Direct demonstration by transthoracic Doppler echocardiography of adenosine-induced coronary steal in the collateral-dependent vessel.
Coronary flow velocity reserve was measured to assess the frequency of coronary steal in the collateral-dependent coronary arteries using transthoracic Doppler echocardiography. Coronary steal occurred in half the vessels studied. There was no significant difference between coronary flow velocity reserve in poorly and well-developed collaterals.
