Endocarditis: Rising Incidence in the Post-COVID-19 Pandemic Era: A Narrative Review

: Infective Endocarditis (IE) incidence has increased in recent years, driven by emerging risk factors affecting both elderly and young adults. Also, the role of Non-Bacterial Thrombotic Endocarditis (NBTE) is gaining importance as it is a subtle, probably underdiagnosed entity. Moreover, the COVID-19 pandemic has influenced the epidemiology of endocarditis, raising questions about their relationship, diagnosis, and management. Diagnosis of IE is sometimes challenging, and classic criteria are now being rediscussed. The aim of our study is to provide a narrative review about how and why IE incidence is rising, the role of NBTE, the impact of the COVID-19 pandemic on endocarditis patterns, and the current diagnostic challenges we face in the post-pandemic era.
