A fifteen-year-old boy was transported to our hospital emmergency room due to sudden onset of chest pain, hemoptysis and dyspnea. He was diagnosed as persistent ductus arteriosus that had developed acute bacterial endocarditis with pulmonic valve vegetation and pulmonary embolism with pulmonary infarction. After conservative antibiotic therapy (vancomycin + aminoglycoside), we operated this patient successfully - patch closer of the ductus and pulmonary valve valvuloplasty - under the cardiopulmonary bypass.

Twenty six patients were operated a total correction of tetralogy of Fallot between Jan., 1984 and July, 1985 at the Dept. of thoracic and cardiovascular surgery, Chonnam University Medical School, and a comparison between the survived group [n = 18] and the dead group [n = B was performed to detect factors influencing laboratory data, cineangiographic findings, operative findings and methods, and pump time. Following results were obtained, 1. There was no significant difference between two groups in the preoperative P.O2 and hematocrit level. 2. The size of the interventricular defect was not related to the operative mortality. 3. There was a significant difference in mortality rate between combined type of stenosis of pulmonary artery, valve and infundibulum and other types of right ventricular outflow tract stenosis. 4. There was a significant difference in mortality rate between the transannular patch reconstruction and other types of operative procedure. 5. There was no significant difference between two groups in total bypass time and aortic time. 6. There was no significant difference between two groups in left ventricular end diastolic volume and right ventricular end diastolic volume. 7. The operative mortality was related to the ratio of the diameter of the pulmonary valve annulus or each pulmonary artery to the ascending or descending aorta in cineangiographic findings, but there was no statistical significance of which probably is due to the lack of the total number of patients.

Twenty-three patients underwent operations to repair a congenital heart disease through right anterolateral thoracotomy(RALT) between December 1989 and December 1996. Defects repaired 22 atrial septum(13 ostium secundum;3 lower sepal defect;4 posterior septal defect; 1 sinus venosus;1 ostium primum) and 1 ventricular septal defect. There was no operative mortality or late morbidity directly related to RALT. The RALT incision is a safe and effective me hod to a median sternotomy in selective patients(especicially female). The cosmetic results are very good during the follow up periods.

This series compromised 31 patients with pulmonary hypertension of 282 patients of ventricular septal defect(VSD) who underwent operation at the department of Thoracic and Cardiovascular Surgery in Chonnam University Hospital, from January, 1986 to December, 1991. Pulmonary hypertension was noted in 59 of 280 cases of VSD. Of them, 31 cases underwent cardiac catheterization on postoperative 8th to 77th month. Age at operation was ranged from 10 months to 29 years (mean 9.13 years). 17 patients were male and 14 patients were female. Results of follow-up studies were as follows: Cardiothoracic ratio was decreased from 0.59${\pm}$0.04 to 0.54${\pm}$0.03 (p=NS). Postoperative systolic pulmonary arterial pressure (PAPs), mean pulmonary arterial pressure (PAPm), and systolic right ventricular pressure (RVPs) were decreased significantly (p<0.001). And also Rp/Rs was decreased from 0.37${\pm}$0.21 to 0.14${\pm}$0.06 (p<0.02). However, systemic arterial pressure (SAP), right atrial pressure (RAP), and pulmonary capillary wedge pressure (PCWP) were changed insignificantly. There were significant relations of follow-up period with the decrement of PAP(p<0.005). In contrary, ther were no relations between the decrement of PAP and the age at operation. These data suggested that the long-term hemodynamic changes remained to be determined in some of the patients, even though they Were asymptomatic, with pulmonary hypertension.

This report is a review of 98 cases of the primary mediastinal tumors which are treated in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital from January, 1985 to February, 1993 and divided two groups. One group is from January, 1985 to January, 1989 and named it Group 1[G1]. Another group is from February, 1989 to February, 1993 and named it Group 2[G2]. Chest pain is the most common clinical manifestation in the two groups. The common mediastinal tumors are teratoma 11 cases[29.7%], neurogenic tumor 7 cases[18.9%], thymoma 6 cases[16.2%], primary cyst 3 cases[8.1%] in Group 1 and thymoma 16 cases[26.2%], teratoma 15 cases[24.6%], neurogenic tumor 9 cases[14.8%], primary cyst 9 cases[14.8%] in Group 2. Therefore this result shows that the incidence of thymoma is increased in group 2. In benign tumors, the subjective symptoms are 64.3% in group 1 and 63.6% in group 2. In malignant tumors, they are 100% in group 1 and 82.4% in group 2. this result shows that asymptomatic malignant tumors are increased in group 2. The successful excision is done in all of the 71 benign tumors except one. In malignant tumors, the complete surgical excision is increased from 11.1% in group 1 to 41.2% in group 2.

