Introduction: This study evaluated the real-world clinical and economic outcomes associated with the use of the ThermoCool Surround Flow (SF) and ThermoCool catheters in atrial fibrillation (AF) ablation.
Methods: Adults with AF who underwent catheter ablation between January 1, 2013, and December 31, 2016, in a hospital outpatient setting were identified from the Premier Healthcare Database. Using a search strategy of hospital-charge descriptors, patients were classified into two mutually exclusive groups: ThermoCool SF catheter and ThermoCool catheter. A generalized estimating equation was used to compare index admission cost. Survey logistic regression was used to compare the incidence of inpatient readmission, direct-current cardioversion (DCCV), and repeat ablation. Multivariable analyses were adjusted for hospital clustering and demographic, procedural, hospital, and comorbidity characteristics.
Results: There were 1,014 and 463 patients in the ThermoCool SF and ThermoCool groups, respectively. The ThermoCool SF group had significantly lower odds of all-cause (odds ratio [OR] 0.45; 95% CI 0.27-0.76) and cardiovascular-related readmissions (OR 0.45; 95% CI 0.21-0.96), and DCCV (OR 0.61; 95% CI 0.42-0.88) than the ThermoCool group. In patients susceptible to fluid overload, the ThermoCool SF group had significantly lower odds of 12-month all-cause (OR 0.42; 95% CI 0.23-0.75), cardiovascular-related (OR 0.31; 95% CI 0.10-0.92), and AF-related readmissions (OR 0.18; 95% CI 0.04-0.80), and DCCV (OR 0.52; 95% CI 0.31-0.87) than the ThermoCool group.
Conclusions: Using the ThermoCool SF catheter for AF ablation was significantly associated with improved clinical outcomes compared with the ThermoCool catheter.

Pulsed Field Ablation Using Focal Contact Force-Sensing Catheters for Treatment of Atrial Fibrillation: 1-Year Outcomes of the ECLIPSE AF Study.
Circ Arrhythm Electrophysiol

Background: Pulsed field ablation (PFA) is a promising treatment for atrial fibrillation. We report 1-year freedom from atrial arrhythmia outcomes using monopolar PFA delivered through 3 commercial, contact force-sensing focal catheters.
Methods: ECLIPSE AF (NCT04523545) was a prospective, single-arm, multicenter study evaluating acute and chronic safety and performance using the CENTAURI system to deliver focal PFA with TactiCath SE, StablePoint, and ThermoCool ST.
Hospital readmissions following catheter ablation for atrial fibrillation with THERMOCOOL™ STSF/ THERMOCOOL™ ST catheter with CARTO™ 3 system versus TactiCath™ catheter with EnSite™ system.

Radiofrequency (RF) catheter ablation (CA) is a mainstay treatment for atrial fibrillation (AF). RF catheters with contact force (CF) sensing technology and electroanatomical mapping systems enable real-time assessment of catheter tip-tissue interface CF, facilitating individualized and precise CA. This study examined inpatient hospital readmissions in patients with AF treated with THERMOCOOL™ ST/ THERMOCOOL™ STSF catheter with the CARTO™ 3 System versus TactiCath™ catheter with the EnSite™ System.

Article Synopsis
- A study evaluated the safety of four new radiofrequency ablation catheters used for treating atrial fibrillation (AF), analyzing 3,957 procedures to identify outcomes and procedure times.
- The results showed that while most catheters achieved a 99.5% success rate in isolating pulmonary veins, differences emerged in procedure duration and complications, with QDOT Micro and THERMOCOOL SMARTTOUCH SF demonstrating shorter fluoroscopic times and lower rates of cardiac tamponade compared to TactiFlex and TactiCath.
- Findings suggest that the type of catheter and mapping system used impacts both safety outcomes and procedural efficiency in real-world applications, with TactiFlex exhibiting the highest risk for complications like cardiac tamponade.
Evaluation of Ablation Parameters to Predict Irreversible Lesion Size During Pulsed Field Ablation.

Article Synopsis
- During pulsed field ablation (PFA), researchers studied the impact of various parameters like contact force (CF) and number of bursts on lesion size in beating hearts using a specialized catheter in swine.
- The study involved 11 closed-chest swine and tested different levels of CF and burst pulses, measuring lesion size after euthanization with a specific staining technique.
- Results showed that higher CF and more burst pulses significantly increased lesion depth, with a reliable formula predicting lesion size, while impedance decrease and electrode temperature were not effective predictors.

Article Synopsis
- Advances in ablation techniques and 3D mapping systems have improved treatments, but many patients still experience atypical atrial flutter (AAFL) after pulmonary vein isolation (PVI).
- In a study of 45 patients, 60% experienced arrhythmia recurrence within a year, although over 70% reported feeling better. Prescription of class I antiarrhythmics was linked to lower recurrence rates, while cardioversion during the procedure increased recurrence risk.
- Overall, while symptom improvement is noted, the long-term success of AAFL ablation isn't encouraging, indicating a need for better strategies to maintain sinus rhythm post-procedure.
