Key result
Peak systolic torsion assessed by 2D-STE was higher in class II than class I MMVD dogs (P<0.001), but lower in class III than class II (P=0.001) and healthy controls (P=0.003).
Why the study?
Does two-dimensional speckle-tracking echocardiography reveal differences in left ventricular torsional deformations among clinical classes of myxomatous mitral valve disease in dogs?
Observational (n=83)

p-value: p=<0.001
Torsional deformations assessed by 2D-STE differ among clinical classes of MMVD in dogs, suggesting it may provide a detailed assessment of myocardial contractile function.

Torsion differences may signal evolving myocardial dysfunction in canine MMVD; leaves open whether 2D-STE refines staging or prognosis.
Suzuki et al. (2012) conducted an observational in Myxomatous mitral valve disease (n=83). Two-dimensional speckle-tracking echocardiography (2D-STE) vs. Healthy controls and different MMVD classes was evaluated on Peak systolic torsion (p=<0.001). Peak systolic torsion assessed by 2D-STE was higher in class II than class I MMVD dogs (P<0.001), but lower in class III than class II (P=0.001) and healthy controls (P=0.003).
