A 25-year-old female presented with symptoms resembling those of critical mitral stenosis. Echocardiography revealed a left atrial mass without a stalk, which was suspected to be a left atrial myxoma. An irregular soft friable mass was found at surgery. It measured 10 × 8 cm, with finger-like extensions and occupied almost the entire left atrial cavity, extending into the three tributaries of the right pulmonary vein. Histopathology of the excised tumor including electron microscopy showed a pleomorphic cytology interlaced with bundles, areas of necrosis, and occasional bizarre tumor giant cells. Characteristic histiocytes containing lysosomes identified the tumor as malignant fibrous histiocytoma. A postoperative course of radiotherapy with a dose of 4,000 cGy/20 fractions was applied to the mediastinum. At follow-up 4 months later the patient was asymptomatic. This case is reported because of the extreme rarity of left atrial malignant fibrous histiocytoma.

Primary Cardiac Tumors

Primary cardiac tumors are rare and approximately half of them are atrial myxomas. They rarely remain asymptomatic, especially if large. The imaging of a myxoma by contrast dye during coronary angiography is an infrequent sign, which clarifies the vascular supply of the tumor. We report herein an interesting and rare case of a left atrial myxoma hypervascularized from the right coronary artery.

Cardiac myxomas may have different clinical presentations that may expose the patient to sudden death due to obstruction of the left ventricle inflow. The authors report a case of 34 years old male who was diagnosed with left atrial myxoma that presented as mitral valve obstruction with severe pulmonary hypertension. He underwent emergent sternotomy under cardiopulmonary bypass and the myxoma was successfully removed. The postoperative course was uneventful.

Myxoma is benign tumor of the heart. It is mostly located in the left atrium and revascularized by the left and right coronary artery in 30% to 40% of cases. Symptoms of these neovascularized cardiac myxomas are typically quite variable, from obstruction of mitral valve to coronary embolism resulting in acute myocardial infarction. In this case, left atrial myxoma that is revascularized by nodal branches of the right coronary artery presented as a sick sinus syndrome, which is rare in literature.

Over a period of 18 years, 39 cases of cardiac tumors were operated upon in the Department of Cardiothoracic Surgery at the Postgraduate Institute of Medical Education and Research, Chandigarh. These included 34 (87%) patients with benign tumors and 5 (13%) patients with primary malignant tumors. All the benign tumors were myxomas, of which 31 (91.2%) were in the left atrium and 3 (8.8%) in right atrium. Primary malignant tumors comprised 2 rhabdomyosarcomas, 1 angiosarcoma, 1 lymphoma and 1 case of pleomorphic malignant fibrous histiocytoma. The diagnosis was established by echocardiography, angiocardiography and computed tomography. In one case the diagnosis was made at autopsy. All myxomas, except tricuspid valve myxoma, were removed completely through right atrial or biatrial approach with the use of cardiopulmonary bypass. Four cases of primary malignant tumors were non-resectable. Near total resection of a malignant fibrous histiocytoma arising from the right middle pulmonary vein and left atrial junction was achieved. There were 2 operative deaths (5.1 %). The follow-up ranged from 3 months to 10 years with a mean of 5.7 years. There was 1 recurrence (2.9%) in the benign group. In the malignant group, 3 cases (60%) died within 5 to 8 months of surgery due to further local and metastatic spread of the tumor. The case of malignant fibrous histiocytoma was treated with postoperative radiotherapy to the right mediastinum and is doing well at follow-up 3 months after surgery.

Preoperative Examination

The patient was a 69-year-old male patient with cancer in the right lung and whose preoperative examination showed left atrial myxoma. Simultaneous surgery for both cardiac myxoma resection and a lobectomy by totally endoscopic surgery without robotic assistance was performed. First, the cardiac tumor on the heart was removed using a cardiopulmonary bypass (CPB), then a lobectomy without any new incisions was performed. This case provides evidence that in individual select patients, a left atrial myxoma resection and lobectomy can be performed under total endoscopy at the same time.

Myxomas are benign and the most common tumors of the cardiac muscle (Reynen, 1995). They are predominantly located in the left atrium. Clinical manifestations may vary according to the localization and the size of the myxoma. On the other hand, imaging of a myxoma by contrast dye during coronary angiography is a rare sign, which displays the vascular supply of the tumor. Here, we report the case of a 51-year-old man presenting with presyncope and palpitations due to a giant left atrial myxoma having its vascular supply from the right coronary artery (RCA).
