Biventricular Native Valve Endocarditis in a Patient with No Cardiac Disease and Predisposing Factor - Case Report.

Background: Infective endocarditis is a challenging clinical situation that causes numerous complications. Multi-valvular endocarditis, which is seen less frequently than single valvular endocarditis, is often a fatal disease. In this article, we present a case of endocarditis with native mitral and tricuspid valve involvement in a patient without any underlying predisposing factors. Case report:A 62-year-old patient was admitted to hospital with shortness of breath without any underlying predisposing factors. Covid-19 PCR swab was negative. Transthoracic echocardiography revealed bi-sided valve endocarditis with mitral and tricuspid valve involvement. The patient was taken to the intensive care unit. Transthoracic and transesophageal echocardiography revealed valvular involvement, flail mitrale with severe regurgitation on both valvules. The patient and patient's relatives refused the valvular operation because of the higher risk. Despite the antibiotic treatment, the general condition of the patient deteriorated and died. Conclusion:Multi-valvular endocarditis is a serious disorder with high mortality. In diagnosis, imaging procedures should be utilized as early as possible. Staphylococci are the most common pathogens in such cases, in which early diagnosis and treatment, particularly using a surgical approach, are appropriate.
