WATCH: Simon Keith underwent a successful second heart transplant on Sunday followed by a four-hour surgery for a kidney transplant on Monday.
Keith is famous for being the first pro athlete with a heart transplant. The now 53-year-old received his initial heart transplant at the age of 21.
Keith’s health deteriorated late last year as his heart and kidney both began to fail. He’d been waiting for a transplant since. The transplant took place in a hospital in San Diego.
