Abstract
A significant proportion of patients who suffer from atrial fibrillation (AF) and are in need of thromboembolic protection are not treated with oral anticoagulation or discontinue this treatment shortly after its initiation. This undertreatment has not improved sufficiently despite the availability of direct oral anticoagulants which are associated with less major bleeding than vitamin K antagonists. Multiple reasons account for this, including bleeding events or ischaemic strokes whilst on anticoagulation, a serious risk of bleeding events, poor treatment compliance despite best educational attempts, or aversion to drug therapy. An alternative interventional therapy, which is not associated with long-term bleeding and is as effective as vitamin K anticoagulation, was introduced over 20 years ago. Because of significant improvements in procedural safety over the years, left atrial appendage closure, predominantly achieved using a catheter-based, device implantation approach, is increasingly favoured for the prevention of thromboembolic events in patients who cannot achieve effective anticoagulation. This management strategy is well known to the interventional cardiologist/electrophysiologist but is not more widely appreciated within cardiology or internal medicine. This article introduces the devices and briefly explains the implantation technique. The indications and device follow-up are more comprehensively described. Almost all physicians who care for adult patients will have many with AF. This practical guide, written within guideline/guidance boundaries, is aimed at those non-implanting physicians who may need to refer patients for consideration of this new therapy, which is becoming increasingly popular.

Rev Cardiovasc Med 2024; 25:10. [PMID: 39077666 PMCID: PMC11262385 DOI: 10.31083/j.rcm2501010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 08/21/2023] [Accepted: 08/25/2023] [Indexed: 07/31/2024] Open
Abstract
Background The combination of left atrial appendage closure (LAAC) and catheter ablation (CA) in a single procedure is a safe and effective form of treatment for atrial fibrillation (AF). However, several findings have argued that LAAC might increase the risk of AF recurring. Therefore, this study investigated the impact of insufficient ablation on AF recurrence after the hybrid procedures of CA and LAAC. Methods We reviewed 107 consecutive patients with AF who received the CA and LAAC hybrid procedures (combined group). In the case-control study, another 107 patients who underwent only CA (ablation group) were successfully matched using propensity score matching. After correcting the insufficient ablation, 107 consecutive patients were enrolled prospectively. During the follow-up period, postprocedural 24-hour monitor recordings and a portable electrocardiogram (ECG) monitoring device were used to detect AF recurrence. Transesophageal echocardiography was used to evaluate LAAC. Results The combined group showed an increase in the risk of AF recurrence after 539.2 ± 304.4 days of follow-up (29.9% vs. 15.9%, p < 0.05). Interestingly, the duration of the procedure was not significantly prolonged when LAAC was added after CA in the combined group, while there was a higher number of ablating attempts, duration of ablation, and additional ablation in the ablation group for both radiofrequency and cryoballoon ablation. After correcting for the insufficient ablation, the corrected group showed a significant decrease in AF recurrence after 420.4 ± 204.8 days of follow-up. Conclusions Insufficient ablation is common when combining CA and LAAC and may lead to the recurrence of atrial fibrillation. It should be corrected intentionally by sufficient ablation of the pulmonary vein antrum and additional ablation. Clinical Trial Registration The prospective study is a sub-study of our CAGEDAF study that has already been registered (ChiCTR2000039746).

Trends Cardiovasc Med 2023:S1050-1738(23)00100-7. [PMID: 37981202 DOI: 10.1016/j.tcm.2023.11.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 11/08/2023] [Accepted: 11/14/2023] [Indexed: 11/21/2023]
Abstract
Stroke prevention and symptom control are two integral pillars in atrial fibrillation (AF) management. Percutaneous left atrial appendage occlusion (LAAO) is effective at reducing stroke risk in high-risk patients with AF who cannot tolerate oral anticoagulant therapy, whilst catheter ablation is effective at reducing AF burden and improving quality-of-life in patients who remain symptomatic despite medical therapy. If both procedures are indicated in an individual patient, they have traditionally been performed on separate occasions, due to long cumulative procedural times, itself associated with thromboembolic risk. Recently, with the advancement of procedural techniques, the concept of concurrent LAAO and AF catheter ablation has gained traction. This review summarises the evidence for and against concurrent LAAO and AF catheter ablation, discussing procedural considerations, including procedural sequencing and post-procedural antithrombotic therapy, safety and efficacy outcomes, and future directions in the field.

Abstract
Background A one-stop procedure involving catheter ablation and left atrial appendage occlusion (LAAO) is an option for high-risk atrial fibrillation patients. Few studies have reported the efficacy and safety of cryoballoon ablation (CBA) combined with LAAO, and no studies have compared the combination of LAAO with CBA or radiofrequency ablation (RFA). Methods A total of 112 patients were enrolled in the present study; 45 patients received CBA combined with LAAO (group 1), and 67 patients received RFA combined with LAAO (group 2). Patient follow-up was performed for 1 year to detect peri-device leaks (PDLs) and safety outcomes (defined as a composite of peri-procedural and follow-up adverse events). Results The number of PDLs at the median 59 days follow-up was comparable between the two groups (33.3% in group 1 vs. 37.3% in group 2, p = 0.693). Safety outcomes were also comparable between the two groups (6.7% in group 1 vs. 7.5% in group 2, p = 1.000). Multivariable regression showed that PDLs risk and safety outcomes were all similar between the two groups. Subgroup analysis of PDLs indicated no significant differences. Follow-up safety outcomes were related to anticoagulant medication, and patients without PDLs were more likely to discontinue antithrombotic therapy. The total procedure and ablation times were all significantly shorter for group 1. Conclusion When compared with left atrial appendage occlusion combined with radiofrequency, left atrial appendage occlusion combined with cryoballoon ablation has the same risk of peri-device leaks and safety outcomes, but the procedure time was significantly reduced.

Clinical Influence of Ethanol Infusion in the Vein of Marshall on Left Atrial Appendage Occlusion: Results of Feasibility and Safety during Implantation and at 60-Day Follow-Up. J Clin Med 2023; 12:jcm12051960. [PMID: 36902746 PMCID: PMC10004188 DOI: 10.3390/jcm12051960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 02/22/2023] [Accepted: 02/27/2023] [Indexed: 03/06/2023] Open
Abstract
BACKGROUND Ethanol infusion in the vein of Marshall (EI-VOM) has the advantages of reducing the burden of atrial fibrillation (AF), decreasing AF recurrence, and facilitating left pulmonary vein isolation and mitral isthmus bidirectional conduction block. Moreover, it can lead to prominent edema of the coumadin ridge and atrial infarction. Whether these lesions will affect the efficacy and safety of left atrial appendage occlusion (LAAO) has not yet been reported. OBJECTIVES To explore the clinical outcome of EI-VOM on LAAO during implantation and after 60 days of follow-up. METHODS A total of 100 consecutive patients who underwent radiofrequency catheter ablation combined with LAAO were enrolled in this study. Patients who also underwent EI-VOM at the same period of LAAO were assigned to group 1 (n = 26), and those who did not undergo EI-VOM were assigned to group 2 (n = 74). The feasibility outcomes included intra-procedural LAAO parameters and follow-up LAAO results involving device-related thrombus, a peri-device leak (PDL), and adequate occlusion (defined as a PDL ≤ 5 mm). Safety outcomes were defined as the composites of severe adverse events and cardiac function. Outpatient follow-up was performed 60 days post-procedure. RESULTS Intra-procedural LAAO parameters, including the rate of device reselection, rate of device redeployment, rate of intra-procedural PDLs, and total LAAO time, were comparable between groups. Furthermore, intra-procedural adequate occlusion was achieved in all patients. After a median of 68 days, 94 (94.0%) patients received their first radiographic examination. Device-related thrombus was not detected in the follow-up populations. The incidence of follow-up PDLs was similar between the two groups (28.0% vs. 33.3%, p = 0.803). The incidence of adequate occlusion was comparable between groups (96.0% vs. 98.6%, p = 0.463). In group 1, none of the patients experienced severe adverse events. Ethanol infusion significantly reduced the right atrial diameter. CONCLUSIONS The present study showed that undergoing an EI-VOM procedure did not impact the operation or effectiveness of LAAO. Combining EI-VOM with LAAO was safe and effective.

