Total Anomalous Systemic Venous Drainage to the Left Atrium

Abstract

We present an unusual case of total anomalous systemic venous drainage in which the right superior vena cava, persistent left superior vena cava, inferior vena cava, and coronary sinus were present and unusually connected to the left atrium. Successful surgical correction was achieved, and the patient's recovery was uneventful. Various types of total anomalous systemic venous drainage are discussed, and classification of total anomalous systemic venous drainage is made under the consideration of creation of cardiopulmonary bypass.
