Table 4. In-hospital mortality and hospital length of stay analyzed by change in tricuspid regurgitation severity after transcatheter aortic valve replacement.

Variable	Change in tricuspid regurgitation severity			P value
Variable	Remained mild^a (N=115)	Improved^b (N=30)	No change/worsened^c (N=29)	P value
All-cause mortality	4/115 (3.5)	3/30 (10.0)	6/28 (21.4)	0.002
Cardiovascular mortality	2/115(1.7)	2/30 (6.7)	4/29 (13.8)	0.005
Median length of hospital stay (days, IQR)	5 [3–10]	4.5 [4–8]	7 [4–20]	0.241

Variables presented as number (percentage), unless otherwise noted. ^a, patients with trace/mild tricuspid regurgitation before TAVR and after TAVR; ^b, patients with moderate or severe tricuspid regurgitation that improved by 1 or more grades after TAVR; ^c, patients with baseline and post-TAVR persistent moderate or severe tricuspid regurgitation. IQR, interquartile range; TAVR, transcatheter aortic valve replacement.
