Division Highlights - Cardiology

The Division of Pediatric Cardiology and the Pediatric Heart Program of the American Family Children’s Hospital provides outstanding comprehensive care to children with congenital or acquired heart disease throughout Wisconsin and the region.

Clinical specialties include pediatric and adult congenital heart disease diagnosis and management, including care of fetuses and newborns with complex structural heart problems; noninvasive cardiac imaging; interventional catheterization; inherited arrhythmias and interventional electrophysiology; exercise physiology; and preventive cardiology.

National Institutes of Health-funded research investigates the biology of inherited cardiomyopathies and the response of the immature heart to physiologic stress, and the use of newborn screening to identify congenital heart defects.

2013 Highlights

  • J. Carter Ralphe, MD, received a $50,000 award from the Children’s Cardiomyopathy Foundation for his project, “Human IPS Cells and ECT in the Study of Hypertrophic Cardiomyopathy.”
  • With the recruitment of Luke Lamers, MD, in summer 2012, the division expanded its cardiac catheterization capabilities, providing approximately 150 services that previously were referred elsewhere.
  • The American Family Children's Hospital pediatric preventive cardiology clinic, led by Amy Peterson, MD, Ann Dodge, NP, and Erin Marriott, NP, saw 193 patients in 2013, a nearly 250% increase from the 78 seen in 2012. The clinic was launched in 2011 to help children reduce or eliminate risk factors for adult cardiovascular disease.
