Congenital tracheal stenosis can be a life-threatening disease, especially in cases involving the long-segment of the trachea. When patients are symptomatic immediately after birth or develop an accompanying complex cardiac anomaly, surgical repair can be a considerable challenge. We experienced a tracheoplasty in one early infant weighing 2.6 kg and one neonate who had ventilator dependency from long-segment congenital tracheal stenosis and congenital cardiac anomaly. One early infant, who had diffuse stenosis of distal trachea after ventricular septal defect closure, underwent resection and extended end to end anastomosis. One neonate who had diffuse stenosis of proximal trachea with tetralogy of Fallot (TOF), underwent slide tracheoplasty with total correction for TOF Postoperative chest computed tomography showed widely patent trachea. Both infants are now well without symptoms.

Twenty eight patients with conpnital heart disuse underwent lung biopsy to assets pulmonary obstructive vascular disease at cardiac surpry. Thirteen patients had patent ductus arteriosus, 10, ventricular septal defects and S, atrial septal defects. The aaes were between 2 and 30 years. In patients with patent ductus arteriosus lung biopsy was performed from the IIngular Hlment. The anterior seament of the right upper lobe was blopsled in cases with ventricular septal defect and atrial septal defect. Grading of pulmonary obstructive vascular disease could not be assessed In 9 cases. In 2 cases poor quality of the slides made us impossible to evaluate and In 7 cases there were no suitable small muscular arteries to evaluate in the slides of lung tissue especially taken from the IIngular seament. Nineteen cases were evaluated pulmonary obstructive vascular disease. Among them 17 cases had Heath-Edwards changes of grade 1 and 2 patients had that of grade 3. The thickness of media was measured. It was expressed as percentage of medial thickness to outer diameter of artery. The medial thickness was correlated proportionally with elevation of pulmonary arterial pressure and pulmonary vascular resistance to systemic vascular resistance ratio. There were no complications related to the procedure of lung biopsy.

Down syndrome (DS) is a genetic disease known as trisomy 21. Congenital cardiac anomalies are present in about 40% of DS patients. Dental anomalies are also common among DS patients. In DS patients, canine impaction is 10 times more frequent and transposition of maxillary canine and first premolar is 50 times more common than in general population. A female DS patient with congenital heart disease was diagnosed as having a transposed impacted maxillary canine. Sectional fixed appliance with Nance holding arch was used for the orthodontic treatment. After space was regained for the eruption of the canine, orthodontic button was attached using flap operation with closed technique. Traction and alignment of the tooth followed. To prevent endocarditis, prophylactic antibiotics were prescribed for the recommended dental procedures. Total treatment time was 25 months and no complication was found.

Congenital esophageal anomaly with or without tracheoesophageal fistula was rare congenital disease.We experienced 6 cases of congenital esophageal atresia, with tracheoesophageal fistula [5 cases and one esophageal atresia without fistula, were treated in the Department of Thoracic and Cardiovascular Surgery, Kangnam Sacred Heart Hospital, Hallym university, from May, 1992 to July, 1994. The type of four cases were upper blind pouch and lower tracheo or broncho esophageal fistula and one case H-type fistula with no esophageal atresia, and the one case was esophageal atresia without fistula. We performed modified Haight`s method, one case was primary closure with feeding gastrostomy and stomach interposition. Three were died due to respiratory failure on 7 and 9th postoperative days.Three were recovered uneventfully.

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.
