Atrial fibrillation is associated with profound structural and functional changes in the atria. In the present study, the authors investigated the association between left atrial phasic function and the extent of left atrial fibrosis using advanced cardiovascular magnetic resonance imaging techniques, including 3-dimensional late gadolinium enhancement and feature tracking.
Recognize that an impaired passive LA function (conduit and reservoir strain) can be an expression of extensive LA fibrosis, which might possibly have implications for the succesrate of an PVI ablation procedure.
To close the gap outlined above:
1. Learners need to know about the relation between LA strain and LA fibrosis.
2. Learners need to know how to apply and assess atrial strain analysis in patients scheduled for an PVI ablation procedure.
3. Learners need to consider performing atrial strain analysis to get insight into the status of left atrial remodeling in AF patients.
