Background: TNF-$\alpha$ plays a major role in producing left ventricular dysfunction cardio-myopathy pulmonary edema and inhibits the compensatory mechanism of congestive heart failure. IL-6 is an acute reactant of immune reaction and also known to control immune reaction but its function in the myocyte was not clearly investigated. Author's performed this experiment to investigate the contents of TNF-$\alpha$ and IL-6 on the assumption that TNF-$\alpha$ and IL-6 may reside in nonfailing heart that has gone cardiac surgery and play some role in cardiac function. Material and Method : Right auricular tissues were sampled from 12 patients who had undergone total corrective surgery for both congenital and acquired heart diseases from January 1998 to June 1998 in Kosin Universcfy Gospel hospital. The quantitive analysis of TNF-$\alpha$ and IL-6 were assessed by ELISA method in right auricular tissue. Hemodynamic values about the pressure of ventricle atrium aorta pulmonary artery and cardiac index pulmonary and systemic vascular resistance and cardiac output were measured by echocardiography and cardiac catheterization and biochemical analyses of LDH & AST were done before operation. statistical analysis was by Paired Student t-test. Patients were divided into children(under 15 years olds) and adults groups and the data was compared beween two groups. Conclusion: Mild pulmonary hypertension and increased pulmonary vascular resistance were existed in both group. The contents of tissue TNF-$\alpha$ IL-6 in each group were independent of each data.

Background: Tumors of the heart are uncommon. The aim of this study is to review our clinical experience and outcome of surgical treatment of cardiac neoplasm. Material and Method: From March 1990 to December 2005, 35 patients(14 males and 21 females) with mean age of 52.4 years underwent surgical treatment of cardiac neoplasm. The clinical and pathologic data were analyzed retrospectively. Surgical treatment consisted in complete resection of the tumor in all cases but 1 patient who was left ventricular fibroma received biopsy only. Result: Thirty cases were benign and five cases were malignant tumor. Benign tumors were myxoma(29 cases) and fibroma(1 case). Five malignant tumors were osteosarcoma, hepatocellular carcinoma, renal cell cancer, yolk sac tumor, and unclassified myxoid spindle cell type sarcoma. There were no operative mortality in benign cases and twenty seven cases of myxoma were followed up for 8 months to 15 years without recurrence. But four patients of malignant tumor were expired within six months after operation. Conclusion: Left atrial myxomas are most common benign neoplasm. Surgical treatment is effective for the benign cardiac tumors but prognosis is poor in patients with malignant cardiac tumors.

Cardiac fibroma is a rare benign tumor of the heart that occurs primarily in infants and children. Prognosis depends on size, extent and site of tumor. Cardiac fibroma may invade the conduction system, papillary muscle and outflw of inflow tract of ventricle. In these situations, its clinical course is very poor Although operative mortality is high, surgical resection is treatment of choice because lethal arrhythmia and sudden death can be developed by the fibroma. A cardiac fibroma was successfully resected from the left ventricular myocardium of a 8 years old male patient in the Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital.

Materials and methods: Between 1979 and 1996, 27 patients with primary cardiac tumor underwent surgery at Catholic University Medical College. Mean age of patient was 45.1${\pm}$3.03 ranging from 21 to 67 years old. Twenty-four cases were myxomas, 2 cases were chondrosarcoma, and remained case was angiosarcoma. Diagnosis was confirmed by echocardiography, cardiac angiography, CT scan, and MRI. The most common site of tumor origin was fossa ovalis limbus area(17cases:63%). A biatrial operative approach was commonly used in 15 cases and the tumor was removed through left atriotomy site. Complete excision of the tumor with a cuff of normal tissue was performed. All heart chambers were carefully explored for evidence of multicentric myxomas or other tumor debris. Most of the patients were improved on postoperative period compared to preoperative NYHA functional class. Results: There was one operative death due to low cardiac output syndrome. Follow up period was 3 months to 17 years. There was 2 late deaths due to local recurrences. Conclusion: complete surgical excion is important for increasing cure rate. Malignancy cannot be ruled out even though preoperative echocardiography suggests benign nature. Chest CT or MRI is effective for further evalution in addition to echocardiography. In suspicious of malignancy, more extensive resection is essential and postoperative chemotheraphy or radiotherapy is useful.

