Key result
Temporary permanent pacemakers allowed safe cardiovascular magnetic resonance imaging without adverse events in 17 patients with advanced atrioventricular block, yielding a specific diagnosis in 8 patients.
nlike conduction disease in elderly patients, advanced atrioventricular block in young and middleaged patients is predominantly attributable to causes other than degenerative conduction disease and coronary artery disease. 1 Frequent causes of advanced atrioventricular block in young people include cardiac sarcoidosis, 2-4 giant cell myocarditis, 2 genetic cardiomyopathies 5 caused by mutations in LMNA, 6 SCN5A, 7 and EMD, 8 and Lyme carditis in places where Lyme disease is endemic.

Wald et al. (2022) conducted an editorial in Advanced atrioventricular block (n=17). Temporary permanent pacemakers (TPPM) to allow CMR was evaluated on CMR-related adverse events and diagnostic yield. Temporary permanent pacemakers allowed safe cardiovascular magnetic resonance imaging without adverse events in 17 patients with advanced atrioventricular block, yielding a specific diagnosis in 8 patients.
