Q: What is catheterization?

A: Catheterization is a procedure used to diagnose and treat particular conditions. Cardiac catheterization, in particular involves inserting an extruded catheter into an artery or vein in the groin, neck or arm and then, via a guidewire, steering it through the blood vessels to the heart. The process is used for sensing, diagnostics and treatments of a wide variety of conditions. The process is done in a cath lab typically under fluoroscopy.
