Generally, early exercise after coronary stenting is considered safe, but isolated cases of acute stent thrombosis have been associated with the performance of a treadmill exercise test after percutaneous coronary intervention (PCI). The treadmill exercise test is often used to noninvasively assess the functional result of PCI. In this report, we describe a case of terrible stent thrombosis related to an exercise test performed 3 days after stenting, and the patient died as the result of an intractable thrombus.
Percutaneous coronary intervention (PCI) of stumpless chronic total occlusion (CTO) lesions with a side branch stemming from the occlusion have a significantly lower treatment success rate because physicians cannot identify an accurate entry point with only conventional angiographic images. An intravascular ultrasonography (IVUS)-guided wiring technique might be useful for the penetration of stumpless CTO. We recently experienced thrombotic occlusion during an IVUS-guided stumpless CTO procedure. The cause of the thrombosis is not completely understood; the thrombosis may have been associated with the long use of the IVUS catheter. Special precautions should be taken to prevent thrombus in such cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
