Fiebre persistente tras intervencionismo hospitalario: endocarditis nosocomial en bioprótesis mitral.

The article titled "Persistent Fever after Hospital Intervention: Nosocomial Endocarditis in Mitral Bioprosthesis" describes the case of an 80-year-old woman with arterial hypertension, persistent atrial fibrillation, and a mitral bioprosthesis, who was diagnosed with late prosthetic endocarditis. The patient presented with refractory fever, dyspnea, asthenia, and a systolic mitral murmur. Blood cultures were negative, but the echocardiogram revealed a mass on the mitral prosthesis. After the diagnosis, the patient suffered an embolism in both lower extremities and a hemorrhagic stroke without sequelae. During surgery, a coraliform vegetation was found on the bioprosthesis and a new prosthesis was implanted. Cultures were positive for Candida parapsilosis and a full cycle of antifungals was administered without complications. After six months, the patient is asymptomatic. Fungal endocarditis in bioprostheses is uncommon and may be related to the use of catheters and intracardiac devices. [Extracted from the article]
