Infective Endocarditis as a Complication of a Ventriculoatrial Shunt.

Area of Science:

• Cardiology
• Infectious Diseases
• Neurosurgery

Background:

• Congenital hydrocephalus often necessitates ventriculoatrial shunts.
• Ventriculoatrial shunts can be a source of bloodstream infections, including endocarditis.
• Infective endocarditis in patients with shunts presents a complex management challenge.

Purpose of the Study:

• To report a case of methicillin-sensitive Staphylococcus aureus endocarditis in a patient with a ventriculoatrial shunt.
• To emphasize the importance of early diagnosis and management of shunt-related endocarditis.
• To highlight the necessity of shunt removal in addition to antibiotic treatment.

Main Methods:

• Case presentation of a 31-year-old male with congenital hydrocephalus and a ventriculoatrial shunt.
• Diagnosis of infective endocarditis confirmed by blood cultures (methicillin-sensitive Staphylococcus aureus) and transesophageal echocardiogram.
• Treatment involved shunt removal and a 6-week course of oxacillin and rifampin.

Main Results:

• The patient presented with sepsis despite antibiotic treatment for bacteremia.
• Transesophageal echocardiogram identified vegetations on the tricuspid valve and shunt tip.
• Successful treatment was achieved with shunt removal and combination antibiotic therapy.

Conclusions:

• A high index of suspicion for endocarditis is critical in patients with ventriculoatrial shunts.
• Management of ventriculoatrial shunt-related endocarditis requires surgical intervention (shunt removal) alongside appropriate antibiotic therapy.
• This approach aligns with established protocols for cardiac device-related infective endocarditis.
