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 ... WebNormal TIPS velocity ranges from 90-190 cm/sec. Velocity >190 cm/sec is diagnostic of stenosis, with a drop in flow distal to a stenosis. Here in this case the velocity exceeds 280 cm/sec.
