Cardiologist Explains Clinton Heart Procedure

Cardiologist Dr. Stephen Corday goes in depth explaining the heart procedure that former President Bill Clinton underwent on Thursday.

Two stents were inserted into one of Clinton's coronary arteries on Thursday at New York Presbyterian Hospital, and Dr. Corday explains that a stent is like a small "metal scaffolding." He tells ET, "When the artery is ballooned open, the stent is then inserted and inflated and it continues to hold the artery open so the artery won't collapse." He adds that medicine is released through the stent to help hold the artery open.

Of the procedure in general, Dr. Corday says, "Obviously this is a situation where things had to be done perfectly, but it's done in a routine manner throughout the United States, as a matter of fact, throughout the world."
