Article Abstract
Percutaneous coronary intervention is increasingly guided by coronary physiology and optimized using intravascular imaging. Pressure-based measurements determine the significance of a stenosis using hyperemic or nonhyperemic pressure ratios (eg, the instantaneous wave-free ratio). Intravascular ultrasound and optical coherence tomography provide cross-sectional and longitudinal detail regarding plaque composition and vessel characteristics. These facilitate lesion preparation and optimization of stent sizing and positioning. This review explores the evidence-base and practical aspects of coregistering pressure gradient assessment and intravascular imaging with angiography. We then discuss gaps in the evidence and what is needed to help integrate these techniques into clinical practice.

Background: Cardiac issues following radiotherapy are increasingly prevalent among patients with thoracic cancer and coronary disease. However, the mechanisms underlying radiotherapy-induced plaque instability and changes in plaque characteristics on imaging remain unclear. This study used single-cell RNA sequencing to identify key features of vulnerable plaques following radiotherapy.

A 33-year-old male developed pulmonary vein (PV) stenosis 3 months after PV isolation for atrial fibrillation. Stents were implanted in the left superior and inferior PVs, but 2 years later, in-stent restenosis occurred. Intravascular ultrasound and nonobstructive general angioscopy (NOGA) revealed severe ostial stenosis and neointimal hyperplasia.

Background: The clinical benefit of using ICT for coronary stent optimization remains uncertain in randomized trials, in which a unique ICT was used in most cases.
Aim: To assess the clinical impact of intracoronary techniques (ICT) for stent optimization in high-risk patients.
Methods: The OPTI-XIENCE study is a prospective, observational, multicenter international study including high-risk patients undergoing coronary stenting, in whom any ICT was used for stent optimization at the operator's discretion.
