Validation Study of the Accuracy of E/e' in Estimating Left Ventricular Filling Pressure

Validation Study of the Accuracy of E/e' in Estimating Left Ventricular Filling Pressure

The non-invasive estimation of left ventricular end diastolic pressure (LVeDP) is a main goal for performing an echocardiography in the routine clinical practice. Conflicting evidence exists about mitral E/e' ratio reliability for predicting high LVeDP

Inclusion Criteria:

• Age over 18 years
• Patient performing an echocardiography in the routine clinical practice
• Informed consent given

Exclusion Criteria:

• Severe valve disease, valvular prostheses, calcification of the mitral valve, the history of myocardial infarction, atrial fibrillation, severe arrhythmias not allowing the Doppler analysis, pacemaker and any image by inadequate Doppler ultrasound
• Major person under legal protection (backup justice, trusteeship, guardianship), person deprived of liberty.
