Double orifice mitral valve visualized on echocardiography and MRI
نویسندگان
چکیده
A 21-year-old, previously healthy, female presented with complaints of palpitations. The physical examination, ECG and a 24-hour Holter investigation were unremarkable. A transthoracic echocardiogram demonstrated a double orifice mitral valve (DOMV) (Fig. 1). Cardiac magnetic resonance imaging was performed in order to exclude other congenital heart problems (Fig. 2). There was no evidence of mitral valve stenosis, regurgitation or other cardiac morphological abnormalities. First described in 1876 by Greenfield [1], DOMV is an uncommon anomaly which, as its name indicates, has a single mitral annulus and opens into the left ventricle through two orifices. Depending on the relative size and location of the two orifices, DOMV can be classified into an eccentric type (found in 85% of cases) and a central or bridge type (as in our patient’s case) [2]. Mitral stenosis or regurgitation and other congenital malformations such as atrioventricular or ventricular septal defects may be associated with DOMV [3, 4].

Double orifice mitral valve (DOMV) is an uncommon anomaly that was first described by Greenfield. Since then more than 200 cases have been reported. In this anomaly, mitral valve has a single fibrous annulus which opens with two openings into the left ventricle. We report a case of DOMV accompanied with severe stenosis in a 22-year old female who had complaints of moderate dyspnea. In transth...
متن کاملDouble orifice mitral valve; a coincidental finding.
A double orifice mitral valve (DOMV) represents a rare congenital malformation characterised by two valve orifices with two separate subvalvular apparatus. This case demonstrates the necessity of careful imaging of the mitral valve apparatus, not only in patients with atrioventricular septal defects, but also in patients with congenital left obstructive heart disease.
متن کاملTwo-dimensional echocardiography in double orifice mitral valve.
In a patient with endocarditis and significant aortic insufficiency, two-dimensional echocardiography revealed an abnormal mitral valve configuration with division of the valve into two separate orifices. At autopsy, a double orifice mitral valve with two sets of valve leaflets was observed. Appreciation of this echocardiographic abnormality is important because double orifice mitral valve is a...

Double orifice mitral valve (DOMV) is an uncommon anomaly characterized by a mitral valve with a single fibrous annulus with two orifices opening into the left ventricle. Here we present a rare case of DOMV with ventricular septal defect (VSD) which was detected by 2-D echocardiography.
