Figure 1. Transthoracic echocardiography found that the giant aneurysm (yellow arrows) close to right coronary artery opening (A), with thrombus contained and no flow signal inside, compressed the anterior part of tricuspid annular and right ventricle, but the diastolic flow velocity at tricuspid valve orifice and middle part of right ventricular cavity was normal (B).
