A two-year-old girl who was born with a serious heart defect has had a life-saving operation thanks to a 3D printer.
Mina had a hole between two chambers of her heart, but doctors were able to use the printer to create a model to help surgeons plan the successful operation.
Mina and mum Natasha spoke to BBC Breakfast, along with Dr Tarique Hussain who printed the model of her heart.
