Mean perfusion score(plateau video intensity times the wash-in rate) was lower in segments that were supplied by obstructed coronary arteries in real time(7.5 vs 22.6 dB/s, p< 0.005) and with end-systolic triggering(8.6 vs 20.9 dB/s, p< 0.001). Lower mean septal perfusion scores(< 12 dB/s) were seen in 14 of 16 patients who had obstructive septal coronary artery disease, and normal mean septal perfusion scores were seen in 6 of 7 patients who did not have obstructive septal coronary artery disease.展开更多
