Heart Center Patient Stories

Meet Shirley

Shortly after birth, Shirley underwent open-heart surgery at Seattle Children’s to treat a rare congenital heart defect called truncus arteriosus. After returning home to Tacoma, Shirley’s family quickly established care with Josiah Penalver, MD, a pediatric cardiologist at Seattle Children’s South Sound Cardiology Clinic — just a short drive from their home.

“It’s such a relief to have Shirley’s heart team nearby,” says Shirley’s mom, Brianna. “Seattle Children's South Sound Cardiology is like having Seattle Children's Hospital in Tacoma.”

Meet Hermann

Newborn Hermann Ntuadi needed surgery for heart failure. For his family, getting the best care meant finding a team that would respect their faith. As Jehovah’s Witnesses, they abstain from accepting blood transfusions, once thought to be essential during heart operations.

Thankfully, they found Seattle Children’s, home to the nation’s largest blood conservation program. Hermann is doing great after our experts repaired his heart in a transfusion-free procedure.
