7 Situations That Require A Cardiac Ultrasound

Cardiac ultrasound, or echocardiography, is a non-invasive diagnostic imaging technique that uses sound waves to create detailed images of the heart. This powerful tool allows healthcare professionals to visualize the structure and function of the heart, providing valuable information for the diagnosis and management of various cardiac conditions.

Although cardiac ultrasound is used in a wide range of situations, there are seven specific scenarios where it is particularly vital. That said, this article will explore these situations and highlight the importance of cardiac ultrasound in each case.


How Does Cardiac Ultrasound Work?

During the cardiac echo, the healthcare provider uses a hand-held wand called a transducer placed on the chest to capture images of the heart’s valves and chambers.

To enhance the assessment of blood flow across the heart valves, healthcare providers often combine cardiac ultrasound with Doppler color techniques and Doppler ultrasound. These additional techniques allow them to study the movement and direction of blood within the heart, providing valuable insights into circulation efficiency.

One of the advantages of cardiac ultrasound is that it does not involve radiation. Unlike conventional imaging tests like CT scans and X-rays emitting radiation, cardiac ultrasound offers a safer alternative with minimal risk.

In addition, the procedure itself is typically performed by a specially trained technician known as a cardiac sonographer. These professionals undergo specialized training from reliable institutions in their location, such as Zedu Ultrasound Training which offers essential advanced ultrasound training, equipping an individual with the necessary skills to excel in this field.

Common Situations To Undergo Cardiac Ultrasound

Here are several situations in which undergoing a cardiac ultrasound becomes necessary:

When Checking Blood Flow

When Checking Blood Flow

Healthcare providers utilize cardiac ultrasound to assess the blood flow of patients. This involves emitting sound waves of different frequencies and analyzing their entry and exit patterns through the transducer.

Colored ultrasounds are employed by doctors to precisely determine the speed and direction of blood flow within the heart. In this technique, blood flowing away from the transducer appears blue, while blood flowing towards it appears red.

By examining the cardiac ultrasound results, healthcare providers can identify potential concerns regarding heart defects and evaluate the passage of blood through these defects.

When Conducting A Stress Test

A stress test, also known as a stress exercise test, is a diagnostic procedure doctors use to assess how the heart responds during intense physical activity. It typically involves activities such as treadmill walking or stationary biking.

The primary objectives of a stress test are as follows:

  • Evaluating the heart’s ability to pump blood effectively.
  • Assessing whether the heart receives an adequate blood supply.
  • Observing the patient’s performance and any symptoms experienced during physical exertion.

Furthermore, stress tests help doctors determine the need for additional or more invasive diagnostic procedures. By examining the cardiac ultrasound results, healthcare providers can identify potential concerns regarding heart defects and evaluate the passage of blood through these defects. It also aids in confirming whether the provided treatment can improve the patient’s well-being.

In some cases, doctors may order a cardiac echo (specifically, a transthoracic echo) before and after the stress test. This additional step enables the diagnosis of potential heart conditions such as arrhythmia, heart valve problems, coronary heart disease, and ischemic heart disease.

When Checking An Infant’s Heart

In the process of monitoring an unborn baby’s heart, doctors may prescribe a cardiac ultrasound known as a fetal echocardiogram. This specialized procedure is typically conducted between the 18th and 22nd week of pregnancy.

A fetal echocardiogram is a safe diagnostic tool as it does not involve radiation, ensuring the well-being of both the mother and the developing baby.

By performing a fetal echocardiogram, healthcare providers can carefully observe and evaluate the structure and function of the infant’s heart. This valuable information assists in identifying any potential abnormalities or congenital heart conditions at an early stage, allowing for timely medical intervention and appropriate management.

When Looking For A More Detailed Image Of The Heart

In cases where more precise and comprehensive heart images are required, doctors may opt for a transesophageal echocardiogram (TEE).

