Tricuspid valve dysplasia was diagnosed in 2 month-old german shepherd dog. Radiographic and echocardiographic examination was performed and they revealed severe dilatation of the right atrium, dilatation of the right ventricle, and septal leaflet tethered to the right side of the septum. On Doppler echocardiography, tricuspid valve incompetence was detected, flow velocity ranging from 3-4 m/sec. Color Doppler examination showed large turbulent jet in the right atrium.

We experienced one case of the calcified giant thrombosis in the enlarged right atrium and coronary sinus with markedly dilated persistent left superior vena cava and absent right superior vena cava in 29year old female patient. We supposed that the dilatation of persistent left superior vena cava was due to poststenotic dilatation secondary to obstruction on orifice of coronary sinus by thrombosis. The giant thrombosis in the right atrium and coronary sinus was successfully resected. She had improvement on preoperative chest discomfort but, the moderate hepatomegaly was developed and then she was discharged with incompletely recovered state due to economical poverty on postoperative 6th weeks. The continuous follow-up and study are indeed necessary for further evaluation of pathology and etiology.

We experienced 6 cases of primary cardiac tumor, all received operation for removal of tumor. Mean age was 43.8 years-old ranging from 17 years-old to 66 years-old. Five cases were female, one case was male. Five cases were benign, myxoma, all located within left atrium. One case was malignant, angiosarcoma within right atrium. All patient showed cardiac manifestations. One case was in NYHA functional class II, two were in III, three were in IV. Four patients showed constitutional symptoms, but no one showed evidence of embolic phenomenon. All case of myxoma showed cardiomegaly except one malignancy. Only one case was regular sinus rhythm, three were sinus tachycardia 8z two were atrial fibrillation. The most common site of tumor origin was fossa ovalis limbus[four of all]. Two of five myxomas received emergency operation, one patient died postoperatively. Lived four patients showed no evidence of recurrence[mean follow-up, 3,5 years], but one patient has Grade II /IV mitral regurgitation & in OPD follow-up now, One malignant case, 17 years-old cerebral palsy female, was angiosarcoma occupied most of right atrial chamber originated from anterior wall of right atrium, received emergency operation which was removal of mass & reconstruction of right atrium with artificial pericardial patch. This patient died on postoperative 36th day due to persistent LCOS[low cardiac output syndrome] with combined sepsis.

Sector scanner which has a conical end is used to image through the intercostal space because heart is protected by the ribs. Cardiac data published all around the world were also obtained by sector scanner. Although scanners being used in every small animal practice and animal hospital at college in Korea include convex ape and linear type, linear type is not appropriate f3r cardiac scan because of a wide contact surface. The purpose of this study is to establish ultrasonographic images of normal cardiac structures by measuring shape, size of reflectable cardiac structure according to restraint position in scanning normal heart of the puppies with 6.5 MHz convex scanner(SonoAce 4500, Medison, Korea) used in our veterinary teaching hospital, Seoul national university. Seventeen male and female puppies considered having healthy hear by X-ray and clinical examination are used feom April to July 1994. Scanning point selection of probe head and the distinction of imaged cardiac structures were accomplished by necropsy and cardiac scanning performed through thoracotomy under general anesthesia. At 10 o'clock position of transducer(at an angle of 30$^{\circ}$ between imaginary line from elbow joint to 3rd sternum and probe head, 60$^{\circ}$ from body surface, 4th intercostal space of right thorax) with the marker of scanner toward the head of dogs right atrium, left atrium and left ventricle were observed in 2, 3, 4, 5 intercostal space(2cm from the sternum) of experimental dog positioned ventrodorsally under general anesthesia. Under these conditions, the numerical values of imaged diastolic hear are as follows : the distance from skin to apex(mean$\pm$S.D) 47.53$\pm$6.94mm, thickness of left ventricular wall 6.00$\pm$1.60mm, length of left ventricle 16.27$\pm$5.31mm, width of left ventricle 15,33$\pm$4.25mm, length of left atrium 12.33$\pm$3.82mm, width of left atrium 11. 33$\pm$3.94mm, length of right atrium 1.00$\pm$2.41mm, width of right atrium 11.21$\pm$2.76mm and the area of left ventricle 270.92$\pm$109.81mm$^2$, area of left atrium 98.00$\pm$41.08mm$^2$, area of right atrium 62.75$\pm$21.04mm$^2$.

