Direct visualization of the epicardial coronary arteries is currently the reference standard to confirm the presence or focal severity of coronary luminal disease, or both. For more than 50 years 1 the coronary angiogram has been used to define epicardial coronary disease. While conventional coronary ...

A computerized tomography (CT) coronary angiogram isan imaging test that looks at the arteries that supply blood to your heart. It might be done to diagnose the cause of chest pain or other symptoms. A CT coronary angiogram uses a powerful X-ray machine to produce images of your heart and ...

For patients with mild stenosis or normal coronary arteries, no further imaging studies were recommended. A recommendation for revascularization by percutaneous coronary intervention or coronary artery bypass graft (CABG) surgery was based on best clinical judgment of the treating physicians....
What is a CT angiogram? A cardiac CT angiogram is a less invasive version of the traditional angiogram. Utilising state of the art computer tomography scanners, it checks the arteries supplying blood to the heart, and can be used to diagnose conditions such as coronary artery disease (CAD). ...
A HeartFlowFFR-CT example showingcomparison with a CT scan of heavily calcified coronary arteries. The lesion looks severe anatomically on CT, but it not significant enough to qualify for stenting according to the FFR-CT. The CT imaging is sent to an outside vendor so it can be run through...
An electron beam CT scan is another special type of CT scan, which helps in detecting coronary artery disease and atherosclerosis. An electron beam CT scan is faster than a regular CT scan and it can also take good pictures of the coronary arteries while the heart is beating. Electron beam...
However, the accuracy of patient-specific coronary flow simulations depends on the quality of imaging upon which they are based. A common source of error is the exclusion of coronary arteries that are under-resolved by imaging. CFD models are often based on coronary computed tomography angiography...
Both found CTA can help determine if if a patient should be sent for a diagnostic angiogram, or if a non-invasive exam is good enough to determine if revascularization is needed.[13,14] "This is very relevant as we try to reduce the number of invasive coronary angiograms in a COVID-...
