a Appearances of the heart after the bi-directional Glenn procedure (Stage 2). Note that the SVC is closed off at or near its junction with the RA in contrast to the hemi-Fontan procedure. IVC: inferior vena cava; LA: left atrium; LV: left ventricle; LMPA: left main pulmonary artery; RMPA: right main pulmonary artery; RA: right atrium; RV: right ventricle; SVC: superior vena cava. b Appearances of the heart after the hemi-Fontan procedure (Stage 2). Note that the SVC remains in continuity with the RA in contrast to the bi-directional Glenn procedure. IVC: inferior vena cava; LA: left atrium; LV: left ventricle; LMPA: left main pulmonary artery; RMPA: right main pulmonary artery; RA: right atrium; RV: right ventricle; SVC: superior vena cava