Abstract
BACKGROUND Patients with drug-refractory atrial fibrillation (AF) and pre-existing left atrial appendage occluder (LAAO) device may need pulmonary vein isolation (PVI). In this pioneer study, we investigated the impact of pre-existing LAAO on AF substrates and outcomes of PVI. METHODS From our AF registry, 65 drug-refractory patients with LAAO (72.1±11.4 years old; CHA2DS2-VASc score 3.7±2.1) were included for PVI. A balanced control group with 124 patients without LAAO receiving PVI (70.9±10.2 years old, CHA2DS2-VASc 3.6±1.9) were included for comparison. RESULTS We found PVI is feasible in patients with AF with pre-existing LAAO without new peridevice leak. Two patients with LAAO and one without LAAO had stroke during the procedure (2/65 vs 1/124, p=0.272). Complete isolation of left-sided PVs might not be achieved if the device covered the ridge joining the left atrial (LA) appendage to the body of LA. Local electrogram could be detected over LAAO and there was propagation of conduction over the occluder either under sinus rhythm or under atrial arrhythmia. LAAO might modulate LA substrate and induce peridevice fibrosis, peridevice LA flutter and complex fractionate atrial electrogram. The AF recurrent rate at 1 year was similar between the two groups (9.2% vs 8.8%). CONCLUSIONS This pioneer study first showed impacts of LAAO on LA substrate and PVI procedure.

Abstract
Objectives To compare patients with atrial fibrillation (AF) undergoing left atrial appendage closure (LAAC) with catheter ablation (CA) and those without CA. Background The CA of AF may cause ridge edema, which may affect the safety of LAAC. Methods Patients with AF (N = 98) who underwent LAAC (combined CA + LAAC procedure group; N = 51) or alone (LAAC group; N = 47) received pre-procedural, intra-procedural, and 6 week post-procedural transesophageal echocardiography (TEE). The depth and ostial diameter of LAA, device compression, residual leak, and ridge thickness were evaluated in the patients who had undergone combined and alone procedures, as well as images of LAA and primary clinical characteristics. Results A residual leak was identified in 27 patients at 6 weeks after implantation by TEE (19 in the combined procedures group and eight in the alone group; p = 0.04). The combined procedure group had a significantly higher rate of a new residual leak than the alone group (25.5 vs. 8.5%; p = 0.03). Meanwhile, compared with at the time of implant, a smaller amount of device compression ratio was significant after 6 weeks (22.44 ± 3.90 vs. 19.59 ± 5.39; p = 0.03). There was no significant difference between both groups in all-cause mortality, cardiovascular mortality, and TIA/stroke/system embolism. Conclusion The combined procedures of CA and LAAC for AF are feasible and safe; however, during the follow-up period, we found that the resolution of ridge edema caused by CA might cause an increased residual leak and a smaller device compression ratio.

Abstract
BACKGROUND Left atrial appendage closure (LAAC) combined with radiofrequency catheter ablation is an emerging one-stop hybrid procedure for non-valvular atrial fibrillation (AF). This study was performed to compare the efficacy and safety of the Watchman device vs. the LAmbre device for this combined procedure. METHODS Two hundred and thirty two patients with AF who underwent the combined procedure were enrolled and divided into two subgroups depending on the device choice: the Watchman-combined group (n = 118) and the LAmbre-combined group (n = 114). The periprocedural and follow-up adverse events in both groups were documented. RESULTS The mean CHA2DS2-VASc score and HAS-BLED score in the Watchman-combined group and LAmbre-combined group were 3.7 ± 1.5 vs. 3.8 ± 1.5 and 2.5 ± 1.1 vs. 2.3 ± 1.1, respectively (all P > 0.05). Successful LAAC was achieved in all patients. The rate of major periprocedural complications and AF recurrence at 6 months post-procedure were similar between the Watchman-combined group and LAmbre-combined group (0.8 vs. 0.9%, P = 1.00; 22.0 vs. 15.8%, P = 0.23). During 2.6 ±0 .7 vs.1.6 ± 1.6 years follow-up, the rate of major clinical adverse events, including stroke and major bleeding, were comparable between the Watchman-combined group and the LAmbre-combined group (2.6 vs. 1.1% per 100 patient-years, P = 0.33). The intraprocedural peri-device leakage (PDL) rate was similar between the Watchman-combined group and the LAmbre-combined group (5.1 vs. 6.1%, P = 0.73), but the PDL rate was significantly higher at 3-6 months transesophageal echocardiography (TEE) follow-up than the intraprocedural PDL rate in both groups (21.6 vs. 5.1%; 36.6 vs. 6.1%, respectively), with a more obvious increase in minimal PDL rate in the LAmbre-combined group than the Watchman-combined group (36.6 vs. 21.6%, P < 0.05). CONCLUSION The Watchman and LAmbre devices were comparable in efficacy and safety for the combined procedure. The minimal PDL rate at short-term TEE follow-up was higher in the LAmbre-combined group than the Watchman-combined group.

Abstract
BACKGROUND Catheter ablation (CA) and left atrial appendage closure (LAAC) require transseptal access; combining both in a single procedure may have advantages. However, the safety of this approach has not been extensively studied. The objective of this study was to compare in hospital outcomes among patients receiving CA, LAAC, and combination of both treatments on the same day. METHODS We conducted a retrospective cohort analysis of the National Inpatient Sample database. The primary outcome was the presence of major adverse cardiovascular and cerebrovascular events (MACCE) during index hospitalization. Secondary outcomes included stroke, pericardial effusion, pericardiocentesis, and bleeding. RESULTS A total of 69,285 hospitalizations with AF were included in the analysis, of which 71.7% received LAAC, 27.8% received CA, and 0.5% received combination of both treatments on the same day. MACEE (OR, 1.63; 95% CI, 0.39-6.70), stroke (OR, 2.98; 95% CI, 0.55-16.01), pericardial effusion (OR, 0.33; 95% CI, 0.07-1.41), pericardiocentesis (OR, 1.00; 95% CI, 0.25-3.86), and bleeding (OR, 3.25; 95% CI, 0.87-12.07) did not differ significantly between CA and combination treatment. Similarly, MACCE (OR, 1.11; 95% CI, 0.28-4.41), stroke (OR, 1.03; 95% CI, 0.24-4.35), pericardial effusion (OR, 0.45; 95% CI, 0.11-1.90), pericardiocentesis (OR, 0.63; 95% CI, 0.14-2.83), and bleeding (OR, 2.04; 95% CI, 0.65-6.39) did not differ significantly between LAAC and combination treatment. CONCLUSIONS The combined approach is infrequently used in clinical practice (< 1%). However, major life-threatening adverse events did not differ between CA and LAAC when performed in isolation or combined in a single procedural stage on the same day.

