Purpose of Review
Two-dimensional (2D) echocardiography and Doppler echocardiography are important tools for cardiac evaluation unfortunately affected by artifacts, which can obscure pathology. Certain artifacts may be inevitable, but others can be diminished by changing the probe position.
Common 2D imaging artifacts include shadowing and enhancement. There are a variety of reverberation artifacts, ranging from comet tail to mirroring, that result in atypical duplication. At the same time, device and electronic interference create unique interference patterns. Doppler imaging has its own specific artifacts. These can alter spectral graphs, such as aliasing, or be seen on color Doppler imaging, such as pseudoflow or blooming.
Misinterpreting artifacts can result in improper management; thus, recognition is crucial. However, some artifacts can even be beneficial for evaluation and decision-making. We provide a review of artifacts in 2D and Doppler echocardiography for this reason.

This highlights the recognition of a previously disregarded side-lobe artifact as indicative of severe mitral regurgitation. Presence of splay can be utilized when regurgitant jet is not revealing or other indicators of mitral regurgitation are equivocal.
