Maternal cigarette smoking in the first trimester was associated with a 20 to 70 percent greater likelihood that a baby would be born with certain types of congenital heart defects, according to a study by the Centers for Disease Control and Prevention.
Congenital heart defects are the most common type of birth defects, contributing to approximately 30 percent of infant deaths from birth defects annually.
The common defects are a communicating gap between both the upper chambers of heart (Atrial septal defect) called atrias; and outflow obstruction from the right side of heart to the lungs.
Quitting smoking is the single most important thing a woman can do to improve her health as well as the health of her baby. Successfully stopping smoking during pregnancy also lowers the chances of pregnancy complications such as preterm delivery and low birth weight baby.
Researchers in a study found that right ventricular outflow tract obstructions affect approximately 2,500 infants per year and atrial septal defects affect approximately 5,600 infants per year in the United States.
