case_images: Fig1
case_images: T waves in V2-4 leads (Fig. 1). Transthoracic echocardiography showed akinesis of the left ventricular anteroseptal-apical wall.
case_images: Left coronary angiography. a Initial left coronary angiography of cranial view revealing embolic obstruction straddling the bifurcation in the left anterior descending artery and diagonal branch (arrow). b Left coronary angiography after aspiration showing the restoration of blood flow

case_images: Fig2
case_images: CAG revealed emboli straddling the bifurcation between the left anterior descending artery and diagonal artery (Fig. 2a). Aspiration was performed with a Thrombuster II catheter (KANEKA Medix Corporation, Osaka, Japan) retrieving a substantial amount of organized material, after which Thrombolysis in Myocardial Infarction (TIMI) grade 3 flow was achieved (Fig. 2b).
case_images: Histopathological findings. a Retrieved embolus. b, c Hematoxylin and eosin staining revealed atypical urothelial cell proliferation

case_images: Fig3
case_images: Histopathological analysis revealed that the emboli originated from an UTUC (Fig. 3a-c).
case_images: Contrast-enhanced computed tomography showed that tumor invading the left renal vein (arrow)

case_images: Fig4
case_images: Contrast-enhanced CT showed tumor invasion to the left renal vein (Fig. 4) and no lung metastasis.
case_images: Transesophageal echocardiography showing a patent foramen ovale and shunt flow (arrow). LA: left atrium, RA: right atrium

case_images: PMC7487790_01_40959_2020_73_Fig5_HTML.jpg
case_images: Fig5
case_images: To examine the intracardiac shunt, we performed transesophageal echocardiography, which confirmed a patent foramen ovale (PFO) (Fig. 5).
case_images: Transthoracic echocardiography on readmission showing right ventricular dilatation and a mobile mass attached to the tricuspid valve (arrow). RV: right ventricle, LV: left ventricle, RA: right atrium
case_images: 40959_2020_73_Fig6_HTML.jpg
case_images: PMC7487790_01_40959_2020_73_Fig6_HTML.jpg
case_images: Fig6
case_images: Transthoracic echocardiography showed right ventricular dilatation and a mobile mass attached to the tricuspid valve (Fig. 6), which suggested that the dyspnea was caused by a pulmonary artery embolism.
