What is congenital heart disease

• Home
• Information
• Articles

(CHP) are anatomical changes in the structures of the heart. CHD occurs in 8-10 out of 1000 children. In recent years, this figure has been growing (mainly due to improved diagnosis and, accordingly, an increase in the frequency of cases of CHD recognition).

What are the causes of UPU?

The formation of the heart occurs at 2-8 weeks of gestation, and it is during this period that defects develop. Most often, the defect is the result of an accidental violation of the development of the heart in the fetus, so a child with a defect can be born in any family. Sometimes CHD are combined with malformations of other organs as a component of some hereditary syndromes (fetal alcohol syndrome, Down syndrome, etc.).

Prenatal diagnosis of congenital heart disease

Fortunately, it is possible to predict the birth of a child with congenital heart disease. To do this, every woman should undergo an ultrasound examination of the fetus starting from the 11th week of pregnancy.

When congenital heart disease is detected in the fetus, parents receive information about the expected viability of the child, the severity of his pathology, and the upcoming treatment.

What makes a doctor suspect congenital heart disease in a newborn?

There are a number of signs that immediately or a few days after birth suggest that the child has a congenital heart disease.

• Heart murmurs
• Cyanosis, or cyanosis of the skin.
• Heart failure, manifested by increased heart rate, respiratory rate, liver enlargement, swelling.
• Spasm of peripheral vessels: blanching and coldness of the extremities, the tip of the nose.

What can lead parents to suspect that a child has congenital heart disease?

Severe heart defects are usually recognized already in the maternity hospital. However, if the pathology is implicit, the child can be discharged home. What can parents notice? If the child is lethargic, sucks poorly, often burps, turns blue when crying or at the time of feeding, his heart rate is above 150 beats per minute, then you should definitely pay attention to this pediatrician.

How is the diagnosis of congenital heart disease confirmed?

If the doctor suspects that a child has a heart defect, the main method of instrumental diagnostics is an ultrasound examination of the heart, or echocardiography. In addition to ultrasound, a child with suspected congenital heart disease will have an electrocardiogram.

Congenital heart disease - not a sentence!

Congenital heart defects are treated mainly surgically. As a rule, after the operation, such children are no different from their peers. The earlier the operation was performed, the more chances the child has for a full life and development.

High-class doctors OKD "CD and SSH" will help in solving all problems related to your child's heart.

At the Medical Genetic Consultation :

• geneticists will advise future parents who want to have healthy offspring, assess the risk of having a child with congenital heart disease,
• specialists in ultrasound diagnostics will conduct an ultrasound examination of the fetus in pregnant women.

In the clinic OKD :

• pediatric cardiologists, pediatric cardiac surgeons examine the child, prescribe treatment, put him on a dispensary record, if necessary, send him for an operation in a timely manner,
• functional diagnostics specialists will perform echocardiography, electrocardiography and other examinations.

In the cardiac surgery department OKD :

• pediatric cardiac surgeons will perform surgical treatment, in some cases endovascular intervention is possible (without a chest incision).

Definition

\n

\nCongenital malformations are also referred to as congenital malformations, congenital disorders, or congenital deformities. Congenital malformations can be defined as structural or functional abnormalities (eg, metabolic disorders) that appear in utero and may be identified before birth, during birth, or later in life.

\n

Causes and risk factors

\n

\nApproximately 50% of all malformations cannot be attributed to any specific cause, but some causes or risk factors are known.

\n

Socio-economic factors

\n

\nAlthough low income may be an indirect determinant, malformations are more likely to occur in families and countries with insufficient resources. It is estimated that approximately 94% of severe malformations occur in middle- and low-income countries, where women often do not have access to sufficient and good enough food and may be exposed to some agent or factor, such as infection or alcohol, that provokes or enhances deviations from the norm in prenatal development. Moreover, motherhood in adulthood increases the risk of chromosomal abnormalities, including Down's syndrome, while motherhood at a young age increases the risk of certain congenital malformations.

