Abstract
BACKGROUND Left atrial appendage closure (LAAC) is a treatment modality for stroke prevention in patients with atrial fibrillation (AF). One of the potential complications of LAAC is a peri-device leak (PDL), which could potentially increase the risk of thromboembolism formation. METHODS This systematic review was done according to PRISMA guidelines. Using four databases, all primary studies through April 2022 that met selection criteria were included. Outcomes of interest were studies reporting on PDL characteristics, risk factors and management. RESULTS A total of 116 studies met selection criteria (97 original studies and 19 case reports/series). In the original studies (n = 30,133 patients), the weighted mean age was 72.0 ± 7.4 years (57% females) with a HAS-BLED and CHA2DS2-VASc weighted means of 2.8 ± 1.1 and 3.8 ± 1.3, respectively. The most common definition of PDL was based on size; 5 mm: major, 3-5 mm: moderate, < 1 mm minor, or trivial. Follow up time for PDL detection was 7.15 ± 9.0 months. 33% had PDL, irrespective of PDL severity/size, and only 0.9% had PDL of greater than 5 mm. The main risk factors for PDL development included lower degree of over-sizing, lower left ventricular ejection fraction, device/LAA shape mismatch, previous radiofrequency ablation, and male sex. The most common methods to screen for PDL included transesophageal echocardiogram and cardiac CT. PDL Management approaches include Amplatzer Patent Foramen Ovale occluder, Hookless ACP, Amplatzer vascular plug II, embolic coils, and detachable vascular coils; removal or replacement of the device; and left atriotomy. CONCLUSION Following LAAC, the emergence of a PDL is a significant complication to be aware of. Current evidence suggests possible risk factors that are worth assessing in-depth. Additional research is required to assess suitable candidates, timing, and strategies to managing patients with PDL.

Abstract
BACKGROUND New and refined catheter based left atrial appendage (LAA) closure devices have been introduced in the past decade. The procedure can be performed using either an endocardial occlusion device or an epicardial loop stitch. We aimed to analyzed recent procedural safety. METHODS Catheter based LAA closures were identified in a complete nationwide German dataset via ICD and OPS codes from 2016 to 2020. RESULTS From 2016 to 2020, 28,039 endocardial and 213 epicardial occlusions were performed. Numbers of endocardial procedures increased from 5259 in 2016 to 5917 in 2020 (p = 0.020) in 387 centers with shifting of patients' characteristics towards older age (β = 0.29, p < 0.001), more heart failure (β = 1.01, p < 0.001) and renal disease (β = 0.67, p = 0.001) and without a significant trend for in-hospital safety except more bleeding (β = 0.12, p = 0.05). In-hospital major adverse cardiac and cerebrovascular events (MACCE) or pericardial puncture were independent on center procedure numbers. The loop stitch procedure was performed in 15 centers. Patients were younger (76.17 ± 8.16 vs. 73.16 ± 8.99, p < 0.001) and had a lower comorbidity index (2.29 ± 1.93 vs. 1.92 ± 1.64, p = 0.005). Adjusted risk difference for pericardial effusion (8.04%; 95% CI 3.01-13.08%; p = 0.002) and pericardial puncture (6.60%; 95% CI 3.85-9.35%; p < 0.001) was higher for the loop stitch procedure, while risk of bleeding (- 1.85%; 95% CI - 3.01 to - 0.69%; p = 0.002), intracerebral bleeding (- 0.37%; 95% CI - 0.59 to - 0.15%; p = 0.001) and shock (- 1.41%; 95% CI - 2.44 to - 0.39%; p = 0.007) was lower. No significant difference was observed for in-hospital MACCE. CONCLUSIONS Endocardial occlusion was the major catheter based LAA closure procedure in Germany without improvements in in-hospital safety from 2016 to 2020. In-hospital MACCE was independent on endocardial LAAC center volumes. Conclusions on the comparison between the two procedure types must be made cautious as the LAA loop stitch occlusion was utilized limited in a minor number of centers.

Abstract
Left atrial appendage (LAA) epicardial exclusion has been associated with addressing 2 potential deleterious consequences attributed to the LAA, namely, thrombus formation and an arrhythmogenic contributor in advanced forms of atrial fibrillation. With more than 60 years of history, the surgical exclusion of the LAA has been firmly established. Numerous approaches have been used for surgical LAA exclusion including surgical resections, suture ligation, cutting and non-cutting staples, and surgical clips. Additionally, a percutaneous epicardial LAA ligation approach has been developed. A discussion of the various epicardial LAA exclusion approaches and their efficacy will be discussed, along with the salient beneficial affects on LAA thrombus formation, LAA electrical isolation and neuroendocrine homeostasis.

