A new simplified method for calculating mitral pressure gradient was proposed, i.e., mean MVPG = MLAP \u2013 LVEDP\/2, where MLAP is mean left atrial pressure, and LVEDP is left ventricular end\u2010diastolic pressure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>MVPGs derived from the standard and the new method were 13.28 \u00b1 7.42 mm Hg and 13.50 \u00b1 7.93 mm Hg, respectively, and there was no significant difference between the values of these two methods (<jats:italic>P<\/jats:italic> = 0.065). The MVPG derived from the new simplified method correlated closely with that calculated by the standard approach (<jats:italic>r<\/jats:italic> = 0.975, <jats:italic>P<\/jats:italic> &lt; 0.001).
