Double Outlet Right Ventricle Repair

Double Outlet Right Ventricle (DORV) is a rare congenital heart defect in which both the aorta and pulmonary artery arise from the right ventricle instead of the aorta arising from the left ventricle and the pulmonary artery from the right. In a normal heart, the right ventricle pumps blood into the lungs via the pulmonary artery, while the left ventricle pumps oxygenated blood into the body via the aorta. In DORV, this normal separation of blood flow is disrupted, causing oxygen-poor blood to be circulated throughout the body and leading to serious complications.

DORV is a congenital condition, meaning it is present at birth. The exact cause of the defect is not always known, but there are several factors that may contribute to its development:

Causes of DORV: Genetic Factors: In some cases, DORV may be linked to genetic syndromes, such as DiGeorge syndrome, which causes developmental issues that affect the heart.

Chromosomal Abnormalities: Chromosomal disorders like Down syndrome may increase the risk of congenital heart defects, including DORV.

Environmental Factors: Certain environmental factors during pregnancy, such as maternal infections, smoking, or drug use, may contribute to the development of congenital heart defects, though these factors are less well understood.

Multifactorial Causes: Most cases of DORV likely arise due to a combination of genetic and environmental factors, though the precise cause remains unclear for many individuals.

While DORV occurs due to developmental issues during fetal growth, there are no specific lifestyle habits or preventive measures that can guarantee its prevention. However, early detection through prenatal ultrasounds or post-birth screening can help manage the condition effectively.

The symptoms of DORV vary depending on the severity of the defect and associated complications. In many cases, symptoms become apparent soon after birth, as the baby may show signs of poor oxygenation or heart strain.
