Isolated Right-Sided Valvular Endocarditis in Non-Intravenous Drug Users

Right-Sided Endocarditis in a Non-Drug Addict

“…(5) If peripheral manifestations are present, an associated left-sided endocarditis or a paradoxical embolism should be suspected. (3) DUKE's criterion is not sensitive in diagnosing Rightsided Infective endocarditis. (4) Echo can be negative in 15% of infective endocarditis.…”

“…A high index of clinical suspicion in a patient with risk factors to develop right-sided IE is required for diagnosis. (3) Most common predisposing factor for right-sided endocarditis is IV catheter related infection and intravenous drug abuse is the second most common cause. In about 80 percent of the cases, tricuspid valve is involved.…”

“…Streptococci and Enterococci are the next most common pathogens. (3) Right-sided Infective endocarditis should be considered in any patient with fever, respiratory symptoms (Especially Multilobar consolidation), immunosuppressed background and staphylococcal septicaemia in absence of signs of systemic embolisation seen in left-sided IE. Diagnosis can be grossly delayed, since right-sided murmurs often go undetected, while peripheral stigmata are absent.…”

Iatrogenic Right Sided Infective Endocarditis in Children with CHD

“…The majority of cases involve tricuspid valve and pulmonary valve [3,4]. Characteristic of isolated right sided IE in patients without a pacemaker and who are not intravenous drug users are poorly understood [5]. In this small series of four cases, we report children with involvement of the right sided IE secondary to IV lines used for injections and IV fluids.…”

Chest radiographs as predictors of length of stay in right-sided infective endocarditis

“…1,2 It is usually a consequence of intravenous drug use (IVDU) and involves the tricuspid valve rather than the pulmonic valve. [3][4][5] Patients with right-sided IE can have septic emboli in the lung and develop septicemic pneumonia, pulmonary infarcts, lung abscesses, bilateral pneumothoraces, and empyema.…”
