A surgical operation on a patient with infected left atrial myxoma is presented. The patient was a 50-year-old woman who was admitted to the Kyung Hee Medical Center Hospital on March 7 1987 with complaints of high fever, cough and dyspnea that occurred a few days prior to admission. She, who no definite history of the previous cardiac-related problems was obtained from, had visited a dentist to have her eight teeth pulled out a few months prior to this admission. A preoperative 2-D echocardiogram revealed a left atrial tumor, strongly suggesting myxoma and two blood cultures drawn prior to surgery yielded streptococcus viridans. Under the preoperative impression of an infected left atrial myxoma, the tumor was removed through a biatrial approach after establishing CPB and cold cardioplegic. Pathologic examination of the tumor demonstrated a typical myxoma with bacterial colonies within. Postoperative course was uneventful and she was completely well at discharge from the hospital. To our best knowledge, this report is the first surgical experience of infected left atrial myxoma in the Korean literature.

Primary cardiac tumor is rare and the most Intracardiac tumor is atrial myxoma which occurs about 75% in left atrium, Biatrial myxomas are very rare Intracardiac tumor which have reported first by Ripstein in 1953 and successful surgical removal by Beeler and Kaufmann in 1961. We have experienced a case of biatrial myxomas intraoperatively which had diagnosed as left atrlal myxoma preoperatively and removed those under moderate hypothermia and cardiopulmonary bypass at the first In Korea, The patient was discharged with .good results, So we want to report this case with the review of the literatures.

Left atrial myxoma, an unusual clinical entity, may cause severe and progressive cardiac disease mimicking mitral valvular disease. In recent years, increased clinical awareness and improved diagnostic techniques has led to a higher incidence of correct preoperative diagnosis. Recently we experienced 2 cases of left atrial myxoma, which were removed successfully under the cardiopulmonary by pass. The first case was 45 years old woman and the second was 23 years old female. Preoperative definite diagnosis was entertained by angiocardiography and echocardiography in both cases. In the first case, tumor was removed with left atriotomy and atrial septectomy was done with additional right atriotomy. In the second case, tumor and atrial septum were removed en bloc through the right atrium. Both patients were discharged with good results 2 weeks postoperatively.

Myxoma of the heart can now be successfully treated but the success is obviously dependent upon the correct diagnosis and treatment prior to development of catastrophic complications such as sudden death, embolism or cardiac failure. The right ventricular myxoma is very rare, and we treated successfully a case of giant right ventricular myxoma, sessile tumor originated from ventricular apex, weighed 175 gm. The tumor base was broad, about 3 cm x 3cm, and it was hardly adhesed to the tricuspid valvular structures, but could remove with the preservation of adequate residual ventricular chamber size and the maintenance of functional tricuspid valve anatomy. The postoperative course was excellent and uneventful.

From July 1966 to July 1983, sixteen atrial myxomas in fifteen patients were seen at Severance Hospital. Fifteen of the sixteen myxomas were located in the left atrium and one in the right atrium. All the cases except three were correctly diagnosed preoperatively. Presently, M-mode and two-dimensional echocardiography are utilized as safe, reliable, and noninvasive imaging modalities. Echocardiography provided an accurate diagnosis in twelve cases since November 1977. In all cases, myxoma were excised successfully. On patient had reoperation and mitral valve replacement on postoperative first day due to persist mitral regurgitation after excision of left atrial myxoma. One patient had recurrence requiring reoperation 37 months after primary operation. Follow up results of each patient were excellent.

Primary neoplasms of the pericardium are rarer than those originating within the myocardium or endocardium and, moreover, primary benign tumors of the pericardium are of much rare occurence. Mahaim[1945] was able to collect 84 cases of pericardial tumors, the majority of which were malignant. A case of primary benign fibromyxoma of the pericardium is presented. This tumor arouse in the right anterior aspect of the pericardium, through which the phrenic nerve was penetrated. The tumor was measured 10X6X6 cm in size and 120 gm in weight. Total excision of the mass was accomplished by antero-lateral thotacotomy incision, resulting complete cure. This is the first case of primary benign fibromyxoma of the pericardium on literatures in our knowledge.

