Balloon angioplasty
Coronary angioplasty is accomplished using a balloon-tipped catheter inserted through an artery in the groin or arm to enlarge a narrowing in a coronary artery.
Coronary artery disease occurs when cholesterol plaque builds up (atherosclerosis) in the walls of the arteries to the heart.
Angioplasty is successful in opening coronary arteries in 90% of patients.
40% of patients with successful coronary angioplasty will develop recurrent narrowing at the site of balloon inflation
