Figure 2. Comparison of NICaS parameters over time according to mean gradient and ejection fraction.

Figure 2

A, NICaS parameters over time stratified by a low transvalvular mean gradient. A low mean gradient was defined as <40 mm Hg. B, NICaS parameters over time stratified by a reduced ejection fraction. Reduced ejection fraction was defined as ejection fraction <40%. CO indicates cardiac output; EF, ejection fraction; SV, stroke volume; TAVI, transcatheter aortic valve replacement; and TPR, total peripheral resistance.
