- Summary
Arrhythmogenic Right Ventricular Dysplasia (ARVD) is an inherited
cardiomyopathy associated with the replacement of myocytes by
fibrous and/or fibroadipose tissue, usually manifesting between the
third and fifth decades of life. In the arrhythmic phase, when it becomes
symptomatic, the patient may experience palpitations, syncope, and
symptomatic ventricular arrhythmias originating in the right ventricle
(RV). The absence of unique and specific diagnostic criteria is a factor
that complicates and delays diagnosis. The main examinations performed
are electrocardiogram (ECG), echocardiogram, and magnetic resonance
imaging (MRI), often showing negative T waves, widening of the QRS
complex with larger S waves, presence of late potentials, incomplete,
complete, or atypical right bundle branch block, combined or isolated, in
addition to the epsilon wave which is characteristic of ARVD. This article
aimed to report the clinical case of a patient with ARVD, from the onset of
signs and symptoms to the outcome of the case. The patient was admitted
with a typical clinical picture of decompensated heart failure and during
complementary exams, the possibility of ARVD was suggested, even with
the nonspecific clinical presentation, later confirming the diagnosis with
cardiac magnetic resonance imaging (MRI) and endomyocardial biopsy.
ARVD is a disease with difficult early diagnosis, often confused with
other pathologies due to presenting signs and symptoms characteristic of
other heart diseases. Adherence to pharmacological treatment alleviates
symptoms and improves quality of life, but in addition, lifestyle changes
and regular follow-up are of paramount importance. - Keywords:
