Subaortic stenosis in a 2.9kg, 3-month-old pug dog and a 11 kg, 4-month-old Rott -weiler dog showing signs of dyspnea, tachypnea, anorexia, exercise intolerance and depression was diagnosed with electrocardiography, thoracic radiography and ultrasonographic evaluation. In electrocardiography, PR interval widening, R wave amplitude increase in lead II in case 2, ST segment depression and left axis deviation in case 1 and 2 were identified. In thoracic radiographs, enlarged left ventricle and atrium, caudal displacement of left crus of diaphragm and caudal part of cranial mediastinum widening were identified in ventrodorsal view. In lateral view, left ventricular enlargement, secondary dorsal deviation of trachea and post-stenotic dilation of aorta were seen. Also, edematous pulmonary changes were shown in peri-hilar area. In ultrasonographic examination, left ventricular dilatation, pericardial effusion and subaortic valvular ridge were seen with real time B-mode in right parasternal long axis view. Aortic valve regurgitation was identified in color-Doppler mode.

A seven month old female infant with isolated ventricular inversion and anatomically corrected malposition of the great arteries in situs solitus, associated with ventricular septal defect, patent ductus arteriosus, right-sided juxtaposition of left atrial appendage, is reported. The patient showed usual atrial arrangement with somewhat superoinferior relation, a discordant atrioventricular connection, and a concordant ventriculoarterial connection with aorta in the right-sided position. A normal sized left atrium was connected to the left superiorly positioned morphologic right ventricle through a tricuspid valve, which crossed the left ventricular outflow tract anteriorly. Well developed bilateral[subaortic and sub-pulmonary]conus was documented at operative field. successful surgical repair was done by performing the Senning procedure and by closing the ventricular sepal defect with a patch through the right ventriculotomy. The infant’s postoperative course was uneventful with normal sinus rhythm. Postoperative cardiac catheterization revealed no hemodynamic obstruction or residual shunt.

Lymphangiohemangiomas of the mediastinum are exceedingly rare and few cases have been published in the English literature. This report may be the only reported case in which lymphangiohemangiomas were found bilaterally. We report a case of a 7-year-old boy with an incidental finding of an abnormal mediastinal shadow on a chest X-ray. The chest CT showed a large mass in the left superior mediastinum and another in the right posterior mediastinum. The left mass had anomalous venous channels connected to the left innominate vein, and the right mass to the left atrium. We performed an excision of the mass in the left side first and then the right side one month later. Anomalous venous channels were dissected carefully and ligated. There were no complications and no signs of recurrence 30 months after the operation.

우심실 형성부전이 있으면서 단신방, 그리고 스펀지 좌심실이 있는 매우 드문 질환인 독립된 우심실 형성부전 환아를 경험하였다. 수술 전 우심실의 크기는 좌심실의 반이었으며 삼첨판막의 크기는 z-value로 -4이었다. 수술 시 6세였으며 수술은 양심실성 교정을 시도하여 심방을 2개로 나누어주었으며 3mm 구멍을 남겨 두었다. 수술 후 경과는 좋았으며 외래 추적에서 우심실 기능 부전소견은 없었다. 술 후 27개월에 심도자가 시행되었으며 삼참판막은 잘 자랐으며(z-value=-0.4), 심방중격의 구멍은 저절로 막혔음을 확인하였다. 독립된 우심실 형성부전을 경험하여 성공적으로 양심실성 교정을 시행하였기에 보고하는 바이다.

Unknown age, spayed female mixed dog was presented with a severe lethargy. Radiography, ultrasonography, and blood screen test were performed to make a diagnosis. There were no specific radiographic findings. On the ultrasonography, small amount of ascites was found around gallbladder and hepatic vein was dilated approximately 6.1 mm. Blood screen test revealed a severe anemia. Result of heartworm ELISA kit was positive. At necropsy, parasites were in the left atrium, right ventricles, aorta, pulmonary artery, right renal artery.

Fifteen patients[10 female and 5 male from 13 to 73 years of age[mean age 46 years underwent excision of atrial myxomas between 1981 and 1993 at the Chonnam University Hospital. Fourteen patients presented with exertional or resting dyspnea, six with palpitation, five with systemic embolization, and three with syncope. Symptoms were present from 1 week to 14 months before operation. Fourteen tumors originated from the atrial septum of left atrium and one of bilateral atrium. All tumors were pedunculated; tumor sizes were variable from 2x1x1cm to 7x6x5cm. No ventricular tumors identified. The myxomas were successfully removed in all patients, either by shaving them from the atrial septum[n=7 or excising a portion of normal atrial septum with the tumor and ASD patch closure[n=8 . There was no perioperative or late death in our experience. Follow-up is current and complete in all cases[range 6 months to 13 years . Thirteen patients are in New York Heart Association Class I, and the remaining two patients are in Class II. One recurrent left atrial myxoma was identified at 20 months after operation. In this series, excellent results were obtained by simple excision of the tumor, with or without a margin of normal atrial septum. Long-term clinical & echocardiographic follow-up is recommended since late recurrence, although rare, has been reported.

