Explanation: "The procedures called Percutaneous Coronary Interventions (PCI) are among those that are the most effective for opening blocked blood vessels that cause heart attacks. Doctors may perform PCI, or give medicine to open the blockage, and in some cases, may do both."
Why is this important?: "The heart is a muscle that gets oxygen through blood vessels. Sometimes blood clots can block these blood vessels, and the heart can't get enough oxygen. This can cause a heart attack. Percutaneous Coronary Interventions (PCI) are procedures that are among the most effective ways to open blocked blood vessels and help prevent further heart muscle damage. A PCI is performed by a doctor to open the blockage and increase blood flow in blocked blood vessels. Improving blood flow to your heart as quickly as possible lessens the damage to your heart muscle. It also can increase your chances of surviving a heart attack. There are three procedures commonly described by the term PCI. These procedures all involve a catheter (a flexible tube) that is inserted, often through your leg, and guided through the blood vessels to the blockage. The three procedures are:
- Angioplasty - a balloon is inflated to open the blood vessel.
- Stenting - a small wire tube called a stent is placed in the blood vessel to hold it open.
- Atherectomy - a blade or laser cuts through and removes the blockage."
