Dr. Pietris is a pediatric cardiologist who specializes is non-invasive cardiac imaging and cardiopulmonary exercise stress testing. After completing his undergraduate and medical studies (Bachelor of Science in Biochemistry, SUNY Stony Brook and Medical Doctorate, SUNY Buffalo) he completed a residency in pediatrics and fellowship in pediatric cardiology at Yale New Haven Hospital. There, his research involved non-invasive imaging using ultrasound and CTA (computed tomographic angiography) of small animal tissue-engineered vascular grafts which were being studied in order to develop similar grafts for use in congenital cardiac surgery. After completing his primary fellowship at Yale, he continued his training and research in advanced pediatric cardiac imaging within the Children's Heart Program at the Medical University of South Carolina (MUSC). Dr. Pietris’ clinical focus includes general pediatric cardiology, cardiopulmonary exercise stress testing and cardiac non-invasive imaging (fetal, transthoracic and transesophageal echocardiography, cardiac CTA/MRI). Dr. Pietris’ academic interests include non-invasive cardiac imaging (echocardiography, MRI, CTA), cardiopulmonary exercise testing, in addition to exploring the potential applications of stem cell therapy in congenital heart disease. Dr. Pietris is board certified in pediatrics and pediatric cardiology. He is a member of the American Heart Association, American College of Cardiology and the American Society of Echocardiography.
Clinical and research focus are in the area of congenital heart disease and acquired pediatric cardiovascular disease
