Adrian Kantrowitz performs the first human heart transplant in the United States.

A human heart transplant is a surgical procedure performed to replace a failing or diseased heart with a healthy heart from a donor. It is typically reserved for patients with end-stage heart failure or severe cardiac conditions that are unresponsive to other treatments, such as medications or less invasive surgeries. The procedure involves removing the recipient’s damaged heart, connecting major blood vessels to the donor heart, and carefully suturing it into place to restore normal blood flow. Post-surgery, patients require lifelong immunosuppressive therapy to prevent rejection of the donor heart by their immune system. Although complex, heart transplants significantly improve survival rates and quality of life for recipients. Success hinges on factors like donor-recipient matching, surgical expertise, and post-operative care. Despite advancements, challenges remain, including a limited supply of donor hearts and risks of complications such as infection, rejection, or organ failure.
