Article Synopsis
- This study explores a new method for accurately calculating fractional flow reserve (FFR) using coronary angiography to better identify patients who need intervention.
- The research involved a comparison of this new FFR framework against traditional wire-based FFR in 160 patients, revealing strong diagnostic performance metrics, such as a sensitivity of 79.3% and specificity of 95.4%.
- A key finding was the identification of longitudinal vorticity as a significant hemodynamic marker indicating the risk of major adverse cardiac events in patients who haven't undergone revascularization.
Background: There has been increasing use of transradial access (TRA) for non-chronic total occlusion (CTO) percutaneous coronary intervention (PCI). There are limited data on TRA for CTO PCI. The objectives of this study were to assess the temporal trends in the use of TRA versus transfemoral access (TFA), identify procedural and lesion characteristics associated with the use of TRA and TFA, and evaluate the association of access site with procedural complications and technical success among veterans undergoing attempted CTO PCI.

We sequenced the genomes of 21 strains representative of the global diversity and six major lineages of the M. tuberculosis complex (MTBC) at 40- to 90-fold coverage using Illumina next-generation DNA sequencing.
