A 41-year-old woman was admitted to the emergency room with an onset of acute dyspnea, jugular ingurgitation, and with the first heart sound diminished, followed by a grade III/IV holosystolic murmur that was better heard at the apex and edema of the lower limbs.
The vital signs were heart rate 91 bpm, respiratory rate 21 rpm, blood pressure 110/60 mmHg, and oxygen saturation 91%. The chest x-ray showed cardiomegaly with a cardiothoracic index of 0.62 and pulmonary venocapillary hypertension.

Figure 1
Transthoracic 2D Doppler echocardiography in the parasternal long axis view showing a cyst-like thin-walled atrium (A) and moderate mitral regurgitation (B). In the apical chamber a left pleural effusion (C) and also a moderate mitral regurgitation (D) were visualized. Transoesophageal 2D images at 60º and 90º (E-F) confirmed the presence of a heterogeneous cyst-like mass (white arrows) in the left atrium involving the posterior mitral annulus. The color Doppler revealed a blood flow to this cavity (G). LV: left ventricle; LA: left atrium; RA: right atrium; RV: right ventricle; Ao: aorta; PE: pleural effusion.
