Hythem Nawaytou, MBChB

Pediatric cardiologist

Dr. Hythem Nawaytou is a cardiologist who cares for children with pulmonary hypertension in the hospital as well as the clinic. He performs and interprets all types of echocardiography (ultrasound of the heart), including fetal echocardiograms (used to help diagnose and evaluate many heart conditions before birth).

Nawaytou's research focuses on ways to better diagnose children with pulmonary hypertension and follow their progress over time. He also studies the use of echocardiography to evaluate heart function.

Nawaytou earned combined bachelor of medicine and bachelor of surgery degrees at Cairo University's Kasr Alainy Faculty of Medicine. He completed a residency in pediatrics at State University of New York Downstate Health Sciences University, followed by a fellowship in pediatric cardiology at UCSF and a fellowship in advanced cardiac imaging at Children's Hospital of Philadelphia.

In his free time, Nawaytou enjoys painting.
