The Power of the Institute

When your child’s heart is working well – you rarely think about it. But when it’s not, you think of little else – time slows down, priorities change, you feel powerless. At the Herma Heart Institute, we do everything in our power to give you back yours. In the following video, learn how we provide the best heart care, the best outcomes and the best quality of life possible.

Why choose the Herma Heart Institute for my child’s heart care?

No matter how routine or complex your child’s heart condition may be, there are many reasons to trust the Herma Heart Institute for your child’s care:

  • High national rankings
    U.S. News & World Report ranked our heart care #5 in the nation.
  • Exceptional outcomes
    Our heart care consistently achieves outstanding outcomes – even for the most complex cases. Our pediatric heart surgery survival rates are among the country's best and have earned us a 3-star rating (the highest possible) by the Society of Thoracic Surgeons, placing us among the top 5 percent of programs in the country. We have the world's best published survival rates for hypoplastic left heart syndrome, a very complex congenital heart disease. We treat more patients than any other heart program in Wisconsin and are among the busiest centers nationally – important because research says higher volumes lead to better care and outcomes. Learn more about our outcomes.
  • All the top heart specialists your child could need
    The American Academy of Pediatrics recommends choosing care from an extensive team of pediatric heart specialists. Our comprehensive heart care team includes highly specialized congenital heart surgeons, multiple pediatric cardiologists and interventional cardiologists, fetal cardiologists, pediatric electrophysiologists, pediatric cardiac anesthesiologists and pediatric critical care specialists. These doctors lead our many specialty programs and many are ranked among The Best Doctors in America.
  • We pioneer life-saving treatments
    Not only do we offer the latest heart care techniques, but we also pioneer them and teach them to others. Care teams from across the world visit us to shadow our caregivers and observe their techniques. Learn more about Herma Heart Institute research.
  • Monitoring and follow-up boost outcomes
    Herma Heart Institute experts developed the nation’s first Home Monitoring Program, which has become a national care standard for babies who undergo certain types of heart surgery. The program is a key reason the Herma Heart Institute has one of the best published survival rates in the world for treating hypoplastic left heart syndrome. We also developed the country’s first Neurodevelopmental Follow-up Program to boost a child’s life-long success after heart surgery. And, our staff helped pioneer and prove that better outcomes for newborns undergoing heart surgery are possible with an extra degree of monitoring after surgery.
  • Second opinions welcome
    Second opinions help parents confirm that recommended treatment is right for their child. They also can surface other options to explore – even if treatment is already underway. Request a second opinion from the Herma Heart Institute online or by calling (414) 607-5280 or (877) 607-5280 (toll free).
  • Superior support for traveling families
    For families from out of the area, we’re here to help so that getting the care they need is as comfortable and convenient as possible. Herma Heart Institute experts are available 24/7 for consultations, transport and other needs.
