Case in brief
Two patients undergoing percutaneous transvalvular microaxial flow pump therapy developed hemolysis, which was identified through significantly elevated carboxyhemoglobin (CO-Hb) levels. The detection of these elevated levels provided an early indication of hemolysis, allowing for timely intervention. The cases suggest that CO-Hb can be a useful bedside marker in this clinical setting.
Diagnostic / clinical pearl
Elevated carboxyhemoglobin levels may serve as an early indicator of hemolysis in patients supported by left ventricular assist devices.
Why it matters
Recognizing CO-Hb as a potential marker for hemolysis could enhance monitoring and management strategies in patients with extracorporeal circulation support.
