Medical Treatment: Invasive Procedures
When angina symptoms worsen despite medications, you may need an invasive procedure in the cardiac catheterization lab to clear the blocked artery. These procedures are performed by a cardiologist, not a cardiac surgeon, and have fewer complications.
Coronary angioplasty (PTCA): This procedure is similar to coronary angiography (cardiac catheterization or a dye study to visualize the inside of coronary arteries) but is therapeutic as well as diagnostic.
Stent: A stent is a small, sieved, coil-like metallic tube or scaffold mounted over a balloon.
