Fungal endocarditis is caused mainly by Candida albicans and Aspergillus spp. and was first reported in the 1950s. Natural-valve endocarditis caused by Aspergillus is relatively uncommon. In this case, a 56-year-old male patient was admitted to the hospital on account of a cough accompanied by chills and fever and ineffective self-medication. Infective endocarditis was initially suspected based on echocardiography (indicating right atrial growth) and clinical manifestations. However, routine pathogen detections were always negative. The patient's condition was identified as Aspergillus fumigatus endocarditis (AFE) and was treated with targeted therapy, considering the detection of significant AFE sequences in the blood through metagenomic next-generation sequencing (mNGS). On this basis, the paper further summarizes the clinical manifestations, diagnosis, treatments, and outcomes of AFE endocarditis cases reported in recent years, aiming to provide a reference to better understand this rare infective disease and guide medical practitioners in choosing the right diagnostic and therapeutic strategy.