During a TEE, the patient may receive local anesthesia to alleviate the gag reflex and a sedative to relax the muscles in the throat. Once the anesthesia and sedative have taken effect, a small transducer is inserted through a tube into the throat and esophagus, allowing it to reach the posterior region of the heart.

Subsequently, the doctor maneuvers the transducer while a sonographer captures images of the heart. Despite the probe being moved in the esophagus, the patient typically doesn’t feel its motion after swallowing it.

This procedure is beneficial in diagnosing specific cardiac conditions and guiding treatment decisions, as it provides healthcare professionals with a highly detailed perspective of the heart’s anatomy and function.

When Someone Has A Heart Problem

In cases where an individual exhibits symptoms indicative of a potential heart problem, doctors may prescribe a cardiac ultrasound to aid in the diagnosis. The following symptoms may prompt the ordering of a cardiac ultrasound:

  • Irregular heartbeat (arrhythmia)
  • Shortness of breath
  • Low or high blood pressure
  • Swelling in the legs
  • Abnormal electrocardiogram (ECG) results
  • Heart murmurs (unusual sounds between heartbeats)

These symptoms can be suggestive of an underlying heart condition. Consequently, it becomes crucial to conduct a cardiac ultrasound to confirm the presence of a heart problem. By performing the ultrasound, healthcare providers can obtain detailed images of the heart’s structures and functions, enabling them to accurately identify and assess any potential abnormalities or cardiac disorders.

When Diagnosing A Heart Condition

The most common application of cardiac ultrasound is to diagnose a heart condition. The transthoracic echocardiogram, a widely employed test, is typically used for this purpose.

A gel is applied to the patient’s chest during a transthoracic echocardiogram. This gel facilitates the transmission of sound waves from the transducer. These sound waves are then directed toward the patient’s heart, where they bounce back, generating images of the heart’s structure on a screen.

A skilled sonographer will position the transducer above the chest and maneuver it to capture views of the heart from multiple angles. They may instruct the patient to change positions, take deep breaths, or apply slight pressure during transducer movement to enhance the clarity of the obtained images.

This diagnostic procedure plays a crucial role in providing valuable information for accurate diagnosis, guiding treatment decisions, and monitoring the progress of heart conditions.

When Looking For Heart Problems

Doctors may order a cardiac ultrasound to look for the following conditions:

  • Abnormal Aortic Aneurysm: This condition involves the gradual enlargement of the aorta, the body’s largest blood vessel. As it often develops without noticeable symptoms, it can be challenging to detect. However, persistent abdominal or back pain and a pulsating sensation near the belly button may indicate an abnormal aortic aneurysm.
  • Congenital Heart Disease: This heart condition manifests at birth and can affect the structure and function of the baby’s heart. In such cases, a fetal echocardiogram may be required to observe and visualize the baby’s heart, aiding in the early diagnosis and management of congenital heart disease.
  • Endocarditis: Characterized by inflammation in the heart’s valves and chambers, endocarditis is typically caused by bacterial or fungal infections. If left untreated, it can damage the heart valves, potentially resulting in severe complications and even death. Symptoms may include chest pain, fatigue, shortness of breath, and heart murmurs.
  • Hypertrophic Cardiomyopathy: This condition involves the thickening and stiffening of the heart’s main pumping chamber, the left ventricle. As a result, the heart struggles to pump blood effectively during each heartbeat, potentially leading to serious health complications such as stroke, heart failure, and atrial fibrillation.

Cardiac ultrasound is also instrumental in identifying other heart problems, such as pericarditis, valvular heart disease, pericardial effusion, and aortic dissection.

Final Words

Cardiac ultrasound plays a vital role in diagnosing and monitoring various heart conditions. Whether it is assessing blood flow, evaluating heart function during physical activity, examining an unborn baby’s heart, or detecting abnormalities and diseases, a cardiac ultrasound provides valuable insights that aid in accurate diagnosis and effective treatment planning.

Lastly, it improves patient care, early intervention, and better outcomes for individuals facing potential heart problems by enabling healthcare providers to visualize the heart’s structures and functions.