\n

Genetic factors

\n

\nIncest (consanguinity) increases the incidence of rare genetic birth defects and almost doubles the risk of neonatal and infant mortality, mental retardation and severe birth defects in children born to first cousins . Some ethnic groups, such as Ashkenazi Jews and Finns, have a relatively high prevalence of rare genetic mutations that lead to an increased risk of malformations.\n

\n

Infections

\n

\nMaternal infections such as syphilis or measles are a common cause of birth defects in low- and middle-income countries.

\n

Maternal nutrition

\n

\nDeficiencies in iodine, folic acid, obesity, or conditions such as diabetes mellitus are associated with some malformations. For example, folic acid deficiency increases the risk of having a baby with a neural tube defect. In addition, increased intake of vitamin A may affect the normal development of the embryo or fetus.

\n

Environmental factors

\n

\nMaternal exposure to certain pesticides and other chemicals, as well as certain drugs, alcohol, tobacco, psychoactive substances, or radiation during pregnancy may increase the risk of developing the fetus or a newborn baby with birth defects. Working or living near or close to landfills, smelters, or mines can also be a risk factor, especially if the mother is exposed to other environmental risk factors or malnutrition.

\n

Prevention

\n

\nPregnancy and conception preventive health care, and prenatal care, reduce the incidence of some birth defects. Primary prevention of malformations includes the following measures:

\n

\n
• Improving the nutrition of women during the reproductive period by ensuring adequate intake of vitamins and minerals, especially folic acid, as a result of daily oral supplementation or fortification of staple foods, such as wheat or corn flour.
\n
• Supervise that a pregnant woman does not consume or consume in a limited amount unhealthy foods, especially alcohol.
\n
• Prevention of diabetes in pregnancy and during pregnancy through counseling, weight management, proper nutrition, and, if necessary, insulin administration.
\n
• Prevention of exposure to environmental hazardous substances (eg, heavy metals, pesticides, certain drugs) during pregnancy.
\n
• Ensuring that any exposure of a pregnant woman to medicines or medical exposures (such as x-rays) is justified and based on a careful analysis of the health risks and benefits.
\n
• Increase vaccination coverage for women and children, especially against rubella virus. This disease can be prevented by vaccinating children. Rubella vaccine may also be given at least one month before pregnancy to women who did not receive the vaccine or who did not have rubella in childhood.
\n
• Increase vaccination coverage for women and children, especially against rubella virus. This disease can be prevented by vaccinating children. Rubella vaccine may also be given to women who are not immune to the disease at least one month before pregnancy.
\n
• Scaling up and intensifying training for health professionals and other staff involved in strengthening malformation prevention.
\n

\n

Identification

\n

\nPre-conception (pre-conception) and near conception (per-conception) health care includes basic reproductive health care as well as medical genetic screening and counseling. Screening can be carried out during the three periods listed below.

\n

\n
• Pre-pregnancy screening is designed to identify people who are at risk of developing certain health conditions or at risk of passing on any health conditions to their children. Screening includes family medical history and vector screening. Screening is especially important in countries where incestuous marriages are common.
\n
• Preconception screening: Maternal characteristics may increase risk, and screening results should be used to provide appropriate care based on risk. During this period, screening of young and mature mothers, as well as screening for the use of alcohol, tobacco and other psychoactive substances, can be carried out. Ultrasound can be used to detect Down's syndrome during the first trimester of pregnancy and severe fetal malformations during the second trimester. Additional tests and amniocentesis help detect neural tube defects and chromosomal abnormalities during the first and second trimesters of pregnancy.
\n
• Newborn screening includes a clinical examination, as well as screening for hematological, metabolic, and hormonal disorders. Screening for deafness and heart disease, and early detection of birth defects, can facilitate life-saving treatment and prevent progression of the defect, which could lead to some form of physical, mental, or visual or hearing disability. In some countries, all newborns are screened for thyroid and adrenal abnormalities before being discharged from the maternity ward.
\n

\n

Treatment and care

\n

\nIn countries with adequate health services, structural congenital malformations can be corrected with pediatric surgery and children with functional problems such as thalassemia (inherited by recessive blood disease), sickle cell disorders, and congenital hypothyroidism.

