Sonographer doing pediatric echocardiography. Echocardiogram in the parasternal long- axis view, showing a measurement of the heart's left ventricle. An echocardiogram, often referred to as a cardiac echo or simply an echo, is a sonogram of the heart. It is one of the most widely used diagnostic tests in cardiology. It can provide a wealth of helpful information, including the size and shape of the heart (internal chamber size quantification), pumping capacity, and the location and extent of any tissue damage. An echocardiogram can also give physicians other estimates of heart function, such as a calculation of the cardiac output, ejection fraction, and diastolic function (how well the heart relaxes). Echocardiography can help detect cardiomyopathies, such as hypertrophic cardiomyopathy, dilated cardiomyopathy, and many others. The use of stress echocardiography may also help determine whether any chest pain or associated symptoms are related to heart disease. The biggest advantage to echocardiography is that it is not invasive (does not involve breaking the skin or entering body cavities) and has no known risks or side effects. Not only can an echocardiogram create ultrasound images of heart structures, but it can also produce accurate assessment of the blood flowing through the heart by Doppler echocardiography, using pulsed- or continuous- wave Doppler ultrasound. This allows assessment of both normal and abnormal blood flow through the heart. Color Doppler, as well as spectral Doppler, is used to visualize any abnormal communications between the left and right sides of the heart, any leaking of blood through the valves (valvular regurgitation), and estimate how well the valves open (or do not open in the case of valvular stenosis). The Doppler technique can also be used for tissue motion and velocity measurement, by tissue Doppler echocardiography. Echocardiography was also the first ultrasound subspecialty to use intravenous contrast. Edler in 1. 95. 3 produced the first echocardiographs using an industrial Firestone- Sperry Ultrasonic Reflectoscope. In developing echocardiography, Edler worked with the physicist Carl Hellmuth Hertz, the son of the Nobel laureate. Gustav Hertz and grandnephew of Heinrich Rudolph Hertz. In this case, the echocardiography transducer (or probe) is placed on the chest wall (or thorax) of the subject, and images are taken through the chest wall. This is a noninvasive, highly accurate, and quick assessment of the overall health of the heart.

A specialized probe containing an ultrasound transducer at its tip is passed into the patient's esophagus. This allows image and Doppler evaluation from a location directly behind the heart. This is known as a trans. Transesophageal echocardiograms are most often used when transthoracic images are suboptimal and when a more clear and precise image is needed for assessment. This test is performed in the presence of a cardiologist, registered nurse, and ultrasound technician. Conscious sedation and/or localized numbing medication may be used to make the patient more comfortable during the procedure. Stress echocardiography. First, images of the heart are taken . The patient then walks on a treadmill or uses another exercise modality to increase the heart rate to his or her target heart rate, or 8. Finally, images of the heart are taken . A stress echo assesses wall motion of the heart; it does not, however, create an image of the coronary arteries directly. Ischemia of one or more coronary arteries could cause a wall motion abnormality which could indicate coronary artery disease. Echocardiography in Pediatric and Congenital Heart Disease addresses the needs of. The gold standard test to directly create an image of the coronary arteries and directly assess for stenosis or occlusion is a cardiac catheterization. A stress echo is not invasive and is performed in the presence of a licensed medical professional, such as a cardiologist, and a cardiac sonographer. Three- dimensional echocardiography. This enables detailed anatomical assessment of cardiac pathology, particularly valvular defects. All generic models refer to a dataset of anatomical information that uniquely adapts to variability in patient anatomy to perform specific tasks. Built on feature recognition and segmentation algorithms, this technology can provide patient- specific three- dimensional modeling of the heart and other aspects of the anatomy, including the brain, lungs, liver, kidneys, rib cage, and vertebral column. The ultrasound contrast is made up of tiny microbubbles filled with a gas core and protein shell. This allows the microbubbles to circulate through the cardiovascular system and return the ultrasound waves creating a highly reflective image. The most commonly used types of ultrasound contrast are known as: Definity. Both have been approved by the FDA. There are multiple applications in which contrast- enhanced ultrasound can be useful. The