May help detect subclinical LV dysfunction before mitral valve surgery; extends prior strain data but leaves open clinical adoption.
Does preoperative regional myocardial peak systolic strain rate predict postoperative LV systolic function in patients with severe mitral regurgitation undergoing valve surgery?
Preoperative strain rate imaging, especially when corrected for end-diastolic volume, can accurately detect subclinical left ventricular dysfunction and predict postoperative ejection fraction in patients with severe mitral regurgitation.
Marciniak et al. (2011) studied this question.
