Key result
Continuous RVP in young AV block patients is linked to adverse outcomes driven by ventricular dyssynchrony.
Why the study?
Continuous RV apical pacing for permanent CAVB is associated with unfavorable outcomes from ventricular dyssynchrony, prompting a summary of current literature and exploration of future treatment perspectives in pediatric and young adult patients.
This review highlights the etiology of CAVB in pediatric and young adult patients and discusses the limitations of traditional RV apical pacing, exploring future device therapy perspectives.
May warrant alternative pacing sites in pediatric CAVB; leaves open optimal strategies pending prospective trials.
Complete atrioventricular block (CAVB) is a total dissociation between the atrial and ventricular activity, in the absence of atrioventricular conduction. Several diseases may result in CAVB in the pediatric and young-adult population. Permanent right ventricular (RV) pacing is required in permanent CAVB, when the cause is neither transient nor reversible. Continuous RV apical pacing has been associated with unfavorable outcomes in several studies due to the associated ventricular dyssynchrony. This study aims to summarize the current literature regarding CAVB in the pediatric and young adult population and to explore future treatment perspectives.

Cioffi et al. (2021) conducted a review in Complete atrioventricular block (CAVB). Permanent right ventricular pacing was evaluated. Continuous right ventricular apical pacing for complete atrioventricular block in pediatric and young adult populations is associated with unfavorable outcomes due to ventricular dyssynchrony.
