Tests & Treatments

The following tests and treatments are some of the most common tests and treatments offered by specialists in this area. These specialists offer many other advanced tests and treatments for a wide range of medical problems. Please call (888) 352-RUSH (7874) if you have questions about specific tests or treatments not listed here.

  • Angiogram

    Angiogram is an X-ray exam of the blood vessels to diagnose blockages, narrowing or other blood vessel problems. Also referred to as angiography, this procedure uses a special dye (or contrast agent) to make the blood vessels visible.
  • Angioplasty is a minimally invasive procedure used to open a coronary (heart) artery that is completely or mostly clogged with deposits of fat and cholesterol called plaque.
  • Atherectomy

    Atherectomy is used to remove plaque buildup from the inside of an artery. During this minimally invasive procedure, doctors insert a small burr-like device or a laser into the artery via a catheter. They use the device or laser to shave, cut off or dissolve the plaque. Often, a stent (a wire mesh or fabric tube) is then placed in the artery to keep it from re-narrowing.
  • Cardiac Catheterization

    Cardiac catheterization is a minimally invasive procedure in which a catheter is inserted into a blood vessel in the arm, groin or neck and threaded to the heart. It is used to diagnose and treat a variety of heart conditions, including coronary artery disease, heart attack, chest pain, defects, valve problems, infections and tumors, as well as measure blood flow and oxygen levels in different parts of the heart.
  • Cardiac Resynchronization Therapy

    Cardiac resynchronization therapy is used to treat people with advanced heart failure whose right and left ventricles are not contracting at the same time. A small device called a biventricular pacemaker is implanted in the chest, under the skin. The pacemaker sends electrical impulses to the heart muscle to match up the beating of both sides of the heart. This resynchronization improves the heart’s function.  
  • Electroencephalogram (EEG)

    Electroencephalogram (EEG) is a test that measures the electrical activity of the brain. It is often referred to as a brain-wave test. An EEG is useful in diagnosing and treating many neurological disorders. An EEG is performed by attaching electrodes to the scalp and recording the brain’s activity.
  • Holter Monitor

    Holter monitor uses an external recording device and electrodes to monitor the heart’s electrical activity for periods of 1 to 3 days. It is used to diagnose arrhythmias and silent myocardial ischemia and to determine whether treatments for these conditions are effective.  
  • Implantable Cardioverter Defibrillators (ICD)

    Implantable cardioverter defibrillators (ICD) are small electronic devices placed in people who are at risk of sudden cardiac death due to ventricular tachycardia, ventricular fibrillation, a weakened or enlarged heart, congenital heart disease or a genetic health condition. Implanted in the chest, the ICD detects any life-threatening rapid heartbeat, or arrhythmia, and sends an electrical shock to the heart to bring the rhythm back to normal.
  • Electrophysiologists at Rush University Medical Center offer the latest in pacemaker technology, including leadless pacemakers (e.g., Micra) and His bundle pacing, to treat arrhythmias.
  • Positron Emission Tomography (PET)

    Positron emission tomography (PET) is a method doctors use to diagnose a variety of diseases, including several types of cancer. PET uses a small amount of a radioactive substance and a computer to create images of the inside of a patient’s body.
  • Stent Placement

    Stent placement is often done as part of an angioplasty procedure to widen and restore blood flow through blood vessels that have become narrowed, as well as to reduce the risk of brain and abdominal aortic aneurysms rupturing. A stent (a metal mesh or fabric tube) is used to prevent re-narrowing or reinforce a weak area in a blood vessel. After coil embolization to seal off a wide-necked aneurysm, a stent may be needed to create a barrier that keeps the coil in place.  
  • Valvuloplasty

    Valvuloplasty, or balloon valvuloplasty, is a catheter-based procedure used to treat heart valves that don’t open properly. During the procedure, a balloon threaded through a catheter is inflated to widen the opening of the valve, improving the valve’s function and blood flow. It is most effective in treating narrowed pulmonary valves and is also a good option for mitral valve stenosis.  
  • Cardiologists and cardiac surgeons in Rush's Advanced Heart Failure and Mechanical Circulatory Support Program offer ventricular assist devices for either temporary heart support or as long-term therapy for people who can't have heart transplants.