Concomitant transcatheter occlusion versus thoracoscopic surgical clipping for left atrial appendage in patients undergoing ablation for atrial fibrillation: A meta-analysis. Front Cardiovasc Med 2022; 9:970847. [PMID: 36148075 PMCID: PMC9485627 DOI: 10.3389/fcvm.2022.970847] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Accepted: 08/16/2022] [Indexed: 11/17/2022] Open
Abstract
Background Both 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. Methods Pubmed, 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. Results 19 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). Conclusion This 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.

Effect of catheter ablation combined with left appendage occlusion for non-valvular atrial fibrillation: a meta-analysis. J Cardiothorac Surg 2022; 17:132. [PMID: 35642039 PMCID: PMC9158183 DOI: 10.1186/s13019-022-01885-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 05/19/2022] [Indexed: 11/26/2022] Open
Abstract
Objective To estimate the effect of catheter ablation combined with left appendage occlusion in the treatment of non-valvular atrial fibrillation (NVAF) by a method of meta-analysis. Methods Pubmed, Embase, and Cochrane Library were searched for the studies about catheter ablation combined with left appendage occlusion in treating NVAF. The data analysis was performed using R 4.0.5 software. The retrieval time was from inception to May 12, 2021. Results A total of 18 published studies were identified in the meta-analysis, including 1385 participants. During the perioperative period of catheter ablation combined with left appendage occlusion in treating NVAF, the pooled incidences of pericardial effusion, major or minor bleeding events, and residual flow documented were 0.5%(95%CI 0.0002–0.0099), 1.42%(95% CI 0.00–0.04), 7.24%(95% CI 0.0447–0.0975), respectively. During the follow-up, the incidences of all-cause mortality, embolism events, and bleeding events were 0.32%(95%CI 0.0000–0.0071), 1.29%(95%CI 0.0037–0.0222), 2.07%(95% CI 0.0075–0.0339), respectively. In the follow-up period of the transesophageal echocardiography, the most complication was residual flow event with an incident rate of 10.80%(95% CI 0.054–0.1620). The maximum occurrence probability of residual flow events was 17.92% (95% CI 0.1133–0.2452). Moreover, the incident rate of NVAF recurrence was 29.23% (95% CI 0.2222–0.3623). Conclusion The meta-analysis suggests that the “one-stop” procedure is effective for those patients undergoing NVAF. However, Patients with more residual blood flow have a higher incidence of bleeding complications. More studies are warranted to verify the safety and efficacy of catheter ablation combined with left appendage occlusion in terms of the “one-stop” procedure.

Abstract
Left atrial appendage (LAA) occlusion (LAAO) is used to close the finger-like extension from the left atrium with occlusion devices to block the source of thrombosis. However, selection of the devices size is not easy due to various anatomical changes. The purpose of this study is patient-specific, computed tomography angiography (CTA)-based, three-dimensionally (3D) printed LAAO phantoms were applied pre-procedure to determine the size. Ten patients were enrolled prospectively in March 2019 and December 2020. The cardiac structure appearing in CTA was first segmented, and the left atrium and related structures in the LAAO procedure were modeled. The phantoms were fabricated using two methods of fused deposition modeling (FDM) and stereolithography (SLA) 3D printers with thermoplastic polyurethane (TPU) and flexible resin materials and evaluated by comparing their physical and material properties. The 3D-printed phantoms were directly used to confirm the shape of LAA, and to predict the device size for LAAO. In summary, the shore A hardness of TPU of FDM was about 80-85 shore A, and that of flexible resin of SLA was about 50-70 shore A. The measurement error between the STL model and 3D printing phantoms were 0.45 ± 0.37 mm (Bland-Altman, limits of agreement from - 1.8 to 1.6 mm). At the rehearsal, the estimations of device sizes were the exact same with those in the actual procedures of all 10 patients. In conclusion, simulation with a 3D-printed left atrium phantom could be used to predict the LAAO insertion device size accurately before the procedure.

Impact of Left Atrial Appendage Closure Combined with Catheter Ablation on Endocrine and Mechanical Cardiac Function in Patients with Atrial Fibrillation. J Interv Cardiol 2022; 2022:3932912. [PMID: 35360092 PMCID: PMC8957483 DOI: 10.1155/2022/3932912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Revised: 02/02/2022] [Accepted: 02/22/2022] [Indexed: 11/18/2022] Open
Abstract
Background The combined procedure of left atrial appendage closure (LAAC) and catheter ablation (CA) is a safe and feasible therapy to treat patients with atrial fibrillation (AF). However, the effect of the combined procedure on cardiac function remains unclear. This study aimed to investigate the changes in endocrine and mechanical function of the heart following the combined procedure. Methods This retrospective study included 62 consecutive patients who underwent the combined procedure of AF ablation and WATCHMAN LAAC and 62 sex and age-matched patients who only received AF ablation. During follow-up, patients were examined for brain natriuretic peptide (BNP) levels to represent endocrine cardiac function. Mechanical cardiac function was assessed during echocardiographic examination by means of the LA ejection fraction, LA strain (Ƹ), and LA strain rate (SR). Results (1) The BNP levels decreased acutely after the procedure, rose at day 3 postoperation, but trended downwards at 3 months postoperation in both groups. No significant difference was observed between the two groups. (2) LA ejection fraction, LA Ƹ, and SR exhibited a continuous upward trend over a 3-month follow-up in both groups. There was no significant difference in LA ejection fractions, SRe (the parameter of LA conduit function), and SRa (the parameter of LA booster pump function) between the two groups. However, the Ƹ and SRs (the parameters of LA reservoir function) improved in patients treated with CA alone. Conclusions The combined procedure of LAAC and CA significantly improved the endocrine and mechanical function of the heart. Compared to simple CA, based on CA with LAAC intervention, it does not significantly change LA endocrine function but may lead to a decline in the LA reservoir function.

Abstract
BACKGROUND Combined ablation and left atrial appendage closure (LAAC) is an alternative for atrial fibrillation patients with a high risk of stroke. However, the long-term outcomes of this combined procedure remain elusive. METHODS PubMed, Embase, Cochrane Library, and Web of Science were systematically searched from the establishment of databases to 1 January 2021. Studies on the long-term (defined as a mean follow-up of approximately 12 months or longer) efficacy and safety outcomes of combined ablation and LAAC were included. RESULTS A total of 16 studies comprising 1428 patients were enrolled. The pooled long-term freedom rate from atrial arrhythmia was 0.66 (95% confidence interval [CI]: 0.59-0.71), long-term successful rate sealing of LAAC was 1.00 (95% CI: 1.00-1.00), and ischemic stroke/transient ischemic attack/systemic embolism during follow-up was 0.01 (95% CI: 0.00-0.02). Meanwhile, of the periprocedural adverse events, phrenic nerve palsy, intracoronary air embolus, device embolization, and periprocedural death had a rate of 0.00 (95% CI: 0.00-0.00), procedure-related bleeding events of 0.03 (95% CI: 0.02-0.04), and pericardial effusion requiring or not requiring intervention of 0.00 (95% CI: 0.00-0.01). Moreover, for the long-term adverse events, device dislocation, intracranial bleeding, pericardial effusion requiring or not requiring intervention, and all-cause mortality had a rate of 0.00 (95% CI: 0.00-0.00), device embolization of 0.01 (95% CI: 0.00-0.01), and other bleeding events of 0.01 (95% CI: 0.00-0.03). CONCLUSION This meta-analysis suggests that the combined atrial ablation and LAAC is an effective and safe strategy with long-term benefits.

