Purpose. To test the feasibility of performing coronary
artery bypass grafts (CABG) with a closed extra-corporeal circuit
(ECC).
Material and Methods. Sixty-one patients underwent CABG.
ECC was performed in normothermia, and normovolemia using cell
saver as an aspiration. High risk patients were operated with
partial bypass and a beating heart. When cross clamping was done,
warm blood cardioplegia was performed antegrade.
Results. 30 patients were operated with partial ECC. Five
and three patients had preoperative inotropic support, and intra-aortic
balloon pump. Mean ejection fraction (EF) was 38,2% ± 1,8. Mean
NYHA was 3,4 ± 1,4. One patient sustained a perioperative myocardial
infarction (1,6%). Mean ECC time was 62,1 ± 22,7 min.
Mean preoperative and postoperative hematocrit were respectively
35,4 %± 5,3, and 31,3% ± 5.
Follow up at three months was complete. No mortality occurred;
mean EF was 45,6% ± 2,3, and mean NYHA was 1,3 ± 0,6.
Conclusions. Coronary artery bypass graft can be performed
using a closed ECC circuit, with normothermia and normovolemia.
