Abstract
Right-sided infective endocarditis is an increasingly recognized disease entity, with tricuspid valve being most frequently involved. Risk factors for tricuspid valve endocarditis (TVIE) include intravenous drug use, cardiac implantable electronic devices and indwelling catheters. Staphylococcus aureus is the predominant causative organism in TVIE. The diagnosis of infective endocarditis (IE) is based on clinical manifestations, blood cultures, and the presence of valvular vegetations detected by echocardiography. Complementary imaging is helpful when there is ongoing clinical suspicion for IE following initially negative echocardiography. Multislice computed tomography allows for assessment of extra-cardiac complications in TVIE, including pulmonary septic emboli. 18F-fluorodeoxyglucose positron emission tomography/computed tomography and radiolabelled white blood cell, single-photon emission computed tomography provide important clinical information concerning the presence of IE in right-sided prosthetic valves or cardiac implantable electronic devices. The aim of this review is to provide an update on TVIE, discussing the role of multimodality imaging in TVIE and the management of these patients.
Core Tip: Right-sided infective endocarditis (RSIE) is an increasingly important subtype of infective endocarditis (IE), although less published literature is available regarding RSIE compared to left-sided IE. Recently, with improvements in multimodality imaging, there is an increasing role for imaging in the evaluation and management of tricuspid valve endocarditis (TVIE). We review the role of cardiac imaging in diagnosis and evaluation of TVIE, and provide a concise update on the management of these patients.
