난원와 하부에 위치하는 하정 맥동형 심방중격결손증(inferior sinus venclsus defect)은 매우 드문 선천성심질환으로 수술 전 이차공형 심방중격결손증과 감별이 어렵고 수술 중에도 발견하기가 쉽지 않다. 저자들은 10세 때에 심방중격결손증으로 단순 봉합술 시행 후 별 문제없이 지내다가 이비인후과 수술 위한 사전 검사로 시행한 심장초음파 검사상 잔여 심방중격결손증이 발견된 24세 여자 환자에서 심방중격결손증 재수술을 시행하였다. 환자는 이차공형 심방중격결손증과 하정맥동형 심방중격결손증을 동시에 가지고 있었으나 일차수술에서 하정맥동형 심방중격결손증을 발견하지 못하여 이차공형 심방중격결손증만 교정된 상태였고, 금번 재수술에서 하정맥동형 심방중격결손증을 확인하고 패취 봉합을 시행하였다.

Seventy cases of open heart surgery were performed in the department of Thoracic and Cardiovascular Surgery, Pusan Paik Hospital, Inje College, from Oct. 1985 to Oct. 1986. And the results were summarized as follows. 1. Among the 70 cases, there were 48 cases of congenital heart anomalies and 22 cases of acquired rheumatic valvular heart diseases. Age range of the congenital patients was 7 months to 31 years with the mean age of 10 years, and the acquired patients was 18 to 62 years with the mean age of 40 years. 2. The heart-lung machine used for cardiopulmonary bypass was Sarns 7000, 5-head roller pump, and the number and type of oxygenators were 5 of membrane type and 65 of bubble type. For all cases GIK [glucose-insulin-potassium] solution was used as cardioplegic solution for myocardial protection during operation. 3. Among the 48 congenital anomalies, there were 12 cases of ASD group, 29 of VSD group, 3 of ECD, 3 of TOF and one of PDA + MR, and to all of which the appropriate radical operations were applied. 4. Among the 22 acquired valvular diseases, there were 11 cases of mitral valve diseases [MS; 4, MSr; 3, MRs; 4], 3 cases of aortic valve diseases [AR:1, ARs;1, ASr;1], 4 cases of double valve diseases [MRs+TR; 3, MRs+ARs; 1] and 4 cases of triple valve diseases [MSr+ASr+TR; 3, MSr+Ar+TR; 1]. To all the diseased mitral and aortic valves, artificial valve replacement was applied except one [As], in which valve plication was applied. And to all the diseased tricuspid valve, DeVega annuloplasty was applied. 5. The number of replaced artificial valves were 29 in 25 patients [congenital; 3, acquire; 22]. In MVR, 6 of mechanical valves [St. Jude Medical valve; 6] and 15 of tissue valves [Carpentier-Edward valve; 11, lonescu-Shiley valve; 4] were used. In AVR, 6 of mechanical valves [St. Jude Medical valve; 6] and 2 of tissue valves [Carpentier-Edward valve; 2] were used. 6. Postoperative complications were occurred in 12 cases. Among them 11 cases were recovered with intensive cares, but one patient [VSD + Fistula of Valsalva sinus] was expired with low cardiac out put syndrome.

