Emery-Dreifuss muscular dystrophy (EDMD) is an X-linked muscular dystrophy in which cardiac involvement can be serious. The disease progresses rapidly and the prognosis is strongly associated with cardiac involvement. We present the case of a 49-year-old man who was admitted with shortness of breath. Echocardiography revealed a huge right atrium and severe tricuspid regurgitation caused by annular dilatation and destruction of leaflets and chordae by pacemaker leads. Tricuspid valve replacement, right atrial plication and implantation of epicardial pacemaker leads were performed. The patient is in a good condition seven years after surgery. Cardiac transplantation is the desired therapy for valvular disease in EDMD cardiomyopathy, but this case indicates that valve replacement is also acceptable if performed with the appropriate timing.

Emery-Dreifuss muscular dystrophy is an early-onset, slowly progressive myopathy characterized by the development of multiple contractures, muscle weakness and cardiac dysfunction. We present here the case of a 65-year-old male patient with a 20 year history of slowly progressive camptocormia, bradycardia and shortness of breath. Examination showed severe spine extensor and neck flexor muscle weakness with slight upper limb proximal weakness. Cardiologic assessment revealed slow atrial fibrillation. Whole body MRI demonstrated adipose substitution of the paravertebral, limb girdle and peroneal muscles as well as the tongue. Emerin immunohistochemistry on patient muscle biopsy revealed the absence of nuclear envelope labeling confirmed by Western Blot. Genetic analysis showed a hemizygous duplication of 5 bases in exon 6 of the EMD, emerin, gene on the X chromosome. This is an unusual presentation of X-linked Emery-Dreifuss muscular dystrophy with adult onset, predominant axial muscles involvement and minimal joint contractures. Diagnosis was prompted by the analysis of emerin on muscle biopsy.
