Coronary Balloon Angioplasty (PTCA): Opening Blocked Heart Arteries

Coronary balloon angioplasty, also known as percutaneous transluminal coronary angioplasty (PTCA), is a minimally invasive procedure used to open blocked coronary arteries. These blockages can restrict blood flow to the heart, potentially leading to a heart attack or death.

How it Works:

  1. A small balloon-tipped catheter is inserted into the blocked artery.
  2. The balloon is inflated, compressing the plaque (fatty buildup) against the artery wall.
  3. The balloon is deflated and removed, leaving the artery wider and improving blood flow.
  4. Often, a stent (a small mesh tube) is then deployed at the site of the blockage.
  5. The stent acts as a scaffold, keeping the artery open and preventing it from collapsing.
