Influence of guiding catheter selection on the measurement of coronary flow reserve

Am J Cardiol. 1997 Mar 1;79(5):703-4. doi: 10.1016/s0002-9149(96)00850-8.

Abstract

The impact of guiding catheter selection on the measurement of coronary flow reserve was assessed by injecting increasing doses of adenosine through 3 different catheters often used during coronary interventions. When guiding catheters with side holes were used, an approximate doubling of the adenosine dose was required to produce a coronary flow reserve response similar to a 12-micrograms dose of adenosine injected through guiding catheters without side holes.
