Patients over 15 years of age who have undergone a surgical correction of a congenital cardiac malformation during period of January 1958 through January 1986 have been reviewed. During this period there were 3957 congenital cardiac lesions consisting of 2712 acyanotic and 1245 cyanotic cases. Among them, a total of 725 adults [18.3%] with a variety of congenital heart lesions, 548 acyanotic group and 177 cyanotic group were operated on. 372 patients were male and 252 patients were female. There were 280 patients under 20 years of age, 206 between 20-24 years, 102 between 25-29 years, 48 between 30-34 and 89 over 35 years. The most common defects were atrial septal defect which accounted for 207 cases [28.6%] and other common anomalies were VSD [140 cases, 19.3%], TOF [136 cases, 18.6%], PDA [120 cases, 16.6%] and PS [33 cases, 4.6%] in order of incidence. Overall operative mortality for this series was 3.6% [1.8% of a cyanotic group and 9.0% of cyanotic group] compared with 2.8% of total cases of congenital heart disease [acyanotic group 1.1% and cyanotic group 6.5%]. This reviewed series reveals the incidence of operable congenital heart defects appearing in any adult life and demonstrates that surgical repair can be accomplished with a satisfactory low mortality rate.

131 cases of open heart surgery were performed in the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital in 1985. There were 116 congenital cardiac anomaly and 15 acquired heart diseases. Out of 116 congenital cardiac anomaly, 73 cases of acyanotic group and 43 cases of cyanotic group were noted. In 73 cases of acyanotic group, 17 ASD, 52 VSD and 4 other acyanotic anomaly were noticed. In 43 cases of cyanotic group, 4 Trilogy of Fallot, 34 TOF, 1 Pentalogy, 3 DORV and 1 DCRV were included. Of the 15 acquired valvular heart disease cases, individual incidence was in mitral valve 10, double valve 3, and simple aortic valve 2 cases. Total number of valve replaced was 16, and 13 for mitral, 2 for aortic, and 1 for tricuspid in position, including 1 cases of double valve replacement. Overall operative mortality for 131 cases of open heart surgery was 4.5%, and the operative mortality was 5.5% in congenital acyanotic group, 2.3% in congenital cyanotic group, 0% in TOF group and 6.7% in acquired group.

Purpose: The purpose of this study was to determine the relationships among health related quality of life and uncertainty in adult patients with congenital heart diseases. Methods: The subjects were 136 adult congenital heart disease patients at the congenital heart center out-patient clinic of the A General Hospital in S city. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression. Results: There were significant negative correlations of quality of life with general motor function area and uncertainty. Among predictors, gross motor(${\beta}=-.38$) and daily activity (${\beta}=-.21$) had statistically significant influences on uncertainty(F=6.15, p=.018). Conclusion: Nursing interventions to promote gross motor and daily activity might be essential for adult patients with congenital heart disease in order to reduce uncertainty.

Background: This study aimed to present the short- and midterm outcomes after complete atrioventricular canal defect (CAVC) repair using a single-patch technique. Methods: This study included 30 children who underwent surgical correction of the CAVC using a single-patch technique. Results: The median age of the patients was 5.7 months (interquartile range [IQR], 5.0-7.5 months), and 23 patients (76.7%) had type A CAVC. Fourteen patients (46.7%) were female and 17 (56.7%) had been diagnosed with Down syndrome. The in-hospital mortality rate was 0%. No deaths were observed during a median follow-up of 4 years (IQR, 3.5-5.0 years). Patients without Down syndrome were associated with late moderate mitral regurgitation (MR) (p=0.02). Late MR less than moderate degree was observed in 96.6%, 78.5%, and 50% of patients after 2, 4, and 5 years of follow-up, respectively, while late tricuspid valve regurgitation less than moderate degree was observed in 96.7%, 85.9%, and 59.0% of patients after 2, 4, and 6 years of follow-up, respectively. After a median follow-up of 4 years, only one patient had required surgical repair of a left ventricular outflow tract obstruction, which occurred 26 months after the first operation. Multivariable logistic regression analysis adjusted for the type of CAVC, sex, Down syndrome, age, and weight revealed that the absence of Down syndrome was a risk factor for late moderate MR (MR-2) (odds ratio, 0.05; 95% confidence interval, 0.006-0.50; p=0.01). Conclusion: A single-patch technique for CAVC surgical repair is a safe method with acceptable short- and midterm results.

Recently, radionuclide angiocardiogram is one of the most common procedure for assessment of ventricular performance due to its distinctive advantages such as safety, accuracy, and ease of repeated studies. Also, measurement and comparison between pre and postoperative left ventricular ejection fraction [LVEF] are meaningful for assessing the severity of myocardial damage which occurred during open heart surgery and the status of myocardial recovery. We obtained pre and post operative LVEF using radionuclide angiocardiogram on 30 patients composed of atrial septal defect, ventricular septal defect, cyanotic congenital heart disease, and valvular heart disease who undergone the open heart surgery from March to august 1984. The study revealed that ventricular septal defect and mitral valvular heart disease showed 8.1% and 6.2% decreases of postoperative LVEF, respectively. But, there are little increases of postoperative LVEF in the atrial septal defect and cyanotic congenital heart disease. In ventricular septal defect, each group of Qp/Qs over 2.0 and systolic pulmonary artery pressure over 50mmHg showed significant 17% and 14.7% decreases of postoperative LVEF, respectively. Considering the duration of the aortic cross clamping times and closing methods of VSD, each group of duration over 30 min. and of patch closure showed 13.9% and 14.2% decreases of LVEF between pre and postoperative status respectively which was significant finding statistically.

From Feb. 1985 to Aug. 1996, 450 patients underwent open heart surgery with hypothermic cardiopulmonary bypass. In 450 cases of open heart surgery, 222 cases(49.3%) were congenital heart diseases and 228 cases(5 .7%) were acquired heart diseases. In 222 cases of congenital heart diseases, there were 201 cases of acyanotic heart disease and 21 cases of cyanotic heart diseases. Among the 228 cases of acquired heart diseases, most cases were valvular heart diseases in which 206 valves were implanted. There were 32 cases of ischemic heart disease and the average graft anastomoses were 2.37 sites per operation. The operative mortality of congenital and acquired disease was 9.0% and 10.l% respectively and then overall mortality rate was 9.6% .

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.
