摘要: Background Predicting early reconnection/dormant conduction (ERC) immediately after pulmonary vein isolation (PVI) can avoid a waiting period with adenosine testing. Objective To identify procedural and biophysical parameters predicting ERC. Methods Consecutive atrial fibrillation (AF) patients undergoing first cryoballoon ablation (Arctic Front Advance) between 2014 2017 were included. ERC was defined as manifest or dormant (PV) reconnection 30 minutes PVI. Time to (TTI), balloon temperatures (BT), thawing times evaluated potential predictors for Based on multivariable model, cut-off-values formula constructed be used in clinical practice. Results A total of 136 (60 ± 10 years, 96 male, 95% paroxysmal AF) found 40 (29%) (ERC group) 53 575 (9%) veins.
