The criss-cross, a term first used by Anderson and Ando , is a rare cardiac malformation in which the systemic and pulmonary blood streams cross at the atrioventricular level, without mixing. We have surgically experienced four cases of crossed atrioventricular connection, three concordant and one discordant, at Seoul National University Hospital from July 1982 to March 1984. The atrial situs, the atrioventriculoarterial connection, the spatial position of the ventricles, and associated cardiac anomalies were analyzed. We have performed right Blalock-Taussig shunt for case 1, modified Fontan operation for case 2, patch closure of VSD for case 3, and septation of common ventricle with primary closure of ASD for case 4. The relatively good postoperative results in these patients were gratifying and suggest that cardiac anomalies associated with this rare malformation can be successfully repaired without further risk. To our knowledge, this is the first report of surgical experience for criss-cross heart in the Korean literature.

Aorto-ventricular tunnel is a rare congenital malformation, and aorto-right ventricular tunnel (ARVT) is an even less common entity. Here, we report the case of a 3-month-old female who underwent successful surgical closure of ARVT. The origin of the right coronary artery was proximal to the ostium of the tunnel.

목 적 : 계태의 발생 과정에서 감마선 조사에 의한 심장 기형유발 유무와 심장 기형의 종류를 알아보기 위하여 본 연구를 시행하였다. 방 법 : 토종 닭의 수정란을 사서 닦은 후 대조군에게는 감마선을 조사하지 않았다. 실험군으로 닭의 수정란을 인공 부화기에 넣고 3일 후(72시간 후)에 꺼내어 700 curie 1.25 Mev Cobalt 60에서 나오는 감마선을 50 rad, 100 rad, 150 rad, 200 rad, 250 rad, 300 rad로 각각 60개의 수정란에 조사 후 인공 부화기에 넣어 총 3주간 지속시켰다. 온도 $38^{\circ}C$와 습도 55-70%로 유지하여 3주간 부화시킨 계태를 개흉하여 포르말린으로 고정하였고, 실물 현미경하에 해부하였다. 결 과 : 감마선 조사하지 않은 대조군에서 생존율은 76.4%이었고, 심장 기형은 발견되지 않았다. 실험군에서는 50 rad에서 300 rad로 선량이 강할수록 생존율은 63.3%에서 33.3%로 유의하게 감소하였고(P<0.001), 심장 기형의 발생률도 생존 계태의 7.8%에서 25.0%로 유의하게 증가하였다(P<0.001). 선량이 증가 할수록 심실중격결손의 크기가 증가하고 복잡기형이 나타나는 경향을 보였다(P<0.001). 대혈관 기형도 이상기시, 저형성, 형성부전으로 심해지는 경향을 보였다. 결 론 : 계태 발생 과정 중 감마선 조사의 시기와 선량이 선천성 심장병의 발생에 중요한 영향을 미친다. 조사 시기를 3일 후로 고정한 후 선량이 증가함에 따라 생존율은 감소하였으며, 선천성 심장병의 빈도는 증가하였고, 복잡 심장 기형이 생겼다. 또한 감마선 조사에 의해서 계태에서 혈관 기형을 유발할 수 있었다. 감마선 조사는 계태에 직접적인 조작을 하지 않고 또한 혈역학적 변화를 직접 유도하지 않는 실험이므로 거대분자인 핵산의 변화에 의해서 심장 기형과 대혈관 기형이 발생하였을 것으로 생각하며 기형 형성의 기전을 밝히기 위해 앞으로 염색체와 분자유전학적 연구가 필요할 것이다.

A 17-month-old intact male Cocker Spaniel was presented with primary complaints of severe ascites, exercise intolerance, and diarrhea. Diagnostic studies revealed tricuspid and pulmonic regurgitation on phonocardiogram, right ventricular enlargement on the electrocardiogram, typical right cardiac enlargement signs on the thoracic radiography and tricuspid valve malformation and marked enlargement of the right atrium and right ventricle on the echocardiography and tricuspid and pulmonary regurgitation on the color spectral echocardiography, suggesting tricuspid valve dysplasia and pulmonary hypertension. Using angiography and cardiac catheterization, pulmonary hypertension was ruled out. Further echocardiographic study revealed membranous valvular structures cranial to pulmonary annulus causing pulmonary regurgitation. Based on these findings on the diagnostic investigation, the case was diagnosed as tricuspid valve dysplasia complicated with pulmonic regurgitation. The dog was medically managed with furosemide, enalapril, nitroglycerine transdermal patch and pimobendan after the ascitic fluid removal.

