Insights
This study identified top research priorities for adult congenital heart disease (ACHD) by surveying clinicians and patients. Key areas include tetralogy of Fallot, single ventricle/Fontan patients, and systemic right ventricles, guiding future clinical research.
Area of Science:
- Cardiology
- Congenital Heart Disease Research
Background:
- Adult congenital heart disease (ACHD) clinical decision-making is limited by insufficient data.
- Identifying research priorities is crucial for advancing ACHD care.
Purpose of the Study:
- To identify and prioritize clinical research questions in adult congenital heart disease (ACHD).
Main Methods:
- A survey was developed by the Alliance for Adult Research in Congenital Cardiology (AARCC) with input from patient groups.
- The survey ranked 45 research questions by ACHD providers globally based on priority and clinical experience.
- 139 responses were analyzed to determine the top 10 research priorities.
Main Results:
- High-priority research areas include tetralogy of Fallot (pulmonary valve replacement, ICD criteria), systemic right ventricles (echocardiography, valve replacement, ICD criteria), and single ventricle/Fontan patients (vasodilators, anticoagulation, ventricular function, protein-losing enteropathy).
- Criteria for cardiac transplantation referral in ACHD patients were also identified as a priority.
Conclusions:
- The ACHD field requires prospective research to address critical clinical questions.
- This study's findings aim to guide researchers and funding bodies toward high-priority ACHD research topics.
Background:
Adult congenital heart disease (ACHD) clinicians are hampered by the paucity of data to inform clinical decision-making. The objective of this study was to identify priorities for clinical research in ACHD.
Methods:
A list of 45 research questions was developed by the Alliance for Adult Research in Congenital Cardiology (AARCC), compiled into a survey, and administered to ACHD providers. Patient input was sought via the Adult Congenital Heart Association at community meetings and online forums. The 25 top questions were sent to ACHD providers worldwide via an online survey. Each question was ranked based on perceived priority and weighted based on time spent in ACHD care. The top 10 topics identified are presented and discussed.
Results:
The final online survey yielded 139 responses. Top priority questions related to tetralogy of Fallot (timing of pulmonary valve replacement and criteria for primary prevention ICDs), patients with systemic right ventricles (determining the optimal echocardiographic techniques for measuring right ventricular function, and indications for tricuspid valve replacement and primary prevention ICDs), and single ventricle/Fontan patients (role of pulmonary vasodilators, optimal anticoagulation, medical therapy for preservation of ventricular function, treatment for protein losing enteropathy). In addition, establishing criteria to refer ACHD patients for cardiac transplantation was deemed a priority.
Conclusions:
The ACHD field is in need of prospective research to address fundamental clinical questions. It is hoped that this methodical consultation process will inform researchers and funding organizations about clinical research topics deemed to be of high priority.
