Progress of clinical application of speckle tracking echocardiography in Transcatheter Aortic Valve Implantation or Transcatheter Aortic Valve Replacement

Abstract

The clinical application evaluation of non-invasive imaging in transcatheter aortic valve implantation has also gradually developed. The advantages of ultrasound are gradually revealed in the evaluation of cardiac function before, during and after surgery, as well as short-term and long-term follow-up. Speckle tracking echocardiography (STE) is a non-invasive and angle-dependent new ultrasound diagnostic technique, which is used to evaluate the multi-angle and multi-directional motion velocity, strain and strain rate of human myocardium. The prognosis, recovery and risk stratification have good predictive evaluation value. With the continuous development of new related technologies and parameters from STE, scholars continue to apply these new technologies and new parameters to the clinical evaluation of transcatheter aortic valve implantation. A review of the clinical application of aortic valve implantation.
