A medical procedure used to open blocked or narrowed blood vessels, often involving the use of a balloon to widen the vessel.
The doctor recommended angioplasty to improve blood flow to the heart.
Angioplasty is formed from "angio-" (from Greek "angeion", meaning vessel) and "-plasty" (from Greek "plastos", meaning molded or formed). The term refers to the surgical procedure of reshaping or repairing blood vessels.
Think of 'vessel' ('angio-') being 'molded' or 'formed' ('-plasty') to remember that angioplasty is a procedure that reshapes blood vessels.
