Key result
Annual hospital TAVR volume did not predict inhospital mortality (OR 1.00; 95% CI 0.99-1.00; p=0.111) or morbidity (OR 1.00; 95% CI 0.99-1.00; p=0.947).
Why the study?
Does hospital TAVR volume predict inhospital mortality or morbidity in patients undergoing TAVR?
Observational (n=7,635)
Yes
Does hospital TAVR volume predict inhospital mortality or morbidity in patients undergoing TAVR?
Odds Ratio: 1 (95% CI 0.99–1)
p-value: p=0.111
In the early commercialization era, TAVR demonstrated acceptable short-term safety with an inhospital mortality of 5.0%, and outcomes were not significantly predicted by hospital procedural volume.
No takes yet. Share an insight, caveat, or question.
No volume-outcome link seen in 2012 TAVR data; supports acceptable safety but leaves thresholds open for prospective validation.
Biasi et al. (2015) conducted an observational in Transcatheter aortic valve replacement (n=7,635). Annual hospital TAVR volume was evaluated on Inhospital mortality (OR 1.00, 95% CI 0.99-1.00, p=0.111). Annual hospital TAVR volume did not predict inhospital mortality (OR 1.00; 95% CI 0.99-1.00; p=0.111) or morbidity (OR 1.00; 95% CI 0.99-1.00; p=0.947).
