“In my opinion, CTCA does have added value in the diagnostic process, it is less invasive than coronary angiography, and can provide more clarity in the cardiac symptoms experienced by patients,” Mommersteeg suggested.
A November, 2016,
study had shown that CT proved a relatively safe approach to making a diagnosis in patients presenting with atypical angina or chest pain before performing invasive coronary angiography.

“CT increased the diagnostic yield and was a safe gatekeeper for coronary angiography, with no increase in long-term events,” Marc Dewey, Heisenberg professor of radiology at the Charité-Universitätsmedizin Berlin, Humboldt-Universität and Freie Universität zu Berlin in Germany and colleagues reported in the
British Medical Journal.
They found that “the length of stay was shortened by 22.9 hours with CT, and patients preferred noninvasive testing.”
“Cardiac CT reduced the need for coronary angiography from 100 percent to 14 percent,” the researchers reported. Coronary angiography did provide significantly more information needed to make a diagnosis – 75 percent, versus just 15 percent for CT.
