Picture of Balloon Angioplasty
Balloon angioplasty is a technique used to open blocked coronary arteries via a balloon-tipped catheter. The catheter is inserted into an artery in either the groin or the arm and is then advanced to the heart. Once the catheter is in place, the balloon is expanded to press cholesterol plaque build up against the artery wall, opening the vessel. The technique is successful in approximately 90% of patients. Plaque may build up in the same location in some patients.