Abstract
Intracranial hemorrhage (ICH) is considered a potentially severe complication of oral anticoagulants (OACs) and antiplatelet therapy (APT). Patients with atrial fibrillation (AF) who survived ICH present both an increased ischemic and bleeding risk. Due to its lethality, initiating or reinitiating OACs in ICH survivors with AF is challenging. Since ICH recurrence may be life-threatening, patients who experience an ICH are often not treated with OACs, and thus remain at a higher risk of thromboembolic events. It is worthy of mention that subjects with a recent ICH and AF have been scarcely enrolled in randomized controlled trials (RCTs) on ischemic stroke risk management in AF. Nevertheless, in observational studies, stroke incidence and mortality of patients with AF who survived ICH had been shown to be significantly reduced among those treated with OACs. However, the risk of hemorrhagic events, including recurrent ICH, was not necessarily increased, especially in patients with post-traumatic ICH. The optimal timing of anticoagulation initiation or restarting after an ICH in AF patients is also largely debated. Finally, the left atrial appendage occlusion option should be evaluated in AF patients with a very high risk of recurrent ICH. Overall, an interdisciplinary unit consisting of cardiologists, neurologists, neuroradiologists, neurosurgeons, patients, and their families should be involved in management decisions. According to available evidence, this review outlines the most appropriate anticoagulation strategies after an ICH that should be adopted to treat this neglected subset of patients.

Abstract
Percutaneous epicardial ventricular tachycardia ablation can decrease implanted cardioverter defibrillator shocks and hospitalizations; proper patient selection and procedural technique are imperative to maximize the benefit-risk ratio. The best candidates for epicardial ventricular tachycardia will depend on history of prior ablation, type of cardiomyopathy, and specific electrocardiogram and cardiac imaging findings. Complications include hemopericardium, hemoperitoneum, coronary vessel injury, and phrenic nerve injury. Modern epicardial mapping techniques provide new understandings of the 3-dimensional nature of reentrant ventricular tachycardia circuits across cardiomyopathy etiologies. Where epicardial access is not feasible, alternative techniques to reach epicardial ventricular tachycardia sources may be necessary.

Abstract
Atrial fibrillation (AF), the most common sustained arrhythmia in clinical practice, represents a major cause of morbidity and mortality, with an increasing prevalence. Pharmacologic treatment remains the cornerstone of its management through rhythm and rate control, as well as the prevention of thromboembolism with the use of oral anticoagulants. Recent progress in percutaneous interventional approaches have provided additional options in the therapeutic arsenal, however. The use of the different catheter ablation techniques can now lead to long arrhythmia-free intervals and significantly lower AF burden, thus reducing the rate of its complications. Particularly encouraging evidence is now available for patients with persistent AF or concomitant heart failure, situations in which catheter ablation could even be a first-line option. In the field of stroke prevention, targeting the left atrial appendage with percutaneous device implantation may reduce the risk of thromboembolism to lower rates than that predicted with conventional ischemic risk scores. Left atrial appendage occlusion through the approved Watchman or Amplatzer devices is a well-established, efficacious, and safe method, especially in high-ischemic and bleeding risk patients with contraindications for oral anticoagulation.

Abstract
Although oral anticoagulants (OACs) are first-line therapy for stroke prevention in patients with atrial fibrillation (AF), some patients cannot be treated with OACs due to absolute or relative contraindications. Left atrial appendage (LAA) exclusion techniques have been developed over the years as a therapeutic alternative for stroke prevention. In this paper, we review the evolution of surgical techniques, employed as an adjunct to cardiac surgery or as a stand-alone procedure, as well as the recently introduced and widely utilized percutaneous LAA occlusion techniques. Until recently, data on surgical LAAO were limited and based on non-randomized studies. We focus on recently published randomized data which strongly support an add-on surgical LAAO in eligible patients during cardiac surgery and could potentially change current practice guidelines. In recent years, the trans-catheter techniques for LAA occlusion have emerged as another, less invasive alternative for patients who cannot tolerate oral anticoagulation. We review the growing body of evidence from prospective studies and registries, focusing on the two systems which are in widespread clinical use nowadays: the Watchman and Amulet type devices. These data show favorable results for both Watchman and Amulet devices, setting them as an important tool in our arsenal for stroke reduction in AF patients, especially in those who have contraindications for OACs. A better understanding of the different therapeutic alternatives, their specific benefits, and downfalls in different patient populations can guide us in tailoring the optimal therapeutic approach for stroke reduction in our AF patients.

Abstract
It has been shown that endocardial occlusion of the left atrial appendage (LAA) is equally effective in preventing embolic events compared to oral anticoagulation in patients with non-valvular atrial fibrillation An 82-year old female patient was admitted for LAA occlusion for repetitive GI bleeding. She had high CHADSVASC Score and HASBLED with long persistent atrial fibrillation with many comorbities. The preprocedural transesophageal echo revealed a great mass in the left atrium. (picture 1). Cardiac surgery was denied, we performed an epicardial only ligation for closing the LAA. For this approach we performed an epicardial puncture and contrast injection within the pericardial space to delineate the LAA. An epicardial wire with a suction mechanism at its distal end was attached to the anterior lobe of the left atrial appendage. Using this epicardial wire the snare could be advanced over the appendage and closed down. Complete exclusion of the LAA was achieved. There were no procedural complications and the patient is doing well after 3 month. This article is protected by copyright. All rights reserved.

