          Abstract

          Introduction

          In patients with ST elevation myocardial infarction (STEMI), minimizing the reperfusion time is the goal of therapy worldwide. However, the differential diagnosis is critical and when a patient is encountered with chest pain and ST elevation, STEMI should not be the only diagnosis considered. By detailed history and focused physical examination, it is possible to avoid a mistaken diagnosis.

          Case presentation

          In this report, we present a case of a male patient with tongue cancer and accompanying myocardial metastasis that causes electrocardiographic changes, who was initially misdiagnosed with ST elevation myocardial infarction.

          Conclusion

          Here, we reported a case of metastatic cancer in the heart which was initially diagnosed as acute myocardial infarction. Echocardiography, computed tomography and magnetic resonance imaging of the heart were used accordingly to confirm the myocardial metastasis.

          The echocardiographic evaluation of intracardiac masses: a review.

          Echocardiography is an invaluable procedure for the evaluation of intracardiac masses, and can reliably identify mass location, attachment, shape, size, and mobility, while defining the presence and extent of any consequent hemodynamic derangement. With careful attention to mass location and morphology, and appropriate application of clinical information, echocardiography can usually distinguish between the 3 principal intracardiac masses: tumor, thrombus, and vegetation. Transesophageal imaging frequently adds additional important information to the assessment of mass lesions and should always be considered when image quality is inadequate or pertinent clinical questions remain unanswered with surface imaging. This review will focus on primary and metastatic tumors of the heart.

            Growth of hepatocellular carcinoma into the right atrium. Report of five cases.

            Five patients had hepatocellular carcinoma growing into the right atrium. Clinically, all patients had edema in the legs, venous dilatation in the abdominal wall, ascites, and dyspnea. Paroxysmal aggravation of dyspnea and its alleviation by a left decubitus position were noted in three patients. Three patients developed shock after a change in posture. A gallop rhythm in the cardiac murmur was detected in two. Pathologically, all livers had hepatocellular carcinoma and macronodular cirrhosis. At autopsy, a tumor thrombus was found that completely occluded the right hepatic vein and extended into the inferior vena cava and right atrium, partially occluding the inferior vena cava. Antemortem diagnosis of right atrial tumor thrombi in patients with primary hepatocellular carcinoma is difficult, but the condition should be suspected when dyspnea, abnormal cardiac sounds, and shock develop.

              Intracavitary metastatic hepatocellular carcinoma of the right ventricle.

              We report a rare case of direct intracavitary metastasis of a hepatocellular carcinoma (HCC) to the right ventricle (RV) without intravascular involvement. A 65-year-old female, with a history of HCC and partial right hepatectomy, developed symptoms of congestive heart failure. Echocardiography revealed a large tumor in the RV with extension to the outflow tract. Palliative excision of the cardiac tumor under cardiopulmonary bypass and cardioplegic arrest was performed due to severe hemodynamic compromise. The final pathology report disclosed metastatic HCC. Tumor recurrence in the RV was noted 2 months later and the patient succumbed to the disease.
