Dr Sahn graduated summa cum laude from Brooklyn College C.U.N.Y with a major in Chemistry and graduated cum laude from Yale University School of Medicine in 1969. As a fellow in Pediatric Cardiology at the University of California San Diego School of Medicine, Dr. Sahn started studying neonatal diagnosis and physiology with M-mode echo and performed the first real-time 2D echocardiogram ever done in the USA in 1972 -- the beginning of a career of more than 30 years of pioneering efforts in development and applications of Cardiac Ultrasound. After working in Tucson, Arizona, from 1973 to 1982 with Stanley Goldberg and Hugh Allen, Dr. Sahn returned to San Diego to become the Director of UCSD Pediatric Cardiology, and began clinical studies of MRI in congenital heart disease at UCSD in the late 1980s. He relocated to Oregon Health Sciences University in Portland Oregon in 1992 as Director of the Clinical Care Center for Congenital Heart Disease. During the year 2000, he undertook a sabbatical as a Visiting Research Scholar at the Lucas MRI Center at Stanford University to study MRI physics and instrumentation with Norbert Pelc, Ph.D.
Dr. Sahn is an expert in cardiac imaging and cardiac diagnosis. Pediatric and adult congenital heart disease patients are sent from all over the world for his opinions and for his care. He is integrally involved with ultrasound and cardiac magnetic resonance as well as with prenatal diagnosis and management of congenital heart disease. He currently has more than $9.5 million dollars of active research support from the National Institutes of Health in areas of Ultrasound technology development, and telemedicine applications of ultrasound.
