Operative profile and postoperative outcomes
Hospital mortality was comparable (n= 1, 1.4% and n=1, 0.4%, P=.43) in
BC and DNC groups respectively. Similarly, postoperative complications
including myocardial infarction, stroke, ECMO, and infections were not
significantly different between the two groups. However, the duration of
CPB (178 ± 60 vs. 150 ± 51, P<0.001) and cross clamp (143 ± 60
vs. 118 ± 42, P<0.001) were significantly lower in the DNC
group. Likewise, the volume of cardioplegia and the number cardioplegia
doses were significantly lower in the DNC group. Operative and
postoperative profiles are detailed in Table 2 .
The duration of inotropic support was significantly lower in the DNC
group, dobutamine (26.6 ± 19.3 vs. 21 ± 13.3, P=.02) and norepinephrine
(12 (3-29) vs. 7 (2-20), P=.02) in BC and DNC, respectively
(Supplemental Table S2 ).
