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.
