Late gadolinium enhancement (LGE) magnetic resonance imaging (MRI) has been shown to reliably locate RFA lesions with microvascular obstruction (MVO) as a broadly accepted signature. However, MVO volume depends on the time elapsed after gadolinium contrast injection. Native T1w MRI has recently been shown to accurately characterize RFA lesions in preclinical models.

Primum non nocere constitutes a central pillar of medicine, retaining its relevance across nearly all domains of clinical practice. When faced with a catastrophic event in a young athlete previously considered in peak health, who has been resuscitated on the field and is found to have a markedly hypertrophic left ventricle, it is natural that our instincts as medical professionals orient toward harm prevention. This invariably leads to a strong imperative to remove the apparent precipitating factor – namely, sports and exercise.
