The lengths of intensive care unit and hospital stays were significantly longer in the group that did not undergo posterior pericardiotomy compared to the group that did, both in the overall and in the propensity-matched cohorts. The occurrence of postoperative atrial fibrillation and stroke did not differ significantly between the two groups. The amount of pericardial drainage was not significantly lower in the group that underwent posterior pericardiotomy in the overall cohorts (<jats:italic>p<\/jats:italic>\u2009=\u20090.09), but the difference was significant in the propensity-matched cohorts (<jats:italic>p<\/jats:italic>\u2009=\u20090.04). The amount of mediastinal drainage was significantly lower in the group that underwent posterior pericardiotomy, both in the overall cohorts (&lt;\u20090.001) and in the propensity-matched cohort (&lt;\u20090.001).
