World’s tiniest baby to survive heart surgery (470 grams)

He weighed merely 470 grams at birth and was just the size of a palm. He was born prematurely after 28 weeks (5.5 months). His eyes hadn’t opened, lungs weren’t developed, skin resembled parchment paper, too fragile and delicate to touch, and he had heart complications.
After 15 days of birth, he underwent a heart surgery and has now become the tiniest miracle baby to have undergone a PDA (patent ductus arteriosus) corrective operation.
