[Clinical case of the cardiovascular system involvement in a patient with Charcot-Marie-Tooth disease].

Abstract

Hereditary motor and sensory type 1A neuropathy (known as Charcot-Marie-Tooth disease) is a disease of peripheral nerves characterized by symptoms of progressive polyneuropathy with preferential damage of distal extremity muscles. Damage to the cardiovascular system is extremely rare and heterogenous in this pathology. This disease is not included in the list of indications for interventional antiarrhythmic aid. We could not find in available literature a clinical description of the development of sinus node dysfunction associated with this pathology. The present clinical report presents a case of detection and successful treatment of a damage to the cardiovascular system that manifested itself as sinus node dysfunction/sick sinus syndrome in the tachy-brady variant. A combination treatment approach using radiofrequency catheter ablation, implantation of a permanent pacemaker, and antiarrhythmic therapy associated with drug and non-drug treatment of motor sensory neuropathy resulted in recovery and long-term maintenance of sinus rhythm as well as in beneficial changes in the patient's neurological status.
