Figure 2. Patient‐centered research in valvular heart disease (VHD).

This figure shows the multifaceted aspects of what we define and characterize as patient‐centered research in VHD. The patient (red) is a participant in and focus of the research. The outer ring represents some of the many research questions and knowledge gaps in the field. The most common research tools and methodologies to address those knowledge gaps are shown in the next inner circle (green). Those doing and funding the research are shown in the final inner circle (blue).
