A duplicate mitral valve is especially uncommon in patients with double-orifice mitral valve (DOMV).1Go We herein report a case demonstrating an isolated duplicate mitral valve with a torn chordae in which mitral valvuloplasty was undertaken successfully.

Clinical Summary

A 46-year-old male patient with severe mitral regurgitation (MR) was admitted to our department. He had had dyspnea for 5 months, which had gradually worsened over time. A regurgitant systolic murmur, grade 4/6, was audible at the apex. Left ventricular angiography showed severe grade 4/4 MR. An echocardiogram indicated a diagnosis of torn chordae at the posteromedial scallop of the posterior mitral leaflet.

A preoperative Doppler echocardiogram showed the area of the two mitral orifices to measure 5.5 cm2 in size on the posteromedial side and 2.4 cm2 in size on the anterolateral side (Figure 1). Severe MR caused by torn chordae was found only from the lateral mitral valve. The tissue separating the two orifices looked stiff, in contrast to the fibrous string connecting the two leaflets.