From Jan. 1981 to Dec. 1991, we had treated 25 patients with congenital coronary art-eriovenous fistulas [CAVF] in Seoul National University Hospital. A retrospective review was made to delineate the course and the management of CAVF and to clarify the role of surgical treatment. Fifteen patients were male and 10 were female with The mean age of 17.4 years[from 3 months to 58 years]. The most frequent symptom was dyspnea on exertion[56%]. Other symptoms were angina and palpitation. Sixty-eight percent of the patients were symptomatic. Fifty-three percent of patients less than 20 years old were symptomatic and 100% of patients over 20 years old were symptomatic. Three patients had multiple CAVFs. The fistula drained into the right ventricle in 13, pulmonary artery in 9, left ventricle in 4, right atrium in 2, and left atrium in 1. Thirteen patients had other associated cardiac lesions. The mean pulmonary-to-systemic blood flow[Qp /Qs] in the isolate CAVF group was 2.19. All patients were operated on to correct the fistulas and other associated cardiac lesions. All patients were followed from 1 month to 11 years without late death. Postoperative complication rate was 24% -significant arrhythmia [3], recurred CAVF[1], psychosis[1], pneumonia [1]. Symptomatic improvement was evident postoperatively. Below 20 years old, 94% of patients were asymptomatic, but above 20 years old, symptoms persisted in 25%. In summary, early elective repair of CAVF is indicated in all patients because of higher complication rate and frequent persistent symptoms in older patients.

Since it was proposed that vanadate may be an ‘ideal endogenous regulator of the $Na^+,\;K^+-ATPase$ activity (Cantley et at, 1979), vanadate has been a subject of intensive research and a variety of its physiological effects have been described (Nechay, 1984). In isolated guinea pig heart muscle vanadate shows a positive inotropic effect on ventricular muscle, while it induces a negative inotropic effect on atrial muscle. But its underlying mechanism has not been elucidated so far. Therefore, in this study the flux rates of calcium ion into and from guinea pig heart muscle were measured to throw some light on the underlying mechanism, because those rates have been known to be closely related to the cardiac contractility and the results are summarized as follows: 1) Calcium efflux rates from the intracellular $Ca^{++}$ pool (compartment 4) of both guinea pig left atrium and right ventricle were significantly reduced by vanadate and their pool sizes were significantly increased by vanadate. 2) The magnitude of calcium influx into left atrium was reduced by vanadate, While the magnitude of calcium influx into right ventricle was not affected by vanadate. From these results, it may be concluded that the positive inotropic effect of vanadate on the ventricular muscle was due to a reduced efflux rate of calcium ion and its negative inotropic effect on atrial muscle was resulted from a reduced influx of calcium ion.

점액종은 심장 종양의 가장 흔한 형태이며 주로 좌심방에서 발견된다. Carney 등에 의하면가 족성을 가지 며 점액종(심장, 피부, 유방), 반점상의 피부 색소침착와 내분비성 질환이 동반된 증후군을 점액종 증후군 이라 명명하였다. 저자들은 얼굴과 좌완에 피부병변이 있고 좌심방과 우측 유두에서 점액종이 발견되고 가 족력이 있는 19세 여자를 Carney 증후군을 가진 가족성 심방 점액종으로 진단하여 좌심방 중격과 승모판에 부착된 점액종을 성공적으로 절제하였다. 심장 점액종의 가족성이 있는 동일 가족 구성원은 증상이 발현되 지 않더라도 심장 점액종을 발견하기 위해 선별적 심방초음파 검사가 주기적으로 실시되어야하며 재발과 다 발성병변이므로 수술시 종양의 완전 절제와 수술후 추적검사가 필요하다.

33세 남자가 심와부 불편감을 주소로 내원하여 흉부컴퓨터단층촬영과 심초음파에서 좌심방 내 점액 종으로 수술적 절제하였다. 12개월 후 외래추적 검사에서 첫 번째 수술과 관계없는 부위인 우심방 내 점액종이 발견되어 재수술하였으며 10개월간 재발 없이 지내고 있다. 우리나라에서는 좌심방 내 점액종 제거 후 재발된 좌심방 내 점액종은 보고된 적이 있지만, 우심방에 재발된 경우는 보고된 바가 없어 치험례를 보고한다.
