myocardial viability assessment
Evaluation of dormant but recoverable heart muscle tissue to guide revascularization decisions.
Full Definition
A comprehensive evaluation using various imaging modalities to determine whether apparently non-functioning myocardium retains the potential for functional recovery following revascularization. Methods include dobutamine stress echocardiography, cardiac MRI with late gadolinium enhancement, nuclear perfusion imaging, and positron emission tomography. This assessment is crucial for determining whether patients with reduced left ventricular function would benefit from revascularization procedures rather than medical management alone.
Usage
Usage note: Specify imaging modality used and quantitative results when available.
In Context
- "Myocardial viability assessment showed extensive hibernating tissue in the anterior wall." — Pre-procedural evaluation
