It has been reported that some patients have been misdiagnosed with Aortic Valve Insufficiency, when in fact the correct diagnosis in their specific case was Endocarditis.
Endocarditis is an infection of the inner tissue lining of your heart which is caused by an infection. Symptoms of endocarditis include chest pain when breathing, fatigue, fever, shortness of breath. Due to how vague these symptoms are it can be mistaken for many respiratory diseases, rheumatoid arthritis, or generalised infections and makes early diagnosis of endocarditis is difficult. Without early treatment of endocarditis with antibiotics the condition will certainly lead to death.
