Characteristics of abnormal post-stent optical coherence tomography findings in hemodialysis patients

Original Research | By Matsuhiro Y, Matsunaga-Lee Y, Nakamura D et al.

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. ...

The Prevalence of Myocardial Bridging Associated with Coronary Endothelial Dysfunction in Patients with Chest Pain and Non-Obstructive Coronary Artery Disease

Original Research | By Sara JDS, Corban MT, Prasad M et al.

AIMS - Myocardial bridging (MB), characterized by the epicardial coronary vessel diving into the myocardium, is present up to 1/3rd of adults and is associated with accelerated atherosclerosis, and angina. In the current study we determine the association between MB and coronary endothelial dysfunction. METHODS AND RESULTS - Patients with chest pain and nonobstructive CAD (stenosis < 40%) at angiography un...

Fractional flow reserve derived from CCTA may have a prognostic role in myocardial bridging

Original Research | By Zhou F, Tang CX, Zhang LJ et al.

PURPOSE - To evaluate the feasibility of fractional flow reserve (cFFR) derivation from coronary CT angiography (CCTA) in patients with myocardial bridging (MB), its relationship with MB anatomical features, and clinical relevance. METHODS - This retrospective study included 120 patients with MB of the left anterior descending artery (LAD) and 41 controls. MB location, length, depth, muscle index, insta...
