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.

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.

Congenital atresia of the left main coronary artery (LMCA) is an extremely rare coronary anomaly that necessitates surgical correction. Patients with LMCA atresia may have various clinical symptoms, which are determined by the degree of collateral vessel development from the right coronary system, the metabolic demands of the heart, and concomitant mitral insufficiency caused by myocardial ischemia. Unlike in adults, there are limited surgical options for coronary artery disease in children. Herein, we report a case of LMCA atresia with mitral regurgitation in a 19-month-old child that was successfully corrected by coronary artery bypass grafting and mitral valve repair.

침습성 폐 아스페르길루스증은 주로 면역저하 환자에서 발생하는 것으로 알려져 있지만 드물게 면역저하가 없는 환자에서도 발생한다. 면역저하가 없는 환자에서 발병하는 경우, 초기에 진균에 의한 폐 감염을 의심하기가 어렵기 때문에 진단 및 치료가 늦어지고 나쁜 예후를 보일 수 있다. 저자들은 면역저하가 없는 29세 남성 환자에서 선천성 심장질환 수술 후 발생한 침습성 폐 아스페르길루스증의 사례가 있어 시간 경과에 따른 CT 소견과 함께 보고하고자 한다.

소아의 심장질환을 진단하는데 필수적인 진단도구로 자리를 잡아가고 있는 심초유파 검사는 신속한 확진과 그 방법의 비침습성으로 인하여, 소아 심장 클리닉에 심장질환 검사에 대한 의뢰가 증가되고 있는 실정이다. 그러나 심장질환이 의심되어 소아 심장 클리닉에 진단을 위하여 의뢰된 환아들에 대한 자료의 분석이 거의 없는 상태이므로, 심장질환의 진단을 위해 의뢰된 환아들의 특생에 대한 기초자료로 활용하고자 이들에 대한 자료를 비교 분석하였다. 대상 및 방법으로는 1998년 10월 1일부터 1999년 7월 10일까지 심장 질환이 의심되어 소아 심장 클리닉에 심장 검사를 위하여 의뢰되어 심초음파 검사를 시행한 428명을 대상으로 하였다. 이들 환아들의 자세한 병력, 흉부 방사선 검사, 심전도 검사의 결과와 필요한 경우에 추가 시행한 운동 부하 심전도, 24시간 심전도 및 심혈관조영술의 결과를 병력지를 이용한 후향적 조사룰 하였다. 의뢰 당시 환아의 성별 및 연령별 분포는 남아가 261례(61.0%), 여아가 167례(39.0%)로 남녀 비는 1.6:1이였으며, 1세 미만이 268례로 의뢰된 전체 환아 중 62.6%를 차지하였다. 의뢰된 이유로는 심잡음이 248례(57.9%)로 가장 많았으며 그 다음이 발열이 52례(12.1%), 심전도 이상이 43례(10.0%), 청색층이 33례(7.7%) 등의 순이었다. 의뢰 당시 의심된 심장질환 중 선천성 심장질환이 의심되어 의뢰된 경우는 302례(70.6%)였으며, 후천성 심장질환이 의심된 경우는 76례(17.8%), 부정맥이 의심되어 의뢰된 경우는 50례(11.6%) 로 나타나, 선천성 심장질환이 의심되어 의뢰된 경우가 가장 많았다. 의뢰 당시 의심되는 심장 질환별 임상적 양상 비교에서 선천성 심장질환이 의심된 경우는 심잡음이 248례(57.9%)로 가장 많았으며, 후천성 심장 질환이 의심된 경우는 발열이 52례(12.1%), 부정맥으로 의뢰된 경우는 심전도 검사의 이상 소견이 43례(10.0%)로 가장 많았다. 최종 진단 결과 선천성 심장병이 212례로 49,5%이었으며, 후천성 심장병이 59례로 13.9% 이었고, 부정맥이 13례로 3.0%를 차지하였고, 정상인 경우도 144례로 33.6%나 되었다. 결론적으로 신생아기에는 선천성 심장질환이 많았고, 유아기 이후에는 후천성 심장질환과 부정맥이 증가하는 추세를 보였다. 그러나 심초음파검사를 위해 의뢰된 환아 중 144례 (33.6%)가 심초음파검사에서 정상 소견을 나타내었으므로, 심음 청진에 대한 확신보다는 심초음파검사에 대한 의존도가 지나치게 높은 것으로 나타났다. 따라서, 선천성 심장질환의 감별을 위한 올바른 심음 청진에 대한 훈련이 다시 한번 강조되어야 할 것으로 사료된다.

