Cardiac computed tomography angiography (CTA) combines X-ray images and computer modeling to produce three-dimensional views of a person's heart, to diagnose coronary artery disease or evaluate the individual's risk for the disease.
At Penn State Hershey, using a Seimens Definition Dual 64 CT scanner, cardiologists and radiologists work together to perform and interpret the cardiac CTA studies. These studies provide the clearest, non-invasive images of the heart, including the coronary arteries, of any imaging modality currently available.
Please review the checklist below for the correct indications to request a cardiac CTA for patients with the following or in the following circumstances.
- Equivocal or uninterpretable stress test
- Chest pain or angina equivalent (intermediate pre-test probability of coronary artery disease or unable to exercise, or no change in electrocardiogram and negative serial enzymes)
- Known coronary artery disease, chest pain, and uninterpretable stress test
- Symptoms and known coronary artery disease (i.e. post-stent or post coronary artery bypass surgery)
- Suspected congenital anomalies of coronary circulation
- Prior to non-coronary artery surgery (i.e., valve or aortic surgery)
- To assess pulmonary venous anatomy
- New onset heart failure, assess etiology
- Cardiac mass
- Technically limited images from echocardiogram, MRI, or TEE
- Pericardial conditions (mass, constriction, post-cardiac surgery)
- Before repeat cardiac surgery (i.e., to define coronary artery anatomy)
Call us (1-877-467-7484) if you would like to discuss the appropriateness of scheduling a cardiac CTA.
To order a test, please open and complete the request form below and fax it to the number at the bottom of the form. A cardiac CTA physician from Penn State Hershey will review the request and call you back to discuss the case.
Video description: With some of the most sophisticated scanners and powerful post-processing workstations currently available, the ability of imaging experts at Penn State Hershey Heart and Vascular Institute and Radiology to see the heart and the coronary arteries is extraordinary. Quick, detailed evaluation of the coronary arteries can be accomplished as an outpatient, with little radiation or discomfort to the patient.
Cardiac CTA allows physicians to be able to see the structure of the heart, with a non-invasive technique. At Penn State Hershey, cardiologists and radiologists work together to perform and interpret the cardiac CTA studies.
While cardiac CTA provides a clear, three-dimensional view of the heart, it is not yet recommended for all patients. Please talk with your physician to find out if this study is right for you.
