Text: In patients with functional MR, maximal regurgitant jet area (JA), the vena contracta (VC) width, and the proximal isovelocity surface area (PISA) radius were significantly smaller at a low BIS than at a high BIS (JA, 2. 4 cm (2), 1. 9-4. 7, v 5. 0 cm (2), 3. 4-6. 7, p < 0. 001 ; VC width, 2. 7 1. 6 v 4. 2 1. 4 mm, p < 0. 001 ; PISA radius, 3. 3 2. 3 v 5. 6 2. 4 mm, p < 0. 001).
