Conclusions
RECURRENCE, CONTRACTION
LA function in LSPAF improves after AF ablation as shown by a reduction in LA volumes, improved LAEF, better reservoir function and recovery of atrial contraction. Reduced LASct following the blanking period is the only independent predictor of AF recurrence. Further studies are needed to review ablation outcomes based not only on LA structure but also on LA function, particularly LASct, which might lead to improved ablation success.
