In transesophageal echocardiography (TEE), the pressure halftime (PHT) measured in the transgastric 5-chamber view can quantify aortic regurgitation severity, where a PHT of 280-290 milliseconds indicates moderate AR; accurate measurement requires optimal alignment and image quality in deep transgastric views.

#Transgastric measurement of the #pressurehalftime - measuring #AR in #TEE 🫀#echocardiography #phtAdded:
in T in the transastric views you can also evaluate vertical regurgitation here we have an example of a measurement of the pressure half time in AR so you can utilize that in the TTE study in a fivechamber view and also in an apical long axis view in the TE study you have to go to measure this specific measurement into the transastric view sometimes deep transastric where you can see the five chamber view also the transastric long axis here. In this case, you have a pressure half time of around 280 290 milliseconds, which would point towards moderate AR. Be aware of optimal alignment and image quality to visualize it correctly.
