In 1995, British doctors designed a radical solution to save an 8-month-old girl with major heart problems. They implanted a donor heart directly onto her own failing heart. After 10 years with two blood-pumping organs, the powerful drugs Clark was taking to prevent her from rejecting the donor heart caused cancer, which led to chemotherapy. Even when doctors lowered the doses of drugs to suppress Clark's immune system, the cancer spread, and Clark's body eventually rejected the donor heart. Luckily, by that time, Clark's own heart seemed to have fully recovered. In February 2006, Dr. Victor Tsang of Great Ormond Street Hospital in London, and other doctors removed Clark's donor heart and she made a full recovery. "Thanks to this operation, I've now got a normal life just like all of my friends," said Clark. Her parents marveled at her recovery, saying at one point they were told she would be dead within 12 hours. Today Hannah Clark is a healthy 24-year-old living a normal life and working in the child care industry.
