Electrophysiological Identification of Superior Vena Cava: Novel Insight into Slow Conduction or Conduction Block
AbstractIntroductionIt has not been clarified how to identify the electrophysiological junction between right atrium (RA) and superior vena cava (SVC). The aim of this study was to identify the electrophysiological RA ‐SVC junction according to slow conduction or conduction bock and to examine the electrophysiological SVC isolation procedure.MethodsSeventy ‐three consecutive atrial fibrillation patients who underwent SVC mapping using a CARTO 3 system were enrolled in this study. Slow conduction or conduction block between the RA and SVC was identified by adjusting the lower threshold criteria of the early meets late f...

Acute coronary artery occlusion and ischemia ‐related ventricular tachycardia during catheter ablation in the right ventricular outflow tract
AbstractCoronary artery injury is a rare complication of catheter ablation in the right ventricular outflow tract (RVOT). Furthermore, acute myocardial ischemia usually causes polymorphic ventricular tachycardia (VT) or ventricular fibrillation. We herein describe a case in which catheter ablation for VT originating from the RVOT provoked ischemia ‐related VTs due to acute occlusion of the left anterior descending artery.

Atrio ‐ventricular synchronous pacing with a single chamber leadless pacemaker: Programming and trouble shooting for common clinical scenarios
AbstractMicra leadless pacemaker has progressed from a single chamber pacemaker that can deliver VVIR pacing to a pacing device that can provide atrio ‐ventricular (AV) synchrony via a unique pacing algorithm that relies on identifying mechanical atrial contraction. This novel algorithm has its own limitations and intricacies. In this paper, we review this algorithm, suggest steps for troubleshooting and programming these devices and provide cli nical examples of Micra AV cases that required changes in programming for adequate tracking of atrial activity.

Evaluation of image quality of wideband single ‐shot late gadolinium‐enhancement MRI in patients with a cardiac implantable electronic device
AbstractIntroductionWhile wideband segmented, breath ‐hold late gadolinium‐enhancement (LGE) cardiovascular magnetic resonance (CMR) has been shown to suppress image artifacts associated with cardiac‐implanted electronic devices (CIEDs), it may produce image artifacts in patients with arrhythmia and/or dyspnea. Single‐shot LGE is capable of su ppressing said artifacts. We sought to compare the performance of wideband single‐shot free‐breathing LGE against the standard and wideband‐segmented LGEs in CIED patients.Methods and ResultsWe retrospectively identified all 54 consecutive patients (mean age: 61 &thinsp...
