PHOENIX — The Transplant Center at Mayo Clinic in Arizona achieved the highest transplant volume in history in 2025 by performing 917 solid organ transplants in one year, according to data from the Organ Procurement and Transplantation Network (OPTN). Over the past five consecutive years, Mayo Clinic in Arizona has performed more adult solid organ transplants (heart, lung, kidney, pancreas and liver) than any other transplant center in the U.S. Mayo also previously received national recognition for performing the world's first total larynx transplant on a patient with active cancer.

As a result of this level of experience in Arizona, patients across the state and the Southwest have access to the best in transplant medicine close to home. Transplants are among the most complex procedures in modern medicine. Centers that perform them frequently are known to have lower complication rates and better outcomes because these highly skilled teams are developing the national best practices and know how to manage complications across the patient care journey.

"This milestone reflects the power of an integrated approach to transplant care and what's possible when extraordinary teams come together with a singular focus: getting the gift of life to people who need it most," says Bashar Aqel, M.D., transplant hepatologist and director of the Transplant Center at Mayo Clinic in Arizona. "Our teams in Arizona are supported by the depth of expertise across Mayo Clinic, allowing us to care for patients with extraordinary complexity while advancing transplant medicine as a whole."

Combined, Mayo Clinic Transplant Center, encompassing Arizona, Florida and Minnesota, is the undisputed leader in transplant medicine, delivering more lifesaving transplants than any other healthcare provider. Mayo Clinic's transplant volumes in 2025 show the demand for adult solid organ transplantation continues to grow as innovative techniques are expanding the pool of donors and hope for patients who are waiting.

"We are deeply grateful to the donors and donor families whose generosity makes this work possible and for the patients who trust us with their care," says Dr. Aqel.
