The shape of the right ventricular Doppler envelope (FVE(RVOT)) predicts hemodynamics and correlates with severe pulmonary vascular disease and right heart dysfunction.
Does the shape of the right ventricular Doppler envelope predict hemodynamics and right heart function in patients with pulmonary hypertension?
Visual inspection of the right ventricular Doppler envelope shape, specifically mid-systolic notching, can predict severe pulmonary vascular disease and right heart dysfunction in pulmonary hypertension.
Visual inspection of the shape of the FVE(RVOT) provides insight into the hemodynamic basis of PH in a referral PH cohort. MSN is associated with the most severe pulmonary vascular disease and right heart dysfunction.
Arkles et al. (2010) studied this question. The shape of the right ventricular Doppler envelope (FVE(RVOT)) predicts hemodynamics and correlates with severe pulmonary vascular disease and right heart dysfunction.
