[Arrhythmogenic right-ventricular cardiomyopathy: different manifestations as precursors of sudden death which might be prevented].
Two men aged 47 and 56 and one woman aged 21 presented at our cardiology department with presyncope, heart failure and exercise induced palpitations, respectively. Using the criteria of McKenna et al., a diagnosis of arrhythmogenic right-ventricular cardiomyopathy (ARVC) was made. Following implantation of a defibrillator, one of the men experienced seven appropriate interventions within six months and also developed psychological problems. The other man was problem-free and the woman recovered reasonably well, having only one appropriate intervention from the defibrillator one year after implantation. Indications of ARVC were also found in her mother but not in any other family members. Because ARVC manifests itself in various different ways it is difficult to diagnose. It is important to consider ARVC in patients with exercise-induced palpitations, presyncope, and unexplained cardiomyopathies or arrhythmias, especially if there is a family history of unexpected deaths. ARVC is a potentially life-threatening disease, that may require implantation of a cardioverter defibrillator. Furthermore, since genetics play an important role and ARVC can be asymptomatic, evaluation of close relatives for preclinical symptoms is important.