Abstract
Introduction: Long-term freedom from atrial fibrillation (AF) after catheter ablation and, consequently, the potential for stroke reduction remain unpredictable. Recently, left atrial appendage closure (LAAC) became an effective mechanical alternative to oral anticoagulation (OAC) for stroke prevention in AF patients. Objective: This study aims to evaluate the feasibility and safety of combined treatment for AF with catheter ablation (CA) with the high-power short duration technique associated with LAAC in one single procedure. Methods: Patients with non-valvular AF who underwent combined CA and LAAC procedure were included in the retrospective observational study. Between April 2018 and October 2020, 13 patients with AF were included, eight (61,54%) males, eight (61.54%) with persistent AF (PersAF), mean age 68.54 (65–84) years old, mean time from AF diagnosis to treatment 13.08 (3–33) months, mean CHA2VASC2 5.08 (3–7), all patients with coronary or vascular disease, 12 (92.31%) with hypertension, five (38.46%) with left ventricular dysfunction, four (30.77%) prior strokes using OAC and four (30.77%) patients with diabetes. Indications for LAAC included history of contraindication to OAC because of severe bleeding in eight (61.54%), previous stroke in four (30.77%) and two (13.08%) patients with LAA thrombus, despite the use of two different OAC (one associated with bleeding). One patient had a pseudoaneurysm in femoral artery, and two patients died of non-procedure complications after 30 days. At six months, angiotomography showed successful complete sealing of the LAA in seven (77.72%) of nine patients evaluated, and the two patients without it had a leak of less than 2 mm. After mean follow-up of 14 months (five to 33), 10 (90.91%) of the 11 patients were in sinus rhythm. Three (27.27%) patients, one in blanking period, recovered sinus rhythm after amiodarone. No cardioembolic or bleeding events occurred. Conclusion: In this small observational study, we showed the feasibility and safety of the combined therapy with AF catheter ablation with LAAC with a high rate of sinus rhythm and no cardioembolic event.

Abstract
Atrial fibrillation (AF), the most common arrhythmia, is a major cause of stroke and systemic embolism. Left atrial appendage closure (LAAC) has been proved to be noninferior to traditional Vitamin K antagonists (VKAs) as well as novel oral anticoagulants (NOACs), which is becoming an important alternative to prevent stroke in non‐valvular AF. Catheter‐based AF ablation (CA) is recommended to be a standard of care in patients with AF refractory to drug therapy due to a better rhythm control and improvement of life quality than antiarrhythmic drugs. Theoretically, the one‐stop combination with LAAC and CA tends to bring more benefits in patients with AF, as it not only relieves symptoms, but also reduces the risk of stroke significantly. However, several important questions still need to be considered in the combination procedure although quite a few attempts have already been made in clinical practice. This review provides a comprehensive update on the concept, technique, perioperative management, benefits and other critical issues of the “one‐stop” procedure.

Impact of anticoagulation strategy after left atrial appendage occlusion in patients requiring direct current cardioversion. J Cardiovasc Electrophysiol 2021; 32:737-744. [PMID: 33448508 DOI: 10.1111/jce.14889] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Revised: 12/18/2020] [Accepted: 12/29/2020] [Indexed: 10/22/2022]
Abstract
INTRODUCTION Current guidelines recommend adequate anticoagulation for at least 3 weeks pre- and 4 weeks post-direct current cardioversion (DCCV) to reduce thrombo-embolic risk in patients with atrial fibrillation (AF) lasting greater than 48 h. No specific recommendations exist for DCCV in patients that have undergone left atrial appendage occlusion (LAAO), many of whom are ineligible for anticoagulation. This study aims to observe the efficacy and safety of DCCV post-LAAO in everyday clinical practice. METHODS This prospective multicenter registry included DCCVs in patients post-LAAO. Imaging strategy or anticoagulation treatment around DCCV were analyzed. Complications during 30-day follow-up were registered. DCCVs performed in accordance with current guidelines for the general AF population were compared to DCCVs performed deviating from these guidelines. RESULTS In 93 patients (age 65 ± 17 years, CHA2 DS2 -VASC 3.0 ± 1.3) 284 DCCVs were performed between 2010 and 2018, in 271 sinus rhythm was restored. A wide variety of imaging or anticoagulation strategies around DCCV was observed; in 128 episodes strategies deviated from current guidelines. No thrombo-embolic events were observed after any DCCV during 30-day follow-up. In 34 DCCVs trans-esophageal echocardiography (TOE) was performed before DCCV to exclude cardiac thrombi and/or (re-)verify adequate device positioning. In two patients without post-LAAO imaging before DCCV, a device rotation or embolization was observed during scheduled TOE after LAAO. CONCLUSION DCCV in AF patients after LAAO is highly effective. No thrombo-embolic events were observed in any patient in this observational cohort, regardless of the periprocedural anticoagulation or imaging strategy. Confirmation of adequate device positioning at least once before DCCV seems recommendable.

Cost-effectiveness of combined catheter ablation and left atrial appendage closure for symptomatic atrial fibrillation in patients with high stroke and bleeding risk. Am Heart J 2021; 231:110-120. [PMID: 32822655 DOI: 10.1016/j.ahj.2020.08.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Accepted: 08/12/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND Combined catheter ablation (CA) and left atrial appendage closure (LAAC) have been proposed for management of symptomatic atrial fibrillation (AF) in patients with high stroke and bleeding risk. We assessed the cost-effectiveness of combined CA and LAAC compared with CA and standard oral anticoagulation (OAC) in symptomatic AF. METHODS A Markov model was developed to assess total costs, quality-adjusted life-years (QALYs), and the incremental cost-effectiveness ratio among 2 post-CA strategies: (1) standard OAC and (2) LAAC (combined CA and LAAC procedure). The base-case used a 10-year time horizon and consisted of a hypothetical cohort of patients aged 65 years with symptomatic AF, with high thrombotic (CHA2DS2-VASc = 3) and bleeding risk (HAS-BLED = 3), and planned for AF ablation. Values for transition probabilities, utilities, and costs were derived from the literature. Costs were converted to 2020 US dollars. Half-cycle correction was applied, and costs and QALYs were discounted at 3% annually. Sensitivity analyses were performed for significant variables and scenario analyses for higher embolic risk. RESULTS In the base-case cohort of 10,000 patients followed for 10 years, total costs for the LAAC strategy were $29,027 and for OAC strategy were $27,896. The LAAC strategy was associated with 122 fewer disabling strokes and 203 fewer intracranial hemorrhages per 10,000 patients compared with the OAC strategy. The LAAC strategy had an incremental cost-effectiveness ratio of $11,072/QALY. In sensitivity analyses, although cost-effectiveness was highly dependent on the risk of intracranial hemorrhage in the LAAC strategy and the cost of the combined procedure, LAAC was superior to OAC under the most circumstances. Scenario analyses demonstrated that the combined procedure was more cost-effective in patients with higher stroke risk. CONCLUSIONS In symptomatic AF patients with high stroke and bleeding risk who are planned for CA, the combined CA and LAAC procedure may be a cost-effective therapeutic option and be more beneficial to patients with CHA2DS2-VASc risk score ≥3.

