Brugada syndrome in a young patient with type 1 myotonic dystrophy requiring an implantable cardioverter defibrillator for primary prevention: a case report
BACKGROUND : Cardiac electrical disturbances represent the most frequent cardiac manifestations of myotonic dystrophy Type 1 (MD1). Limited data suggest that the prevalence of Brugada syndrome in MD1 may be increased compared to the general population. CASE SUMMARY : We report a case of a 22-year-ol...

Sumario: | BACKGROUND : Cardiac electrical disturbances represent the most frequent cardiac manifestations of myotonic dystrophy Type 1 (MD1). Limited data suggest that the prevalence of Brugada syndrome in MD1 may be increased compared to the general population. CASE SUMMARY : We report a case of a 22-year-old asymptomatic man with repolarization abnormalities in leads V1–V3 suggestive of Type III Brugada pattern. The patient had a family history of MD and incidents of sudden death in relatives. Drug-induced Brugada Type 1 syndrome was revealed after procainamide challenge. A ventricular stimulation study was positive since a polymorphic ventricular tachycardia was induced after two extrastimuli. The patient underwent implantation of a single chamber cardiac defibrillator (ICD). Eight months after the procedure he suffered an appropriate ICD shock due to rapid polymorphic ventricular tachycardia. DISCUSSION : Brugada syndrome is linked with MD1. Potential life-threatening arrhythmias may develop in the adult life of MD1 patients. Electrocardiographic surveillance and tailored invasive treatment with ICDs can prevent sudden cardiac death in this setting. |
