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