Speckle tracking may identify risk of postoperative LV dysfunction in asymptomatic severe MR; hypothesis-generating and requires prospective validation before guiding surgical timing.
Does speckle tracking echocardiography predict postoperative LV dysfunction in asymptomatic patients with severe primary mitral regurgitation?
Myocardial systolic velocities and deformation assessed by speckle tracking can detect subclinical LV dysfunction and predict impaired postoperative LV function in asymptomatic patients with severe primary mitral regurgitation.
