The advent of intravascular imaging has been a significant advancement in visualization of coronary arteries, particularly with optical coherence tomography (OCT) that allows for high-resolution imaging of intraluminal and transmural coronary structures. Accumulating data support a clinical role for OCT in a multitude of clinical scenarios, including assessing the natural history of atherosclerosis and modulating effects of therapies, mechanisms of acute coronary syndromes, mechanistic insights into the effects of novel interventional devices, and optimization of percutaneous coronary intervention. In this state-of-the-art review, we provide an overview of the published data on the clinical utility of OCT, highlighting the areas that need further investigation and the current barriers for further adoption of OCT in interventional cardiology practice.

Transradial access offers important advantages over transfemoral access, including overall increased procedure comfort and better outcomes. Still, complications of transradial access exist, with radial artery occlusion being the most clinically relevant one. Puncture sites in the hand allowing distal radial artery access have initially been described for anterograde angioplasty of occluded radial arteries and could represent a valuable alternative to traditional wrist puncture for radial artery catheterization. What may at first appear as a “radialist eccentricity” definitely has a sound rationale, which the authors review. Knowledge of the anatomic and physiological principles at the basis of distal radial artery access is essential to promote rigorous understanding and practice of this new opportunity for both patients and interventional specialists.
