임심 중 심폐바이패스를 사용하는 개심수술은 산모뿐 아니라 태아계에도 영향을 끼치기 때문에 중요하다. 임신 중 항응고제 투여을 부적절하게 하여 기계판막 기능부전이 초래된 임신 31주의 산모에서 심장 재수술에 앞서 제왈절개로 태아 출산 후 20시간 뒤 산모의 개시수술을 성공적으로 시행하였기에 보고하는 바이다.

From March, 1983 to June, 1994, twenty-two patients underwent coronary artery and combined operations. The ages of the patients ranged from 42 years to 72 years (mean 60.4$\pm$8.2 years). There were 17 male and 5 female patients. The left ventricular (LV) ejection fraction ranged from 25% to 65% (mean 46.9$\pm$14.2%). Nine patients had mechanical complication of myocardial infarction (MI), of which 5 were LV aneurysm, 3 ventricular septal defect and 1 mitral regurgitation. Nine patients had rheumatic valvular heart disease of whom 7 with aortic valve disease and 2 with mitral valve disease. Two other patients had left atrial thrombi, only one with atrial septal defect a d another with aneurysm of ascending aorta. An average of 2.1$\pm$1.0 bypasses was done, ranging from one to four. There were 3 postoperative complications; 2 perioperative MI and 1 leg wound infection. Among complicated patients, mortality was 1 patient (4.5%) due to low cardiac output syndrome after perioperative MI. With 3 to 136 months follow-up (mean 41.1$\pm$40.2 months), late mortality was 1 patient due to cerebral vascular accident. Among long-term survivors, all patients are in New York Heart Association functional class I or II. Although the number of patients was small, our surgical results were favorable. Therefore we think that coronary revascularization combined with heart operation does not increase the operative risk when associated coronary artery disease is present, and it reduces the occurrence of late death.

Gastrointestinal complications, especially duodenal complication after cardiopulmonary bypass are rare, but often fatal. We experienced 1 case of duodenal ulcer bleeding and 2 cases of duodenal ulcer perforation developing after cardiopulmonary bypass from August 1994 to April 1996. In the case of duodenal ulcer bleeding, palpitation, dizziness, tachycardia and melena were the clues leading to diagnosis, and in the cases of perforation, abdominal distension with pain, tachycardia, hypotension, oliguria were the clues. Duodenal perforations were diagnosed by abdominal paracentesis. The patient with duodenal bleeding was treated by H-2 receptor antagonist, antacids and transfusion. And emergency laparotomy was required for the patients with duodenal perforation. In addition to ulcer prophylaxis including H-2 receptor antagonist and antacids, a high index of suspicion and timely surgery are necessary for early diagnosis and appropriate treatment of duodenal complication developing af er cardiopulmonary bypass.

Since Jan. 26th, 32 cases of intracardiac operation had been performed during 8 months in Sejong General Hospital, Bu Cheon, Kyung Ki Province. There were 17 cases of congenital heart disease and 15 cases of valvular heart disease. Except 1 mortality case of aortic and mitral valve replacement, All patients had discharged with good results, and until now they have been followed up without problems. We report the cases and results of the operation.

da $Vinci^{TM}$ Surgical System is an advanced mode of minimal invasive surgery, using 3-dimensional imaging system and robotic arms which can mimic the dexterity of the human hand. Thus, various operations can be performed with minimal incision and limited surgical field and the merits of minimal invasive surgery can be maximized by using it. We report our first experience of robotic open heart surgery using the da $Vinci^{TM}$ Surgical System for repairing atrial septal defect.

Background: Sternal infection after open heart surgery is a serious complication associated with high rate of mortality. We reviewed the effect of improved operating room and intensive care unit un the sternal infection by analyzing the incidence and condition of that around the movement of operating room and intensive care unit in July 1997. Material and method: We reviewed a total of 453 patients. Group I contains 237 patients who underwent open heart surgery between January 1997 and December 1978 before we moved the intensive care unit and of operating room, and Group II contains 216 patients who underwent open heart surgery between January 2000 and July 2001 after we moved. We only included adult patients over age 15 who underwent cardiopulmonary bypass through median sternotomy and excluded the mortality cases except sternal infections in this study. Result: Sternal infection developed in 18 patients(8.0%) in Group I, and in only 1 patient(0.49%) in Group II. Emergency operation, cardiopulmonary bypass time, operation tilde, transfusion, tracheostomy, and reoperation are significantly associated with sternal infection among the known risk factors. The logistic regression analysis containing those six factors revealed that the movement of intensive care unit and operating roots is effective on the decreasing sternal infection(p=0.029, 95% confidence interval 0.011 ∼ 0.788). Conclusion: Although there have been studies on manly risk factors associated with the sternal infection after open heart surgery, we think that the improvement of operting room and intensive care unit is a method for decreasing the incidence of sternal infection.

Patients over 15 years of age who have undergone a surgical correction of congenital heart disease at Kyungpook University Hospital during the period of January 1990 through October 1994 have been reviewed . One hundred forty three, 22.4 % of 628 operations, which have repaired congenital heart diseases during this period were adult patients. There were 23 patients under 20 years of age, 58 between 20∼29 years, 34 between 30∼39 years, 18 between 40∼49 years, and 10 between 50∼59 years. The most common defects were atrial septal defects which accounted for 73 cases (51.1 %) and other common anomalies were ven- tricular septal defects (57 cases, 39.9 %), tetralogy of Falloffs(4 cases, 2.8%) in order of incidence. There were 10 non-fatal operative complications (6.9 %) but there was no operative mortality. This study shows the incidence of operable congenital heart diseases in adults and the fact that it could be corrected surgically with low mortality and morbidity.
