Key result
Intraoperative coronary ultrasound closely correlates with angiographic estimates of percent obstruction.

Does intraoperative ultrasound scanning of coronary arteries accurately evaluate coronary atherosclerotic lesions compared to angiography in patients undergoing cardiac surgery?
Effect estimate: r = 0.91
Intraoperative ultrasound scanning of coronary arteries provides accurate evaluation of atherosclerotic lesions, correlating closely with angiography, and may aid in saphenous vein graft placement.
Sahn et al. (1982) conducted an observational in Coronary artery disease (n=31). Intraoperative ultrasound scanning of coronary arteries vs. Coronary angiography was evaluated on Correlation of ultrasonic appearance of coronary lesions with angiographic estimates of percent obstruction (r = 0.91). Intraoperative ultrasound scanning of coronary arteries closely correlated with angiographic estimates of percent obstruction (r = 0.91).
