A, Transthoracic echocardiogram showed a giant left atrium (96mm*135mm*98mm). B, The post-operative TTE showed the left atrium with an anteroposterior diameter of 4 cm.

Transthoracic echocardiogram showed a severe mitral stenosis (estimated mitral orifice size, 0.58 cm2) and moderate regurgitation, severe tricuspid regurgitation and a giant left atrium (96mm*135mm*98mm) with thrombi (Fig. 1A). The follow-up of the echo demonstrated the remarkably decreased left atrium with an anteroposterior diameter of 4 cm and well mechanical mitral valve function (Fig. 1B).
A, Axial computed tomography (CT) revealed a giant left atrium and calcification of the wall. B, Frontal chest radiograph of the patient with giant left atrium. The cardiothoracic ratio was almost 0.9.

A computed tomography scan showed that the LA measured 20.0cm * 13.7 cm (coronal plane) with massive calcification and compressed the left ventricle, right ventricle and right atrium (Fig. 2 A&B).
A, The post-operative CT scan of the chest showed a marked decrease of left atrium. B, Post-operative frontal chest radiograph of the patient showed a marked reduction in the cardiothoracic ratio.

The patient recovered very well and a post-operative chest CT scan showed a marked reduction in the cardiothoracic ratio (Fig. 3 A&B).
