A 8 year old male was admitted to the Department of Thoracic Surgery, Korea University Hospital on June 22, 1978. The chief complaints were cyanosis and exertional dyspnea since at birth. EKG shows BVH and dextrocardia, phonocardiogram revealed the accentuation of second heart sound in aortic area. Echocardiogram from the left ventricle to the base of the heart, there is a discontinuity between the ventricular septum and the anterior aortic margin with a large aortic root & aortic overriding. His cardiac catheterization data and cardiac angiogram shows situs inversus totalis, dextrocardia, right aortic arch, large ventricular septal defect etc., and finally diagnosed Truncus Arteriosus. Edwards type IV with retrograde aortogram and selective bronchial angiogram. This is the first operative case reported as Rastelli operation for Truncus Arteriosus type IV in the literatures in Korea. Authors have experienced I case of Truncus Arteriosus, Edward type IV and Rastelli operation with Dacron Arterial Conduit Graft under cardiopulmonary bypass on July 3, 1978. The procedures were as follows; 2] Cardiopulmonary bypass: Origin of bronchial arteries excised from descending aorta bilaterally; defects in aorta closed. 2] Horizontal incision made high in right ventricle. 2] Ventricular septal defect [Kirklin type I+II] closed with Teflon patch. 4] Bifurcated dacron arterial graft with pericardial monocusp sutured to the bilateral pulmonary arteries. [Diameter 9 mm: Length 7 cm]. 5] Proximal end of the conduit graft anastomosed to right ventricle. [Diameter 19 mm: Length 5 cm]..Total perfusion time was 220 min. The result of operation was poor due to anastomotic leakage and increased pulmonary vascular resistance resulting acute right heart failure. The patient was died on the operation table. Literatures were briefly reviewed.

An 18-day-old male neonate with hypoplastic left heart syndrome underwent surgical intervention by modification of the Norwood procedure on September 23, 1986. Hypoplastic left heart syndrome is a serious congenital cardiac anomaly that has a fatal outlook if left untreated. Included in this anomaly are [1] aortic valve atresia, and hypoplasia of the ascending aorta and aortic arch, [1] mitral valve atresia or hypoplasia, and [3] diminutive or absent left ventricle. Patent ductus arteriosus is essential for any survival, and there is usually a patent foramen ovale. Coarctation of the aorta is frequently associated with the lesion.z With a limited period of cardiopulmonary bypass, deep hypothermia, and circulatory arrest, the ductus arteriosus was excised. The main pulmonary artery was divided immediately below its branches, and the distal stump of the divided pulmonary artery was closed with a pericardial patch. The aortic arch was incised, and a 1 5mm tubular Dacron prosthesis was inserted between the main pulmonary artery and the aortic arch. A 4mm shunt of polytetrafluoroethylene graft was established between the new ascending aorta and the right pulmonary artery to provide controlled pulmonary blood flow. Following rewarming, the heart started to beat regularly, but the patient could not be weaned from cardiopulmonary bypass. At autopsy, the patient was found to have hypoplasia of the aortic tract complex with mitral atresia and aortic atresia. A secundum atrial septal defect was noted. Right atrial and ventricular hypertrophy was present, and the left ventricle was entirely absent. Although unsuccessful in this case report, continuing experience with hypoplastic left heart syndrome will lead to an improvement in result.

Cox-Maze III 술식이 심방세동의 전형적인 수술요법이지만 탁월한 수술성적임에도 불구하고 수술의 복잡성, 장시간의 체외순환, 술 후 출혈의 위험부담으로 보편적이지는 못하다. 최근 들어서 심방세동의 병리기전에 대한 이해와 절개 및 봉합의 대안으로 여러 가지 에너지원의 개발로 인하여 Cox-Maze의 변형술식이 급격하게 발전되고 있다. 본원에서는 심폐기를 사용하지 않고 극초단파(microwave)를 이용하여 심방세동을 교정한 후 33개월 현재 양호한 상태로 동율동을 보이고 있어 문헌 보고하는 바이다.

심박동기는 동기능 부전 증후군에서부터 완전 방실차단까지 서맥의 치료에 가장 보편적으로 사용되는 중재적 치료다. 일반적으로 경정맥을 통한 심내 심박동기를 많이 사용하고 있으나 감염 및 혈전증, 박동기의 기능부전, 부정맥, 심근천공, 삼첨판 폐쇄부전증 등의 합병증이 발생할 수 있다. 심박동기의 감염은 전신감염으로 이행되어 환자 상태가 빠르게 악화될 수 있으므로 감염으로 의심되면 제거하는 것이 원칙이다. 추나 올가미 등을 이용한 방법등 비수술적인 방법외에도 체외순환을 이용한 적극적인 제거도 환자 상태에 따라 고려해야 할 것이다. 감염된 심박동기를 체외순환을 이용하여 제거한 두 개의 증례를 보고하는 바이다.