Abstract
Advancements in clinical management, pharmacological therapy and interventional procedures have strongly improved the survival rate for cardiovascular diseases (CVDs). Nevertheless, the patients affected by CVDs are more often elderly and present several comorbidities such as atrial fibrillation, valvular heart disease, heart failure, and chronic coronary syndrome. Standard treatments are frequently not available for “frail patients”, in particular due to high surgical risk or drug interaction. In the past decades, novel less-invasive procedures such as transcatheter aortic valve implantation (TAVI), MitraClip or left atrial appendage occlusion have been proposed to treat CVD patients who are not candidates for standard procedures. These procedures have been confirmed to be effective and safe compared to conventional surgery, and symptomatic thromboembolic stroke represents a rare complication. However, while the peri-procedural risk of symptomatic stroke is low, several studies highlight the presence of a high number of silent ischemic brain lesions occurring mainly in areas with a low clinical impact. The silent brain damage could cause neuropsychological deficits or worse, a preexisting dementia, suggesting the need to systematically evaluate the impact of these procedures on neurological function.

Abstract
Catheter-based left atrial appendage closure (LAAC) is currently a potential treatment option for stroke prevention in patients with atrial fibrillation and high risk for stroke/embolism as well as high bleeding risk. Due to improvements in LAAC devices, advances in implantation techniques and growing experience of the interventional teams, the safety profile of LAAC has significantly improved in recent years. These developments have led to a currently comprehensive exploration of novel indications for LAAC, such as patients with atrial fibrillation and a low risk of hemorrhage, patients with atrial fibrillation after pulmonary vein ablation or patients after electrical isolation of the left atrial appendage. The treatment principle of closure of the left atrial appendage is supported by new data, which show the effectiveness of surgical closure of the left atrial appendage with respect to a reduction of the risk of stroke, at least partly in conjunction with oral anticoagulation during cardiological surgical interventions. Currently, the application in the clinical practice is reflected by a high degree of active studies. These randomized studies are testing the use of LAAC in new fields of application and together with the new developments in implantation techniques should define the optimal future use of the methods for the clinical practice. The current potential indications for the LAAC procedure, ongoing randomized clinical trials and advances in device development, implantation planning and technique as well as future developments in the field of LAAC treatment are summarized and discussed in this review article.

Abstract
The thromboembolic complications of Atrial fibrillation (AF) remain a major problem in contemporary clinical practice. Despite advances and developments in anticoagulation strategies, therapy is complicated by the high risk of bleeding complications and need for meticulous medication compliance. Over the past few decades, the left atrial appendage has emerged as a promising therapeutic target to prevent thromboembolic events while mitigating bleeding complications and compliance issues. Emerging data indicates that it is a safe, effective and feasible alternative to systemic anticoagulation in patients with non-valvular AF. A number of devices have been developed for endocardial or epicardial based isolation of the left atrial appendage. Increasing experience has improved overall procedural safety and ease while simultaneously reducing device related complication rates. Furthermore, increasing recognition of the non-mechanical advantages of this procedure has led to further interest in its utility for further indications beyond the prevention of thromboembolic complications. In this review, we present a comprehensive overview of the evolution of left atrial appendage occlusion, commercially available devices and the role of this modality in the current management of AF. We also provide a brief outline of the landmark trials supporting this approach as well as the ongoing research and future prospects of left atrial appendage occlusion.

Abstract
OBJECTIVE To assess the safety and efficacy of a novel immunosuppressive regimen-combination Methotrexate/Prednisone (cMtx/P)-in the management of severe refractory rPPP. METHODS In this multicenter, nonrandomized, retrospective, observational study, 408 consecutive patients diagnosed with persistent rPPP between 2017 and 19 were included. Patients with refractory symptoms despite 3 months of conventional therapy were initiated on a 4-week regimen of oral steroids. Persistence of symptoms at this point, that is, rPPP (n = 25; catheter based = 18, open surgical = 7) prompted therapy with Methotrexate (7.5-15 mg weekly) with folate supplementation along with low dose prednisone (5 mg PO) for a further 3 months. Patients were followed for a total of 11.3 ± 1.8 months. RESULTS Treatment refractory rPPP occurred in 6.1% of the study population prompting immunosuppressive therapy with cMtx/P. All patients demonstrated complete symptom resolution following 3 months of treatment with an 85% decline in clinically significant pericardial effusions. One patient developed recurrent pericarditis during the 11-month follow-up. Therapy was well tolerated with no significant drug related adverse effects. CONCLUSION cMtx/P therapy is a safe and effective adjunct in the management of rPPP refractory to standard therapy.

