Mission & Focus Areas
The Foundation’s stated mission is to “support cardiothoracic surgeons in research and education.” Its programs include support for clinical and translational research by young cardiothoracic surgeons, including research on quality and outcomes and on innovative therapies, procedures, and technologies. Other named programs include the Graham Traveling Fellowship, Medical Student Diversity Scholarship, Resident Research Cardiac Scholarship, Summer Intern Program, and several named fellowship and scholarship programs.
Its 2024 grants went to universities, hospitals, and other institutions. For example, West Virginia University describes its mission as fostering and supporting research at WVU; Johns Hopkins University describes its mission as educating students, fostering independent research, and bringing the benefits of discovery to the world. Children’s Wisconsin describes its work as providing integrated pediatric health care, while City of Hope describes its mission as making hope a reality for people touched by cancer and diabetes. These are the grantees’ stated missions, not the Foundation’s.
Grantmaking
In 2024, the Foundation reported 23 grants totaling $807,709. Grant amounts ranged from $8,500 to $80,000, with a median of $40,000. The filing says research grants are generally $40,000–$80,000 per grantee, with amounts dependent on available unrestricted funding or restricted-donation agreements. It describes this support as helping young investigators begin research efforts and pursue larger funding opportunities.
Among the largest reported 2024 grants were $80,000 to Stanford University for research scholarships; $65,000 to the American Association for Thoracic Surgery for Edwards 2020; and $50,000 each to Boston Children’s Hospital and Children’s Hospital of Wisconsin for the Surgical Investigator Program. Other $50,000 grants included awards to City of Hope for the AATS Foundation Equity Award, Johns Hopkins University for the Surgical Investigator Program and the WTS Mid-Career Investigator Award, and West Virginia University for the Surgical Investigator Program. The Foundation also gave $10,000 to Temple University in 2024.
The filing says award recipients must report upon completion of their research or fellowships, and that the Foundation verifies direct grants to supported organizations are used for approved scholarships.
