“…Ages ranged from 23 years to 71 years; mean age 39.6 ± 19.8 years. Right-sided IE usually occurs in intravenous drug abusers or patients with human immunodeficiency virus [ 10 , 11 ], cardiac device infection, central venous catheter, congenital heart disease, and hemodialysis [ 8 ]. These risk factors may cause cardiac endothelial damage [ 9 ].…”

BackgroundInfective endocarditis (IE) is a rare disease with high mortality. Right-sided IE accounts for 5–10% of cases of IE. The tricuspid valve is most commonly affected, oppositely in coronary sinus (CS). The diagnoses, treatments and outcomes of CS vegetation has not been summarized yet.Case presentationWe present a 71-year-old man complained of cough and fever. Transthoracic echocardiography revealed the aneurysmal dilated CS with the band medium-echo mobile structure. A sinus venosus atrial septal defect has been detected. He had a persistent left superior vena cava which drained the right atrium via the aneurysmal dilated CS. Blood cultures were positive for Staphylococcus aureus. After intravenous antibiotic therapy, he had the symptom of dyspnea. The suspicious diagnosis is recurrent septic lung emboli which was confirmed by thoracic contrast enhanced computed tomography. The thoracotomy was performed to repair the atrial septum and remove the CS vegetation. Ten days later, the patient was discharged with only mild cough.ConclusionBoth positive blood cultures and echocardiography are major criteria in right-sided IE with CS vegetation. Current treatment options of CS vegetation include medical therapy and surgery. The surgical strategy for CS vegetation should be individualized, due to the controversial indications and optimum time of surgery. Most people have a good prognosis after proper treatment.Electronic supplementary materialThe online version of this article (10.1186/s12872-018-0845-x) contains supplementary material, which is available to authorized users.

In the intravenous drug user (IVDU) population, infected right-sided valvular lesions are common, and this has been well described in the literature. The Eustachian valve (also known as the valve of the inferior vena cava) is another valve in close proximity to the tricuspid valve, which can, in rare cases, be the focus of infection. Eustachian valve endocarditis may be an under-recognised complication of Staphylococcus bacteraemia in IVDU population, often only identified by transesophageal imaging. We present a case of tricuspid valve endocarditis in an IVDU with secondary seeding on the Eustachian valve, and an accompanying literature review on this rare topic.
