Significant differences exist in both amplitude and timing of AM events between the mitral and tricuspid annuli, likely reflecting intrinsic anatomical and electromechanical differences between both sides of the heart that require further investigation.

Our data reveal that mechanical systolic functions of the atria and the ventricles are more closely coupled on the right than on the left side of the heart. Whether this is a result of anatomic linking or chamber geometry will require further study.

This analysis provides a range of normal variables of RV size and function, not previously published, that can be used in routine evaluation and follow-up of patients with PH.
