The Doctors discuss the amazing case of a man who now has two hearts, each with its own heartbeat.
A 56-year-old man was having heart failure and underwent a heart transplant, but the donor's heart was too small for the recipient. After a 7-hour surgery, the small donor heart was tucked in between the man's right lung and his original heart.
Cardiologist Dr. Joel Kahn explains this procedure has only been performed 150 times. He explains a pacemaker was also used to make the hearts beat in unison.
But will this type of heart transplant last as long as other transplants?
Dr. Kahn says one patient who had this type of procedure done has survived for 20 years.
