Key result
Lower peak atrial longitudinal strain measured by speckle tracking echocardiography independently predicted the development of postoperative atrial fibrillation (13.9% vs 24.8%; P<0.001).
Why the study?
Does left atrial longitudinal strain measured by speckle tracking echocardiography predict the development of postoperative atrial fibrillation in patients undergoing mitral valve surgery?
Observational (n=53)
Does left atrial longitudinal strain measured by speckle tracking echocardiography predict the development of postoperative atrial fibrillation in patients undergoing mitral valve surgery?
Absolute Event Rate: 13.9% vs 24.8%
p-value: p=< 0.001
Left atrial longitudinal strain measured by speckle tracking echocardiography is an independent predictor of postoperative atrial fibrillation following mitral valve surgery.

May support atrial strain for postoperative atrial fibrillation risk stratification after mitral valve surgery; hypothesis-generating pending prospective validation.
Candan et al. (2013) conducted an observational in Severe mitral regurgitation (n=53). Speckle tracking echocardiography (STE) was evaluated on Postoperative atrial fibrillation (POAF) (p=< 0.001). Lower peak atrial longitudinal strain measured by speckle tracking echocardiography independently predicted the development of postoperative atrial fibrillation (13.9% vs 24.8%; P<0.001).
