A series of invasive examinations of the heart, typically including detail pressure measurements within the heart chambers, x-ray photographs (angiograms) of the pumping chambers and the coronary arteries, and the calculation of certain values based on these studies. The cardiac catheterization report is a summary of many different normal and abnormal states affecting the patient. The procedure requires the patient remain motionless under the fluoroscopy table until the measurements and pictures are completed. This study is the gold standard for diagnosis of most cardiac conditions.
x-ray examination of the blood vessels of the heart after administration of a contrast medium.

A procedure in which a catheter is inserted into a blood vessel and guided into the heart to measure the blood flow and evaluate any structural defects.
Cardiac catheterization (also called cardiac cath or coronary angiogram) is a procedure that allows the doctor to "see" how well your heart is functioning. The test involves inserting a long, narrow tube called a catheter into a blood vessel in your arm or leg, and guiding it to your heart with the aid of a special X-ray machine. Contrast dye is injected through the catheter so that X-ray movies of your valves, coronary arteries and heart chambers can be created. See the Diagnostic Tests page for more information.

Once inside, pictures may be taken of the arteries of the heart, pressures of the heart chambers measured, or the electrical activity of the heart evaluated.
Insertion of a catheter through the blood vessels into the chambers of the heart to measure pressure or to inject a dye to visualize the coronary arteries.
A procedure that involves inserting a fine, hollow tube (catheter) into an artery, usually in the groin area, and passing the tube into the heart. Often used in conjunction with angiography and other procedures, cardiac catheterization has become a prime tool for visualizing the heart and blood vessels and diagnosing and treating heart disease.

Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart. This is done for both investigational and interventional purposes. Coronary catheterization is a subset of this technique, involving the catheterization of the coronary arteries.
