WebBefore TAVR, the LV diastolic waveform has a normal-appearing filling pattern with LVEDP of 20 mm Hg. After TAVR, there is an elevated plateau of diastolic pressure with a new appearance of an early dip consistent with a restrictive filling pattern (panel A(ii)). Web3 iun. 2024 · The LVEDP represents the pressure created by the volume in the left ventricle at the end of diastolic when the mitral valve is open. LVEDP is estimated from the PAOP mean value and the left atrial waveform at end-diastole.
