Right Ventricular Outflow Tract Doppler Notching Predicts Survival in Patients with Pulmonary Hypertension and Heart Failure with Preserved Ejection Fraction

Pulmonary hypertension (PH) in the setting of left heart disease (PH-LHD) is the most common cause of PH in the general population, with a prevalence of up to 80% and is associated with high morbidity and mortality. We have previously demonstrated the utility of right ventricular outflow tract (RVOT) Doppler notching as a composite marker of pulmonary vascular disease (PVD) in patients with PH-associated with heart failure with preserved ejection fraction (HFpEF). Our study examines the ability of RVOT Doppler notching to predict survival in patients with PH-HFpEF.
