ABSTRACT Background Intravascular ultrasound (IVUS)‐guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post‐PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively).

Analysis of atherosclerotic plaque distribution in the carotid artery
Abstract Background The present study was designed to investigate the hypothesis that the outer wall at the carotid bifurcation is the most common area of atherosclerotic plaque deposition due to the low shear stress. Hypothesis We hypothesized that the most common site of arteriosclerosis in carotid arteries is different in the early and late stages ...

ABSTRACT Background Lipoprotein(a) [Lp(a)] is associated with increased cardiovascular risk, but its influence on plaque characteristics at optical coherence tomography (OCT) evaluation is not fully understood. Aims This study seeks to explore the impact of Lp(a) levels on plaque morphology as assessed by OCT in a very high‐risk subset of patients ...

Abstract Radial artery spasm (RAS) is the most common cause of transradial access site crossover and is a common intra‐procedural complication. RAS incidence can lead to radial artery occlusion (RAO) postprocedure, preventing the radial artery as a future access site.

ABSTRACT Background Angulation of virtual basal ring (VBR), also known as aortic annulus, in relation to sino‐tubular junction (STJ) may lead to greater exposure of implanted stent to the conduction system, consequently increasing the risk of left bundle branch block (LBBB).

ABSTRACT Severe tricuspid regurgitation (TR) is associated with significant morbidity and mortality. Management of severe TR includes treatment of the underlying cause(s), medical therapy and less commonly surgical tricuspid valve repair. Newer transcatheter tricuspid valve repair devices show promise for those patients who remain symptomatic with ...
