Miocardiopatía arritmogénica del ventrículo derecho: un reporte de caso

Abstract

Introduction: A clinical case of a patient with arrhythmogenic right ventricular cardiomyopathy (ARVC), a rare condition, is described, providing insights into its diagnosis and management. ARVC is commonly associated with sudden death in younger individuals, making it difficult to diagnose and less common in older age groups. This case contributes to clinical knowledge by detailing the clinical manifestations and highlighting the importance of family history in the diagnostic evaluation. Case presentation: A 65-year-old patient consulted for stabbing precordial pain radiating to the epigastrium, palpitations, dizziness, and a family history of sudden death. The electrocardiogram (ECG) revealed T-wave inversion and an incomplete right bundle branch block, while cardiac magnetic resonance imaging showed hypokinesia and late enhancement in the right ventricle, thus meeting the 2010 Task Force criteria for ARVC. The patient was treated with metoprolol to prevent exercise-induced arrhythmias, physical activity was restricted, and follow-up monitoring was scheduled. However, the patient did not attend the follow-up appointment. Conclusion: It is important to consider ARVC as a differential diagnosis in patients presenting with similar clinical profiles, guided by the presence of a family history of sudden death, even when they do not show the typical risk profile.
