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).

echocardiographic views. Schematic echocardiographic cross sections of
the mitral valve as described in the American Society of
Echocardiography and Society of Cardiovascular Anesthesiologists

echocardiographic examinations. Adapted from Shanewise et al., 1999.
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.
