Challenges and opportunities in assessing right ventricular structure and function: a Roadmap for standardization, clinical implementation and research.

Given its crucial role in determining patient symptoms and outcomes in various cardiopulmonary diseases, the thorough and accurate assessment of right ventricular function is essential for both diagnosis and ongoing patient monitoring. In the era of precision medicine, a more detailed characterization of patients with cardiopulmonary diseases is needed, especially with the emergence of novel pharmacological and device-based therapies, such as transcatheter tricuspid valve intervention, gene therapy in patients with cardiomyopathy and anti-obesity interventions for patients with heart failure. Precise and reproducible quantification of right ventricular morphology and function are crucial for risk stratification, the selection of different therapies for the appropriate patients and the evaluation of treatment outcomes. As our understanding of right ventricular pathophysiology expands, the need for sensitive markers of functional deterioration, reliable prognostic indicators and more precise surrogates for clinical trials becomes increasingly important. In this Roadmap, we address current challenges in the standardization of image acquisition, analysis and interpretation across different modalities. We explore the factors limiting the clinical adoption of more advanced approaches and provide expert recommendations to overcome these barriers. Additionally, we outline potential next steps for incorporating parameters of right ventricular function as surrogate end points in multicentre clinical trials of new drugs or devices, and highlight new research opportunities, including the integration of artificial intelligence technologies. Finally, we issue a call for international collaboration on selected priority areas.
