It's the tail end of April 2023, and a bubbly pair of twin girls is running around a Chuck E. Cheese in Yonkers, N.Y. A group of family and friends forms around 3-year-olds Chloe and Contessa Gee on a flashing LED dance floor, ready to sing 'Happy Birthday.' Inside each girl is an indominable spirit and a heart full of joy. And inside the Gee twins' hearts is our Amplatzer Piccolo Occluder. It filled the tiny holes the girls had in their hearts when they were born at 23 weeks and weighed one pound each. Chloe and Contessa are the stars of the party, of course. But this wondrous device, smaller than a pea in size, plays a crucial supporting role. In addition to helping the girls, it fills their mother, Saleena, with peace of mind — to know that the Amplatzer Piccolo Occluder would help the daughters she calls her 'miracle babies' be their amazing selves. And, on this special occasion, party it up. 'Just seeing them get to the age of 3 is really exciting,' Saleena Gee said. 'I bought them candy bags. Everybody was happy. After the party they came home, they took their little showers and they went straight to bed. They were so tired.' A typical toddler birthday — for two toddlers who are anything but typical.
