Figure 1. – Two-dimensional transthoracic and transesophageal echocardiographic evaluation; A) apical four-chamber view in systole displaying an opened and retracted tricuspid valve, while the mitral valve is closed; B) apical four-chamber view in systole (focused on the right ventricle) displaying an opened and retracted tricuspid valve, while the mitral valve is closed; C) triscupid flow curve, by continuous Doppler, showing a pressure equalization between the right atrium and ventricle.
