Deformation imaging of the atria using 2D strain: A noninvasive modality to characterize operating compliance?

This viewpoint with two illustrated case summaries of biventricular and biatrial mechanical function/dysfunction emphasizes the importance of continued research in deformation imaging beyond the left ventricle, as there are no Cinderellas in the heart and we just cannot afford to be nonchalant toward the atria, particularly the right atrium.
