Popis:	Fixed right ventricular outflow obstruction, such as pulmonary valve stenosis, causes a systolic pressure difference between the right ventricle (RV) and pulmonary artery (PA). This is an established confounder of PA pressure estimation using tricuspid regurgitation flow velocity and must be
