Recognizing a "Hot Phase" of An Arrhythmogenic Left Ventricular Cardiomyopathy: A Case Report

J Saudi Heart Assoc. 2023 Oct 16;35(3):232-234. doi: 10.37616/2212-5043.1348. eCollection 2023.


A 35-year-old male, with a medical history of acute myocarditis, presented with palpitations. Further investigation revealed non-sustained ventricular tachycardia and a slightly reduced left ventricular systolic function. Cardiac magnetic resonance showed extended late gadolinium enhancement of the left ventricle and fat infiltration. Genetic testing was positive for a pathogenic desmoplakin mutation, fulfilling the criteria of arrhythmogenic left ventricular cardiomyopathy. In conclusion, the authors described a case of a mimicked acute myocarditis at a young age in a patient with an arrhythmogenic left ventricular cardiomyopathy. Therefore, the genetic study is essential for both diagnosis and management.
