from MRI scans, offering a potential new noninvasive assessment method in
patients with poor echocardiograms.
Magnetic

with slide / Magnetic resonance angiography can be used not only to
detect the presence or absence of graft patency following CABG, but also to
determine the extent of stenosis in the vessel, researchers say. The test may
one day provide a noninvasive tool for determining whether a patient with angina
post-CABG does indeed have something to worry about.
Subendocardial
ischemia detected in patients with cardiac syndrome X
Panting JR et al, Panza JA.
N Engl J Med 2002;346:1948-1953, 1934-1935. [ Jun 19, 2002 ]
MRI studies show decreased subendocardial, but normal transmural, perfusion
during stress with adenosine, leading researchers to conclude that an unusual,
localized ischemia may be at the heart of angina associated with the mysterious
cardiac syndrome X. But an editorialist remains unconvinced ischemia is the key.

Coronary Artery Patency After Metallic Stent
Implantation Evaluated by Multislice Computed Tomography
Nobusada Funabashi et al
Circulation 2003;107 147-148

Four months after the stent placement, ECG-gated enhanced multislice
computed tomography (CT) (Light Speed Ultra, General Electric) was performed
with a 1.25-mm slice thickness, helical pitch 3.25, to evaluate the coronary
artery lumen for restenosis at the stent implantation sites. After intravenous
injection of 100 mL of iodinated contrast material (350 mgI/mL), CT scanning was
performed with retrospective ECG-gated reconstruction. After acquisition, volume
data were extracted from end-diastole, and volume-rendering images were
generated (M900 Zio). In the axial source image and cut-plane volume rendering
image, the patency of the coronary arterial lumen of the proximal portion of the
LAD surrounded by the metallic stent was observed without any artifact
from the metallic stent. The next day, conventional coronary angiography showed
no significant luminal stenosis of the proximal and distal portions of the LAD.
Magnetic resonance imaging demonstrates
improved regional systolic wall motion and thickening and myocardial perfusion
of myocardial territories treated by laser myocardial revascularization
Laham RJ, et al.

This small phase I, open-label, uncontrolled study of MR functional and
perfusion imaging in patients undergoing Biosense-guided LMR suggests a
beneficial effect of this treatment strategy on myocardial function and
perfusion. The efficacy of Biosense-guided LMR is being evaluated in a large
phase II, randomized, blinded placebo-controlled trial with an MRI substudy
(DIRECT).
