Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) in a Special Operations Soldier: A Case Report
Osborne K, Wenthe A, Mahowald M, Bridwell R 24(2). 82-84 (Case Reports)
Special Operations Servicemembers presenting with palpitations, pre-syncope, or exertional syncope during rigorous physical training are often experiencing a benign condition; however, life-threatening etiologies should be considered. We describe a 43-year-old Special Operator who presented to his medics during selection physical assessment testing with palpitations and lightheadedness, with a subsequent workup revealing arrhythmogenic right ventricular cardiomyopathy (ARVC). His initial electrocardiogram was unremarkable without characteristic ARVC changes. Outpatient evaluation with ambulatory cardiac monitoring recorded numerous episodes of non-sustained ventricular tachycardia. Transthoracic echocardiography demonstrated findings concerning for ARVC, with subsequent cardiac MRI confirming the diagnosis via the 2020 Padua criteria. Management includes activity modification, class III anti-arrhythmic medications, and possible placement of an implantable cardioverter defibrillator to prevent sudden cardiac death. This case demonstrates the importance of maintaining high clinical suspicion for rare diagnoses that present with exertional palpitations, such as arrhythmogenic right ventricular cardiomyopathy, in even our fittest Special Operators.
