Benefits of catheter ablation of typical cavotricuspid isthmus-dependent atrial flutter using half-normal saline
Conclusions RFA of AFL using HNS is an effective and safe procedure. In patients with unfavorable anatomy who required a greater number of applications, the radiofrequency time was significantly shorter using HNS.

Cognitive outcomes post-catheter ablation for atrial fibrillation: a systematic review and meta-analysis
Conclusion: AF catheter ablation may reduce the incidence of dementia and improve cognitive function. A large-scale randomized control trial is warranted before recommendations can be made regarding AF ablation and cognitive outcomes. Abstract Figure. (Source: Europace)

A minimally fluoroscopic approach in AVNRT ablation reduces radiation exposure and number of RF applications without compromising safety, effectiveness and procedural time
ConclusionAVNRT catheter ablation using a minimally fluoroscopic approach with 3D electro-anatomical mapping systems reduces radiation exposure without compromising safety, effectiveness and procedural time. EAMS use is associated with a reduction in the number of RF applications suggesting a higher precision and stability of ablation catheters during RF application. (Source: Europace)

A novel non-invasive electrocardiographic imaging technique facilitates the preprocedural diagnostic workup of patients with infrequent ventricular arrhythmias
ConclusionsNon-invasive ECGI pace-map is a unique tool that can identify the origin of infrequent VAs in an outpatient clinical setting in order to screen out patients not feasible for CA. Low burden PVCs maybe attempted to be ablated when the source is clearly associated of certain anatomical structures. (Source: Europace)

Noninvasive unipolar electrogram T-wave upslope is an accurate marker of local refractoriness in explanted hearts with drug-induced repolarization dispersion
ConclusionThe moment of steepest upslope of the T-wave in a noninvasively reconstructed UEG accurately reflects end of local refractoriness in intact hearts, in case of pronounced RT dispersion. Under these circumstances, when local RT is defined by moment of re-excitability (allowing to link it to conduction block and re-entry), ECGI T-wave upslope can be taken as a truthful marker for local RT.

Home fitting of electrocardiogram (ECG) ambulatory monitors during covid-19
ConclusionsThis project enabled vital cardiac diagnostics whilst maintaining social distancing - reducing infection risk and achieving high patient satisfaction. Implementing a locker system will decrease differing instructions and positively impact waiting times to further reduce viral transmission risks. (Source: Europace)

Repolarization abnormalities at admission predict 30-day outcome in COVID-19
ConclusionsThe extent of repolarization abnormalities on an ECG at admission for COVID-19 is an independent predictor of 30-day mortality. New ECG abnormalities after COVID-19 infection are uncommon but may be associated with adverse outcome. Abstract Figure. (Source: Europace)

Usefulness of Goldberger"s triad to select dilated cardiomyopathy
ConclusionsConclusion: Goldberger"s triad is an insensitive marker for severe LV dysfunction. Using SV1 or SV2 +RV5 or RV6 ≥3.5mV and R/S ratio < 1 in lead V4 had a sensitivity of 50%. 85% patients had R/S ratio < 1 in lead V4. R/S ratio < 1 in lead V4 is a simple way to select dilated LV.

Optimum timing to assess ablation lesions with Late Gadolinium Enhancement MRl
ConclusionsOur results indicate that while ablation-induced atrial fibrosis appears to remain rather constant over time, LGE-MRI loses some of its capability to detect it. Thus, LGE-MRI 3 months post ablation may be more accurate in the detection of durable ablation lesions than LGE-MRI at later time points more than 12 months after ablation.

Clinical recurrence of palpitations following slow pathway ablation in patients with suspected paroxysmal supraventricular tachycardias but non-documented, non-inducible tachycardias
ConclusionsIn patients with high clinical suspicion of PSVT but non-documented and non-inducible arrhythmias, the presence of dual AV nodal physiology makes AVNRT a likely mechanism of the clinical tachycardia. Catheter ablation of slow pathway reduces the risk of recurrence to a level equivalent to those with inducible and ablated AVNRT.

Workflows and clinical utilization of dynamic mapping data in radiofrequency catheter ablation of cardiac arrhythmias
ConclusionsThis initial analysis demonstrated the diverse clinical utilization of LiveView dynamic display during RF catheter ablation procedures, including atrial and ventricular arrhythmias. Without causing significant changes to normal workflow, dynamic display of regional signals allows for rapid identification of ablation targets. When used during RF delivery, real-time assessment of regional activation patterns helped improve outcomes by rapidly identifying critical ablation location and ensuring successful lesion delivery. A further study that examines the impact of dynamic display on procedure efficacy may be warra...
