Audrina Cardenas, who was born with her small heart beating outside the body, was not expected to live for many days

Audrina’s mother Ms Cardenas told the Houston Chronicle that she was aware of the condition of her baby at a scan taken at 16 weeks. She added that it was very difficult to make the choice to let the infant undergo surgery.
Despite the miraculous recovery, Audrina is not out of the woods yet and needs to undergo some more procedures.
Dr Carolyn Altman, a pediatric cardiologist at the Texas hospital, stated in a press release that her prognosis is uncertain, “Despite Audrina's misplaced heart, she was born with no other syndromes or genetic conditions that would cause additional stress or complications on her heart,” he added.
