10 Causes of Pulmonary Arterial Hypertension

4. Left side heart disease

If a patient suffers a failure of the lower left heart chamber, which is the left ventricle, then it is considered to be pulmonary arterial hypertension caused by left-sided heart disease. This is considered to be in group 2 of causes. Left side heart failure is the most common cause of this kind of pulmonary hypertension. Diseases categorized in this group include mitral valve and aortic valve disease. Mitral valve is the valve that sits between the heart's upper and lower chambers; the aortic valve connects the main heart chamber and your major artery. These problems may be a defect at birth or come from disease, either way; they should be able to be repaired with surgery.
