For a person suffering from coronary artery disease, the arteries in the heart may completely or partially be blocked by a sticky material called plaque, and this blocks the blood flow.
Percutaneous Coronary Intervention (PCI) is a non-surgical procedure to unblock the coronary arteries that are narrowed by plaque buildup, and restore the blood flow to the heart muscles.Typically, a catheter placed on a guide wire is inserted inside the blocked artery to help widen it.
Percutaneous Coronary Intervention (PCI) is also called Percutaneous Transluminal Coronary Angioplasty (PTCA), and commonly known as Angioplasty.
Based on the type of instrument used, the procedure can be categorized into
- Balloon Angioplasty
- Laser Angioplasty
Angioplasty is generally combined with stent placement to support the walls of the artery and prevent it closing again.
