Doctors at Children's Hospital in Boston have made history by implanting a permanent pacemaker into a baby that weighed just 2.2 pounds.
The Rhode Island baby boy was the smallest ever to receive the tiny pacemaker, which is about the size of a quarter. The doctors say that because Angel Cassandra's mother has lupus, his heart had slowed to about one-third what it should. So, he was delivered by C-Section a month early, a month ago.
Monday, the hospital released this video and said the baby is doing great, and the procedure appears to have been a huge success.
"He's doing great. He had, a premature infant and needed to be on a ventilator for about a week and once he got over that, he's done really quite nicely," says Dr. Mark Alexander who is Angel's cardiologist.
Dr. Alexander says thanks to the pacemaker, little Angel should be able to lead a normal life.