Gebode defect, that can accurately be treated surgical repair, is defined as a true communication between left ventricle and right atrium. A 74-year-old woman with a worsening history of ortophnea and peripheral edema was hospitalised. A communication between right atrium and left ventricle was diagnosed using transeusophageal echocardiography. The defect was repaired and mitral valve was replaced with a biologic valve. It would be beter to tailor surgical strategy for each case with atrioventricular canal defect after preoperative transeusophageal echocardiography and peroperative direct sight.

We will report 6 cases of cardiac tamponade treated surgically at Severance Hospital during the past 9 years from 1964 to 1972 and reviewed literatures on cardiac tamponade. The age of patients was from 13 years to 45 years old. The male was 4 cases and the female 2 cases. The sites of injury were right atrium; 1 case, right ventricle; 2 cases, right ventricle and coronary artery; 1 case, left atrium; 1 case, and left ventricle; 1 case. 2 cases of cardiac tamponade developed following chest injury, 2 cases following pericardiocentesis,1 case due to continuous bleeding from sutured cardiotomy wound of left atrium following open mitral commissurotomy using cardiopulmonary bypass machine, and 1 case due to traumatic penetration of polyethylene catheter through right ventricle to pericardial sac, introduced via right jugular vein in order to monitor the central venous pressure. Central venous pressure was checked preoperatlvely in 5 cases. In all cases, central venous pressure was rised [the range of central venous pressure was 240 to 330 mmHg]. Immediately after operation,central venous pressure lowered to normal [the range was 80-100 mmHg]. Recently serial gas analysis of arterial blood were checked pre- and post-operatively for the evaluation of hemodynamic change of cardiac tamponade, but our data was not enough for evaluation. It should be studied further.

우심방과 관상정맥동의 선천성 기형은 크게 4 가지로 분류되는데, 전반적으로 확장된 우심방, 단일 낭성 게실(saccular diverticula), 다발성 낭성 게실, 그리고 우심방이나 관상정맥동에서 발생한 류(aneurysm)이다. 환아는 평소 건강하였으며, 우연히 시작된 상기도 감염증상으로 내원하여 시행한 단순 흉부 촬영 및 심초음파에서 다른 동반 기형 없이 우심방의 심한 확장을 발견하였다. 확장된 우심방은 심폐기 보조하에서 광범위한 절제를 시행하였으며, 병리학적 검사에서는 심내막 및 심외막에 경도의 섬유화를 동반한 국소 다발성 심근소실의 소견을 보였다. 본원에서는 6세 환아의 선천성 우심방 류를 광범위한 우심방 절제를 통해 교정했기에 이에 문헌 고찰과 더불어 증례 보고하는 바이다.

Chiari's networks are present in 1.5% to 4% of the population. They are a congenital disease characterized by a remnant of the right valve of sinus venosus and rarely have clinical significance. Chiari's network, as the name implies, has network-like shape, but there are other forms of appearance. We have experienced a case of a 60-year-old woman who had a cystic mass on the right atrium. Surgical treatment was performed forthe mass removal and differential diagnosis of the mass. There was no evidence of other tumor, but Chiari's network. As cystic form of Chiari's network have not been reported before, it is the first report of cystic form of Chiari's network.

Primary cardiac lipoma is an extremely rare condition. We reports a case of primary lipoma located mainly in the right atrium of the heart in a 58-year-old male patient. The initial presenting symptoms were dyspnea followed by rapidly progress!ve congestive heart failure. Echocardiogram revealed huge mass on right atrium with stalk arising from septum. Under cardiopulmonary bypass the mass was removed and revealed characteristic findings of lipoma on microscope. The patient was recovered without any problem. We would like to describe this case of rare tumor with the review of literatures.

A fistula between the right pulmonary artery and the left atrium is a very rare congenital anomaly, for which there is no definitive embryogenetic explanation. Patients present with cyanosis or clubbing, and the treatment strategy is to close the fistula, which can be done by an open surgical technique or by percutaneous intervention. Although rare, this condition should be considered in the differential diagnosis when evaluating a patient with central cyanosis.
