The 3D reconstruction of the myocardial scar, including the core (orange) and gray (yellow) zones, superimposed by the EAVM data. The EAVM colors indicate: healthy myocardium (pink), core scar (red), and gray zone (intermediate colors). a is from the SRR volume, and b is from the SA volume.

Figure 2: The 3D reconstruction of the myocardial scar, including the core (orange) and gray (yellow) zones, superimposed by the EAVM data. The EAVM colors indicate: healthy myocardium (pink), core scar (red), and gray zone (intermediate colors). a is from the SRR volume, and b is from the SA volume.

Mentions: The SRR volume achieved increased resolution in the through-plane direction (Figure 1). Compared to the SA volume, the SRR volume resulted in significantly reduced scar size estimation for both scar core zone (9.6 ± 7.8 ml vs. 8.7 ± 8.3 ml, p < 0.05) and gray zone (11.9 ± 8.2 ml vs. 7.9 ± 6.0 ml, p < 0.05). Average EAVM bipolar voltage for SRR and original SA volume were in normal myocardium 3.7 ± 3.3 mV versus 3.8 ± 3.3 mV (p = NS); in scar core 0.8 ± 0.6 mV versus 1.0 ± 1.0 mV (p = 0.04) and scar gray zone 1.2 ± 0.8 mV versus 1.6 ± 1.7 mV (p = 0.005). SRR volumes showed better agreement with EAVM (Figure 2).
