Optimal Intravascular Ultrasound-Guided Percutaneous Coronary Intervention in Patients with Multivessel Disease and Chronic Kidney Disease.

There is a scarcity of data on clinical outcomes after intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with multivessel disease and chronic kidney disease (CKD). The OPTIVUS-Complex PCI study multivessel cohort was a prospective multicenter single-arm trial enrolling 1015 patients who underwent multivessel IVUS-guided PCI including left anterior descending coronary artery target with an intention to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared the clinical outcomes between patients with and without CKD.

Association of Baseline Mitral Valve Area With Procedural and Clinical Outcomes of Mitral Transcatheter Edge-to-Edge Repair: Insights From the OCEAN-Mitral Registry.

Background: A small mitral valve area (MVA) is one of the challenging anatomies for transcatheter edge-to-edge repair (TEER) for mitral regurgitation, but the relationship between baseline MVA and clinical outcomes remains unknown. This study aimed to evaluate the association of baseline MVA with procedural and clinical outcomes in patients undergoing TEER with MitraClip from the OCEAN-Mitral registry (Optimized Catheter Valvular Intervention-Mitral).

Methods: A total of 1768 patients undergoing TEER were divided into 3 groups according to baseline MVA: group 1: <4.

Heparin Reversal for Coronary Artery Perforation.

Background: Reversing heparin when managing coronary artery perforation (CAP) during percutaneous coronary intervention (PCI) can provide hemostasis but may cause coronary thrombosis if a device is still present in a coronary artery.

Aims: To assess the impact of heparin reversal while an intracoronary artery device is in place for CAP.

Methods: This study analyzed CAP cases during PCI from January 2006 to October 2023.

Mechanically induced polyamorphism in a one-dimensional coordination polymer.

We created different amorphous structures of a coordination polymer by applying mechanical shear forces. One-dimensional Cu(TfN)(bip) (1, TfN = bis(trifluoromethanesulfonyl)imide, bip = 1,3-bis(1-imidazolyl)propane) melted at 245 °C and underwent a glass transition at -10 °C by a static cooling process. 1 formed another amorphous state with a distinct glass transition point of 70 °C under oscillatory shear stress.

Impact of Angiographically Detected Residual Trabeculation After Left Atrial Appendage Closure Using the WATCHMAN Device: Insight From the OCEAN-LAAC Registry.

Background: Research on the impact of angiographically detected residual trabeculation after left atrial appendage closure (LAAC) is limited.

Objectives: To investigate the incidence, characteristics, and clinical implications of angiographically detected residual trabeculation after LAAC using the WATCHMAN device.

Methods: We analyzed 1350 consecutive patients with atrial fibrillation undergoing LAAC using the WATCHMAN device from the OCEAN-LAAC registry, which is a prospective ongoing, multicenter Japanese registry.
