From: Correlation of DTI tractography with electroanatomic mapping in normal and infarcted myocardium
Whole hearts show that PA values in (A) a normal sheep heart ex vivo are similar to those seen in (B) a normal human heart in vivo during systole. (C) Tracts of an infarcted sheep heart color-coded by PA show that PA is significantly increased in the infarct zone. (D) Tractograms color-coded by bipolar voltage show that regions of low voltage correlate well with regions of high PA. The microstructural and electrical transitions between normal myocardium, border zone and infarct can be clearly seen. The inset displays the original bipolar voltage map and measurement locations.
