On the other hand, occasionally, patients may have acute ischemia due to complete occlusion of an epicardial artery, but their ECG may show minor degree of ST elevation. Moreover, certain distinct ECG patterns have been described in patients presenting without ST elevation that are associated with...
and location of thecoronary artery occlusion. Animal models of MI can be achieved by direct occlusion of coronary artery using either reversible hydraulic occluder or ligation. Numerous studies from different species including, mice, rat, rabbit, dog, pig, and nonhuman primates, have been ...
those most likely to rupture and evolve into a complete thrombotic occlusion, are those with large lipid cores and thin fibrous caps.5Most of the plaques with the largest lipid cores are not severely stenotic (the lipid-laden deposits enlarge the artery and do not always reduce the area of ...

THE HIGH mortality which has been associated with the conventional methods of treatment of acute coronary occlusion associated with shock1has stimulated consideration of surgical treatment for the lesion. Indeed, clinical attempts to remove acute coronary artery obstruction have already been made on a fe...

Below is an ECG with changes of an acute anterio-lateral infarct with ST-elevation in V1-V4 as well as I and AVL: 2. Posterior STEMI, usually associated with occlusion of an anatomically dominant right coronary artery, may present with ST segment depression in V1 to V3 instead...
Data on the prevalence of conus branch artery (CBA) is scarce, and its utilization in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) is non-existing. The present study examined carefully in a large cohort the angiographic prevalence of CBA, its role as a collateral ...
thrombotic occlusion as graft size decreases.15When used for bypass procedures in thearterial circulation, prosthetic vascular graft function is adequate for use in large-diameter grafts (>8mm, such as for use in aortic surgery), intermediate (between 6 and 8mm, such as femoralartery bypasssurgery...
