When your child has a heart problem, finding the right specialist isn't just important—it's everything. Here's what actually matters when choosing the best children's heart centre. Children's hearts aren't just smaller versions of adult hearts. They're developing, they respond differently to treatment, and they need doctors who understand these differences intimately. The best centres don't just treat heart conditions—they specialize exclusively in pediatric cardiac care. That means pediatric cardiologists, cardiac surgeons trained in delicate child procedures, and nurses who know how to calm a scared five-year-old before an echocardiogram.
