Role of Echocardiography in Blood Flow Obstruction Disorder

Ultrasound of the heart (echocardiography) is one of the most widely used techniques for diagnosing cardiac disease since it provides excellent quality images and is:

  1. Non-invasive
  2. Harmless
  3. Relatively cheap
  4. Widely available

echocardiography

Level 2 ultrasound is also used to diagnose vascular disorders in other parts of the body.

Echocardiography can be used to detect if the heart muscle is moving normally and to measure the volume of blood pumped with each beat. This procedure can also detect abnormalities in the structure of the heart, such as defects in the heart valves , congenital anomalies (such as holes in the walls between the different chambers of the heart) and increased thickness of the walls or chambers of the heart. One should get complete information about doppler ultrasound cost before undergoing any diagnosis.

Echocardiography can also be used to detect a pericardial effusion, in which there is fluid accumulation between the two layers of the heart (pericardium) and constrictive pericarditis, in which scar tissue forms throughout the pericardium. It also detects dissection of the aorta, a tear inside the layers of the aortic wall.

The main types of ultrasound are:

  1. Two-dimensional
  2. Three-dimensional
  3. Doppler
  4. Color doppler

The two - dimensional ultrasound is the technique most widely used and produces realistic two - dimensional images, for "cuts" generated by computer. By joining the cuts, you can recreate a three-dimensional structure.

The Doppler ultrasound shows the direction and speed of blood circulation, so that it can detect the turbulent flow caused by a narrowing or blockage of blood vessels.The Doppler color shows the different speeds of blood flow in different colors.

4D ultrasound test and color doppler ultrasound are frequently used to help diagnose disorders that affect the heart and arteries and veins of the trunk, legs, and arms. Since these procedures can show the direction and speed of blood flow in the heart's chambers and blood vessels, they allow the doctor to assess the structure and function of these parts. For example, it is possible to determine whether the heart valves open and close correctly, whether and how much blood leaks when closed, and whether blood flows normally. Abnormal connections between an artery and a vein or between the heart chambers can also be detected.

How echocardiography is performed?

Ultrasound waves are emitted by a probe that can both emit and detect them (transducer). Typically, the transducer is portable and is placed on the chest over the heart. The examiner gels the skin under the transducer to help transmit the sound waves. The transducer is connected to a computer that displays the image on a screen and stores it in digital format. By changing the position and angle of the transducer, doctors can look at the heart and major nearby blood vessels from various angles to get a detailed picture of cardiac structures and function. During several moments of the exam, the person must hold their breath for about 10 seconds to ensure that well-defined images are obtained.

Color Doppler Echocardiography

Transesophageal echocardiography may be performedif the doctor needs to get more definition or to analyze the aorta or the structures of the back of the heart (especially the left atrium or the left ventricle). To carry out this procedure in ultrasound lab, a small flexible tube with an ultrasound transducer is passed through the end of the affected person's throat into the esophagus, so that the transducer is located just behind the heart. Since this procedure is uncomfortable, the person is sedated and the throat is anesthetized with an anesthetic spray. Transesophageal ultrasound test is also used when there is difficulty in performing common echocardiography due to obesity, lung disorders or other technical problems, or when the diagnosis of endocarditis is made.

Scanner, MRI, Radio: Which Exam For Which Indication?

Depending on the medical indication, the specificities of the area to be studied, or the profile of the patient, the doctor has a wide choice of medical imaging techniques.

X-ray

Standard radiography uses X-rays that pass through the human body, being more or less absorbed by the tissues according to their density. It allows to obtain two-dimensional images of "full" structures. This technique is, therefore, well suited to the observation of bones and joints. Orthopedics, rheumatology, or orthodontics, use radiography to study trauma (fractures, etc.), skeletal deformities, or the implantation of teeth.

It is also possible to visualize certain organs or hollow parts, usually invisible to X-rays, by "filling" them with an opaque contrast product: this is the contrast radiography.

CT or computed tomography

The scanner, which also uses X-rays, explores the body in volume and thus makes it possible to establish 3D images of organs or tissues scanned: bone, muscles, vessels, or brain. The images obtained are "sectional" images.

The scanner makes it possible to visualize a change of volume or a structural anomaly (tumor, embolism, aneurysm, etc.). It will reveal a narrowing of the coronary arteries in case of chest pain or myocardial infarction. It can also be used in surgery to inform doctors about areas where the intervention is planned, as well as oncology, to control the response to chemotherapy or guide biopsies.

Magnetic resonance imaging (MRI)

The MRI allows to visualize the anatomical structure of the body volume. Anatomic MRI is distinguished from functional MRI.

Anatomical MRI is based on the magnetization of hydrogen atoms present wherever there is water and fat. It is, therefore, particularly adapted to the observation of "soft tissues," such as the brain, the spinal cord, the muscles, the tendons, or the viscera (liver, spleen, and kidney).

Functional MRI is based on the measurement of the deoxy-hemoglobin of red blood cells (the hemoglobin devoid of oxygen leaving the organs). It thus makes it possible to follow the influx of oxygenated blood in the organs, and thus it is very used in the cerebrovascular accidents, but also, in neurology, to make the diagnosis of Alzheimer's disease or multiple sclerosisby visiting MRI test labs in Delhi.

Ultrasound

An ultrasound probe emits ultrasound, sound waves imperceptible to the ear, in the direction of a solid object. They bounce off the object and then return to the starting point. The system allows to explore the heart, the viscera (liver, spleen, pancreas, bladder, bladder, kidneys), and the genital tract (ovaries, uterus, prostate). On the other hand, the digestive tract, the lungs, and the bones are not acceptable.

