CHSS Score Critical AS

The current iteration of the CHSS Critical Aortic Stenosis has been inactivated pending an updated analysis.

In a recent evaluation of the calculator using a more recent patient cohort from the CHSS Critical Left Heart Obstruction Cohort, we found that the parametric models underlying the calculator significantly underestimated survival in patients with critical aortic stenosis with a biventricular or univentricular repair. Further, we found that management discordant with that suggested by the calculator was no longer associated with mortality. Thus, we have concluded that the calculator does not predict optimal management in contemporary critical aortic stenosis patients.
