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

UNLABELLED INTRODUCTION Annular subvalvular pseudoaneurysm is a rare example of left ventricle aneurysm described predominantly in young African people. These aneurysms are divided into two different types, namely, submitral or subaortic, with subaortic being the less frequent kind. The subaortic type is most often localized in the mitral-aortic intervalvular fibrosa. To the best of our know...

Infection of the mitral-aortic intervalvular fibrosa occurs most commonly in association with infective endocarditis of the aortic valve. Infection of the aortic valve results in a regurgitant jet that presumably strikes this subaortic interannular zone of fibrous tissue and produces a secondary site of infection. Infection of this interannular zone then leads to the formation of subaortic absc...

Mitral-aortic intervalvular fibrosa (MAIVF) pseudoaneurysm is detected by echocardiography as a pulsatile structure at the mitral-aortic junction near the left ventricular outflow tract. Depending upon the severity of fistulization into the left atrium, acute mitral deficiency like clinical conditions may develop (1). Aortic valve endocarditis is the most commonly known etiological condition (2...

BACKGROUND The entity pseudoaneurysm arising from the mitral aortic intervalvular fibrosa (P-MAIVF) is a rare cardiac finding caused by multiple factors. This entity is usually diagnosed with echocardiography and confirmed with cardiac computed tomography (CT). CASE REPORT We presented a case of congenital P-MAIVF communicating with the left atrium (LA) and an aberrant right subclavian artery...

We present the apparently unique M-mode and two-dimensional echocardiographic features of a surgically confirmed pseudoaneurysm of the left ventricular outflow tract, which probably developed as a result of perforation of the mitral-aortic intervalvular fibrosa. Echocardiographic studies revealed an aneurysmal sac situated between the aortic root and the left atrium. The aneurysm expanded in sy...
