From January 1980 to December 1989, thirteen patients underwent operation for ventricular septal defect associated with aortic insufficiency in Kyungpook national university hospital. Ten male and three female patients ranged in age from 3 years to 25 years, with an average age of 11.5 years. Aortic cusp prolapse was found in eight cases[61.5%]. The aortic regurgitation was classified by Sellers` method with grade I in 2 cases, grade II in 9 cases, and grade III in 2 cases. Direct suture or patch repair of ventricular septal defect was performed through the right ventricle. Eight cases were treated only by closure of VSD, 3 cases by plication, but two of the letter were reoperated due to the persistent of aortic regurgitation and fungal endocarditis respectively. Aortic valve replacement were performed in 2 cases at the first operation. There was only one late death[7.7%], which was caused by postoperative fungal endocarditis. Follow-up for twelve patients except one death were followed up for 3 months to six years after operation. Residual aortic regurgitation was noted in six cases[46.2%], but the postoperative course of them were uneventful.

Increased clinical interest, stimulated by newer diagnostic techniques, has made it apparent that Ebstein`s anomaly represents a spectrum of right heart abnormalities. In the usual case, the septal and posterior leaflets of the tricuspid valve are not attached to the true annulus, but are displaced distally into the ventricle. Also the degree of malattachment and the structural deformities of the cusps may vary greatly. Recently we experienced 6 cases of Ebstein`s anomaly who underwent corrective operation in our hospital. Five patients were operated by plication and annuloplasty techniques based on the construction of a monocusp valve by the use of the anterior leaflet. Remained one was operated on by tricuspid valve replacement using No 31 mm C-E tissue valve. There was no operative mortality and the postoperative courses were relatively good with marked symptom improvement.

Last year in this department 100 cases of open heart surgery were done annually. This year 200 cases of open heart surgery were scheduled. During the first 6 months of this year 112 open heart surgery cases were done with 13 deaths [11.6%]. There were 72 cases of cougenital malformation with 9 operative deaths [12.5%], consisting of 23 acyanotic cases with one death [4.5%] and 49 cases of cyanotic cases with 8 deaths [16.3%]. Out of 40 tetralogy of Fallot, 6 cases expired [15%]. For 39 cases of acquired valvular heart disease and one Ebstein anomaly valves were replaced with 4 operative deaths [10%]. Single valve replacement in 33 with 3 operative deaths and double valve replacement in 7 cases with one death were noted. Two patients expired among 28 mitral valve replacement cases [7.1%]. Among 7 double valve replacement patients, consisting of 3 mitral and aortic and 4 mitral and tricuspid valve replacement one case expired. In a case of Ebstein anomaly, tricuspid valve was replaced with plication of atrialized right ventricle successfully. The operative result was excellent.

From April 1984 to April 1990, seven patients with Ebstein's anomaly underwent surgical repair. Mean age at operation was 18.6 years (range, 2 to 46 years). Operations were performed using hypothermic cardiopulmonary bypass. Surgical procedures included tricupid valve replacement (n:6) and tricuspid valve reconstruction (n: 1). There were two hospital deaths. There have been no late death. All survivors are in New York Heart Association class I or II with a median follow-up of 6.2 years(range, 4 to 8.3 years).

Isolated congenital left ventricular diverticulum is a rare cardiac malformation. Here, we report the case of a 33-year-old woman who had suffered from recurrent transient ischemic attacks for 6 years. Preoperative cardiac magnetic resonance imaging and computed tomography angiography revealed a diverticulum near the apex. The diverticulum was successfully obliterated by cardiopulmonary bypass. We suggest that isolated congenital left ventricular diverticulum can be easily corrected with a low surgical risk by patch repair and plication techniques.

Congenital diaphragmatic eventration is a rare disease and generally accepted as an abnormally high position of part or all of the diaphragm, usually associated with a marked decrease in muscle fibers and a membranous appearance of the abnormal area. There were 4 cases of the congenital diaphragmatic eventration at the Dept. of Thoracic Surgery, Seoul National University Hospital, from 1957 to 1977. They were two boys and two girls and ranging from 1 day to 3 years of age. They were all repaired by surgical operation and one was expired postoperatively, another one was dead one year later due to complication. The ratio between right and left was 1:3 and their symptoms were cyanosis, dyspnea and frequent respiratory disease. In physical examination there was noted decreased breathing sound on the affected lung field and bowel sound was audible in some cases. Diagnosis was done by Chest X-ray and plication of the affected diaphragm was usually done in operation. There were noted atelectasis and cystic change of the affected side lung. And the liver, colon, spleen and small intestine were found in the dome of the eventrated diaphragm.

Diaphragmatic eventration is a rare disease and is caused by congenital etiology. We operated on a patient who had had preexisting left diaphragmatic eventration which was complicated by a right diaphragmatic paralysis and a persistent respiratory insufficiency due to a traffic accident. This was a very rare case and there has not yet been any case reports worldwide. We were able to abtain good surgical results from plication of left diaphragm in this case and thus report it.

As the load density of KEPCO system is higher, the fault current can be much higher than SCC(Short Circuit Capacity) of circuit breaker. Fault current exceeding the rating of circuit breaker is a very serious problem in high density load area, which can threaten the stability of whole power system. Even though there are several alternatives to reduce fault current, as the superconductivity technology has been developed, the HTS-FCL (High Temperature Superconductivity Fault Current Limiter) can be one of the attractive alternatives to solve the fault current problem. This study presents the application plication of 154kV HTS-FCL in Korean power system.

Acute gastric volvulus is one of the most fatal complications of the eventration of diaphragm and require emergency surgical treatment unless it is possible to pass a nasogatric tube. This 10 year old female patient was admitted because of severe abdominal pain and marked abdominal distention before about 3 days. On chest P-A and plain abdomen, there were the elevation of the left hemidiaphragm and marked dilatation of stomach and the triad of symptoms emphasized by Bochdalek in 1904 was present. Emergency operation [wedge resection of necrotic area of stomach and gastropexy after gastric decompression and plication of diaphragm] was performed. The type of gastric volvulus was organo-axial rotation, in which the stomach rotated around the line that connects the cardia with the pylorus [Fig. 4].

One case of surgically treated sliding esophageal hiatal hernia associated with bleeding gastric ulcer is presented. The patient was 73 years-old woman who had suffered from epigastric heartburn, indigestion, and melena since 3 months prior to admission. Esophageal hiatal hernia was suspected on the simple chest film and the diagnosis was confirmed by tetralogic barium study of the gastrointestinal tract. Hematemesis and melena were persisted so emergent thoracotomy and abdominal exploration were undertaken. Repair of hiatal hernia by constricting suture around relaxed esophageal hiatus was made and plication sutures were Inserted between esophagogastric junction and median arcuate ligament of diaphragm. Concomittently, subtotal gastrectomy with Billroth II procedure was performed to removal of large bleeding ulcer on the lesser curvature of the stomach antrum. Postoperative course was uneventful.
