Asymptomatic Total Anomalous Pulmonary Venous Connection with Double Drainage in a Young Adult: A Case Report
AbstractTotal anomalous pulmonary venous connection is an uncommon congenital anomaly in which all pulmonary venous return drains to the right atrium or one of its tributaries. Survival beyond infancy without surgical palliation is unlikely, so this anomaly is not encountered in the adult population with congenital heart disease. The patient presented here was 22 years old on admission and had no total anomalous pulmonary venous connection-associated symptoms. He underwent transthoracic echocardiographic examination for atypical chest pain. Transthoracic echocardiography along with cardiac catheterization favored the presence of a total anomalous pulmonary venous connection. Surgical correction of pulmonary venous confluence (draining to both the coronary sinus and right atrium) was performed successfully. This is a rare case of total anomalous pulmonary venous connection with no reported symptoms in contrast to the majority of patients who are symptomatic during the first year of life.
