Echocardiography uses ultrasound waves to generate images of cardiovascular structures and to display information regarding the blood flow through these structures. Knowledge of basic ultrasound principles and current technology is essential for image interpretation and for optimal use of equipment during image acquisition and post-processing. This chapter starts by presenting the physics of ultrasound and the construction and function of instruments. Image formation, optimization, display, presentation, storage, and communication are explained. Advantages and disadvantages of available imaging modes (M-mode, two-dimensional, and three-dimensional) are detailed and imaging artefacts are illustrated. The potential biologic effects of ultrasound and the need for quality assurance are discussed.

Congenital abnormalities of the left atrioventricular (AV) valve are a significant diagnostic challenge. Traditionally, reliance has been placed on two-dimensional echocardiographic (2DE) imaging to guide recognition of the specific morphological features. Real-time 3DE can provide unique views of the left AV valve with the potential to improve understanding of valve morphology and function to facilitate surgical planning. This review illustrates the features of congenital abnormalities of the left AV valve assessed by 3DE. The similarities and differences in morphology between different lesions are described, both with respect to the valve itself and supporting chordal apparatus. The potential advantages as well as limitations of this technique in clinical practice are outlined.

Abstract Background Non-compaction of the ventricular myocardium (LVNC) is a rare genetically determined heart defect. The disease is most frequently detected during accidental echocardiography. There is no golden rule examination for LVNC diagnosis. In our study, we aimed to compare the measurements of the left ventricle volumes and function obtained with the two-dimensional, and three-dimensional echo based on the results from MR imaging in a series of three left ventricle non-compaction cardiomyopathy patients. Case presentation Patients’ age was 43–53 years. Two patients presented with congestive heart failure, third patient presented with ventricular arrhythmia. The proportion of thickness of non-compacted to compacted layers ranged from 2.3 to 3.6. Three-dimensional echo has revealed substantially higher end-diastolic and end-systolic volumes in comparison to two-dimensional echo, yet not as high as assessed in magnetic resonance imaging. Speckle tracking revealed reduced global longitudinal, radial, and circumferential strain, even in the patients with normal left ventricle function. Conclusion Real-time three-dimensional echocardiography with automated left ventricle analysis offers more information on the assessment of left ventricle in patients with left ventricle non-compaction in comparison to two-dimensional echocardiography. Speckle tracking analysis may add prognostic information in this specific group of patients.

And Function

Transthoracic echocardiography is by far the most frequently used imaging procedure in cardiology. Adherence to a standard protocol is essential for a comprehensive evaluation of cardiac structures and function. The protocol must include the minimal requirements outlined in this chapter. Two-dimensional imaging is performed from specific windows, such as the parasternal, apical, and subcostal ones. A number of standard cut planes are needed for a full understanding of the entire heart. M-mode, spectral, and colour Doppler are used to obtain additional anatomical and functional information. Advanced techniques such as deformation imaging, three-dimensional, or contrast echocardiography may be used if needed. A set of standard measurements, as outlined in this chapter, are equally important.
