Cardiac Catheterization

Test Overview

Cardiac catheterization is a test to check your heart. This test uses a thin, flexible tube called a catheter that is inserted into the heart through blood vessels.

A cardiac catheterization can check blood flow in the coronary arteries. It also checks the function of different parts of the heart, such as the heart chambers, the heart valves, and the wall of the heart. In children, this test is used to check for heart problems that have been present since birth (congenital heart defect).

This test can include a coronary angiogram, which checks blood flow in the coronary arteries. An angiogram can show if you have narrowed or blocked arteries from coronary artery disease.
