In cardiac catheterization (often called cardiac cath), a very small hollow tube, or catheter, is advanced from a blood vessel in the groin or arm through the aorta into the heart. Once the catheter is in place, several diagnostic techniques may be used.
About Cardiac CTA A cardiac CTA is a scan of the chest that focuses on the heart. We use a 64 slice scanner that provides pictures with pixel size of 0.6 mm. This allows us to obtain 3-D images of the heart with unsurpassed detail. The scan produces images of the coronary arteries which are the vessels involved in heart attacks. The purpose of the test is to find blockages of these arteries, a condition known as coronary artery disease. Remarkably, this technology takes pictures of the coronary arteries without having patients undergo the risk of an invasive cardiac catheterization. When Should I Have a Cardiac CTA?
