Right Ventricular Outflow Doppler Envelope: Insight into Pulmonary Artery Disease Severity in Two Cardiac Centers in Baghdad

Abstract

Background: Pulmonary artery hypertension is described as a group of diseases characterized by a progressive increase in pulmonary vascular load resulting in a marked increase in pulmonary artery pressure (PAP). While the reference approach and "gold standard" for quantifying pulmonary artery, pressure is direct pressure measurement with proper cardiac catheterization. Additionally, echocardiography provides the advantage of non-invasively and precision and is widely used to measure systolic pulmonary artery strain.
