You might remember the story from earlier this year about baby Teegan Lexcen. Born with just one lung and half a heart, and a defect so rare that doctors hadn’t come across it before, Teegan was sent home with hospice and not expected to live beyond a month or so. After a few months Teegan was still fighting and her parents sought a second opinion. Through some online research they found Dr. Redmond Burke, the chief of cardiovascular surgery at Nicklaus Children's Hospital in Miami, who agreed to help. Burke turned to Dr. Juan Carlos Muniz, a pediatric cardiologist who specializes in imaging, to make a 3-D model of Teegan's heart.
