The efficacy of cold blood potassium cardioplegia during periods of ischemic arrest was assessed in 88 patients undergoing open heart surgical procedures at Chonnam National University Medical School from December, 1987 to January, 1989. The purpose of this study was to determine if the aortic cross clamping time[ACCT] over 120 minutes correlated with operative mortality, incidence of postoperative ventricular tachyarrhythmias, needs of postoperative inotropic support and serum enzyme levels. The patients were divided according to aortic cross clamping time[less than 120 minutes and 120 minutes or greater]. The results were as follows: 1. The operative mortality was 3.2% in ACCT<120min group and 7.7% in ACCT>120 min group. 2. The incidence of postoperative ventricular tachyarrhythmia was 1.6% in ACCT <120min group and 11.5% in ACCT>120min group[p<0.05]. 3. The incidence of postoperative inotropic support in congenital heart disease was 13.0Fo in ACCT<120min group and 45.0%o in ACCT>120min group[p<0.05]. The incidence in acquired heart disease was 26.0% in ACCT<120min group and 40.0% in ACCT> 120min group. 4. After cardiopulmonary bypass, serum GOT, LDH, CPK and CPK - MB were elevated prominently. Children showed higher value of the enzymes examined than adults did before and after cardiopulmonary bypass. In congenital heart diseases, postoperative serum GOT, LDH, CPK and CPK - MB levels of ACCT>120min group were significantly higher than those of ACCT<120min group. Postoperative serum GOT, LDH and CPK - MB levels of ACCT>=120min group were significantly higher than those of ACCT<120min group also in acquired heart diseases. The results suggest that the myocardial protective effect with cold blood potassium cardioplegic solutions was not sufficient when the aortic cross clamping time was over 120 minutes.

Seventeen patients of the congenital pulmenic stenosis were operated at the department of Thoracic Surgery, Seoul National University Hospital. There were thirteen male and four females, and ranging from six to thirty years of age. And it's incidence was 2.7% of congenital heart disease cases that were operated on. (Total 628) Seven case of trilogy of Fallot were excluded. Two cases of bacterial endocarditis were found. Right heart catheterization was done in all patients. Average right ventricular pressure was $121{\pm}35.8$mmHg, pulmonary artery $20{\pm}6.8$mmHg, and RV-PA pressure gradient $98{\pm}34.5$mmHg. The preoperative average time interval of A2-P2 which was checked at phonocardiography was $0.08{\pm}0.016$second, and was reduced to $0.03{\pm}0.009$second postoperatively. One was operated by Varco's procedure, another one was done by Brock's procedure, and fifteen patients were done by open heart surgery with heart-lung machine. Pure valvular stenosis was found in sixteen and infundibular stenosis in one case. And the combining anormalies were two patent ductus arteriosus, two patent foramen ovale, and one tricuspid valve hypoplasia. Two expired postoperatively at the begining stage of cardiac surgery in this Department. The remaining fifteen showed excellent operative results.

Supravalvular aortic stenosis was relatively uncommon form of congenital heart disease. This patient had typical "elfin faces" with mental retardation, and supravalvular aortic stenosis. The diagnosis was confirmed by pressure tracing obtained at retrograde left heart catheterization and aortography. The type of supravalvular aortic stenosis was localized hourglass narrowing, which was treated by insertion of prosthetic gusset placed across the area of narrowing under the cardiopulmonary bypass.ry bypass.

This study reviewed useful aspects of the intraoperative transesophageal echocardiography among the patients in whom heart surgery were undertaken between January 1996 and July 1996 at St.Pauls hospital, Medical College of Catholic University, Seoul, Korea. During that period, 61 patients were operated on because of valvular heart disease(25 patients), coronary artery disease(22 patients), congenital heart disease(13 patients), and combined coronary artery disease and valvular heart disease(1 patient). Two patients(1 redo-VSD and 1 valvular heart diease) needed repeated aortic cross clamping and complementary procedures because of incomplete initial procedures. There was no incidence of air embolism. We could observe significant relationship of cardiac output monitoring methods either by thermodilution technique and transesophageal echocardiography by linear regression analysis(p<0.001). We tested myocardial response(percentage of systolic wall thickness, PSWT) with low dose dobutamine challenge to predict post-CABG myocardial perfusion. And the test showed statistically significant resp.onse(sensitivity 76%, specificity 94.7%, positive predictive value 95%, negative predictive value 75%). These results suggest that cardiac surgeon could draw more benefits by intraoperative transesophageal echocardiography.

From 1958 up to the end of April 1980, during the period of 12 years 1640 cardiac surgery cases including 1069 open heart surgery and 304 valve replacement cases, were operated in this Department. There were 1070 congenital anomaly and 570 acquired disease cases. In 1070 congenital anomaly cases 673 acyanotic and 397 cyanotic anomaly patients were noted. In acquired diseases 94 pericardial and 456 valvular cases were found. Among 456 valve cases 189 mitral stenosis, 133 mitral insufficiency, 30 aortic valve lesion, 97 double valve, and 7 triple valve lesion patients were noted. Among 304 valve replacement cases 209 mitral, 34 aortic, 5 tricuspid, 34 aortic with mitral, 20 mitral with tricuspid, and 2 triple valves were replaced. Annual increase `of open heart surgery cases and decrease of operative deaths were remarkable in recent years. In recent years Shiley** oxygenator in pump-oxygenator set up and Ionescu** bovine pericardial xenograft bioprosthesis were used for valve replacement mainly.

The anomaly which the right pulmonary artery originates from the ascending aorta is a rare and usually fatal form of congenital heart disease. This lesion is often associated with a patent ductus arteriosus. Death frequently occurs in early infancy. Anomalous origin of the right pulmonary artery is much more common than anomalous origin of the left pulmonary artery. The anomalous right pulmonary artery usually arise from the posterior aspect of the ascending aorta close to the aortic valve. We report a 1 month-old infant with right pulmonary artery arising from the ascending aorta, which was corrected successfully by direct anastomosis to the main pul onary artery.

There are still some controversies regarding one stage repair of pectus deformity with congenital heart disease due to probable complications after extensive resection of deformed cartilages. We performed Nuss operation with simul-taneous intracardiac repair in 8 year old patient with pectus excavatum and partial atrioventricular septal defect. The result of operation was satisfactory without prolongation of operation time, bleeding or instability of chest wall.
