Sarfaraz Khan couldn't believe it when the doctors said that his little girl's heart was so large, it was killing her. But it was ultimately Mumbaikars' big hearts that ended up saving her, after they came to the desperate father's aid and donated R20 lakh for the 10-year-old's heart transplant. Sania, a Std V student, was diagnosed with Dilated Cardiomyopathy (enlarged heart) in 2016.
