Table 2. Embolic Grade on Transesophageal Echocardiography during Total Knee Arthroplasty
*= significant difference between groups in the frequency of appearance of the echogenic materials (P < 0.05).
Grade 0 = no emboli; grade 1 = a few fine emboli; grade 2 = a cascade of fine emboli or embolic masses with diameter of < 5 mm and the right atrium opacified with echogenic materials; grade 3 = fine emboli mixed with large embolic masses with a diameter of > 5 mm or serpentine emboli.
