Cor pulmonale is a condition that occurs when the right ventricle of your heart cannot pump properly. The right side of your heart pumps blood from your body into your lungs to get oxygen. Cor pulmonale is caused by pulmonary hypertension (PH). PH is high blood pressure in the arteries of your lungs. Blood cannot flow through your lungs and backs up in the right ventricle of your heart. As the right ventricle tries to pump blood properly, it becomes thickened and deformed. Cor pulmonale can become life-threatening.
