N2 - This study evaluated an analogue laser optical disc (MVP) as an alternative for cinefilm angiography in the visual analysis of coronary angiograms. Visual analysis was performed independently by 5 observers using cinefilm and MVP before and after PTCA (194 coronary lesions in 88 patients) and the outcomes were compared with QCA. The mean percentage diameter stenosis on cinefilm and MVP yielded similar results compared to QCA. Regression analysis showed a good correlation between the mean cinefilm and MVP values per diameter stenosis (p < 0.001). Bland-Altman plots confirmed these findings. Qualitative analysis for detection of coronary dissections after PTCA showed an incidence of 31.3% (cinefilm) and 21.8% (MVP) (p < 0.05). The results of this study indicate that the visual analysis of the coronary angiograms using the analogue laser optical disc (MVP) yields similar results compared to the cinefilm concerning coronary lesion severity, although there is an underestimation of coronary dissections.
