Diagnosing and Treating Heart Conditions

Your Care is Our Priority

At St. Luke's Cardiology Associates,
our specialists excel at providing
customized, patient-centered care, using
the most advanced tests and treatments.

Our highly-skilled specialists have a special affiliation with St. Luke's Heart and Vascular, giving our patients full access to the latest treatments and technologies.

Tilt Table Test

Used to evaluate unexplained fainting and severe lightheadedness. Patients begin by laying on a table, which is then tilted up to simulate the movement from lying down to standing. Blood pressure and heart rate monitoring during the test measure how your body responds to the change in position.


Holter Monitor

Used to discover any irregular heart rhythms. Electrodes are stuck to your chest and hooked to a small battery-operated device. The Holter monitor is usually worn 24 to 48 hours and then returned to your doctor's office. Patients keep track of their activity and any symptoms.


MUGA Scan

A multiple gated acquisition (MUGA) scan is used to judge how well your heart is pumping. A safe, radioactive material called a "tracer" is injected into your bloodstream. Special cameras trace the substance as it moves through the heart.


Nuclear Stress Testing

Used to detect problems while you're heart is exercising. A safe, radioactive material called a "tracer" is injected into your bloodstream. The tracer is detected by a special camera. Pictures of your heart are taken during a stress test to see how your heart behaves. During a stress test, you walk on a treadmill or ride an exercise bike. Another set of pictures is taken later, while your heart is at rest.


Cardiac Catheterization

Used to help diagnosis and treat heart conditions. A long, thin flexible tube (a catheter) is inserted in a blood vessel in your arm, neck or groin and threaded to your heart. The catheter allows doctors to perform diagnostic tests such as coronary angiography.


Coronary Angiography

Used to detect problems with blood flow to and in the heart. A special dye is injected into your bloodstream through a catheter. Once the dye travels to the heart, it will make the coronary arteries and any problems visible on an X-ray.


Echocardiogram

Used to allow doctors to see the heart beating. A trained sonographer manipulates a transducer, which emits high-frequency sound waves near your heart. The sound waves are translated into three-dimensional, moving pictures of the heart.


TEE

A two-dimensional echocardiogram used to evaluate the valves and chambers of the heart. During a transesophageal echocardiogram (TEE), the back of your throat is numbed and a scope inserted down to the esophagus so doctors can see the heart beating and valves.


Cardiac CT

A cardiac computed tomography (Cardiac CT) is used to detect problems with the heart. An X-ray machine takes clear, detailed pictures of your heart. Sometimes an iodine-based dye is injected to highlight veins and arteries during the X-ray.


Cardiac MRI

Used to look at the structure and function of the heart. Unlike a Cardiac CT which uses X-ray and emits radiation, a cardiac MRI uses radio waves, magnets and a computer to generate pictures or your heart as it's beating, producing still and moving pictures of your heart and blood vessels.


Balloon Angioplasty

Used to clear a blockage in the artery. A thin tube is threaded through a blood vessel to a plaque-blocked area of the artery. A tiny balloon on the end of the tube is inflated at the blockage, pushing the plaque against the artery walls. This widens the artery and restores blood flow. Sometimes a stent (small, metal mesh tube) is left in the artery to keep it open.


Carotid Endarterectomy

Used to unblock a carotid (neck) artery. You have two carotid arteries that carry blood to your brain. The surgeon will open the artery to remove the blockage, typically plaque. A catheter is used to reroute blood during the surgery.
