Definition
Left heart catheterization is the passage of a catheter (a thin flexible tube) into the left side of the heart. The procedure may be performed to obtain diagnostic information about the left side of the heart or to treat certain types of heart conditions.
The procedure can also be used to determine pressure and blood flow in the heart's chambers, to collect blood samples from the heart, and to examine the arteries of the heart by a type of X-ray called fluoroscopy.

Why is the Test Performed?
The procedure is performed to evaluate cardiac valvular disease, heart function and blood supply, congenital heart anomalies, and to determine the need for cardiac surgery. Therapeutic catheterization may be used to repair certain types of heart defects, open a stenotic heart valve, and dilate obstructed arteries or grafts in the heart.
