T he incidence of prosthetic valve endocarditis ranges from 2% to 4%, with an average of 2.4%.x Endocarditis occurring ^60 days after surgery is described as early prosthetic valve endocarditis and is primarily related to bacteremia associated with indwelling vascular catheters or perioperative infection; offending organisms are most commonly Staphylococcus aureus, S. epidermidis, and diptheroids. Endocarditis occurring >60 days after valve replacement is described as late prosthetic valve endocarditis and is related to bacteremia associated with minor surgery, skin infections, dental procedures, or a variety of gastrointestinal and genitourinary tract procedures; offending organisms are most commonly Staphylococcus spp. and Streptococcus spp.1

“…[4][5][6][7][8][9][10][11][12][13] First, the species of viridans streptococci in this case was S. mitis, which has not been reported as a cause of bioprosthetic aortic valve late PVE. Another unusual feature was the paravalvular abscess, which is less common in viridans streptococcal late PVE than in other invasive cardiac pathogens.…”

“…6 Some investigators believe that many cases of PVE that occur during the first year after surgery are acquired at the time of implantation and further recommend that the time limit for early disease be extended to 6 months or even 1 year from implantation. 7 The prognosis in PVE is clearly worse than in native valve. Late PVE has a mortality rate of 19% to 50% which is slightly better than that of early PVE which carries a mortality rate of 41% to 80%.…”

MAIVF is the junction between the left half of the non-coronary cusp and the adjacent third of the left coronary cusp of the aortic valve and the anterior mitral leaflet.…”

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (MAIVF) is one of the rare complications of infective endocarditis. Echocardiography plays an important role in the diagnosis of this condition. Transesophageal echocardiography (TEE) is generally superior to the transthoracic approach in the evaluation of the complications resulting from infective endocarditis. In this report, we discuss a case of infective endocarditis complicated by the development of a pseudoaneurysm of the MAIVF. The anatomic relationship of structures contiguous to the MAIVF and the salient echocardiographic findings of this clinical condition are presented. At surgery the diagnosis was confirmed and appropriate treatment instituted. The postoperative course was uncomplicated. INTRODUCTIONTransesophageal echocardiography (TEE) is known to be superior to transthoracic echocardiography (TTE) in the visualization of valvular vegetations, abscesses and other complications in patients with infective endocarditis. 1 One such complication is the development of false aneurysms of the mitral-aortic intervalvular fibrosis. 2-3 These false aneurysms are prone to rupture, embolize or even cause further destruction of the aortic or mitral valve apparatus. [4][5] It is, therefore, important to recognize this complication early, and to institute appropriate surgical treatment in a timely fashion in order to decrease the morbidity and mortality. This case report describes a patient with a protracted course of infective endocarditis who was diagnosed with a false aneurysm of the mitral-aortic intervalvular fibrosa (MAIVF). Since TTE was unable to provide adequate information, TEE was performed and proved extremely valuable in the proper diagnosis and treatment of our patient. This case report was approved by the Institutional Review Board.
