AI Article Synopsis
- Carcinoid heart disease (CHD) is a serious condition caused by high levels of serotonin from certain tumors, mainly affecting the right side of the heart and making it harder for patients to survive.
- This study looked at 84 patients with CHD over three time periods from 1984 to 2018 and found that survival rates have improved a lot in recent years.
- The research showed that valve replacement surgery helps patients live longer and that a blood test called NT-proBNP can help doctors understand how sick a person is with CHD.
Article Abstract
Carcinoid heart disease (CHD) is a serious cardiac condition which is caused by elevated serotonin in the systemic circulation, secreted by neuroendocrine tumours (NET). It mostly affects the right-sided heart valves, where it causes fibrotic disturbances and is associated with worse survival. In this study, we describe a large cohort of patients with CHD and provide an insight into their survival over the past decades. All consecutive patients with a serotonin producing NET and CHD referred to the Netherlands Cancer Institute that presented with CHD or developed CHD during their follow up time were included from 1984 until 2021. Patients were divided into three time periods: 1984-2000, 2000-2010 and 2010-2018. Median N-terminal pro B-type natriuretic protein (NT-proBNP) and serum serotonin levels were stratified according to tricuspid regurgitation severity. Kaplan-Meier curves and log rank test were used for visualisation of survival. Cox regression was used for identification of the characteristics associated with disease specific mortality (DSM). A total of 84 patients with CHD were included of whom 49 (58.3%) were male. Median age at NET diagnosis was 62.3 (range 23.9-81.7) years, and median time to development of CHD was 1.1 (range 0-24.2) years. NT-proBNP was significantly higher when more severe tricuspid regurgitation (TR) was present (p = .027). Median survival from CHD diagnosis for 1984-2000, 2000-2010 and 2010-2018 were 1.3 (confidence interval [CI]: 0.9-1.6), 1.9 (CI: 1.2-2.6) and 3.9 (CI: 1.7-6.2) years (p = .025). Valve replacement surgery (VSR) occurred more frequent in later time periods. VSR (hazard ratio [HR] 0.33, p = .005) and NT-proBNP (HR 1.003, 1.00-1.005, p = .036) were significantly associated with DSM. The prognosis of patients with CHD has improved over the past decades, possibly caused by more VSR. NT-proBNP is a valuable biomarker in patients with CHD. Clinical practice should be aimed at timely diagnosis and intervention of CHD.

Background: The population of adult CHD patients is continuously increasing. The underlying CHD affects performance and prognosis, but also has a significant impact on quality of life, psychosocial behaviour, anxiety and emotional disturbances. This study analyzes these parameters of patients after one or more heart operations and the possible psychological effects of medical and psychosocial complications at the Department of Cardiology of the Kepler University Hospital Linz.

Infants requiring surgery for congenital heart disease (CHD) are at an increased risk of neurodevelopmental delay. Developmental Care Rounds (DCR) have been implemented widely to support the neurodevelopment of children with CHD while admitted to the hospital. This study aims to describe caregiver perceptions of DCR at a quaternary academic children's heart center.

The use of conduction system pacing (CSP) in adults with congenital heart disease (CHD) is growing, however data remain limited. In patients with congenitally corrected transposition of the great arteries following the double switch operation, existing CSP tools and techniques require modification to allow for the anterior displacement of the atrioventricular node and proximal conduction system in addition to navigating the tortuous route of the atrial redirection. We report the successful use of CSP focusing on the technique of delivery tool modification to allow stability on the basal septum for deployment to the area of the distal His bundle and proximal left bundle branch.

Background: Aging is associated with acquired comorbidities that potentially influence the natural history and outcomes of adults with congenital heart disease (CHD). The purpose of this study was to compare the clinical characteristics, as well as the incidence and correlates of all-cause mortality between different age groups.
Method: Adults with CHD were categorized into 3 age groups based on age at baseline encounter: Group 1 (age 18-40 years); Group 2 (age 41-65 years), and Group 3 (age >65 years).
