Total anomalous venous return defines a group of congenital heart disease which have in common the entire pulmonary venous drainage returning directly or indirectly to the right atrium instead of to the left atrium. Despite of recent advance in treatment, this severe malformation in its various anatomical forms has a high surgical mortality during early infancy. Because of the high mortality in the untreated infant and the surgical risk in the first year of life, the timing of the operation remains important for optimal result. Three cases of T APV R, two supracardiac types and one mixed type, were treated with extracorporeal circulation during last three years in the Dept. of Thoracic and Cardiovascular Surgery, Seoul National University Hospital. The first one was 10 months old male with supracardiac type which drained through left innominate vein, and he was operated with profound hypothermia and total circulatory arrest but failed. The second case was 7 years old male with supracardiac type drained through left innominate vein, and he was well post operatively, and followed periodically for 12 months. The third case was 24 years old female with mixed type drainage (left upper pulmonary vein drained through left innominate vein, and the others through coronary sinus) was successfully corrected, and she was followed for 4 month without problem. All cases were diagnosed with cardiac catheterization and angiocardiogram, and also with echocardiogram in last two cases. In first two cases of supracardiac type, total circulatory arrest was used in brief period during anastomosis between common pulmonary venous trunk and left atrium. In the last case of mixed type, usual cardiopulmonary bypass with moderate hypothermia was used and total circulatory arrest was not needed.

During the period from March, 1963, to November, 1977, forty-eight patients with secundum type atrial septal defects have undergone surgical repair using cardiopulmonary bypass with a pump oxygenator at the Seoul National University Hospital. Twenty-six [55 percent] of the patients were females and Twenty-two [45 percent] were males. The patients varied in age from 3 years to 51 years. We have divided secundum defects into three types. These are: 1] the high defect; 2] Ovale type defect; and 3] low defect including the defect in the area of the coronary sinus. An ovale type defect was present in forty-one cases [85 percent]. Partial anomalous pulmonary venous connections were present in two patients in the high defect group. All of the forty-eight patients had had right heart catheterization before operation. The pulmonary to systemic flow ratio [Qp/Qs] was determined in our 38 patients. The Qp/Qs was less than 1.5/1 in only five of the 38 patients. Among the 33 patients with moderate and severe left-to-right shunts [Qp/Qs 1.6-3.5/1], the systolic pulmonary artery pressures. ranged from 30 to 80 mm Hg. Large left-to-right shunts [Qp/Qs>3.6/1] were present in 13 patients. The postoperative complications occurred in 13 patients [27. 1 percent]. Postoperative wound infections were the most frequent complications being present in 6 patients [12.5%]. Forty-six of the patients with secundum atrial septal defects survived surgical repair of their defects. Thus the hospital mortality of surgery was 4.2 percent. The causes of death in the early postoperative period were: 1] low cardiac output syndrome related to severe pulmonary hypertension in one case; and 2] postoperative several bleeding in one case.

Myxoma constitue about 50% of a II primary cardiac, tumor (incidence 0.03%) and occur in any of the cardiac chambers, but about 75% of themare found in the left atrium. As is well known, left atrial myxoma usually simulates mitral valvular disease, and it tends to bring about postural syncope and frequent embolic manifestaticns. The clinical manifestation of left atrial myxoma upon the circulation are obstructive effects, embolic effects and constitutional effects. Diagnosis is now most of all important since surgery can be dramatically curable, whereas untreated myxoma apparently invariably lead to deadful course. Preaprative diagncsis by echocardiogram is so simple and accurate for detection of myxoma that awareness of mitral valvular heart disease with rapid deterioration must be screened. We have diagnosed one case of the left atrial myxoma preopratively by phonocardiogram, echocardiogram and levophase pulmonary angiograJ;n and successfully treated by operation under extra corporeal circulation. A 38 years old housewife was admitted to the National Medical Center because of dyspnea, and paroxysmal cough on occasions for prior to hospitalization. Operation was carried out by median sternotomy and left atriotomy with mild hypothermia under E.C.C. The left atrial myxoma was extirpated including endocardial fragment and its weight was 23gm. The hospital course was not eventful and she can work nowadays without symptoms.

Here we present the case of an 11-year-old female patient diagnosed with Caroli syndrome, who had refractory esophageal varices. The patient had a history of recurrent bleeding from esophageal varices, which was treated with endoscopic variceal ligation thrice over a period of 2 years. However, the bleeding was not controlled. When the patient finally visited the Emergency Department, the hemoglobin level was 4.4 g/dL. Transhepatic intrajugular portosystemic shunt was unsuccessful. Subsequently, the patient underwent percutaneous transhepatic variceal obliteration. Twenty hours after this procedure, the patient complained of aphasia, dizziness, headache, and general weakness. Six hours later, the patient became drowsy and unresponsive to painful stimuli. Lipiodol particles used to embolize the coronary and posterior gastric veins might have passed into the systemic arterial circulation, and they were found to be lodged in the brain, kidney, lung, and stomach. There was no abnormality of the portal vein on portal venography, and blood flow to the azygos vein through the paravertebral and hemiazygos systems was found to drain to the systemic circulation on coronary venography. Contrast echocardiography showed no pulmonary arteriovenous fistula. Symptoms improved with conservative management, and the esophageal varices were found to have improved on esophagogastroduodenoscopy.

