Regadenoson stress induced wall motion abnormalities during cardiac MRI
نویسندگان
چکیده
Methods Patients underwent regadenoson CMR that included 3 (basal, mid, apical) slices of rest and peak stress real-time cines, with matching stress and rest first-pass perfusion, and late gadolinium enhancement (LGE) imaging. The reference standard for presence or absence of CAD was derived from invasive coronary angiography or coronary CT angiography (CTA). Invasive angiography established significant CAD based on a threshold of ≥70% stenosis and could rule-in or exclude CAD. CTA was only used to exclude CAD if the calcium score was <100 and no stenosis was >30%; CT was not used to diagnose CAD. Two blinded, readers qualitatively scored RWM of pre and post-regadenoson.

Initial description of changes in wall motion parameters in normal subjects undergoing rest/regadenoson stress using a tagged MRI sequence
Background Changes in global and regional wall motion between rest and stress are important prognostic markers, uncommonly observed with vasodilator stress radionuclide myocardial perfusion imaging (MPI). Cardiac MRI (CMR) with tagging has the potential to more precisely quantify normal and abnormal ventricular wall motion responses. We herein report CMR findings in 5 very low-likelihood patien...

Background Transient ischemic dilation of the left ventricle may be suggestive of global myocardial ischemia on SPECT stress imaging. While SPECT stress/rest imaging relies on computation-adjusted volumetric data to calculate a stress/rest “TID ratio,” measured at 20 to 30 minutes after peak regadenoson stress, cardiac MRI (CMR) allows for the direct measurement of LV wall thickness and cavity ...

OBJECTIVES The purpose of our study was to conduct an evidence-based evaluation of stress cardiac magnetic resonance imaging (MRI) in the diagnosis of coronary artery disease (CAD). BACKGROUND Stress cardiac MRI has recently emerged as a noninvasive method in the detection of CAD, with 2 main techniques in use: 1) perfusion imaging; and 2) stress-induced wall motion abnormalities imaging. M...
متن کاملRapid detection of coronary artery stenoses with real-time perfusion echocardiography during regadenoson stress.
BACKGROUND Real-time myocardial contrast echocardiography permits the detection of myocardial perfusion abnormalities during stress echocardiography, which may improve the accuracy of the test in detecting coronary artery stenoses. We hypothesized that this technique could be used after a bolus injection of the selective A2A receptor agonist regadenoson to rapidly and safely detect coronary art...

Background Patients referred to cardiac MRI (CMR) for suspicion of obstructive coronary artery disease typically undergo vasodilator stress testing using either adenosine or regadenoson. Both of these agents are effective and have been evaluated for stress testing in both the CMR and nuclear medicine setting but the cardiovascular physiologic effects of each of these agents have not been well s...
