Isolated double-orifice mitral valve anomaly on 3-dimensional transesophageal echocardiography

Congenital double mitral orifice with severe mitral regurgitation-associated rheumatoid arthritis: a case report

Background

A double orifice mitral valve (DOMV) represents a rare congenital malformation characterized by two valve orifices with two separate subvalvular apparatus. Double orifice mitral valve is congenital anomaly of the subvalvular mitral valve apparatus consisting of an accessory bridge of fibrous tissue, which partially or completely divides the mitral valve into two orifices.

Case summary

A 30-year young male presented with dyspnoea and palpitation for 4 years, joint pain for 2 years and weakness of right upper limb and lower limb for 6 months. On clinical examination, Boutonniere, Swan neck, and Z-deformity of hand and foot metatarsal bone deformities are noted, on further evaluation, patient was diagnosed as a case of DOMV and was managed conservatively since patient was not willing for surgery.

Discussion

Two-dimensional echocardiography is the best detection method, the parasternal short-axis view being most useful to show DOMV.

Double orifice mitral valve in a patient with bicuspid aortic valve and coarctation of the aorta: A rare presentation

Double orifice mitral valve is a rare condition and may be accompanied by a bicuspid aortic valve (sometimes normal functioning) and coarctation of the aorta. Echocardiography is valuable in detecting the accompanied anomalies. Management depends on the severity of mitral valve function and the severity of associated anomalies.

Successful treatment of double-orifice mitral stenosis with percutaneous balloon mitral commissurotomy

Double-orifice mitral valve (DOMV) is an uncommon congenital anomaly, being present in 0.05% of the general population. The isolated occurrence of this anomaly is very rare and, to our knowledge, no data are currently available on the incidence of an isolated DOMV. A DOMV is characterized by a mitral valve with a single fibrous annulus with 2 orifices opening into the left ventricle (LV). Subvalvular structures, especially the tensor apparatus, invariably show various degrees of abnormality. It can substantially obstruct mitral valve inflow or cause mitral valve incompetence. We present a rare case of nineteen-year-old male who underwent percutaneous mitral balloon commissurotomy in stenotic DOMV.
