Percutaneous Coronary Intervention
Percutaneous Coronary Intervention (PCI) is a procedure used to unblock coronary arteries. It is very similar to a coronary angiogram in that a tube is placed in the top of the leg and a catheter inserted via that tube up to the coronary arteries. In PCI, a small wire is passed down the artery and a small balloon is then used to unblock the artery. Once a balloon has made a passage, a coronary stent (a small metal cage) is put into the artery (all through the same catheter) to scaffold it open.
