Left atrial strain, intervendor variability, and atrial fibrillation recurrence after catheter ablation: A systematic review and meta-analysis.

The aim of this systematic review and meta-analysis is to investigate the capacity of preinterventional left atrial strain (LAS) to predict AF recurrence (AFR) after catheter ablation by using all relative published data. Intervendor variability regarding different ultrasound stations and strain analysis software suites was taken into consideration. The research was performed according to PRISMA guidelines.
