This document addresses the use of myocardial strain imaging to detect subclinical cardiac dysfunction. Myocardial strain imaging is an additional analysis performed during conventional cardiac imaging (echocardiography or cardiac MRI). Myocardial strain imaging is theorized to be an improved sensitivity test over ejection fraction (EF) in monitoring ventricular function.

Notes:

• This document does not address cardiac imaging services including MRI. For criteria related to cardiac imaging, refer to applicable guidelines used by the plan.