Abstract
Transcatheter left atrial appendage (LAA) closure is an alternative to long-term anticoagulation therapy in selected patients with nonvalvular atrial fibrillation who have an increased risk for stroke. LAA closure devices can be implanted by means of either an endocardial or a combined endocardial and epicardial approach. Preprocedural imaging is key to identifying contraindications, accurately sizing the device, and minimizing complications. Transesophageal echocardiography (TEE) has been the reference standard imaging modality to assess the anatomy for LAA closure and to provide intraprocedural guidance. However, CT has emerged as a less-invasive alternative to TEE for pre- and postprocedural imaging. CT is comparable to TEE for exclusion of thrombus but is superior to TEE for the delineation of complex LAA anatomy, measurement for device sizing, and evaluation of pulmonary venous and extracardiac structures. CT provides accurate measurements of the LAA ostial diameter, landing zone diameter, and LAA length, which are vital for accurate sizing of the device. CT allows evaluation of the relationship with the pulmonary veins and other adjacent structures that can be injured during the procedure. CT also simulates procedural fluoroscopic angles and provides evaluation of the interatrial septum, which is punctured during LAA closure. CT also provides a more convenient method for the evaluation of postprocedural complications such as incomplete closure, peridevice leaking, device-related thrombus, and device dislodgement.

Abstract
As procedures such as epicardial ventricular ablation and left atrial appendage occlusion become more commonplace, the need grows for safer techniques to access the physiologic pericardial space. Because this space contains minimal fluid for lubrication, prevailing methods of pericardial access pose considerable periprocedural risk to cardiac structures. Therefore, we devised a novel method of pericardial access in which carbon dioxide (CO2) is insufflated through a right atrial puncture under fluoroscopic guidance, enabling clear visualization of the cardiac silhouette separating from the chest wall. We performed the procedure in 8 Landrace pigs, after which transthoracic percutaneous pericardial access was obtained by conventional means. All of the animals remained hemodynamically stable during the procedure, and none showed evidence of epicardial or coronary injury. The protective layer of CO2 in the pericardial space anterior to the heart facilitated percutaneous access in our porcine model, and the absence of complications supports the potential safety of this method.

Abstract
Introduction We present initial results of patients undergoing a combined procedure of epicardial LAA ligation in addition to left atrial ablation for AF. Methods 9 patients were included for additional use of LARIAT as an individual treatment approach for AF. First an epicardial LAA ligation was performed, in the same procedure left atrial ablations consisting of PVI and additional substrate based modifying ablations were performed. Follow–up at 3 months and 12 months was performed. Results There was only 1 minor procedural complication (11%) involving epicardial bleeding and 2 late adverse events of pericardial tamponade and stroke. At the final follow-up (median 20 months) 7 patients were in stable sinus rhythm (78%) and 2 pts had reduced AF burden. Conclusion Concomitant epicardial LAA ligation and ablation is feasible in selected patients with a reasonable risk profile. More prospective data are required to validate the safety and efficacy.

Abstract
Atrial fibrillation is a common cardiac arrhythmia that carries a risk of stroke. This is commonly stratified with the CHA2DS2-VASc score. Stroke risk can be reduced with anticoagulants or with interventions to close the left atrial appendage, the most common source of left atrial thrombi. While warfarin has been traditionally used as the only oral anticoagulant available, there are several direct oral anticoagulants that compare favorably with respect to both stroke and bleeding risk in randomized controlled trials. Multiple interventional options exist to close the left atrial appendage, but the Watchman device is the only one that compares favorably with warfarin in randomized controlled trials.

Abstract
Atrial fibrillation (AF) and chronic kidney disease (CKD) are strictly related; several independent risk factors of AF are often frequent in CKD patients. AF prevalence is very common among these patients, ranging between 15% and 20% in advanced stages of CKD. Moreover, the results of several studies showed that AF patients with end stage renal disease (ESRD) have a higher mortality rate than patients with preserved renal function due to an increased incidence of stroke and an unpredicted elevated hemorrhagic risk. Direct oral anticoagulants (DOACs) are currently contraindicated in patients with ESRD and vitamin K antagonists (VKAs), remaining the only drugs allowed, although they show numerous critical issues such as a narrow therapeutic window, increased tissue calcification and an unfavorable risk/benefit ratio with low stroke prevention effect and augmented risk of major bleeding. The purpose of this review is to shed light on the applications of DOAC therapy in CKD patients, especially in ESRD patients.

