A 8 year old male was admitted to the Department of Thoracic Surgery, Korea University Hospital on June 22, 1978. The chief complaints were cyanosis and exertional dyspnea since at birth. EKG shows BVH and dextrocardia, phonocardiogram revealed the accentuation of second heart sound in aortic area. Echocardiogram from the left ventricle to the base of the heart, there is a discontinuity between the ventricular septum and the anterior aortic margin with a large aortic root & aortic overriding. His cardiac catheterization data and cardiac angiogram shows situs inversus totalis, dextrocardia, right aortic arch, large ventricular septal defect etc., and finally diagnosed Truncus Arteriosus. Edwards type IV with retrograde aortogram and selective bronchial angiogram. This is the first operative case reported as Rastelli operation for Truncus Arteriosus type IV in the literatures in Korea. Authors have experienced I case of Truncus Arteriosus, Edward type IV and Rastelli operation with Dacron Arterial Conduit Graft under cardiopulmonary bypass on July 3, 1978. The procedures were as follows; 2] Cardiopulmonary bypass: Origin of bronchial arteries excised from descending aorta bilaterally; defects in aorta closed. 2] Horizontal incision made high in right ventricle. 2] Ventricular septal defect [Kirklin type I+II] closed with Teflon patch. 4] Bifurcated dacron arterial graft with pericardial monocusp sutured to the bilateral pulmonary arteries. [Diameter 9 mm: Length 7 cm]. 5] Proximal end of the conduit graft anastomosed to right ventricle. [Diameter 19 mm: Length 5 cm]..Total perfusion time was 220 min. The result of operation was poor due to anastomotic leakage and increased pulmonary vascular resistance resulting acute right heart failure. The patient was died on the operation table. Literatures were briefly reviewed.

Cardiac rhabdomyoma is a rare type of benign tumor affecting the heart. There are a few previous reports of intracardiac rhabdomyomas causing ventricular arrythmia. We describe a 1-year-old female tuberous sclerosis patient who was presented with a ventricular tachycardia. Diagnostic echocardiography revealed two masses in the left ventricular outflow tract originating from the ventricular septum. The masses were surgically resected through aortotomy using cardiopulmonary bypass and the masses appeared benign. The pathology was that of a cardiac rhabdomyomas. Postoperative course was uneventful and the ventricular tachycardia was controlled.

Traumatic ventricular septal defect (VSD) resulting from blunt chest injury is a very rare event. The mechanisms of traumatic VSD have been of little concern to dateuntil now, but two dominant theories have been described. In one, the rupture occurs due to acute compression of the heart; in the other, it is due to myocardial infarction of the septum. The clinical symptoms and timing of presentation are variable, so appropriate diagnosis can be difficult or delayed. Closure of traumatic VSD has been based on a combination of heart failure symptoms, hemodynamics, and defect size. Here, we present a case of a 4-year-old boy who presented with a traumatic VSD following a car accident. He showed normal cardiac structure at the time of injury, but after 8 days, his repeated echocardiography revealed a VSD. He was successfully treated by surgical closure of the VSD, and has been doing well up to the present. This report suggests that the clinician should pay great close attention to the patients injured by blunt chest trauma, keeping in mind the possibility of cardiac injury.

Myxomas are the most common form of intracardiac tumors and are found primarily in the left atrium. In rare cases, Carney and associates have described a syndrome called "the complex of myxoma" consisting of cardiac myxoma, which characteristically is familial, in assocation with two or more of the follow conditions: myxomatous masses (cardiac myxoma, cutaneous myxosma, and mammary myxoid fibroademoma), spotty pigmented lesions of the skin, and endocrine disorders. We report a case of familial atrial myxoma with Carney's complex in a 19-year old woman who has spotty pigmentations on her face, and left atrial myxomas, and myxoma on the right nipple. Her mother and sister share the left atrial myxoma. The myxomas originated in the septum of the left atrium and the anterior leaflet of the mitral valve were successfully excised. In conclusion, family members of affected patients should be screened periodically with echocardiography in an attempt to identify asymptomatic cardiac myxomas. Complete excision and postoperative follow up are necessary to rule out the muticentricity and high rate of recurrent lesions.

