David L.S. Morales, M.D. ’95, a pediatric cardiovascular surgeon at Texas Children’s Hospital Heart Center, performed the first implantation in the United States of an artificial heart into the chest of an 18-year-old patient. The operation took place on May 22 at Texas Children’s Hospital in Houston. The patient was born with his heart on the wrong side of his chest and his heart vessels backwards. The artificial heart will serve as a bridge to transplantation of a donated heart.
