Double-orifice mitral valve (DOMV) is a rare congenital abnormality. Isolated occurrences of this defect are uncommon, and they are usually associated with other congenital heart defects.

Clinical Summary

A 64-year-old woman was found to have a heart murmur suggestive of mitral regurgitation during a routine clinical examination. The patient had a past history of arterial hypertension. She complained of gradually progressive dyspnea for 6 months before admission.

Transesophageal echocardiography showed dilatation of the left and right atria and ventricles, severe mitral regurgitation, moderate tricuspid regurgitation, a large aneurysm of the interatrial septum, and severe pulmonary hypertension. The mitral valve was divided in two by the presence of a middle structure, which created a functional double-orifice valve (Figure 1).

  		Figure 1. Transesophageal echocardiography showed a severe prolapse of the posterior leaflet of the posteromedial orifice and a well-defined bridge with its own subvalvular apparatus that divided the mitral valve into a double-orifice structure. PV, posterior valve; AV, anterior valve; R, rafe (bridge); PO, posterior orifice; AO, anterior orifice.

 
This middle structure was thickened and prolapsed markedly into the atrium during systole, leading to . . . [Full Text of this Article]
