Effects of different ablation strategies on long-term LA function as evaluated by speckle tracking analyses following the ablation procedures; (A,B) changes in LA peak systolic strain in two- and four-chamber views; (C,D) changes in LA peak systolic strain rate in two- and four-chamber views; (E,F) changes in LA peak early diastolic strain rate in two- and four-chamber views; (G,H) changes in LA peak late diastolic strain rate in two- and four-chamber views.
