Fig. 6

A 21-year-old female with partial unroofing of the coronary sinus and persistent LSVC. Oblique cine balanced SSFP image (a) shows the communication of the LSVC and the left atrium. Phase-contrast mapping of the main pulmonary artery (b) and aorta (c) indicates net forward flow of 130 ml and 80 ml per beat respectively, giving rise to a Qp:Qs ratio of 1.6:1. The phase-contrast image also demonstrates caudal blood flow in the LSVC (*). Serial reconstructed CCT images (d, e, f) show contrast leak from the LSVC (*) into the left atrium before reaching the right atrium via the CS (^), indicating partial unroofing. *, left superior vena cava; ^, coronary sinus; LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle; Ao, aorta; MPA, main pulmonary artery
