Readmission after coronary artery bypass surgery in women and men

Melanie Arnreiter, Alexandra Kaider, Philipp Angleitner, Marija Pljakova et autres

OBJECTIVES: Readmissions after coronary artery bypass grafting (CABG) are common and contribute substantially to long-term morbidity, yet extended follow-up data remain limited. Women experience higher perioperative morbidity, mortality, and short-term readmission rates than men, but long-term sex-specific patterns of readmission after CABG …

Hemocompatibility Outcomes After Aspirin Withdrawal in Long‐Term HeartMate 3 Left Ventricular Assist Device Patients on Vitamin K Antagonists

Melanie Arnreiter, Barbara Karner, Hebe Al Asadi, Christina Abd El‐Malak et autres

BACKGROUND: Left Ventricular Assist Devices, particularly Heart Mate 3 (HM3), have improved outcomes for advanced heart failure patients. Despite advancements, hemocompatibility-related adverse events (HRAEs) continue to pose significant challenges. Standard antithrombotic therapy combines vitamin K antagonists (VKAs) with aspirin, though the ARIES-HM3 …

The Commando procedure for mechanical double valve prosthesis endocarditis with destruction of the aortomitral continuity

Sami Mouritane, Birgit Zirngast, Melanie Arnreiter, Günther Laufer et autres

Infective endocarditis, particularly after implanting valve prostheses, poses significant surgical challenges, often requiring complex interventions. We describe a case of a 37-year-old male with Staphylococcus aureus endocarditis, unsuccessfully treated with mechanical valve prostheses. Continued infection led to the destruction of the intervalvular …
