Relationships between the individual echocardiographic parameters used in the 2016 ASE algorithm and the invasively measured LV filling pressure

Parameter	Invasive LV pre-A filling pressure
Parameter	r	P
E/A ratio	0.34	.001
E/e′ ratio	0.40	.0001
LAVi	0.23	.029
Peak TR velocity^*	0.29	.030

TR, Tricuspid regurgitation.

See text for details.

Peak TR velocity was available in 54 of 90 patients (60%); this included similar numbers of patients with normal (29 of 54) versus elevated (25 of 54) LV filling pressure. Peak TR velocity could not be measured in 36 of 90 patients (40%), 78% of whom had normal LVEFs.
