“…The natural history of mitral-aortic intervalvular fibrosa is unclear. Most patients undergo early surgical correction to prevent rupture, however, some patients have survived without surgery with follow-up periods varying from 10 to 63 months (9). In the present case, the pseudoaneurysm was only detected by transesophageal echocardiography and surgery was not performed.…”

Infective Endocarditis Presenting as Acute Renal Failure and Unusual Complications

Infective endocarditis can be a diagnostic challenge. Few cases have so far reported infective endocarditis presenting as renal failure. Pseudoaneurysms of the mitral-aortic intervalvular fibrosa and splenic abscess are rare complications of infective endocarditis. We herein report a case of an 80-year-old man admitted due to anorexia, malaise, edema of the legs and renal failure. A progressive degradation of the patient's renal function was documented and hemodialysis was started. Blood cultures revealed the presence of Enterococcus faecalis, and the patient was treated with ampicillin and gentamicin. The transesophageal echocardiogram findings showed pseudoaneurysms of the mitral-aortic intervalvular fibrosa and in the aortic root wall. Due to abdominal pain, an abdominal CT scan was performed and showed a cystic lesion compatible with splenic abscess. The patient received 6 weeks of antibiotic treatment. There was progressive clinical improvement and regression of the splenic abscess, but no recovery of the renal function. This report illustrates an unusual clinical presentation of infective endocarditis with unusual complications that were successfully treated with antibiotics.

“…Pseudoaneurysm of the mitral-aortic intervalvular fibrosa is a rare but potentially fatal complication of infective endocarditis and aortic valve surgery (9). Infection can result in abscess formation and pseudoaneurysm in the mitral-aortic intervalvular fibrosa area.…”

“…[123] MAIVF or aorto-mitral valvular curtain is the tissue located in the fibrous connection between the aortic valve cusp and anterior leaflet of mitral valve. [45] As perforation of this tissue during surgery or trauma is known to cause the aneurysm, an inherent deficiency at this site may explain the congenital aneurysm formation.…”

Congenital pseudoaneurysm of mitral-aortic intervalvular fibrosa masquerading as left atrial mass in fetal life

A 28-week-old fetus was detected to have a single left atrial mass in prenatal ultrasound. Postnatal echocardiography showed an aneurysm between the anterior mitral leaflet and aortic valve, to the left of atrioventricular junction and communicating with the left ventricle through a narrow mouth. It probably originated from the mitral-aortic intervalvular fibrous tissue and an inherent weakness at this site might be the cause. Reported cases of pseudoaneurysm of mitral-aortic intervalvular fibrosa and subvalvular ventricular aneurysms seen following infective endocarditis, surgery, or trauma seem to have a similar anatomical background. This case explains the possibility of congenital aneurysm in this location which needs to be considered a differential diagnosis in similar cases.

“…It commonly occurs in patients with infective endocarditis, aortic valve surgery, or chest trauma [1,5,6] . Few cases have been attributed to congenital abnormality, including bicuspid aortic valve, ventricular septal defect, atrial septal defect, or patent ductus arteriosus [4,5] . The pathogenesis of P-MAIVF still remains largely undefined, but it has been suggested that it may develop from either direct extension of endocarditis of aortic valve or from an "infected" aortic regurgitation jet which strikes the subvalvular structures [9] .…”
