10 Causes of Pulmonary Arterial Hypertension

Role of Heart Abnormalities in the Development of Pulmonary Material Hypertension

Heart abnormalities are present at birth and significantly contribute to the development of pulmonary material hypertension. These abnormalities, also known as congenital heart disorders or defects, may require surgical intervention in infants. Although heart surgery in babies is challenging for everyone involved, it is crucial to address these abnormalities to prevent potential complications. If left untreated, heart defects can lead to various issues, including increased pulmonary vascular resistance and obstructive arteriopathy, in addition to pulmonary arterial hypertension (PAH).


Left-Sided Heart Disease and Pulmonary Arterial Hypertension

When the lower left heart chamber, known as the left ventricle, fails to function properly, it can lead to a condition called pulmonary arterial hypertension, which falls under group 2 of causes. Left-sided heart disease is the primary cause of this type of pulmonary hypertension. Conditions in this category include mitral valve disease and aortic valve disease. The mitral valve is responsible for regulating blood flow between the heart’s upper and lower chambers, while the aortic valve connects the main heart chamber to the major artery. These issues can either be congenital or acquired through disease, but fortunately, surgical interventions are available for repair.
