Characteristics of the myxoma would include its size, the site of attachment and it is prolapsing or not. However, the hemodynamic alteration of left ventricular (LV) filling where

Although the pressure gradient is a practically useful parameter to evaluate the severity of stenotic valve lesions, it essentially depends on flow rate. For a given stenotic orifice, it may vary with the changes in the hemodynamic state of the heart, and not be simply regarded as an absolute measure of the obstruction.
