Abstract:
Objective:To review the imaging characteristics and evaluate the diagnostic value of Doppler echocardiography for congenital pseudoaneurysm of the mitral-aortic intervalvular fibrosa (PMAIVF).Methods:Between June 2008 and January 2020, 4 patients with PMAIVF were diagnosed by CTA, MRI and operative findings in Shanghai Children′s Medical Center and Children′s Hospital of Soochow University. The echocardiographic characteristics were analyzed retrospectively in these children.Results:PMAIVF was characterized by a pulsatile echo-free sac that expanded in systole and collapsed in diastole with to-and-fro blood flow on color and pulsed-wave Doppler echocardiography between the mitral leaflet and the aortic annulus. Three cases were diagnosed correctly, and 1 case was misdiagnosed as left atrial mass.Conclusions:PMAIVF can be diagnosed accurately by Doppler echocardiography, but it is prone to be misdiagnosed and must be distinguished from aortic root abscess, atrial mass and coronary artery fistula.