Abstract
This study aimed to assess the incidence, clinical implications, and treatment strategies of device-related thrombus (DRT) following catheter ablation and percutaneous left atrial appendage occlusion combined in one intervention. A meta-analysis of observational studies was conducted to evaluate the incidence rates, treatment strategies, and clinical implications of DRT. A total of 21 studies describing DRT events and 1 case were included in the current study. The 21 included studies comprised 3 multi-center registries and 18 single-center registries, and we also included 1 case report analyzing the characteristics of DRT. The pooled incidence of DRT in one-stop intervention was 18/1,708 (1.2%; range = 0%-7.3%; 95% CI = 0.7%-1.8%; I 2 = 0). Of these DRT events, 56.25% were diagnosed in the first 3 months after the procedure. All cases were diagnosed via trans-esophagus echocardiogram. All of the patients diagnosed with DRT were prescribed anticoagulation treatment, and 63% (12/19) of the events were reported with an outcome of complete thrombus resolution. The duration of anticoagulation treatment varied greatly, from 30 days to 6 months. Unknown clinical events were reported relating to DRT. Device-related thrombus is an uncommon complication of one-stop intervention. It occurs mainly in the early period following the procedure. Anticoagulation appears to be an appropriate treatment method for dissolving occurrences of DRT.

Abstract
Left atrial appendage occlusion is utilized as a second line therapy to long-term oral anticoagulation in appropriately selected patients with atrial fibrillation (AF). We examined the feasibility of cryoballoon (CB) pulmonary vein isolation (PVI) subsequent to Watchman device implantation. The study prospectively identified patients with Watchman devices (>90 days old) who underwent CB-PVI ablation between 2018 and 2019. Twelve consecutive patients (male 50%; mean age 71 ± 9 years; CHA2DS2-VASc score 3.4 ± 1.1) underwent CB-PVI procedures after Watchman device implantation (mean 182 ± 82 days). Acute PVI was achieved in 100% of patients. All patients had evidence of complete (n = 9) or partial (n = 3) endothelialization of the surface of the Watchman device with conductive tissue properties demonstrated during electrophysiologic testing. There were no major procedure-related complications including death, stroke, pericardial effusion, device dislodgment, device thrombus, or new or increasing peri-device leak. Mean peri-device leak size (45-day postimplant: 0.06 ± 0.09 mm vs Post-PVI: 0.04 ± 0.06 mm; p = 0.61) remained unchanged. Two patients had recurrence of AF after the 90-day blanking period (13.2 ± 6.6 months). One patient underwent a redo ablation procedure for recurrent AF. This pilot study suggests the potential feasibility of CB-PVI ablation in patients with chronic Watchman left atrial appendage occlusion devices. Larger prospective studies are needed to confirm the clinical efficacy and safety of this approach.

Abstract
OBJECTIVE To investigate the effect of the combination of atrial fibrillation (AF) ablation and left atrial appendage closure (LAAC) on cardiac function and the success rate of AF ablation. METHODS We retrospectively analyzed the data of 56 patients with AF undergoing a one-stop procedure for AF ablation and LAAC in our hospital between May, 2015 and May, 2019. Propensity score matching (PSM) at the ratio of 1:1 was used to select 56 control patients undergoing AF ablation at high risk of stroke, for matching with the hybrid procedure group. The perioperative complications, thromboembolic events, recurrence of atrial arrhythmia and cardiac function were compared between the groups. RESULTS The two groups of patients were comparable for age, gender, BMI, duration and type of AF, concomitant diseases, CHA2DS2-VASc and HAS-BLED scores (P > 0.05). The incidence of complications did not differ significantly between the hybrid procedure group and AF ablation group (17.9% vs 12.5%, P=0.430). Compared with the control patients with AF ablation alone, the patients undergoing the hybrid procedure had a lowered incidence of thromboembolic events, but the difference was not statistically significant (1.8%vs 3.6%, P=1.000). The hybrid procedure did not improve the success rate of AF ablation (OR: 1.338, 95%CI: 0.451-3.973, P= 0.600) but significantly improved the cardiac function parameters including NT-pro BNP (945.3±1401.6 pg/mL vs 1520.7±2089.1 pg/mL, P=0.010), LVEF[(60.8±7.0)% vs (58.6±7.8)%, P=0.044], and left atrial diameter (43.9±7.5 mm vs 45.6±6.3 mm, P=0.076); but the improvement of cardiac function was more obvious in the control patients undergoing AF ablation alone (P < 0.039). CONCLUSIONS The combination of AF ablation and LAAC is safe but does not improve the success rate of AF ablation. The one-stop procedure can improve cardiac function of the patients, but AF ablation alone can achieve better improvement of cardiac function.

Abstract
INTRODUCTION Combined catheter ablation (CA) and left atrial appendage closure (LAAC) have proven to be a feasible and safe strategy in treating patients with nonvalvular atrial fibrillation (AF). However, the interactions between CA and LAAC have not been systematically explored. We analyzed the impact of CA on long-term outcomes of LAAC in patients with AF treated with the hybrid procedure. METHODS A total of 107 consecutive patients with AF who underwent LAAC were divided into two groups: group A (n = 61) included patients who underwent CA followed by LAAC during the same procedure and group B (n = 46) included patients who underwent LAAC only. All patients underwent systematic transesophageal echocardiography (TEE) follow-up. RESULTS In group A, CA resulted in severe edema of the left atrial ridge (LAR), which manifested as an increase in LAR thickness from 4.6 ± 0.4 mm before CA to 6.8 ± 0.6 mm (P < .01) after CA. TEE at 45 days showed that the incidence of peri-device leakage was significantly higher in group A than in group B (45.9% vs 4.3%, P < .001). At the 12-month follow-up, the peri-device leakage rate remained higher in group A than in group B (14.8% vs 2.2%, P < .01). Three (4.9%) patients in group A experienced transient ischemia attacks; no events were reported in group B during the 1-year follow-up. CONCLUSION Edema of LAR with the single-stage procedure that consists of CA followed by LAAC could result in increased peri-device leakage and decreased compression rate over time, which may be also associated with elevated risk profiles when compared with an LAAC-only procedure.

Abstract
A 57 year-old patient with dilated cardiomyopathy, long-standing persistent atrial fibrillation, heart failure and episodes of gastrointestinal bleeding underwent AF ablation with pulmonary vein isolation, homogeneization of septal scar, posterior wall isolation and also left atrial appendage isolation. Additionally, because of the high risk of embolism, underwent left atrial appendage occlusion.

Acute left atrial ridge lesion after cryoballoon ablation: How does this affect left atrial appendage closure combined procedure? J Cardiovasc Electrophysiol 2020; 31:2865-2873.

Abstract
BACKGROUND Acute left atrial ridge (LAR) lesions have been observed following atrial fibrillation (AF) ablation. However, LAR lesions had not yet been quantitatively evaluated and their influence on procedure combining cryoballoon (CB) ablation with left atrial appendage closure (LAAC) remained to be explored. METHODS The profile of LAR lesions was measured by transesophageal echocardiography (TEE) in 117 consecutive nonvalvular AF patients, who underwent the combined procedure of CB ablation and LAAC. We thoroughly investigated how LAR lesions correlated with baseline variables and clinical outcomes. RESULTS A total of 95 out of 96 available TEE images presented prominent acute LAR lesions. In terms of dimensions, there was a greater change in width (Δwidth = 3.6 ± 2.3 mm) than the thickness (Δthickness = 2.6 ± 3.5 mm), and the outer ostium was narrowed (Δouter ostium diameter = -3.4 ± 4.0 mm), while the inner ostium remained unchanged. A higher nadir temperature when freezing the left superior pulmonary vein (LSPV) led to an LAR lesion with a two times greater width (adjusted odds ratio = 1.16; 95% confidence interval, 1.02-1.31). In the evaluation of LAAC outcomes, four patients implanted with Watchman devices had minimal residual flow at the inferior border, while two implanted with LAmbre devices developed residual flow at the LAR side. Clinical outcomes were similar between groups divided by lesion size. CONCLUSION Acute LAR lesions frequently occurred following the CB ablation combined procedure, and lesion width positively correlates with LSPV nadir temperature. The presence of these lesions affects the measurement of pacifier devices but has little impact on that of occluder devices.

