배 경 : 급성호흡곤란으로 응급실에 내원한 환자에서 그 원인질환을 감별하는 것은 효율적인 치료에 매우 중요하나 임상양상만으로 감별진단하기는 어려운 경우가 많다. 최근에 쉽게 측정하고 확인이 가능한 생화학적 표지자인 B-type natriuretic peptide에 대해 연구가 이루어지고 있다. 방 법 : 2004년 3월부터 7월까지 한양대학교병원 응급실로 급성호흡곤란을 주소로 내원한 261명의 환자를 대상으로 혈청 BNP를 측정하였고 임상적 소견을 후향적으로 분석하였다. 결 과 : 대상환자를 증상의 원인에 따라 크게 심부전군(n=119, 382, 113-1230 pg/ml)과 비심부전군(n=142, 29, 7-81 pg/ml)으로 나누었고(사람수, 중위수, 백분위수 25-백분위수 75), 하위집단으로 심부전군은 COPD와 좌심부전이 동반된 군(n=5, 820, 354-1620 pg/ml), 폐성심군(n=3, 1650, 239-1990 pg/ml), 좌심부전군(n=111, 378, 106-1120 pg/ml)으로, 비심부전군은 COPD군(n=20, 39, 21-101 pg/ml), 기타 호흡기질환군(n=56, 59, 10-129 pg/ml), 기타 다른 원인군(n=66, 15, 6-47 pg/ml)으로 분류하였다. 혈장 BNP는 원인 질환에 따라 유의한 차이를 보였으며(p<0.001), COPD군과 좌심부전이 동반된 COPD군을 비교했을 때 심부전이 동반될 때 혈장 BNP가 의미있게 높았다(p=0.002). 당뇨병, 고혈압, 흡연 및 신부전 등 심질환의 위험인자가 없는 환자들에서 심부전의 동반 유무와 BNP값을 비교해 보았을 때, 심부전이 동반된 경우 의미있게 BNP값이 증가되어 있었다(p<0.001). 또한, BNP가 133 pg/ml이상일 경우 예민도 0.73, 특이도 0.87로 심부전에 대한 치료에 반응할 수 있는 환자군을 감별할 수 있었다. 결 론 : 혈장 BNP는 급성호흡곤란의 감별진단에서 심부전의 유무를 알아내고 효율적인 치료를 앞당기는데 유용한 검사이다. 특히, 기존의 호흡기 질환을 가지고 있거나 심장질환의 위험요인이 없더라도 BNP가 높은 수치를 보일 경우에는 심부전의 가능성을 고려해서 환자에게 접근해야 한다.

Although the conventional methods of cardiopulmonary bypass for open heart surgery have been employed, it has been usual method to repair of congenital heart disease in infancy using deep hypother-mia and circulatory arrest technique. In 1980, we reported total correction of congenital heart disease using surface induced hypothermia-total circulatory arrest and rewarming with limited cardiopulmonary bypass. in 1981, three patients below 10 kilogram, who had ASD and PDA, and two of VSD with pulmonary hypertension were operated on using simple deep hypothermia without cardiopulmonary bypass. During surface cooling, there were no ventricular fibrillation and arrhythmia. There were no difficulties to resuscitate the heart. Postoperative respiratory and neurologic complication were not occurred. Follow up examination for two to three years gave no evidence of cerebral damage due to circulatory arrest.

Dextrocardia means right-sided position of the heart in the chest irrespective of the cause. For the absolute diagnosis of the dextrocardia, the segmental analysis of heart is necessary. Once the segmental analysis of the dextrocardia is made, it is often relatively easy to identify the presence of any associated defects based on conventional methods including physical examination, EKG, echocardiography, and angiocardiography. Two cases of dextrocardia with congenital heart disease were treated surgically.A eleven - months old boy was operated under diagnosis of ASD, VSD, and bilateral SVC with mirror - image dextrocardia {I,L,I} by primary closure of ASD and VSD.A twenty-four months old girl was operated under diagnosis of ASD, VSD, and PS with corrected TGA {I,D,D} by primary closure of ASD, VSD and dilatation of pulmonary stenosis. Both of them were discharged healthily after operation.

