Fig 1 Kaplan-Meier curves according to the four perioperative early transmitral inflow velocity/early mitral annular tissue velocity (E/e′) ratio groups which were defined as preoperative and postoperative E/e′ ≤15 (low-low), preoperative E/e′ ≤15 but postoperative E/e′ >15 (low-high), preoperative E/e′ >15 but postoperative E/e′ ≤15 (high-low), and preoperative and postoperative E/e′ >15 (high-high).

Fig 2 Cubic spline function curve of hazard ratio according to (A) preoperative and (B) postoperative early transmitral inflow velocity/early mitral annular tissue velocity (E/e′) values as continuous variables. The dotted line indicates the 95% confidence interval.

Fig 3 Kaplan-Meier curves analysis according to preoperative and postoperative early transmitral inflow velocity/early mitral annular tissue velocity (E/e′) groups before and after propensity score matching. Preoperative E/e′ groups (A) before and (B) after matching. Postoperative E/e′ groups (C) before and (D) after matching.
