Percutaneous transluminal coronary angioplasty (PTCA, or balloon angioplasty) is performed in the cardiac cath lab. This procedure helps restore a healthy blood flow to the heart by reopening arteries narrowed by fatty plaque. The procedure happens in 3 steps:
- An expandable balloon catheter is guided into a narrowed section of a coronary artery.
- The balloon is then inflated, and compresses plaque against the artery wall.
- The balloon catheter is deflated and then withdrawn, re-establishing blood flow through the newly widened artery.
