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.

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