Incidence of heart failure with preserved ejection fraction is increasing and putting the emphases on comprehensive evaluation of diastolic function... Furthermore, diastolic dysfunction even in the absence of heart failure has been shown to have prognostic significance... American Society of Echocardiography and European Association of Echocardiography (ASE/EAE) 2-level decision tree using multi-parametric approach is comprehensive, however discrepancy between the LV filling pressures and LA volume index can lead to discordance and inaccurate assessment of diastolic function... Incremental value of Cardiac Magnetic Resonance (CMR) to Echocardiography in assessment of diastolic function remains unknown... Echo derived LV filling pressures were correlated with Echo and CMR derived LAVI and LAEF... Impact of substituting CMR derived LAVI for ECHO derived LAVI on diastolic function classification was also evaluated. 52 patients underwent CMR and ECHO (32 males, Age 51 ± 18 years, BSA 2.0 ± 0.25 m2)... Mean LVEF and LVMI ( LV mass index) were 58 ± 5% and 95 ± 30 g/m2 respectively... Substituting CMR derived LAVI for Echo derived LAVI improved the concordance between elevated filling pressures and LAVI reclassifying all patients with elevated filling pressures into pseudo normal diastolic function... Compared to echo derived LAVI, CMR derived LAVI had superior correlation to Echo derived LV filling pressures (Fig)... Furthermore LAEF had inverse correlation with LV filling pressures(R = -0.7)... CMR derived LAVI has superior correlation to Echo derived LV filling pressures and can be of incremental value over Echocardiography in assessing diastolic function.