Abstract
Aim The feasibility and safety of performing the combined procedure of catheter ablation (CA) and left atrial appendage closure (LAAC) for atrial fibrillation (AF) have been reported by observational studies without controls. The aim of this study was to compare the procedural and long-term outcomes of combined procedures with isolated CA or LAAC. Methods and Results This study included patients who underwent combined CA and LAAC (combined group), CA alone (CA-only group), or LAAC alone (LAAC-only group). Propensity score matching was used to select controls from the CA-only and LAAC-only groups. Each group contained 76 subjects. The procedures were successfully performed in all the patients. Procedure-related complications of the combined group included one pericardial effusion and two groin haematomas, which did not differ significantly with those of the CA-only group (3.9% vs. 2.6%, P=0.650) or the LAAC-only group (3.9% vs. 2.6%, P=0.650), respectively. The AF-free rate of the combined group was comparable with that of the CA-only group after a mean of 2 years follow-up (67.1% vs. 69.7%, P=0.727). Compared with the LAAC-only group, the combined group achieved similar complete occlusion rate at implant (94.7% vs. 93.4%) and at 45 days (82.9% vs. 85.5%). At the end of follow-up, ischemic stroke and bleeding events of the combined group were low (3.9%) and were comparable with those of the CA-only group (5.3%) and the LAAC-only group (2.6%). Conclusions The combination of AF-CA and LAAC is safe and efficacious compared with single procedures alone.

JACC Clin Electrophysiol 2020; 6:494-506. [PMID: 32439033 PMCID: PMC7988890 DOI: 10.1016/j.jacep.2019.11.009] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Revised: 11/07/2019] [Accepted: 11/14/2019] [Indexed: 02/08/2023]
Abstract
OBJECTIVES The aim of this study was to compare bleeding, thromboembolic, device-related thrombus (DRT), and all-cause mortality events between patients treated with short-term oral anticoagulation (OAC) and those treated with short-term antiplatelet therapy (APT) following left atrial appendage occlusion (LAAO). BACKGROUND Short-term OAC is recommended for patients following LAAO. However, in practice many patients receive APT rather than OAC because of excessive bleeding risk. However, the safety and efficacy of APT compared with OAC have been debated. METHODS A search was conducted of databases for studies comparing OAC with APT following LAAO. The outcomes of interest were all-cause stroke, major bleeding, DRT, and all-cause mortality. Noncomparative studies were pooled into a single study to generate comparisons of the studies' outcomes. Effects measure were pooled using the random-effect model. RESULTS A total of 83 studies with 12,326 patients (APT, n = 7,900; OAC, n = 4,151) were included. Mean CHA2DS2-VASc and HAS-BLED scores were 4.1 ± 1.6 and 3.0 ± 1.3, respectively. There were no significance differences between the APT and OAC groups with regard to stroke (risk ratio [RR]: 1.04; 95% confidence interval [CI]: 0.54 to 1.98; p = 0.91; I2 = 31%), major bleeding (RR: 1.12; 95% CI: 0.68 to 1.84; p = 0.65; I2 = 53%), DRT (RR: 1.33; 95% CI: 0.74 to 2.39; p = 0.33; I2 = 36%), and all-cause mortality (RR: 1.29; 95% CI: 0.40 to 4.09; p = 0.18; I2 = 36%). These findings persisted in multiple secondary analyses: 1) excluding studies that reported no events; 2) including comparative studies only; 3) excluding patients who were treated with single APT; and 4) removing one study at a time to assess the effect of each study on the overall effect size. There was also no difference in the studies' endpoints among patients who received different LAAO devices. CONCLUSIONS In a meta-analysis of observational data, there were no differences in the occurrence of stroke, major bleeding DRT, and all-cause mortality in patients treated with short-term OAC or APT following LAAO.

Abstract
Left atrial appendage (LAA) mechanical exclusion is being investigated for nonpharmacologic stroke risk reduction in selected patients with atrial fibrillation. There are multiple potential approaches in various stages of development and clinical application, each of which depends on specific cardiothoracic anatomic characteristics for optimal performance. Multiple imaging modalities can be utilized for application of this technology, with transesophageal echocardiography used for intraprocedural guidance. Cardiovascular computed tomographic angiography can act as a virtual patient avatar, allowing for the assessment of cardiac structures in the context of surrounding cardiac, coronary vascular, thoracic vascular, and visceral and skeletal anatomy, aiding preprocedural decision-making, planning, and follow-up. Although transesophageal echocardiography is used for intraprocedural guidance, computed tomographic angiography may be a useful adjunct for preprocedure assessment of LAA sizing and anatomic obstacles or contraindications to deployment, aiding in the assessment of optimal approaches. Potential approaches to LAA exclusion include endovascular occlusion, epicardial ligation, primary minimally invasive intercostal thoracotomy with thoracoscopic LAA ligation or appendectomy, and minimally invasive or open closure as part of cardiothoracic surgery for other indications. The goals of these procedures are complete isolation or exclusion of the entire appendage without leaving a residual appendage stump or residual flow with avoidance of acute or chronic damage to surrounding cardiovascular structures. The cardiovascular imager plays an important role in the preprocedural and postprocedural assessment of the patient undergoing LAA exclusion.

Efficacy and safety of catheter ablation combined with left atrial appendage occlusion for nonvalvular atrial fibrillation: A systematic review and meta-analysis. Pacing Clin Electrophysiol 2019; 43:123-132. [PMID: 31721242 DOI: 10.1111/pace.13845] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2019] [Revised: 10/31/2019] [Accepted: 11/11/2019] [Indexed: 02/05/2023]
Abstract
Atrial fibrillation (AF) is currently the most prevalent arrhythmia in clinical practice, with stroke being one of its major complications. Combining catheter ablation and percutaneous left atrial appendage occlusion (LAAO) into a "one-stop" intervention could reduce stroke incidence in selected high-risk patients and, at the same time, relieve AF symptoms in a single procedure. This meta-analysis analyzed the efficacy and safety of catheter ablation combined with LAAO for nonvalvular AF. PubMed, EMBASE, and the Cochrane Library were searched from inception to April 2019 to identify relevant citations. Efficacy indexes were procedural success, AF recurrence, stroke/transient ischemic attacks (TIA), and device-related thrombus (DRT). Safety indexes were all-cause death, major hemorrhagic complications, and pericardial effusion/cardiac tamponade. The incidence rate of events (ratio of events to patients) and 95% confidence interval (CI) were calculated as summary results. A forest plot was constructed to present pooled rates. Eighteen studies (two randomized controlled trials and 16 observational studies) were included. The results showed that one-stop intervention has significant efficacy and safety, with procedural success of .98 (95% CI, .97-1.00), AF recurrence of .24 (95% CI, .15-.35), stroke/TIA of .01 (95% CI, .00-.01), DRT of .00 (95% CI, .00-.01), all-cause mortality of .00 (95% CI, .00-.00), cardiac/neurological mortality of .00 (95% CI, .00-.00), major hemorrhagic complications of .01 (95% CI, .00-.02), and pericardial effusion/cardiac tamponade of .01 (95% CI, .00-.01). A single procedure with catheter ablation and LAAO in AF is a feasible strategy with significant efficacy and safety.