Abstract
PURPOSE The left atrial appendage (LAA) is believed to be a source for thrombus formation and an ancillary structure involved in the initiation and maintenance of atrial fibrillation (AF). LAA ligation has been proposed as adjunctive therapy for the treatment of AF. This study will determine the feasibility of a percutaneous epicardial approach for LAA ligation. METHODS The pericardium of 5 dogs was accessed via percutaneous subxyphoid approach. A 20F epicardial cannula was inserted into the pericardial space and contrast-injected to visualize the LAA. Under fluoroscopic guidance, a suction cup catheter was inserted and attached to the LAA. A 12F snare device was inserted over the vacuum cup to ligate the LAA. The closure of the LAA was verified with LA angiography, in the first 2 dogs, and ICE in all 5 animals. All animals were sacrificed for post hoc assessment of LAA closure. RESULTS All 5 dogs underwent successful epicardial suture ligation of the LAA. In the first 2 dogs, LA angiography demonstrated complete closure of the LAA. All dogs underwent gross examination of the LAA. Post hoc assessment was notable for a small well-circumscribed hematoma on the LAA, consistent with point of suction cup attachment, as well as complete closure of the entire LAA. No laceration or perforation was noted on the LAA. CONCLUSIONS Exclusion of the LAA via a novel percutaneous epicardial-only approach was successful without complications. This demonstrates the feasibility of this technique in an animal model, and may provide an effective approach for epicardial-only LAA exclusion in humans.

Abstract
Background:
Interventional therapies aiming at excluding the left atrial appendage (LAA) from systemic circulation have been established as a valid alternative to oral anticoagulation in patients at high thromboembolic risk. However, their efficacy on stroke prophylaxis may be compromised owing to incomplete LAA closure. Additionally, the need for an alternative thromboembolic prevention may remain unmet in patients with contraindications to oral anticoagulation whose appendage anatomy is unsuitable for some conventional devices commercially available. We aimed at evaluating the feasibility of LAA closure with the novel Gore Cardioform Septal Occluder in patients with incomplete appendage ligation or anatomic features which do not meet the manufacturer’s requirements for Watchman deployment.
Methods:
Twenty-one consecutive patients (mean age: 72±6 years; 85.7% males; CHA
2
DS
2
-VASc: 4.5±1.4; HAS-BLED: 3.6±1.0) were included. Transesophageal echocardiography was performed within 2 months to assess for residual LAA patency.
Results:
Fourteen patients had incomplete LAA closure following surgical (n=6) or Lariat ligation (n=8). In 7 patients with an appendage anatomy unsuitable for Watchman deployment, the mean maximal landing zone size and LAA depth were 14.4±1.3 and 18.6±2.8 mm. Successful Cardioform Septal Occluder deployment was achieved in all patients. No peri-procedural complications were documented. Procedure and fluoroscopy times were 46±13 and 14±5 minutes. Follow-up transesophageal echocardiography after 58±9 days revealed complete LAA closure in all patients.
Conclusions:
Transcatheter LAA closure via a Cardioform Septal Occluder device might be a valid alternative in patients with residual leaks following failed appendage ligation or whose LAA anatomy does not meet the minimal anatomic criteria to accommodate a Watchman device.

Abstract
PURPOSE Optimal stroke prevention strategies for patients with atrial fibrillation (AF) who experience a major bleed are poorly defined. We sought to estimate the effectiveness and safety of oral anticoagulation (OAC) represcription after an OAC contraindication. METHODS TREAT-AF is a retrospective cohort study of patients with newly diagnosed AF (2004-2012), treated in the Veterans Health Administration. From this cohort, we identified patients with a contraindication to OAC after AF diagnoses, defined as incident intracranial bleeding, non-intracranial bleeding requiring hospitalization, or unrepaired cerebral aneurysm or aortic dissection. We used multivariate Cox proportional hazards to estimate the association of OAC prescription in the 90 days following OAC contraindication to ischemic stroke and rebleeding. RESULTS Among 167,190 patients with newly diagnosed AF (70 ± 11 years, 1.7% female, CHA2DS2-VASc 2.7 ± 1.7), 19,285 patients (11.5%) had an incident bleed (n = 18,342) or an unrepaired cerebral aneurysm or aortic dissection (n = 943). For OAC-contraindicated patients with a CHA2DS2-VASc ≥2 (N = 16,194), OAC was represcribed in 4075 patients (25%) and was associated with a higher risk of non-intracranial bleeding (HR 1.49; 95% CI 1.37-1.61; p < 0.0001) but no difference in intracranial bleeding. There was a trend toward decreased stroke risk (HR 0.85; 95% CI 0.71-1.02; p 0.09). CONCLUSIONS Development of contraindication to OAC after diagnosis of AF is common (11.5%), with most events requiring hospitalization. OAC reinitiation was associated with non-intracranial bleeding risk, with a trend toward reduced stroke risk. These data suggest that stroke prevention approaches after major bleeding events could be beneficial if bleeding risk can be successfully mitigated.

