Cardiac catheterization is done using a thin, soft tube called a
catheter. A doctor inserts the catheter into a blood vessel, typically in the
groin area, using a special needle. The doctor then slowly guides the catheter
through blood vessels toward the heart. The catheter tip is moved into various
positions in the heart's chambers and vessels (coronary arteries).
