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.

The Focal Induction of Reactive Oxygen Species in Rats as a Trigger of Aortic Valve Degeneration.

Background: Degenerative aortic valve disease (DAVD) is a multifactorial process. We developed an animal model to analyze the isolated, local effect of reactive oxygen species (ROS) on its pathophysiology.

Methods: We utilized a photodynamic reaction (PDR) as a source of ROS in the aortic valve by aiming a laser at the aortic valve for 60 min after the administration of a photosensitizer 24 h prior.

Multiple Arterial Grafting During Coronary Artery Bypass Graft Surgery in Diabetic and Non-Diabetic Patients: A Short- and Long-Term Analysis at a Single Center.

: Coronary artery bypass surgery (CABG) with multiple arterial grafting (MAG) has shown potential to improve patient survival compared to single arterial bypass grafting. Whether this superiority in survival also exists in diabetics is uncertain. We therefore aimed to compare short and long-term outcomes of MAG in diabetic versus non-diabetic patients.

Left Ventricular Assist Device Implantation with Concomitant Replacement of the Ascending Aorta.

Dilated cardiomyopathy (DCM) is one of the main causes for end-stage heart failure. Until the transplantation, left ventricular assist devices (LVAD) have become an established treatment. We report a case of a 66-year-old patient with ischemic and DCM and suspected aortic ulcer formation.

Durable left ventricular assist devices following temporary circulatory support on a microaxial flow pump with and without extracorporeal life support.

Background: Circulatory support with a catheter-based microaxial flow pump (mAFP) plays a major role in the treatment of severe cardiogenic shock. In most patients who fail to recover while on temporary mechanical circulatory support (tMCS) and who are not eligible for heart transplantation, durable left ventricular assist device (dLVAD) implantation is usually considered a reliable option. This study aimed to describe the outcome of dLVAD therapy following mAFP support and to identify predictors of mortality.
