Abstract: ABSTRACT This study aims to introduce a new formula for pulmonary artery wedge pressure (PAWP) derived from the pathophysiology of Velocity A (VA) waves. The current formula is the the Nagueh formula. Left ventricular (LV) filling is described as a velocity A (Va) wave. The Va wave represents the filling rate of the end-diastolic blood phase from the left atrium (LA) to the LV which can be determined on echocardiography. Left ventricular end diastolic pressure (LVEDP) is equivalent to LA pressure and is also equivalent to PAWP. The gold standard method for obtaining PAWP values is right heart catheterization. By measuring the Va waves in the bloodstream, a new PAWP formula is obtained, and the PAWP examination can be validated in research and can be compared with several other PAWP formulas that are currently the world’s standard formula for calculating pulmonary artery wedge pressure (PAWP). The new PAWP formula is obtained from the conversion of the Va wave. This formula could be validated further in research and used in clinical practice. Keywords: Velocity A wave (Va wave), pulmonary artery wedge pressure (PAWP) formula.
