Division Highlights - Cardiology

The Division of Pediatric Cardiology and the 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.
