The coronary sinus (CS) is the venous drainage system of the heart. CS ostium atresia is a rarely seen cardiac malformation. Congenital atresia of the CS is usually found together with persistent left superior vena cava (LSVC) and other cardiac malformations. However, isolated congenital atresia of the CS is very rare. We present a rare case of isolated congenital atresia of the CS connecting the left atrium and coronary veins without persistent LSVC in a 58-year-old female.

It is well known that the morphologic feature of coronary artery is variant as finger print. Left coronary artery is divided into the left anterior descending artery and circumflex artery and supplies almost left atrium, left ventricle and interventricular septum. Clinically, the morphologic features of number of branches and the length of the left main coronary artery are important. In Korea, there are few reports about morphologic study of the coronary artery, and the coronary angiogram and open heart surgery are common. Now the author studied the morphology of the proximal part of the left coronary artery in Korean 50 Adult cadavers and obtained the following results: 1. The length of the left main coronary artery is from 5 mm to 16 mm [mean 9.7 mm]. 2. The diameter of the proximal part of the left coronary artery is from 3.2 mm to 7.7 mm [mean 5.3]. 3. The features of the branching are bifurcation [58%] trifurcation [38%] and quadrifurcation [4%]. 4. The diameter of the left anterior descending artery is from 2.7 mm to 8.1 mm [mean 4.5] and circumflex artery from 2.1 mm to 6.2 mm [mean 3.9].

An 11-year-old, castrated male dog presented with a 3-month history of cough and depression. Auscultation revealed systolic murmur and thoracic radiographs showing enlargement of both the atrium and left ventricle. Echocardiography showed thickened mitral valve and moderate-to-severe left atrial enlargement. Additionally, M-mode echocardiography showed symmetric left ventricular wall thickening and systolic anterior motion of the mitral valve, while Doppler imaging revealed high velocity turbulent flow through the left ventricular outflow tract. Based on echocardiography, this case was diagnosed with hypertrophic obstructive cardiomyopathy. After 5 months, the dog was clinically static in radiography and echocardiography.

Congenital coronary fistula is a rare condition, and with widespread use of cardiac catheterization, angiography and selective coronary arteriography are being recognized with increasing frequency. Fistula originating from the right coronary artery are more common than those from the left coronary artery. The fistula empties into the right side of the heart in 90% of the cases with the right ventricle being the most common recipient chamber, followed by the right atrium and the pulmonary artery. We report a case of congenital coronary artery fistula of the right coronary artery to the left ventricle with significant shunt in a 20 - year old female. It was detected by transthoracic and transesophageal echocardiography and confirmed by cardiac catheterization and coronary angiography. The fistula opening was closed with 6-0 Prolene continuously under cardiopulmonary bypass and moderate hypothermia [ 28 oC ]. Postoperative course was uneventful and the patient was discharged without specific problem.

Left atrial myxoma, an unusual clinical entity, may cause severe and progressive cardiac disease mimicking mitral valvular disease. In recent years, increased clinical awareness and improved diagnostic techniques has led to a higher incidence of correct preoperative diagnosis. Recently we experienced 2 cases of left atrial myxoma, which were removed successfully under the cardiopulmonary by pass. The first case was 45 years old woman and the second was 23 years old female. Preoperative definite diagnosis was entertained by angiocardiography and echocardiography in both cases. In the first case, tumor was removed with left atriotomy and atrial septectomy was done with additional right atriotomy. In the second case, tumor and atrial septum were removed en bloc through the right atrium. Both patients were discharged with good results 2 weeks postoperatively.

Total anomalous pulmonary venous return (TAPVR) is very rare congenital heart disease. 25-year old male was admitted our hospital with dyspnea, headache and syncope as chief complaint. He was confirmed as mixed type TAPVR by echocardiography and cardiac catheterization. In this case, mixed type TAPVR was consisted with supracardiac type connection of left pulmonary vein and cardiac type of right pulmonary vein. Supracardiac type of left pulmonary common channel was anastomosed to the left auricular appendage during total cardiopulmonary bypass with fibrillating heart. Cardiac type of right pulmonary vein was operated during moderate hypothermia and aortic cross clamping. Coronary sinus septum was incised into ASD and closed with Gore-Tex patch so that right pulmonary blood flow directed to the left atrium. The patient's post-operative course was uneventful.

