The 3-step PSP comprised the planning of mediastinal re-entry, cannulation for cardiopulmonary bypass (CPB) and the main procedure, using standard 3-dimensional videos.

The 3-step PSP (n\u2009=\u200914) and the conventional planning (n\u2009=\u200968) groups were compared. There were no statistically significant differences in the preoperative characteristics. Differences were observed in the total operative time (P\u2009=\u20090.009), skin incision to CPB (P\u2009=\u20090.034) and cross-clamp times (74\u2009\u00b1\u200933 vs 108\u2009\u00b1\u200947\u2009min; P\u2009=\u20090.006), favouring the 3-step PSP group. Eight matched pairs were compared showing differences in the total operative time (263\u2009\u00b1\u200944 vs 360\u2009\u00b1\u200966\u2009min; P\u2009=\u20090.008), CPB time (123\u2009\u00b1\u200934
