Snowman heart

Abstract

Total anomalous pulmonary venous connection (TAPVC) consists of abnormality of blood flow in which all pulmonary veins drain into systemic veins or into right atrium with or without pulmonary venous obstruction. Systemic and pulmonary venous blood mix in right atrium. An atrial septal defect is required for survival. We report a case of supracardiac TAPVC and discussed about its diagnostic and management approach.
