Catheter ablation of the left ‐sided variant of right top pulmonary vein in a case with persistent left superior vena cava
AbstractA 50-year-old woman underwent catheter ablation for atrial fibrillation. Preoperative computed tomography revealed a left-sided variant of the right top pulmonary vein (PV) and a persistent left superior vena cava. The right top PV was successfully isolated through a wide antral circumferential ablation line simultaneously with the right PVs. (Source: Pacing and Clinical Electrophysiology : PACE)

Epicardial connections and bi ‐atrial tachycardias: From anatomy to clinical practice
AbstractBi-atrial tachycardia (BiAT) is not rare after extensive atrial ablation or cardiac surgery. The complexity of bi-atrial reentrant circuits poses a great challenge for clinical practice. With recent advances in mapping technologies, we are now able to characterize atrial activation in detail. However, given the involvement of both atria and multiple epicardial conductions, endocardial mapping for BiATs is not easy to understand. Knowledge of the atrial myocardial architecture is the foundation for the clinical management of BiATs; as it is required to understand the possible mechanism of the tachycardia and identif...

Preclinical cardiac perforation reduction in leadless pacing: An update to the Micra leadless pacemaker delivery system
ConclusionsThis study, using computer modelling and benchtop experimentation, has indicated that increased surface area and rounding of the updated Micra catheter tip significantly improves preclinical perforation performance. It will be important to evaluate the impact of these catheter design changes with robust registry data. (Source: Pacing and Clinical Electrophysiology : PACE)

Delayed development of a huge chest wall hematoma post pacemaker implantation: A case report
AbstractAn 83-year-old Chinese man presented with a huge left chest wall hematoma and hemorrhagic shock 4 months after permanent pacemaker implantation. Computed Tomography of Angiogram of the left subclavian artery revealed a pseudoaneurysm. He underwent radiologically guided stenting followed by hematoma clearance. It is rare to have delayed formation of pseudoaneurysm at 4 months post pacemaker implantation. Radiologically guided stenting is the preferred treatment, followed by hematoma clearance. It is strongly advised against blind surgery for wound debridement or bleeding detection. Familiarizing with axillary vein a...

Electrophysiological evaluation following development of new and persistent left bundle branch block after transcatheter aortic valve replacement: A single center pilot study
ConclusionNormal HV interval up to 55  ms on modified EP study after TAVR and development of NP-LBBB can be utilized as a threshold for risk stratification to facilitate safe discharge. The optimal upper limit of HV interval threshold remains unclear in determining appropriate candidacy for PPM. (Source: Pacing and Clinical Electrophysiology : PACE)

A retrospective analysis of frailty status on atrial fibrillation catheter ablation outcomes
ConclusionFrailty is associated with poorer outcomes in patients undergoing AF ablation. The eFI may be used in the prognostic evaluation of AF ablation outcomes. Further studies are essential to confirm the findings of this study. (Source: Pacing and Clinical Electrophysiology : PACE)

Inadvertent misplacement of pacemaker lead presented with acute ischemic stroke
AbstractIf a permanent pacemaker lead is misplaced in the left ventricle (LV), the lead may interfere with normal functioning of the heart leading various complications, including heart rhythm problems and blood clots. In our case, the LV lead that passed through the patent foramen ovale and was misplaced into the LV was detected in a 78-year-old patient who presented with embolic stroke. Thrombus regression was achieved with anticoagulation, and then the lead extraction was planned. The lead extraction is a priority in acute cases; but it is not the primary approach in long-term leads that were misplaced into the LV. A pa...
