The Single Ventricle Research Fund (SVRF) — is an annual research award program that supports foundational studies aimed at improving outcomes for individuals with single ventricle heart disease. By addressing the organ- and multi-organ-level complications and clinical sequelae that drive long-term morbidity and mortality, the SVRF seeks to close critical gaps in understanding and treatment, and accelerate progress toward better, more predictive, and preventative care.

Applicants may apply for either the Independent Investigator or Career Development tracks. The Independent Investigator Track is open to both tenure and non-tenure track independent investigators, including instructors, assistant professors, and tenured faculty. The Career Development Track is open to postdoctoral fellows or postdoc equivalents who hold mentored positions. Independent Investigator Track applicants can apply for up to $600,000 in direct costs, and Career Development Track applicants may apply for up to $300,000 in direct costs, over 3 years.

In its sixth cycle, the SVRF welcomes foundational research that is directly relevant to improving outcomes for individuals with single ventricle heart disease.

Proposed projects must be led by principal investigator(s) who hold doctoral degrees (e.g. PhD, MD, PsyD, or equivalent doctorates). Proposals are accepted for two program tracks: Independent Investigator and Career Development.

Independent Investigator Track: Eligible investigators include independent investigators of all levels (including those with Instructor or Assistant Professor status). Collaborative proposals (e.g., includes multiple lead investigators who make significant contributions) are encouraged. One principal investigator must be selected as the primary contact, with all other lead investigators listed as co-investigators. Up to five (5) co-investigators may be added to each project, and they must meet the same eligibility requirements as the principal investigator.

Career Development Track: Eligible investigators include postdoctoral fellows or equivalents holding a mentored position. Collaborative proposals will not be accepted through this track.
