Hannah weighed lower than 5 kilos when she was born a month prematurely. Regardless of rising after her two cardiology interventions, her arteries had been smaller than most infants who’ve the process.

Nonetheless, her cardiac surgeon, Dr. Peter Chiu, was in a position to reconfigure her MAPCAs right into a purposeful pulmonary artery system in a unifocalization operation that lasted 16 hours. “That was a really lengthy night time,” Brian recollects. “It was aggravating, but it surely went properly.”

Hannah had another surgical procedure on her arteries not lengthy after. “Hannah’s journey was fairly an extended street, however that second surgical procedure made an enormous distinction,” Brian says. “She is in a stronger place.”
