Background: The association between coronary microcirculation and clinical outcomes in patients with intermediate stenosis remains unclear.
Objectives: The aim of this study was to assess the prognostic significance of angiography-derived index of microcirculatory resistance (angio-IMR) in patients with intermediate coronary stenosis.
Methods: This post hoc analysis included 1,658 patients from the FLAVOUR (Fractional Flow Reserve and Intravascular Ultrasound for Clinical Outcomes in Patients with Intermediate Stenosis) trial, with angio-IMR measured in each vessel exhibiting intermediate stenosis.

Background: Geographic stent-ostium mismatch is an important predictor of target lesion failure after percutaneous coronary intervention of an aorto-ostial right coronary artery lesion. Optimal visualization of the aorto-ostial plane is crucial for precise stent implantation at the level of the ostium. This study investigates whether preprocedural 3-dimensional computed tomography (3DCT), with determination of the optimal viewing angle, would allow for more precise stent implantation and reduce procedure time, contrast, and radiation dose.

However, CTO-PCI encounters challenges such as undersized stents, dissection risks, and limited access to intravascular imaging (IVI), particularly in regions with limited health budgets. This study introduces the 'GIVE IT TIME TO SOBER UP - GITSU strategy', a two-session CTO-PCI approach where Thrombolysis in Myocardial Infarction (TIMI-3) antegrade flow is achieved without stent placement in the first session.

Intravascular ultrasound (IVUS) provides precise anatomic information in coronary arteries including quantitative measurements and morphological assessment. To standardize the IVUS analysis in the current era, this updated expert consensus document summarizes the methods of measurements and assessment of IVUS images and the clinical evidence of IVUS use in percutaneous coronary intervention.

In 2021, CMS waived the "substantial clinical improvement" criterion for devices designated under the FDA Breakthrough Devices Program (BDP). This study characterized risk-standardized payments associated with hospitalizations in which Medicare beneficiaries received calcium modification during PCI for acute myocardial infarction (AMI) following the adoption of the Shockwave C Coronary Intravascular Lithotripsy (IVL) Catheter (Shockwave Medical) with BDP designation.
