Non-bacterial thrombotic endocarditis: A state-of-the-art contemporary review

Abstract

Non-bacterial thrombotic endocarditis (NBTE), also known as Libman-Sacks, marantic, thrombotic, or verrucous endocarditis, is a form of non-infective endocarditis that affects cardiac structures in patients who have predisposing underlying conditions.¹ As it is rarely encountered in routine clinical practice, the condition may be overlooked or misdiagnosed. On the other hand, other similar clinical entities might be erroneously labeled as NBTE. Notwithstanding its ostensibly uncommon appearance in clinical practice, our understanding of NBTE has been expanding, especially with the advent of modern and advanced diagnostic tools that facilitate the evaluation process. Herein, we provide a comprehensive review of NBTE, with a focus on the contemporary diagnostic evaluation and management.
