Persistence of an iatrogenic atrial septal defect after a second-generation cryoballoon ablation of atrial fibrillation

Persistent iatrogenic atrial septal defects (iASDs) can be observed after intervention requiring a left atria (LA) access, including pulmonary vein isolation (PVI) of atrial fibrillation (AF). We investigated ...

Optimal slow pathway ablation site for slow-fast atrioventricular nodal reentrant tachycardia with 2:1 atrioventricular conduction

The exact circuit responsible for the atrioventricular (AV) nodal reentrant tachycardia (AVNRT) is still unknown. We evaluated the optimal slow pathway ablation area in patients with and without 2:1 AV conduct...

Shift in the earliest retrograde atrial activation site during the fast–slow form of atrioventricular nodal reentrant tachycardia after the radiofrequency modification of the atrioventricular node: is the atrium a necessary link?

Whether or not the perinodal atrium forms an upper link in the tachycardia circuit of the atypical form of AV nodal reentrant tachycardia (AVNRT) is controversial. We report a case with the fast–slow form of A...

All–to–All Personalized Communication Algorithms in Chordal Ring Networks

Chordal ring networks are ring structured and they become unreliable when nodes or arcs in the ring break down. Such a shortcoming can be circumvented by adding duplicate rings. Though this inherent topology o...
