Optical Coherence Tomography–Guided Percutaneous Coronary Intervention in ST-Segment–Elevation Myocardial Infarction
The culprit lesion in ST-segment–elevation myocardial infarction (STEMI) is usually occluded, thrombotic, and subject to vasospasm. These factors can make adequate sizing and deployment of stents in STEMI more challenging than in other clinical settings. Patients with STEMI are at high risk of adverse cardiac outcomes that may be improved with more complete stent apposition and expansion. These...
متن کاملacute st-elevation myocardial infarction after coronary stent fracture
the invention of the drug-eluting stent (des) has brought about revolutionary changes in the field of interventional cardiology. in the des era, in-stent restenosis has declined but new issues such as stent thrombosis have emerged. one of the emerging paradigms in the des era is stent fracture. there are reports about stent fracture leading to in-stent restenosis or stent thrombosis. most of th...
متن کاملOptical coherence tomography assessment of in vivo vascular response after implantation of overlapping bare-metal and drug-eluting stents.
OBJECTIVES We designed a randomized trial exploiting optical coherence tomography (OCT) to assess coverage and apposition of overlapping bare-metal stents (BMS) and drug-eluting stents (DES) in human coronary arteries. BACKGROUND Overlapping DES impair healing in animals. Optical coherence tomography allows accurate in vivo assessment of stent strut coverage and apposition. METHODS Seventy-...
متن کاملOptical coherence tomography findings in ST-elevation acute myocardial infarction in a young woman.
A27-year-old African woman was admitted to our ICU care with chest pain. STelevation was present in leads II, III and aVF and cardiac troponin T was elevated (0.74 ng/ml). Urgent coronary angiography was performed which revealed a 70% proximal lesion in the LAD artery suggestive of intracoronary thrombus (Figure 1). No other lesions were present. Intravascular optical coherence tomography (OCT)...
متن کاملThe invasive assessment of coronary atherosclerosis and stents using optical coherence tomography: a clinical update
Ischaemic heart disease (IHD) remains one of the leading causes of death. Atherosclerosis has been intensely researched given the IHD prevalence and the financial impacts on healthcare systems. More recently, in vivo characterisation of coronary atherosclerotic plaque and tissue responses following stent implantation in a coronary artery has been made possible by a novel technology called optic...
