“…The electrophysiological characteristics of focal AT near the aortic cusps have been previously reported. 12) First, the P-wave duration is shorter than that during the sinus rhythm in the usual interatrial septal non-PV triggers like septal PACs. In the present study, we have reported the same observation.…”

“…Several studies have suggested that para-Hisian ATs can be successfully ablated in the NCC in the aorta. 12) 18) Therefore, further investigation is required on the characteristics of AT that is successfully ablated in the NCC and its role as a non-PV trigger.…”

“… 6) In contrast, in those types of AT cases, catheter ablation within the base of the NCC represented a safe and effective procedure outcome in the previous reports. In the recent study, Yamabe et al 12) reported that ablation of AT arising near the atrioventricular node from NCC is effective and safe. Ouyang et al 6) reported successful catheter ablation in the NCC for focal AT near the His-bundle region without AV block in 9 patients.…”

Prevalence and Characteristics of Atrial Tachycardia From Noncoronary Aortic Cusp During Atrial Fibrillation Catheter Ablation

et al. 2022

Author's summary The prevalence of the uncommon atrial tachycardia (AT) originating from the non-coronary cusp (NCC) in patients undergoing atrial fibrillation (AF) ablation were overall 0.08% (0.07% in initial AF ablation cases, and 0.15% in redo cases). The characteristics of NCC ATs uncovered during AF ablation presented shorter tachycardia cycle length and increased P-wave duration compared to that of de novo NCC AT without AF. The AF recurrence rate after pulmonary vein isolation and NCC AT ablation was low without significant procedure related complication such as atrioventricular conduction block.

“…It is noteworthy that this distribution of SP tissue resembles that of the origin of verapamil- (or adenosine-) sensitive atrial tachycardia. Adenosine-sensitive atrial tachycardia originating from the vicinity of the AV node is a distinctive form of reentrant atrial tachycardia which can be ablated on the right side of the perihisian region [ 66 , 67 , 68 , 69 ], or from the non-coronary sinus of Valsalva [ 47 , 68 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 ]. These sites are also preferred to ablate superior SP [ 12 , 33 ].…”

Our understanding of the variants of slow pathway (SP) and associated atypical atrioventricular (AV) nodal reentrant tachycardia (NRT) is still growing. We have identified variants extending outside Koch's triangle along the tricuspid annulus, including superior, superoanterior and inferolateral right atrial SP and associated atypical, fast-slow AVNRT. We review the history of each variant, their electrophysiological characteristics and related atypical AVNRT, and their treatment by catheter ablation. We focused our efforts on organizing the published information, as well as some unpublished, reliable data, and show the pitfalls of electrophysiological observations, along with keys to the diagnosis of atypical AVNRT. The superior-type of fast-slow AVNRT mimics adenosine-sensitive atrial tachycardia originating near the AV node and can be successfully treated by ablation of a superior SP form the right side of the perihisian region or from the non-coronary sinus of Valsalva. Fast-slow AVNRT using a superoanterior or inferolateral right atrial SP also mimics atrial tachycardia originating from the tricuspid annulus. We summarize the similarities among these variants of SP, and the origin of the atrial tachycardias, including their anatomical distributions and electrophysiological and pharmacological characteristics. Moreover, based on recent basic research reporting the presence of node-like AV ring tissue encircling the annuli in adult hearts, we propose the term "AV ring tachycardia" to designate the tachycardias that share the AV ring tissue as a common arrhythmogenic substrate. This review should help the readers recognize rare types of SP variants and associated AVNRT, and diagnose and cure these complex tachycardias. We hope, with this proposal of a unified tachycardia designation, to open a new chapter in clinical electrophysiology.
