ABSTRACT

BACKGROUND: Superior vena cava (SVC) is atrial fibrillation (AF)'s most common non-pulmonary vein (PV) foci. Studies reported conflictory results when SVC isolation (SVCi) was combined with PVi and long-term outcomes were lacking. Therefore, we aimed to evaluate the long-term efficacy and safety of empirical SVCi as an adjunct to cryoballoon-based PV isolation (PVi) in persistent AF ablation. METHODS: A total of 40 consecutive persistent AF patients (60.6 ± 8.2 years, 52.5% females) who underwent SVCi in addition to PVi compared with a propensity score matched cohort of 40 persistent AF patients (58.6 ± 8.7 years, 50% female) in whom PVi-only was performed. Second-generation cryoballoon (CB2) was used in all procedures. Atrial tachyarrhythmia (ATa) recurrence was defined as the detection of AF, atrial flutter, or atrial tachycardia (≥30 s) after a 3-month blanking period. RESULTS: Pulmonary veins and SVC were successfully isolated in all patients. At a mean of 46.7 ± 7.8 months follow-up, 22 (55%) patients in the PVi-only group, and 27 (67.5%) patients in the PVi + SVCi group were free of ATa after the index procedure (P =.359). Phrenic nerve injury (PNI) was detected in 2 (5%) patients in the PVi-only group (during right PVi) and 2 (5%) patients in the PVi + SVCi group (during SVCi) (P = 1.00). Cox regression analysis revealed that early recurrence was the only predictor of recurrence (hazard ratio 4.88, 95% confidence interval 1.59-14.96; P =.005). CONCLUSION: Long-term results of our small sample-sized study revealed that CB-based PVi + SVCi was associated with outcomes similar to the PVi-only strategy in patients with persistent AF. Although complication rates were similar between the groups, close follow-up of diaphragmatic movement is crucial to prevent PNI during SVCi.

ABSTRACT

Atrial tachycardia (AT) is a common rhythm disorder, especially in patients with atrial structural abnormalities. Although voltage mapping can provide a general picture of structural alterations which are mainly secondary to prior ablations, surgery or pressure/volume overload, data is scarce regarding the functional characteristics of low voltage regions in the atrium to predict critical isthmus of ATs. Recently, functional substrate mapping (FSM) emerged as a potential tool to evaluate the functionality of structurally altered regions in the atrium to predict critical sites of reentry. Current evidence suggested a clear association between deceleration zones of isochronal late activation mapping (ILAM) during sinus/paced rhythm and critical isthmus of reentry in patients with left AT. Therefore, these areas seem to be potential ablation targets even not detected during AT. Furthermore, abnormal conduction detected by ILAM may also have a role to identify the potential substrate and predict atrial fibrillation outcome after pulmonary vein isolation. Despite these promising findings, the utility of such an approach needs to be evaluated in large-scale comparative studies. In this review, we aimed to share our experience and review the current literature regarding the use of FSM during sinus/paced rhythm in the prediction of re-entrant ATs and discuss future implications and potential use in patients with atrial low-voltage areas.

ABSTRACT

BACKGROUND: The study explores left atrial appendage closure (LAAC) as a safe and effective alternative to anticoagulation for atrial fibrillation (AF) patients at high bleeding risk. Complications, such as cardioembolic events due to left atrial appendage thrombus (LAAT), highlight the need for alternative stroke prevention strategies. AIMS: This research assesses LAAC's safety and efficacy in patients with LAAT, aiming to offer valuable insights into its potential as a viable option for stroke prevention in such cases. METHODS: The study included 205 patients who underwent LAAC using specific devices between September 2015 and February 2023. Among them, 32 patients had persistent LAAT. Baseline characteristics, antithrombotic medications, risk scores, and LAAC indications were documented. Patients were followed to monitor significant clinical events like stroke, cardiovascular mortality, and all-cause mortality. RESULTS: The mean age was 71.9 and mostly female. Indications for LAAC were ischemic cerebrovascular events (CVE) despite anticoagulation (25%), bleeding complications (major/minor, 37.5% each), or both. Successful LAA closure was achieved in all cases, with minimal pericardial effusion in one. One-month follow-up showed no major events or device-related issues. Median follow-up of 16.5 months saw 21.9% non-cardiac deaths. The study underscores LAAC's efficacy for stroke prevention in patients with persistent LAAT. CONCLUSIONS: The LAAC in cases of LAAT, whether pursued initially or as a deferred approach, demonstrates feasibility and safety, exhibiting notable procedural success and minimal incidence of periprocedural complications.

