Overview

• Myocardial viability studies can determine whether hypocontractile myocardium is viable but just hibernating, and could therefore benefit from revascularization.

• Common imaging modalities to assess myocardial viability include:

• Dobutamine echocardiography
• Nuclear tests (SPECT or PET)
• Cardiac MRI
