Story highlights A 31-year-old Nashville woman survived a heart transplant years ago, only to die following childbirth

Her husband's friend started a GoFundMe page that has raised more than $350,000

(CNN) After giving birth to her baby girl, Megan Moss Johnson got to hold her daughter in her arms, feed her and burp her.

It was a celebration of new life for Johnson, who received a heart transplant seven years ago, and her husband, Christian music artist Nathan Johnson.

But the 31-year-old mother experienced complications and died just eight hours later of unspecified causes.
