Dr. Hijazi is an interventional cardiologist who specializes in treating congenital & structural heart disease in both children and adults.  He is a pioneer in the non-surgical repair of congenital and structural heart defects.

After graduation from medical school and upon completion of his internship in Amman, Jordan, Dr. Hijazi came to the United States to begin postgraduate training in the Department of Epidemiology and Public Health at Yale University, where he was subsequently awarded a Masters of Public Health.  He remained at Yale University where he completed a residency in Pediatrics and a fellowship in Pediatric Cardiology.  Upon completion of his fellowship training, he joined the faculty at Tufts University School of Medicine as an Assistant Professor.  In 1997 he was promoted to Associate Professor of Pediatrics and Medicine, and in 1999 Dr. Hijazi accepted faculty appointment at the University of Chicago as Endowed Professor of Pediatrics and Medicine and Chief of the division of cardiology. He has been successful in building a preeminent Pediatric Cardiology Program, which is nationally and internationally recognized for its outstanding clinical service and innovative technologies.  In 2007 Dr. Hijazi became the Director of the Rush Center for Congenital and Structural Heart Disease at Rush University Medical Center and in 2010, he became the James A. Hunter, MD, University Chair.

His major area of interest is in the development of techniques and catheters/devices to help treat or cure congenital and structural cardiac disease without open-heart surgery.  Dr. Hijazi is very prolific with more than 300 peer reviewed published articles, seven books and over 40 book chapters.  In 1994 he published an article describing the technique of multiple coil closure of patent ductus arteriosus (PDA).  His new technique enabled cardiologists to close moderate to large size PDAs using multiple coils.  In 1997 he published the first results of the initial clinical use of the new Amplatzer septal occluder device for atrial septal defects (ASD)

Subsequently he has been a primary investigator in testing the Amplatzer family of intracardiac devices in the United States.  Dr. Hijazi wrote the protocols for these trials and presented the results of these studies to the Food and Drug Administration.  The trials have involved catheter closure of atrial septal defects, patent ductus arteriosus, patent foramen ovale (PFO) and ventricular septal defects.  These studies resulted in the FDA approving the first ASD closure device for use in children in 2001.  This study was published in the Journal of the American College of Cardiology in 2002.

His work has not been limited to the non-surgical repair of cardiac defects.  Dr. Hijazi was the first to describe how intracardiac echocardiography (ICE) can be used to assist in guiding transcatheter closure of ASD/PFO.

His annual Pediatric & Adult Interventional Cardiac Symposium (PICS/AICS) is a four-day conference which brings together a select international faculty who provide demonstrations, live operations and the latest research breakthroughs in interventional cardiology for congenital & structural heart disease.  This symposium attracts more than 750 interventional cardiologists from more than 60 countries around the world.  Based upon this model, he is currently establishing collaborative pediatric cardiology research and clinical programs in China.


Currently, Dr. Hijazi is involved in evaluating percutaneous valve implantation (without surgery) for patients with defected pulmonary valves, senile aortic valve stenosis and leaky mitral valves. He performed the first operation (Pulmonary valve implantation) of its kind in the USA December 13th, 2005 on a 16-year old boy successfully.

In May 2013, he performed the first two pulmonary valve implantations using the new Venus P valve in China.

Further, he is currently involved with two companies to develop a percutaneous aortic valve for elderly patients with degenerative aortic valve stenosis.


On May 11th, 2008, Dr. Hijazi became the 31st president of the Society for Cardiovascular Angiography and Interventions (SCAI), the major organization for interventional cardiologists and has more than 4000 members worldwide.

In 2011, Mayor Thomas Menino declared July 24th, 2011 as the Ziyad M. Hijazi day in Boston, MA.

In January, Dr. Hijazi has become the 1st Chair of Pediatrics at Sidra Medical & Research Center, Doha-Qatar and Director, Sidra Cardiovascular Center of Excellence. In May 2014, Dr. Hijazi became the Acting Chief Medical Officer of Sidra Medical & Research Center, a role he completed in December 2015.

Also, in May 2014 he became a Master of the Society for Cardiovascular Angiography & Intervention (MSCAI), among the first class of recipients.
