ITV sous aortique

English translation: subaortic velocity time integral

GLOSSARY ENTRY (DERIVED FROM QUESTION BELOW)
French term or phrase:ITV sous aortique
English translation:subaortic velocity time integral

French to English translations [PRO]
Medical - Medical (general) / cardiac ultrasound
French term or phrase: ITV sous aortique
In a report on information from a trans-thoracic cardiac ultrasound and a trans-oesophageal ultrasound:

"VG: FRS = 25%, hypokinésie globale, septum paradoxal, ITV sous aortique = 12 cm, FC = 110/,min, électroentrainé. "

The nearest finding so far is "intégrale par temps/vitesse" which seems to be "flow/velocity integral" in English. But I'm not convinced this is correct and would appreciate some expert opinions. Any suggestions welcomed. TIA.

Thank you all.
Notes to answerer
Asker: Thanks very much, Liz, Zareh, Sue and Maurice. I Googled the three alternatives ("velocity-time integral", "time-velocity integral" and "flow-velocity integral" together with "cardiac ultrasound" and, while they are all in use, "velocity/time integral" is far and away the most commonly used. So that's the one I'll go with. Many thanks indeed.

agree  Zareh Darakjian Ph.D.: Seems right to me. Since velocity has units of cm/s, then the integral will effectively multiply it by time (s) and the unit left will be cm.

agree  Dr Sue Levy (X): also time-velocity integral TVI (same thing) but VTI more common

Explanation:
The following is a description of velocity time integral: Of course, an integral is a sum or also an average, in this case of velocities. The sum of velocities is distance. But some medical textbooks may use cm/s for a sum of velocities... but that's not the issue here. What we are concerned with is what this is called:



**Velocity Time Integral:** The blood flow and velocity are phasic in the circulation because of the change throughout the cardiac cycle. A Doppler spectrum of the velocity of blood through a valve will yield a curve that has velocity (cm/s) on the y axis and time (s) on the x axis. When this curve is integrated, it yields a velocity-time integral (VTI) in units of centimeter (cm/sec x sec = cm). It indicates the distance the blood travels during a certain cardiac circle. The product of VTI (cm) and CSA (cm 2) will yield volume (cm3). The SV through the LVOT area equals the SV through the AS area. The VTILVOT and the VTIAS can be determined using the Doppler spectrum of the velocity of blood through the LVOT and the AS area based on PWD or CWD measurement, respectively. Volume Continuity: Volume = area x VTI (ml) CSALVOT x VTILVOT = CSAAS x VTIAS CSAAS = CSALVOT x VTILVOT / VTIAS

agree  liz askew: Very nice too! I might have to read this when my brain is less tired...It amazes me that there are people who can understand this - just as well really ;)

  -> Thank you. The abbreviations are scary, but the bottom line is velocity x cross sectional area = volume per unit time. From here, one can get the stroke volume and all kinds of other goodies...

subaortic FLI (flow velocity integral)


Explanation:
Related to Doppler blood flow measurement. "The flow velocity integral reflects the average velocity of the red cells during systole." This is a maths formula. It works out as a distance expressed in cm (v/t). Subaortic - self explanat.
