Q

Percutaneous Transluminal Coronary Angioplasty

A

Procedure where they pass a catheter with a small inflatable balloon attach to its tip into the obstructed coronary artery -> when reach obstruction the balloon is inflated which flattens the atherosclerotic plaque against the vessel wall -> vessel is stretched to increase size of the lumen which improves blood flow
