Modern Assessment of Diastolic Function

The goal of this review is to outline the new guidelines released by the ASE/EACVI that seek to simplify the assessment of diastolic function and evaluate the use and potential application of new and emerging technologies. The latest guidelines have decreased the number of parameters needed to evaluate diastolic function to 3. The parameters necessary include peak tricuspid regurgitation (TR) velocity, average E/e′, and indexed left atrial volume (LAVi). At least 2 out of 3 must be positive to determine diastolic dysfunction. There are certain disease states that limit the application of the new guidelines and diastolic stress testing may be indicated in inconclusive cases. New and emerging technologies such as global longitudinal strain (GLS) may provide new opportunities to determine LV filling pressures. New guidelines issued by the ASE and EACVI have simplified the assessment of diastolic function and should be implemented in daily practice.
