European guidelines advocate a goal-oriented treatment approach in pulmonary arterial hypertension (PAH), based on a comprehensive risk assessment instrument, which has been validated in several PAH subgroups. We investigated its discriminatory ability, and explored tricuspid annular plane systolic excursion (TAPSE) and revised thresholds to improve its predictability within the adult congenital heart disease (CHD) population. In total, 223 adults (42±16 years, 66% female, 68% Eisenmenger) were enrolled from five European PAH-CHD expert centers. Patients were classified as \'Low\', \'Intermediate\', or \'High\' risk at baseline visit and at follow-up within 4-18 months. By the general PAH guidelines instrument, survival did not differ between the risk groups (P=n.s.), mostly due to skewed group distribution. Reclassifying patients using revised thresholds for N-terminal pro-brain natriuretic peptide (NT-proBNP) and 6-minute walk distance (6MWD) (i.e., \'Low\', \'Intermediate\', \'High\' as <500, 500-1400, >1400 ng/l and >400, 165-400 and <165 m, respectively) and use of TAPSE (\'Low\', \'Intermediate\', \'High\' as >20, 16-20 and <16mm) significantly improved discrimination between the risk groups both at baseline and follow-up (P=0.001, ROC increase from 0.648 to 0.701), reclassifying 64 (29%) patients. Irrespective of follow-up risk group, survival was better for patients with higher proportions of low-risk variables. Improvement to a \'Low-risk\' profile at a median of 9 months follow-up provided improved survival comparable to survival of patients who remained in the \'Low risk\' group. In conclusion, the external validity of general risk instrument for PAH appeared to be of limited discriminatory value in PAH-CHD patients. We propose a refined risk instrument with improved discrimination for PAH-CHD.

BACKGROUND: Guideline-directed heart failure therapy with angiotensin receptor blocker/neprilysin inhibitor (ARNi) and sodium-glucose transporter inhibitors (SGLT2i) has been incrementally beneficial in improving outcomes in heart failure patients.
OBJECTIVE: Evaluate the feasibility and efficacy of guideline-directed medical therapy (GDMT) in adults congenital heart disease (ACHD) patients.
METHODS: In a retrospective cohort study, ACHD patients with either New York Heart Association (NYHA) Class II symptoms or systemic ejection fraction (EF) <45%, optimized on a combination of beta-blocker (BB), ARNi, mineralocorticoid receptor antagonist (MRA) and SGLT2i were evaluated.
RESULTS: Forty-six patients with a mean age 42.6 ± 12.1 years prescribed GDMT were identified. Twenty-eight (61%) were male, 20 (43%) had a systemic right ventricle (RV) and 9 (20%) had single-ventricle physiology. Over the optimization period, 20 (43%) were sustained on ARNi and 42 (91%) on SGLT2i in addition to treatment with BB and MRA. Over a period of 45 weeks, echocardiography parameters for left ventricle (LV) ejection fraction (EF) (+7.5%, p = 0.006), systemic ventricle (SV) velocity time integral (VTI) (+1.9 cm, p = 0.012) and LV global longitudinal strain (GLS) (-2.5%, p = 0.005) improved when 3-4 medications were used versus 1-2 medications alone. The use of either ARNi or SGLT2i (+8.1%, p = 0.017) or in combination (+7.0%, p = 0.043) increased LVEF compared to the use of neither medication.
CONCLUSIONS: Combination GDMT is beneficial in improving myocardial characteristics in ACHD patients with systemic RV and LV.

