Research priorities in single-ventricle heart conditions: a United Kingdom national study.

OBJECTIVE: To bring together stakeholders in the United Kingdom to establish national priorities for research in single-ventricle heart conditions. METHODS: This study comprised two surveys and a workshop. The initial public online survey asked respondents up to three questions they would like answered for research. Responses were classified as unanswered, already answered, or unable to be answered by scientific research. In the follow-up survey, unanswered questions were divided into categories and respondents were asked to rank categories and questions by priority. A stakeholder workshop attended by patients, parents, healthcare professionals, researchers, and charities was held to determine the final list of research priorities. RESULTS: A total of 128 respondents posed 344 research questions, of which 271 were classified as unanswered, and after removing duplicates, 204 questions remained, which were divided into 20 categories. In the second survey, 56 (49.1%) respondents successfully ranked categories and questions. A total of 39 participants attended the workshop, drawing up a list of 30 research priorities across nine priority categories. The nine priority categories are: Associated co-morbidities; Brain & neurodevelopment; Exercise; Fontan failure; Heart function; Living with a single ventricle heart condition; Management of the well-functioning Fontan circulation; Surgery & perioperative care; and Transplantation, mechanical support & novel therapies. CONCLUSIONS: Through a multi-stage process, we engaged a wide range of interested parties to establish a list of research priorities in single-ventricle heart conditions. This provides a platform for clinicians, researchers, and funders in the United Kingdom and elsewhere to address the most important questions and improve outcomes in these rare but high-impact CHDs.

Leg pains in CHD: a distressing symptom of a wider problem.

PurposeAnecdotal reports suggest that children and young adults with CHD frequently experience pain in their legs. The purpose of this pilot study, performed by Little Hearts Matter patient organisation, was to assess the burden of leg pains in this group and begin to investigate associated factors and consequences for daily living. METHODS: An internet-based survey was distributed by Little Hearts Matter patient organisation. After anonymisation and collation, responses were analysed and compared with their healthy siblings. RESULTS: Of the 220 patients who responded, 94% reported leg pains compared with 30% of siblings (n=107; p<0.001). In respondents, pain was typically reported to occur in the lower legs or around the knees or ankles, often associated with crying and screaming (49.0%) and most commonly occurring at night-time (82.0%). Individuals taking aspirin and those who were more active were more likely to report leg pains. Older age was associated with leg pain that occurred with stress (p=0.02) and at night (p=0.05). Analgesia (64.1%) or massage (53.9%) was the preferred option for alleviation. There was no gender bias, association with diagnosis, surgical history, and/ or relationship with diagnosed orthopaedic issues. CONCLUSION: Leg pains are more frequent in those with CHD compared with their healthy siblings. Aetiology is uncertain, but pains share many common characteristics with benign "growing pains".
