A cardiac catheterization is a procedure that allows a cardiologist to look more closely at the arteries of the heart and how blood is flowing.
A thin tube called a catheter is guided through a blood vessel, often from the wrist or groin, toward the heart. Contrast dye may be used to help visualize the coronary arteries.
Cardiac catheterization may be recommended after abnormal testing, concerning symptoms, suspected blocked arteries, or certain hospital presentations.
It can help answer an important question: Is there a significant blockage affecting blood flow to the heart?
