Mechanism of left atrial enlargement related to ventricular diastolic impairment in hypertension.

abstract：:A space-occupying mass of the right atrium was found by two-dimensional echocardiography and angiography in a 68-year-old woman whose clinical diagnosis indicated multiple pulmonary emboli. Since right heart myxomas frequently cause pulmonary thromboembolism, the patient was initially diagnosed by noninvasive and inva...
