A 38-year-old female patient with a history of tetralogy of Fallot repair at 10 years of age underwent pulmonary valve replacement with a mechanical prosthesis, tricuspid annuloplasty, and right ventricular outflow tract cryoablation due to pulmonary regurgitation, tricuspid regurgitation, and multiple premature ventricular contractions with sustained ventricular tachycardia. After surgery, she had an uneventful postoperative course with arrhythmia monitoring. She was discharged without incident, and a follow-up Holter examination showed a decrease in the number of ventricular ectopic beats from 702 to 41.

The records of 248 patients over 16 years of age who had undergone a surgical correction of a congenital cardiovascular malformation during the period of 10 years from August, 1978 to July, 1988 were reviewed. During this period, the incidence of congenital cardiovascular malformation in adult was 18.2% of 1376 total heart disease operated on and 25.5% of 986 congenital heart defects. Among them, there were 200 patients in acyanotic group and 48 patients in cyanotic group. Male versus female ratio was 1:1.28. The oldest patient was 59 years old female who had atrial septal defect. The mean age was 24.4 years old. The distribution of the lesions showed a large preponderance of atrial septal defects [37.19o] followed in frequency by ventricular septal defects [918.1%], patent ductus arteriosus [17.3%], tetralogy of Fallot [16.1%], and a variety of other complex malformations[3.2%]. In the pediatric age group, relative frequency was different from that of this adult group, showing ventricular septal defects, tetralogy of Fallot, patent ductus arteriosus and atrial septal defects in order of incidence. The hospital mortality and late mortality were 6.0% and 1.7% respectively. The causes of hospital death were low cardiac output in 10 patients, arrhythmia in 2, air embolism in 1, sepsis in 1 and respiratory failure in l. Clinical improvement upto NYHA functional class I or II postoperatively has been achieved and sustained in all patients following repair except the patients of late death and receiving reoperation. This result confirms that congenital heart defects in the adults can be corrected with a good outcome and an aggressive operative approach seems justified.

In Tetralogy of Fallot, the most common congenital cyanotic heart disease, the mortality is decreasing continuously with adequate type and timing of operation. At S.N.U.H., 195 patients were operated from January 1982 to December 1983 and 176 patients among them were analysed in the view of pre-operative pulmonary arterial condition measured by cardiac cineangiogram. The most common associated anomaly was PFO and ASD and they did not affect the postoperative course and mortality. The overall mortality rate was 8.5% in 1982 and 6.8% in 1983 but under 2 years of age, the mortality rate was relatively high as 25% in 1982 and 16.7% in 1983, and when transannular patch widening of Right Ventricular Outflow Tract was used, the mortality rate was 12.5% in 1982 and 27.3% in 1983. Preoperative angiographic measurements of the pulmonary arterial status for prediction of the ratio between the Left Ventricular and Right Ventricular peak systolic pressure were calculated retrospectively according to the Blackstones formula, and the predicted value of PRV/LV greater than 0.6 carried apparently high complication and mortality rate as 16.6% M.R. in 1982 and 11.1 % in 1983. Among postoperative complications, c-RBBB occurred most frequently about 50% but did not influenced to mortality, Low Cardiac Output Syndrome was developed in about 40%. If we select the patient who should have the staged operation including shunt operation and choose the type of RVOT relief, we expect the improvement of postoperative clinical results.

Nitrofen [2,4-dichlorophenyl-P-nitrophenyl ether] is a diphenyl ether herbicide used for pre and post-emergent control of broad leafed weeds. This chemical was known to induce a variety of congenital cardiovascular anomalies with diaphragmatic hernia and hydronephrosis in the rate fetuses. The present study was conducted to produce congenital cardiovascular anomalies in the rat fetuses by oral nitrofen administration at the indicated doses and days of gestation, and to find the characteristics of nitrofen-induced cardiovascular anomalies. All the observed fetuses were removed from the pregnant Sprague-Dawley rats sacrificed on the twenty-first day of gestation. They were preserved in 10 per cent formalin and dissection for examination were carried out under a dissecting microscope using forceps and scissors. Following results and conclusion were based on dissecting microscopic findings on 482 offsprings. 1. The eleventh day of gestation was the most sensitive day for nitrofen induction of congenital cardiovascular anomalies in the rat. This incidence was dose-related in rats exposed on the eleventh day of gestation. 2. Ventricular septal defect was the most common single anomaly that represented more than half of the total cardiovascular anomalies, followed by aortic arch anomalies and tetralogy of Fallot. 3. Cardiac anomalies derived from infundibular maldevelopment such as tetralogy of Fallot and pulmonary atresia with ventricular septal defect were only observed in the eleventh gestation day treated group. 4. Aortic arch anomalies were found in high frequency and the great majority were characteristically anomalous right subclavian artery with left aortic arch. Key words; nitrofen, congenital cardiovascular anomalies.

