TY - JOUR T1 - Intracoronary demonstration of adenosine-induced coronary collateral steal. JF - Heart JO - Heart SP - 78 LP - 81 DO - 10.1136/hrt.77.1.78 VL - 77 IS - 1 AU - C. Seiler AU - U. Kaufmann AU - B. Meier Y1 - 1997/01/01 UR - http://heart.bmj.com/content/77/1/78.abstract N2 - A steal phenomenon was detected by intravascular Doppler guidewire in a patient with a well collateralised coronary vascular area supplied by a reopened left circumflex coronary artery. This phenomenon accounted for the fall in blood flow velocity reserve during hyperaemic conditions to 50% of the baseline value. The collaterals must have been the cause of the steal phenomenon because complete revascularisation of the lesion barely reversed it. ER -
