The2009 American Society ofEchocardiography (ASE) andEuropean Association of Echo-cardiography (now EuropeanAssociation of CardiovascularImaging [EACVI]) guidelines fordiastolic function assessmentwere comprehensive, includingseveral two-dimensional (2D)

8 And Doppler parameters tograde diastolic dysfunction andto estimate LV filling , the inclusionof many parameters in the guide-lines was perceived to renderdiastolic function assessmenttoo complex, because severalreaders have interpreted theguidelines as mandating all thelisted parameters in the docu-ment to fall within specifiedvalues before assigning a specificgrade. The primary goal of thisupdate is to simplify theapproach and thus increase theutility of the guidelines in dailyclinical diastolic dysfunction isusually the result of impairedLV relaxation with or withoutreduced restoring forces (andearly diastolic suction), andincreased LV chamber stiffness,which increase cardiac fillingpressures.

9 Thus, when perform-ing an echocardiographic studyin patients with potential dia-stolic dysfunction, one shouldsearch for signs of impaired LVrelaxation, reduced restoringforces and increased diastolicstiffness. More important, LVfilling pressure should be esti-mated because elevated LV dia-stolic pressure in the absence ofincreased LV end-diastolic vol-ume is strong evidence in favorof well-developed diastolicdysfunction. In the majority of clinical studies, LV filling pressuresand diastolic function grade can be determined reliably by a fewsimple echocardiographic parameters with a high feasibility.

10 In addi-tion, technical developments have emerged that provide newindices that appear promising for studying LV diastolic update places more emphasis on applying the most useful,reproducible, and feasible 2D and Doppler measurements fromthe 2009 applying the guidelines, it is essential to consider what the termLV filling pressuresrefers to. The termLV filling pressurescan refer to meanpulmonary capillary wedge pressure (PCWP) (which is an indirect esti-mate of LV diastolic pressures), mean left atrial (LA) pressure (LAP), LVpre-A pressure, mean LV diastolic pressure, and LVend-diastolic pressure(LVEDP).
