Congenital coronary arteriovenous fistula is relatively uncommon and often associated with additional congenital and acquired heart disease. If coronary arteriovenous fistula is suspected, the diagnosis can be made readily by cardiac catheterization and selective coronary arteriography. Surgical treatment is very satisfactory, with a low mortality and apparent good long term result. Recently, we experienced one case of congenital coronary arteriovenous fistula which was associated with aortic stenosis and regurgitation. The tortuous fistula tract was noted between the left anterior descending coronary artery and the main pulmonary artery. Under the cardiopulmonary bypass, aortic valve replacement[Carbomedics 23mm] and suture closure of the draining orifice of coronary arteriovenous fistula in the main pulmonary artery just above the pulmonary valve were performed, Postoperative hospital course was uneventful and the patient was discharged postoperative 9th day without any problems.

Cor triatriatum is a rare congenital malformation of the heart in which a diaphragm stretches in a transverse plane through the left pulmonary venous chamber, thus creates two subchambers. The proximal chamber connects with the pulmonary veins, and the distal one has left auricle and the mitral valve. A 3 year old boy who had Cor triatriatum underwent surgical excision of the abnormal diaphragm in March, 1989 in Chungnam University Hospital. An obliquely oriented fibromuscular diaphragm divided the left atrium into a proximal chamber which was connected to the pulmonary veins and a distal chamber which had the atrial appendage and the mitral valve. The opening in the diaphragm was 5 mm in diameter. There were no associated abnormalities. The abnormal diaphragm was completely excised. The postoperative result was excellent.

Truncus arteriosus is one of the rare cyanotic congenital cardiac anomalies and thought to be result from complete or partial failure of trunco-conal septum. A single arterial trunk receiving blood from both ventricles supplies the coronary, pulmonary and systemic circulation. The symptoms were usually related to the degree of the pulmonary blood flow and functional status of truncal valve, and mostly appeared within the first two months of life. The prognosis is generally considered to be poor in spite of successful surgical correction. This report is a case of 13 years old female with type I truncus arteriosus, which was successfully corrected using a intracardiac Dacron tunnel graft[semilunar, 18mm] from VSD to the truncal valve, and a extra-cardiac lonescu-Shiley valved[20mm] Dacron conduit [21mm] from RV to the pulmonary artery[Rastelli operation].

In small children with left ventricular outflow tract obstruction, a few methods of surgical treatment could be considrred. The pulmonary autogrart provides a promising options for aortic valve replacement as part of the aortoventriculoplasty procedure in children. We report a successfully treated congenital aortic stcnoinsufricicncy with severe left ventricular dysfunction in an early infant with the aortoventriculoplasty using thc pulmonary autograft (the Ross-Konno procedure).

Prolapse of the aortic valve is the main cause of insufficiency of the aortic valve as a complication of ventricular septal defect. Aortic insufficiency gets worse by the progress of prolapse of aortic valve due to lack of support of the valve and the hemodynamic effect of blood flow through the ventricular septal defect. This produces typical clinical picture, that may be serious and threatening when it is untreated. Type and timing for the surgical treatment of the ventricular septal defect with aortic insufficiency is considered. Among 113 ventricular septal defect, 9 patients of ventricular septal defect with associated aortic insufficiency were experienced from June. 1983 to June 1988 at the Department of Thoracic and Cardiovascular Surgery, Chon-Buk University Hospital. Male was 6 patients and female was 3 patients. Ages were from 7 years to 24years. 5 patients were from 10 to 19 years age. 3 patients were below 10 years age. The ratio of pulmonary blood flow to systemic f low [Qp/Qs] was 1.53 and in pulmonary vascular resistance, normal or slight increase was 7 patients, moderate 1 patient, and severe 1 patient. Ventricular septal defect was subpulmonic in 5 patients and infracristal in 4 patients. Prolapse of right coronary cusp was 7 patients, right and non coronary cusp 1 patient and non coronary cusp 1 patient. Teflon patch closure of ventricular septal defect was undertaken in 3 patients and primary closure in 1 patient. Among the 4 patients of defect closure alone, one patient performed valve replacement 7 months later due to progressive regurgitation and cardiac failure and the result was good. The other 3 patients were good result. Closure of ventricular septal defect and aortic valvuloplasty performed in 4 patients. 2 patients of these required valve replacement for the sudden intractable cardiac failure and died due to low cardiac output. The cause of intractable cardiac failure was tearing of repaired valve at the fixed site. The other 2 patients were good result. Closure of ventricular septal defect and valve replacement performed in 1 patient with good result.

