When it comes to uncovering the cause or extent of heart and vascular problems, all of the latest tools and techniques are available to our heart and vascular physicians.
As physicians examine each patient’s condition to pinpoint its cause and plan for treating the problem, they have access to many tests and procedures for diagnosing heart disease and vascular disease.
3-D echocardiogram — uses ultrasound waves to investigate the action of the heart, presented in a three-dimensional (3-D) image. We have the longest clinical experience in the state using this technique. Learn more about echocardiograms.
64-Slice LightSpeed Volume Computed Tomography (VCT) Scan — a powerful medical CT scanner that is unique in its ability to produce clear, three-dimensional images of blood vessels to detect coronary artery disease (CAD); VCT combines rapid X-ray scanning with multiple CT to produce highly detailed images of the heart and vessels. We were the first in the world to use the 64-Slice LightSpeed VCT Scan technology. Learn more about the 64-Slice LightSpeed VCT Scan.
Angiography — a procedure performed to view blood vessels after injecting them with a dye that outlines them on X-ray.

Coronary artery calcium scan/scoring — a non-invasive test that uses CT imaging to measure the amount of calcium in the arteries. Also called a heart scan, it helps determine the risk of coronary artery disease (CAD) or heart attack.
CT angiography (CTA)/cardiac CTA — produces images of the blood vessels and tissues in a particular body structure by combining computerized tomography (CT) scanning with an injection of a special dye. A CT scan is a type of X-ray that uses a computer to make cross-sectional images of the body. Cardiac CTA produces images of the heart’s structure and function, including valves and chambers. We are leading the way in next-generation CT angiography with the 64-Slice LightSpeed Volume Computed Tomography (VCT) scanner, offering the most advanced, detailed images available.

Dobutamine stress echo test — an echocardiography test that involves taking a medication called dobutamine while being closely monitored; the medication stimulates the heart as if a person is exercising; the test is used to evaluate a person’s heart and valve function when he or she is unable to exercise on a treadmill or stationary cycle. Learn more about echocardiograms.
Drug stress test — a test that involves taking a medication while being closely monitored; the medication stimulates the heart as if a person is exercising; the test is used to evaluate a person’s heart and valve function when he or she is unable to exercise on a treadmill or stationary cycle
Duplex ultrasound — a procedure that combines Doppler flow and conventional imaging information to allow physicians to see the structure of blood vessels; duplex ultrasound shows how blood is flowing through the vessels and measures the speed of the flow of blood; it can also estimate the diameter of a blood vessel and the amount of obstruction (if any) in a blood vessel
Echocardiogram (“echo”) — a test that uses sound waves to create a moving picture of the heart; the picture is much more detailed than an X-ray image and involves no radiation exposure. Our state-of-the-art Echocardiography Laboratory performs thousands of echo procedures a year, including transthoracic echocardiogram (TTE), transesophageal echocardiogram (TEE), intracardiac echocardiogram (ICE), and cardiac resynchronization therapy (CRT) evaluation. Learn more about echocardiograms.
Electrocardiogram (EKG, ECG) — a non-invasive procedure for recording electrical changes in the heart. We perform about 30,000 electrocardiography procedures each year. Other types of EKGs include holter monitors, event recorders and loop recorders. Learn more about electrocardiograms.
Electrophysiology (EP) study — an invasive procedure that tests the heart's electrical system. EP studies may be performed to help evaluate the effectiveness of medications, to “map” or locate the point of origin of a dysrhythmia, or to gather other important details about the patient’s condition. Learn more about EP studies.
Exercise stress test — a screening tool to test the effect of exercise on the heart; also called heart stress test or treadmill stress test.
Extremity arterial mapping — uses non-invasive duplex ultrasound technology to examine blood flow in the arteries in the arms and legs. Learn more about extremity arterial mapping and other tests provided in our vascular laboratory.
Event recorder (or loop recorder) — a device that records irregular heart rhythm episodes over extended periods of time. Learn more about event recorders.
HeartFlow® Analysis — a noninvasive test to detect the presence of coronary artery disease. The first of its kind test provides a personalized, color-coded 3D model of the coronary arteries, allowing physicians to determine how narrowed arteries impact blood flow without an invasive procedure. The Froedtert & MCW health network is a national leader in utilizing HeartFlow Analysis, having performed more than 500 tests.
