Determinants of myocardial perfusion reserve measured from coronary sinus phase-contrast imaging during regadenoson stress CMR
Background Measurement of myocardial perfusion reserve (MPR) can potentially extend the scope of conventional myocardial perfusion imaging from detection of flow limiting epicardial stenosis to assessment of coronary microvascular function. Recent studies have suggested that MPR may improve risk stratification of patients with known or suspected CAD. MPR has traditionally been measured using PE...
متن کاملAssessment of global myocardial perfusion reserve using cardiovascular magnetic resonance of coronary sinus flow at 3 Tesla
BACKGROUND Despite increasing clinical use, there is limited data regarding regadenoson in stress perfusion cardiovascular magnetic resonance (CMR). In particular, given its long half-life the optimal stress protocol remains unclear. Although Myocardial Perfusion Reserve (MPR) may provide additive prognostic information, current techniques for its measurement are cumbersome and challenging for ...
متن کاملCombined Assessment of Stress Myocardial Perfusion Cardiovascular Magnetic Resonance and Flow Measurement in the Coronary Sinus Improves Prediction of Functionally Significant Coronary Stenosis Determined by Fractional Flow Reserve in Multivessel Disease
BACKGROUND Recent studies using stress-rest perfusion cardiovascular magnetic resonance (CMR) demonstrated a close correlation between myocardial ischemia and reduced fractional flow reserve (FFR). However, its diagnostic concordance may be reduced in patients with multivessel disease. We sought to evaluate the concordance of adenosine stress-rest perfusion CMR for predicting reduced FFR, and t...
متن کاملPatients with Cardiac syndrome X have decreased global myocardial perfusion compared to gender matched controls; insights from CMR coronary sinus flow measurements
Methods Thirteen CSX patients (64 ± 12SD years, 9 females), here defined as a history of chest pain and pathological ECG reaction during stress (> 1 mm ST-depression at stress or after 4 minutes of recovery) but normal myocardial perfusion assessed by myocardial perfusion scintigraphy (SPECT), were included. In addition, 15 positive controls (66 ± 9SD years, 6 females) with stress-induced perfu...
متن کاملArterial spin labeling CMR perfusion imaging is capable of continuously monitoring myocardial blood flow during stress
Background Myocardial arterial spin labeling (ASL) is a non-invasive non-contrast CMR perfusion imaging technique [Zun et al., ‘09] that is compatible with adenosine stress testing [Zun et al., ‘11]. Here, we demonstrate its ability to continuously monitor MBF during stress, which has a variety of potential applications including interventional CMR and the study of endothelial function. We used...
