Surgical treatment of partial endocardial cushion defect was accomplished in Feb. 1984 in this department. The 5 year old male patient had history of frequent upper respiratory tract infection and since his age of 3 years dyspnea on exertion and palpitation were noted but there were no cyanosis and clubbing. A thrill was palpable on the apex and grade IV/IV harsh systolic ejection murmur and diastolic murmur was audible on it. Liver was palpable about 3 finger breadths and no ascites. Chest X-ray revealed increased pulmonary vascularity, moderate cardiomegaly [C-T ratio; 0.69], and enlarged left atrium. EKG showed first degree heart block, RVH, LVH, and LAD. Echocardiogram showed paradoxical ventricular septal movement and abnormal diastolic movement of the anterior leaflet of mitral valve. Right heart catheterization resulted left to right shunt [Qp:Qs:2.1:1 ] and moderate pulmonary hypertension [60/40 mmHg]. Left ventriculogram showed mitral regurgitation [Grade III/IV] and filling of left atrium and right atrium nearly same time. Operative findings were: 1.Primum type atrial septal defect [3x2 cm] 2.Cleft on the anterior leaflet of mitral valve. 3.No interventricular communication and cleft of tricuspid valve leaflet. The mitral cleft was repaired with 4 interrupted sutures. The primum type atrial septal defect was closed with Dacron patch intermittently at endocardial cushion and continuously remainder. The post operative course was uneventful and discharged on 22nd postoperative day in good general conditions.

Purpose: The purpose of this study was to report the treatment results of patients with traumatic cardiac tamponade after the opening of Jeju Regional Trauma Center. Methods: We analyzed the treatment outcomes of patients with traumatic cardiac tamponade who were treated at Jeju Regional Trauma Center from January 2018 to August 2022. Results: Seven patients with traumatic cardiac tamponade were treated. The male to female ratio was 1.33:1 (four male and three female patients) and the average age was 60.3±7.2 years. The mechanism of injury was blunt trauma in six cases and penetrating injury in one case. Upon arrival at the emergency department, pericardiostomy was performed in four cases, and an emergency operation was performed in six cases. Pericardiostomy alone was performed in one patient, who had cardiac tamponade due to extrapericardial suprahepatic inferior vena cava rupture. The causes of cardiac tamponade were right atrium appendage rupture in one case, right ventricle rupture in one case, inferior vena cava rupture in two cases, right atrium and left atrium rupture in one case, both atria and left ventricle rupture in one case, and intercostal artery rupture in one case. In three cases, intraoperative cardiopulmonary bypass was required. Two of the seven patients died (mortality rate, 28.5%). Conclusions: Relatively favorable treatment results were observed for traumatic cardiac tamponade patients after Jeju Regional Trauma Center was established.

Isolated right ventricular hypoplasia is a rare clinical entity. We describe a case of right ventricular hypoplasia, single atrium and spongy myocardium of left ventricle. The volume of right ventricle was half the volume of left ventricle and z-value of tricuspid valve was -4 preoperatively The patient, 6-year-old boy, underwent atrial partitioning with 3 mm fenestration, Postoperative course was smooth and he tolerated the biventricular state well during follow-up. Follow-up catherterization was done 27 months later The tricuspid valve grew well (z-value= -0.4) and atrial septal fenestration is closed spontaneously. This article reports a case of successful biventricular repair in a patient with isolated right ventricular hypoplasia.

It is generally acknowledged that congenital coronary artery fistula is an abnormal communication of the coronary artery with the right ventricle, right atrium,left atrium and left ventricle. In young people the symptoms are unusual , but significant symptoms and complications appear among the older age group such as congestive heart failure, subacute bacterial endocarditis, coronary steal syndrome, aneurysm formation, rupture, and pulmonary hypertension. Therefore, early surgical treatment is recommended. We experienced a case of coronary arteriovenous fistula that was involving the circumflex branch of the left coronary artery with the right ventricle. It was 10mm in diameter with multiple vegetation. We repaired the fistula under extracoporeal circulation. The patient was discharged in a healthy condition twelve days after operation .

Cardiac Myxoma is a most frequent benign tumor in primary cardiac tumors. About 75% occur in the left atrium & 20% in the right atrium, ventricular Myxoma is a very rare one among the cardiac myxoma. They may cause severe and progressive disease resembling valvular heart disease. With the advent of various diagnostic modalities, especially real time bidimensional echocardiography enabled us more accurate diagnosis of cardiac myxoma noninvasively and preoperatively. From April 1977 to Sept. 1981, 16 cases of cardiac myxomas were operated in Seoul National University Hospital using cardiopulmonary bypass. There were 13 cases of left atrial myxomas and each of a case was right atrial and right ventricular and left ventricular one. In all cases tumors were resected successfully & were discharged in healthy state. Follow up results of each patient was excellent.

