Balloon Angioplasty is a procedure performed to widen heart arteries when they are clogged with a buildup of cholesterol, cells or other substances (plaque). Angioplasties restores normal blood flow to patient’s heart muscle. Once the occlusion is outlined by angiography, angioplasties performed to open narrowed arteries by using a long, thin tube called a catheter to help the artery widen and decrease its chance to be clogged again. After that, the balloon is inflated at the occlusion in the artery and inflated several times to achieve enough widening at the occlusion. This causes the plaque to compress to artery wall and opens the narrowed spot. Balloon angioplasty was used as the only nonsurgical invasive treatment modality in the past until recently. With the invention of stents and other intravascular treatment modalities this technique is used as adjunctive technique to be combined with other techniques.
