[Cardiac tumors: clinical and echocardiographic diagnosis of 65 cases].
65 cases of cardiac tumors were diagnosed and studied by echocardiography. Among them 49 were primary tumors including 43 cases of myxoma, one case each of hamartoma, lipomatous infiltration, fibroma, hemangioma, rhabdomyosarcoma, pericardial mesothelioma, and 16 cases of secondary cardiac tumors. It was found that the nature of primary cardiac tumors could be speculated by two-dimensional echocardiography based on their pathological features. Most patients with large left atrial myxoma had obstructive symptoms of mitral valves, abnormal ECG and enlarged left atrium, whereas patients with small atrial myxoma, embolic phenomenon was liable to occur. Echocardiography of secondary cardiac tumors showed that the tumors usually invaded most frequently both the myocardium and pericardium as single or multiple nodular echoes in the myocardium under pericardium or within the pericardial cavity, with profuse pericardial effusion. Occasionally, the secondary tumor appeared as a large mobile intracavitary mass or an extracardiac one compressing the heart or large vessels. It was noticed that cardiac symptoms might be the clinical clue in certain patients with extracardiac primary malignancy.
