On an ordinary afternoon, Mrs. Li sat in the waiting room of the maternity hospital, holding her husband's hand tightly. She was a little nervous because she was about to have not just a routine pregnancy check-up, but a specialized fetal heart ultrasound. Mrs. Lee, a 35-year-old first-time woman, has had a smooth pregnancy so far, but due to her age, doctors recommended this test to rule out potential fetal heart problems.
The results of the examination unexpectedly revealed that the fetus had a slight structural abnormality in the heart. While this was a huge blow to Mrs. Lee and her family, the discovery also allowed her to be fully prepared before the birth of her child. Thanks to early detection and intervention, Mrs. Lee's child received the necessary treatment after birth and is now a lively and healthy little baby.
This story is a testament to the importance of fetal cardiac ultrasound. It's not just a routine, but a critical medical procedure that can prevent serious birth defects.
The Basics of Fetal Cardiac Ultrasound: Guarding the Heartbeat of the Future
Fetal echocardiography, also known as fetal heart ultrasound, is a diagnostic tool that uses ultrasound technology to examine the structure and function of the heart of an unborn baby. This test is usually done in the second trimester of pregnancy, around 18 to 24 weeks, when the baby's heart is mature enough to be seen in detail.
The purpose of the inspection
The main purpose of fetal ultrasound is to detect and diagnose possible structural abnormalities of the heart. These abnormalities can be the presence of holes between the ventricles of the heart, problems with the heart valves, or abnormalities in the size and shape of the heart. With early diagnosis, it is possible to plan a treatment strategy to be carried out immediately after birth or, in some cases, even to intervene while the fetus is still in the womb.
The importance of checks
According to medical research, heart malformations are one of the most common birth defects, accounting for about 1% of all birth defects. The use of fetal heart rate ultrasound has greatly improved the diagnosis rate of these problems, allowing families and medical teams to better prepare for the arrival of their children. In some cases, undiagnosed and untreated, fetal heart problems can lead to immediate health risks and even long-term quality of life consequences for the baby.
Techniques and methods
During fetal heart rate ultrasound, the pregnant mother lies on an examination table and uses a harmless ultrasound gel and a probe to obtain images of the fetal heart. A professional doctor or sonographer will look closely at these images and analyze the baby's heart structure to see if everything is normal.
Cardiac monitoring: why fetal heart sound is indispensable
Fetal heart ultrasound (fetal heart rate ultrasound) is one of the most critical tests during pregnancy, and its importance is not only due to the early detection of potential heart malformations, but also to the ability to take appropriate medical measures in time to reduce complications after birth. Every year, about 1% of newborns worldwide have some form of heart defect, making heart problems one of the most common birth defects. Fetal heart echo can identify these problems as early as the first trimester and provide necessary medical intervention for the mother and fetus.
Fetal heart echo is usually performed between 18 and 24 weeks of pregnancy, because during this time, the fetus's heart structure has developed enough to be examined in detail. With this ultrasound, doctors are able to take a detailed look at the baby's heart structures, including the ventricles, atria, heart valves, and their functions. If abnormalities are found, this opens up the possibility of early intervention, such as surgery immediately after birth, or special monitoring measures during pregnancy.
In addition, fetal heart rate ultrasound also has important psychological effects on pregnant women and families. Knowing the health of the fetus can greatly reduce the psychological stress of the pregnant woman, and it also helps the family to better prepare for possible medical conditions in the future. Therefore, although fetal heart rate ultrasound does not prevent heart defects from occurring, it is a key part of preventing these conditions from leading to serious consequences.
Special surveillance: which pregnant women need enhanced cardiac monitoring
Although fetal heart rate ultrasound is important for all pregnant women, it is especially important for pregnant women in certain high-risk groups. Here are some of the situations in which a fetal heart rate ultrasound should be done in particular:
Family genetic history: If you have a family history of congenital heart disease, your baby is at increased risk of having the same condition. In such cases, doctors usually recommend earlier and more frequent fetal heart rate ultrasonography.
Older mothers: Older mothers (usually over the age of 35) have a higher chance of developing chromosomal abnormalities, and some chromosomal problems are related to heart malformations.
Poor lifestyle habits: Pregnant women who smoke, drink alcohol and use certain drugs have an increased risk of heart problems in their babies. These pregnant women should undergo a detailed fetal heart rate examination before and during pregnancy.
Chronic health problems: Pregnant women with abnormal glucose metabolism (diabetes) or high blood pressure in the systemic arteries (hypertension) may develop heart disease in their babies due to maternal conditions. In these cases, your doctor may recommend more rigorous monitoring.
By identifying and monitoring these specific conditions, fetal heart ultrasound can help prevent heart defects from having a greater impact on maternal and newborn health. During fetal heart rate overtime, doctors evaluate several parameters to ensure accurate diagnostic information is obtained so that the best medical decisions can be made.
In conclusion, fetal heart rate ultrasound is not only a part of pregnancy check-ups, it plays an irreplaceable role in preventing, diagnosing and preparing for heart defects. For this reason, it is important to strengthen the monitoring of specific high-risk groups to ensure that every mother and her baby get the best possible start.
