Key result
CMR parameters including LA maximal volume over 52 mL/m2 reliably identify LV diastolic dysfunction.
Why the study?
Although cardiac magnetic resonance has been increasingly used to evaluate LV diastolic function, the most frequently used parameters, their diagnostic thresholds, and their correlation to echocardiographic and invasive measurements required systematic description.
Which cardiac magnetic resonance parameters and thresholds are most reliable for assessing left ventricular diastolic function?
Systematic Review (n=102)
Which cardiac magnetic resonance parameters and thresholds are most reliable for assessing left ventricular diastolic function?
Specific CMR parameters, including LV untwisting, early filling rates, and LA emptying fractions, are promising and reliable measures for diagnosing LV diastolic dysfunction.

CMR parameters enable reliable noninvasive LVDD assessment in practice; extends echocardiography-based diagnostics with validated thresholds.
Bojer et al. (2021) conducted a systematic review in Left ventricular diastolic dysfunction (n=102). Cardiac magnetic resonance (CMR) was evaluated on CMR parameters and thresholds for LV diastolic dysfunction. Cardiac magnetic resonance measures such as early peak filling rate <2.1 s-1 and LA maximal volume >52 mL/m2 are reliable indicators of left ventricular diastolic dysfunction.
