In 1980, 416 cases of open heart surgery were done in this Department with over all operative mortality of 12.3%. 1. There were 288 congenital anomalies consisting of 174 acyanotic and 114 cyanotic varieties, which showed operative mortality of 6.9% and 25.4% respectively. 2. There were 128 cases of acquired lesions, 124 valvular disease and 3 myxoma being the main lesions. 3. There were 128 cases of valve replacement with operative mortality of 7.8%. 4. The most frequently operated anomaly was VSD, 90 pure VSD and 21 cases were associated with one or 2 cardiac anomalies. Over all operative mortality in 111 VSD cases was 8.1% but in 90 pure VSD cases it was 6.7%. 5. Tetralogy of Fallot showed the highest incidence in cyanotic group with 88 cases, consisting of 68 pure and 20 with other cardiac anomalies. Over all mortality in 88 cases was 19.3% but in pure form 16.2%. 6. In 128 valve replacement cases over all mortality was 9.4%. There were 85 mitral, 11 aortic, 2 tricuspid, 21 mitral with aortic, 6 mitral with tricuspid, 3 mitral, aortic, and tricuspid valve replacement cases. For mitral valve replacement operative mortality was 5.9%. 7. Twenty-one cases of babies under 10kg body weight were operated on with over all operative mortality of 28.6%. Sixteen cases of VSD were found with operative mortality of 25%. 8. Among 128 cases of valve replacement 7 were under the age of 15 years and 12 were between 15 and 20 years old. Five pediatric cases underwent mitral valve replacement without mortality, 9 year old boy was the youngest among them. In this Department open heart surgery for infancy and complex anomalies showed still hip operative risk which should be improved in the coming years. For open heart surgery Shiley oxygenators and 2 sets of A-O de-lux 5 head roller pump were utilized exclusively. For valve replacement Ionescu-Shiley bovine pericardial xenografts were mainly used. In pediatric and rural patients Persantin with aspirin regimen was satisfactorily administered for anticoagulation after valve replacement. Routinely Coumadin was administered for one year after valve replacement* In patients who had thrombus on valve sites, chronic atrial fibrillation, and giant left atrium Persantin-Aspirin regimen was used when one year coumadin administration was discontinued.

심장 판막엽에 발생하는 혈관종은 극히 드문 질환으로 최근까지 문헌에 보고된 것은 총 5례가 전부이며 아직까지 국내문헌에는 보고된 바가 없다. 건강하던 46세 여자가 갑자기 발생한 좌측 안면마비와 수부 감각이상을 주소로 내원하였다. 신경학적 검사에서는 이상 소견이 없었으며 심장초음파에서 승모판막 전엽에 위치한 종괴가 발견되어 종괴를 포함한 승모판막 전엽의 일부를 절제한 후 자가심낭을 이용하여 승모판막성형을 시행하였다. 병리조직 검사상 승모판막 전엽에 발생한 혈관종으로 판명되어 문헌고찰과 함께 보고하는 바이다.

유두상 섬유탄력종은 양성 심장 종양 중 두번째로 많이 발생하며, 주로 대동맥 판막이나 승모판막에 발생한다. 그러나, 폐동맥 판막에서 발생한 경우는 아주 드물게 보고되고 있다. 이에 저자들은 심부전증 환자에서 판막 치환술로 치료된 폐동맥 판막의 유두상 섬유탄력종을 드문 증례로 보고하는 바이다.

유두상 섬유탄력종은 원발성 종양 중 두 번째로 많이 호발하는 양성종양으로 주로 심장판막에 발생한다. 본원에서는 흉통과 호흡곤란을 주소로 내원한 61세 여자 환자에서 발견된 대동맥 판막에 위치한 유두상 섬유탄력종을 경험하였다. 대동맥 판막의 손상 없이, 개심술 하에서 대동맥 판막에 부착된 종양을 제거한 치험을 문헌고찰과 함께 보고하는 바이다.

