RESUMO
Herein, we report a case of severe coronary spasm during cardiac catheterization refractory to medical management. Although this condition is usually managed with vasodilating agents, our patient ultimately required placement of stents.
RESUMO
Embolic protection devices are used to minimize the risk of stroke by preventing the migration of emboli during carotid artery stenting (CAS). After the successful conclusion of the CAS procedure, these devices are meant to be retrieved. Sometimes retrieval of the filter can be difficult. This difficulty in retrieval can be due to multiple factors such as incomplete stent expansion, stent fracture, vasospasm, and vessel tortuosity causing pseudostenoses. In this case report, an under-expanded proximal carotid stent strut contributed to the filter not being retrievable in spite of maneuvers to retrieve the filter. An innovative approach was used; a coronary guide extension catheter was used to enhance support and balloon-assisted tracking of the extension catheter then permitted advancement of the retrieval device and ultimate retrieval of the filter. This technique to retrieve a carotid filter has not been previously described in the literature.
RESUMO
A case is presented of a 65-year-old male who presented with an acute anterior wall myocardial infarction. An initial coronary angiogram demonstrated an ulcerated atherosclerotic plaque in the left main coronary artery. After 48 h of aggressive medical therapy including a 2b3a glycoprotein blocking agent, repeat angiography demonstrated resolution of the ulcerated plaque. The process of atherosclerotic plaque rupture is of dynamic nature.
