Mitral Valve Aneurysm Secondary to Probable Infective Endocarditis

We report the case of a 54-year-old male with a history of chest trauma in 2011, complicated by bacteremia caused by methicillin-sensitive Staphylococcus aureus (MSSA). In 2012, the patient was diagnosed with spondylodiscitis, and in 2013, he was referred to cardiology for dyspnea. Transthoracic echocardiography (TTE) showed an aneurysm of the posterior leaflet of the mitral valve. Transesophageal echocardiography (TEE) confirmed the presence of the aneurysm, which caused severe valvular insufficiency.

Although infective endocarditis was never confirmed, after reviewing his medical records, the authors concluded that this condition was probably associated with mitral valve aneurysm.
