#tt3662. Extreme left atrial dilatation (atriomegaly) in 83 y.o patient with permanent atrial fibrillation, chronic coronary artery disease, arterial hypertension,  and previous surgical mitral valvuloplasty. NYHA class II.
Left ventricular (LV) biplane end-diastolic volume index= 60 ml/m2; LV ejection fraction= 62 %; moderate mitral regurgitation with no significant restriction to LV inflow (mean diastolic transmitral gradient= 6 mmHg).

End-systolic (maximum) left atrial volume: 4-chamber= 1866 ml; 2-chamber= 1137 ml; biplane (modified Simpson’s rule)= 1426 ml (801 ml/m2).
