Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents (ADAPT-DES) was a prospective, multicenter registry of 8,582 consecutive stable and unstable patients who underwent percutaneous coronary intervention using a drug-eluting stent. We sought to identify key morphologic features leading to ST-segment elevation myocardial infarction (STEMI) versus non-STEMI (NSTEMI) or unstable angina pectoris (...

OBJECTIVES - The aim of this study was to determine the best threshold of postintervention minimum stent area (MSA) assessed by optical coherence tomography (OCT) to predict long-term in-stent restenosis (ISR) for 2.5 mm-diameter everolimus-eluting stents (EES). BACKGROUND - Percutaneous coronary intervention (PCI) for small coronary arteries remains challenging. Stent underexpansion ...

AIMS - The prognostic implications of periprocedural myocardial infarction (PMI) after percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) remain controversial. We examined the 3-year rates of mortality among patients with and without PMI undergoing left main coronary artery intervention randomized to PCI with everolimus-eluting stents vs. CABG in the large-scale, multicentre, prospective, ran...

OBJECTIVE - To use optical coherence tomography (OCT) and intravascular ultrasound (IVUS) in assessing myocardial bridging (MB) vessel size and wall thickness. BACKGROUND - During stent implantation, MB is associated with complications, especially perforation. METHODS - OCT and IVUS were performed in 56 patients with typical angiographic "milking" from N...
Assessment and Quantitation of Stent Results by Intracoronary Optical Coherence Tomography
Review Article | By Maehara A, Matsumura M, Mintz GS.
Optical coherence tomography evaluation of poststent results includes stent expansion as the absolute minimum stent area ratio by comparing the minimum stent area with the proximal and distal reference lumen areas or mean stent area defined as the total stent volume divided by the analyzed stent length; stent strut malapposition defined when the distance from the center of the blooming artifact and the surface of plaque is greater than the sum of...

AIM - Clinical outcomes after percutaneous coronary intervention (PCI) in hemodialysis (HD) patients are significantly worse than those in non-HD patients. Optical coherence tomography (OCT) is a high resolution imaging modality and provides a detailed assessment of post-interventional abnormal findings that influence worse clinical outcomes. However, little is known about the abnormal post-stent OCT findings in HD patients. T...
Intravascular Ultrasound Assessment of In-Stent Restenosis in Saphenous Vein Grafts
Original Research | By Wolny R, Mintz GS, Maehara A et al.
Outcomes after percutaneous coronary interventions (PCI) in saphenous vein grafts (SVG) are inferior compared with native coronary arteries, but the mechanisms of SVG in-stent restenosis (ISR) have not been well-described. Thus, we aimed to evaluate the patterns of SVG ISR using intravascular ultrasound (IVUS) in 54 SVG ISR lesions. Stent underexpansion was defined as minimum stent area (MSA) <5 mm2. ...