Abstract
AF is associated with an increased risk of thromboembolic events, which is usually managed with oral anticoagulation therapy. However, despite a broad range of anticoagulant options and improved uptake in anticoagulation over the past decade, there are some limitations to this approach. Percutaneous left atrial appendage occlusion has been shown to be an effective alternative in this setting, and population data suggest a clear demand for this procedure. Over the past decade, several important changes to the commissioning and delivery of this service have occurred in the UK. In this article, the authors describe the use of percutaneous left atrial appendage occlusion in the UK and discuss the challenges that lie ahead.

Abstract
The pericardial space provides a unique vantage point to access different cardiac structures for diagnosis and treatment of arrhythmias and other nonelectrophysiologic conditions, such as heart failure. There have been notable innovations to improve safety of percutaneous pericardial access and its use for various procedures. Percutaneous pericardial device therapies for pacing and defibrillation have been in development, success of which will be a significant advance in treatment of bradyarrhythmias, cardiac resynchronization therapy, and prevention of arrhythmic deaths. There is need for continued efforts in development and expansion of this technique and a systematic approach to monitor efficacy and safety outcomes.

Abstract
AbstractThere are several situations whereby oral anticoagulation may be unsuitable for stroke prevention in patients with atrial fibrillation (AF). Percutaneous left atrial appendage (LAA) occlusion has received much attention in this area. Various devices have already been developed and tested for this purpose. Data from registries and cohort studies have indicated favourable short- and long-term outcomes with LAA occlusion, and several international guidelines recommend its use in AF patients with contraindications to oral anticoagulation. However, prospective controlled trials in this very population are lacking. Furthermore, while modelling studies on cost analyses have suggested that LAA occlusion may be a cost-effective strategy compared with standard medical therapy, these have not been performed in high-risk patients who may have limited survival in the medium to long term. Thus, while LAA occlusion offers promise, there is a strong need for additional research to investigate its exact role, its long-term outcomes and cost efficacy.

Abstract
Atrial fibrillation (AF) is one of the most frequent causes of ischemic stroke. Without treatment the annual risk of ischemic stroke is on average approximately 5-6%/year in patients with atrial fibrillation, depending on the overall cardiovascular risk profile. Oral anticoagulation with new oral anticoagulants (NOAC) or vitamin K antagonists (VKA) is recommended for patients with AF and an elevated risk for stroke (CHA2DS2-VASc score ≥1); however, severe bleeding complications are potential reasons for discontinuation of this treatment. Overall, up to 30 % of the patients with AF remain without effective thromboembolism prophylaxis. Left atrial appendage (LAA) closure represents an alternative to pharmaceutical stroke prevention. Catheter-based and surgical LAA closure techniques are available. For catheter-based procedures with closure systems, high implantation success rates and relatively low periprocedural complication rates have been observed in recent registry studies. The reason for the restrained recommendation in the European guidelines is the as yet limited experience from large randomized studies.

Abstract
BACKGROUND Pericardial access is complicated by two difficulties: confirming when the needle tip is in the pericardial space, and avoiding complications during access, such as inadvertently puncturing other organs. Conventional imaging tools are inadequate for addressing these difficulties, as they lack soft-tissue markers that could be used as guidance during access. A system that can both confirm access and avoid inadvertent organ injury is needed. METHODS A 21G micropuncture needle was modified to include two small electrodes at the needle tip. With continuous bioimpedance monitoring from the electrodes, the needle was used to access the pericardium in porcine models (n = 4). The needle was also visualized in vivo by using an electroanatomical map (n = 2). Bioimpedance data from different tissues were analyzed retrospectively. RESULTS Bioimpedance data collected from the subcutaneous space (992.8 ± 13.1 Ω), anterior mediastinum (972.2 ± 14.2 Ω), pericardial space (323.2 ± 17.1 Ω), mid-myocardium (349.7 ± 87.6 Ω), right ventricular cavity (235.0 ± 9.7 Ω), lung (1142.0 ± 172.0 Ω), liver (575.0 ± 52.6 Ω), and blood (177.5 ± 1.9 Ω) differed significantly by tissue type (P < .01). Phase data in the frequency domain correlated well with the needle being in the pericardial space. A simple threshold analysis effectively separated lung (threshold = 1120.0 Ω) and blood (threshold = 305.9 Ω) tissues from the other tissue types. CONCLUSIONS Continuous bioimpedance monitoring from a modified micropuncture needle during pericardial access can be used to clearly differentiate tissues. Combined with traditional imaging modalities, this system allows for confirming access to the pericardial space while avoiding inadvertent puncture of other organs, creating a safer and more efficient needle-access procedure.

Abstract
Left atrial appendage occlusion is an evolving technology with demonstrable benefits of stroke prophylaxis in patients with atrial fibrillation unsuitable for anticoagulation. This has resulted in the development of a plethora of transcatheter devices to achieve epicardial exclusion and endocardial occlusion. In this review, the authors summarize the differences in technique, target patient population, outcomes, and complication profiles of endocardial and epicardial techniques.