Doppler ultrasound allows the vascular system to be explored with a thinner probe that can be introduced into the vessel lumen. It is indicated for exploratory examinations in diseases of the veins and arteries. It is important to first know Doppler ultrasound cost.

Finally, ultrasounds of pregnancy, which do not present a danger for the foetus, allow its morphology and its environment: amniotic fluid, placenta, cord.

Applications And Need Of Doppler Ultrasound Test

Doppler ultrasound, or simply Eco Doppler, is one of the types of ultrasound that, based on the use of ultrasound, uses the Doppler effect.

In the case of ultrasound, the sound waves leave the ultrasound through the transducer, and bounce off the moving blood, generating different waves depending on the direction and speed of the blood flow. When the blood approaches the ultrasound the frequency will be higher and when it moves away less, this alteration in the ultrasound waves is interpreted by the ultrasound and it assigns a specific colour for each frequency, red, blue and yellow.

Through this method and thanks to this physical principle of sound waves, it is possible to evaluate the flow of vascular structures of any part of the body, being able to determine its existence, its speed and direction of flow.

Why is it important to perform a doppler ultrasound?

The Doppler ultrasound allows to know the amount of blood flow circulating through cavities and veins baby. Its importance is that its results can tell you how much blood is pumped with each beat, thus determining the good state of the baby's heart, in addition to corroborating that the blood is reaching the foetus correctly, and with it the oxygen and the nutrients

But not only important is that sense. Its realization can help detect cardiac malformations in the foetus, problems with the umbilical cord and placenta, so that you and your gynaecologist begin to act quickly, or you can simply rule out these types of problems and make sure that your baby will be born healthy.

When do you have to have a Doppler ultrasound?

This test is usually done to all pregnant women in the third trimester, starting at the 25th week of pregnancy. However, Doppler ultrasound is a non-mandatory quarterly test, which can also be done in the first and second trimesters if the gynecologist considers it necessary.

The cases in which the doctor can recommend you to do this ultrasound are the following:

In case it is suspected that there is a growth delay in the foetus. In this circumstance the doppler ultrasound is very useful to control that the baby receives blood, oxygen and nutrients correctly. In addition, it will also help to know if there are significant blood disorders to anticipate the time of delivery or to predict whether there will be a premature delivery.

If your pregnancy is listed as a risk pregnancy it is recommended that you have an ultrasound of this type in each trimester of pregnancy.

If you suffer from hypertension, what is known as preeclampsia, or you have circulatory problems in the veins. In these cases, if you decide to have this test, you will rule out that your problems are affecting the correct development of the baby.

In the case of heart disease, Doppler ultrasound also works, as you can see if this problem can affect the growth of your baby. This test is performed with the accompaniment of an echocardiogram.

If you plan to go through surgery, Doppler ultrasound is also necessary, since thanks to the study of the flow of the area to be operated you can see if there will be complications a priori.

Risk preeclampsia? Doppler ultrasound makes sense

Preventative appointments during pregnancy should provide the best possible control of your health and the healthy development of your unborn child. Science strives for the continuous development of medical procedures. A recognized examination method is ultrasound.

Now the researchers have succeeded in using Doppler ultrasound to detect a known risk factor for preterm birth. To get complete health care services, one must know doppler ultrasound cost.

One of the most common causes of prematurity_ Preeclampsia

In some women, an immune reaction already develops in early pregnancy, which leads to malformation of the blood vessels in the placenta. The circulation of the nutcake is thereby disturbed - via messenger substances; this is reported back to the cardiovascular system. To provide the unborn child with enough blood, the body responds by increasing blood pressure.

This disease is called preeclampsia. Symptoms include:

  • headache
  • dizziness
  • drowsiness
  • nausea
  • vomiting
  • blurred vision

Preeclampsia can become very dangerous during pregnancy. It gets too little blood to the child; it creates a life-threatening situation. The only countermeasure of the pregnant woman's body is a further increase in blood pressure. As soon as the mother's body can no longer supply enough blood to the baby, the contractions are prematurely initiated. Either it comes to premature birth, or the blood pressure is increased again so that the pregnant woman herself is in mortal danger. One must get an idea about ultrasound test cost in Noida to prevent the chances of premature preeclampsia. In case of risk factors Doppler ultrasound examination is advisable.

Although the causes are not yet clearly understood, factors are identified that indicate a possible development of preeclampsia. These are:

- Age (older than 35 years or younger than 18 years)

- Overweight (BMI > 30)

- Chronic diseases (high blood pressure, diabetes mellitus, kidney disease, coagulation disorders)

- Preeclampsia in a previous pregnancy or in the family

- multiple pregnancies

So far, the diagnostic options for preeclampsia were not mature, so that it was often found only when symptoms occurred. This has usually made medical treatment difficult - not infrequently had the pregnancy (prematurely) by an (emergency) childbirth be terminated. Thus, preeclampsia is the cause of up to 50 percent of premature births.

Meanwhile, a diagnosis through Doppler ultrasound is already possible in the 11th to 13th week of pregnancy. With this method, the speed of the flowing blood is measured. It is checked whether the circulation of the placenta is disturbed. One should also go for abdominal ultrasound cost in Delhi to get an idea about the risk factors of fetus development.

To counteract a worsening of blood coagulation in the mother cake, early intake of low-dose acetylsalicylic acid (ASA) is necessary. Thus, the aggravation of preeclampsia can be prevented. However, one should remember that the dose of the drug must begin before the 16th week. Otherwise, it will be ineffective. Early onset of drug treatment improves the child's blood supply and can significantly prolong pregnancy in many cases.

Hope! It helped you.
