How many cardiac cta (computed tomography angiogram) procedures are performed annually in small hospitals?

Thousands. Coronary cta mostly performed in cardiology offices. Many performed in hospitals also. Hundreds of thousands of these scans done each year. I read many of these tests a year. Very good technology.
I don't know. I did a brief search of relevant literature trying to get an answer for you but didn't come up with anything useful. I currently consult at a small hospital (100 beds) and we do about 30-50 a year, i would guess. New literature is promoting ccta in the er to rule out acute coronary syndrome quickly so patients can go home. If insurance picks up on that, the # of procedures will sky-rocket.

Is computed tomography angiogram cta a very common procedure?

CT angiogram. It is being done much more often when it is necessary to visualize blood vessels (for example to see if there's a blockage). There is some radiation involved but it is considered much less "invasive" and has less complications than the regular type of "angiogram", where blood vessels are visualized by inserting thin tubes called catheters directly into them to inject a dye.

Yes. Many done every day. Saves you from getting a diagnostic angiogram to diagnose your problem. Read more...
Yes. Many doctors will order this test first before a more invasive test such as a routine angiogram where a catheter is inserted into the blood vessel. Because this is a ct picture it may be unclear or llimited. If the results are unclear or show a problem you may get a routine angiogram to confirm any problems and perhaps get treatment at the same time. Read more...

What is the definition or description of: computed tomography angiogram cta?

Artery test. A special type of ct scan where intravenous dye is injected, and imaging is timed so that the arteries of interest are maximally opacified by the injected dye. Ct images in this test are acquired rapidly, and the actual scan will likely be done in a matter of seconds. Historically, evaluating the arteries required threading a catheter into the artery of interest. Cta is non-invasive. Read more...
