Nicholas P. Pietris

Nicholas P. Pietris, MD, serves as Associate Professor in the Department of Pediatrics at the University of Maryland School of Medicine, specializing in pediatric cardiology with clinical expertise in non-invasive cardiac imaging and cardiopulmonary exercise stress testing.

His educational pathway includes:

• 2001: B.S. in Biochemistry from State University of New York at Stony Brook
• 2005: M.D. from State University of New York at Buffalo, School of Medicine and Biomedical Sciences
• 2005-2006: Pediatrics Internship at Yale New Haven Hospital
• 2006-2008: Pediatrics Residency at Yale New Haven Hospital
• 2008-2011: Pediatric Cardiology Fellowship at Yale New Haven Hospital
• 2011-2013: Advanced Cardiovascular Imaging Fellowship at Medical University of South Carolina

Dr. Pietris' research centers on congenital heart disease and acquired pediatric cardiovascular disorders, emphasizing non-invasive imaging modalities (echocardiography, MRI, CTA), exercise physiology testing, and innovative stem cell applications. His scholarly work explores tissue engineering solutions for vascular grafts and diagnostic approaches for complex cardiac anomalies, aiming to advance therapeutic interventions for pediatric patients.

Analysis of his 2014-2016 publications reveals consistent focus on translational cardiovascular research, particularly stem cell therapies for neonatal cardiac repair, mechanical circulatory support systems, and advanced imaging techniques for congenital defects. Key methodological trends include porcine modeling, speckle-tracking echocardiography, and CT/MRI applications in pediatric populations.

Board certified in pediatrics and pediatric cardiology, Dr. Pietris maintains active membership in the American Heart Association, American College of Cardiology, and American Society of Echocardiography, reflecting his commitment to professional development and clinical excellence in pediatric cardiology.
