The 39-year-old mother of two has recently undergone a life-saving operation so radical that she now, in effect, carries her heart around in a rucksack.

The operation is so unusual that there is no one else in Britain in the same situation. Inside Selwa’s 15lb backpack are batteries, an electric motor and a pump that pushes air through tubes to power plastic chambers in her chest which push blood around her body.
