Right Pulmonary Artery Regurgitation (RPAR) is a condition where blood flows backward from the pulmonary artery into the right ventricle of the heart. This article aims to simplify the complexities surrounding RPAR, providing clear explanations of its causes, symptoms, diagnostic procedures, and available treatments.
Causes of Right Pulmonary Artery Regurgitation:
- Congenital Heart Defects: Some individuals are born with abnormalities in their heart structure that can lead to RPAR.
- Pulmonary Hypertension: High blood pressure in the arteries of the lungs can strain the right ventricle, causing RPAR.
- Pulmonary Valve Stenosis: Narrowing of the pulmonary valve can disrupt blood flow and contribute to RPAR.
- Infective Endocarditis: Bacterial infection of the heart’s inner lining can damage the pulmonary valve, leading to RPAR.
- Rheumatic Heart Disease: This inflammatory condition can affect the valves of the heart, including the pulmonary valve.
- Trauma: Injury to the chest area can damage the pulmonary artery or its valves, causing regurgitation.
- Connective Tissue Disorders: Conditions like Marfan syndrome can weaken the connective tissues in the heart, increasing the risk of RPAR.
