We experienced a series of animal experimental studies of the total artificial heart in 1988. So called, "Korean Heart* was used in this study, which is developed and fabricated in the Department of Biomedical Engineering, College of Med., S.N.U.. "Korean Heart" is a Rolling-Cylinder Motor-Driven type which is a newly developed electromechanical heart over the shortcomes of the previous artificial hearts, especially pneumatic type. The advantages of the "Korean Heart" are total implantability, quiet and smooth movement, small size fittable in oriental people, etc. The animal experiments were performed two times, as an assist device in sheep and total artificial heart implant experiment in calf weighing 100 kg. After total implantation, the artificial heart was well functioned in movement and hemodynamic control. So that, the calf was recovered excellently, which was able to stand up by herself and take an oral intake. Total survival time was 100 hours and the cause of death was a sudden pumping failure [electrical connection problem]. Several postoperative laboratory results almost within normal limits and no hemolysis, but in autopsy, the multiple thromboembolic findings were seen at the lung and kidney.n at the lung and kidney.

Twelve patients had undergone repair of atrioventricular septal defects. Age at operation ranged from 2.4 years to 17 years[mean, 8.25 years]. Five patients were male and seven were female. Three patients had complete atrioventricular septal defect[Rastelli type A] associated with Down`s syndrome. One of the three patient with complete atrioventricular septal defect had tetralogy of Fallot. Three patients had the intermediate form and seven patients had the partial form. The primum atrial septal defect was closed with pericardial patch. The atrioventricular valve septal commissure[mitral cleft] was closed with pledgeted sutures. Three complete atrioventricular septal defect were undergone by two-patch technique. A crescent-shaped Dacron patch was used to occlude the ventricular septal defect. One patient of partial form was sudden death 5 days postoperatively. There were no another complications after surgery. One patient underwent reoperation for opened mitral cleft 2.5 years postoperatively. New York Heart Association functional class of patients was improved postoperatively.

흉부 손상후 대동맥파열이 발생하였으나 진단되지 못하다고 지내다가 만성 대통맥류가 형성될 때까지 생존하는 경우가 아주 드물게 보고된다. 대개는 아무런 증상이 없지만 흉통, 연하장애, 기침, 가래등의 기관지 자극증세 또는 돌연사등이 나타나기도 한다. 본 교실에서는 이러한 흉부 수상후 발생한 만성 대동맥류에서 비교적 드문 합병증의 하나인 대동맥기관지루를 치험하였기에 보고하고자한다. 입원후 대량 객혈이 있어 흉부전산화단층 촬영후 대동맥협부의 대동맥류와 좌상엽기기관지와의 대동맥기관지루 의심되어 응급으로 흉부 대동맥 병변부위를 인조혈관패취를 이용한 봉합술과 좌상엽절제술을 시행하였다.

A 3-year-old Jeju native black sow with sudden death was requested to the Jeju Self-Governing Provincial Veterinary Research Institute for diagnosis in July 2009. Because the pig died suddenly, we could not find any clinical signs. Gross lesions such as pulmonary edema, redness of heart, liver, kidney and lymph nodes were observed at necropsy. Histopathologically, there were severe eosinophilic meningoencephalitis, atrophy, degeneration and necrosis of laminar neurons, and neovascularization in cerebral cortex. Based on histopathological findings and history taking about temporal suspension of water supply, this case was diagnosed as salt poisoning of a Jeju native sow. In our best knowledge, this is the first report for salt poisoning of sow in Korea, especially in Jeju native pig.

Myxoma of the heart can now be successfully treated but the success is obviously dependent upon the correct diagnosis and treatment prior to development of catastrophic complications such as sudden death, embolism or cardiac failure. The right ventricular myxoma is very rare, and we treated successfully a case of giant right ventricular myxoma, sessile tumor originated from ventricular apex, weighed 175 gm. The tumor base was broad, about 3 cm x 3cm, and it was hardly adhesed to the tricuspid valvular structures, but could remove with the preservation of adequate residual ventricular chamber size and the maintenance of functional tricuspid valve anatomy. The postoperative course was excellent and uneventful.

