If you have chest pain, shortness of breath or other symptoms of coronary artery disease (CAD), your doctor may recommend a computerized tomography (CT) scan and other types of tests to determine whether there’s narrowing or blockage of the coronary arteries leading to your heart.

HeartFlow, a new advanced diagnostic tool, allows your doctor to even better assess your arteries.

What is HeartFlow?

CAD is the leading cause of death for both men and women in the United States. It develops when the arteries leading to the heart narrow or become blocked, which may lead to a reduction in blood flow to the heart, causing chest pain, heart attacks and death. Despite being the most common form of heart disease, many of the non-invasive tests available today — such as stress testing — have low accuracy rates in detecting the disease.

Main Line Health is advancing the diagnosis of CAD with the HeartFlow Analysis. This non-invasive heart test provides a personalized 3D model of your coronary arteries that shows how each blockage impacts blood flow to your heart. This detailed information, which was previously only available through an invasive procedure, helps your doctor determine the next step in your treatment plan.

Main Line Health was the first health system in the region to offer this state-of-the-art diagnostic testing option.

What to expect from cardiac catheterization

Your doctor will order a coronary CT scan to look for blockages. If additional information is needed, your doctor may order a HeartFlow Analysis, which doesn’t require another appointment and there’s no additional risk to you.

Using your CT scan, HeartFlow technology creates a personalized digital 3D model of your coronary arteries. With trained specialists and powerful computer algorithms, the HeartFlow Analysis calculates how much each blockage limits your blood flow.

Your doctor receives a digital, color-coded 3D model of your coronary arteries, which helps you and your doctor determine the next step in your treatment plan.

Benefits of HeartFlow technology

HeartFlow technology provides a more detailed view of the significance of your coronary artery blockage than a standard coronary CT scan and helps your doctor better determine the appropriate treatment of care.

It’s non-invasive, poses no additional risk to you and reduces the need for follow-up testing and evaluation.
