Abstract
OBJECTIVE: Although American and European consensus statements advocate using the ratio of the transmitral E velocity and tissue Doppler early diastolic mitral annular velocity (E/e') in the assessment of left-sided heart filling pressures, recent reports have questioned the reliability of this ratio to predict left atrial pressures in a variety of disease states. The authors hypothesized that there is a clinically significant correlation between E/e' and pulmonary capillary wedge pressure (PCWP) in patients with severe aortic stenosis.
DESIGN: Retrospective cohort study.
PARTICIPANTS: The study comprised 733 consecutive patients with severe aortic stenosis who underwent transcatheter aortic valve replacement for severe aortic stenosis.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: PCWP and E/e'
CONCLUSION: A clinically relevant relationship between E/e' and PCWP was not observed in patients with severe aortic stenosis.
