Total artificial heart
In June 1996, a 46-year-old Chinese American Mr. Yao ST received the world's first total artificial heart implantation done by Dr. Jeng Wei at Cheng-Hsin General Hospital in Taiwan. This pneumatic Phoenix-7 Total Artificial Heart was manufactured by a dentist Kelvin K Cheng and his colleagues at the Taiwan TAH Research Center in Tainan, Taiwan. With this experimental artificial heart, the patient's BP was maintained at 90-100/40-55 mmHg and cardiac output at 4.2-5.8 L/min. After 15 days of bridging, Mr. Yao received combined heart and kidney transplantation. As of September 2011, he is still very well and is currently living in San Francisco.
