Hybrid ablation versus transcatheter ablation for atrial fibrillation: A meta-analysis.

ABSTRACT:

Background

Despite the successful creation of complex lesion sets during hybrid ablation (HA), reoccurrence of atrial fibrillation (AF), and/or atrial arrhythmia and procedural complications still occur. The main objective of this study was to compare the efficacy and safety between HA and transcatheter ablation (TA).

Methods

We searched Pubmed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) database up to October 2017. Studies that satisfied our predefined inclusion criteria were included. Of the 894 records, 4 studies encompassing 331 patients were included in our study. We assessed pooled data using random-effect or fixed-effect model. The main endpoint was freedom of atrial arrhythmia after follow-up duration, secondary results were procedure time and intraoperative and postoperative adverse events. Similarly, tertiary outcomes were endocardial time, fluoroscopy time, and postoperative hospitalization.

Results

Compared with TA, HA treatment through mini-thoracotomy access improved superiority in freedom of atrial arrhythmia after follow-up duration (odds ratio [OR]?=?6.67, 95% confidence interval [CI]: 2.63-16.90), but HA increased the incidence of intraoperative and postoperative adverse events for AF patients (OR?=?2.98, 95% CI: 1.30-6.83). HA through either mini-thoracotomy or transdiaphragmatic/subxiphoid access had longer procedure time and postoperative hospitalization than TA. However, endocardial time was shorter than TA.

Conclusions

For AF patients, HA possessed of an overall superior outcome using mini-thoracotomy way to TA. Although HA had longer procedure time, it yielded a reduction in endocardial time. Meanwhile, we should pay attention to the significantly high risk of intraoperative and postoperative adverse events that the HA generated.

Project description:BackgroundBoth catheter left atrial appendage occlusion combined with ablation (COA) and thoracoscopic surgical left atrial appendage clipping combined with ablation (TCA) have shown favorable outcomes in management of patients with atrial fibrillation (AFib). However, studies comparing the endpoints of both techniques are still lacking. Herein, a meta-analysis of safety and efficacy outcomes of COA versus TCA was performed in patients with AFib.MethodsPubmed, Embase, Cochrane, and Web of Science databases were searched for retrieving potential publications. The primary outcome was the incidence of stroke during follow-up period of at least 12 months. Secondary outcomes were acute success rate of complete left atrial appendage (LAA) closure by COA or TCA, postprocedural mortality and complications, and all-cause mortality during follow-up period of at least 12 months.Results19 studies of COA containing 1,504 patients and 6 studies of TCA with 454 patients were eligible for analysis. No significant difference in stroke and all-cause mortality was found in patients undergoing COA versus TCA after at least a 12-month follow-up (stroke: p = 0.504; all-cause mortality: p = 0.611). COA group had a higher acute success rate compared with TCA group (p = 0.001). COA placed the patients at a higher risk of hemorrhage during the postprocedural period compared with TCA (p = 0.023). A similar risk of other postprocedural complications (stroke/transient ischemic attack and pericardial effusion) and mortality was found in the COA group in comparison with TCA group (p>0.05).ConclusionThis meta-analysis showed that COA and TCA did not differ in stroke prevention and all-cause mortality in patients with AFib after a follow-up of at least 12 months. Postprocedural complications and mortality were almost comparable between the two groups. In the near future, high-quality randomized controlled trials exploring the optimal surgical strategies for AFib and endpoints of different procedures are warranted.Systematic review registration[https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42022325497].

Project description:IntroductionAtrial Fibrillation (AF) is a common tachyarrhythmia affecting 33 million people worldwide. Hybrid AF ablation utilises a surgical (epicardial) ablation followed by an endocardial catheter-based ablation. The aim of this systematic review and meta-analysis is to summarize the literature reporting mid-term freedom from AF following hybrid ablation.MethodsAn electronic search of databases was performed to identify all relevant studies providing mid-term (2 year) outcomes following hybrid ablation for AF. The primary study outcome was to assess the mid-term freedom from AF following hybrid ablation, utilising the metaprop function on Stata® (Version 17.0, StataCorp, Texas, USA). Subgroup analysis was performed to assess the impact of various operative characteristics on mid-term freedom from AF. The secondary outcomes assessed mortality and procedural complication rate.ResultsThe search strategy identified 16 studies qualifying for inclusion in this meta-analysis, with 1242 patients in total. The majority of papers were retrospective cohort studies (15) and one study was a randomized control trial (RCT). The mean follow up was 31.5 ± 8.4 months. Following hybrid ablation, the overall mid-term freedom from AF was 74.6% and 65.4% for patients off antiarrhythmic drugs (AAD). Actuarial freedom from AF was 78.2%, 74.2% and 73.6% at 1, 2 and 3 years respectively. No significant differences in mid-term freedom from AF based epicardial lesion set (box vs pulmonary vein isolation) or Left atrial appendage/Ganglionated Plexus/Ligament of Marshall ablation or staged vs concomitant procedures. There were 12 deaths overall following the hybrid procedure with a pooled complication rate of 5.53%.ConclusionHybrid AF ablation offers promising mid-term freedom from AF reported at a mean follow-up of 31.5 months. The overall complication rate remains low. Further analysis of high-quality studies with randomized data and long-term follow up will help verify these results.
