Infective endocarditis (IE) is a serious and potentially life-threatening condition characterized by infection of the endocardial surface of the heart, primarily affecting heart valves. This article reviews the impact of IE on heart valve integrity, discussing the pathophysiology, clinical manifestations, diagnostic challenges, and management strategies associated with this condition. By analyzing recent advancements and outcomes, we aim to highlight the importance of early diagnosis and effective treatment to preserve heart valve function and improve patient prognosis.
