A 44-year-old patient was admitted with dyspnea and palpitation. Echocardiography revealed a very large (20 cm) mass in the left atrium. Emergency open-heart surgery was done. The most frequent primary heart tumor is myxoma. Their size varies greatly, and not much is known about how quickly they grow. The present case is unusual because of the size of the tumor (20 cm).
