Fig. 2From: Enumeration of circulating endothelial cell frequency as a diagnostic marker in aortic valve surgery - a flow cytometric approachCardiac enzymes peri-operatively: CK. Serial time course of CK levels in patients operated using CAVR or TAVI technique. CK levels were comparable pre-operatively and significantly higher 1 h and 1 d after surgery in the CAVR group compared to the TAVI group. This difference did not reach statistical significance 5 d after surgery (*p < 0.05, **p < 0.001)Back to article page
