There are around 18 different types of CHD recognized with several variations. CHD awareness week is observed every year from February 7-14 when awareness and education are provided for people. This is considered one of the most common types of birth defects and the leading cause of infant death in their first year of life.<\/p>\n<p id=\"2\">Although the exact cause of heart defects aren\u2019t known, it is presumed to be genetic and is associated with a combination of multiple genetic and environmental factors.

As the result, the blood may flow where it shouldn\u2019t and with less than normal amount of oxygen which could lead to congestive heart failure. There are two types of AVSD; complete AVSD and partial or incomplete AVSD. In a complete AVSD, there is a large hole in the middle of the heart allowing the blood to flow between all four chambers of the heart. A complete AVSD can occur when the valve fails to separate into the tricuspid and <span id=\"urn:enhancement-2d226773-0648-48a7-9560-47ee99e03d9d\" class=\"textannotation disambiguated wl-thing\" itemid=\"https:\/\/data.wordlift.io\/wl1503301\/entity\/mitral\">mitral<\/span> value during pregnancy.

The treatment is based on improving the obstruction and leak although the valve cannot be made normal.<\/p>\n<p><strong>Identifying CHD in the <span id=\"urn:enhancement-ddf09f36-bb79-4b96-ab6e-b47ec44cd869\" class=\"textannotation disambiguated wl-thing\" itemid=\"https:\/\/data.wordlift.io\/wl1503301\/entity\/fetus\">Fetus<\/span><\/strong><\/p>\n<p id=\"4\">Identifying the heart defect in the <span id=\"urn:enhancement-b48ff215-7a8b-46cc-bc55-f0d39bafb2a4\" class=\"textannotation disambiguated wl-thing\" itemid=\"https:\/\/data.wordlift.io\/wl1503301\/entity\/fetus\">fetus<\/span> presents important implications such as pregnancy management and diagnosis of abnormalities in other organs.

Also, there is a wide range of fetal heart rates, the normal ranges from 120 to 160 but could also be as low as 90 without concern.
