Values are mmHg unless indicated. Study by Villa is represented by “a” and “b” as Villa chose to compare cohorts solely by valve type (S vs. M, L, XL). *, represents the study by Shrestha 2013. Echo, echocardiography; EOA, effective orifice area; EOAi, indexed effective orifice area; NR, not reported.
