Personal History:

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 pediatric cardiac surgery.

After completing his 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).

Research Interests:

Non-invasive cardiac imaging (speckle tracking and three dimensional echocardiography), low radiation dose CTA (computed tomographic angiography), Stem cell therapy for use in congenital heart disease and cardiomyopathy

Clinical Specialty:

General pediatric cardiology, cardiac non-invasive imaging (fetal, transthoracic and transesophageal echocardiography), cardiac MRI, CT angiography, and cardiopulmonary exercise stress testing