ABSTRACT

Ictal asystole (IA) is a rare but potentially life-threatening complication of focal epilepsy. The sudden onset of loss of consciousness and drop attacks in a patient with chronic epilepsy should suggest the possibility of this complication. Once the diagnosis is established, rapid management should be considered, especially in high-risk cases. The approach does not differ between temporal and extratemporal lobe epilepsies. Strategies can be aimed at preventing the emergence of cortical epileptic activity from the beginning (surgery, antiseizure therapy), neutralizing negative chronotropic effects on the heart (cardiac neuromodulation), or restarting the heart rhythm with a pacemaker. Pacemaker implantation is not a completely complication-free treatment, and living with a device that requires care and follow-up throughout life makes alternative treatment methods more valid for young patients with many years to live or cases that could benefit from surgery. In this article, we present a patient with a left occipital glioneuronal tumor and drug-resistant occipital lobe epilepsy. IA was documented by long-term video EEG monitoring (VEM). During about 2 years of follow-up after a cardiac neuromodulation procedure, there were no drop attacks or asystole with seizures, confirmed by long-term VEM.

ABSTRACT

Cryoballoon-based catheter ablation has emerged as an efficacious and safe therapeutic intervention for patients with paroxysmal atrial fibrillation (PAF). PAF is primarily associated with the triggers in the pulmonary vein (PV). However, persistent atrial fibrillation (PeAF) is a complex condition that involves changes in the atrial substrate and the presence of non-PV triggers. Therefore, a comprehensive treatment approach is necessary for patients with PeAF. Utilizing a 3D electroanatomical map, the radiofrequency-based ablation technique adeptly identifies and targets the atrial substrate and non-PV triggers. On the other hand, the cryoballoon-based AF ablation was initially designed for PV isolation. However, its single-shot feature makes it a great choice for electrophysiologists looking to address non-PV triggers. It is possible to target the left atrial appendage (LAA), superior vena cava (SVC), left atrial roof, and posterior wall using the apparatus's unique configuration and ablation abilities. This review focuses on the increasing literature regarding cryoballoon-based methods for non-PV trigger ablation. Specifically, it delves into the technical procedures used to isolate the LAA, SVC, and ablate the left atrial roof and posterior wall.

ABSTRACT

Functional atrial mapping is an emerging mapping modality to predict potential critical sites with a role in the maintenance of tachycardia. We report a case of atrial late activation mapping under sinus rhythm predicting the critical isthmus of a left atrial tachycardia. Our findings demonstrate the utility of an atrial isochronal late-activation mapping approach to predict the critical isthmus of re-entry.

ABSTRACT

BACKGROUND: Atrial tachycardia (AT) is a commonly encountered rhythm disorder in patients with underlying atrial scar. The role of atrial late activation mapping during sinus rhythm to predict the critical isthmus (CI) of AT has yet to be systematically evaluated. We aimed to investigate the relationship between the functional substrate mapping (FSM) characteristics and the CI of reentrant ATs in patients with underlying atrial low-voltage areas. METHODS: Patients with history of left AT who underwent catheter ablation with 3D mapping using high-density mapping were enrolled. Voltage map and isochronal late activation mapping were created during sinus/paced rhythm to detect deceleration zones (DZ). Electrograms with continuous-fragmented morphology were also tagged. After induction of AT, activation mapping was performed to detect CI of the tachycardia. Atrial tachyarrhythmia (ATa) recurrence was defined as detection of atrial fibrillation or AT (≥30 s) during the follow-up. RESULTS: Among 35 patients [mean age: 62 ± 9, gender: 25 (71.5%) female] with left AT, a total of 42 reentrant ATs induced. Voltage mapping during sinus rhythm revealed low-voltage area of 37.1 ± 23.8% of the left atrium. The mean value of bipolar voltage, EGM duration, and conduction velocity during sinus rhythm corresponding to CI of ATs were 0.18 ± 0.12 mV, 133 ± 47 ms, and 0.12 ± 0.09 m/s, respectively. Total number of DZs per chamber was 1.5 ± 0.6, which were located in the low-voltage zone (<0.5 mV) detected by high-density mapping. All CIs of reentry were colocalized with DZs detected during FSM. The positive predictive value of DZs to detect CI of inducible ATs is 80.4%. Freedom from ATa after the index procedure was 74.3% during a mean follow-up of 12.2 ± 7.5 months. CONCLUSION: Our findings demonstrated the utility of FSM during sinus rhythm to predict the CI of AT. DZs displayed continuous-fragmented signal morphology with slow conduction which may guide to tailor ablation strategy in case of underlying atrial scar.

