(tt3662) Extreme left atrial dilatation (atriomegaly) in 83 year old patient with permanent atrial fibrillation, chronic coronary artery disease, arterial hypertension,  and previous surgical mitral valvuloplasty (residual moderate regurgitation). 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).

#tt3662.患有永久性房颤、慢性冠状动脉疾病、动脉高血压和既往二尖瓣成形术史的83岁患者，发生极端左房扩张（心房肥大）。NYHA II级。
左室（LV）双平面舒张末期容积指数= 60ml /m2；左室射血分数= 62%；中度二尖瓣返流，对左室流入血流没有明显限制(经二尖瓣舒张期平均压差= 6 mmHg)。
收缩期末(最大)左房容积：4腔= 1866 ml；2腔= 1137ml；双平面(修正辛普森规则)= 1426 ml (801 ml/m2)。
