Cardiac catheterization is also known as cardiac angiogram or left heart catheterization. This procedure is commonly performed in the hospital to assess for blockage in heart artery (CAD). It is also used to study the function of heart and valves.
A catheter is very small tube and inserted through the vein in groin or wrist with local anesthesia, using a narrow fiber passed upwards inside the artery in the heart.
Blockages can be seen by injecting dye into the heart arteries. If there is narrowing, the narrowing can be widened and a stent will be placed.
