From 1970 to 1986, 3 males and 6 females, ranging in age from 13 to 69 years (median 45 years), underwent heart surgery for a primary cardiac tumor. Six patients had a left atrial myxoma; a lipofibroma, a lymphosarcoma and a rhabdomyosarcoma were found each in 1 patient. The following complaints were present: congestive heart failure in 8, fatigue in 7, cardiac arrhythmia in 3, palpitations in 3, fever in 2 and finally weight loss, nocturnal perspiration and clubbing were each in one patient. The duration of symptoms ranged from 6 weeks to more than 2 years (median 10.8 months). All patients were operated with the aid of extracorporeal circulation as soon as they were diagnosed. One patient with extensive tumor growth died at the end of the procedure. During the follow-up period all patients with a primary malignant tumor died within 3 months. Those with myxoma or fibroma are still alive with a follow-up period extending to 13 years (median 7 years). All surviving patients are asymptomatic and well. Malignant cardiac tumors do have a very poor prognosis, they are only amenable for palliative resection and even then prognosis remains poor. When an endocardial biopsy confirms the diagnosis of a cardiac malignancy, the indication for operation is questionable, although there is an absolute indication in case of obstruction. Cardiac myxoma should be resected after diagnosis because the potential embolic complications may be debilitating or lethal. The operative risk is small, and the long term results are excellent.

Cardiac myxoma is a benign neoplasm composed of stellate to plump, cytologically bland mesenchymal cells set in a myxoid stroma. Although benign, as they can lead to severe complications, they are often removed surgically. A 39-year-old female presented with a chief complaint of generalized fatigue. Patient had a history of a large 7cm x 2.5cm left atrial myxoma resected at the age of 32 years after she presented with symptoms of dyspnea on exertion. The dyspnea was due to prolapse of the mass through the mitral valve during diastole, leading to functional severe mitral stenosis. The mass was resected with clear margins confirmed on biopsy. On physical examination, heart rate was regular with no murmurs. No signs of congestive heart failure were noted. A 2D echo revealed a mobile structure in the left atrium along with mild mitral regurgitation. Cardiac MRI showed a 21mm x 9mm well defined, pedunculated, mobile mass in the left atrium arising from inter-atrial septum. The mass was hyperintense on T2 weighted images with patchy delayed hyper-enhancement consistent with recurrence of a myxoma. The patient underwent a repeat median sternotomy with the removal of left atrial mass and repair of atrial septum with hemashield patch. The mass was sent for pathological evaluation confirming the diagnosis of recurrent myxoma. On genetic testing, patient tested negative for mutations in PRKAR1A gene (mutated in up to 60%-80% cases with Carney complex), MEN1, RET and sarcoma (TP53) genes. Cardiac myxomas are rare primary benign tumors of the heart with a small recurrence rate. Follow-up studies have rarely reported recurrences after complete resection. However, in our case not only did the patient have the sporadic form of myxoma with recurrence, but it also occurred within three years of the previous resection despite complete removal with clear margins.
