A one-year-old baby is recovering from a heart transplant at the Royal Brompton Hospital.
The family of Carina Marcangelo say she is in a critical condition following surgery on Sunday but making steady progress.
Carina had a disease which damages the heart and became the youngest person in Britain to be fitted with a mini-defibrillator.
Carina has cardiomyopathy which damages the heart. She spent her first birthday completely sedated on life support at the Royal Brompton as she awaited a donor organ.
She became the youngest child to be fitted with a mini defibrillator (ICD) in her chest in November at just 9 months old. The device gave her heart a shock if its rhythm worsened.
Carina could only receive a heart from a one-year-old to a small five-year-old. The average waiting time for a heart is around 3 months.