Mitral regurgitation is the most frequent cause of cardiac disability and death in dogs. A wide range of medical and surgical treatments have been used for mitral regurgitation. Surgical treatments for complete correction of mitral regurgitation include valve repair and valve replacement, which have the advantages of eliminating or correcting the primary cause. Surgical treatments approach the mitral valve via right- or left-side thoracotomy. Aortic root exposure is needed for cardiopulmonary bypass. To compare right-side and left-side approaches, 10 dog cadavers were used in this study. Subsequently, the left-side surgical approach was used in vivo and in conjunction with cardiopulmonary bypass and cardioplegic arrest. Based on the results, and considering ease of access to the aortic root, valve incision site, and visualization of the surgical field, a left-side approach is recommended.

Recently, cardiac injury due to blunt thoracic trauma appears to be increasing in frequency. The rising incidence of this mishap may relate to the absolute increase in automobile accidents as well as to more universal recognition that cardiac damage may have been sustained. We have experienced a rare case of ventricular septal defect caused by non-penetrating thoracic trauma. Of further interest is the history of chest trauma, clearly resulting in rupture of the chordae tendineae of the tricuspid valve successfully treated by operation-re-placement with two, 6 - 0, double-armed, expanded polytetrafluoroethylene sutures-2 months later. The unique combination of ventricular septal defect and rupture of the chordae tendineae of the tricuspid valve secondary to non-penetrating thoracic trauma is presented below to emphasize another variety of cardiac injury.

Autologous blood transfusion is a common method of reducing the need for homologous blood transfusion during cardiac operations. Between June 1991 and May 1992, 12 cases [Group I] were experienced autologous blood transfusion using Cell Saver undergoing double valve replacement or redo-valve replacement. Control group [N=12, Group II] was selected to above similar operation during same period. The Cell Saver system [Haemonetics Corp.] was employed for autologous blood transfusion. The blood shed in the operative field before and after cardiopulmonary bypass and remained cardiotomy reservior was aspirated by means of a locally heparinized collecting system. After centrifused salvaged blood, the resulting red cell concentrate reinfused subsequently. The patient receiving autologous blood transfusion required significantly less homologous blood transfusion than their control group. [Group I; 3519 $\pm$ 869, Group II; 4622 $\pm$ 856, Respectively; P=0.005] There were no clinical infections in the autotransfusion group. And there was no apparent intergroup difference of the clinical findings, hematologio datas and coagulation parameters. We conclude the autotransfusion using Cell Saver is effective for reducing of the hom-ologlous blood transfusion in cardiac surgery.

Approximately 5 percent of infective endocarditis are limited to the right side of the heart, the tricuspid valve being the usual site of involvement. Usually there is no underlying cardiac disease, and the vegetations occur on previously normal tricuspid leaflets. This paper reports a case of bacterial endocarditis involving the bio-tricuspid valve in a patient with tetralogy of Fallot, and who required prosthetic valve replacement in addition to surgical therapy for the congenital lesions.

Penetrating chest trauma may result in significant intracardiac injury. A traumatic ventricular septal defect is a rare complication that requires surgical management, particularly if heart failure ensues. We report a case of delayed repair of an outlet-type ventricular septal defect and perforation of the aortic and pulmonary valve leaflets following a stab wound. This report highlights diagnostic and surgical considerations and also presents an opportunity to review the conotruncal anatomy, which may be relatively unfamiliar to many adult cardiac surgeons.

Dynamic left ventricular (LV) outflow tract obstruction is a characteristic feature of hypertrophic cardiomyopathy; however, it can also occur in association with hyperdynamic LV contraction and/or changes in the cardiac loading condition, even in a structurally normal or near-normal heart. Here, we report a case of anemia-induced systolic anterior motion of the mitral valve and the resultant intraventricular obstruction in a patient who underwent coronary artery bypass grafting and suffered from anemia associated with recurrent gastrointestinal bleeding.
