FIGURE 3.

Examples of ML-score map with optimal LV pacing site location in personalized ventricular models. Two color maps of the ML-value are shown on the LV surface of personalized models and on the LV AHA segment schemes. Dark gray at the AHA LV scheme marks segments containing postinfarction scar, which are excluded from pacing. Shades of red show LV surface area with ML-scores > 0.5 and shades of blue show ML-scores < 0.5. Blue and red dots show the locations of the clinical and optimal LV pacing sites. From left to right are shown examples of the ML-score map in a clinical responder (patient #2), non-responder (patient #1), and non-responder (true negative at the ref-PS) predicted as positive to CRT response at the optimal ML-based lead position (patient #7).
