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.

2012 Highlights

  • John Hokanson, MD, was awarded a 3-year, $900,000 grant from the US Department of Health and Human Services Health Resources and Services Administration (DHHS-HRSA) for his project, “Wisconsin Critical Congenital Heart Disease Screening Demonstration Program.”
  • John Hokanson, MD, and Kathleen Maginot, MD, named “Top Doctors” by Madison Magazine.
  • Luke Lamers, MD, joined the Pediatric Heart Program as Director of Interventional Services. He provides state-of-the-art minimally invasive catheterization care, and is pioneering transcatheter valve replacement in children at AFCH.
