Cardiac catheterization is an imaging procedure used to diagnose and treat some heart conditions, including arterial narrowing or blockage. The results of the catheterization will help your doctor plan the next step in your treatment.
An ICD is a battery-powered device placed under the skin (below your collarbone). It monitors your heart rate and sends electrical pulses to correct arrhythmias (dangerously rapid and chaotic heartbeats). This process is called defibrillation.
Peripheral artery disease (PAD) is a narrowing of arteries in other parts of the body—most commonly in the arteries of the legs. PAD is similar to coronary artery disease (CAD). Both PAD and CAD are caused by atherosclerosis, which narrows and blocks arteries.
Angioplasty, also called percutaneous transluminal angioplasty (PTA), is a procedure in which a thin, flexible tube called a catheter is inserted through a blood vessel and guided carefully to the place where an artery is narrowed or blocked.
