RESUMO
Echocardiography is the primary method for noninvasive evaluation of cardiovascular system in children. However, conventional echocardiography cannot observe and analyze transient cardiac events and transient phases due to its low temporal resolution, nor can it evaluate the mechanical properties of myocardium. In recent years, ultrasonic imaging technology, and the improvement of computing capacity greatly promoted the development of the ultrafast cardiac shear wave imaging, allowing the speed of 5 000 frames/s via chest cardiac imaging, has fast dynamic movement of heart tissue, real-time observation for myocardial properties, function and blood flow to the heart pattern advantages, can better diagnose cardiovascular disease in children. In this paper, the principle of ultrafast cardiac shear wave imaging and its recent application in pediatric cardiac imaging are reviewed.