Purpose: To optimize the timing of scans using cardiac magnetic resonance contrast-enhanced timing robust angiography (CMR-CENTRA) for electroanatomic mapping (EAM) of the right atrium (RA) and left atrium (LA) in patients with atrial fibrillation (AF). Materials and Methods: Fifty patients with AF (38 men; mean age, $59.6{\pm}9.3years$) underwent CMR-CENTRA in preparation for EAM. The CMR-CENTRA data were acquired at five different scan times: 0 seconds, 5 seconds, 10 seconds, 15 seconds, and 20 seconds after an intravenous injection of contrast media. To evaluate the degree of contrast enhancement, right atrial relative contrast (RA-RC) and left atrial relative contrast (LA-RC) on the CMR-CENTRA scans were assessed at each time point. The three-dimensional (3D) reconstruction of the RA and LA for the EAM system was performed using the CMR-CENTRA data. Results: A CMR-CENTRA at a scan time of 10 seconds showed significantly greater LA-RC (P < 0.05) compared with all other scan times. A CMR-CENTRA at a scan time of 15 seconds showed significantly greater RA-RC (P < 0.05) compared with all other scan times. In the 3D reconstruction of the RA, the success rates of CMR-CENTRA at scan times of 10 seconds and 15 seconds were 18% and 100%, respectively. In the 3D reconstruction of the LA, the success rates of CMR-CENTRA at 10- and 15-second scan times were 100%. Conclusion: The CMR-CENTRA data acquired at 15 seconds after the injection of contrast media is appropriate for the preparation of an EAM system that is focused on the RA and LA in patients with AF.

Cor triatriatum is a rare congenital malformation of the heart in which a septum stretches in a transverse plane through the left atrium, thus creates two left atrial subchambers. The upper one connects with the pulmonary veins, and the lower connects with the left ventricles. Due to the rarity of, and difficulty in diagnosing car triatriatum, data on the surgery of the disease are of necessity and very limited. A case of cor triatriatum combined with atrial septal defect and persistent left superior vena cava was experienced in November, 1984 in Chonnam University Medical School. There was a transverse septum in the left atrium below atrial septal defect, all pulmonary veins were drained into the upper chamber of the left atrium which connected with the right atrium via atrial septal defect and the lower chamber via an oval opening[8mm] in the abnormal septum and the lower chamber was connected with the left atrial appendage, and the left ventricle via mitral valve. There was persistent left superior vena cava drained to left atrium and coronary sinus. The abnormal transverse septum within the left atrium was completely excised and the atrial septal defect was repaired with Woven Dacron patch. The post-operative course was not eventful and the patient was discharged to home with good result on the 15th postoperative day, and has been in good condition upto now.

A primary malignant lymphoma that originates in the heart is extremely rare. A 68-year-old male patient was admitted due to aggravated dyspnea. After echocardiography and chest computed tomography evaluation, a huge mass in the right atrium and the right ventricle was detected. We decided to perform emergency surgery due to a high risk of infarction and hemodynamic disturbance. After the near total removal of the huge mass in the right cardiac chamber, the interatrial septum and antero-lateral part of the right atrium were reconstructed by the use of a bovine pericardial patch. The final pathological diagnosis was a primary malignant lymphoma. The patient and his guardians refused chemotherapy (including radiotherapy), and the patient was discharged to his home, where the prognosis was hopeless.

The role of positron emission tomography (PET) with F-18 fluorodeoxyglucose (F-18 FDG) in the diagnosis of hepatocellulcar carcinoma (HCC) has been limited because of a variable FDG uptake in HCC. However, the usefulness of PET/CT for detecting extrahepatic metastasis and monitoring of the treatment response in HCC has been reported. A 55-year-old man with a hepatitis B surface antigen-positive, was admitted to our hospital due to dyspnea, general weakness and body weight loss for one month. Chest X-ray showed multiple reticulo-nodular densities on both lower lung fields, which implies metastatic lesions. F-18 FDG PET/CT revealed consecutively intense hypermetabolic mass in right hepatic lobe, inferior vena cava and right atrium. We report a case of HCC with IVC and right atrium invasion identified by F-18 FDG PET/CT.

Two patients operated upon for tricuspid atresia by Glenn operation are presented. They were five years old and four years old females who were cyanotic shortly after birth, and remained cyanotic. On physical examination, cyanosis on digits and lips, clubbing of fingers, thrill and grade III systolic murmur on 4th I.C.S. along left sternal border were noted. In the first case, chest roentgenograms showed normal pulmonary markings, and the electrocardiogram was interpreted as showing left ventricular hypertrophy with left axis deviation and peaked P-wave in lead IL Right heart catheterization showed high pressure in right atrium and the catheter tip was easily inserted into the left atrium through septal defect. In the second case, chest roentgenograms showed cardiomegaly with sparse pulmonary vascular markings and narrowed vascular pedicle, and the electrocardiogram showed left ventricular hypertrophy with some element of right atrial hypertrophy. Angiocardiogram showed changes characteristic of tricuspid atresia, including "right ventricular window" The findings of right heart catheterization were similar to those of first case. On the basis of these observations, they were diagnosed as tricuspid atresia, and Glenn operation was performed. Normal position of great vessels combined with ventricular septal defect and pulmonary stenosis were noted on the first case, and on second case, transposition of great vessels was additional finding. Postoperative course was uneventful and favorable outcome was obtained.
