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 ).
