A couple spent sleepless nights when told by doctors in London that there was nothing they could possibly do to help their girl survive the rare heart conditions.

However, after collecting themselves, the couple went in for a second opinion and a complete verdict of her case. 'Daily Mail' reports the happy parents are now poised to take her home.

The couple's emotional roller coaster ride began at Kelly's 20-week scan when tests revealed the baby had hypoplastic left heart syndrome - a congenital condition affecting the left side of the heart.

Further tests showed she was actually suffering for a much rarer problem called cyanotic univentrical heart.

The cluster of abnormalities included the heart arteries and ventricles being back-to-front, an underdeveloped right side of the heart and problems with the blood vessels going to the lungs.

Doctors say the chances of a child being born with all these problems is a million to one.

Millie's low birth weight of 4lb 15oz created further complications as as she was not strong enough to withstand major corrective surgery. That is when doctors told the parents there was little they could do apart from make her comfortable and provide palliative care.

But the couple approached Birmingham Children's Hospital where the little girl underwent two operations and is now out of intensive care and recovering in the cardiac ward.

Although Millie will need more surgery in the future, doctors hope she will be home by the end of summer.
