A heart that was dropped on the ground while being transported to a hospital has been successfully transplanted into a 28-year-old hair stylist.
Dr Jaime Saldivar said Erika Hernandez does not yet know that her new heart made national news in Mexico when a medic stumbled and the plastic-wrapped heart tumbled out of a cooler onto the street two weeks ago.
Dr Saldivar said it will be up to the family to tell her.
A rosy-cheeked Ms Hernandez spoke briefly with reporters and thanked the donor's family, saying: "I have no words to express what I'm feeling right now."
Ms Hernandez was born with a congenital heart defect.
She received the heart of a man who died in a car accident.
