Abstract
Background and Clinical Significance: Hemophilia A presents a considerable challenge in cardiac surgery due to the elevated risk of perioperative bleeding, particularly during procedures involving cardiopulmonary bypass. Standard management typically involves standard half-life (SHL) factor VIII (FVIII) concentrates, which require frequent dosing. Extended half-life (EHL) FVIII products offer theoretical advantages, including prolonged action and reduced infusion frequency, but their use in cardiac surgery remains largely undocumented. Case Presentation: We report the case of a 73-year-old male with mild Hemophilia A who underwent successful aortic valve replacement using a 25 mm Carpentier-Edwards Magna Ease biological prosthesis. The patient was managed perioperatively with an anti-hemorrhagic protocol based on EHL recombinant FVIII. The surgery and postoperative course were uneventful, with no bleeding complications or need for transfusion. Conclusions: This case illustrates the potential role of EHL FVIII in safely managing hemophilic patients undergoing major cardiac surgery. Given the lack of existing reports in the literature, further studies are warranted to evaluate the efficacy and safety of EHL FVIII in this setting and to potentially optimize perioperative care protocols for this patient population.