most commonly used application is in the enhancement of LV endocardial borders for assessment of global and regional systolic function. Contrast may also be used to enhance visualization of wall thickening during stress echocardiography, for the assessment of LV thrombus, or for the assessment of other masses in the heart. Contrast echocardiography has also been used to assess blood perfusion throughout myocardium in the case of coronary artery disease. The Contrast Echo Box developed by the European Association of Echocardiography, and the American Society of Echocardiography Contrast Zone both offer a complete review of Contrast Echocardiography. Accreditation. All sonographers involved in echo need to be highly trained and registered. At European level . Three subspecialties for individual accreditation: Adult Transthoracic Echocardiography (TTE), Adult Transesophageal Echocardiography (TEE) and Congenital Heart Disease Echocardiography (CHD). In the UK, accreditation is regulated by the British Society of Echocardiography. Accredited radiographers, sonographers, or other professionals must complete a logbook and pass an exam. Cardiologists and sonographers who wish to have their laboratory accredited by IAC must comply with these standards. The purpose of accreditation is to maintain quality and consistency across echocardiography labs in the United States. Accreditation is offered in adult and pediatric transthoracic and transesophageal echocardiography, as well as adult stress and fetal echo. Accreditation is a two part process; first each facility will conduct a detailed self- evaluation, paying close attention to the IAC standards and Guidelines. The facility will then complete the application and submit actual case studies to the board of directors for review. Once all requirements have been met, the lab will receive IAC certification. IAC certification is a continual process and must be maintained by the facility, this may include audits or site visits by the IAC. There are several states in which Medicare and/or private insurance carriers are requiring either the accreditation of the laboratory and/or sonographer credentialing, for reimbursement of echocardiograms. Both CCI and ARDMS have earned the prestigious ANSI- ISO 1. International Organization for Standardization (ISO). Accreditation is granted through the American National Standards Institute (ANSI). Recognition of ARDMS programs in providing credentials has also earned the ARDMS accreditation with the National Commission for Certifying Agencies (NCCA). The NCCA is the accrediting arm of the National Organization for Competency Assurance (NOCA). Established in 1. NOCA is a leader in setting. Under both credentialing bodies sonographers must first document completion of prerequisite requirements which contain both didactic and hands on experience in the field of ultrasound. Applicants must then take a comprehensive exam demonstrating knowledge in both the physics of ultrasound and the clinical competency related to their specialty. Credentialed sonographers are then required to maintain competency in their field by obtaining a certain number of Continuing Medical Education credits, or CME. This is reviewed and accepted providing the sonographer gains points every 3 years for ongoing education. Physician credentialing. The purpose of the NBE is to assess the level of knowledge of a practitioner in echocardiography, maintain a high level of standard in the field, and serve the public by maintaining a high level of patient care. Similar to sonographer credentialing, physicians are required to document specialized training in cardiovascular disease, and specifically echocardiography, as well as taking a comprehensive exam demonstrating knowledge in the field. Certification is available in Transthoracic, Transesophageal, and Stress echocardiography. Physicians are also required to maintain their credentials by taking a recertification exam. American Society of Echocardiography. Echocardiography was invented by Milton R. Hejtmancik, MD, from which he was awarded the AMA Billings Gold Medal in 1. The Society was founded in 1. The American Society of Echocardiography is an organization from which sonographers and physicians may obtain Continuing Medical Education Credits, as well as interact with other health professionals from across the country and the world. The ASE is committed to maintaining and improving the profession of cardiac ultrasound through education, advocacy, research, and innovation. The first president of the ASE was Harvey Feigenbaum, MD in 1. The ASE produces a monthly circulation known as the Journal of the American Society of Echocardiography (JASE) which highlights important educational and research advances in the field of echocardiography. The ASE not only focuses on improving the profession of echocardiography in the US, but also focuses on bringing echocardiography to the world through ASE Global.
