An approximately 8-month-old, 2.61 kg, male Siamese kitten was referred with primary complaints of a 1-week history of respiratory distress, exercise intolerance and dyspnea. Diagnostic studies identified III/VI systolic murmur in the cardiac auscultation, right ventricular enlargement patterns in the electrocardiogram, pleural effusion and right-sided cardiomegaly in the thoracic radiography, and right marked ventricular dilatation, right atrial enlargement, atrial septal defect and abnormal left atrium divided by fibromuscular membrane. Based on these findings, the case was diagnosed as cor triatriatum sinistrum complicated with an ostium primum atrial septal defect. The cat was rescued with furosemide, nitroglycerine, oxygen supplement and fluid removal from pleural cavity.

Atrial septal defect is one of the most frequently encountered congenital heart disease. Up to December 31, 1976, 1682 cardiac patients received cardiac catheterization in the cardiac department of Yonsei university medical college. Out of the 1682 cardiac patients 723 cases had congenital heart disease and only 116 cases had congetial atrial septal defect. This amounted to 16.04% of all those with congenital heart disease. 58 cases of congenital atrial septal defect operated in the chest surgery department were presented. Of these 58 cases of atrial septal defect, 27 cases were male and 31 cases were female. Their ages ranged from 5 years to 54 years. The systolic pressure of the main pulmonary artery of 40 out of the 58 cases of atrial septal defect was below 40% of that of the systemic blood pressure: in 6 cases, the range of the systolic pressure of the main pulmonary artery was 50-90mmHg; in 12 cases, the range of the systolic pressure of the main pulmonary artery was 40-50mmHg. Average age of these was 30. 1 years. This study tends to show that Korean patients with atrial septal defect even though younger have a slight higher systolic pressure of the main pulmonary artery than Western patients have. The pulmonary blood is 1.5-2.5 times of systemic blood flow in 52 cases out of 58 cases of atrial septal defect.In only one of the 58 cases of atrial septal defect, the Rp was found to be as high as 45% of Rs. All other cases were below this level.51 cases had ostium secundum defect, 4 out of these cases had ostium secundum defect combined with mitral incompetence and 6 out of them had double ostium secundum defect. The remaining 7 cases had ostium primum defect. Their atrial defects were repaired under direct vision utilizing extracorporeal circulation, by hemodilution technic combined with moderate hypothermia. 44 cases [2nd atrial septal defect] were repaired by direct sutures while 14 cases, including the 7 cases ostium primum defects needed patches [1 pericardium and 13 teflon patch]. In 4 cases there were single defects while showed two defects. However the associated septal defect was so small that it could be closed by direct sutures. The size of the defect ranged between 6.0cm2and 10.0cm2 in 19 cases[33.7%]: the smallest being 0. 5cm2 and the largest 24cm2. The surgical mortality was 2 cases [3.4%]. These one case with ostium primum defect, could not be resuscitated on operation table. The cause of death in this case was myocardial failure and MI. The other, a case of ostium primum defect had a second operation on the first operative day due to massive bleeding from LV vent-line insertion site.The patient died on 26th post-operative day due to sepsis.

Thirteen patients underwent repair of atrioventricular septal defect [AVSD] from January 1980 to July 1989 at Kyungpook National University Hospital. Two patients had complete AVSD [Rastelli type A] and eleven patients had partial AVSD [ostium primum atrial septal defect and cleft of anterior mitral leaflet]. In all the patients of partial AVSD, atrial septal defect was closed with Dacron patch and the mitral cleft was approximated with interrupted simple sutures. In one patient of complete AVSD, one patch technique was used to close the atrial and ventricular septal defect, and in the other patient of complete AVSD, two patch technique was used. In six patients, there were associated anomalies; four had isolated ostium secundum ASD, two had patent foramen ovale. Postoperative complete A-V block was noted in a patient of partial AVSD, but it was returned to 1st degree A-V block 30 months later and in another case of partial AVSD, severe congestive heart failure [NYHA functional class IV] due to residual mitral insufficiency was developed postoperatively, but this patient was recovered to the state of functional class I after receiving mitral valve replacement. There was one hospital death [8 %] resulting from low cardiac output.

A 2-year-old female Maltese dog was referred with primary complaints of exercise intolerance and abnormal heart sound. Clinical and diagnostic investigation revealed split S2 and S4 gallop in the cardiac auscultation, tall P wave and left anterior fascicular block in the electrocardiogram, left atrial enlargement on the thoracic radiography, ostium primum atrial septal defect and cleft of the anterior leaflet of the mitral valve on the echocardiography. Based on those findings, the dog was diagnosed as the partial atrioventricular canal defect. Since the dog showed mild exercise intolerance, enalapril and furosemide were prescribed.

