Abstract

Transcutaneous Aortovelography (TAV), a non-invasive Doppler ultrasound technique of measuring mainstream flow velocity in the aorta, has made flow-related information on the central circulation almost as simple to obtain in most subjects as blood pressure has been since the development of the inflated cuff method. The instrumentation, with on-line spectral recorder, has rendered the acquisition of trustworthy data an undemanding and quick procedure. TAV has been shown to give reliable and relatively accurate measurements of flow changes and a useful indication of abnormalities in absolute cardiac output. The pulsatile waveform, which reflects the manner of left-ventricular ejection, conveys diagnostic information. Studying transient responses to various stimuli may help further in patient assessment. In patient management, TAV has provided valuable feedback of response to thereapy and has allowed this to be optimised. It also provides a convenient, safe and patient-acceptable tool for studying the haemodynamic effects of physiological and pharmacological influences on man.