\n

WHO activities

\n

\nIn 2010, the World Health Assembly published a report on birth defects. The report outlines the main components of establishing national programs for the prevention and care of birth defects before and after birth. The report also recommends priority actions for the international community to help establish and strengthen such national programs.

\n

\nThe Global Strategy for Women's and Children's Health, announced in September 2010 by the United Nations, in collaboration with government leaders and other organizations such as WHO and UNICEF, plays a critical role in implementing efficient and cost-effective action to promote newborn and child health.\n

\n

\nWHO is also working with the National Center for Birth and Developmental Disorders, part of the US Centers for Disease Control and Prevention (CDC), and other partners to develop a global policy to fortify foods with salt folic acid at the country level. In addition, WHO is working with partners to provide the necessary technical expertise to conduct surveillance of neural tube defects, monitor efforts to fortify foods with folic acid salts, and strengthen laboratory capacity to assess risks for birth defects prevented by folic acid salts.

\n

\nThe International Clearing House for Surveillance and Research on Birth Defects is a voluntary, non-profit, international organization in official relations with WHO. This organization collects surveillance data on birth defects and research programs around the world to study and prevent birth defects and mitigate their effects.

\n

\nThe WHO Departments of Reproductive Health and Research and Nutrition for Health and Development, in collaboration with the International Clearing House for Surveillance and Research on Birth Defects and the CDC National Center for Birth Defects and Development, organize annual seminars on surveillance and prevention of birth defects and preterm birth. The WHO Department of HIV/AIDS is collaborating with these partners to strengthen surveillance for malformations among women receiving antiretroviral drugs during pregnancy as an integral part of the monitoring and evaluation of national HIV programs.

\n

\nThe GAVI Alliance, partnered with WHO, is helping developing countries to increase the control and elimination of rubella and congenital rubella syndrome through immunization.

\n

\nWHO is developing normative tools, including guidelines and a global plan of action to strengthen health care and rehabilitation services in support of the implementation of the Convention on the Rights of Persons with Disabilities. Similarly, WHO is helping countries integrate health care and rehabilitation services into general primary health care, supporting the development of community-based rehabilitation programs and strengthening specialized rehabilitation centers and their links with community-based rehabilitation centers.

\n

United Nations Convention on the Rights of Persons with Disabilities

\n

\nThe WHO Department of Public Health and Environment works across a range of areas and develops interventions to address the environmental and social determinants of child development. These include: child-only vulnerability to indoor and outdoor air pollution, water pollution, lack of basic hygiene, toxic compounds, heavy metals, waste components and radiation exposure; mixed impact of factors related to the social environment, professional activities and nutrition, as well as the living conditions of children (home, school).

Key Facts

• An estimated 303,000 children die each year from malformations in the first 4 weeks of life.
• Developmental disabilities can lead to long-term disability, which has a significant impact on individuals, their families, health systems and society.
• The most severe malformations include heart defects, neural tube defects and Down's syndrome.
• Although malformations may be genetic, infectious or environmental in origin, the exact cause is often difficult to establish.
• Some birth defects can be prevented. The main elements of prevention are, inter alia, vaccination, adequate intake of folic acid or iodine through fortification of staple foods or provision of nutritional supplements, and proper prenatal care.

Malformations and preterm birth are major causes of childhood death, chronic disease and disability in many countries. In 2010, the World Health Assembly adopted a resolution calling on all Member States to promote primary prevention and health promotion for children with developmental disabilities through:

• development and strengthening of registration and surveillance systems;
• experience and capacity building;
• strengthening research and scientific work in the field of etiology, diagnosis and prevention;
• strengthening international cooperation.
