the clinical care for adult patients with congenital heart disease (CHD), and to assess adherence to the guidelines in Europe., Methods and Results: A selected number of current guidelines were chosen pertaining to operative procedures, investigations, and the use of medication ('interventions'). The source for this analysis was the database of the Euro Heart Survey on adult CHD, which contains retrospectively collected data on 4110 patients followed-up for a median of 5.1 years. For each guideline investigated, patients were selected from the database for whom the particular guideline was relevant. The selected cases were classified according to two criteria: was there an indication for the particular intervention and did the intervention take place? In this manner, cases of 'undue treatment' and 'insufficient treatment' were identified. Adherence to guidelines was found to be good in the case of operative procedures and prophylactic drug treatment. However, regarding diagnostic procedures there had been adherence to guidelines in only slightly more than half of the cases., Conclusion: Guidelines have an important role in the actual clinical care of adults with CHD. However, large outcome studies are needed to develop more precise guidelines.

Aims: To describe clinical and demographic characteristics at baseline of a European cohort of adults with congenital heart disease (CHD) and to assess mortality and morbidity in a 5 year follow-up period., Methods and Results: Data collected as part of the Euro Heart Survey on adult CHD was analysed. This entailed information transcribed from the files of 4110 patients diagnosed with one of eight congenital heart conditions ('defects'), who consecutively visited the outpatient clinics of one of the participating centres in 1998. The patients were included retrospectively and followed until the end of 2003 for a median follow-up of 5.1 years. Notwithstanding their overall relatively good functional class and low mortality over the follow-up period, a considerable proportion of the patients had a history of endocarditis, arrhythmias, or vascular events. There were major differences between the eight defects, both in morbidity and regarding specific characteristics. Outcomes were worst in cyanotic defects and in the Fontan circulation, but a considerable proportion of the other patients also suffer from cardiac symptoms. In particular, arrhythmias are common., Conclusion: The spectrum of adult CHD in Europe emerging from this survey is one of a predominantly young population with substantial morbidity but relatively low mortality in a 5 year period.