Fructose-l, 6-diphosphate as an additive to cold crystalloid cardioplegia [St. Thomas sol.] was studied prospectively in 60 patients undergoing open heart surgery from January 1, 1991, to June 30, 1991. Thirty patients received cardioplegia with FDP[group I ] and 30 patients received cardioplegia without FDP [group II ]. There were no differences between two groups pre-operatively with regard to age, heart disease, cross-clamp time, cardiac enzymes, or hemodynamic measurements [p>0.05]. Cardiopulmonary bypass was established using ascending aorta and vena cava cannulation employing moderate systemic hypothermia [30oC nasopharyngeal temperature] and hemodilution All patients received cardioplegia through the aortic root at aortic root pressure of 80mm Hg. The composition of the cardioplegic solution and its delivery were identical in both groups except for the addition of FDP[1.5 mg/mL] in group I. The cardioplegic infusate consisted of St. Thomas Hospital solution. The initial dose was infused through the aortic root. Topical myocardial cooling with saline slush was employed in all patients. Recorded operative data were cardiopulmonary bypass and cross-clamp times, amount of cardioplegic infusate. Blood samples for assessment of lactate dehydrogenase [LDH], creatine kinase [CK] and transaminases [GOT, GPT] were obtained before and at 1,2,3,7th postoperative period. Better myocardial protection effect was noted in group I than group II with respect to the % change of cardiac enzymes, although the differences were not significant. We conclude that FDP is a safe additive to crystalloid cardioplegia and may be beneficial in open heart surgery patients.

혈관확장성 쇼크(Vasodilatory shock)는 혈관마비 증후군(vasoplegic syndrome), 심폐바이패스후 혈관마비(post-cardiopulmonary bypass vasoplegia)라고도 불리며, 개심술 직후 나타나는 저혈압, 빈맥, 정상 또는 약간 증가한 심박출량 및 체혈관저항 감소 등을 특징으로 하며, 일반적인 수액공급이나 카테콜아민 혈관수축제(cathecolamine vasopressor)에 대한 반응이 적거나 거의 없기 때문에 개심술후 높은 이환율 및 사망율을 나타내는 상태를 말한다. 저자들은 개심술후 혈관확장성 쇼크(vasodilatory shock)로 진단되는 3명의 환자들에서 저용량의 아르기닌 바소프레신(AVP)를 사용하여 성공적으로 치료하였기에 관련된 문헌 고찰과 함께 보고하는 바이다.

Extracorporeal circulation leads to functional disorder and structural damage of organs, especially hematologic and pulmonary system, mainly by sequestration of neutrophils and deposition of macrophages at lung. Then, proteases are secreted, which insult vascular basement membrane of pulmonary capillary and alveolar septa of the lung. Among these, the most important protease at lung is elastase, because major component of lung is elastin. For prevention of lung injury, inactivators or antidotes to elastase should be necessary and Alpha 1-Proteinase Inhibitor is the elastase inactivator. Clinical experimental study was carried out to investigate the immediate postoperative change of serum Alpha 1-PI level following cardiopulmonary bypass for 20 heart cases [congenital 16 cases, acquired 4 cases] and 10 control [subtotal gastrectomy] cases. Also preliminary study was performed for 31 cases of open heart patients. The results were as follows: l. Immediate postoperative serum levels of Alpha 1-PI was significantly decreased at open heart surgery group [P< 0.005], but not decreased at control group. 2. There were no significant difference in change of serum Alpha 1-PI level between and membrane and bubble oxygenator group.Z 3. There were no significant difference in changes of serum Alpha 1-PI level between CHD and AHD. Alpha 1-PI is consumed at lung during cardiopulmonary bypass and increase after operation compensatedly and protect multiple organic damage especially lung. Therefore, Alpha 1-PI can be indicator for evaluation of prevention and treatment of pump-lung syndrome.

42세 남자환자가 내원 3개월전부터의 호흡곤란, 복부팽만 및 식욕부진으로 내원하였다. 이학적 검사상 심잡음이 청진되어 심초음파를 시행한 결과, 좌심방 혈전을 동반한 승모판협착증 및 삼첨판폐쇄부전이 진단되어 수술전 헤파린 지속 주입을 시작하였다. 내원 11일째 혈소판수치가 감소하여 시행한 항체검사 및 혈소판응괴능 검사에서 음성이 나왔지만 임상적으로 헤파린 기인성 혈소판감소증을 진단하였다. 수술중 심폐우회술시 헤파린 대체약물인 히루딘(hirudin)을 사용하였으며, ACT, aPTT를 측정하며 수술대에서 육안적으로 혈전형성여부를 확인함으로써 성공적으로 수술을 하였다, 수술 중 및 수술 후 헤파린 접촉은 없었으며, 수술 후 과다 출혈 및 전신적 혈전색전증 등의 합병증은 발생하지 않았다.
