Background: There is no single noninvasive index that can directly assess diastolic function. Untwist, contributes to diastolic suction, early filling. Speckle tracking imaging (STI), can be used to study the relation between diastolic indices and untwist in patients with diastolic dysfunction.

Patients and methods: 75 patients with diastolic dysfunction and 25 normal volunteers were selected for this study. According to mitral flow pattern they were classified into Group I (abnormal relaxation), Group II (pseudo-normalized) and group III (stiffness pattern) Using STI, the basal and apical short axis views were imaged. Stored data were processed to get apical and basal rotation, systolic twist, peak systolic twist ratio, diastolic untwist ratio... view more»
