Statistical Analysis
Descriptive statistics (mean (SD), median [interquartile range], and %(N), as appropriate), were presented for MV complexity scores, patient demographics, and comorbidities. Kappa values were reported for the agreement of TEE scores and surgical scores. McNemar’s tests were used to test the homogeneity of the marginal probabilities of different scoring categories. All statistical analyses were performed using SAS, version 9.4.
