Key result
Introducing a TAVI service was associated with a 37% increase in conventional AVR activity (p<0.001) and no significant change in crude mortality (2.1% vs 2.9%, p=0.48).
Why the study?
Does the introduction of a TAVI service impact the volume and outcomes of conventional aortic valve surgical activity?

May support TAVI programs to increase AVR volumes without mortality harm; leaves open causal effects and generalizability.

Does the introduction of a TAVI service impact the volume and outcomes of conventional aortic valve surgical activity?
Absolute Event Rate: 2.1% vs 2.9%
p-value: p=0.48
The introduction of a TAVI service was associated with a significant increase in conventional AVR surgical volume without adversely affecting surgical mortality.
Grant et al. (2010) conducted an observational in Aortic valve disease (n=865). Introduction of a TAVI service vs. 2 years before the introduction of a TAVI service was evaluated on Crude mortality rate (p=0.48). Introducing a TAVI service was associated with a 37% increase in conventional AVR activity (p<0.001) and no significant change in crude mortality (2.1% vs 2.9%, p=0.48).
