Key Points

To review the potential etiologies and clinical implications of transient left ventricular dilatation observed during myocardial perfusion imaging.
Evaluation of clinical, hemodynamic, and technical factors associated with left ventricular cavity enlargement during myocardial perfusion studies.
Transient left ventricular dilatation is linked to severe multivessel coronary artery disease and diffuse subendocardial ischemia.
Technical factors, including resolution effects and imaging artifacts, can also produce an appearance of transient chamber enlargement.

Implication

Transient LV dilatation during MPI may reflect identifiable causes; Level 5 data leaves open its diagnostic or prognostic role pending prospective validation.
