Sixteen Research Teams Selected for 2025 Single Ventricle Research Fund Award

July 22, 2025

The sixteen research teams awarded through the 2025 Single Ventricle Research Fund (SVRF) — which includes thirteen independent investigators and three post-doctoral investigators — embody the expanding ambition and momentum within the single ventricle research field. This year’s cohort spans a dynamic range of emerging and underexplored research areas — from lymphatic biology and hepatic dysfunction to systems-level modeling and computationally guided surgical interventions — marking a powerful step forward in foundational discovery focused on single ventricle heart disease.

Nearly 90% of the primary investigators are new to single ventricle research, a clear signal that fresh perspectives are continuing to shape and advance foundational science in the field. The diversity of career stages and research areas within this cohort reflects the power of pairing long-term field development with support for the next generation of investigators poised to drive it forward.

A majority of the awarded projects in this cohort focus on outcomes-driven foundational science — uncovering the drivers of disease to ultimately improve and develop targeted therapies. The evolution of focus areas represented across SVRF award cycles, from the program’s inception to present day, highlights the field’s collective progress toward clinically meaningful impact.

About the Single Ventricle Research Fund

SVRF continues to shape the future of care for individuals with single ventricle heart disease, advancing hypothesis-driven research that explores the mechanisms behind the most pressing complications of single ventricle circulation. These multi-year grants support foundational science that is essential to laying the groundwork for targeted therapies and accelerating patient impact.
With each successive cycle, SVRF pushes the boundaries of what’s possible in single ventricle research. This year, more investigators applied, more disciplines engaged, and more proposals targeted underexplored but high-potential areas of inquiry. Alongside SVRF’s support for established independent investigators, we also introduced a Career Development track, designed for projects conducted by mentored researchers.