ABSTRACT

INTRODUCTION: Recent reports highlighted the role of epicardial connections in the development of biatrial tachycardia circuits. METHODS: We reported a case of 60-year-old female patient who was admitted with recurrent atrial tachycardia (AT) after endocardial pulmonary vein isolation and anterior mitral line formation. RESULTS: Epicardial activation map demonstrated fragmented continuous potentials at the Bachmann's bundle region with good entrainment response. Epicardial radiofrequency ablation terminated AT with complete block in the anterior mitral line. CONCLUSIONS: This case corroborates the data relevant to the role of interatrial connections-specifically Bachmann's bundle-in biatrial macroreentrant ATs and demonstrates that epicardial mapping is an effective method to identify the entire reentrant circuit.

ABSTRACT

There is emerging data indicating that long-standing vigorous exercise may be associated with atrial structural remodelling. This remodelling process is may be the cause of the increasing frequency of atrial arrythmias in athletes. Early diagnosis of atrial remodelling by atrial imaging could have a role in management of atrial arrythmias in elite athletes. In this study we aimed to diagnose early phases of atrial remodelling in elite athletes. Two groups of athletes including professional weight lifters (n = 33), professional marathoners (n = 32) and sedentary participants (n = 30) were enrolled. We also studied patients who received cardiotoxic chemotherapy (n = 10) for comparison. Serum TGF-beta level as a marker of fibrosis was measured. Both left atrial (LA) 3D volume and strain values were analysed. There was a positive correlation between serum TGF-beta levels and LA volumes and negative correlation between TGF-beta levels and strain values. TGF-beta levels were higher among chemotherapy and weight lifter groups, compared to control and marathoner groups [mean 0.57 ± 0.3 and 0.55 ± 0.2 vs. 0.45 ± 0.2 and 0.47 ± 0.2, respectively, p = 0.005]. LA volumes were higher among chemotherapy and weight lifter groups [median 33 (26-38) and 31 (23-36) respectively, p = 0.005], and strain values were lower in these two groups [mean 20.3 ± 2.5 and 24.6 ± 4.5, respectively, p < 0.005] compared to control and marathoner groups. Total exercise volume was higher in weight lifter group compared to marathoners [13,780 (2496-36,400) vs. 4732 (780-44928), respectively, p = 0.001]. There wasn't any difference between any group regarding left ventricular systolic and diastolic functions. Vigorous exercise causes atrial remodelling and fibrosis in elite athletes. Strength exercise carries higher risk for atrial fibrosis than endurance exercise. Burden of exercise is correlated with the severity of cardiac fibrosis. Echocardiographic evaluation of the left atrium and TGF-beta levels may help to detect subclinical cardiac remodelling and fibrosis.

ABSTRACT

BACKGROUND: The present study aimed to identify the frequency of Fabry disease in patients with cardiac hypertrophy of unknown etiology and to evaluate demographic and clinical characteristics, enzyme activity levels, and genetic mutations at the time of diagnosis. METHODS: This national, multicenter, cross-sectional, single-arm, observational registry study was conducted in adult patients with a clinical echocardiographic diagnosis of left ventricular hypertrophy and/or the presence of prominent papillary muscle. In both genders, genetic analysis was performed by DNA Sanger sequence analysis. RESULTS: A total of 406 patients with left ventricular hypertrophy of unknown origin were included. Of the patients, 19.5% had decreased enzyme activity (≤2.5 nmol/mL/h). Although genetic analysis revealed GLA (galactosidase alpha) gene mutation in only 2  patients (0.5%), these patients were considered to have probable but not 'definite Fabry disease' due to normal lyso Gb3 levels and gene mutations categorized as variants of unknown significance. CONCLUSION: The prevalence of Fabry disease varies according to the characteristics of the population screened and the definition of the disease used in these trials. From cardiology perspective, left ventricular hypertrophy is the major reason to consider screening for Fabry disease. Enzyme testing, genetic analysis, substrate analysis, histopathological examination, and family screening should be performed, when necessary, for a definite diagnosis of Fabry disease. The results of this study underline the importance of the comprehensive use of these diagnostic tools to reach a definite diagnosis. The diagnosis and management of Fabry disease should not be based solely on the results of the screening tests.

