Percutaneous Coronary Intervention (PCI)
Percutaneous Coronary Intervention (PCI, formerly known as angioplasty with stent) is a non-surgical procedure that uses a catheter (a thin flexible tube) to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque buildup, a condition known as atherosclerosis.
PCI improves blood flow, thus decreasing heart-related chest pain (angina), making you feel better and increasing your ability to be active. PCI is usually scheduled ahead of time.