We prospectively studied postoperative cardiac arrhythmia after open heart surgery to analyze the types and incidence of cardiac arrhythmia and to predict preoperative risk factors. And also we evaluated the effectiveness of atrial and ventricular epicardial electrodes which were placed during operation Between March 1990 and August 1990, We had operated on in 211 patients and we studied 201 consecutive patients excluding 10 patients. The study group included 99 males and 102 female patients, ages 1 month to 75 years[Mean$\pm$SD=28.0$\pm$21.7 years]. Postoperatively, all patients were regularly seen by the cardiac surgeon and cardiologist, They had continuous electrocardiographic monitoring for the first 3 days, initially in the intensive care unit and were checked routine electrocardiography on the postoperative 7 days, The postoperative cardiac arrhythmia were analyzed and possible associations of this arrhythmia with various pre, intra, and postoperative factors were studied by univariate and multivariate discriminant analysis, The overall incidence of postoperative cardiac arrhythmia except relative sinus bradycardia was 36.8%;[74/201], The incidence of postoperative cardiac arrhythmia in acyanotic congenital heart disease: 19.4%, cyanotic congenital heart disease: 20.8%, cardiac arrhythmia surgery: 33.3%, acquired valvular heart disease: 60.9% and coronary artery occlusive disease: 38.9%. Both univariate and multivariate studies indicated the pre operative symptom duration[p = 0013], the duration of medication[p=0.003], presence of preoperative arrhythmia[p<0.001] and pre-operative left atrial dimension in echocardiography to be the factor promoting postoperative cardiac arrhythmia. Multivariate discriminant analysis showed that the presence of preoperative cardiac arrhythmia, bypass time and the duration of preoperative symptom duration conveyed considerable risk factor on post-operative arrhythmia. The atrial wire electrodes were used diagnostically in 36 and were used therapeutically in 89 among 201 patients. Atrial pacing were used to treat relative sinus bradycardia, accelerated junctional tachycardia or premature atrial or ventricular contractions in 51 patients. Atrioventricular sequential pacing were used in 16 patients and ventricular pacing were used in 20 patients. Hemodynamics were evaluated in 2 patients of relative sinus bradycardia before and after atrial pacing. The atrial pacing increased the amount of cardiac output to 15% more. Because of their great utility in the diagnosis and treatment of arrhythmias, we conclude that routine placement of atrial and ventricular electrodes at the time of operation is indicated regardless of the nature of the open-heart procedure.

From Oct. 1983 to Dec. 1991, 135 cases of atrial septal defect which were operated at the department of Thoracic and Cardiovascualr Surgery, Chonnam National University Hospital, were analysed retrospectively. They were 23.7% of all congenital heart diseases operated in the same period. Among the 135 cases, 62 cases were male and 73 cases were female. Their ages were ranged from 2 to 54 years and the mean was 18 years old. Main symptoms at admission were exertional dyspnea[70.37%], frequent URI[49.12%] and palpitation[32.59%], but 12 cases[8.88%] were asymptomatic. Electrocardiographic findings wer regular sinus rhythm in 96.99%, RVH in 64.66%, incomplete RBBB in 27.06%, complete RBBB in 42.10%, and first degree AV block in 9.02% All 135 cases were operated under the direct vision with cardiopulmonary bypass. Anatomically, most frequent type was fossa ovalis defect with complete septal rim[78.52%]. 117 of 135 ASD patients were repaired with pathch closure[86.66%] and 14 patients were repaired with direct closure[10.37%] and 4 patients in mutiple ASD were repaired with patch and direct closure[2.96%]. Postoperative complications were occured in 21 cases[15.56%], and they were wound infection, pleural effusion, postoperative bleeding, urinary tract infection, and heart failure mainly. One case died due to epidural hematoma and operative mortality was 0.74%.

The congenital long QT syndrome (LQTS) is an inherited cardiac disorder characterized by increased QT intervals and a tendency to experience ventricular tachycardia, which can cause fainting, heart failure, or sudden death. A 4-year-old female patient undergoing velopharyngeal correction surgery under general anesthesia suddenly developed Torsades de pointes. Although the patient spontaneously resolved to sinus rhythm without treatment, subsequent QT prolongation persisted. Here, we report a case of concealed LQTS with a literature review.

