Fatal Complications in Candida parapsilosis Endocarditis—A Case Report

Fungal endocarditis, despite being a rare diagnosis, has a higher morbidity and mortality rate compared to bacterial endocarditis. Candida species are the most common isolated pathogens involved in fungal endocarditis. Diagnosis is suspected in patients with underlying conditions such as cancer, myelodysplastic syndrome, diabetes, or intravascular catheters, where the modified Duke criteria apply. Management of the patient requires a multidisciplinary team (cardiologist, infectious diseases consultant, cardiac surgeon) along with antifungal treatment. We present the case of a 60-year-old male with biological prosthetic aortic valve replacement in the previous year for bicuspid aortic stenosis, admitted for a 5-day history of fever, nausea and minor urinary symptoms. The blood cultures were positive for Candida parapsilosis. Transthoracic cardiac ultrasound revealed a hypoechogenic mass attached to the aortic valve at the prosthetic fixation site. Although diagnosis was rapidly confirmed and treatment was administered shortly after first suspected, the patient developed, at first, cavernous sinus thrombosis and, later, fatal ST elevation myocardial infarction. The patient died despite efficient antifungal therapy, initially with Anidulafungin in monotherapy and later in combination with Fluconazole. The reported case emphasizes the importance of managing fungal endocarditis, the need for urgent diagnostic attention and multidisciplinary team approach by infectious diseases specialist, cardiologist, neurologist and heart surgeon.
