Echocardiographic left ventricular (LV) diastolic function assessment represents one of the mainstays for routine, comprehensive transthoracic echocardiography in adults. Estimation of LV filling pressures is an integral part of LV diastolic function evaluation. Additionally, LV diastolic function assessment is crucial for the study of subjects with potential heart failure with preserved LV ejection fraction. Beyond the “old” LV diastolic function parameters, to date, mostly strain-based (and generally artificial intelligence-assisted) additional “new” echocardiographic techniques have emerged to optimize the study of LV diastole. The purpose of the present narrative critical review is to report and discuss the optimal echocardiographic assessment of LV diastolic function in light of the recent literature, with the aim of trying to outline the gaps in the current evidence in view of future developments. To date, multiparametric diastolic evaluation and grading seem advisable, using as many “old and new” measurements as possible—associated with their adequate selection related to the patients’ comorbidities—aiming to cumulatively increase the advantages of diastolic parameters and possibly minimize their limitations. Taking into account the considerable number of echocardiographic measurements to perform and describe, at present, the timing of optimal echocardiography performance and reporting should be adequately adapted to the current technical needs and real-life routine clinical practice. Importantly, contextual clinical and (if needed) multimodality assessment should be included in the diagnostic workflow, in order to enable a more individualized approach.
