The ASE/EACVI grading system for diastolic function contains ambiguous guidelines and cutoff points that may misclassify patients as both sicker and healthier than they are.
The article critiques the new ASE/EACVI grading system for diastolic dysfunction, highlighting its ambiguities and potential for patient misclassification.

New ASE/EACVI diastolic grading ambiguity risks inconsistent LV pressure estimates in practice; leaves open need for clearer validated criteria.
Quantitation of diastolic function centers on the assessment of active and passive ventricular properties, and involves measurement estimates of ventricular relaxation, and chamber and myocardial stiffness. Diastolic dysfunction is a propensity to develop increased left ventricular (LV) end-diastolic pressure. Recently American Society of Echocardiography and European Association of Cardiovascular Imaging (ASE/EACVI) proposed a new grading system. While the new guidelines are ambiguous and with cutoff points that may misclassify patients as both sicker and healthier than they are. This article outlines the pathophysiology behind the diastolic dysfunction and role and limitation of echocardiographic assessment in predicting LV diastolic dysfunction.

Popović et al. (2018) conducted a review in Diastolic dysfunction. ASE/EACVI grading system for diastolic function was evaluated. The ASE/EACVI grading system for diastolic function contains ambiguous guidelines and cutoff points that may misclassify patients as both sicker and healthier than they are.
