Hebrew to English Medical Medical: Cardiology Hospital Release Report

This is under a section labeled Pressures and the full line reads -- מפל שיא על פני המסתם האורטלי: 0

Pressures:
Aorta 166/69/(101)
Left ventricle before the injection 166/12
מפל שיא on the surface of the aortic valve: 0

Is this a record waterfall on the surface of the aortic valve?

Thanks!
