The juxtaposition of atrial appendage may possibly be diagnosed by angiography recently, and it is widely regarded as an ominous sign of severe cyanotic congenital heart disease. However, it is apparently rare congenital cardiac anomaly in which the atrial appendages lie side by side, both to the left or right of the great arteries, known as left or right juxtaposition of the atrial appendages. Juxtaposition of the atrial appendages has no functional significance, since it does not, itself, cause any hemodynamic disturbance. But it`s presence always indicates the coexistence of other major cardiac anomalies. In review of literatures TGA and VSD are invariable present, and ASD is common. Other anomalies, such as, tricuspid atresia, pulmonary outflow that, obstruction bicuspid pulmonic valve, persistent SVC etc. are relatively high incidence. In this report, we present one case of 6 year old female child having left juxtaposition of atrial appendage combined with TGA [D-looping, D-transposition], TAPVD, large ASD, small VSD, and vertical vein.

From June 1984 to Aug. 1986, 90 cases of open heart surgery were performed at the department of cardiothoracic surgery of Kosin Medical College. There were 63 cases of congenital cardiac anomalies and 27 cases of acquired heart diseases. The sex ratio of congenital and acquired heart diseases were represented as 1.4:1 and 1:1.5 respectively. The age distribution was ranged from 7/12 to 56 years old. Among the 63 congenital cardiac anomalies, 49 cases of acyanotic group and 14 cases of cyanotic group were noted. In 49 cases of acyanotic group, 32 VSD, 15 ASD, 1 PS, and 1 RCA-LV fistula were noticed. In 14 cases of cyanotic group, 7 TOF, 1 TOF (Dextrosardia) combined with IVC interruption, 1 Triology of Fallot, 2 Pentalogy of Fallot. 1 DORV, 1 TA with PDA, VSD, ASD and Left SVC and 1 TAPVC were included. Of the 27 acquired heart diseases, 13 mitral, 3 aortic , 6 bival, 3 triplevalvular diseases and 2 LA myxomas were noted. Overall mortality were 11 cases, which included 2 cases of acyanotic heart diseases, 6 cases of cyanotic heart diseases and 3 cases of acquired hear diseases.

Hypoplastic RV was rarely combined with various other intracardiac anomalies. We experienced the excellent result after surgical correction in these 2 patients. 1. F/7: Combined anomalies were, [1] Hypoplastic Rt. Coronary art.[2] Hypoplastic RV [3] ASD [secundum] & [4] PS [infundibular & valvular] After CP Bypass, [1] Direct suture of ASD [2] Infundibulectomy [3] Pul valvulotomy & [4] Patch enlargement of RVOT with Pericardial monocusp were done 2. F/14: Combined anomalies were, [1] Hypoplastic RV [2] P5 [infundibular] [3] T5 [4] VSD [Type II] [5] ASD [secundum] & [6] 2\ulcornerA-V Block fter CP Bypass, [1] Infundibulectomy [2] Tricuspid valvulotomy [3] Patch repair of VSD & ASD & [4] Implantation of permanent pacemaker were done. Above operations resulted in marked improvement with disappearance of cyanosis & dyspnea.

Seven infants less than age 3 months underwent patch aortoplasty and tube graft bypass for relief of coarctation of aorta. All had intractable congestive heart failure, despite aggressive medical therapy Each infant had other cardiac anomalies including patent ductus arteriosus, ventricular septal defect, atrial septal defect and congenital mitral stenosis. All patients underwent closure of the ductus arteriosus and patch angioplasty of the aorta to produce a luminal diameter of at least 15mm or tube graft interposition utilizing the Gortex tube graft diameter larger than 10mm. In 5 patients who had ventricular defect, they underwent pulmonary arterial banding. &ere was one hospital death 17 days after operation secondary to the hydronephrosis and renal failure. Hospitalization was less than 10 days after operation except one case. In 3 patients who had associated VSD, open heart surgery[VSD closure+PA debanding]was done without difficulty. Surgical repair of critical coarctation of the aorta in infants can safely be offered despite the poor preoperative condition and presence of other cardiac anomalies.

In the case of a vibration sensitive equipment, it require a vibration free environment to provide its proper function. Especially, lithography and inspection device, which have sub-nanometer class high accuracy and resolution, have come to necessity for producing more improved Giga Class semi conductor wafers. This high technology equipments require very strict environmental vibration criteria in proportion to the accuracy of the manufacturing. In this paper, the dynamic analysis and modal test were performed to evaluate the dynamic properties of the constructing clean room structure. Based on these results, a structural dynamic modification(SDM) were required to satisfiy the vibration allowable limit for pression machine. Therefore, in order to improve the dynamic stiffness of clean room structure, the VSD system which can control the force applied on structure, were adopted and its utility were proved from dynamic test results of the improved structure after a modification work.

There have been few reports documenting the outcome of arterial swich operations(ASO) in selected patients with transposition of great arteries(TGA) and with left ventricular outflow tract obstruction(LVOTO). In the case of TGA with LVOTO, if the atrial septal defect(ASD) is large and the ventricular septal defect(VSD) is restricive, this deprives the left ventricle(LV) of approporiate preload and could lead to underdevelopment of the ventircular mass and lead poor LV performance after the arterial switch operation, dspite a high pressure in the LV preoperatively. Because an increase in the systolic ventricular pressure is not necessarily paralleled by an increase in ventricular mass, which is also essential for optimal ventricular performance after the operation. We report here a case of rapid LV training after ASO in TGA with unprepared LV (because of large ASD and restrictive VSD) despite a high pressure in the LV(due to LVOTO) preoperatively.

A patient with intravascular hemolysis due to residual shunt and right ventricular outflow track obstruction after total correction of TOF was presented. The patient was 29 years old female. She underwented VSD closure with dacron patch, infundibulectomy, pulmonic valvotomy and direct closure of PFO. 8 months after the operation, severe intravascular hemolysis and hemolytic anemia appeared. Conservative therapies were not effective, her general condition and laboratory finding got worse gradually. She underwent reoperation, the shunt was closed and right ventricular outflow tract obstruction was corrected by pulmonary valvotomy, infudibulectomy and transannular patch. After operation, hemolysis disappeared dramatically. Severe hemolysis may induce renal failure and necessitate transfusion frequently. If hemolytic anemia is not corrected by conservative treatment, early reoperation is required.

A multistage plan and multidisciplinary approach are the keys to successful repair in patients with pulmonary atresia (PA) with ventricular septal defect (VSD) and major aortopulmonary collateral arteries (MAPCAs). In this article, we present a multidisciplinary approach adopted to treat a patient with PA with VSD and MAPCAs associated with left pulmonary artery interruption.

A male patient weighing 2.5 kg was admitted for respiratory difficulty, and a large ventricular septal defect (VSD) was diagnosed. During care, sudden right leg swelling with a femur shaft fracture occurred. The patient's father had a history of recurrent lower extremity fractures; thus, osteogenesis imperfecta was considered. The patient's respiratory difficulty became aggravated, and VSD repair in the neonatal period was therefore performed with gentle sternal traction and great vessel manipulation under total intravenous anesthesia to prevent malignant hyperthermia. The patient was discharged without notable problems, except minor wound dehiscence. Outpatient genetic testing revealed that the patient had a COL1A1/COL1A2 mutation.
