Open Now! Single Ventricle Research Fund
August 26, 2026
The seventh cycle of the Single Ventricle Research Fund (SVRF), Additional Ventures’ flagship research award program, is now open.
Our flagship funding program — 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.
The 2027 SVRF welcomes research aligned with the focus areas and strategic topics described in Additional Ventures’ 2026 Research Roadmap. We are particularly interested in proposals that seek to elucidate the mechanisms underlying, prevent, or reverse the interrelated organ- and multi-organ-level sequelae that contribute to long-term morbidity and mortality.
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. Indirect costs up to 10% will be provided in addition to the total funded amount.
Letters of intent for SVRF 2027 are due November 10, 2026.
