Conclusion:
As we understood Q fever-induced endocarditis usually does not present with specific clinical manifestations and echocardiographic evidence, therefore early diagnosis and proper treatment are generally delayed. This mismanagement leads to different complications and increases the morbidity and mortality rate. According to the endemic distribution of Q fever in various regions, clinicians must consider any suspicious animal contact and keep this diagnosis in mind. We can decrease the diagnostic delay by making the laboratory tests available and performing rapid diagnostic tests for those with a history of animal contacts or other complicated underlying conditions.
