Mother who had a heart transplant dies after giving birth

The unthinkable happened just hours after she gave birth to a beautiful baby girl.

Megan Moss Johnson, 31, passed away eight hours after she delivered Eilee Kate on June 27, 2018, as reported by Liftable.

Doctors were unsure what caused her death, but Megan once suffered from a heart problem. When she was younger, Megan had a heart transplant.

As a teenager, she had suffered from myocarditis, which inflames the middle section of the heart's wall.

She battled with this heart condition for seven years. She almost died during the Easter weekend of 2010. She was afflicted with pneumonia and could barely eat and breathe.

But her condition improved and she underwent a heart transplant.

She married Nathan Johnson two years after her heart transplant. Nathan is a guitarist for award-winning contemporary Christian musician, Josh Wilson.

Megan became pregnant in 2016 and gave birth to their first child on 2:40 a.m. on June 27. She had a normal and uneventful delivery.

The new mother was still able to hold and feed her baby, as reported by People.

Eight hours later, Megan started to suffer from complications. By 11 a.m., she was pronounced dead.

"Nothing was wrong before that," People quoted Josh Wilson, Nathan's friend, and bandmate, as saying.

"It was to the point [after the delivery] where their parents and grandparents said, 'We're going to go sleep, we'll see you in the morning.'"

Wilson said doctors had told Megan that her heart condition wouldn't be an issue during her pregnancy.

She had yearly checkups and doctors told her she was all good to get pregnant. Doctors closely monitored her throughout her pregnancy and didn't find any signs she could suffer from fatal complications.

Wilson said Nathan and Megan were deeply in love with each other. He said Nathan would always brag about his wife, making her his subjects in many of his social media posts.

Wilson had created a GoFundMe page for Nathan and Eilee. The page has raised over $400,000 as of April 9, 2018.