Native valve endocarditis (NVE) without preexisting structural valve or congenital cardiac malformation especially in pediatric group is rare. A case of isolated tricuspid valve endocarditis in a 7-year-old child without any cardiac malformation is described. This child had suffered from fever and productive cough for 3 weeks. Blood culture grew Staphylococcus aureus. Fever was not controlled even with proper antibiotic treatment. Transthoracic echocardiogram and lung perfusion scan revealed a large vegetation on the tricuspid valve with multiple embolism Surgical procedures included vegetectomy partial cusps resection and pericardial patch valvuloplasty. Th patient was in NYHA class I during follow up.

Fourteen Infants with congenital cardiac anomalies underwent primary surgical Intervention within the first 12 months of life. There were eight patients with ventricular septal defect, two with total anomalous pulmonary venous return [TAPVR], and the remainders with tetralogy of Fallot, transposition of great arteries [d-TGA], Taussing-Bing malformation, and coronary A-V fistula. The age of the patients ranged from 5 to 12 months, with a mean age of 9.9 months. The mean weight was 6.7 Kg [3.8 to 9.5 KS]. Congestive heart failure persisting despite intensive medical treatment was present In 8 patients [56%], and was the most common indication for operation. Early operation was necessary in 5 of these patients [35%], because of failure to thrive and recurrent pulmonary infection. In one patient with TOF, frequent hypoxic spell prompted the necessity for early operation. In cases of VSD, TAP. VR, TOF, and coronary A-V fistula, Intracardiac repair was done with conventional cardiopulmonary bypass, chemical cold cardioplegia, and topical myocardial cooling. Deep hypothermic circulatory arrest with surface induced cooling, followed by core cooling and core rewarming, was employed .for better exposure in the cases of d-TGA and Taussing-Bing malformation. The results were however, not satisfactory. The overall mortality was 28 per cent. There were no deaths in the eight patients with VSD. The one with coronary A-V fistula survived. The other 5 cases all expired either on the table or immediately after operation. The non-fatal post-operative complications included low cardiac output, respiratory insufficiency, bleeding, and temporary A-V block. The causes of death were prolonged circulatory arrest time in d-TGA, complete A-V block and low cardiac output in TOF and Taussing-Bing malformation and prolonged bypass time and Inadequate correction in TAPVR.

A case of a 7 year old girl with rare congenital anomalies is reported. The anomalies as called Cantrell`s pentalogy is consisted of defect in supraumbilical abdominal wall, ventral diaphragm, adjacent pericardium, and lower sternum associated with cardiac malformation. Her cardiac lesion was muscular diverticulum of left ventricle. The diverticulum was resected and the other defects were repaired successfully.

Tetralogy of Fallot with absent pulmonic valve is a rare cardiac malformation. The most significant symptoms during early infancy are secondary to bronchial compression resulting from the dilated pulmonary arteries. The clinical diagnosis was confirmed by echocardiography, cardiac catheterization and cardioangiography. A case of TOF with absent pulmonic valve was successful operated upon without insertion of the pulmonic valve. The narrow pulmonic valve annulus was enlarged with a transannular pericardial patch graft. The postoperative course was uneventful.

Since Krause first described coronary arteriovenous fistula in 1865, there have been nearly 300 additional patients with this malformation reported in the literature. Increasing numbers of patients with this anomaly are being recognized each year resulting from the widespread use of cardiac catheterization and selective coronary arteriography in the evaluation of a variety of cardiac problems. A 9 month old male was admitted with the chief complaint of cardiac murmur and frequent URI and diagnosed as coronary A-V fistula at the distal portion of left anterior descending coronary artery to the apex of the right ventricle by cardiac catheterization and aortography. On the operative field, the left anterior descending coronary was markedly dilated about 1.5 cm in diameter from the aorta to the apex of the heart. The fistula opening was closed with 5-0 Prolene continuously under cardiopulmonary bypass and moderate hypothermia[28*C]. Postoperative course was uneventful and the patient was discharged without problem.
