Help! what is abnormal mitral annular velocity pattern by tissue dopper imaging?

Diastolic dysfunctio: It is a sign of abnormal filling during the resting phase of the cardiac cycle (diastole). It may be just impaired relaxation (the mildest form) or actually indicative of different degrees of restricted filling. There are 4 recognized stages. The mildest is extremely common and present in most people >age 40. The 4th stage is extremely rare and present only in rare diseases like cardiac amyloid.
