BACKGROUND: Late tamponade is a rare cause of morbidity and mortality after @entity299 . We describe our recent experience with this entity. METHODS: This is a single institution, procedure-matched, retrospective review of @entity1 undergoing pericardiocentesis more than 7 days after cardiac operation, during a 7-year period. RESULTS: Pericardiocentesis for delayed tamponade was performed in 43 of 9,612 @entity1 . Although isolated valve operation accounted for 17% of all @entity1 overall, 76% of @entity1 undergoing pericardiocentesis (33 of 43) had undergone isolated valve operation. The average age in this group was 58 years, compared to an average of 68 years in all @entity1 . @entity1 presented with tamponade an average of 18 days after operation. Positive predictors included elevated @entity556 time on presentation. Of the @entity1 cohort 75% presented with @entity1353 , 61% with inability to diurese, and 61% with @entity551 . Echocardiography detected effusions in all @entity1 , but specific echocardiographic signs of tamponade were present in only 30%. Of the @entity1 , 97% were successfully treated by pericardiocentesis. All were safely restarted on @entity1229 . One @entity1 required pericardial window. CONCLUSIONS: Delayed @entity2293 is more common after isolated valve operation, as opposed to coronary artery bypass grafting and valve/coronary artery bypass grafting. It tends to occur in the third postoperative week in younger @entity1 who are aggressively anticoagulated. Pericardiocentesis with catheter placement is highly effective, and @entity1 can be reanticoagulated safely. This series underestimates the incidence of late tamponade, as some @entity1 may present to outside facilities. The diagnosis is aided by a high degree of suspicion.
