Dr. Bass is an Associate Professor of Pediatrics and Director of the Division of Pediatric Cardiology.

Dr. Bass received his M.D. degree from the University of Mississippi Medical School. He completed his residency in Pediatrics at the University of Mississippi in Jackson and his fellowship in Pediatric Cardiology at the University of Minnesota. He joined the faculty at the University of Minnesota in 1979. He is board certified in Pediatrics and Pediatric Cardiology

Dr. Bass’s clinical interests include interventional cardiology and echocardiography.

His research interest is in interventional cardiology. He participates in the development of the Amplatzer devices. These allow repair of heart lesions (patent ductus arteriosus, secundum atrial septal defects, patent foramen ovale, muscular and perimembranous ventricular septal defects) at cardiac catheterization instead of requiring cardiac surgery.
