What is the clinical utility of echocardiographic strain in the diagnosis and prognosis of cardiac disease?
Echocardiographic strain is used to evaluate cardiac dysfunction in patients with coronary artery disease, valvulopathies, cardiomyopathies, and cancer treatment–associated cardiac dysfunction. This review presents an array of speckle-tracking echocardiographic images of characteristic bull’s-eye plots that can be used to inform the differential diagnosis and prognosis for these common cardiac conditions.
The pattern of the bull’s-eye plot can be used by clinicians as a diagnostic and prognostic tool in contemporary patient care for a variety of cardiovascular conditions.
Myocardial deformation or strain by speckle-tracking echocardiography (STE) has become an established echocardiographic modality for the diagnostic and prognostic evaluation of cardiac dysfunction. Current literature supports the incremental value of strain in diagnosis, risk stratification, and prognostication of a multitude of cardiac disease states.
Strain has been studied across the clinical spectrum from common to obscure pathologic conditions. This review presents the current literature evaluating characteristic strain patterns across this clinical spectrum, discusses prognostic implications, and provides a case series of classic strain polar maps, which are also known as bull’s-eye plots.
Conclusions and Relevance
Characteristic bull’s-eye patterns can be used to guide patient evaluation and management.
