Dr. Charles T. Dotter performed the world’s first percutaneous transluminal angioplasty

On Jan. 16, 1964, Dr. Charles T. Dotter at Oregon Health and Science University (OHSU), considered the father of interventional radiology, performed the world’s first percutaneous transluminal angioplasty, a procedure in which a tapered Teflon catheter was used to open a blocked artery with the help of a live X-ray shown on a television monitor.

The procedure allowed Laura Shaw, an 82-year-old woman to keep her gangrene-ravaged left foot, which was nearly amputated due to a blocked artery. Her pain disappeared within a week and the ulcer soon healed.
