The study consisted of all patients over 35yerars old undergoing surgical repair of atrial septal defect for the period from June 1985, to August 1992. The following results were observed. 1. ASD was closed with patch in 11 (73%) patients. 2. The relationship of pulmonary artery systolic pressure to Qp/Qs ratio was not significant. 3. Before operation 6 patients were in NYHA functional class II. 8 were in class III, After operation 8 patients were in class I, 6 were in class II. 4. Atrial fibrillation has persisted in 3 patients and returned regular rhythm in 1 patient after surgery. 5. There was no operative mortality and we had good surgical results regardless of patient's age.

Carcinoembryonic antigen(CEA) was measured in the serum and urine of 46 patients with bladder cancer and 15 patients with non-cancer disease as control group at the Paik Hospital. Pusan during the period from January, 1986 to June, 1988. The following results were obtained. 1. The upper limits of normal serum and urinary CEA levels in non tumor control group were 3.7 ng/ml and 2.3 ng/ml. Mean and positive rate of serum and urinary CEA levels in bladder cancer group were 4.40 ng/ml(37.0%) and 21.52ng/ml(65.2%). 2. Mean urinary CEA level was correlated significantly with the stage, grade and size of bladder cancer but no significance was seen in serum CEA. In the advanced cases(Stage C, D), serum CEA levels were elevated. 3. The diagnostic rate was not elevated in spite of urinary CEA determination combined with urinary cytology. After transurethral resection of cancer mass and radiation therapy, urinary CEA level decreased. As a result, serum and urinary CEA determinations in bladder cancer have no diagnostic value, but it will be useful in the study of the extent of cancer, effect of therapy, recurrence and prognosis.

An experimental study in vitro using piezoelectric extracorporeal shock wave lithotriptor(EDAP LT-01) and urinary stones removed from the patients by surgical method has been performed. The purposes were 1) to correlate the stone components and sizes with the storage of complete fragmentation, 2) to examine the screening effect and 3) to observe the stone fracture mechanism in urinary stones. The following results were obtained. 1. Tribasic calcium phosphate stone, magnesium ammonium phosphate stone and uric acid stone fractured more easily than calcium oxalate stone. In the case of small stones(diameter 0.5 cm), all stones fractured at relatively low storage. Large stones (diameter 1.5 cm) fractured at high storage with wide variations according to components. 2. Magnesium ammonium phosphate stones tested to observe for screening effect showed that a high storage was needed for complete fragmentation(about 2 times) when the stone debris was not removed. 3. Urinary stones fractured first on the front surface. When the stones showed lamellae, which were separated first by shock wave, thereafter each lamella was broken.

PURPOSE: To evaluate CT features of metastatic ureteral tumors. MATERIALS AND METHODS: CT findings in 16 patients with ureteral metastases were evaluated retrospectively ;there were eight cases of bilateral ureteral involvement. Primary tumors metastatic to the ureter were advanced gastric cancer (n=13), breast cancer (n=l), colon cancer (n=l), or adenocarcinoma of unknown primary (n=l). We analysed CT findings with regard to the site of ureteral obstruction, configuration of obstructed sites of ureter, presence or absence of periureteral soft tissue density, and status in other organs. RESULTS: Among 24 ureters involved, ureteral wail thickening was noted in 15, periureteral soft tissue density in 13. Small nodular enhancing lesions less than lcm, within the retroperitoneal space around the involved ureters were noted in seven patients, and four of them were multiple lesions. CONCLUSION: Among various primary tumors, gastric cancer was the most common cause of ureteral metastasis. The common CT findings of ureteral metastases were thickening of ureteral wall, periureteral soft tissue density, and small periureteral enhancing nodular lesions. The constellation of these CT findings may be helpful in making the diagnosis of ureteral metastases.

The long QT syndromes have been classified into acquired or inheritary forms, both of which are associated with a characteristic type of life-threatening polymorphic ventricular tachycardia called torsade de points. Beta-adrenergic blocker is the first cholic treatment, but in those whom cardiac events are not prevented by beta - blockade, left thoracic sympathetic ganglionectomy may be useful in selected cases. A 50-year-old woman had an recurrent syncopal attack in which she was unconscious for 1-2 min and 1-2 times a month for 10 years. The EKG revealed that QT & QTc intervals were 744 and 632 msec respectively. Treatment with Beta-adrenergic blocker and calcium channel blocker was ineffective in preventing recurrence of syncopal spell. Therefore, she underwent left thoracic sympathetic ganglionectomy with thoracoscope. During the 9 months after operation, she was free of syncopal episodes and is doing well.

Isolated congenital aneurysm of the left atrium with intact pericardium is a rate anomaly, which usually presents with arrhythmia, cerebral embolism or abnormalities on routine chest X-ray. Surgery is indicated in most cases to eliminate a potential source of systemic emboli and arrhythmias. A 42-year-old woman having cervical cancer, she was suspected of having a left atrial aneurysm on review of chest X-ray and confirmed by echocardiography and cardiac catheterization. Surgical resection of Left atrial aneurysm was achieved without complication using median sternotomy with cardiopulmonary bypass. The postoperative course was uneventful.

BACKGROUND: Recent trends suggest that minimally invasive cardiac surgery reduces postoperative morbidity and offers a cosmetic benefit. This study was performed to evaluate the CPB time, ACC time, OP time, ICU stay and postoperative hospital stay following a lower partial sternotomy and those of the median sternotomy. MATERIAL AND METHOD: A group of 26 adult patients who underwent cardiac surgery through lower partial sternotomy from August 1997 to July 1999 (A group) were compared to 45 adult patients who underwent cardiac surgery through median sternotomy from January 1996 to July 1997 (B group). The mean ages (46.4+/-14.6 years, A group and 46.8+/-13.2 years, B group) were similar. Operations were performed with central cannula and antegrade/retrograde blood cardioplegia. RESULT: There was no death in each group. No differences were found in CPB time, ACC time, OP time, ICU stay and postoperative hospital stay. Postoperative complications were sternal splitting in a patient in group A and a patient with bleeding that required reoperation and a patient with delayed wound closure in group B. CONCLUSION: The lower partial sternotomy offered a cosmetic benefit, but does not significantly reduced the length of operative time and hospital stay. Minimally invasive cardiac surgery will be applied increasing because of the suggested advantage and choosing a proper operative technique will be helpful.
