Cardiac myxomas are benign tumors of endocardial origin. Symptoms might mimic heart disease as well as infectious disease, immunodeficiency, and malignant processes. We present the case of a 59-year-old female patient with a large right ventricular myxoma that was connected to the basal interventricular septum. Movement in systole provoked the obstruction of the right ventricular outflow tract. She presented clinically with syncope, systolic murmur, and signs of right heart failure. The diagnosis of the right ventricular tumor was based on 2D echocardiography, magnetic resonance, and multislice computed tomography findings. Emergency surgical excision of the myxoma was necessary to prevent embolism and sudden death.
