Background: The use of mechanical circulatory support devices for high-risk percutaneous coronary intervention (PCI) has increased over the past decade despite limited data of benefit. We sought to examine the association between intravascular microaxial left ventricular assist device (LVAD) versus intra-aortic balloon pump use in patients without cardiogenic shock (CS) undergoing PCI.
Methods And Results: This retrospective study analyzed claims data from a large, insured population who underwent PCI without CS from April 1, 2016 to July 31, 2022.
Aspirin and Hemocompatibility After LVAD Implantation in Patients With Atherosclerotic Vascular Disease: A Secondary Analysis From the ARIES-HM3 Randomized Clinical Trial.

Brigham and Women's Hospital Heart and Vascular Center, Center for Advanced Heart Disease, Harvard Medical School, Boston, Massachusetts.
Importance: The Aspirin and Hemocompatibility Events With a Left Ventricular Assist Device in Advanced Heart Failure (ARIES-HM3) study demonstrated that aspirin may be safely eliminated from the antithrombotic regimen after HeartMate 3 (HM3 [Abbott Cardiovascular]) left ventricular assist device (LVAD) implantation. This prespecified analysis explored whether conditions requiring aspirin (prior percutaneous coronary intervention [PCI], coronary artery bypass grafting [CABG], stroke, or peripheral vascular disease [PVD]) would influence outcomes differentially with aspirin avoidance.
Objective: To analyze aspirin avoidance on hemocompatibility-related adverse events (HRAEs) at 1 year after implant in patients with a history of CABG, PCI, stroke, or PVD.
Inflammatory and Hemolytic Responses of Microaxial Flow Pump Temporary Ventricular Assist Devices via Axillary Access in Cardiogenic Shock.

The use of temporary left ventricular assist devices (tLVADs) for patients suffering from cardiogenic shock (CS) is becoming more common. This study examines the indications and outcomes of microaxial flow pumps (Impella, Abiomed Inc., Danvers, MA, USA) when cannulated through the axillary artery in patients with severe CS, with a particular focus on acute phase reactions and hemolytic responses.

- Patients awaiting heart transplants often require colonoscopies due to bleeding or screening needs, but there's limited research on the safety of these procedures for individuals on inotropic medications or mechanical circulatory support.
- A study was conducted from 2015 to 2021 with 92 heart failure patients undergoing colonoscopy while on advanced heart failure therapies, such as inotropes or mechanical devices.
- Results indicated that the most common reason for colonoscopy was cancer screening, with significant findings including 8% of screening procedures revealing advanced adenomas and 17% of bleeding-related colonoscopies identifying sources needing intervention, but no major complications related to anesthesia were reported.
Assessment of Platelet Response to Aspirin Therapy and Hemocompatibility-Related Adverse Events in HeartMate 3 Left Ventricular Assist Device Recipients.
J Clin Med

: Patients with a HeartMate 3 (HM3) left ventricular assist device (LVAD) typically receive anticoagulation and antiplatelet therapy. The HM3 has shown a marked reduction in hemocompatibility-related adverse events (HRAEs) like stroke, bleeding, and pump thrombosis. This study evaluated whether aspirin (ASA) response influences HRAE incidence and if ASA sensitivity changes over time in HM3 recipients.
