dc.description.abstractObjective: We investigated how velocity of isovolumetric relaxation period on pulsed-wave tissue Doppler trace (IVRa and IVRb) is affected by the left ventricular (LV) geometry changes. Methods: Two hundred cases without exclusion criteria were included in the study. Normal LV mass index (LVMI) and normal relative wall thickness (RWT) was assigned to group 1 (n = 72). Concentric remodeling (normal LVMI and increased RWT) was defined to group 2 (n = 25). Eccentric LV hypertrophy (LVH) (increased LVMI and normal RWT) was defined to group 3 (n = 62). And finally, concentric LVH (increased LVMI and increased RWT) was defined to group 4 (n = 41). Results: Patients with LVH (groups 3 and 4) were older than group 1 (P = 0.017 and 0.001). It was observed in the assessment of M-mode ECHO parameters that the aortic valve diameter, aortic valve opening, LV end-systolic diameter (LVESD), LV end-diastolic diameter (LVEDD), and left atrium (LA) were higher in cases with eccentric LVH. It was shown that Ea velocity and Sa velocity time integral (Sa-VTI) were decreased with LV geometry change. However, IVRa velocity and E/Ea were increased as LV geometry change. A positive correlation between IVRa velocity and LVMI (correlation ratio = 34%, P = 0.000) was found. Similarly, a positive correlation between IVRa velocity and RWT (correlation ratio = 17%, P = 0.025) was found. Conclusion: IVRa velocity exhibits a positive correlation with LV geometry changes indicating that IVRa velocity is affected by LV geometry like the other parameters influenced by LV geometry.
