Figure 4 (A) Apical 4-chamber view (transthoracic echocardiography) showing the tricuspid valve vegetation, right atrium, right ventricle, and inferior vena cava in systole and diastole, with severe tricuspid regurgitation. Ejection fraction was also assessed in this view, using Simpson’s biplane method. (B) Modified 4-chamber view (transthoracic echocardiography) clearly visualizing the tricuspid valve vegetation in systole and diastole, with evidence of right ventricular overload.
