WebVariability of LVOT VTI during breathing cycle was significantly higher in responders compared to non-responders 14% (± 5.9) and 6.48% (± 12.9), respectively (p<0.001). ROC analysis showed AUC 0.881 (95% CI 0.744–1.0, p<0.001), the best cut off value was 10% with 83.3% sensitivity and 85.7% specificity. 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 ...
