This review outlines the current status and future potential of imaging and catheter-based modalities, such as SPECT, PET, and CMR, for assessing myocardial viability in left ventricular dysfunction.
This review summarizes the available modalities, including advanced imaging and endocardial mapping, for detecting viable myocardium to guide prognosis and treatment in left ventricular dysfunction.
Viability assessment informs LV dysfunction management; leaves open optimal modality selection pending prospective validation.
Detection of viable myocardium in patients with left ventricular dysfunction has become an increasingly important guide to prognosis and treatment. This article reviews the current status and future potential for the application of modalities to assess myocardial viability. Imaging and other techniques that are reviewed are myocardial perfusion imaging by single-photon-emission computed tomography, positron-emission tomography, echocardiography, cardiac magnetic resonance technology, computed tomography and catheter-based endocardial mapping.

Hamdan et al. (2006) conducted a review in Left ventricular dysfunction. Myocardial viability assessment modalities (SPECT, PET, echocardiography, CMR, CT, endocardial mapping) was evaluated. This review outlines the current status and future potential of imaging and catheter-based modalities, such as SPECT, PET, and CMR, for assessing myocardial viability in left ventricular dysfunction.
