Abstract

AimsNo prior study has been adequately powered to evaluate real-world safety outcomes in those receiving adjunctive ablation lesions beyond pulmonary vein isolation (PVI). We sought to evaluate characteristics and in-hospital complications among patients undergoing PVI with and without adjunctive lesions.Methods and resultsPatients in the National Cardiovascular Data Registry AFib Ablation Registry undergoing first-time atrial fibrillation (AF) ablation between 2016 and 2020 were identified and stratified into paroxysmal (PAF) and persistent AF, and separated into PVI only, PVI + cavotricuspid isthmus (CTI) ablation, and PVI + adjunctive (superior vena cava isolation, coronary sinus, vein of Marshall, atypical atrial flutter lines, other). Adjusted odds of adverse events were calculated using multivariable logistic regression. A total of 50 937 patients [PAF: 30 551 (60%), persistent AF: 20 386 (40%)] were included. Among those with PAF, there were no differences in the adjusted odds of complications between PVI + CTI or PVI + adjunctive when compared with PVI only. Among persistent AF, PVI + adjunctive was associated with a higher risk of any complication [3.0 vs. 4.5%, odds ratio (OR) 1.30, 95% confidence interval (CI) 1.07-1.58] and major complication (0.8 vs. 1.4%, OR 1.56, 95% CI 1.10-2.21), while no differences were observed in PVI + CTI compared with PVI only. Overall, there was high heterogeneity in adjunctive lesion type, and those receiving adjunctive lesions had a higher comorbidity burden.ConclusionAdditional CTI ablation was common without an increased risk of complications. Adjunctive lesions other than CTI are commonly performed in those with more comorbidities and were associated with an increased risk of complications in persistent AF, although the current analysis is limited by high heterogeneity in adjunctive lesion set type.

33. Outcomes of hybrid surgical ablation and concomitant left atrial appendage exclusion in long‐standing persistent atrial fibrillation.

Abstract

Introduction: Management of patients with long‐standing persistent atrial fibrillation (LSPAF) presents a clinical challenge. Hybrid convergent ablation has been shown to have superior efficacy compared to endocardial‐only ablation. However, data on concomitant left atrial appendage (LAA) management along with hybrid ablation is sparse. Methods: We aimed to evaluate the effectiveness of concomitant hybrid convergent ablation and LAA clipping in patients with LSPAF. We conducted a retrospective analysis of all patients with LSPAF who underwent hybrid surgical ablation with LAA clipping at our institution. The primary endpoint was a recurrence of atrial arrhythmias at 12 months. Further, the durability of surgical left atrial posterior wall ablation was examined during the endocardial catheter ablation using standing electrophysiological criteria. Results: A total of 79 patients were included. Mean age was 63.5 ± 9.6 years, and 71% were males. LAA clipping was performed in 99% of patients. The mean time between the surgical and endocardial stages of the procedure was 2.6 ± 1.7 months. Persistent posterior wall activity was observed in 34.2% (n = 27/79) patients during the endocardial phase of the procedure. Cardiac implantable electronic device was used in 74% of patients for monitoring of recurrence of atrial fibrillation (AF). The primary effectiveness of AF freedom at 12 months was 73.8% (45/61). Over a 12‐month follow‐up period, 11.4% (9/79) of patients required repeat catheter ablation, of which 88.9% (8/9) had evidence of persistent posterior wall activity. Conclusion: Concomitant hybrid convergent ablation and LAA exclusion with an atrial clip provides reasonable long‐term AF‐free survival in patients with LSPAF. Persistent posterior wall activity is seen commonly in patients presenting with recurrent AF following hybrid convergent AF ablation. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Hemostasis following large‐bore femoral vein access remains a challenge. Manual compression has been the standard of care but requires bedside staff, prolonged bed rest, and longer length of stay. The LockeT is an external compression device that attempts to address these issues while achieving venous hemostasis. Objectives: We evaluate postprocedural hemostasis and vascular closure outcomes after using LockeT following cardiac electrophysiologic procedures. Methods: We performed a single‐center, observational study of patients who underwent vascular closure for electrophysiology procedures using LockeT. Postprocedural outcomes were subsequently analyzed. Results: We studied 102 patients (N) for whom LockeT was used to close 182 separate vascular access sites (n). Common procedures were atrial fibrillation ablation (56.9%, N = 58) and left atrial appendage occlusion (28.4%, N = 29). Most often, 8‐Fr [48.3% (n = 126)], 11‐Fr [27.2% (n = 71)], and 8.5‐Fr [16.9% (n = 44)] sheaths were used, with an average procedure time of 82.1 ± 29.4 min. Hemostasis was achieved in 97.8% (n = 187) of all LockeT cases. Time to ambulation and discharge were 3.93 ± 1.10 h and 8.1 ± 4.4 h, respectively. No major complications were noted. Postprocedurally, 52% (N = 53) of patients were discharged on the same day. There were no differences in hemostasis (p =.859) or ambulation times (p =.202) between procedure types. Conclusion: The LockeT can effectively close venous access sites with no major complications. [ABSTRACT FROM AUTHOR]
