Clinical image
Doubling the mitral valve is a rare congenital heart defect. It is Characterized by the presence of two smaller mitral apparatus, Generally attachment system, is located in the anterior mitral cusp, separated by a fibrous tissue.1 The explanation of the change in the embryological development is accepted by an abnormality in the development between the ventral or dorsal medial tubers pad with side.2,3
Usually they associated with aortic aneurysm, bicuspid aortic valve, aortic coarctation, subaortic stenosis, patent ductus arteriosus, abnormal interatrial and interventricular septum. They may evolve failure and / or mitral stenosis. (Figures 1–4)

Echocardiography is essential for the diagnosis, treatment and follow-up.4–5 We present a newborn preterm, low birth weight, the doppler echocardiogram applying for breath. echodopplercardiogram is performed evidencing patent foramen ovale with shunt from left to right, moderate muscle septal shunt left to nonsignificant right, double mitral apparatus, permeable, no records diastolic gradient and mild impairment of both, patent ductus arteriosus, big, not restrictive and overactive.
