Cardiac Catheterization

Heart specialists, known as cardiologists, use cardiac catheterization to diagnose and treat a variety of heart conditions. To help you understand this procedure, let’s first look at how a normal heart works. Your heart is responsible for delivering blood to all parts of the body. Veins carry oxygen-poor blood from your body to your heart. Arteries carry oxygen-rich blood away from your heart to nourish your body. The heart is actually two pumps side-by-side that work together to distribute blood throughout your body. The right side pumps blood on a short trip to the lungs to receive oxygen while the left side delivers the oxygenated blood throughout the body. Each side of your heart has two compartments, or “chambers.” The top chambers are the atria. The bottom ones are the ventricles. Special valves keep blood flowing from one chamber to the other without moving backwards, like one-way gates.
