Double-orifice mitral valve associated with atrioventricular canal defects

Double-orifice mitral valve associated with atrioventricular canal defects

A 4 year-old male presented with effort dyspnea, and was diagnosed as atrioventricular canal defects. This finding was confirmed by open heart surgery, and a congenital double orifice mitral valve was discovered. The septal defect was closed but the double orifice mitral valve was respected because of the absence of hemodynamic disturbance. We report this case with review of literature.

Surgically created double-orifice left atrioventricular valve: a valve-sparing repair in selected atrioventricular septal defects.

OBJECTIVES Some features of the left atrioventricular valve (large mural leaflet, dystrophic tissue) represent a challenge for repair of atrioventricular septal defects without postoperative regurgitation. A retrospective study was conducted to evaluate the results of surgically creating a double-orifice left atrioventricular valve in such circumstances. Clinical results were analyzed according...

Double-Orifice Mitral Valve with Leaflet Perforation

Double-orifice mitral valve - echocardiographic findings.

BACKGROUND Double-orifice mitral valve (DOMV) is a rare congenital malformation characterised by the presence of two orifices in the left atrio-ventricular valve area, each having an independent chordal attachment to the papillary muscle. AIM To establish the echocardiographic features and incidence of DOMV in patients undergoing an echo study in a tertiary referral centre. METHODS We carri...

Double 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.
