"Kissing abscess" de la valva anterior mitral y pseudoaneurisma por endocarditis infecciosa de la válvula aórtica.

An unusual complication of infective endocarditis (IE) of the aortic valve is called kissing-abscess, caused by the impact of the flow of aortic regurgitation and subsequent contact of vegetations over the anterior mitral valve. The resulting abscesses on the mitral valve can further complicate forming pseud aneurisms. We present the case of a 36-year-old male patient with a 3-month history of fever. A diastolic murmur on the aortic chest wall area was listened and hepatomegaly was also found on the physical examination. A trans-esophageal echocardiography revealed severe aortic insufficiency and perforation of the non-coronary sinus with multiple vegetations, mean size of 4 mm. In addition, the anterior mitral valve had a hypo-echogenic image of 14mm in size consistent with an abscess with Doppler flow in its interior and a pseudo aneurism with multiple sub-valvular vegetations. The extension of IE from the aortic to the mitral valve is associated with high mortality rate needing a prompt diagnosis. [ABSTRACT FROM AUTHOR]
