Your doctor can place the tip of the catheter into various parts of the heart to measure the pressures within the heart chambers or take blood samples to measure oxygen levels.

Your doctor can guide the catheter into the coronary arteries and inject contrast dye to check blood flow through them. (The coronary arteries are the vessels that carry blood to the heart muscle.) This is called coronary angiography.

These are some of the other procedures that may be done during or after a cardiac cath:
