Incidence and predictors of periprocedural cerebrovascular accident in patients undergoing catheter ablation of atrial fibrillation.
Cerebrovascular accident (CVA) is a serious complication of catheter ablation of atrial fibrillation (AF). The incidence and clinical predictors of periprocedural CVA in patients undergoing AF ablation are not fully understood. ⋯ Despite periprocedural anticoagulation and transesophageal echocardiography, we found a 1.4% incidence of periprocedural CVA in AF ablation patients. A CHADS(2) score > or = 2 and a history of CVA are independent predictors of CVA after AF ablation. The CVA risk is low in patients with CHADS(2) score of 0.

Atrial fibrillatory wall motion and degree of atrial remodeling in patients with atrial fibrillation: a tissue velocity imaging study.
The atrial fibrillation cycle length (AFCL) and the intracardiac atrial electrogram morphology may be used to characterize atrial fibrillation (AF). However, assessment of these parameters requires an invasive electrophysiological study. We assessed clinical and electrophysiological correlates of noninvasive tissue velocity imaging (TVI) of the right and left atrial myocardial fibrillatory wall motion. ⋯ TVI of the atrial fibrillatory wall motion may enhance noninvasive characterization of atrial remodeling in patients with atrial fibrillation.
