The estimated image shortening of the RAO projections with a projection angle equaling to 30° (RAO30), 45° (RAO45) and coronary sinus direction (RAOCS). The shortening rate distributions under different RAO projections are shown by plots. It can be figured out that RAOCS rendered less shortening (0.83 ± 0.84%) comparing to RAO30 (13.03 ± 7.56%) and RAO45 (3.93 ± 3.84%). *P < 0.0001. Mean ± SD as indicated
