Percutaneous transluminal angioplasty involves passage of a balloon-tipped catheter to the site of arterial narrowing and inflation of the balloon to reduce the obstruction. This technique is always done in conjunction with angiography of the vessel to be treated. Successful percutaneous transluminal angioplasty results in a reduction of the arterial stenosis and a decrease in the trans-stenotic pressure gradient (1, 2). The mechanisms of action are not known completely but are thought to involve compression of atherosclerotic plaque, disruption and splitting of the plaque and the intima and media of the artery, and stretching of the arterial wall (2-7).
