title: Influence of guiding catheter selection on the measurement of coronary flow reserve.
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.
