Key result
Radiofrequency ablation successfully treated orthodromic reentry utilizing a concealed right septal nodoventricular pathway, resulting in marked improvement in left ventricular function.
Case Report (n=1)
Entrainment mapping is useful for diagnosing rare concealed nodoventricular accessory pathways, which can be successfully treated with radiofrequency ablation to improve ventricular function.

Suggests ablation for rare concealed nodoventricular pathways with LV impairment; leaves open need for larger series before broader adoption.
True nodoventricular (NV) accessory connections, as originally described by Mahaim, are rare entities, with the majority of previously reported cases now recognized as being due to decremental atriofascicular pathways. Here, we present a patient with incessant narrow and wide QRS complex tachycardia occurring in the setting of prior complete heart block. Entrainment mapping proved useful in diagnosing orthodromic reentry utilizing a concealed right septal NV pathway. The patient was successfully treated with radiofrequency ablation, resulting in a marked improvement in left ventricular function.

Quinn et al. (2007) conducted a case report in Complete heart block and tachycardia-induced cardiomyopathy (n=1). Radiofrequency ablation was evaluated on Improvement in left ventricular function. Radiofrequency ablation successfully treated orthodromic reentry utilizing a concealed right septal nodoventricular pathway, resulting in marked improvement in left ventricular function.