Cor triatriatum is a rare congenital malformation of the heart, in which a septum stretches in a transverse or oblique plane through the left atrium, thus separating it into two compartments. The upper one connects with the pulmonary veins, and the lower one connects with the left ventricle. Due to the rarity of, and great difficulty in-diagnosing, cor trlatrlatum, data On the surgery of this disease are of necessity very limited and so accurate pre-operative diagnosis was very difficult to make. `We experienced a case of the cyanotic congenital heart disease which was diagnosed as a large atrlal septal defect with streaming venous blood from inferior vena cava to left atrium through atrial septal defect in August, 1982. We found that there were transverse septum in the left atrium through atrlal septal defect, the pulmonary venous drainage were located in the upper chamber of the left atrium, and the lower chamber was connected with the left atrial appendage, mitral valve and `left ventricle. But our case had not any opening in this transverse septum and the right atrium was connected with the upper chamber of the left atrium through the upper part of the atrlal septal defect, and was communicated with the lower chamber of the left atrium through the lower part of the atrlal septal defect. We excised the transverse septum and repair this atrial septal defect with Woven Dacron patch accompanying with the drainage of coronary sinus to right atrium. The post-operative course was not eventful and he was discharged with good result on the post-operative 8th day, and has been in good .condition up to now for longer than 10 months.

The principal aim of surgery for congenital heart anomalies is the establishment of normal hemodynamic function. Palliative and corrective operations are selected with time to attain this end with minimal risk. In recent years, as operative mortality after primary total correction is lower than the mortality after early palliation and delayed correction, corrective operations in infants have increasingly supplanted palliative ones. Two hundred and eighteen infants below 10 kg with congenital heart anomalies underwent primary surgical intervention at Yonsei Medical Center from March 1979 to June 1985. There were 155 infants with VSD, 35 Infants with TOF, 5 infants with ECD, 4 infants with TGV, 3 infants with DORV, 3 infants with Pulmonary atresia, 3 infants with ASD and PDA, 2 infants with DOLV, and the remainders were Sinus Valsalva rupture, residual mitral regurgitation after total correction of ECD, PAPVR, Cor triatriatum, Truncus arteriosus, and Tricuspid atresia. The overall surgical mortality was 15.1%. In the acyanotic group, 13 infants died among 168 infants, and mortality was 7.7%. But in the cyanotic group, the mortality rate was very high and 20 infants died among 50 infants raising the mortality to 40.0%. These poor surgical results in the cyanotic or complicated group was due to inaccurate diagnosis, improper surgical methods and inadequate post-operative care which should be improved.

Implantable cardioverter defibrillator (ICD) can be a crucial therapeutic modality for pediatric patients with congenital heart disease, Brugada syndrome, long QT syndrome and cardiomyopathy. Because transvenous implantation of ICD is mostly unfeasible for pediatric patients due to anatomical and technical limitations, epicardial patch type or subcutaneous type ICD have been used. Implantation of these alternative ICDs, however, was reported to be frequently associated with significant complications. We report a case of successful intrapericardial implantation of a single coil-type ICD through the transverse sinus in a 27 month-old child weighing lesser than 10 kg, and it was inferred from this experience that this alternative technique may decrease complications and morbidities after ICD implantation in children.

Background: Atrial fibrillation (AF) is a common complication in elderly patients with atrial septal defect (ASD). The purpose of this study was to examine the efficacy of the maze procedure in these patients. Materials and Methods: Between February 2000 and May 2011, 46 patients underwent the maze procedure as a concomitant operation with ASD closure. Three patients who underwent a right-sided maze were excluded, and one patient was lost to follow-up. The mean follow-up duration was $3.2{\pm}2.5$ years. Electrocardiography was performed 1 month, 3 months, 6 months, and 1 year after surgery, and checked annually after that. Results: AF persisted in 4 patients after surgery. One year after surgery, among 38 patients, 55.3% remained in sinus rhythm without antiarrhythmic drugs. However, when including the patients who took antiarrhythmic drugs, 92.1% were in sinus rhythm. Freedom from AF recurrence at 3 months, 6 months, 1 year, 2 years, 3 years, and 5 years after surgery were $97.4{\pm}2.6$, $94.4{\pm}3.8$, $91.2{\pm}4.9$, $87.8{\pm}5.8$, $79.5{\pm}7.6$, and $68.2{\pm}12.4$, respectively. There was no early mortality after operation. Conclusion: Concomitant treatment with the maze procedure and ASD closure is safe and effective for restoring the sinus rhythm.
