High-grade atrioventricular block in young adults can indicate left ventricular noncompaction despite preserved ejection fraction, requiring evaluation with cardiac magnetic resonance.
Unexplained high-grade AV block in young adults warrants advanced imaging like CMR to rule out cardiomyopathies such as left ventricular noncompaction.

Unexplained high-grade atrioventricular block in a young adult should prompt advanced structural evaluation-including cardiac magnetic resonance-to exclude left ventricular noncompaction and other cardiomyopathies. Preserved ejection fraction and absent late gadolinium enhancement can coexist with clinically relevant conduction disease in left ventricular noncompaction. Implantable loop recorder-guided surveillance enables individualized timing of device therapy and complements genetic evaluation and cascade family screening.
