Peak Mitral Inflow Velocity Predicts Mitral Regurgitation Severity

WebSecondary outcomes were the changes in left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), and the ratio of early mitral inflow velocity to atrial inflow velocity (E/A). Summary odds ratios were estimated using a fixed-effect or random-effect model. WebThe normal LVOT flow pattern is a laminar flow pattern during systole. The flow profile is a quick upstroke, followed by a smooth arc, which peaks in midsystole, and has a quick downstroke. The maximum velocity of the flow profile should peak at about 100 cm/sec or less. To measure the LVOT profile with PWD, the sample volume should be placed ...

The diagnosis of constrictive pericarditis was associated with greater respiration-related change in mitral E velocity (30.7±20.4% versus 13.7±17.0%; P <0.001; Figure 2) and a marginally greater ratio of deceleration time in expiration versus inspiration ( P =0.06).

WebNine (47%) of the 19 patients had less than 25% respiratory variation in E velocity. There was no significant difference in mitral inflow peak velocity, deceleration time, early-to-late ventricular filling ratio, and E' velocity between patients with and patients without respiratory variation of E velocity of 25% or more. WebIsovolumic relaxation time (IVRT) is a measure of time (in milliseconds) from the onset of the aortic valve closure spike artifact to the onset of the mitral valve opening spike artifact (Figs. 18-5 and 18-6 ). 17 The IVRT is obtained from the apical five-chamber view by aligning the Doppler beam midway between the LV inflow and the LV outflow ...
