Supramitral ring is a very rare cardiac lesion which frequently associated other congenital anomalies of the heart and great vessels. We present a case of isolated supramitral stenosis ring of the left atrium without an associated lesion who have had operated in this hospital. He was 22 months old male and postoperative course was excellent. The importance of careful clinical examination, angiocardiography, echocardiography before operation is emphasized. Since this lesion is potentially curable by operation, repair with use of cardiopulmonary bypass should be performed without delay once the diagnosis has been made.

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.

This is a case report of total anomalous pulmonary venous drainage with Atrial septal defect, which was corrected surgically by intracardiac procedure under total cardiopulmonary bypass. This 9 years old girl, she complained mild cyanosis, exertional dyspnea, and frequent upper respiratory infection from 3 months age. The chest X-ray showed cardiomegaly and a "snow man appearance", she has systolic murmur with splitting of S2. The diagnosis was confirmed with right heart catheterization, the catheter was reached to right pulmonic vein passed through right atrium, right superior vena cava, innominate vein, left superior vena cava, and common venous trunk. On 28th, Dec. 1979, an anastomosis between common pulmonary venous trunk and left atrium, Pericardial patch closure of ASD, and ligation of left superior vena cava were performed with Extra-corporeal circulation. The postoperative course was uneventful and discharged with excellent general condition.Total Anomalous Pulmonary Venous Drainage with A.S.D. with A.S.D.

Anomalous origin of left coronary artery from pulmonary artery(ALCAPA) is a rare fatal congenital anormaly that needs early surgical intervention. Many reports say that the choice of operative procedure is reimplantation of the left coronary artery into the ascending aorta. We experienced the surgical management of a case of the ALCAPA. The patient was 44 days old and 3.45 kg weighed female baby who had a symptom of congest ve heart failure. She underwent implantation of coronary artery on the aorta with cardiopulmonary bypass and recovered without any complications.

Isolated congenital left ventricular diverticulum is a rare cardiac malformation. Here, we report the case of a 33-year-old woman who had suffered from recurrent transient ischemic attacks for 6 years. Preoperative cardiac magnetic resonance imaging and computed tomography angiography revealed a diverticulum near the apex. The diverticulum was successfully obliterated by cardiopulmonary bypass. We suggest that isolated congenital left ventricular diverticulum can be easily corrected with a low surgical risk by patch repair and plication techniques.

From March, 1983 to June, 1994, twenty-two patients underwent coronary artery and combined operations. The ages of the patients ranged from 42 years to 72 years (mean 60.4$\pm$8.2 years). There were 17 male and 5 female patients. The left ventricular (LV) ejection fraction ranged from 25% to 65% (mean 46.9$\pm$14.2%). Nine patients had mechanical complication of myocardial infarction (MI), of which 5 were LV aneurysm, 3 ventricular septal defect and 1 mitral regurgitation. Nine patients had rheumatic valvular heart disease of whom 7 with aortic valve disease and 2 with mitral valve disease. Two other patients had left atrial thrombi, only one with atrial septal defect a d another with aneurysm of ascending aorta. An average of 2.1$\pm$1.0 bypasses was done, ranging from one to four. There were 3 postoperative complications; 2 perioperative MI and 1 leg wound infection. Among complicated patients, mortality was 1 patient (4.5%) due to low cardiac output syndrome after perioperative MI. With 3 to 136 months follow-up (mean 41.1$\pm$40.2 months), late mortality was 1 patient due to cerebral vascular accident. Among long-term survivors, all patients are in New York Heart Association functional class I or II. Although the number of patients was small, our surgical results were favorable. Therefore we think that coronary revascularization combined with heart operation does not increase the operative risk when associated coronary artery disease is present, and it reduces the occurrence of late death.