Background: A sputum culture is the most reliable indicator of the infectiousness of pulmonary tuberculosis (PTB); however, a spontaneous sputum specimen may not be suitable. The aim of this study was to evaluate the infectious period in patients with non-drug-resistant (DR) PTB receiving adequate standard chemotherapy, using induced sputum (IS) specimens. Methods: We evaluated the duration of infectiousness of PTB using a retrospective cohort design. Results: Among the 35 patients with PTB, 22 were smear-positive. The rates of IS culture positivity from baseline to the sixth week of anti-tuberculosis medication in the smear-positive PTB group were 100%, 100%, 91%, 73%, 36%, and 18%, respectively. For smear-positive PTB cases, the median time of conversion to culture negativity was 35.0 days (range, 28.0-42.0 days). In the smear-negative PTB group (n=13), the weekly rates of positive IS culture were 100%, 77%, 39%, 8%, 0%, and 0%, respectively, and the median time to conversion to culture-negative was 21.0 days (range, 17.5-28.0 days). Conclusion: The infectiousness of PTB, under adequate therapy, may persist longer than previously reported, even in patients with non-DR PTB.

폐동맥 협착과 심실 중격 결손을 동반한 대혈관 전위를 갖는 환자들에 대한 수술은 Rastelli 수술법이나 Lecornpte 수술법이 전통적으로 시행되어 왔으나, 심실 내 터널에 의한 뒤틀린 좌심실 유출로와 부자연스러운 우심실 유출로에 의해 장기 성적은 만족스럽지 않다. 이에 대한 대안으로 저자들은 이 기형으로 진단된 3세 환아(체중 9.6 kg)에서 반회전 동맥간 전환술(half-turned truncal switch operation)을 시행하였다. 술 후 심초음파 검사에서 좌심실유출로와 우심실유출로가 곧고 넓게 형성되어 향후 좋은 장기 결과가 기대된다.

Lung transplantation is considered a viable treatment option for patients with end-stage lung disease. Recent decades have seen a gradual increase in the number of lung transplantation patients worldwide, and in South Korea, the case number has increased at least 3-fold during the last decade. Furthermore, the waiting list time is becoming longer, and more elderly patients (>65 years) are undergoing lung transplantation; that is, the patients placed on the waiting list are older and sicker than in the past. Hence, proper management during the pre-transplantation period, as well as careful selection of candidates, is a key factor for transplant success and patient survival. Although referring and transplant centers should address many issues, the main areas of focus should be the timing of referral, nutrition, pulmonary rehabilitation, critical care (including mechanical ventilation and extracorporeal membrane oxygenation), psychological support, and the management of preexisting comorbid conditions (coronary artery disease, diabetes mellitus, gastroesophageal reflux disease, osteoporosis, malignancy, viral infections, and chronic infections). In this context, the present article reviews and summarizes the pre-transplantation management strategies for adult patients listed for lung transplantation.

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.

A 2-year-old, spayed female, American shorthair cat presented with acute weight loss, tachypnea, and dyspnea. The cat had grade V holosystolic murmur and systemic hypotension. Echocardiography showed a 9 mm defect in the ventricular septum, left-to-right dominant bi-directional shunt, right ventricular hypertrophy, pulmonary stenosis, pulmonary hypertension, and overriding aorta. The cat was diagnosed with a Tetralogy of Fallot. The cat was treated with furosemide, pimobendan, ramipril, and sildenafil. Treatment reduced pulmonary infiltration, pulmonary vessel enlargement, and main pulmonary artery bulging. However, right-to-left flow increased over time and right ventricular outflow tract velocity was elevated. Currently, the patient has maintained an improved state for 1 year. This case report described a severe inherited feline Tetralogy of Fallot case that was successfully managed for a long time.

폐정맥 폐쇄성 폐고혈입증은 드문 질환이기는 하나 폐부종이 동반된 폐고혈압증에서 반드시 의심해야 하며 폐생검을 통해 확진할 수 있고, 폐조직 검사상 폐동맥의 침범이 있다해도 이질환의 가능성을 배제할 수 없다. 저자들은 폐부종을 동반한 폐고혈압증에서 심도자 검사상 폐동맥쐐기압이 정상이고 다른 심장 질환이 없는 것올 확인한 후 폐조직 생검으로 진단된 폐정맥 폐쇄에 의한 폐고혈압증을 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
