Risk profile and outcomes of aortic valve replacement in octogenarians

Figure 1 Flow chart of study enrollment. The 9 patients for whom notes are unavailable: 5/9 were male (56%); Mortality-Nil; Age: mean (SD) = 83.9 (3.7), range = 80.2-92.1; EuroSCORE: Median (interquartile range) = 9 (8-10), range = 7 to 11. AVR: Aortic valve replacement; MVR: Mitral valve replacement; VSD: Ventricular septal defect.

Figure 2 Logistic EuroSCORE, 30- and 90-d mortality by quartiles of Logistic EuroSCORE. Black capped spikes represent median and quartiles of Logistic EuroSCORE (LES) (LES predicted overall mortality for quartiles: 7.8, 9.8, 13.6, 26.5); gray capped spikes represent the percent 30-d (solid) and 90-d (dashed) mortality, with 95% CIs. Tests for trend: 30-d mortality, P = 0.001; 90-d mortality, P = 0.005. CI: Confidence interval.

Figure 3 Logistic EuroSCORE, 30-d and 90-d mortality by operative era. Black capped spikes represent median and quartiles of Logistic EuroSCORE; gray capped spikes represent percent 30-d (solid) and 90-d (dashed) mortality, with 95% CIs. Bars represent the number of aortic valve replacement procedures. Tests for trend: 30-d mortality, P = 0.49; 90-d mortality, P = 0.34.
