Cześć! Mikolaj (Mickey) traveled from Poland to Boston Children’s Hospital after he was diagnosed with congenitally corrected transposition of the great arteries (CC-TGA) and a small ventricular septal defect (VSD). Using advanced pressure-volume (PV) loop analytics, his Heart Center team was able to measure his heart’s workload and determine the right timing for biventricular repair. Now almost six years old, Mickey is thriving — active in school, sports, and loving his life as a big brother! Learn more about his story in the link below http://ms.spr.ly/6180QjHP2
