TAVR in Patients with Classical Low Flow, Low Gradient

TAVR in Patients with Classical Low Flow, Low Gradient

Classical symptomatic low-flow, low-gradient (LFLG) severe aortic stenosis is associated with low survival rates at 3 years (<50%). However, in the medium term and with surgery, those rates improve (although mortality rates are 6%-30%, depending on the series). In patients without contractile reserve, surgical mortality is higher. Patient evolution in TAVR is still mostly unclear.

Which Low-Flow, Low-Gradient Patients Benefit from Valve Replacement?

A mean gradient ≥40 mmHg, an aortic valve area ≤1 cm², or a combination of both, during dobutamine stress echocardiography, correctly qualifies as severe aortic stenosis in about half of all patients. The other half consists in cases of pseudo-severe aortic stenosis. In turn, a projected aortic valve area ≤1 cm² is a much better indicator than the

TAVR in Low-Flow Low-Gradient Aortic Stenosis and Severe Impairment of Systolic Function

Patients with low-flow, low-gradient severe symptomatic aortic stenosis associated with severe impairment of the left ventricular systolic function have shown acceptable outcomes after transcatheter aortic valve replacement (TAVR), according to the multicenter TOPAS-TAVI registry, which demonstrated a relatively low 30-day mortality rate.   Considering the very high risk presented by this population involved, a 30-day
