Cor pulmonale?,”Cor pulmonale refers to impaired function of the RV caused by pulmonary hypertension that occurs due to underlying diseases of the lungs (COPD, interstitial lung disease (ILD)), pulmonary vasculature (idiopathic pulmonary arterial hypertension), or obstructive sleep apnea. By convention, RV dysfunction due to Left heart disease or congenital heart disease is not considered cor pulmonale.
