Very high ‐power short‐duration catheter ablation for treatment of cardiac arrhythmias: Insights from the FAST and FURIOUS study series
AbstractThe QDOT MICRO ™ Catheter is a novel open-irrigated contact force-sensing radiofrequency ablation catheter. It offers very high-power short-duration (vHPSD) ablation with 90 W for 4 s to improve safety and efficacy of catheter ablation procedures. Although the QDOT MICRO™ Catheter was mainly designed for pulmonary vein isolation (PVI) its versatility to treat atrial fibrillation (AF) and other types of arrhythmias was recently evaluated by the FAST and FURIOUS study series and other studies and will be presented in this article. Available study and registry data as well as case reports concerning u tiliza...

Successful ablation of a right concealed epicardial accessory pathway using ethanol infusion
ConclusionEndocardial ablation is challenging for epicardial APs related to cardiac structural variations. If small vascular branches near the earliest activation site can be found, EI can successfully ablate these types of epicardial APs. (Source: Journal of Cardiovascular Electrophysiology)

Comparison of pulsed ‐field ablation versus very high power short duration‐ablation for pulmonary vein isolation
ConclusionPulsed-field ablation and VHPSD-PVI seem to be highly effective and safe to achieve PVI in the setting of PAF and persAF with comparable arrhythmia-free survival. However, procedure duration for PFA PVI is significantly shorter and therefore may be of potential benefit. Compared to PFA VHPSD-PVI might ensure information on left atrial substrate allowing to target concomitant secondary tachycardias. (Source: Journal of Cardiovascular Electrophysiology)

Medical cardioversion of atrial fibrillation and flutter with class IC antiarrhythmic drugs in young patients with and without congenital heart disease
ConclusionsFlecainide was more effective than propafenone. We did not detect a difference in rate of conversion to sinus rhythm between patients with and without CHD and were likely underpowered to do so, however, there was a trend toward decreased likelihood of success in patients with CHD. That said, medical therapy was effective in>50% of patients with CHD with AF. (Source: Journal of Cardiovascular Electrophysiology)

Factors predicting the progression from paroxysmal to persistent atrial fibrillation despite an index catheter ablation
ConclusionThe progression from PAF to PersAF after catheter ablation is associated with a larger LA diameter, history of thyroid disease, and the presence of non-PV triggers. Meticulous preprocedural evaluation, patient selection, and comprehensive provocation tests during catheter ablation are recommended. (Source: Journal of Cardiovascular Electrophysiology)

Cost ‐effectiveness analysis of leadless cardiac resynchronization therapy
ConclusionWithin the model limitations, these findings support the use of WiSE-CRT in indicated patients from an economic standpoint. However, improving battery technology should be prioritized to maximize cost-effectiveness in times when health services are under significant financial pressures.

Early recurrence of atrial tachyarrhythmia indicates pulmonary vein reconduction independent of blanking period duration in the RACE ‐AF trial
ConclusionEarly ATA indicates PVR, and the positive predictive value is independent of the blanking period duration. Altogether, the results of this study support substantially shortening the blanking period after PVI for paroxysmal AF. (Source: Journal of Cardiovascular Electrophysiology)

LBBB and heart failure —Relationships among QRS amplitude, duration, height, LV mass, and sex
ConclusionTrue LBBB criteria do not exclude HF patients with increased LV mass. QRS amplitudes do not correlate with height or LV mass. Height does not affect QRSd. However, QRSd correlates with LV size. QRSd normalized for LV mass results in 24% greater value in women in the direction of sex-specific responses. LV mass may be a significant nonelectrical modifier of QRSd for CRT. (Source: Journal of Cardiovascular Electrophysiology)

Characteristics of tissue temperature during ablation with THERMOCOOL SMARTTOUCH SF versus TactiCath versus QDOT MICRO catheters (Qmode and Qmode+): An in vivo porcine study
ConclusionThis study revealed distinct tissue temperature patterns during HSPD and vHPSD ablations with the three catheters, affecting lesion effectiveness and collateral damage based on Tmax and/or t −T ≥ 50°C. These findings provide key insights into the safety and efficacy of AF ablation with these four settings. (Source: Journal of Cardiovascular Electrophysiology)

Quantitative assessment of transient autonomic modulation after single ‐shot pulmonary vein isolation with pulsed‐field ablation
ConclusionPVI with the FarapulseTM PFA system is associated with only transitory and short-lasting vagal effects on the ANS which recover almost completely within a few minutes after ablation. The impact of this phenomenon on AF outcome needs to be further investigated. (Source: Journal of Cardiovascular Electrophysiology)
