Fontan circulation. a) Modified atriopulmonary connection Fontan in which the systemic venous atrium is directly connected to the pulmonary arteries; b) inferior vena cava flow streamed directly to the pulmonary arteries in a right atrium lateral tunnel Fontan; and c) extracardiac conduit connecting the inferior vena cava to the pulmonary arteries. The latter two operations (b and c) are forms of total cavopulmonary connection (TCPC) Fontan, and show a fenestration between the total cavopulmonary connection pathway and the right atrium, a common surgical modification performed to relieve pressure in the pathway. RPA: right pulmonary artery; LPA: left pulmonary artery; SVC: superior vena cava; RA: right atrium; LA: left atrium; IVC: inferior vena cava; RV: right ventricle; LV: left ventricle.
