Microsphere retention and distribution in normal hearts and in hearts with 1- and 2-week-old MI. The retention is expressed as percentage of the total microspheres injected. Values <0.5% are shown as 0. (A) Moving from left to right in these hearts, the anterior wall is shown on the left side, followed by the septum, posterior wall, and lateral wall.

(B) When comparing endo- and epicardial distribution, in healthy hearts, significantly more retention of microspheres is found in the epicardium after retrograde infusion; this relation is reversed in 7-day-old MI, but in 2-week-old MI characterized by a transmural scar, retrograde infusion deposits more spheres in the epicardium than does transendocardial injection (Reproduced with permission of John Wiley and Sons, Inc. from ref. 10. © 2006.)
