Key result
Global left atrial strain assessed by two-dimensional speckle-tracking strongly predicted atrial fibrillation recurrence after successful ablation (4-chamber longitudinal strain HR 27.8, P<0.0005).

Does left atrial deformation imaging with 2D speckle-tracking predict the rate of recurrence of atrial fibrillation after successful ablation procedures in patients with paroxysmal and persistent AF?
Hazard Ratio: 27.8
p-value: p=<0.0005
Global left atrial strain assessed by 2D speckle-tracking echocardiography is a strong independent predictor of atrial fibrillation recurrence after successful ablation.
Hammerstingl et al. (2011) conducted an observational in Atrial fibrillation (n=133). Left atrial deformation imaging with two-dimensional speckle-tracking (2D-ST) vs. Matched controls / Patients maintaining sinus rhythm was evaluated on Atrial fibrillation recurrence (HR 27.8, p=<0.0005). Global left atrial strain assessed by two-dimensional speckle-tracking strongly predicted atrial fibrillation recurrence after successful ablation (4-chamber longitudinal strain HR 27.8, P<0.0005).
