To her family, Tatiana Legkiy looked completely healthy when she was born. But a pediatrician who listened to her heart heard something off. So within a few days of being born, she saw a specialist who did an echocardiogram and who, alarmed by the results, called an ambulance to take her to the hospital in Modesto, Calif.
From there, she was rushed to a hospital in San Francisco. The newborn’s heart was failing.