Intralobar pulmonary sequestration is a rare congenital malformation characterized by a cystic portion of the lung that derives its arterial blood supply through aberrant vessel directly of systemic circulation. Intralobar pulmonary sequestration Is usually contained within the visceral pleura of a pulmonary lobe and its venous drainage to the pulmonary venous system. We experienced a case of pulmonary sequestration preoperatively confirmed. The patient was 17 year old female whose complaints were mild fever and profuse purulent sputum. Chest film showed a large thin walled cystic lesion with air-fluid level at the left lower posterior basal lung field. Aortogram revealed an aberrant artery originated from thoracic aorta just above the diaphragm and that drained via pulmonary vein into the left atrium. At time of operation, a large abscess cavity measuring 9x8x3 cm in dimension at the left lower lobe was noted. And the aberrant artery, measuring 0.5 cm in diameter and 2 cm in length, arising from thoracic aorta just above the diaphragm was noted. After division and ligation of the aberrant artery, a left lower lobectomy was performed and the patient`s postoperative course was uneventful.

Cor triatriatum is a rare congenital heart disease that is often lethal in children if not correctly identified and properly managed, Characteristically an anomalous membrane divides the left atrium into two chambers one located posterosuperiorly which is connected to the common pulmonary venous trunk and the other anteroinferiorly which is connected to the left atrial appendage and the mitral valve. Eight patients with Cor triatriatum were been seen at our hospital from 1984 to 1999. The clinical presentation diagnostic evaluation and surgical results are outlined in this retrospective review. Resection of the obstructing anomalous atrial membrane was performed using a hypothermic cardiopulmonary bypass in all cases. Right atriotomy was performed in all patients and left atriotomy was performed in a patient who had poor preoperative general conditions and serious cardiac defects(TAPVR & hypoplastic left ventricle) died of low cardiac output during the immediate postoperative period. The postoperative course has been excellent in the remaining. Cor triatriatum is amenable to surgical repair with excellent results when diagnosed early and in those who are not complicated by other complex cardiac anomalies.

Primary and metastatic tumors involving the heart are relatively uncommon in dogs. In this study, we provide the echocardiographic diagnosis of intracardiac masses in 2 Yorksire terrier dogs. In the first case, the mass was attached between ascending aorta and pulmonary artery and caused moderate aortic regurgitation and moderate left ventricular dilation. The case was graded into ISACHC II heart failure. The dog was treated with common cardiac medications (i.e. furosemide, enalapril, pimobendan) and oral chemotherapeutic agent (i.e. lomustine). In the second case, the mass was occupied 2/3 of the left atrium and caused marked dilation of left atrium and severe mitral regurgitation (~5 m/s), but not severe congestive heart failure (ISACHC Ib). Although the nature of progression of the mass was likely to cardiac myxoma, the biopsy was not performed due to the owner's refusal. The dog was currently treated with cardiac medications (i.e. ramipril, clopidogrel) and bronchodilator (i.e. aminophylline). Those two dogs are still survived and are currently regularly checked.

Sixty-eight consecutive patients have been subjected to total corrective surgery of tetralogy of Fallot at the Hanyang University Hospital between August 1975 and December 1984. Of these, the pressure of chambers and great arteries were measured, before and immediately following an operation in 39 of the survived group and 11 of the expired group. The values of postoperative peak pressure were correlated with the outcome of the operation. The result are as followings; 1] Compared to the average peak pressure of right atrium in the survived group, 14.46*4.16 mmHg, that in the expired group, 19.36*8.19 mmHg, was significantly lower, 2] Compared to the average systolic pressure of right ventricle in the survived group, 56.72z16.37 mmHg, that in the expired group, 70.45*15.26 mmHg, was significantly lower. 3] Compared to the average systolic pressure of pulmonary artery in the survived group, 33.26*12.95 mmHg, that in the expired group, 37.55*11.63 mmHg, was higher. But the difference was not significant. 4] Compared to the average peak pressure of left atrium in the survived group, 17.41*6.90 mmHg, that in the expired group, 31.18*12.47 mmHg, was significantly higher. 5] Compared to the average systolic pressure of left ventricle in the survived group, 103.82~12.83 mmHg, that in the expired group, 90.55*20.02 mmHg, was significantly lower. 6] Compared to the average value of the right ventricle-pulmonary artery systolic pressure gradient [RV-PA] in the survived group, 24.95a15.44 mmHg, that in the expired group, 35.09*17.01 mmHg, was significantly higher. 7] Compared to the average value of the right ventricle to left ventricle systolic pressure ratio [RV/LV] in the survived group, 0.55*0.15, that in the expired group, 0.80a0.20, was significantly higher. 8] Compared to the average value of the pulmonary artery-left atrium peak pressure gradient [PA-LA] in 15.85x12.29 mmHg that in the expired group, 4.18x6.00 mmHg, was significantly lower. It is, therefore, suggested that in the operating room, PA-LA is as valuable as RV - PA, RV/LV in making important surgical decision and predicting the prognosis.
