Background:
Prompt recognition of arrhythmogenic conditions in recreational and competitive athletes is essential for clinical management and for providing appropriate exercise recommendations.
Case Summary:
We report the case of a 67-year-old athletic individual with a high burden of ventricular arrhythmias and a phenotype within the dilated/nondilated left ventricular cardiomyopathy spectrum. Genetic testing identified a likely causative variant in the Filamin C (FLNC) gene. An integrative evaluation incorporating advanced cardiac imaging, genetic analysis, and invasive electrophysiology was undertaken to optimize risk stratification and customize exercise counseling.
Discussion:
In arrhythmogenic cardiomyopathy with confirmed or suspected genetic etiology, a multimodal evaluation is essential for accurate patient phenotyping. The impact of exercise on disease expression in specific gene variants associated with predominantly left-sided involvement remains insufficiently understood and requires further research and shared decision-making.
Take-Home Message:
A comprehensive multidisciplinary evaluation is key for diagnosis, risk stratification, and management of athletes with ventricular arrhythmias.
