TABLE 4.

Multivariable Cox regression to identify the variables associated with the combined endpoint in patients with atrial and ventricular secondary tricuspid regurgitation.

		HR (CI 95%)	P–value
V-STR patients	TR grade (severe versus moderate)	2.9 (1.4–6.3)	0.005
	Right ventricular free wall longitudinal strain (RVFWLS, –%)	0.93 (0.85–0.98)	0.009
	RV ejection fraction (%)	0.97 (0.94–0.99)	0.044
	3D max RAV index (ml/m2)	1.01 (0.99–1.02)	0.366
A-STR patients	3D-right atrial maximum volume (ml/m2)	1.01 (0.99–1.07)	0.34
	TR grade severe versus moderate	5.8 (1.4–25)	0.02

3D, three-dimensional; A-STR, atrial secondary tricuspid regurgitation; RA, right atrium; RV, right ventricle; RVFWLS, right ventricle free wall longitudinal strain; RVGLS, right ventricle global longitudinal strain; SPAP, Systolic pulmonary arterial pressure; TA, tricuspid annulus; TR, tricuspid regurgitation; TAPSE, tricuspid annular plane systolic excursion; V-STR, ventricular secondary tricuspid regurgitation.
