CTICasesRight Ventricular Insertion Point LGE in Athletes
Imaging findings
Cardiac MRI shows focal late gadolinium enhancement (LGE) localized to the inferior right ventricular insertion point into the interventricular septum, in an asymptomatic high-endurance marathon runner.
Key takeaways
Focal LGE at the RV insertion points (particularly the inferior insertion) is a well-described, benign finding in endurance athletes. It represents mechanical stress and focal myocardial remodeling at the hinge points of the ventricles, rather than true ischemic or pathologic cardiomyopathy.
