Predicted PPM status was determined using mean reference effective orifice area indexed to total body surface (iEOA), without considering reference standard deviations.

After surgery, the actual postoperative iEOA was measured: 53 (25.9%) did not have PPM, 73 had moderate PPM (35.6%), and 79 had severe PPM (38.5%). Predicted PPM identified the presence of hemodynamically significant actual postoperative PPM (OR\u00a0=\u00a02.56; 95%CI 1.30\u20135.05; <jats:italic>P<\/jats:italic>\u00a0=\u00a0.006), though not its degree of severity.
