Cardiac catheterization is a procedure in which a thin, flexible tube (catheter) is guided through a blood vessel to the heart to diagnose or treat certain heart conditions, such as clogged arteries or irregular heartbeats. Cardiac catheterization gives doctors important information about the heart muscle, heart valves and blood vessels in the heart.

Specialist use this procedure to diagnose many potential heart issues. Cardiac catheterization only requires a thin incision to perform and causes less discomfort and overall will heal more quickly.
