Clinical Trial Summary

Hyperoxemia can produce various complications including oxidative stress and myocardial injury. We hypothesized that the normoxic group would have lower myocardial injury compared to hyperoxic group after transcatheter aortic valve replacement.

Description:

Hyperoxemia can produce various complications, such as excessive oxidative stress, hyperoxia-induced vasoconstriction, increased perfusion heterogeneity, and resultant myocardial injury. Previous studies have been observed higher mortality in patient group maintained with supranormal oxygenation after resuscitation from cardiac arrest. However, the effect of hyperoxia vs. normoxia on myocardial injury during transcatheter aortic valve replacement (TAVR) has not been well investigated. We hypothesized that the normoxic group would have lower myocardial injury compared to hyperoxic group after TAVR.
