MI reconnections and repeat procedure
The reconnection sites were evaluated by electrogram sequences of the left atrial myocardium and CS musculature recorded inside the CS under LAA pacing.15 If the electrograms showed an endocardium reconnection pattern, RF applications were delivered to the endocardium (Figure 3B). In the case of epicardial reconnection pattern, we first tried EIVOM, and subsequently ablated inside of the CS. In the case or AT, we estimated MI endocardium reconnections using an activation map that was created using an AdvisorTM HD grid-mapping catheter.
