Intracardiac examination using an ultrasound machine

As a result of the conducted research, data of important scientific and practical significance were obtained. The work opens up a new practical direction of using a new multi-frequency vector catheter sensor equipped with all the possibilities of Dopplerography in clinical practice. The method of intravascular and intracardiac imaging using a catheter sensor made it possible to assess in more detail the spatial location, configuration and features of the function of small and a number of hard-to-reach structures of the heart and blood vessels, increased the level of diagnosis. A technique for examining the heart and large vessels using a multi-frequency vector intravascular sensor has been developed and introduced into clinical practice.
