How big is your heart?
The size of your heart is about the same size as your fist. The size proportion of these two body parts starts from infancy and far into adulthood. The heart is the body engine that keeps one going. Exercise, a clean lifestyle, a healthy diet and weight will go a long way in keeping your heart fit. However, there are cases when the heart is defective at birth, a condition known as a congenital heart defect.
What is a Congenital Heart Defect?
A congenital heart defect is structural flaw in the heart that is present at birth. It may cause the blood flow to slow down, go in the wrong direction, go to the wrong place, or it may block the flow completely. Sometimes, they are referred to as cyanotic heart disease or congenital cardiovascular malformations.
Common Congenital Heart Defects
Heart defects are the most common of abnormalities at birth. About 35,000 infants are born with it each year in the United States. The defect ranges from mild, requiring little or no treatment, to severe which could potentially put an infant’s life at risk. They account for majority of birth defect-related fatalities.
Examples of non-severe congenital heart diseases are Atrial Septal Defect (ASD), Patent Ductus Arteriosus and narrowed valves. Tetralogy of Fallot is the most common of complex heart defects. It is a condition wherein not enough blood is able to reach the lungs to get oxygen, and oxygen-poor blood flows to the body.
Causes
Heart defects can be caused by prenatal environmental as well as genetic factors. However, the actual cause could not determined in most instances. Alcohol consumption, nicotine and cocaine dependence during pregnancy could result to heart abnormalities. Other possible causes are medication, viral infections and chronic illnesses such as diabetes, phenylketonuria (PKU) and deficiency in the B vitamin folic acid. Heredity and genes likewise contributes to the development of heart defects.
Prevention
The first trimester of a mother’s pregnancy is critical. The heart, like some other body organs, starts to develop shortly after conception. Complications and abnormalities resulting to abnormalities in the heart are likely to occur.
During pregnancy, drug medication should not be taken without the doctor’s clearance. Many drugs contain chemicals or substances that could potentially harm the fetus. As an example, the U.S. Food and Drug Administration (FDA) had issued several health advisories on the potential benefits and risks of antidepressants during pregnancy. Based on FDA advisory, pregnant women who took Paxil were 1.5 to two times at risk of having babies with a congenital heart defect compared to those who took other antidepressants. The issue of pre-natal drug medication, like the Paxil birth defect, is one that should not to be cast aside by any pregnant woman.
