Communications of coronary arteries with the cardiac cavities have first time been described by Krause in 1865 in a case of an accessory artery draining into the pulmonary artery and later Cayla in a case of a right coronary artery entering the right ventricle. The initial cases have been found accidentally at autopsies, however In recent years after the Introduction of angiography and coronary arteriography, the malformation Is diagnosed during life and is corrected surgically. These conditions are unusual entitles since the advent of angiography they are being diagnosed with increasing frequency. Three patients who had surgical correction of coronary-cardiac chamber fistula at our hospital are presented. In the first case and second case, coronary arteriovenous fistula was corrected horizontal mattress suture ligation with pladget under the cardiopulmonary bypass and third case was corrected double ligation with cardiopulmonary bypass standby. The postoperative courses were uneventful. They discharged without any fistula related complica-tions.

This is a report of a case in which a left atrial myxoma was successfully removed by total cardiopulmonary bypass with total hemodilution and moderate hypothermia. The patient was a 17 old girl with mitral valvular symptoms that occured suddenly three months prior to operation. After the onset of symptoms. it was progressively aggravated to serious general condition. The preoperative diagnosis of left atrial tumor was made from echocardiography. and the tumor was confirmed as myxoma by the histopathological examination of the tumor tissue removed during operation. The myxoma was unusually originated from posterior wall of the left atrium. which was located between drainage orifices of right and left pulmonary veins, The tumor developed in the left atrial cavity and one of the polypoid processes of the myxoma was prolapsed into the the left ventricle through the mitral orifice. Following operation. there was no evidence for peripheral vascular embolism, and all valvular symptoms disappeared. The postoperative course was uneventful.

A experimental study of deep hypothermia for open heart surgery in 5 dogs was reviewed. Surface hypothermia in combination with limited cardiopulmonary bypass was employed. Circulatory dynamics were well maintained following cardiac arrest during one hour at $20^{\circ}C$. Some degree of acidosis usually developed after the arrest period but was gradually corrected during. rewarming Total circulatory occlusion could be maintained for at least one hour at $20^{\circ}C$ without evidence of cerebral damage in the dogs. Potassium in the serum after deep hypothermia was moderately decreased and it was the most severe change in the electrolyte. Free hemoglobin of serum was mild increased and it was one of advantages of combined hypothermia with limited cardiopulmonary bypass.

Plasma protein concentration, plasma albumin concentration, hematocrit, and arterial blood gas tension were measured in 15 mongrel dogs undergoing heart transplantation with cardiopulmonary bypass. The hemodilution due to priming solution resulted in a 49% decrease in plasma protein concentration, a 57% decrease in plasma albumin concentration, a 46%a decrease in hematocrit. The measurements had returned to preperfusion values 1 hour after the end of cardiopulmonary bypass. The intraoperative changes in plasma protein and albumin concentration did not correlate with changes in alveolar-arterial oxygen tension gradients[D[A\ulcorner PO2]]. It is concluded that, in the absence of an increase in left atrial pressure, marked decrease in plasma protein concentration can be tolerated without the occurrence of pulmonary edema. And further study should be done to determine how to prepare an ideal priming solution.

체외순환 후 heparin의 항응고효과를 중화시키기 위해 널리 사용되는 protamine에 대한 아나필락시스 반응은 매우 드물다. 하지만 그 결과는 매우 치명적일 수 있으며, 아직도 정확한 발생기전이 알려져 있지 않다. 당뇨병이 없는 57세 여자 환자가 승모판막 치환술 및 극초단파(Microwave)를 이용한 Maze 술식을 시행 받은 후 protamine에 의한 심각한 아나필락시스 반응이 발생하여 증례 보고하는 바이다.

Purpose: The purpose was to test the effects of cardiopulmonary resuscitation competency program on knowledge of CPR, self-efficacy, and the skills of CPR of nursing college students. Method: A convenience sampling of non-equivalent control group was used. Nursing college students were assigned either to conventional CPR education(N=28) or to intervention that involved a conventional CPR education and CPR competency program(N=28). CPR competency program was focused to enhance the self-directed learning on CPR training. Result: There were no significant differences on the CPR competency of knowledge and self-efficacy between experimental and control groups. However in the skills competency of CPR, there were significant differences between two groups. Conclusion: It is promising that CPR competency program can be effective to increase the skills of CPR of nursing college students.

In the cardiopulmonary support system with an ECMO (extracorporeal membrane oxygenation), a higher pump head is demanded for a blood pump. In order to realize a blood pump with higher pump head, higher anti-hemolysis and thrombosis performances, a study on the development of unprecedented multistage blood pump was conducted. In consideration of the application of the blood pump for pediatric patients, a miniature two-stage centrifugal blood pump with the impeller's diameter of 40mm was designed and the performance was examined in experiments and computations. Some useful knowledge for a design of the blood pump with higher anti-hemolysis and thrombosis performances was obtained.

Successful emergency pulmonary embolectomy with the cardiopulmonary bypass was performed in a 41 \ulcorneryear old male who suffered massive pulmonary embolism after longterm bed rest due to the injury of left knee. Temporary cardiopulmonary bypass provided 120 minutes of circulatory support while complete removal of bilateral pulmonary emboli accomplished using Forgarty catheter and Gall stone forceps. Also, manual compression of the lungs was necessary to remove distal branching emboli. The patient had smooth and uneventful hospital course without complications and discharged from hospital taking coumadine on the 13th day after the operation.

정부 기관 및 식도 관통 손상은 높은 이환율과 사망률을 동반할 수 있으므로 적절한 진단 및 치료방법을 선택하는 것이 중요하다. 기관 및 식도의 복합손상을 가진 한 환자에서 체외 순환을 이용해 봉합수술을 시행하였고 만족할 만한 결과를 얻었다. 경부의 깊은 손상으로 인한 출혈과 감염을 미리 조치할 수 있다면 기관과 식도의 관통산 때 체외순환을 이용하여 수술하는 srjt이 안전한 치료방법이 될 수 있다고 생각된다.
