The operative problem of small left atrium in total anomalous pulmonary venous connection: report of 5 patients.
A moderately small left atrium is a common finding in total anomalous pulmonary venous connection (TAPVC). In most patients in whom the common pulmonary vein is anastomosed to the left atrium, the small size of this chamber does not interfere with good operative results. Recently a patient was encountered in whom the left atrium measured less than 2 cm in its greatest dimension. This atrium was too small to take an anatomosis with the common pulmonary vein. Therefore the common pulmonary vein was anastomosed primarily to the right atrium, the floor of the fossa ovalis was excised, and a pericardial conduit was constructed. Subsequently, 4 additional patients have been similarly treated. The problem of small left atrium in TAPVC is discussed.
