| Canine Preparation with
C-Arm X-Ray System, Wayne State University, Detroit, MI (1993).
Canines are placed on their right side. All views are anterior
(oblique), with the red background representing the back, and
left-to-right the cranio-caudal direction.
In the reconstructions below the visible structure represents the left ventricle (the right ventricular blush is too faint to be visible). Left-to-right is the cranial-caudal direction, as seen from the cardiologist.
of 50% Ligation of LAD. Images are at Systole.
Upper Renditions w/o Ligation, left to right: complete myocardium, frontal cut-away, and upper cut-away during normal perfusion and with contrast dye supplied to the LAD and posterior coroanry arteries.
Lower Renditions with 50% Ligation of the LAD. Otherwise same as upper renditions.
Reconstruction is from 6 x-ray projective views at 30 degree increment. Observe increased blush-intensity in the area near the LAD artery (upper-left in each image) (1993-1994).
of Selective Posterior Coronary Dye Injection.
Left column: control with dye injection into both coronary arteries. Renditions top to bottom: complete myocardium, frontal cut-away, and upper cut-away.
Right column: selective dye injection into posterior coronary artery. Renditions top to bottom: complete myocardium, frontal cut-way, and upper-cut-away at the level of the posterior coronary (1993-1994).
