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