HeartFlow® FFRct Analysis is a non-invasive diagnostic tool that begins with a standard coronary CT angiogram (CTA). Advanced artificial intelligence and computational fluid dynamics (CFD) are then used to create a 3D digital model of the patient’s coronary arteries. This detailed model allows physicians to analyze how blood flows through the vessels, pinpointing areas of narrowing or reduced blood flow to provide a more accurate understanding of a patient’s heart health without invasive procedures.
How the Analysis is Performed
HeartFlow Analysis begins with a CTA, a non-invasive imaging test that takes detailed pictures of the heart and its blood vessels. Then, these images are securely reviewed by advanced artificial intelligence, and powerful computer modeling is used to create a highly detailed, digital 3D model of the patient’s coronary arteries.
HeartFlow can also simulate how blood flows through a patient’s arteries, allowing physicians to see if any areas are narrowed or restricted. Instead of simply showing the structure of the arteries, HeartFlow provides real-time information to reveal whether a blockage is truly affecting blood flow to the heart. These visuals provide the care team with detailed information about the patient’s condition to help them determine whether medications, lifestyle changes or procedures are needed to treat the patient.
The entire process is non-invasive; patients do not need to do anything beyond the typical CT scan. Benefits include:
- A non-invasive and pain-free analysis of the heart
- No needles, catheters or wires required
- Improved diagnostic accuracy for both the patient and care team
- Personalized and detailed reports for each patient
- Quick patient results for faster decision-making and treatments
Who May Benefit
HeartFlow Analysis is designed for individuals who are showing early signs of coronary artery disease (CAD) – a leading cause of heart attacks – or those who need more clarity in their diagnosis. It is beneficial for patients experiencing symptoms like chest pain, tightness, or pressure, which are common indicators of reduced blood flow to the heart.
Patients with risk factors such as high blood pressure, high cholesterol, diabetes, a history of smoking, or a family history of heart disease may also benefit from an analysis. In some cases, a patient may have undergone a stress test or other cardiac diagnostic test that was inconclusive or abnormal. HeartFlow can provide a quick, non-invasive way to get more precise answers before proceeding with potentially unnecessary invasive procedures.
Candidates include:
- Those who have symptoms that suggest a possible blockage in the coronary arteries,
- Those at higher risk of heart disease due to lifestyle or medical history; and
- Those who are being evaluated for coronary artery disease but want to avoid unnecessary procedures.
Ultimately, a cardiologist will determine if HeartFlow Analysis is appropriate based on a patient’s unique symptoms, risk factors and previous test results.
