Incremental value of left atrial strain to predict atrial fibrillation recurrence after cryoballoon ablation
<h4>Objective</h4> Atrial fibrillation (AF) recurrence occurs in approximately 25% of the patients undergoing cryoballoon ablation (CBA), leading to repeated ablations and complications. Left atrial (LA) dilation has been proposed as a predictor of AF recurrence. However, LA strain is a...
