This paper reports the experience of successful cryoablation of fast atrioventricular nodal pathway in a patient with recurrent atrioventricular nodal reentrant tachycardia after previous unsuccessful attempts of slow pathway ablation. Slow formation of a permanent lesion by cryothermal energy application allowed precise modulation of atrioventricular nodal conduction until the endpoints of complete fast pathway ablation were met with long-term cure of the arrhythmia.

We encountered a single case in which a transition between orthodromic reciprocating tachycardia with a concealed nodoventricular pathway and atrioventricular nodal reentrant tachycardia with a bystander nodoventricular pathway was observed.

Background: Junctional rhythm (JR) frequently occurs during radiofrequency (RF) ablation procedures targeting the slow pathway (SP) for atrioventricular nodal re-entrant tachycardia (AVNRT), signaling successful ablation. Two types of JR have been noticed: typical JR as His activation preceding atrial activation, and atypical JR as atrial activation preceding the His activation. Nevertheless, the origin and characteristics of JR remain incompletely defined.

Background: Left bundle branch (LBB) pacing (LBBP) has gained rapid adoption. Evidence for direct LBB capture has varied from 30%-95% depending on the criteria.
Objective: The purpose of this study was to assess the feasibility and efficacy of intraprocedural transthoracic echocardiographic guidance to achieve LBB capture.
