Apa itu Angio and stenting.?

Angioplasty: Emergency coronary angiography and coronary balloon angioplasty (percutaneous transluminal coronary angioplasty, or PTCA) are available in hospitals equipped with a full-service cardiac catheterization laboratory. This is the most direct method of removing blockage in a coronary artery.

• Coronary balloon angioplasty is an extension of coronary angiography.
  
  
• A long, thin tube (catheter) is inserted in an artery in the groin or arm.
  
  
• At the tip of the catheter is a tiny, elongated balloon, which is threaded over a hair-thin guidewire into the narrowed coronary artery.
  
  
• Once the balloon is positioned at the blockage in the coronary artery, it is inflated.
  
  
• The balloon pushes aside the plaque and clot that are blocking the artery, allowing blood to flow more freely.
  
  
• The balloon is then deflated and removed with the catheter.

Stenting:

A stent is a small, metal springlike device that may be inserted into a coronary artery after balloon angioplasty.

After the catheter and balloon are removed, the stent stays in place, holding the artery open.

A stent is better than angioplasty alone at keeping the artery from narrowing again.