The clinical and pathological analysis of solitary pulmonary nodules were estimated in 35 patients with nodules who were surgically resected at the Dept. of Thoracic and Cardiovascular Surgery of Chonnam National University Hospital from July 1978 to Aug. 1989. The results were as follows: 1. Mean age of patients was 43.5 years extending from 11 years to fi7 years old and male to female ratio was 6: l. 2. Preoperative symptoms were complained of dull pain in the chest, cough, hemoptysis and general weakness in 69% of patients. 3. The histopathologic findings of surgically resected nodules showed benign nodule in 51% and malignancy 49%. The most frequent diseases were granuloma[67%] in benign nodules and squamous cell carcinoma[76%] in malignancy. In topographical region of nodules in the lung, benign granuloma was more prevalent in upper lobes, while malignancy was slightly more frequent in lower lobes. 4. The incidence of malignancy by age was extremely rare in patients with less than 35 years old, but in greater than 35 years of age, malignancy comprised up to 67% of patients. 5. Complications of thoracotomy were minor bleedings, wound infections and chest pain not to be required any reoperation except one patient died of sudden onset of arrhythmia after pneumonectomy.

Ruptured aneurysms of the sinus of Valsalva are relatively rare, and the incidence seems to be higher in oriental than in western countries. Eight patients underwent operative treatment at Chonnam University Hospital from June, 1986 to May, 1992. Six of the patients were male and two female. Age ranged from eight to fifty six years. Associated cardiac lesions were common including AR and VSD in four patients respectively. Diagnosis was made by 2D-Echo and cine-angiogram. In six patients aneurysms of the sinus of valsalva ruptured from the right coronary sinus to the right ventricle and in two from right coronary sinus to the right atrium Direct closure of aneurysmal rupture and patch closure of VSD in four cases, resection of the aneurysm and direct closure in one case, direct closure of the fistula and AVR in two cases, direct closure in one case were performed. One patient combined with VSD, pulmonary hypertention and bacterial endocarditis underwent operation, but he died of sudden cardiac arrest the day after the operation. Operative results were relatively good in the other patients.

Ten patients with tetralogy of Fallot were studied angiocardiographically before a modified Blalock-Taussig shunt and again 25*3.2 months after the previous shunt. All of ten patients had patent previous shunt at the time of follow up examination. Pre-and postoperative diameters of left and right pulmonary artery and descending aorta were measured and pulmonary artery index [the sum of the crossectional areas of the right and left pulmonary arteries standardized by the body surface area] was calculated. The ratio of mean diameter of left and right pulmonary arteries to the diameter of the descending aorta [LPA+RPA/2xDA] was increased postoperatively by 0.20*0.068 [p=0.020]. Mean PAI [pulmonary artery index] increased from 283.8*178.4 mm/m2 BSA to 345.8~144.5 mm/m2 BSA after shunt operation [p=0.019]. This results suggested that the modified Blalock-Taussig shunt was effective to help growth of the pulmonary arteries in most cases of the study populations but the ones with the PAI>233mm*/m* BSA appeared less benefited by Blalock Taussig shunt. Calculation of PAI could be an aid to making a decision whether to perform a one stage corrective surgical procedure or a palliative shunt procedure in the patient with small pulmonary arteries.

A 34-year-old man was admitted to the hospital because of ascites, abdominal fullness. computed tomography and cavography revealed inferior vena cavil occlusion just above the hepatic vein and diagnosed as Budd-Chiari syndrome. conservative medical therapy failed to control the symptoms produced from both portal hypertension and versa caval stasis. Therefore, under extracorporeal circulation with moderate hypothermia and normal cardiac contraction, membranoto y and inferior vena casa venoplasty with Gore-tex (10mm) was performed. Postoperatively, physical examination revealed oral ulceration, subcutaneous thrombophlebitis, folliculitic lesions. uveitis And increased reactivity of the skin to needle punctures. 10 month later, superior vena ciiva obstruction symptom was found. Hehcet's disease was diagnosed.
