Background and aims of the study: While the hemostatic effect of aprot
inin for patients undergoing reoperative coronary bypass is well estab
lished, it remains unclear whether these effects extend to patients un
dergoing reoperative valvular surgery. Methods: We examined our experi
ence with 85 consecutive patients undergoing isolated reoperative valv
ular surgery with and without use of perioperative aprotinin in order
to investigate differences in perioperative blood use, blood loss, ble
eding complications, mortality and incidence of myocardial injury. Res
ults: Aprotinin recipients benefited from a significant reduction in b
leeding complications, and a decrease in perioperative and in-hospital
mortalities as compared with untreated patients. Anaphylactic reactio
ns and clinically significant thromboembolic events were not observed.
There was no difference in the incidence of renal dysfunction or myoc
ardial injury among aprotinin-treated and untreated groups. Conclusion
s: Our results indicate that aprotinin therapy can be safely administe
red to patients undergoing reoperative valvular surgery. No increased
incidence of anaphylactic reactions, renal dysfunction or perioperativ
e myocardial injury was noted. The observed reductions in bleeding com
plications and perioperative and in-hospital mortality strongly warran
t the evaluation of aprotinin for reoperative valvular surgery in a pr
ospective fashion.
