balloon angioplasty. [bÉloÌoÌnâ²]. a method of dilating or opening an obstructed blood vessel by threading a small, balloon-tipped catheter into the vessel. The balloon is inflated to compress arteriosclerotic lesions against the walls of the vessel, leaving a larger lumen, through which blood can pass.
Also known as Percutaneous Coronary Interventions [PCI], Balloon Angioplasty and Coronary Artery Balloon Dilation. Special tubing with an attached deflated balloon is threaded up to the coronary arteries. The balloon is inflated to widen blocked areas where blood flow to the heart muscle has been reduced or cutoff.
