Femoral venous stasis index predicts elevated right atrial pressure and mortality in pulmonary hypertension.

ABSTRACT:

Background

Elevated right atrial pressure (RAP) is associated with poor prognosis regarding 1-year mortality in pulmonary hypertension (PH) patients. Unfortunately, there is currently no reliable non-invasive technique for estimating RAP in PH patients. Recently, femoral venous stasis index (FVSI) has been described as highly correlated with RAP in PH patients. Our main goal was to confirm the diagnostic accuracy of FVSI for estimating RAP.

Methods

In this prospective study, we included 101 patients with suspected or known PH undergoing right heart catheterisation for 18 months.

Results

FVSI was highly correlated with RAP (r_s=0.77, p<0.001). With a cut-off of 0.18, FVSI can exclude RAP >8 mmHg with 89% sensitivity (area under the receiver operating characte
