CORONARY FLOW RESERVE Intracoronary papaverine : an ideal
An ideal coronary vasodilator for studying coronary flow reserve in humans would rapidly produce maximal coronary vasodilation, be short acting to permit repeated measurements, and not alter systemic hemodynamics. The two commonly used vasodilators (dipyridamole and meglumine diatrizoate) do not satisfy these criteria; meglumine diatrizoate does not produce maximal hyperemia and dipyridamole ha...
متن کاملAdenosine-induced atrial fibrillation during fractional flow reserve measurement.
We present the case of a 44 year-old man referred for coronary angiography with a history of coronary artery disease. Following administration of intra-coronary adenosine for fractional flow reserve (FFR) assessment, the patient developed atrial fibrillation (AF). While well described during non-invasive stress testing, this is the first description in the literature of AF following adenosi...

An ideal coronary vasodilator for studying coronary flow reserve in humans would rapidly produce maximal coronary vasodilation, be short acting to permit repeated measurements, and not alter systemic hemodynamics.

متن کاملCoronary vasodilator reserve. Comparison of the effects of papaverine and adenosine on coronary flow, ventricular function, and myocardial metabolism.
To evaluate coronary flow reserve during cardiac catheterization, intracoronary adenosine and papaverine have been used in the clinical setting. Although papaverine maximizes coronary blood flow, it induces several toxic side effects that reduce its desirability as a coronary dilator. This investigation was designed to compare the subselective intracoronary administration of papaverine with tha...
متن کاملIs coronary flow reserve in response to papaverine really normal in syndrome X?
BACKGROUND An impaired coronary flow reserve in syndrome X has been demonstrated by many studies. Recently, however, a normal coronary flow reserve in response to papaverine was reported, but the number of patients in these studies was small. The aim of this study was to investigate whether coronary flow reserve in response to intracoronary papaverine is really impaired in syndrome X. METHODS...
