Original Article Arq Bras Cardiol. 2018; 111(2):193-202 Miyazaki et al Videodensitometry assessment of AR to guide TAVI Video 1 – Videodensitometric assessment of aortic regurgitation before and after balloon post-dilatation. Left panel shows VD-AR assessment before BPD (VD‑AR = 20%). Right panel shows VD-AR assessment after BPD (VD-AR = 6%). Figure 3 – Serial changes of the Videodensitometric-AR. Individual serial changes before and after balloon post-dilatation are shown in this figure. In patients with VD‑AR > 17%, 7 deaths (34%) occurred, whereas in patients with VD-AR ≤ 17%, 8 deaths (19%) were observed. % 60 50 40 30 20 10 0 17% Videodensitometric-AR All cause death (4 years) All cause death (4 years) 7/19 (34%) 8/42 (19%) * p < 0.001 Before BPD After BPD Videodensitometric-AR (Median[IQR]) Videodensitometric-AR > 17%, n (%) Videodensitometric-AR ≤ 17%, n (%) Before BPD (n = 61) After BPD (n = 61) 24.0[18.0-30.5] 12.0[5.5-19.0] 47(77%) 14(23%) 19(31%) 42(69%) and ranged from 0.0% to 22.8% in patients with a significant improvement of AR, and 13.8[3.3,16.5], ranging -29.0% to 19.3% in those with no change or a significant deterioration of AR.