Abstract
Left atrial appendage (LAA) is the dominant source of systemic thromboembolic (TE) events in patients with nonvalvular atrial fibrillation (AF). In patients with significant bleeding risk, various LAA exclusion strategies have been developed as an alternative to pharmacologic TE prophylaxis. Nevertheless, in a relatively small percentage of patients, incomplete LAA closure can be documented, either at the time of procedure or during follow-up. This persistent patency can potentially jeopardize an effective stroke prophylaxis. Hereby, we report an update on the current clinical implications of LAA leaks and how to manage them.

Abstract
Abstract
Aims
We report the collective European experience of percutaneous left atrial appendage (LAA) suture ligation using the recent generation LARIAT+ suture delivery device.
Methods and results
A total of 141 patients with non-valvular atrial fibrillation and contraindication to oral anticoagulation (OAC), thrombo-embolic events despite OAC or electrical LAA isolation were enrolled at seven European hospitals to undergo LAA ligation. Patients were followed up by clinical visits and transoesophageal echocardiography (TOE) following LAA closure. Left atrial appendage ligation was completed in 138/141 patients (97.8%). Three patients did not undergo attempted deployment of the LARIAT device due to pericardial adhesion after previous epicardial ventricular tachycardia ablation (n = 1), a pericardial access-related complication (n = 1), and multiple posterior LAA lobes (n = 1). Serious 30-day procedural adverse events occurred in 4/141 patients (2.8%). There were two device-related LAA perforations (1.4%) not resulting in any corrective intervention as the LAA was completely sealed with the LARIAT. Minor adverse events occurred in 19 patients (13.5%), including two pericardial effusions due to procedure-related pericarditis requiring pericardiocentesis. Transoesophageal echocardiography was performed after LAA ligation in 103/138 patients (74.6%) after a mean of 181 ± 72 days. Complete LAA closure was documented in 100 patients (97.1%). Two patients (1.8% of patients with follow-up) experienced a transient ischaemic attack at 4 and 7 months follow-up, although there was no leak observed with TOE. There were two deaths during long-term follow-up which were both not device related.
Conclusion
Initial experience with the LARIAT+ device demonstrates feasibility of LAA exclusion. Further larger prospective studies with longer follow-up are warranted.

Abstract
BACKGROUND Percutaneous left atrial appendage closure (pLAAC) emerged as an option for stroke prevention in patients with atrial fibrillation ineligible for long-term anticoagulation. Real-world data on pLAAC's in-hospital and 30-day readmission measures are limited. OBJECTIVE We sought to report the nationwide incidence of the above outcomes using 2016 claims data. METHODS We used the National Inpatient Sample for in-hospital outcomes and Nationwide Readmissions Database for readmissions. We identified hospitalizations with a primary diagnosis of atrial fibrillation and pLAAC procedure by using International Classification of Diseases, Tenth Revision codes and compared the outcomes mentioned above between the endocardial and epicardial cohorts. Statistical analyses were performed using R 3.3.2. RESULTS Among 5480 pLAAC procedures (endocardial: 5145; epicardial: 335), the in-hospital mortality was 0.3%. Endocardial left atrial appendage closure (LAAC) had lower complications (8.5% vs 25.4%; P < .001) and shorter length of stay median [interquartile range] 1 [1-1] day vs 2 [1-3] days; P < .001) but higher hospitalization cost (24.13 [18.45-30.17] × 1000 dollars vs 21.21 [14.03-27.86] × 1000 dollars; P = .016). The most common complications include pericardial (endocardial vs epicardial: 3% vs 10.4%; P < .001) and renal failure (1.4% vs 6.0%; P = .004). Epicardial LAAC had higher 30-day unplanned readmissions (19.5% vs 8.3%; P = .001), with the most common reason being pericarditis and/or effusion (33.9%). CONCLUSION Endocardial LAAC had lower complications and 30-day readmissions but higher hospitalization cost. Although epicardial LAAC showed higher complications, given recent improvements in its technique, and postprocedural care demonstrated a significant reduction in pericardial complications, more contemporary data comparing these outcomes are needed.

