Echocardiographic estimation of pulmonary artery wedge pressure: invasive derivation, validation, and prognostic association beyond diastolic dysfunction grading
Aims: Grading of diastolic function can be useful, but indeterminate classifications are common. We aimed to invasively derive and validate a quantitative echocardiographic estimation of pulmonary artery wedge pressure (PAWP) and to compare its prognostic performance to diastolic dysfunction grading.Methods and results: Echocardiographic measures were used to derive an estimated PAWP (ePAWP) usingAims: Grading of diastolic function can be useful, but indeterminate classifications are common.
