Cardiology FAQ's

Do I need a cardiac catheterization, angiogram or intervention?

Cardiac catheterization refers to the introduction of some form of catheter into a blood vessel with the purpose of measuring pressures and/or introducing contrast material to study the anatomy of a blood vessel or the heart.  An angiogram refers more specifically to the injection of contrast material, which allows us to define a specific area.   Intervention is a term used for the process of mechanically treating an obstruction within an artery, usually to the heart.  Interventions include balloon angioplasty, which is the expansion of a decrease in the opening of the artery by plaque material.  In many cases now the balloon angioplasty is followed by the insertion of a stent, which is a mesh device, used to maintain the integrity of the opening of the artery.
