Emma and Taylor Bailey, the San Tan Valley conjoined twins whose medical challenges drew international attention, died on Tuesday from heart-surgery complications in Seattle. They were 3.
The surgery was one of several procedures the girls underwent to strengthen the heart prior to separation surgery, which was to take place later this year.
Connected at the chest and lower abdomen, Emma and Taylor shared a common heart and liver. Doctors determined that the twins would die if not separated because too much strain was being put on their seven-chambered heart.
The twins are survived by their parents, Tor and Mandy, and siblings Paige, Drew, Cole and Blake.