37 years old female was admitted with chief complaints of dyspnea on exertion and hemoptysis. Past history and family history were non-contributory. Physical examination showed Grade III systolic murmur at the apex, which transmitted to the back. E. K. G. and X-ray findings were compatible with the mitral insufficiency. With small size of Beall mitral valve, mitral valve replacement was done under the cardia-pulmonary bypass using hemodilution technic. Patient was tracheotomized after operation and assisted respiration was done for four weeks. Postoperatively, all signs were fine and patient walked around the ward without any difficulty, but she was in psychotic state. On postoperative 60th day, she complained of sudden dyspnea and on chest film, tracheal stenosis was found and recannulation of the tracheal tube was made. Thereafter, she was quite fine until postoperative 110th day when she, by berself, removed the tracheal cannula and died of asphyxia. Autopsy findings of the valve showed no thrombosis, no variance of the valve, and good endothelization of the valve cuffs. Asphyxia, due to removal of the tracheal connula by herself under psychotic state, was considered to be the cause of death in this patient who had tracheal stenosis after tracheostomy.

Three patients who sustained penetrating stab wound of the heart have been treated successfully by emergency thoracotomy in the Department of Thoracic Surgery, Chonnam University Hospital. There were two knife and one glass wound. The location of the injury were all on the right ventricle, but in one patient, it was penetrated to ventricular septum. All patients were in shock with a systolic pressure under 60 mmHg when admitted to the emergency room. In one of the three patients, blood pressure was not detectable and subsequently cardiac arrest. Two patients required immediate thoracotomy because of intrathoracic hemorrhage and increased pericardial tamponade and the other one required prompt thoracotomy because of sudden onset of cardiac arrest. There were no death postoperatively. Two patients are living without any complication in 4 years and 4 weeks after operation. One who had penetrating wound to ventricular septum, turned to cardiac decompensation, but he is living now in 4$\frac{1}{2}$ years after operation. Exploratory thoracotomy should be performed immediately in all the patients in whom a penetrating wound of the heart or pericardial tamponade following a penetrating wound of the chest wall is suspected.

A female reticulated giraffe (Giraffa camelopardalis), 20-month-old, 342 kg, died at Seoul Zoo on January 2, 2009 after a stressful episode of chronic diarrhea. Given the appearances postmortem, it was strongly suspected that the giraffe suffered from malnutrition for a long time. Typical appearances of serous fat atrophy were shown on most fat tissues of body organs such as heart, bone, liver, mesentery and kidney. In this study, the sudden death that had been known as "peracute mortality syndrome" was clearly identified to have resulted from a lack of understanding the Browser's diet and general failure in giraffe husbandry. Individualized care and high quality hay must be provided to compensate higher consumption of metabolic energy and to prevent animal loss in winter season.

Cerebrovascular and cardiovascular diseases (CVDs) are a major cause of deaths among workers as well as in general population in Korea. Occupational stress like long working hours or overwork can cause sudden unexpected death in a worker who had been suffering from an aggravated preexisting condition such as hypertensive or arteriosclerotic diseases, The Korean government has compensated the cases of cerebrovascular disease and cardiovascular disease due to overwork, but neither a resonable definition of overwork nor detailed evaluation guideline has been officially provided to verify overwork, so that the prevention of, as well as compensation for workers' occupational stress-related cardiovascular attacks, cannot be carried out efficiently. A thorough understanding of the etiopathology of WR-CVDs can be very helpful in developing a prevention strategy.

Heat stroke can lead multi-organ damage with hemorrhage and necrosis in the lungs, heart, liver, kidneys, brain and Ut. Heat stroke occurs when the elevation of core body temperatures induce a failure of thermoregulatory mechanism. A four-year-old male African Lion(Panthera leo) showed clinical signs such as panting, tachycardia, hyperthermia, unconsciousness and mydriasis under He hish humidity and hot weather. Clinical treatment and pouring cool water was unsuccessful. Grossly, congestion of lungs and pleura was observed. Yellowish discoloration was observed in the renal cortex. Microscopically, the coagulative necrosis in kidney and congestion of lungs and spleen were observed. In our knowledge, this case was closely associated with acute heat stroke.
