We present 38-years male patient. He has suffered from muscle weakness since 5 years. Arrhythmias appeared at the age of 32. In 37 years he had sick sinus syndrome, transient AV block II degree, paroxysmal atrial fibrillation, atrial flutter, ventricular arrhythmias. At this time, dilated cardiomyopathy was also detected. The evaluation revealed knees and elbows contractures, increased level of creatine kinase. The genetic testing revealed a frame shift deletion c.del619C in the emerin (EMD) gene and c.IVS4-13T> A in the lamin (LMNA) gene, and c.del619C deletion in the heterozygous state in a patient`s mother. Radiofrequency ablation of cavotricuspid isthmus, implantable cardioverter-defibrillator (ICD) implantation were performed. Heart transplantation was performed nine months later, due to severe heart failure and electrical storm. A morphological evaluation revealed sclerosis, atrophy and hypertrophy of cardiomyocytes. He underwent an induction therapy with (basiliximab) methylprednisolone, tacrolimus, mycophenolate after heart transplantation. During 40 months after transplantation, patient`s condition is satisfactory. CONCLUSIONheart failure in Emery-Dreifuss muscular dystrophy can progress quickly unless the previously stable condition. The use of correct regimens of immunosuppression therapy provides good long-term results of the heart transplantation.