The partial A-V canal defect consist of ostium primum type atrial septal defect with a cleft mitral anterior leaflet. The clinical findings depend upon the site and size of the left-to-right shunt, the degree of A-V valvular regurgitation, and the degree of resultant pulmonary artery hypertension. We experienced 3 cases of similar condition. The data were as follow: 1. Chest P-A showed increased pulmonary vascularity and moderate cardiomegaly with left atrial enlargement. 2. E.K.G. showed left axis deviation, left atrial enlargement, and left ventricular hypertrophy. 3. Right heart catheterization showed significant 02 step up of SVC-RA and left-to-right shunt. 4. Left ventriculogram showed mitral regurgitation and filling of both atrium. Operative findings were as follow: 1. Primum type atrial septal defect [2x2 cm]. 2. Cleft in the anterior leaflet of the mitral vave. 3. No evidence of ventricular septal defect and tricuspid anomaly. Through a right atriotomy with moderate hypothermia, the mitral cleft was approximated with interrupted sutures. The interatrial communication was closed by a patch of Dacron/pericardium. The patch was attached to junction of the mitral and tricuspid valves along the crest of the ventricular septum using interrupted sutures and the other site using continuous sutures. Postoperative course was uneventful and discharged in good general condition except postoperative bleeding in case 3.

Fifty seven patients underwent repair of a partial atrioventricular septal defect from January 1980 to December 1986. The ostium primum atrial septal defect was closed with autologous or bovine pericardium. The cleft in the anterior mitral leaflet was present in 53 cases, absent in 4 cases. Of the 53 cases with a cleft in the anterior mitral leaflet, 48 received suture repair of the cleft, 3 received mitral valve replacement. There was no hospital death and all the patients were followed-up for a mean period of 26.4 months. Four required permanent pacemaker implantation due to complete heart block, and one of them died of sudden malfunction of pacemaker. Two received reoperation due to significant residual mitral insufficiency. Suture repair of the cleft in the anterior mitral leaflet resulted in significant decrease in degree of mitral regurgitation. During follow-up period 49 patients were in NYHA class I, 7 patients were in NYHA class II. This report suggests that excellent result can be achieved from repair of the partial atrioventricular septal defect by managing the left A-V valve as a bileaflet structure.

23례의 환자에서 1989년 12월부터 1996년 12월까지 우전측방흉부절개술(RALT; right anterolateral thorncotomy)을 이용하여 선천성 심장병을 수술하였다. 22례에서 심방중격결손증(단순난원공형 13례, 하대정맥부 위로 확대된 저위형 쩨, 후방확대형 쎄, 정맥동형 1례, 일차공형 떼)이었고, 떼에서 심실중격결손증이었다. 우전측방흉부절개술(RALI)과 관련된 수술중 사망률이나 후기이환율은 없었다. 우전측방흉부절개술(RALI)은 선택된 환자에서(특히 여자) 정중흉골절개술에 비해 안전하고 효과적인 방법으로 생각되며, 추적관찰시 미용의 측면에서 결과는 매우 좋았다.

부분 심내막상 결손증은 일차공 결손과 승모판 전엽에 열공을 동반하는 질환으로 완전형 심내막상 결손증에 비해 임상 증상이 심하지 않으나, 승모판 부전이 진행할수록 심비대, 심부전, 폐동맥 고혈압 등이 더욱 쉽게 발현되어 그 예후가 좋지 않고, 따라서 고령에서는 보기 힘든 질환이다. 본원으로 30년 전부터 증상이 있던 67세 부분 심내막상 결손증 환자가 내원하였다. 심도자 검사상 폐동맥압이 45/22 mmHg, 평균 압력은 32 mmHg로 약간의 폐동맥 고혈압이 있었고, 수술 소견상 $3.5{\times}2.5\;cm$ 크기의 일차공 결손과 심한 석회화를 동반한 승모판 전엽의 열공이 보여 일차공 결손 첨포 봉합과 승모판막 치환술을 시행하였다. 수술 후 11일째부터 심한 방설 차단이 발생하여, 영구 심박동기를 삽입하였고, 수술 27일 후 퇴원하였다. 저자들은 임상적으로 보기 드문 고령에서의 부분 심내막상 결손증을 수술적으로 교정하였기에 문헌 고찰과 함께 보고하는 바이다.
