Evaluation of Congenital Mitral-aortic Intervalvular Fibrosa Aneurysm: Role of Multidetector Computed Tomography in Congenital Heart Disease
نویسندگان
چکیده
Mitral-aortic intervalvular fibrosa aneurysm is a rare disease entity whose aetiology remains uncertain. Most of the cases reported are believed to be a sequela of infective endocarditis. We present a case of congenital mitralaortic intervalvular fibrosa aneurysm, representing the first patient to be diagnosed at birth in the literature. This report illustrates the imaging features of mitral-aortic intervalvular fibrosa aneurysm and the role of multidetector computed tomography in the diagnostic process.

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...

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...

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...

BACKGROUND Secondary involvement of the mitral-aortic intervalvular fibrosa and the anterior mitral leaflet (subaortic structures) can occur in patients with aortic valve endocarditis. The secondary involvement of these structures occurs as a result of direct extension of the infection from the aortic valve or as a result of an infected aortic regurgitant jet striking the ventricular surfaces o...

Sixteen-slice multidetector CT findings of a pulsatile pseudoaneurysm of the mitral-aortic intervalvular fibrosa, in a woman following aortic valve replacement, are presented. Multidetector CT depicted the pseudoaneurysm and enabled dynamic evaluation of its lumen through the cardiac cycle, documenting expansion during systole and almost complete collapse during diastole. This case illustrates ...