The primary cardiac tumor was considered as a form of disease with poor prognosis in the past and it was hardly diagnosed before post mortem autopsy. But recent development of diagnostic procedure and the cardiac surgery using extracorporeal circulation increased the accuracy of diagnosis and the opportunity of successful treatment. The authors present two cases of left atrial myxoma which experienced during recent 4 years between 1979 and 1982. A 33 year old woman admitted with severe shortness of breath, generalized edema, ascites and the evidence of hepatopathy resulted from right sided heart failure. Preoperatively, the patient was treated with conservative medication to improve general condition for a few days. The tumor mass was removed successfully under the cardiopulmonary bypass. She, however, died of myocardial dysfunction showing low blood pressure. The tumor mass weighed 22gm and measured 5.2x4.5x3.6 cm in size. A 60 year old man admitted with shortness of breath on exertion and an episode of fainting. Following the removal of tumor mass under the cardiovascular bypass, the clinical course was satisfactory with no complication. The tumor mass weighed 105gm and measured 9x4x5 cm in size.

Plasma protein concentration, plasma albumin concentration, hematocrit, and arterial blood gas tension were measured in 15 mongrel dogs undergoing heart transplantation with cardiopulmonary bypass. The hemodilution due to priming solution resulted in a 49% decrease in plasma protein concentration, a 57% decrease in plasma albumin concentration, a 46%a decrease in hematocrit. The measurements had returned to preperfusion values 1 hour after the end of cardiopulmonary bypass. The intraoperative changes in plasma protein and albumin concentration did not correlate with changes in alveolar-arterial oxygen tension gradients[D[A\ulcorner PO2]]. It is concluded that, in the absence of an increase in left atrial pressure, marked decrease in plasma protein concentration can be tolerated without the occurrence of pulmonary edema. And further study should be done to determine how to prepare an ideal priming solution.

Background: Patch angioplasty is an alternative surgical procedure to coronary artery bypass grafting (CABG) for left main coronary ostial stenosis. The purpose of this study is to evaluate the outcome of patch angioplasty by analyzing the short-term and long-term results. Material and Method: Twenty nine patients who had undergone patch angioplasty due to left main coronary ostial stenosis between July 1991 and May 2003 were enrolled in the study. The mean age of the patients was 53.1 $\pm$12.5 years. There were 8 males and 21 females, and there were 12 female patients who had no risk factor for atherosclerosis. Twenty six (89.7%) patients showed isolated coronary ostial stenosis without any distal coronary lesion. Result: Anterior approach was used in 28 patients and superior approach was used in one patient. Transsection of the main pulmonary artery was used in one patient. Concomitant CABG was performed in 4 patients because of left anterior descending artery lesions in 3 patients and unstable postoperative hemodynamic status in one patient. Hospital mortality had occurred in one patient (3.4%) and late mortality also in one patient, therefore the overall 5 year survival rate was 91.2$\pm$6.1%. Seventeen coronary angiographies were done in 13 patients (44.8%) postoperatively. Two distal patch stenoses, 1 proximal patch stenosis, and 1 new right coronary ostial lesion were identified and 3 percutaneous interventions and 1 CABG were performed during the follow-up period. The overall 5 year freedom from reintervention rate was 82.4 $\pm$ 8.5%. Aortic regurgitation less than grade 1 had developed postoperatively in 4 patients and one patient showed progression of preexisting aortic regurgitation from grade II to III. Conclusion: Patch angioplasty in left main coronary ostial lesion showed acceptable short-term and long-term results in this study. However, restenosis at the patch anastomosis site and aortic regurgitation should be carefully investigated during the follow-up period.

Obstructive intracardiac lesions, like mitral stenosis or insufficiency (MR), by myxomas of the left atrium have been commonly reported, but the attenuation of MR by myxoma combined with coronary artery disease is very rare. We report a 70-year-old female patient whose left atrial myxoma had attenuated moderate MR to mild MR and required mitral valve surgery after removal of the myxoma. She also had coronary artery disease, severe pulmonary hypertension and moderate tricuspid regurgitation due to the mitral valve lesions obstructed by myxoma. The patient underwent removal of myxoma, mitral and tricuspid valve reconstructions, and coronary artery bypass grafting. She was discharged at the postoperative 14 day without any problems.