BACKGROUND: Fontan physiology leads to chronic changes in other organ systems that may affect long-term survival and the success of heart transplantation. Inadequate assessment and treatment of the extra-cardiac effects of Fontan may contribute to poor outcomes. Severity-graded/ordinal consensus definitions of Fontan complications are lacking, which limits understanding of how Fontan-specific morbidity affects patients\' outcomes.
RESULTS: A panel of Fontan patient and physiology experts, including pediatric, adult congenital, heart failure, and critical-care cardiology as well as pediatric nephrology, hepatology and psychology, convened to develop definitions of Fontan complications. Definitions were created by using a severity-graded ordinal scale: grade 1, mild; grade 2, moderate; grade 3, severe; grade 4, disabling or life threatening. Following definition creation, a second panel of 21 experts in Fontan circulatory failure used a modified Delphi methodology to modify and vote on definitions until consensus (> 90% agreement without recommended further modification) was reached on final definitions. After 3 rounds of modifications and voting, consensus agreement was achieved on all Fontan-specific definitions. The defined complications and morbidities of Fontan include: anatomic Fontan pathway obstruction, cyanosis, systemic venous abnormalities resulting from venous insufficiency, atrial arrhythmia, ventricular arrhythmia, bradycardia, chronic pleural effusions, chronic ascites, protein-losing enteropathy, plastic bronchitis, hemoptysis and pulmonary hemorrhage, sleep apnea, Fontan-associated liver disease, portal and hepatic variceal disease, acute kidney injury affecting clinical treatment, polycythemia, thrombotic disease, recurrent or severe bacterial infection, skin atrophy, adrenal insufficiency, physical impact of previous stroke, mood/behavior disorder, and neurodevelopmental disorder.
CONCLUSIONS: Consensus and severity-graded definitions of Fontan-specific cardiac and extra-cardiac complications were achieved and are available for use in research. They will allow future robust analyses of Fontan patient outcomes.

Sports participation in patients with congenital heart disease is an evolving subject. The American Heart Association/American College of Cardiology released a set of guidelines that advise the type and level of sports participation based primarily on anatomical defects with secondary consideration given to hemodynamic effects. Recently, the European Association of Preventive Cardiology/European Society of Cardiology/Association for European Paediatric and Congenital Cardiology offered a contrasting approach to sports participation that is based on hemodynamic and electrophysiological profiles of each patient, regardless of anatomical consideration. These guidelines are drastically different in their approaches but do have some similarities. In this review, we compare both documents, focusing on the aim, population, classification of sports, and the methodology of making recommendations. This review aims to assist practicing cardiologists in integrating the available published data and recommendations when counseling patients for sports participation.

Patients with anomalous aortic origin of a coronary artery (AAOCA) require imaging to clarify the multiple potential anatomic sites of obstruction (fixed or dynamic). Once repaired, the pathway of blood to the myocardium must not encounter: (1) intrinsic ostial stenosis, (2) obstruction from compression or distortion near the commissure or the intercoronary pillar, (3) stenosis where the artery exits the aortic wall (due to an acutely angled \"take-off\"), (4) compression due to a pathway between the great vessels, (5) stenosis or compression along an intramural course, or (6) compression due to an intramuscular (intraseptal/intraconal) course. Detailed anatomic evaluation of each of these locations allows the surgeon to select an appropriate repair strategy, and each of these abnormal anatomic features should be \"matched\" with a particular surgical correction. We speculate that the most common surgical repair, unroofing with or without tacking, is often inadequate, as in isolation, it may not allow for correction with a large orifice from the appropriate sinus, without an interarterial course. While the evidence base is insufficient to call these recommendations formal guidelines, these recommendations should serve as a basis for further validity testing, and ultimate evolution to more granular guidelines on AAOCA management.

The American Heart Association and American College of Cardiology published practice guidelines for the management of adult congenital heart disease in 2018 and the European Society of Cardiology published analogous guidelines in 2020. Although there are broad areas of consensus between the 2 documents, there are important differences that impact patient management. This review discusses key areas of agreement and disagreement between the 2 guidelines, with discussion of possible reasons for disagreement and potential implications.

Adult congenital heart disease (ACHD) continues to rapidly increase worldwide. With an estimated 1.5 million adults with ACHD in the USA alone, there is a growing need for better education in the management of these complex patients and multiple knowledge gaps exist. This manuscript comprehensively reviewed the recent (2020) updated European Society of Cardiology Guidelines for the management of ACHD created by the Task Force for the management of adult congenital heart disease of the European Society of Cardiology, with perioperative implications for the adult cardiac anesthesiologist and intensivist who may be called upon to manage these complex patients.

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.
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).
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.
