Pulmonary Venous Hypertension- An On Going Quest for Treatment: Is PDE5 Inhibition the Right Solution?
Pulmonary venous hypertension is pulmonary hypertension resulting from elevated left sided filling pressures. This may result from chronic elevation of left atrial pressures from heart failure; either heart failure with reduced ejection fraction (HFrEF) or heart failure with preserved ejection fraction (HFpEF) or from valvular heart disease. This is classified as Group 2 pulmonary hypertension in the Dana point classification. Pulmonary hypertension due to left heart disease is defined as mean pulmonary arterial pressure (mPAP) greater than or equal to 25 mm Hg, pulmonary capillary wedge pressure (PCWP) of greater than or equal to 15 mm Hg and pulmonary vascular resistance (PVR) greater than 3WU.
