Twelve patients underwent surgical correction of total anomalous pulmonary venous connection[TAPVC] between Sep. 1989 and May 1993. There were 9 boys and 3 girls whose ages ranged from 10 days to 17 month [median 1.2 month]. Six patients were less than 1 month of age at operation. The anomalous drainage was supracardiac in 6, cardiac in 2, infracardiac in 2, and mixed in 2. There were 3 early death, and its mortality rate was 25%. There were no operative mortality after Sep. 1991. Age at operation, presence of preoperative pulmonary venous obstruction, preoperative assisted ventilation and type of anomaly did not affect early mortality. Late pulmonary venous obstruction was developed in 4 patients between 1 month to 4 month after operation. Among these patients, 2 were died and one was reoperated and well, and the other one was not operated because of patient`s refusal. We conclude that late pulmonary venous obstruction is fatal and its early detection and correction is important for improving late survival.

Partial anomalous pulmonary drainage is frequently accompanied by an atrial septal defect. The anomaly is entirely compatible with life and the clinical findings are dependent primarily on the proportion of the pulmonary venous return to the right atrium. The anomaly is frequently missed even with complete diagnostic study. In this report we are presenting a case of anomalous pulmonary venous drainage combined with atrial septal defect and dextrocardia and the treatment of this condition.

Cor triatriatum is a variant of abnormal connection between the pulmonary vein and true left atrium, which is separated from accessory left atrium receiving pulmonary venous blood flow by fibromuscular diaphragm. Usually it is diagnosed after operation because difficulty in visualization of the diaphragm by conventional diagnostic tools. We experienced a rare entity of congenital heart disease diagnosed as car triatriatum with atrial septal defect and partial anomalous pulmonary venous return after completing operation, which was diagnosed as ASD with PAPVR preoperatively. Anomalous right pulmonary venous opening was located at right atrium, secundum type defect of atrial septum was present, and dual chambered left atrium without connection was also seen. Excision of the diaphragm and wide patch repair of ASD including right pulmonary vein were performed with good postoperative results. Herewith, we report this case with review of literatures.

폐부종은 심인성, 혹은 비심인성 요인에 의해 발생한다. 심인성폐부종(Cardiogenic Pulmonary Edema, CPE)은 심질환, 좌심방 압력의 증가, 폐정맥과 폐모세혈관의 압력 증가와 관련있다. 이와는 대조적으로 비심인성 폐부종(Noncardiogenic Pulmonary Edema, NCPE)은 좌심방의 압력증가에 의해서 혹은 기저질환인 심장 질환과 관련없이 발생한 국소적인 정수압의 증가하여 발생하거나, 폐포나 모세혈관내 피표면의 투과도의 변화에 의해서 발생한다. 혹은 국소적인 정수압 및 투과도의 복합적인 변화 모두에 의하여 발생한다. NCPE의 환축을 적절하게 치료하기 위하여 CPE와 반드시 감별되어야 한다. 또한, 심인성 및 NCPE의 감별 및 적절한 처치를 위하여는 철저한 환축의 병력, 신체검사, 흉부방사선 촬영 등의 검사를 실시하여야 한다. NCPE는 원발요인과 치료반응에 따라 예후가 달라질 수 있다.

Sinus venosus type atrial septal defect is commonly associated with partial anomalous pulmonary venous return[PAPVR . Ideal surgical repair of sinus venosus ASD with PAPVR demands complete closure of septal defect with redirection of the anomalous pulmonary venous return to the left atrium without obstructing the superior vena cava[SVC or the anomalous pulmonary vein and without injury of sinoatrial node and residual shunt. In our two patients, the closure of sinus venosus ASD and correction of PAPVR could be accomplished by simple direct sutures without using a patch or flap. Both patients had a good outcome.

