The clinic symptoms of cardiac occupying lesions are complex and difficult to diagnose currently. In this study, three cases of atrial angiosarcoma, left ventricular aneurysm and left ventricular diverticulum were selected, respectively. The clinical characteristics, imaging features (echocardiogram, cardiac CT and MRI) and the postoperative and pathological results for patients were studied. We compared the differences in clinical symptoms, morphology, histology and haemodynamics among the three patients. The diagnosis were confirmed by intraoperative and postoperative pathological examination. We conclude that proper imaging approaches would be beneficial to diagnose the cardiac occupying lesions. Accurate preoperative diagnosis is beneficial to preoperative preparation as well as the decrease in operative risks.
