Percutaneous Coronary Intervention
Percutaneous Coronary Intervention (PCI)/ Coronary Angioplasty/ PTCA Angioplasty is a procedure used to open blocked coronary arteries so that
adequate blood supply is restored. A special catheter (a long, flexible
tube) with a small balloon at the tip is placed into an artery in your
groin or arm. The catheter is then moved to the clogged artery in your
heart. The balloon is inflated and deflated several times to push the
plaque against the artery wall and open the artery.
Stents: A stent is a small metal coil, slotted tube, or mesh structure that is
placed permanently inside a coronary artery to help keep it open following
an angioplasty. The stent helps hold the artery open, improves the flow
of blood, and relieves symptoms of coronary artery disease.
Atherectomy: Once a blockage in your coronary artery has been diagnosed from a heart
catheterization, an atherectomy is a non-surgical procedure that is used
in conjunction with an angioplasty in certain patients. Atherectomy is
a procedure that uses a catheter and special cutting or grinding tools
to remove plaque from artery walls. The plaque is removed and can later
be examined and studied.
