C41. Echocardiography Assessment of Aortic Native Valve Infective Endocarditis Complicated with Anterior Mitral Leaflet Abscess

Infective endocarditis (IE) presents a major therapeutic challenges due to difficulties in diagnosis and a high risk of morbidity. Despite numerous complications of IE, reported cases complicated by abscesses on the heart valve leaflets were extremely rare as illustrated in this case report

A 46-year-old man was admitted with severe shortness of breath since August 14, 2020. The patient also had cough and fever, emerging since 1 month before hospitalized. A history of PND, orthophnea, and DOE was experienced since the 1 month ago. Upon physical examination, abnormal findings include: tachycardia, tachypnea, visible and diastolic murmur at the right second intercostal alongside the parasternal line and systolic murmur at apex, respectively, as well as ronchi at 2/3 of the lung bases. Electrocardiogram revealed both sinus tachycardia and anteroseptal ischemia. An echocardiography was performed; thereby generating a vegetation at RCC and NCC of aortic valve, pocket-shaped echodense structure on anterior mitral leaflet with suspected abscess.

Definite infective endocarditis was navigated depicting the suspicion of: a vegetation in the aortic valve of NCC and RCC diagnosis, an abscess of the anterior mitral valve and ADHF of B profile with a potential of VHD and CAD with severe aortic valve regurgitation.
