Can a pulmonary AV fistula be visualized on a coronary CTA angiography study? My cardiologist stated that a loud murmur was likely a pulmonary AV fistula. I had a coronary CTA angiography, which revealed a small accessory pulmonary vein draining into the left side of the left atrium, but nothing about a fistula in the report. I was just wondering if the coronary CTA angiography was the best diagnostic tool for a PAV or if my HMO only authorized this one study since the doc was trying to rule out other cardiac issues too? Any thoughts would be appreciated.
