To assess the characteristics, management, and survival of patients with multiple native valvular heart disease (VHD). Among the 5087 patients with ≥1 severe left-sided native VHD included in the EURObservational VHD II Survey (maximum 3-month recruitment period per centre between January and August 2017 with a 6-month follow-up), 3571 had a single left-sided VHD (Group A, 70.2%), 363 had one severe left-sided VHD with moderate VHD of the other ipsilateral valve (Group B, 7.1%), and 1153 patients (22.7%) had ≥2 severe native VHDs (left-sided and/or tricuspid regurgitation, Group C). Patients with multiple VHD (Groups B and C) were more often women, had greater congestive heart failure (CHF) and comorbidity, higher left atrial volumes and pulmonary pressures, and lower ejection fraction than Group A patients (all P ≤ 0.01). During the index hospitalization, 36.7% of Group A (n = 1312), 26.7% of Group B (n = 97), and 32.7% of Group C (n = 377) underwent valvular intervention (P < 0.001). Six-month survival was better for Group A than for Group B or C (both P < 0.001), even after adjustment for age, sex, body mass index, and Charlson index [hazard ratio (HR) 95% confidence interval (CI) 1.62 (1.10–2.38) vs. Group B and HR 95% CI 1.72 (1.32–2.25) vs. Group C]. Groups B and C had more CHF at 6 months than Group A (both P < 0.001). Factors associated with mortality in Group C were age, CHF, and comorbidity (all P < 0.010). Multiple VHD is common, encountered in nearly 30% of patients with left-sided native VHD, and associated with greater cardiac damage and leads to higher mortality and more heart failure at 6 months than single VHD, yet with lower rates of surgery. Characteristics, survival and management differences in patients with multiple valvular heart disease.

Introduction: Pulmonary hypertension (PH) is a common complication in patients with congenital heart disease (CHD), aggravating the natural, post-operative, or post-interventional course of the underlying anomaly. The various CHDs differ substantially in characteristics, functionality, and clinical outcomes among each other and compared with other diseases with pulmonary hypertension. Objective: To describe current management strategies and outcomes for adults with PH in relation to different types of CHD based on real-world data. Methods and results: COMPERA (Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension) is a prospective, international PH registry comprising, at the time of data analysis, >8200 patients with various forms of PH. Here, we analyzed a subgroup of 680 patients with PH due to CHD, who were included between 2007 and 2018 in 49 specialized centers for PH and/or CHD located in 11 European countries. At enrollment, the patients’ median age was 44 years (67% female), and patients had either pre-tricuspid shunts, post-tricuspid shunts, complex CHD, congenital left heart or aortic disease, or miscellaneous other types of CHD. Upon inclusion, targeted therapies for pulmonary arterial hypertension (PAH) included endothelin receptor antagonists, PDE-5 inhibitors, prostacyclin analogues, and soluble guanylate cyclase stimulators. Eighty patients with Eisenmenger syndrome were treatment-naïve. While at inclusion the primary PAH treatment for the cohort was monotherapy (70% of patients), with 30% of the patients on combination therapy, after a median observation time of 45.3 months, the number of patients on combination therapy had increased significantly, to 50%. The use of oral anticoagulants or antiplatelets was dependent on the underlying diagnosis or comorbidities. In the entire COMPERA-CHD cohort, after follow-up and receiving targeted PAH therapy (n = 511), 91 patients died over the course of a 5-year follow up. The 5-year Kaplan–Meier survival estimate for CHD associated PH was significantly better than that for idiopathic PAH (76% vs. 54%; p < 0.001). Within the CHD associated PH group, survival estimates differed particularly depending on the underlying diagnosis and treatment status. Conclusions: In COMPERA-CHD, the overall survival of patients with CHD associated PH was dependent on the underlying diagnosis and treatment status, but was significantly better as than that for idiopathic PAH. Nevertheless, overall survival of patients with PAH due to CHD was still markedly reduced compared with survival of patients with other types of CHD, despite an increasing number of patients on PAH-targeted combination therapy.

Exposure to anthracyclines (ANT) during childhood represents a high risk for development of late cardiotoxicity. Cardiotoxicity is usually detected only when clinical symptoms or progressive cardiac dysfunction have already occurred. Early detection of cardiotoxicity may lead to better therapeutic outcome. N-terminal pro-brain natriuretic peptide (NTproBNP) has been hypothesized to reflect increased left ventricular wall stress before development of echocardiographic abnormalities. The aim of this study was to detect cardiac abnormalities using plasma NTproBNP and echocardiography in asymptomatic childhood leukemia survivors treated with or without cardiotoxic anthracycline therapy.

Aims: Adults with congenital heart disease (ACHD) knowledge regarding their heart condition is crucial for optimal long-term outcome. Previous studies from Northwestern Europe showed that important gaps in ACHD knowledge still exist. This study evaluates ACHD patients’ knowledge in Central and Southeastern Europe (CESEE) and aims to identify opportunities for improving lifelong ACHD care and outcomes in this region. Methods and results: A structured survey regarding the baseline heart condition knowledge was prospectively distributed to stable ACHD patients over a 1-year period (2021–22). Patients’ responses were verified by their ACHD physicians to ensure accurate background information. Amongst 1650 patients (age 34.5 ± 14) across 14 CESEE countries, the majority (1023, 62.0%) had simple congenital heart disease with at least one previous heart procedure performed (1201, 72.8%); 1060 (64.2%) were asymptomatic, and 875 (53.8%) had secondary school education. Overall, 576 (34.9%) did not have basic knowledge regarding their congenital heart disease, and 146 (12.2%) did not have basic understanding regarding their previous heart procedure/s. Patients considered their life expectancy similar to the general population (P = 0.039). Encouragingly, 962 (59.5%) expressed a desire to learn more, and 929 (58.1%) favoured technological integration in their care. Conclusion: Significant knowledge gaps exist amongst CESEE ACHD patients regarding their heart condition. Better ACHD patient education on current health and prospects is urgently needed. The results of this study should serve for developing congenital heart disease structured transitional and educational programmes in CESEE incorporating technology for their ACHD care and education to enhance patients’ health knowledge and healthy life behaviours to positively influence their lifelong prospects.
