VEGA, Julián et al. Cleft of the posterior mitral valve leaflet simulating a three leaflet valve. Rev Chil Cardiol [online]. 2015, vol.34, n.3, pp.202-206. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602015000300006.

We report the case of a 55 year old woman, previously treated with antibiotics for periodontitis. She was admitted with fever and lumbar pain. An elevated C reactive protein (CRP) and positive blood cultures for Streptococcus Viridans were found and infectious spondylodiscitis of L5-S1 was confirmed. Transeso-phageal echocardiography (TEE) was performed. A tri-leaflet mitral valve and prolapse of posterior leaflet (P2-P3) were found and severe mitral regurgitation was present on doppler examination In addition, a left atrial mural vegetation (jet lesion) was found. At cardiac surgery mitral valve repair and resection of the mural vegetations were performed. The papillary muscles were normal, and this tri-leaflet aspect of the mitral valve was interpreted as a deep posterior cleft with symmetrical distribution of all remaining segments.

Palabras clave : Endocarditis; Mitral valve prolapse; mitral valve insufficiency.
