Good enough…isn't.

Mild PVR has been shown to increase all-cause and cardiovascular mortality after TAVR, especially in high surgical risk patients. Mechanistic and associative causes, as well imprecise ascertainment have been suggested as underlying etiologies of this association. Ongoing trials with newer valve technologies, broader patient inclusion and more systematic assessment of PVR may provide further insight into the prevalence, causality, and outcome of PVR.