Background: Early extubation after cardiovascular surgery has some clinical advantages, including reduced hospitalization costs. Herein, we review the results of ultra-fast-track (UFT) extubation, which refers to extubation performed on the operating table just after the operation, or within 1-2 hours after surgery, in patients with congenital cardiac disease. Methods: We performed UFT extubation in patients (n=72) with a relatively simple congenital cardiac defect or who underwent a simple operation starting in September 2016. To evaluate the feasibility and effectiveness of our recently introduced UFT extubation strategy, we retrospectively reviewed 195 patients who underwent similar operations for similar diseases from September 2015 to September 2017, including the 1-year periods immediately before and after the introduction of the UFT extubation protocol. Propensity scores were used to assess the effects of UFT extubation on length of stay (LOS) in the intensive care unit (ICU), hospital LOS, and medical costs. Results: After propensity-score matching using logistic regression analysis, 47 patients were matched in each group. The mean ICU LOS ($16.3{\pm}28.6$ [UFT] vs. $28.0{\pm}16.8$ [non-UFT] hours, p=0.018) was significantly shorter in the UFT group. The total medical costs ($182.6{\pm}3.5$ [UFT] vs. $187.1{\pm}55.6$ [non-UFT] ${\times}100,000$ Korean won [KRW], p=0.639) and hospital stay expenses ($48.3{\pm}13.6$ [UFT] vs. $54.8{\pm}29.0$ [non-UFT] ${\times}100,000KRW$, p=0.164) did not significantly differ between the groups. Conclusion: UFT extubation decreased the ICU LOS and mechanical ventilation time, but was not associated with postoperative hospital LOS or medical expenses in patients with simple congenital cardiac disease.

Between March 1978 and August 1985, 29 cases at various congenital heart diseases were reoperated because of remnant shunt of residual anomalies at Seoul National University Hospital. They were consisted of 10 cases of Tetralogy, 4 simple VSD, 6 complicated VSD. 3 partial ECD, and 5 other rare congenital anomalies. The interval between the initial and the second procedure ranged from 1 day to 122 months [mean; 26.9 months]. In 4 cases of them, the second procedure was done during initial hospitalization within 3 weeks post-operatively. The primary operation intended to be corrective surgery except four whose primary operation was palliative or exploratory one even though it was done with extracorporeal circulation. The indication for second operation was mainly residual shunt or valvular obstruction due to patch detachment or inadequate relief of stenotic lesion. Others were paravalvular leak, valvuloplasty failure, prosthetic valve failure, and inadequate primary diagnosis. Four patients were dead [14.3%]; three complicated VSD`s and one Tetralogy. There were 7 cases of nonfatal complication with subsequent improvement except one [diffuse cerebral dysfunction].

Background: Superior vena cava (SVC) stenosis during follow-up is a major concern after heart transplantation, and many technical modifications have been introduced. We analyzed the surgical results of the SVC intima layer-only suture technique in heart transplantation. Methods: We performed SVC anastomosis with sutures placed only in the intima during heart transplantation. We measured the area of the SVC at 3 different points (above the anastomosis, at the anastomosis, and below the anastomosis) in an axial view by freely drawing regions of interest, and then evaluated the degree of stenosis. Patients who underwent cardiac computed tomography (CT) at 2 years postoperatively between June 2017 and May 2020 were included in this study. Results: We performed heart transplantation in 41 patients. Among them, 24 patients (16 males and 8 females) underwent follow-up cardiac CT at 2 years postoperatively. The mean age at operation was 49.4±4.9 years. The diagnoses at time of operation were dilated cardiomyopathy (n=12), ischemic heart disease (n=8), valvular heart disease (n=2), hypertrophic cardiomyopathy (n=1), and congenital heart disease (n=1). No cases of postoperative bleeding requiring intervention occurred. The mean CT follow-up duration was 1.9±0.7 years. At follow-up, the mean areas at the 3 key points were 2.7±0.8 cm², 2.7±0.8 cm², and 2.7±1.0 cm² (p=0.996). There were no SVC stenosis-related symptoms during follow-up. Conclusion: The suture technique using only the SVC intimal layer is a safe and effective method for use in heart transplantation.

This paper reports 15 native valve endocarditis cases had surgical operation in the past 10 years at the department of Cardiovascular and Thoracic Surgery, Chonbuk National University Hospital. In this study, 10 cases out of 15 were in class I or II by the New York Heart Association functional classification. None of the cases had a history of taking addictive drugs. Five cases were congenital heart disease, three cases were rheumatic heart disease and two cases were degenerative heart disease. Thus 10 cases had the underlying disease. All cases had antibiotics treatment for 3 to 6 weeks before operation. In the culture test, only four cases were positive in the blood culture and one case was positive in the excised valve culture. Organisms on blood and valve culture were Streptococcus epidermis, Streptococcus viridans, Staphylococcus aureus and Staphylococcus epidermidis. In the 10 cases without ventricular septal defect, the aortic valve was involved in four, mitral in four, both in two and involved valves in the 5 cases with ventricular septal defect were tricuspid in three, pulmonic in two. Eight cases had operation because they showed moderate congestive heart failure due to valvular insufficiency and vegetation with or without embolism. Seven cases had operation because they showed persistent or progressive congestive heart failure and/or uncontrolled infection. Five cases with ventricular septal defect underwent the closure of ventricular septal defect, vegetectomy and leaflet excision of the affected valves without valve replacement. In the cases without ventricular septal defect, the affected valves were replaced with St. Jude mechanical prosthesis. Postoperative complications were recurrent endocarditis in two, embolism in one, allergic vasculitis in two, spleen rupture in one and postpericardiotomy syndrome in one. At the first postoperative day, one case died of cerebral embolism. At the 11th postoperative month, one case died of recurrent endocarditis and paravalvular leakage in spite of a couple of aortic valve replacement. In the survived cases[13 cases in this study , all cases but one became class I or II by the New York Heart Association functional classification.
