Candida parapsilosis endocarditis ın a patient with liver transplantation.

Infective endocarditis (IE) is caused by viral, bacterial or fungal pathogens, with high morbidity and mortality. Fungal endocarditis is rare and is associated with severe complications with poor prognosis despite combined medical and surgical treatment. Although Candida albicans is the most common fungal agent of this severe form of endocarditis, Candida parapsilosis is the most common non-albicans causative species. A 17-year-old patient who had had a liver transplant was referred to our paediatric cardiovascular surgery ward with a diagnosis of right heart failure. He had had coronary artery bypass graft and aortic valve replacement in 2021. He came to the outpatient clinic with complaints of fever, weakness, nausea and vomiting. On physical examination, he had pallor, dyspnoea and tachycardia. His fever was 38 °C and a grade 2/6 systolic ejection murmur was detected on auscultation. Amphotericin B in a dose of 4 mg/kg/day was started based on the antifungal sensitivity test.