Between Jan. 1986 and Aug. 1992. 72 patients underwent Rastelli procedure. There were 43 male and 29 female, aged 46 days to 16 years [mean age, 5.2 years] with 18 patients less than 2 years of age. All patients had complex defect, 27 pulmonary atresia with ventricular septal defect, 18 corrected transposition of great arteries with pulmonary atresia or punmonary stenosis, 10 truncus arteriosus, 10 double outlet right ventricle with pulmonary atresia or stenosis, 7 complete transposition of great artersia with pulmonary atresia or pulmonary stenosis. The types of extracardiac valved conduit used were prosthetic valve[n=47, 24 car-bomedics, 19 Ionescu-Shiley, 4 Bjork-shiley] and hand-made trileaflet valve using pericardium. [n=23, 20 bovine pericardium, Z autologous pericardium, 1 equine pericardium] The mean size of valved cinduit was 5.25mm larger in diameter than the size of main pulmonary artery. [normalized to the patient`s body surface area] There were 17 hospital death[24%] and 4 late deaths[5.6%]. Postoperative complication rate was 38.9%a, none of which was conduit-related. All patients were followed pos-toperatively for 1 to 73 months. [mean 25.8 months] During follow-up period, reoperation was done in 6 patients due to stenosis of valved conduit. Mean interval between intial repair and reoperation was 20.3 months. In our experience, li recently extracardaic valved conduits between right ventricle [or pulmonary ventricle] and pulmonary artery were inserted with increasing frequency in infants less than 2 year, but hospital mortality was decreased, 2] Risk of reoperation due to conduit stenosis is low, so that the effect of graft failure on overall survival is minimized. 3] Nevertheless, because any type of extracardaic valved conduit is not ideal in children, we recommended that Lecompte should be done if cardiac anatomy is permitted.

Since January 1977 to the end of September 1982, total 60 Ionescu-Shiley pericardial xenograft heart valves were implanted for valve replacement in 50 patients at the Han Yang University Hospital. The operative procedures were as follow: Mitral valve replacement [MVR] in 25 patients, Mitral valve replacement [MVR] and Tricuspid valve [TV] annuloplasty in 7 patients, Aortic valve replacement [AVR] in 8 patients, Aortic valve replacement [AVR] and Mitral valve replacement [MVR] in 8 patients. Aortic valve replacement [AVR] and Mitral valve replacement [MVR] and Tricuspid valve [TV] annuloplasty in 2 patients. To evaluate the immediate hemodynamic changes after valve replacements, the pressures of each cardiac chamber and ulmonary artery were checked before and after valve replacement on the operation table. Right ventricle [RV] pressure was decreased from 52.09\ulcorner6.71 to 45.57\ulcorner5.03 mmHg, Pulmonary artery [PA] pressure was decreased from 45.97\ulcorner2.69 to 41.00\ulcorner3.99 mmHg, and Left atrium [LA] pressure was decreased from 30.33\ulcorner13.02 to 22.76\ulcorner.97 mmHg before and after valve replacement. In MVR group, RV pressure was decreased from 49.17\ulcorner7.89 to 43.14\ulcorner4.14 mmHg, PA pressure was decreased from 44.67\ulcorner3.18 to 38.67\ulcorner2.85 mmHg, and LA pressure was decreased from 31.46\ulcorner13.47 to 21.91\ulcorner.17 mmHg. In AVR group, RV pressure was decreased from 53.0\ulcorner7.44 to 44.71 \ulcorner3.24 mmHg, PA pressure was decreased from 34.83\ulcorner0.73 to 31.86\ulcorner.36 mmHg, and LA pressure was not changed. In double valve replacement [MVR and AVR] group, RV pressure was decreased from 57.50\ulcorner3.82 to 42.50\ulcorner.80 mmHg, PA pressure was decreased from 51.17\ulcorner1.42 to 43.33\ulcorner4.53mmHig, and LA pressure was decreased from 34.33\ulcorner2.09 to 25.50\ulcorner0.21 mmHg. But in the group where MVR and TV annuloplasty were performed, preoperative RV and PA pressure were markedly increased and no pressure decrease in RV and PA noticed after valve replacement. This study shows good immediate postoperative hemodynamic results after valve replacement using Ionescu-Shiley xenograft valve except in the cases of MVR and TV annuloplasty and advanced disease with pulmonary hypertension.

Cardiac surgery in patients with a prior pneumonectomy has a high prevalence of postoperative complications and mortality. We have successfully performed a mitral valve replacement and tricuspid annuloplasty in a 71-year-old man who had a left pneumonectomy 33 years previously due to pulmonary tuberculosis. We report this case with a literature review on the issue of the prevention perioperative pulmonary impairment, the technique of mitral valve exposure during surgery and postoperative rhythm disturbance.

Between April 1976 and March 1978, six cases of tricuspid valve replacement were done in the Department of Thoracic Surgery, Seoul National University Hospital. There were 4 men and 2 women and the age of the patients ranged from 17 years of the youngest to 48 years of the oldest. Most of them had characteristic symptoms of tricuspid valve disease, such as a systolic murmur audible over the lower sternum and varying with respiration, pulsatile and distended neck vein, and an enlarged and pulsatile liver. Preoperative functional levels according to NYHA Calcification were class III in 4 cases, and class IV in 2 eases. Most of the cases showed moderate to severe cardiomegaly in chest films and elevated right atrial pressure on preoperative right heart catheterization. Five of them underwent concomittent mitral valve replacement and one pulmonary valvotomy. All of them showed tricuspid insufficiency resulted from massive dilatation of annulus, destructive lesions of valve structure, or both anomalies. One postoperative hospital death was encountered and the cause of death was low out-put syndrome. All survivors showed clinical improvement and cardiomegaly regressed and left hospital in a good condition . *Attendum; Recently 2 more cases of tricuspid valve replacement with mitral valve replacement were done after this review.
