A woman who died from an undiagnosed heart condition four days after giving birth could have been saved if her condition had been spotted and treated earlier, a hospital has said.
Selwa Romedan, 21, was found to have a narrowing of a valve in her heart after she collapsed and died in September 2016 following the birth of her daughter Sadenselwa.
In the days before her death, she suffered chest pains and shortness of breath and was told by staff at St James's Hospital, in Leeds, that she was anaemic and tired and was given a blood transfusion and told to rest.
Leeds Teaching Hospitals NHS Trust has now apologised to Miss Romedan's family and said an investigation found the young mother may have survived if her mitral valve stenosis condition had been diagnosed and treated.
Dr Yvette Oade, acting chief executive at the Trust, said:
Miss Romedan's partner, Muhanad Adem, described his pain at knowing the mother of his child could have survived.
He said: "It makes it worse knowing that they could have done something to save her. We came here to be safe and I put my trust in them."
The couple, who fled from Eritrea, north Africa, settled in Leeds after being granted asylum in the UK.
Mr Adem, 29, said his daughter's birth was the happiest day of their lives.
He said: "I cried with happiness when Saden was born and she was put in my arms."
But less than a day after being sent home, Miss Romedan was taken back to St James's Hospital by ambulance suffering shortness of breath and was diagnosed with anaemia and given a blood transfusion.
She was discharged the following day but her symptoms returned and the hospital's maternity assessment unit advised that she was probably just tired and told her to rest.
She collapsed in the early hours of September 25, 2016, after getting up to feed her daughter and telling Mr Adem she could not breathe.
Mr Adem said: "She said 'I am dying, I am going from you'. And she just collapsed - she fell down and I fell down with her."
The forklift truck driver was later told Miss Romedan had died.
Mr Adem now devotes his life to looking after his daughter.
