Key Points
EXERCISE-INDUCED CARDIAC REMODELING (EICR)
- Clinical imaging specialists performing and/or interpreting imaging studies in CA should possess a basic knowledge of fundamental exercise physiology and EICR.
- The magnitude (i.e., absolute wall thickness and chamber dimensions/volumes) and geometry (eccentric vs. concentric) of LV adaptation in CA is defined by the complex interplay between numerous factors, including sport type, sex, ethnicity, and duration of prior exercise exposure.
- When due to EICR, RV dilation, a common adaptation in CA engaging in endurance sports, should be accompanied by LV eccentric remodeling/hypertrophy and biatrial dilation.
- Mild aortic sinus or ascending aortic dilation may occur in young CA but absolute aortic measurements of ≥40 mm (men) and ≥34 mm (women) are uncommon. A finding of aortic sinus or ascending aortic dimensions in excess of these sex-specific cut-points should prompt clinical consideration of aortic pathology and subsequent imaging with either gated CTA or CMR.
