The post-stress images in the VLA view (top
row) shows mild to moderate photopenia of the apex, infero-apical and
distal inferior wall and severe photopenia of the basilar half of the
inferior wall. This is best seen in the 10th frame.In comparison, the
resting images reveal near complete reversibility within the inferior
wall with mild persistent apical photopenia.
The 10th frame of the post-stress SA view (fifth
row of images) shows severe photopenia of the posterolateral wall with
near complete reversibilty in the resting phase (last row).
Thus, the study demonstrates reversible photopenia
or ischemia of the inferior and posterolateral wall. There is also a
mild area of fixed apical photopenia. One would expect to find disease
within the circumflex artery (which was not grafted) PLUS the saphenous
vein graft to the RCA (or the RCA diatal to the anastamosis).
The bulls-eye reconstructed images and the 2.5
standard deviation blackout plots, shown below, confirms the above findings.
