Infective Endocarditi 67 year-old man with known long-standing mitral valve regurgitation presented with a recent decrease in effort tolerance with shortness of breath. He reports no fever, night sweats, or weight loss. He had recent dental work, with extraction of 14 teeth, and received 1 week of amoxicillin therapy for prophylaxis. Shortly after presentation, a transthoracic echocardiogram showed myxomatous changes of the anterior mitral valve leaflet. The appearance and motion was felt to be consistent with ruptured cords leading to a partial flail leaflet and severe mitral valve regurgitation. He therefore underwent elective mitral valve repair. Tissue was sent to pathology for examination. Cultures were not performed.
Case 33 Image Linear Sinusoidal Deposits in the Liver: Differential Diagnosis and Diagnostic Techniques A 68 year-old man presented with chronic recurrent pleural effusions.
