Angioplasty is the mechanical widening of a narrowed or totally obstructed blood vessel. These obstructions are often caused by atherosclerosis. The term angioplasty is a portmanteau of the words angio (from the Latin/Greek word meaning "vessel") and plasticos (Greek: "fit for moulding"). Angioplasty has come to include all manner of vascular interventions typically performed in a minimally invasive or percutaneous method. This book presents recent advances in this fast-moving field.
