Percutaneous coronary intervention

Percutaneous coronary intervention is a non-surgical method used to open narrowed coronary arteries. Percutaneous coronary intervention is performed by inserting a catheter through the skin in the groin or arm into an artery and the leading tip of this catheter may contain devices such as a balloon, stent, or cutting device. The catheter and its devices are threaded through the inside of the artery back into an area of coronary artery narrowing or blockage and helps open it up. "Intervention," means that even if the person is actively having a heart attack, percutaneous coronary intervention can be used to intervene and stop the attack by opening up the narrow or blocked coronary artery. This allows blood to flow to the heart muscle. Treatment of acute heart attack is a very important use of percutaneous coronary intervention, it is also used to relieve or reduce angina, prevent heart attacks, alleviate congestive heart failure, and allows some patients to avoid surgical treatment.
