Regional myocardial perfusion reserve determined using myocardial perfusion magnetic resonance imaging showed a direct correlation with coronary flow velocity reserve by Doppler flow wire.
AIMS Quantitative analysis of rest-stress myocardial perfusion magnetic resonance imaging (MRI) can provide assessments of regional myocardial perfusion reserve (MPR). The purpose of this study was to compare regional MPR determined by myocardial perfusion MRI with coronary flow reserve (CFR) by intracoronary Doppler flow wire. METHODS AND RESULTS Twenty patients with suspected coronary arter...
متن کاملValidation of collateral fractional flow reserve by myocardial perfusion imaging.
BACKGROUND Collateral fractional flow reserve (FFR(coll)) is an index to quantify collateral blood flow, derived from coronary pressure measurements. Although well defined theoretically, its direct validation by myocardial perfusion imaging has not been established so far. Validating this index by myocardial perfusion imaging is the main aim of this study. METHODS AND RESULTS Twenty-four cons...
متن کاملRelative coronary flow velocity reserve improves correlation with stress myocardial perfusion imaging in assessment of coronary artery stenoses.
STUDY OBJECTIVE To evaluate the angiographic and coronary flow velocity parameters that best correlate with the results of stress myocardial perfusion imaging. DESIGN Criterion standard. SETTING Tertiary care center. PATIENTS Forty-eight patients undergoing diagnostic coronary angiography for angina or silent ischemia. INTERVENTIONS We performed angiographic and coronary flow velocity m...
متن کاملNicorandil effect on myocardial perfusion in patients with slow coronary flow phenomenon assessment by gated myocardial perfusion SPECT
Introduction:Patients with the coronary slow flow phenomenon (SCF) frequently experience angina episodes. The purpose of this study was to determine efficacy of nicorandil in myocardial perfusion in patients with SCF. Methods: Twenty patients (50.85 ± 12.96 y) with SCF were studied. We evaluate coronary slow flow according to protracted thrombolysis in m...
متن کاملFeasibility and diagnostic power of transthoracic coronary Doppler for coronary flow velocity reserve in patients referred for myocardial perfusion imaging
BACKGROUND Myocardial perfusion imaging (MPI), using single photon emission computed tomography (SPECT) is a validated method for detecting coronary artery disease. Transthoracic Doppler echocardiography (TTDE) of flow at rest and during adenosine provocation has previously been evaluated in selected patient groups. We therefore wanted to compare the diagnostic ability of TTDE in the left anter...