Abstract
INTRODUCTION Hyponatremia commonly follows percutaneous exclusion of the left atrial appendage (LAA) with the LARIAT suture delivery device. The aim of this study was to evaluate for clinical predictors hyponatremia following ligation of the appendage with the LARIAT device. METHODS AND RESULTS A retrospective analysis was conducted on 61 consecutive patients (average age 69.7 ± 9.8 years, 55.7% male) who underwent successful appendage ligation with the LARIAT device. Acute hyponatremia (AH) was defined as a drop in serum sodium (Na) by greater than or equal to 4 mmol/L within 48 hours of ligation while exaggerated acute hyponatremia (EAH) was defined as a drop greater than or equal to 10 mmol/L. Among all patients, there was a significant decrease in [Na] at 24 hours (3.26 ± 2.77 mmol/L) and 48 hours (4.98 ± 3.74 mmol/L). Thirty-two patients (52.4%) had AH while six patients (9.8%) experienced EAH. A body mass index (BMI) of less than 28.4 kg/m2 was associated with AH (P = .037) while a BMI < 25 kg/m2 was associated with EAH (P = .021). A linear regression analysis comparing the maximum sodium decrease to the indexed left atrial (LA) diameter found that for every 1 cm/m2 increase in indexed LA diameter, there was a 2.5 mEq/L decrease in serum sodium (P = .04). CONCLUSIONS Hyponatremia frequently occurs following LAA ligation with the LARIAT device. A low BMI < 25 kg/m2 is associated with a drop in serum sodium of greater than 10 mmol/L while increasing indexed LA diameter predicts any AH. AH is also associated with a significantly lower systolic blood pressure 48 to 72 hours post LAA exclusion with the LARIAT device.

Abstract
BACKGROUND Atrial fibrillation (AF) is the most common cardiac arrhythmia. Although treatment options for AF exist, many patients cannot be maintained in normal sinus rhythm. Amiodarone is an effective medication for AF but has limited clinical utility because of off-target tissue toxicity. METHODS Here, we use a pig model of AF to test the efficacy of an amiodarone-containing polyethylene glycol-based hydrogel. The gel is placed directly on the atrial epicardium through the pericardial space in a minimally invasive procedure using a specially designed catheter. RESULTS Implantation of amiodarone-containing gel significantly reduced the duration of sustained AF at 21 and 28 days; inducibility of AF was reduced 14 and 21 days post-delivery. Off-target organ drug levels in the liver, lungs, thyroid, and fat were significantly reduced in animals treated with epicardial amiodarone gel compared with systemic controls in small-animal distribution studies. CONCLUSIONS The pericardium is an underutilized therapeutic site and may be a new treatment strategy for AF and other cardiovascular diseases.

Abstract
The left atrial appendage has been implicated as a major nidus for thrombus formation, particularly in atrial fibrillation. This discovery has prompted substantial interest in the development of left atrial appendage exclusion devices aimed at decreasing systemic thromboembolism risk. Its deceptively simple appearance belies the remarkable complexity that characterizes its anatomy and physiology. We highlight the key anatomic features and variations of the left atrial appendage as well as its relationships with surrounding structures. We also summarize crucial anatomic factors that should be taken into account by the interventional cardiologist when planning for or performing left atrial appendage exclusion procedures.

Abstract
A percutaneous left atrial appendage (LAA) occlusion using a Watchman device was performed in a patient with prior biatrial anastomosis orthotopic heart transplant (OHT). Due to the anatomical changes following biatrial anastomosis, transesophageal echocardiography (TEE) imaging and transseptal puncture become technically challenging. We describe how the standard LAA views on TEE were obtained for device sizing, and how the transseptal puncture was modified to cross the scarred septum. This case demonstrates that LAA occlusion using a Watchman device in biatrial anastomosis OHT is safe and can successfully be done.

Abstract
BACKGROUND Concomitant diabetes mellitus (DM) in atrial fibrillation (AF) may increase the risk of thromboembolism. Left atrial appendage occlusion (LAAO) is an alternative treatment in AF patients in whom antithrombotic therapy is ineffective or contraindicated. The aim of this study was to evaluate the long-term efficacy of LAAO in DM patients with AF. METHODS A retrospective study was conducted in 139 patients who had undergone LAAO and were categorized into two groups: 28 patients with DM and 111 patients without DM. Overall, the follow-up period was 530 patient-years. RESULTS Mean CHADS2 and CHA2 DS2 -VASc scores were higher in patients with than without DM (2.6 vs 1.7 [P < 0.001] and 3.5 vs 2.8 [P = 0.056], respectively). There were no significant differences between the two groups in terms of HAS-BLED scores and other patient factors (sex, age, heart failure, hypertension, previous stroke or transient ischemic attack, peripheral vascular disease) that may increase the risk of thromboembolism based on CHA2 DS2 -VASc. The mean follow-up period was 51.6 and 50 months in patients with DM and without DM, respectively. Comparing patients with and without DM, there were no significant differences in thromboembolic events (4% vs 1.9%), severe bleeding (0% vs 3.1%), or mortality (4% vs 5.9%). The estimated reductions in thromboembolic and bleeding risk were 77% and 100%, respectively, for patients with DM, compared with 85% and 62%, respectively, for patients without DM. CONCLUSION The present study indicates that LAAO in AF patients with DM has similar safety endpoints and long-term efficacy as LAAO in patients without DM.
