Repeat sternotomy after reconstruction of the pericardial sac with @entity3584 -preserved XXXX pericardium.

The risk of repeat sternotomy is higher than that of the initial sternotomy, especially if the pericardial sac was left open at the first intervention. In 200 consecutive @entity1 with a @entity2294 after open heart operations, the pericardium was closed with a @entity3584 -preserved @entity1641 pericardial patch. @entity1104 at reoperation were assessed in four groups of @entity1 on a scale of 6, ranging from 0 (no @entity1104 ) to 5 (calcified or ossified @entity1104 ). Group I comprised 13 @entity1 in whom the pericardium was left open at the first operation and an @entity1641 pericardial patch was implanted at reoperation. Group Ia included the first five Group I @entity1 who underwent reoperation less than 1 year (early reoperation) after the initial procedure. Group Ib included the other eight @entity1 of Group I, who underwent reoperation more than 1 year (late reoperation) after the first procedure. Group II comprised nine @entity1 who were reoperated on after reconstruction of the pericardial sac with a @entity3584 -preserved @entity1641 pericardial patch. After a mean follow-up of 20.2 months, the incidence of patch-related complications was 1%. Statistical analysis shows less severe @entity1104 on reoperation in Group II @entity1 ( @entity2294 patched) than in Group I @entity1 ( @entity2294 left open): mean grade of @entity1104 1.6 +/- 0.9 (Group II) versus 3.2 +/- 0.6 (Group I), p less than 0.001. @entity1104 with the pericardium left open were similar in @entity1 having early and late reoperations: mean grade of @entity1104 3.0 +/- 0.7 (Group Ia) versus 3.4 +/- 0.5 (Group Ib), no significant difference. Therefore, the @entity3584 -preserved @entity1641 pericardial patch can be considered a suitable material for primary closure of the pericardial sac in @entity1 with inadequate autologous pericardium.