Clinical study on hemodynamics of healthy elders before and after tread mill. Using doubleblind, placebo-controlled study design. Seventy-five 50-70 years old volunteers without organic disease were divided into two groups, Ginseng group and control group. Each subject was received 3 g Korea Red Ginseng (KRG) capsules or placebo per day for 4 weeks. Before and after administration 4 weeks, the symptoms were asked and hemodynamics parameter such as pump function, systolic function, preload and afterload were recorded before and after tread mill 1,5, 10 minutes by the method of thoracic impedance cardiograph. The result showed that Ginseng could improve quality of life, had obvious effect of increasing PEP (pre-ejection period), PEP/LVET (pre-ejection period/left ventricular ejection period), PCWP (wedged pressure pulmonary capillary). The change rate of HR (heart rate), SV (stroke volume) in KRG group were much lowered, while EF (ejection fraction), LVET (left ventricular ejection period), LVEDP (left ventricular end diastolic pressure) was recovered much quickly. The circulation showed Ginseng could improve the quality of life though its promoting circulation function which are increasing both the systolic function and the preload.

Fibrothorax is the end stage of chronic pathologic processes of pleura such as hemothorax, empyema, or tuberculous effusion. The pleural space become adherent and obliterated, and the lung parenchyma is covered by a thick, fibrous, unexpandable "peel", so the lung function is diminished markedly with impaired ventilation and oxygenation. Constrictive pericarditis is often accompanied fibrothorax, also cardiac and hemodynamic function is deteriorated. Surgical relief of these fibrous peels causes remarkable improvement in pulmonary function, cardiac and hemodynamic function, and subjective symptoms. We experienced a case of bilateral fibrothorax combined with constrictive pericarditis which occured 3 years after bilateral tuberculous effusion. Decortication and percardiectomy were done at the same time through bilateral submammary thoracotomy with sternal transection. Comparing postoperative Peripheral venous pressure, Circulation time, Pulmonary function test, Arterial blood gas analysis, Subjective symptoms with preoperative conditions showed noticeable improvement.provement.

In our hospital we have seen 20 cases of congenital diaphragmatic anomalies from June 1984 until December 1993. These were classified into 10 cases of diaphragmatic eventration, 8 cases of Bochdalek hernia, 1 case of Morgagni hernia, and 1 case of esophageal hiatal hernia. Diaphragmatic eventration cases were composed of 8 males and 2 females with ages varing from 3 hour to 42 year. They were discovered by symptoms: 5 cases of respiratory insufficiency; 3 cases of frequent respiratory infection; and 2 cases by chance; 6 cases involved the left side, 4 cases involved right side. Emergency operations were done to 4 patients. Among the 10 patients, only one operative mortality occurred; 3 hour old female.Bochdalek hernia cases composed 6 females and 2 males, 5 patients were less than 6 hour old. All patients were operated on an emergency status and three of them expired due to the vicious cycle of pulmonary hypertension and pulmonary vasoconstriction, persistent fetal circulation, hypoxia, and metabolic acidosis. Morgagni hernia was seen in one 69 year old female patient, she had no complaint of symptoms and was incidentally detected. Hernia was repaired through right thoracotomy. She was discharged with healthy appearence. Esophageal hiatal hernia was seen in a 10 month old male patient, his symptoms were persistent vomiting and coughing since birth. Sliding type of esophageal hiatal hernia repair was completed through left thoracotomy.

Patients with double-inlet left ventricle usually have a small ascending aorta. In the Norwood procedure, which involves a staged operation, a neoaorta is constructed with a homograft, and the pulmonary artery plays a role in the systemic circulation. Dilatation or aneurysmal changes can occur over time due to the exposure of the neoaorta to systemic pressure, which may induce adverse effects on adj acent structures. We report a rare case of surgical repair for neoaortic root dilataiton with aortic regurgitation, compressing the left pulmohary artery, in a patient who underwent the Norwood procedure.

Extracorporeal circulation leads to functional disorder and structural damage of organs, especially hematologic and pulmonary system, mainly by sequestration of neutrophils and deposition of macrophages at lung. Then, proteases are secreted, which insult vascular basement membrane of pulmonary capillary and alveolar septa of the lung. Among these, the most important protease at lung is elastase, because major component of lung is elastin. For prevention of lung injury, inactivators or antidotes to elastase should be necessary and Alpha 1-Proteinase Inhibitor is the elastase inactivator. Clinical experimental study was carried out to investigate the immediate postoperative change of serum Alpha 1-PI level following cardiopulmonary bypass for 20 heart cases [congenital 16 cases, acquired 4 cases] and 10 control [subtotal gastrectomy] cases. Also preliminary study was performed for 31 cases of open heart patients. The results were as follows: l. Immediate postoperative serum levels of Alpha 1-PI was significantly decreased at open heart surgery group [P< 0.005], but not decreased at control group. 2. There were no significant difference in change of serum Alpha 1-PI level between and membrane and bubble oxygenator group.Z 3. There were no significant difference in changes of serum Alpha 1-PI level between CHD and AHD. Alpha 1-PI is consumed at lung during cardiopulmonary bypass and increase after operation compensatedly and protect multiple organic damage especially lung. Therefore, Alpha 1-PI can be indicator for evaluation of prevention and treatment of pump-lung syndrome.
