Ratings and Reviews

Just wrong informations for present time.

Guideline-based comprehensive resource


Clinical disorder videos freeze-frame to point out the echo findings. Figures are detailed. Best pocket reference that I have found regarding echo criteria for severity of valvular heart disease and diastolic function parameters. Other reviewer commented on PSAX base view being mislabeled, but it is labeled correctly. Have not come across any inaccurate info. Strongly recommend.

Nice app. Handy to have.


Good overall review of structures/images. Well done. One recommendation I would have is to have a section or subsection under mitral valve on identifying which scallop you are visualizing. This is something I always have to review/look up.
