Key result
Left atrial dyssynchrony time measured by tissue Doppler imaging was identified as an independent predictor of atrial fibrillation recurrence after pulmonary vein isolation.
Why the study?
Does left atrial dyssynchrony time measured by tissue Doppler imaging predict atrial fibrillation recurrence in patients undergoing pulmonary vein isolation?
Does left atrial dyssynchrony time measured by tissue Doppler imaging predict atrial fibrillation recurrence in patients undergoing pulmonary vein isolation?
Answers are grounded in this paper and cite their sources.
Left atrial dyssynchrony time measured by tissue Doppler imaging is a promising marker for predicting atrial fibrillation recurrence after ablation, though wider validation in prospective multicenter trials is necessary.

Kumar et al. (2015) conducted an editorial in Paroxysmal and persistent atrial fibrillation (n=200). Left atrial dyssynchrony time measured by tissue Doppler imaging vs. Healthy controls or patients without atrial fibrillation recurrence was evaluated on Atrial fibrillation recurrence (HR 1.69 per ms, p=<0.001). Left atrial dyssynchrony time measured by tissue Doppler imaging was identified as an independent predictor of atrial fibrillation recurrence after pulmonary vein isolation.
