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.

Cor triatriatum is a rare entity of congenital heart disease characterized by the presence of a fibrousmuscular diaphragm that subdivides the left atrium into a proximal or "accessory" chamber and a distal or "true" left atrial chamber. In the other hand, cor triatriatum is a variant of abnormal connection between the pulmonary vein and true left atrium which is separated from accessory left atrium receiving pulmonary venous blood flow by fibromuscular diaphragm. We experienced two cases of cor triatriatum. One of them was classical, and the other case was combined with atrial septal defect and all pulmonary veins were drained into the " common pulmonary venous chamber " which connected with right atrium and there was no direct communication between the accessory chamber and true left atrium. The abnormal diaphragms were excised and the atrial septal defect was repaired with pericardial patch in case II. The postoperative courses were not eventful and the patients were discharged with good result, and have been in good condition upto now.n good condition upto now.

Cor triatriatum is a relatively rare cardiac anomaly, whose major feature is a fenestrated membrane separating an upper common pulmonary venous chamber from a lower true left atrial cavity. Interatrial communications may be present between the right atrium and the common pulmonary venous chamber or the true left atrium. From April 1981 to April 1992, 24 patients with cor triatriatum were treated at Seoul National University Hospital. Ages ranged from 1 month to 24 years with mean of 7.4 years. Twenty patients had interatrial communications through a patent foramen ovale, primum or secundum defect of the atrial septum. Four had no interatrial communications. Fourteen patients had associated anomalies; partial anomalous pulmonary venous connection in 3, total anomalous pulmonary venous connection in 2, persistent left superior vena cava in 3, and other anomalies in 6 patients. Surgical corrections were performed through right atriotomy in 18 patients, left atriotomy in 4, and both atriotomy in 2. Three patients [12.5%] died early after operation; two of them were associated with single ventricle. Six out of 21 survivors [28.6%] experienced complications; recurrent pneumonia, pulmonary embolism, ischemic encephalopathy, diaphragmatic palsy and tachyarrhythmias. At the time of follow up, all survivors, except one, were in functional class I. Surgical correction of cor triatriatum restored normal hemodynamic status with relatively low operative mortality, especially in patients not complicated with severe anomalies. This report summarizes the clinical diagnosis, associated anomalies, interatrial communications, surgical approach and late result of 24 patients underwent surgical corrections in our hospital.

In a newborn in whom cor triatriatum was missed on echocardiography, infracardiac total anomalous pulmonary venous connection was successfully repaired with the aid of cardiac computed tomography (CT). In rare combinations, as in this case, an accurate diagnosis prior to surgery, which is of vital importance for successful repair, can be made through a high index of suspicion and the use of a supplemental imaging modality such as CT.

We herein present a case of a successful correction of cor triatriatum associated with thrombotic pulmonary hypertension diagnosed in an adult female patient. We confirmed diagnosis using transthoracic and transesophageal echocardiography in addition to cardiac computed tomography and magnetic resonance imaging. Surgical repair comprised excision of the fibromuscular membranous septum in the left atrium, patch closure of an atrial septal defect, and reconstruction of the pulmonary arteries with a vascular graft. Cor triatriatum complicated pulmonary thrombotic hypertension with atrial septal defect is amenable to surgical correction with satisfactory results.

A 3-year-old chow chow dog with abdominal distention was referred to the Veterinary Teaching Hospital of Chungnam National University. The dog was diagnosed as Cor triatriatum dexter based on echocardiographic results, which demonstrated an abnormal membrane partitioning the right atrium. Echocardiography also revealed turbulent intra-atrial blood flow between the two chambers of the atrium. The dog was treated with balloon dilatation to enlarge the perforation in the abnormal membrane and to improve blood flow. As a result, although the membrane remained, increased perforation reduced the turbulent intra-atrial blood flow. Clinically the patient improved and eventually was discharged. This case is the first domestic Korean clinical veterinary report on the use of balloon valvuloplasty to treat Cor triatriatum dexter in a dog.

노령에서의 삼심방심은 드문 질환이다. 본 증례는 66세된 남자로 관상동맥 질환과 삼심방심으로 진단되었다. 삼심방심의 수술소견상 좌심방을 두 방으로 나누는 10 mm 크기의 개구를 가진 막성중격이 있었고, 폐정맥들은 근위부에 위치하는 방에 연결되어 있었다. 그 외 폐정맥의 연결이상이나 심방중격결손등의 다른 기형은 없었다. 좌심방내의 막을 절제하고 카펜티어 에드워드링으로 승모판을 재건해 주었으며 관상동맥우회로술을 성공적으로 시행하였다.

A rare anomaly, Cor triatriatum dexter combined with pulmonary stenosis and patent foramen ovale in a 2-years- old female is presented. Abnormal embryologic development of the right sinus venosus valve caused partial membranous septation of the right atrium. Most cases have been recorded at necropsy either as an incidental finding or in association with severe congenital heart disease. In this case, Cor triatriatum dexter was diagnosed preoperatively by cineangiography and echocardiography.

Cor triatriatum is a rare congenital malformation of the heart in which a diaphragm stretches in a transverse plane through the left pulmonary venous chamber, thus creates two subchambers. The proximal chamber connects with the pulmonary veins, and the distal one has left auricle and the mitral valve. A 3 year old boy who had Cor triatriatum underwent surgical excision of the abnormal diaphragm in March, 1989 in Chungnam University Hospital. An obliquely oriented fibromuscular diaphragm divided the left atrium into a proximal chamber which was connected to the pulmonary veins and a distal chamber which had the atrial appendage and the mitral valve. The opening in the diaphragm was 5 mm in diameter. There were no associated abnormalities. The abnormal diaphragm was completely excised. The postoperative result was excellent.

An approximately 8-month-old, 2.61 kg, male Siamese kitten was referred with primary complaints of a 1-week history of respiratory distress, exercise intolerance and dyspnea. Diagnostic studies identified III/VI systolic murmur in the cardiac auscultation, right ventricular enlargement patterns in the electrocardiogram, pleural effusion and right-sided cardiomegaly in the thoracic radiography, and right marked ventricular dilatation, right atrial enlargement, atrial septal defect and abnormal left atrium divided by fibromuscular membrane. Based on these findings, the case was diagnosed as cor triatriatum sinistrum complicated with an ostium primum atrial septal defect. The cat was rescued with furosemide, nitroglycerine, oxygen supplement and fluid removal from pleural cavity.
