Table 1. Mitral valve complexity score calculation, adapted from Anyanwu et al., 2016.
Total complexity score = sum of individual scores. Complexity strata: Simple = 1; Intermediate = 2 - 4; Complex ≥5.
Table 2: Agreement between TEE and Surgical Scores. Agreement was greater between surgical and TEE complexity scores when surgical complexity score was simple (1) or intermediate (2 – 4), versus complex (>5).

Figure 2: Percentage of agreement between surgical and TEE scores by surgical complexity score. Greater agreement between surgical and TEE scores is demonstrated for simple (surgical score = 1) and intermediate (surgical score = 2, 3, or 4) complexity mitral valve lesions.
Figure 3: Agreement between surgical and TEE score for each anatomical segment. Greatest agreement between surgical and TEE complexity score is demonstrated for P1, P2, P3 and A2 prolapse.