Partial anomalous pulmonary venous connection is frequently found in any ASD(atrial septal defect) patients. These patients are usually symptomatic, therefore, easily diagnosed as just simple ASD. We experienced a case of a 37-year-old female patient with ASD in which the left upper pulmonary vein was connected to SVC by the left inominate vein. The patient was diagnosed as simple ASD previously. During cardiac catheterization, we found a meaningful oxygen saturation step up between the SVC and its upper portion. Angiogram confirmed PAPVC. The surgical correction of anastomosis of PAPVC with left atrial appendage and direct closure of ASD were done. The patient was discharged 15 days later.

Total anomalous pulmonary venous return (TAPVR) is very rare congenital heart disease. 25-year old male was admitted our hospital with dyspnea, headache and syncope as chief complaint. He was confirmed as mixed type TAPVR by echocardiography and cardiac catheterization. In this case, mixed type TAPVR was consisted with supracardiac type connection of left pulmonary vein and cardiac type of right pulmonary vein. Supracardiac type of left pulmonary common channel was anastomosed to the left auricular appendage during total cardiopulmonary bypass with fibrillating heart. Cardiac type of right pulmonary vein was operated during moderate hypothermia and aortic cross clamping. Coronary sinus septum was incised into ASD and closed with Gore-Tex patch so that right pulmonary blood flow directed to the left atrium. The patient's post-operative course was uneventful.

This is case report of total anomalous pulmonary venous return with atrial septal defect which were corrected surgically by intracardiac procedure under total cardiopulmonary bypass.Two patients were supracardiac type,cardiac and mixed type was each one.The mixed type was three years old female patient.She was diagnosed as atrial septal defect with partial anomalous pulmonary venous return[right pulmonary vein drains into superior vena cava and right atrium] and corrected as usual.After operation,she underwent exertional dyspnea and frequent tachycardia.Chest x-ray film showed pulmonary congestion.Follow up cardiac cineangiogram revealed that left pulmonary vein also anomalously drained into left innominate vein through vertical vein.Through left thoracotomy,anastomosis was successfully carried between left atrium and vertical vein without cardiopulmonary bypass and there was no sign of pulmonary artery obstruction for two years follow up.The other three patient were corrected successfully without complication and got good result.

TAPVC represents 1 to 4% of all congenital cardiac defects. Generally severe and refractory cardiac failure develops in the majority of patients in the early infancy. In a small minority of patient, they are relatively asymptomatic in infancy, but symptoms will develop of necessity In the later life. Our three cases had dyspnea on exertion and cyanosis and had a history of frequent respiratory infections. All 3 cases had the typical showman configuration on roentgenograms of the chest. Current surgical therapy has greatly altered the unfavorable course of these patients after institution of extra-corporeal circulation. We have experienced three cases from June, 1973 to May, 1983, the patients were undergone complete repair with extracorporeal circulation at the Department of Thoracic and Cardiovascular Surgery in the Yonsei University. The ages ranged from 12 years to 14 years, all cases were supracardiac type of TAPVC. Only one case died due to bleeding from anastomosis site between LA and pulmonary venous trunk. In the remaining two patients with complete corrections of TAPVC, there was excellent relief of symptoms such as dyspnea and cyanosis. Their postoperative course have been good during follow-up.

단층촬영에 의해 획득된 흉부영상의 폐 영역은 기관지, 폐동맥, 폐정맥으로 구성된 복잡한 형태를 가지고 있다. 또한 이들 조직과 폐 영역 내에 존재하는 악성 종양과 같은 질병들 사이의 공간정보의 유사성으로 인해 방사선 전문의조차도 질병을 간단히 구분 해내는데 많은 어려움이 따른다. 따라서 본 논문에서는 이러한 유사한 공간정보를 갖는 폐 영역을 수리형태학 필터인 모폴로지(morphology)와 국부적인 워터쉐드(watershed) 알고리즘을 이용하여 분할하고, 분할된 폐 영역으로부터 색전 또는 종양 등의 결절(nodule)의 정보를 가지고 있는 혈관들을 추출하는 효과적인 알고리즘을 제안한다.
