PATIENT REPORTED OUTCOMES CAN BE PREDICTED BY CHANGE IN LEFT ATRIAL PRESSURE AND NOT CHANGE OF TRANSMITRAL GRADIENT FOLLOWING MITRACLIP

The association between the acute change in mean direct left atrial (LA) pressure and symptom improvement post MitraClip has been shown. Mean transmitral diastolic Doppler pressure gradient is routinely measured before and after MitraClip deployment and is used in assessing procedural success.