We have performed 27 cases of orthotopic homologous cardiac transplantation using Korean mongrel dogs and one case of sham operation for the evaluation of harmful effect of cardiopulmonary bypass itself on the dog from April, 1989 to June, 1990. Our previous reports have already demonstrated basal hemodynamic and hematologic data on the canine homologous heart transplantation and the fundamental principles of transplantation of the heart. The mean body weight of recipients was 13.2$\pm$1.2kg with a rage of 11 ~ 15kg, and the hemodynamic and hematologic pictures were almost same as the result of previous reports from our hospital, except marked decrease in postoperative platelet count[from 3.18 $\pm$0.80x106/mm3 to 1.41$\pm$0 37x 106/mm3]. Mean survival time was 24.82$\pm$49.40 hours with the longest survival of 264 hours. Donor cardiectomy included coronary vasodilatation with diltiazem, potassium arrest, and the rapid cooling of the heart suspending in the specially designed ice-bath. Median sternotomy provided excellent exposure of the surgical field. 6 \ulcorner0 prolene suture was used for the anastomosis of both atrial cuffs and the great arteries, and we found the fact that stenosis, bleeding, thrombus formation around the anastomotic site could be decreased with the use of everted horizontal mattress suture techniques. Immunosuppression was done with a combination of lower dose Cyclosporin-A, Azathioprine, methyl-prednisolone, but our cases still showed too short survival to worry about graft rejection. Still poor was our quality control of experimental animal, we had much difficulties in postmortem evaluation of the dogs. Low cardiac output due to biventricular failure, intractable supraventricular or ventricular tachyarrhythmia, postoperative massive bleeding, sepsis were most frequent findings that could be thought as a cause of death. A few cases showed subendocardial patch hemorrhage in both ventricular cavity or atrial septum at autopsy, suggesting acute subendocardial infarction. Although our team overcome most of the technical problems of orthotopic heart transplantation, we should pile up further knowledges about donor heart preservation, quality control of animal, infection, rejection, the effect of the cardiopulmonary bypass to improve the results.

Eighteen patients (13 female and ave male) aged from 15 to 62 years (mean age 42.6 years) underwent excision of cardiac myxoma(17 left atrial, one right atrial) between 1985 and 1994 at Pusan National University hospital. All patients complained of exertional dyspnea and most had a few additional symtoms including palpitation, chest pain, syncope, general weakness, weight loss, fever, cough and epigastric disconyort. The diagnosis was made by echocardiography alone in left atrial myxomas but a myxoma in right atrium was diagnosed incidentally during mitral valve replacement for rheumatic valvular heart disease. The tumor attachment sites were fossa ovalis in 13, other interatrial septum in 4, mitral valve annulus in one and free wall of left atrium in two cases. The tumor was excised successfully via right atriotomy in 8 and biatriotomy in 10 cases. There was no hospital nor late death, and no recurrent case during the follow up period. Curative surgical excision of cardiac myxoma can be performed with low morbidity and very low r currence rate.

Decreased exercise capacity after Fontan surgery is relatively common and the failure of the Fontan state gradually increases with age. However, there is no further treatment for patients with Fontan circulation. Pulmonary vasodilation therapy is an effective method to solve this problem because pulmonary vascular resistance is a major factor of the Fontan problem. Inhaled iloprost is a chemically stable prostacyclin analogue and a potent pulmonary vasodilator. We experienced two cases of Fontan patients treated with inhaled iloprost for 12 weeks. The first patient was an 18-year-old female with pulmonary atresia with an intact ventricular septum, and the second patient was a 22-year-old male with a double outlet right ventricle. Fifteen years have passed since both patients received Fontan surgery. While the pulmonary pressure was not decreased significantly, improved exercise capacity and cardiac output were observed without any major side effects in both patients. The iloprost inhalation therapy was well tolerated and effective for the symptomatic treatment of Fontan patients.

Myxoma is a benign growth constituting nearly 50% of all primary cardiac tumors. It is important because it can be abolished by surgical therapy and is usually fatal if unrecognized and untreated. Recently a wider use of echocardiogram as the screening test of valve lesions can be expected to increase the number of myxomas found preoperatively. We report a case of left atrial myxoma which was diagnosed by echocardiogram before surgery, and was successfully removed with the aid of extracorporeal circulation. The patient was a 24-year old woman who had suffered from mitral valvular symptoms for 2 months before admission. At operation, a tumor, measuring 5.2 x 4.3 x 4.7 cm, was extremely friable, villous gelatinous mass and it was removed from its origin near the closed fossa ovalis, including its stalk and a portion of the septum. The postoperative course was uneventful. The patient is clinically well and without symptoms of heart disease.

The syndrome of anomalous muscle bundle dividing the right ventricle into two pressure chambers has been described by many authors. The malformation should not be confused with tetralogy of Fallot itself because the obstructive hypertrophic bands are usually proximal to the right ventricular infundibulum. One case [11 years old male] of double chambered right ventricle due to aberrant muscle bundle with intact ventricular septum is presented. The pressure gradient was 68 mmHg between inflow and outflow tracts of right ventricle on cardiac catheterization. On opening the right ventricle, there noted stenosis of outflow tract by infundibular membrane, hypertrophied anomalous muscle bundle, thickened moderator band & hypertrophied anterior papillary muscle. Open heart surgery was carried out with the aid of extracorporeal support, Anomalous muscle bundle [1.0 cm x 4.0 cm] and infundibular membrane were resected safely. The hypertrophied moderator band was cut at mid-portion and anterior papillary muscle was split vertically. The postoperative course was uneventful and discharged in good condition 2 weeks later.
