What is Balloon Angioplasty?
Balloon Angioplasty (Percutaneous Transluminal Coronary Angioplasty or PTCA) is type of PCI in which a small balloon at the tip of the catheter is placed near the blocked or narrowed area of the coronary artery. When the balloon is inflated, the blockage is compressed against the artery walls and the diameter of the blood vessel is widened (dilated) to increase blood flow to the heart.
