Who We Are

Executive Board


SOPE President


Mark Lewin, MD, is a Professor and Chief of the Division of Pediatric Cardiology, University of Washington School of Medicine/Seattle Children’s Hospital and Director of our Prenatal Diagnosis and Treatment program.


Dr. Lewin previously served as the Director of our Pediatric Echo Lab (2001-2009). He ran an echo telemedicine program with ~1400 echos/year now transmitted from across the Pacific Northwest.


His professional activities include Board member of the Pediatric Council of the American Society of Echocardiography (2005-2007), pediatric representative to the Advocacy Council, American Society of Echocardiography (2007-2010), and chair of the Pediatric Track of the American Society of Echocardiography, 21st Annual Scientific Sessions (2011).

SOPE Vice President


Tim Slesnick, MD, is an Associate Professor of Pediatrics at Emory University School of Medicine. His clinical focus is non-invasive imaging, both echocardiography and cardiac magnetic resonance imaging (CMR), and he serves as the Director of Pediatric Cardiac Magnetic Resonance Imaging for Emory University.

From a research standpoint, he has an interest in both structural heart disease as well as myocardial assessment. Much of his focus is on advances in echocardiography, such as blood speckle tracking, and in CMR technology, such as non-contrast angiograms, four-dimensional flow velocity imaging, and highly accelerated image acquisition techniques.

Finally, through collaborations with Georgia Tech, his team is working on advanced computational modeling of patient-specific CMR images to allow both surgical planning and long-term prognostication in complex congenital heart defects such as double outlet right ventricle and single ventricle anatomies.
