Key result
Echocardiography correlates with cardiac MRI for ventricular volumes, with reduced bias below ~50 mL.
Why the study?
The study aimed to compare cardiac volumes measured with echocardiography and cardiac MRI in a mixed cohort of healthy controls and patients with AF.

Does echocardiography correlate with cardiac MRI for determining cardiac volumes in healthy controls and patients with atrial fibrillation?
Echocardiography shows good correlation with cardiac MRI for measuring cardiac volumes in AF patients and controls, particularly for volumes under 49.50 mL where bias is minimized.
Echocardiography may offer a feasible correlate to MRI for LV volumes in AF; leaves open prospective validation before clinical substitution.
AIMS: We aimed to compare cardiac volumes measured with echocardiography (echo) and cardiac magnetic resonance imaging (MRI) in a mixed cohort of healthy controls (controls) and patients with atrial fibrillation (AF). MATERIALS AND METHODS: In total, 123 subjects were included in our study; 99 full datasets were analyzed. All the participants underwent clinical evaluation, EKG, echo, and cardiac MRI acquisition. Participants with full clinical data were grouped into 63 AF patients and 36 controls for calculation of left atrial volume (LA Vol) and 51 AF patients and 30 controls for calculation of left ventricular end-diastolic volume (LV EDV), end-systolic volume (ESV), and LV ejection fraction (LV EF). When comparing the two methods, significant positive correlations of EDV (all subjects: r = 0.55; Controls: r = 0.71; and AF patients: r = 0.51) and ESV (all subjects: r = 0.62; Controls: r = 0.47; and AF patients: r = 0.66) were found, with a negative bias for values determined using echo. For a subgroup of participants with ventricular volumes smaller than 49.50 mL, this bias was missing, thus in this case echocardiography could be used as an alternative for MRI. CONCLUSION: Good correlation and reduced bias were observed for LA Vol and EF determined by echo as compared to cardiac MRI in a mixed cohort of patients with AF and healthy volunteers. For the determination of volume values below 49.50 mL, an excellent correlation was observed between values obtained using echo and MRI, with comparatively reduced bias for the volumes determined by echo. Therefore, in certain cases, echocardiography could be used as a less expensive, less time-consuming, and contraindication free alternative to MRI for cardiac volume determination.

Manolé et al. (2021) conducted an observational in Atrial fibrillation (n=123). Echocardiography vs. Cardiac magnetic resonance imaging (MRI) was evaluated on Correlation of cardiac volumes between echocardiography and cardiac MRI (r = 0.55 (EDV), r = 0.62 (ESV), p=< 0.0001). Echocardiography demonstrated significant positive correlations with cardiac MRI for measuring end-diastolic (r=0.55) and end-systolic (r=0.62) volumes, with reduced bias for volumes below 49.50 mL.
