Key result
Miniaturized CPB significantly reduced the inflammatory response compared to standard CPB in aortic valve surgery, with lower post-CPB levels of elastase (116 vs 265 ng/ml, P=0.01).
Why the study?

p-value: p=0.01
Miniaturized CPB circuits attenuate the systemic inflammatory response compared to standard circuits during aortic valve replacement.
Bical et al. (2006) conducted an RCT in singular aortic valve replacement (n=40). Miniaturized CPB circuit vs. Standard CPB circuit was evaluated on Systemic inflammatory response (neutrophil elastase) (p=0.01). Miniaturized CPB significantly reduced the inflammatory response compared to standard CPB in aortic valve surgery, with lower post-CPB levels of elastase (116 vs 265 ng/ml, P=0.01).
