If only . . . we get an image like this , echo can help rule out most left main disease with conviction .
Have a close look at it ! One can get a good image of coronary ostia in short axis view . But , here it is well visualized in long axis .
I tried to put color flow within left main .
What about pulsed Doppler across left main ?
After all it needs 2mm sample volume and this left main was near 4.5mm . So keep trying !
