The purpose of this chapter is to review the core educational and training requirements for cardiologists, noncardiologist physicians, and cardiac sonographers to be adequately qualified to perform echocardiography. Echocardiography training, teaching milestones, and expectations from a cardiac sonographer or a fellow (cardiology or echocardiography) needs to be well defined. In this chapter, the various modes including 2D, 3D, M-mode, continuous wave, pulsed wave, color Doppler as well as different approaches (transthoracic, transesophageal, intraoperative, intravascular, and epicardial) add to the diagnostic utility of echocardiography methods are described in detail. The echocardiogram is a relatively inexpensive and noninvasive test compared to computed tomography (CT) and magnetic resonance imaging (MRI), making it a preferred initial imaging modality. Moreover, newer improvements of the technology including tissue Doppler and speckle tracking echocardiography are on the clinical anvil. In spite of all the developments, echocardiography as a diagnostic tool is largely operator-dependent and to ensure objective accuracy of interpretations, the training in image acquisition and interpretation needs to be rigorous and standardized. 2 tables are included to highlight the summary of training requirements for echocardiography (as per ACC), cognitive skills required for competence in adult transthoracic echocardiography. 2 comprehensive and self-explanatory images are included in this chapter. And 18 references are given at the end of the chapter to facilitate further reading.
