Why is angioplasty needed?

Angioplasty is needed to treat narrowed or blocked arteries, often due to atherosclerosis, which can lead to reduced blood flow to the heart or other vital organs. This procedure involves inserting a small balloon into the affected artery and inflating it to widen the vessel, restoring blood flow and alleviating symptoms such as chest pain or shortness of breath. Angioplasty can also prevent serious complications like heart attacks by improving circulation. It is often performed as a minimally invasive alternative to bypass surgery.