Abstract
Aims Long-term freedom from atrial fibrillation (AF) after catheter ablation (CA) and consequently the potential for stroke reduction remain unpredictable. Percutaneous left atrial appendage closure (LAAC) is an effective mechanical alternative to oral anticoagulation (OAC) for stroke prevention in AF patients. This study aims to evaluate long-term clinical results of combined CA and LAAC in one single procedure. Methods and results Patients with non-valvular AF who underwent combined CA and LAAC procedure were included in the retrospective compilation of independent prospective general LAAC registries at the individual centres. Transoesophageal echocardiography (TOE) was used to evaluate device position and LAA sealing. Between 2009 and 2015, 349 patients with AF (58% male, age 63.1 ± 8.2 years; score for stroke prediction in AF patients (CHA2DS2-VASc) 3.0; score for major bleeding in patients on anticoagulation (HAS-BLED) 3.0; 56% paroxysmal AF) were included. Indications for LAAC included previous stroke (38%), history of bleeding (22%), and physician/patient preference (29%). Periprocedural complications up to 30 days included pericardial effusion (1.5%) and one minor stroke (0.3%) but no death. After 6 weeks, TOE showed successful sealing of the LAA in 98.9%. After 35 months of follow-up, 51% of patients had AF recurrence. A total of nine ischaemic strokes were recorded, resulting in an annualized stroke rate of 0.9% compared to an expected stroke rate of 3.2% without anticoagulation and combined treatment. Conclusion This large pooled multicentre analysis of five prospective registries shows that combining CA and LAAC is feasible, safe, and successful. Long-term follow-up shows greatly reduced stroke and bleeding rates despite recurrence of AF in more than half of the patients.

Abstract
Background Catheter ablation (CA) and left atrial appendage closure (LAAC) have been combined into a novel one-stop procedure for patients with atrial fibrillation (AF). However, postoperative complications are relatively common in patients undergoing LAAC; the complications, including residual flow, increase in the risk of bleeding, or other adverse events, are unknown in patients receiving one-stop therapy. Therefore, we tried to evaluate the adverse events of CA and LAAC hybrid therapy in patients with nonvalvular AF. Methods We performed a meta-analysis and computer-based literature search to identify publications listed in the PubMed, Embase, and Cochrane library databases. Studies were included if patients received CA and LAAC hybrid therapy and reported adverse events. Results Overall 13 studies involving 952 patients were eligible based on the inclusion criteria. In the periprocedural period, the pooled incidence of pericardial effusion was 3.15%. The rates of bleeding events and residual flow were 5.02 and 9.11%, respectively. During follow-up, the rates of all-cause mortality, embolism events, bleeding events, AF recurrence, and residual flow were 2.15, 5.24, 6.95, 32.89, and 15.35%, respectively. The maximum occurrence probability of residual flow events was 21.87%. Bleeding events were more common in patients with a higher procedural residual flow event rate (P = 0.03). A higher AF recurrence rate indicated higher rates of embolism events (P = 0.04) and residual flow (P = 0.03) during follow-up. Conclusions Bleeding events were more common in patients with a higher procedural residual flow event rate. However, combined CA and LAAC therapy is reasonably safe and efficacious in patients with nonvalvular AF. Further studies on the safety and efficacy of CA or LAAC alone are necessary in future.

Abstract
BACKGROUND AND OBJECTIVE Atrial fibrillation (AF) represents the most common cardiac arrhythmia worldwide; it poses a great burden in terms of quality of life reduction and yearly stroke risk. Left atrial appendage closure (LAAC) is a stroke prevention strategy that has been proven a viable alternative to antithrombotic regimens in nonvalvular AF patients. LAAC can be performed as a standalone procedure or alongside a concomitant AF transcatheter ablation, in a procedure known as "Combined procedure". Aim of this study is to summarize the scientific evidence backing this combined strategy. METHODS We reviewed the whole Medline indexed combined procedure literature, to summarize all the combined procedure study data. RESULTS Nine published studies regarding combined procedure were found. Data, aims, and scientific rationales were reported and commented. CONCLUSION LAA combined procedure appears to be a safe and effective procedure; a careful patient selection is necessary to maximize its benefit.

Abstract
BACKGROUND The combined left atrial appendage closure (LAAC) and cryoenergy pulmonary vein isolation (PVI) procedure has been proven safe and effective in managing stroke in patients with nonvalvular atrial fibrillation (AF), although most data refer to procedures performed using radiofrequency as the main energy source. OBJECTIVE The purpose of this study was to evaluate long-term follow-up of patients with AF undergoing concomitant LAAC and cryoenergy PVI. METHODS Patients undergoing LAAC and cryoballoon PVI at our institution were enrolled. At 3, 6, and 24 months from the index procedure, we determined the atrial arrhythmia recurrence rate, the extent of LAAC, and the rate of cerebrovascular/bleeding events. RESULTS Forty-nine patients (mean age 69 ± 8 years; 32/49 (67%) men; CHA2DS2-VASc score 2.8 ± 1.2; HAS-BLED score 3 ± 1) with a guideline-recommended LAAC indication were included. Acute PVI and complete LAAC were achieved in 100% of patients. All patients completed at least 24 months of follow-up. At 8 weeks and 6 months, complete or satisfactory (<5 mm leak) LAAC rates were achieved in 40 (82%) and 9 (18%) and in 42 (86%) and 7 (14%) of patients, respectively. The overall freedom from atrial arrhythmia rate at 24 months was 29 (60%), and 45 (92%) of patients were off antithrombotic drugs. The observed annualized stroke and bleeding rates were 1% and 2%, respectively, a 71% and 60% risk reduction in comparison to event rates predicted from CHA2DS2-VASc and HAS-BLED scores. CONCLUSION Concomitant cryoballoon ablation and LAAC procedures appear safe and effective at long-term follow-up, with high antithrombotic drug withdrawal rates at 24 months.

Abstract
AIMS This study aimed to assess the safety and efficacy at midterm follow-up of left atrial appendage occlusion (LAAO) using different devices, in real life in Belgium. METHODS AND RESULTS Between June 2009 and November 2016, 457 consecutive patients (63% male, 75±12 yrs, CHA2DS2-VASc 4±0.6, HAS-BLED 3.5±0.7) undergoing LAAO were included. Technical success was 97.1%. There were 19 periprocedural major adverse events (4.1%) including three deaths (0.6%), nine tamponades (1.9%), four major bleedings (0.8%) and two device embolisations (0.4%). Among patients successfully implanted having a complete follow-up (672 patient-years, median follow-up 370 days), the actual annual stroke rate was 1.2%, lower than the expected stroke risk of 4% (70% reduction). The observed bleeding rate was 2%, while the calculated risk was 3.7% (46% reduction). Kaplan-Meier analysis showed a similar overall survival (93±2% and 87±3% versus 91±3% and 87±4%; p=0.35) and event-free survival (92±2% and 84±3% versus 88±3% and 80±5%; p=0.17) at one and two years, for the ACP/Amulet versus the WATCHMAN groups of patients, respectively. CONCLUSIONS The data from the Belgian left atrial appendage occlusion registry suggest that the procedure is effective and relatively safe in a real-world setting, using either the WATCHMAN or the ACP/Amulet device.

