Conclusion
Pre-ablation assessment of LA-PLSsys seems to be a significant predictor
of AF recurrence after CA. However, current data do not permit
derivation of a reference range with adequate positive and negative
predictive value. More studies, using stricter methodology and also
including patients at high risk for recurrence- such as those with
severely dilated LA- are needed to clarify the clinical use of
LA-PLSsys.
