Transthoracic echocardiogram. (a1) Long parasternal axis showing pericardial effusion (arrow); (a2) one week later showing resolution of pericardial effusion; (b1) four-chamber view showing marked right atrial dilatation; (b2) four-chamber view one week later showing normalization of right atrial size; (c1) color doppler showing moderate tricuspid regurgitation; (c2) color doppler one week later showing a decrease in tricuspid regurgitation.

Computerized axial tomography was performed, which ruled out pulmonary thromboembolism; a transthoracic echocardiogram showed left ventricular systolic function in the lower normal limit (ejection fraction 51%), moderate dilation of right-sided chambers with decreased systolic function, and moderate tricuspid regurgitation (Figure 1). A new transthoracic echocardiogram evidenced biventricular systolic function within normal parameters with moderate tricuspid regurgitation (Figure 1).