Primary cardiac tumors are rare, and primary malignant cardiac tumors are even rarer. Of these, angiosarcoma was uncommon, Surgical resection of the tumor was very difficult because symptoms were nonspecific and did not become present until the tumor had advanced. A 15-year-old male patient was diagnosed with primary cardiac angiosarcoma by microscopic examination under surgery and underwent resection of the tumor, which compressed and obstructed the right atrium. He was discharged from the hospital after 15 days without any problems.

Because of paucity of primary cardiac tumors, primary cardiac tumors are of much interest to the pathologist, cardiologist and cardiac surgeon. A cardiac chondrosarcoma, which very rare, is presented as follows: This 37 year-old female patient was admitted under the diagnosis of a left atrial tumor(myxoma) on July 3, 1993. Using the CPB, she underwent complete removal of tumor including the atrial septum. And final pathology report was chondrosarcoma. The adjuvant irradiation with total dose of 5040 cGy(28 fractiations for 2 months) and chemotherapy(VP-16 and ifosfamide) was completed. She had no evidence of recurrence until May 2, 1995. when she was admitted due to brain metastasis, which was detected by MRI scan with a tumor free interval for 2 years. A tumor, located around the frontoparital cortex was removed neurosurgern on Sep. 13, 1995 and the final pathology report was also a chondrosarcoma on pathologic exam. The postoperative course was uneventful.

We report a case of primary cardiac fibroma which is a rare cardiac neoplasm and arising most frequently from right ventricular free wall and interventricular septum. A 2-month-old male infant with cyanosis was admitted for evaluation and treatment. Echocar-diographic lEnding was a cardiac mass. Successful nearly total removal of the tumor was performed. The pathologic result was compatible with fibroma. The postoperative course was not eventful, and have been in good condition upto now.

A fibroma arising in the right ventricle outflow tract of a 14 month-old infant was successfully removed. The patient was first seen because of shortness of breath and tachycardia. Pertinent clinical and laboratory findings included a grade II/VI systolic murmur, blood pressure of 120/60 mmHg, slight cardiomegaly on chest X-ray, a mass obstructing the outflow tract of the right ventricle on echocardiography and magnetic resonance imaging. On october 30,1992, under cardiopulmonary bypass, a 4cm x 3cm x 3cm tumor was resected from the right ventricular outflow tract, together with a portion of the ventricular wall. Histologically, it was diagnosis as a fibroma. The patient was sent home on the 6th postoperative day following an uneventful recovery form the operation. Although cardiac fibroma is the second most common cardiac tumor in infancy and childhood, it is usually found in the left ventricle and one arising in the right ventricle is considered rare. Although it is a benign tumor, it could produce a severe cardiac dysfunction and even sudden death, depending on its size and location. With the advance in diagnostic techniques and operative management, there is a renewed interest in the early detection and operative removal of these tumors. The case herein presented is the first such case successfully managed and reported in the Korean literature.

Neuroblastoma is the most common extracranial solid tumor in children, and accompanies various clinical symptoms including hypertension. Hypertension is associated with catecholamines secreted from the tumor, and is usually not severe. We report one case of malignant hypertension with cardiac failure in a patient with adrenal neuroblastoma, successfully treated with adrenalectomy. A 3 year-old boy complained of protrusion of the chest wall. Physical examination revealed severe hypertension with cardiac failure. The levels of metabolites of catecholamine were increased in blood (norepinephrine >2000 pg/mL) and urine (norepinephrine 1350.5 ug/day). Abdominal CT showed a 7 cm-sized solid mass arising from the right adrenal gland. After stabilizing the hemodynamics with oral phenoxybenzamine, right adrenalectomy was performed. Pathological diagnosis was a ganglioneuroblastoma. The hypertension and cardiac failure were resolved after tumor removal.

Primary tumors of the heart are extremely rare, and about 25 per cent of primary cardiac tumors are malignant. Recently, We experienced a case of primary cardiac liposarcoma occurred on the right ventricular outflow tract and extended into the main pulmonary artery. The patient was 57 year-old man and the chief complaints was severe exertional dyspnea. Emergency operation to relieve the right ventricular outflow tract obstruction was performed under cardiopulmonary bypass. The tumor was 5$\times$4$\times$3 cm in size and infiltrated into the right ventricle and ventricular septum. The tumor in the main pulmonary artery was removed without any difficulty but the on the right ventricular outflow tract was difficult to remove completely. The patient was recovered without any specific problems. After successful surgical resection and postoperative radiotherapy the patient discharged with good condition. Herein, the clinical characteristics of cardiac liposarcoma, the problems in differential diagnosis, the prognosis and current therapy are reviewed.
