What Exactly Is Angiography, Angioplasty, and Stent?

Angiography: A medical imaging process that visualizes blood vessels using contrast dye and X-rays.

Angioplasty: A minimally invasive technique that uses a catheter and balloon inflation to widen restricted or obstructed blood arteries.

Stent: A short mesh-like tube put in a treated blood artery during angioplasty to keep it open and prevent it from narrowing again.

PTCA , which stands for "percutaneous transluminal coronary angioplasty," is a medical procedure commonly used to treat coronary artery blockages. It involves inserting a heart stent to widen narrowed arteries, making coronary stent implantation a critical aspect of stents in heart procedures.