Primar99y cardiac tumors are rare and about 25% of primary cardiac tumors are malignant. A primary undifferentiated cardiac sarcoma, which very rare, is presented as follows: A 28-year old woman at the 32th week of pregnancy was admitted to the hospital because of dyspnea. A large intracardiac (left atrium) tumor was found with cardiac echocardiography and MRI. Emergency operation was performed under the diagnosis of left atrial myxoma. After Cesarean section, LA-tomy was done under the cardiopulmonary bypass. Tumor removal including endocardium of left atrium was done and final pathologic diagnosis was primary undifferentiated laft atrial sarcoma. After adjuvant radiotherapy, she has been followed up in out patient bases without problems up to now.

Congenital polyvalvular disease is a connective tissue disorder affecting more than one heart valve with variable involvement of the entire valvular and subvalvular apparatus. It is frequently associated with the Trisomy 18 and trisomy 13-15 or ventricular septal defect and patent ductus arteriosus. We present an isolated case of congenital polyvalvular disease in a new born baby with a review of the pertinent literatures, which has not been described in Korea. The mass was discovered as a right atrial mass in the prenatal ultrasonography and it was thought to be either a hematoma or a myxoma in the preoperative echocardiography. Microscopic examination of the surgically resected mass showed irregular thickening, nodulation, and additional features of calcification and ossification in the valvular connective tissue on the body of anterior and septal leaflet of tricuspid valve. Congenital polyvalvular disease should be included in the differential diagnosis in cases showing valvular calcification or ossification in the fetal echocardiography.

Primary and metastatic tumors involving the heart are relatively uncommon in dogs. In this study, we provide the echocardiographic diagnosis of intracardiac masses in 2 Yorksire terrier dogs. In the first case, the mass was attached between ascending aorta and pulmonary artery and caused moderate aortic regurgitation and moderate left ventricular dilation. The case was graded into ISACHC II heart failure. The dog was treated with common cardiac medications (i.e. furosemide, enalapril, pimobendan) and oral chemotherapeutic agent (i.e. lomustine). In the second case, the mass was occupied 2/3 of the left atrium and caused marked dilation of left atrium and severe mitral regurgitation (~5 m/s), but not severe congestive heart failure (ISACHC Ib). Although the nature of progression of the mass was likely to cardiac myxoma, the biopsy was not performed due to the owner's refusal. The dog was currently treated with cardiac medications (i.e. ramipril, clopidogrel) and bronchodilator (i.e. aminophylline). Those two dogs are still survived and are currently regularly checked.

Mediastinum is a very rare primary site of liposarcoma. In general, wide surgical excision with adequate resection margin is the treatment of choice for lipesarcoma. We experienced a case of liposarcoma in a 24 year-old male who complained of dyspnea and chest discomfort. Symptoms had been developed a month before admission, and the intensity had been gradually increased. He visited another general hospital, and there he received left closed thoracostomy because hemothorax was suspected. Afterwards, he was transferred to our hospital without a specific diagnosis, on review of outside chest computed tomography film, mass shadow was detected in the mediastinum. For the further evaluation, we checked the chest sonography and chest magnetic resonance imaging. MRI showed 10 cm sized mass contacted with pulmonary artery trunk and left main pulmonary artery. The radiologist strongly suggested sarcoma. On the 4th day after admission, we performed emergent exploratory left thoracotomy for hematoma evacuation because mediastinal shifting progressed and heart rate was increased. Biopsy confirmed that the evacuated materials were extraskeletal myxoid chondresarcoma, so we performed extrapleural left pneumonectomy including diaphragm and a part of the pericardium. The final pathologic diagnosis was myxoid/round cell liposarcoma. He was discharged without complication and systemic chemotherapy was scheduled to begin 2 month later. During chemotherapy, local recurrence and peritoneal metastasis developed, and he died 10 month after the surgical excision. We report this case with reviewal of literature.