Between January 1984 and December 1986, sixty nine patients, aged 16 months to 25 years [mean age 10.05*6.40 years], underwent total correction of tetralogy of Fallot in Kyungpook national university hospital. In 66 hospital survivors, 30 patients were followed up for 12 to 48 months [mean 30.10*10.26 months]. These 30 patients were classified in two groups, TAP [transannular patch] and Non-TAP group. There were 9 patients in TAP group, and 21 in Non-TAP group. There were no significant differences between two groups in terms of age at operation, follow up duration, ACC time, and bypass time. All patients were evaluated by two dimensional echocardiography, Doppler echocardiography, standard 12-lead electrocardiography, and plain chest X-ray. Right ventricular systolic pressure, pulmonary arterial systolic pressure, pressure gradient between the right ventricle and the pulmonary artery, presence or absence of pulmonary regurgitation and its grading, fractional shortening of the left ventricle, and Qp/Qs in case of remnant ventricular septal defect were obtained by echocardiographic examination. Cardiothoracic ratio was measured by plain chest film, and ventricular dysrrhythmia was detected by electrocardiogram. Comparing the data between two groups, there was significant difference in incidence of postoperative pulmonary regurgitation [p< 0.05], 100%[9/9] in TAP group and 47.6 %[10/21] in Non-TAP group, but all the regurgitations were not severe. There were no significant differences in other comparisons, despite of higher incidence of cardiomegaly in TAP group [CT ratio: 59.3*5.3% VS 54.7*6, 4 %].

This report is concerned to our experience of 10 cases of open heart surgery under the extracorporeal circulation at the Department of Thoracic and Cardiovascular Surgery, Capital Armed Forces General Hospital during the period between May, 1982 and February, 1983. 1. Six cases were male and two cases were female. Age was varied from 21 years to 50 years and mean age was 34 years. 2. The cases included 2 Ventricular Septal Defects, 1 Atrial Septal Defect, I Tetralogy of Fallot and 6 acquired valvular heart diseases. 3. The surgical managements were 3 primary repairs for Ventricular Septal Defects and Atrial Septal Defect, I total correction for Tetralogy of Fallot and 6 mitral valve replacements with bovine xenograft by Ionescu-Shiley combining 3 Tricuspid annuloplasties [ De Vega method ] and 1 deauricularization of left atrial appendage for acquired valvular heart diseases. 4. The average cardiopulmonary bypass time was 37 minutes for acyanotic congenital heart diseases and 92 minutes for cyanotic heart disease and acquired valvular heart diseases. And the average aortic cross clamping time was 19 minutes for the former and 70 minutes for the latter. 5. Postoperatively, there were 1 hemolytic anemia, 1 congestive heart failure, 1 hemolytic jaundice and 1 thermal burn as complications, but there was no operative mortality. 6. All patients received valve replacement were recommended anticoagulation with Persantin and Aspirin.

In 1979 during the period of about 10 months 320 cases of open heart surgery were done in Seoul National University Hospital. There were 220 Congenital anomaly cases consisting of 113 acyanotic and 107 cyanotic varieties, and 1 O0 acquired cardiac lesions. Out of 100 acquired lesions 96 were valvular cues. Among 97 valve replacement cases 3 were Ebstein anomaly treated with plication and tricuspid valve replacement. Operative mortality rate for congenital anomaly was 10.6%, with 2.7% for acyanotic and 22.4% for cyanotic group. For acquired lesions over all operative mortality was 7%. Tetralogy of Fallot, ventricular septal defect, and atrial septal defect were the 3 main congenital anomalies, with 88 cues, 69 cases, and 27 cues respectively. In 61 simple ventricular septal defect without other anomalies operative mortality rate was 1.6%, in 27 atrial septal defect no death and, in tetralogy of Fallot 12.2%. Among 69 ventricular septal defect cases 19[27.5%] type I VSDs, after Kirklin-Becu classification, were found, rather high relative incidence of type I compared with Caucasian patients. Among 97 valve replacement cases 20 double valves were replaced-11 mitral with aortic and 9 mitral with tricuspid valves. Over all operative mortality rate for valve replacement was 8.2% with 3.3% in 61 mitral valve replace-merit. The over all operative mortality rate for 320 open heart surgery cases was 10.6%. Bubble type oxygenator and xenograft bioprosthetic valves were utilized In almost all cases.

The 67 patients who were operated as a tetralogy of Fallot during the period from 1985 to 1991 at the Department of Thoracic and Cardiovascular Surgery, Hanyang University were reviewed retrospectively. The age ranged from 3 month to 43 years old[mean 10.4 years old]. 39 patients were male and 25 patients were female. The body surface area ranged 0.4m2~1.6m2[mean 0.77m2] and body weight ranged 5.2kg~57kg[mean 20.2kg]. The 22 patients have history of previous shunt operation and average interval between shunt and total repair is 1.8years. The 43 patients were operated as primary total correction. The 53 patients were operated using transannular patch for right ventricular outflow reconstruction. And 12 patients were operated as right ventricular outflow recontruction only. Six patients were died postoperatively among 67 patients and with mortality rate of 8.7%. In patients group less than 0.7 of PRV/LV, there was no expired case but in patient group over than this level 3 patients were died among 14 patients. There were 6 death among the transanular patch group and no death in right ventricular outflow recontruction performed group. Postoperative complications were found in 9 cases including bleeding; 3 cases, residual VSD; 2 cases, wound infection: 2 cases, chylothorax 1 case and Lt. phrenic nerve palsy 1 case.
