ABSTRACT
Parvimonas micra, a gram-positive anaerobic bacterium, has garnered increased attention due to its role in infective endocarditis. We present a challenging prosthetic valve endocarditis caused by Parvimonas micra in a patient with a complex cardiac history involving multiple surgeries. The case highlights the difficulties in diagnosis and treatment, emphasizing the importance of advanced diagnostic techniques, including metagenomics next-generation sequencing (mNGS). Additionally, it underscores the need for heightened vigilance regarding oral symptoms and the potential risk of bacteremia in post-valvular surgery patients. This report contributes to a better understanding of Parvimonas micra-associated endocarditis and its unique characteristics.
