Angioplasty is a medical procedure frequently used to address narrowed or blocked arteries. This technique involves inserting a small balloon catheter into the affected artery, which is then inflated to widen the artery and restore blood flow. Sometimes, a stent—a small mesh tube—is placed to keep the artery open.

As a minimally invasive alternative to open surgery, angioplasty can treat various conditions, such as coronary artery disease, peripheral artery disease, and renal artery stenosis. The procedure is generally regarded as safe and effective, with a low risk of complications.
