A. Transthoracic echocardiography: the thrombus straddling a PFO extending into the RA and LA; the red arrow is pointing at the thrombus in the RA and LA. B. Transesophageal echocardiography: the red arrow is pointing at the thrombus stuck in a PFO. C. Transesophageal echocardiography: the red arrow is pointing at the thrombus stuck in a PFO moving into ventricle in diastole. D. Electrocardiogram on admission: SR 79/min, ST-segment elevation in precordial V1–V4 leads and pathological Q wave in precordial V1–V3 leads. E. Coronary angiography: massive thrombotic burden in the middle-distal part of the LAD (the red arrow is pointing at the part of the massive thrombus). F. Computed tomography image: a massive thrombus in the pulmonary artery; the red arrow is pointing at the thrombus in the LPA and RPA. G. Computed tomography image: the thrombus in the LA; the red arrow is pointing at the thrombus in the LA. H. Computed tomography image: the thrombus in the RA; the red arrow is pointing at the thrombus in the RA. Abbreviations: PFO, patent foramen ovale; LA, left atrium; RA, right atrium; LV, left ventricle; RV, right ventricle; SR, sinus rhythm; LAD, left anterior descending artery; LPA, left pulmonary artery; RPA, right pulmonary artery