Abstract
Aims Long-term results from catheter ablation therapy for atrial fibrillation (AF) remain uncertain and clinical practice guidelines recommend continuation of long-term oral anticoagulation in patients with a high stroke risk. Left atrial appendage closure (LAAC) with Watchman has emerged as an alternative to long-term anticoagulation for patients accepting of the procedural risks. We report on the initial results of combining catheter ablation procedures for AF and LAAC in a multicentre registry. Methods and results Data were pooled from two prospective, real-world Watchman LAAC registries running in parallel in Europe/Middle-East/Russia (EWOLUTION) and Asia/Australia (WASP) between 2013 and 2015. Of the 1140 patients, 139 subjects at 10 centres underwent a concomitant AF ablation and LAAC procedure. The mean CHA2DS2-VASc score was 3.4 ± 1.4 and HAS-BLED score 1.5 ± 0.9. Successful Watchman implantation was achieved in 100% of patients. The overall 30-day serious adverse event (SAE) rate was 8.7%, with the device and/or procedure-related SAE rate of 1.4%. One pericardial effusion required percutaneous drainage, but there were no strokes, device embolization, or deaths at 30 days. The 30-day bleeding SAE rate was 2.9% with 55% of patients prescribed NOAC and 38% taking warfarin post-procedure. Conclusion The outcomes from these international, multicentre registries support the feasibility and safety of performing combined procedures of ablation and Watchman LAAC for patients with non-valvular AF and high stroke risk. Further data are needed on long-term outcomes for the hybrid technique on all-cause stroke and mortality.

Abstract
BACKGROUND/PURPOSE Experience in procedures combining left atrial appendage (LAA) closure (LAAC) and catheter ablation (CA) was scarce in Chinese nonvalvular atrial fibrillation (AF) patients with high risks for stroke and bleeding. We aimed to investigate the efficacy and safety of the combination therapy with LAAC and AF CA in a single procedure based on the multicenter data and medium-term follow-up results. METHODS A total of 122 AF patients with a mean CHA2DS2-VASc score of 4.3 ± 1.4 and HAS-BLED score of 3.3 ± 1.0 were enrolled. The Watchman (n = 83) devices were implanted either before or after AF ablations in the same procedure, while the Amplatzer Cardiac Plug (ACP, n = 39) devices were implanted immediately after CA. AF recurrence and transesophageal echocardiography results were evaluated. RESULTS All devices were successfully implanted and acute complete LAA occlusions were achieved in 115 (94.3%) of patients. Neither acute nor chronic peri-device leaks greater than 5 mm were detected. Oral anticoagulation was held in all patients but two with asymptomatic device-related thrombi, which were resolved after prolonged anticoagulation. AF-free success rate without antiarrhythmic drugs was 76.2% after a mean follow-up of 11.5 ± 6.8 months. No serious complications were observed during the follow-up. CONCLUSION The combination therapy with LAAC and AF ablation in a single procedure was efficacious and safe in the Chinese symptomatic AF population with high risk for stroke and bleeding.

Abstract
Patients with atrial fibrillation (AF) have an increased risk of stroke and systemic embolism. Catheter ablation (CA) is increasingly applied for the treatment for drug-refractory AF; however, its long-term success rate is <50%. It has been proved that percutaneous left atrial appendage occlusion (LAAO) exerts the same efficacy as novel oral anti-coagulants [(N)OACs] in reducing thromboembolic events. The present study investigated whether a combined procedure of AF ablation and LAAO may be feasible and efficacious. CA was performed for patients with AF and a high risk of stroke according to their CHADS2 or CHA2DS2-VASc score, and LAAO was performed using the Watchman device. A total of 25 patients (40% females; mean age, 64.2±3.5 years) who were treated between July 2016 and June 2017 were included in the present study. The median CHA2DS2-VASc score was 4.5 (range, 2-6) and the median HAS-BLED score was 3.17 (range, 1-7). Successful CA and LAAO were performed in 100% of cases. All patients met the criteria for successful LAAO. At the 6-month follow-up, complete sealing of the LAA was achieved in 23 patients (92%), while a minimal residual flow (<5 mm) was detected in 2 patients (8%). In 24 patients (96%), the administration of (N)OACs was terminated and aspirin administration was initiated at the 6-month follow-up. (N)OAC treatment was maintained in 1 patient (4%) on the basis of transient ischemic attack. During the 6-month follow-up period, 3 patients who had a recurrence of AF received a repeated ablation. In conclusion, the combination of CA and LAAO in a single procedure is feasible, safe and efficacious for patients with non-valvular AF at a high risk of stroke, and a contraindication regarding the use of (N)OACs.

Optimal combination strategy of left atrial appendage closure plus catheter ablation in a single procedure in patients with nonvalvular atrial fibrillation.

Abstract
BACKGROUND The efficacy and safety of combining left atrial appendage closure (LAAC) plus atrial fibrillation (AF) catheter ablation (CA) in a single procedure has been established, but the optimal combination strategy has not been thoroughly elucidated to date. OBJECTIVE We aimed to investigate the impact of different combination strategies on clinical outcomes. METHODS Eighty-two consecutive patients with symptomatic AF (mean CHA2 DS2 -VASc score 4.4 ± 1.4, mean HAS-BLED score 3.5 ± 1.0) were enrolled. LAAC with the Watchman device was performed either before (occlusion-first group, N = 52) or after (ablation-first group, N = 30) CA. Procedural and clinical data were retrospectively analyzed to evaluate the advantages of each strategy. RESULTS Complete device occlusions were achieved in 92.3% and 90.0% of patients, respectively (P = 0.719). Neither acute nor chronic peridevice leak greater than 5 mm was detected. Oral anticoagulants were held in all patients, except two (one in each group) with asymptomatic device-related thrombi. AF-free success rates were comparable between groups with a mean follow-up of 11.2 ± 7.3 months (75.0% vs. 70.0%, log-rank P = 0.311). The new peridevice leak rate was significantly lower in the occlusion-first group (7.7% vs. 26.7%, P = 0.019). Multivariate logistic regression demonstrated that the combination strategy was independently associated with the new peridevice leak (P = 0.025, OR 13.3). CONCLUSIONS Both occlusion-first and ablation-first strategies were efficacious and safe as combined procedures in patients with nonvalvular AF; however, the occlusion-first strategy was associated with lower new peridevice leak rates at follow-up.

Abstract
INTRODUCTION Atrial fibrillation (AF) is the most common cardiac arrhythmia. The incidence of AF increases with age and is associated with increased stroke, heart failure and mortality. Persistent and long standing persistent AF is difficult to treat and often refractory to medical therapy and catheter ablation. Areas covered: This article reviews the historical development of the surgical Cox-MAZE procedure and current hybrid and minimally invasive surgical approaches for the treatment of persistent and long standing persistent AF. The role of concomitant pulmonary vein isolation and left atrial appendage (LAA) exclusion will also be reviewed. Expert commentary: An ablation pattern emulating the Cox-Maze surgical procedure is commonly needed to obtain maintenance of sinus rhythm in patients with persistent and long standing persistent atrial fibrillation. Minimally invasive bilateral thorascopic surgical procedures can achieve a similar Cox-Maze lesion set, but are associated with increased adverse events compared to catheter ablation. Future prospective randomized studies are required to confirm whether the recently developed hybrid subxyphoid epicardial/endocardial procedure and percutaneous LAA ligation and catheter ablation are indeed as effective as surgical options with less adverse events.