ABSTRACT

AIMS: There is an increasing trend evaluating the role of non-pulmonary vein (PV) triggers to improve ablation outcomes in persistent atrial fibrillation (AF) as pulmonary vein isolation (PVI) strategy alone has modest outcomes. We investigated the long-term safety and efficacy of left atrial appendage isolation (LAAi) in addition to PVI using cryoballoon (CB) in persistent AF. METHODS AND RESULTS: In this multicentre retrospective analysis, we included a total of 193 persistent AF patients (mean age: 60 ± 11 years, 50.3% females) who underwent PVI and LAAi using CB. Baseline and follow-up data including electrocardiography (ECG), 24 h Holter ECGs, and echocardiography were recorded for all patients. Atrial tachyarrhythmia (ATa) recurrence was defined as the detection of AF, atrial flutter, or atrial tachycardia (≥30 s) after a 3-month blanking period. At a median follow-up of 55 (36.5-60.0) months, 85 (67.9%) patients with PVI + LAAi were in sinus rhythm after the index procedure. Ischaemic stroke/transient ischemic attack occurred in 14 (7.2%) patients at a median of 24 (2-53) months following catheter ablation. Multivariate regression analysis revealed heart failure with preserved ejection fraction [hazard ratio (HR) 2.29, 95% confidence interval (CI) 1.04-5.02; P = 0.038], male gender (HR 0.53, 95% CI 0.29-0.96; P = 0.037), and LA area (HR 1.04, 95% CI 0.53-1.32; P = 0.023) as independent predictors of ATa recurrence. CONCLUSION: Our findings demonstrated that the LAAi + PVI strategy using CB had acceptable long-term outcomes in patients with persistent AF. Systemic thrombo-embolic events are an important concern throughout the follow-up, which were mostly observed in case of non-adherence to anticoagulants.

ABSTRACT

BACKGROUND: The presence of atrial fibrosis has already been known as a risk factor for atrial fibrillation (AF) development. We aimed to evaluate atrial fibrosis with previously defined three different methods, which were cardiac magnetic resonance imaging (C-MRI), echocardiographic strain imaging, and biomarkers and show the relationship between these methods in patients with AF scheduled for cryoballoon ablation. METHODS: A total of 30 patients were enrolled. Atrial T1 relaxation durations were measured using C-MRI before the procedure of atrial fibrillation catheter ablation. Fibroblast growth factor-21 (FGF-21) and fibroblast growth factor-23 (FGF-23) levels were measured at serum derived from the femoral artery (Peripheral FGF 21 and 23) and left atrium blood samples (Central FGF 21 and 23) before catheter ablation. Preprocedural transthoracic echocardiography was performed. The median follow-up duration for atrial tachyarrhythmia (ATa) recurrence was 13 (12-18 months) months. RESULTS: The mean ages of the study group were 55.23 ± 12.37 years, and there were 17 (56.7%) female patients in study population. There were negative correlations between post contrast T1 relaxation durations of both posterior and posterosuperior atrium, and central FGF-23 (r: - 0.561; p = 0.003; r:-0.624; p = 0.001; Posterior T1 vs. central FGF-23 levels and Posterosuperior T1 vs central FGF-23 levels, respectively). The positive correlations were observed between postcontrast posterior T1 relaxation durations and left ventricle ejection fraction (r:0.671; p = 0.001); left atrial emptying fraction (r:0.482; p = 0.013); peak atrial longitudinal strain (r:0.605; p = 0.001), and peak atrial contraction strain (r:0.604; p = 0.001). Also negative correlation was observed between postcontrast posterior T1 relaxation durations, and left atrial volume index (r: - 0.467; p = 0.016).

ABSTRACT

PURPOSE: Cryoballoon (CB) and radiofrequency (RF) ablation techniques have similar outcomes for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF). However, there is limited data about the impact of different ablation strategies in patients with left common pulmonary vein (LCPV). Our aim was to compare the safety and efficacy of RF and CB ablation in AF patients with LCPV. METHODS: One hundred and twenty-seven (n = 80 CB and n = 47 RF) AF patients with LCPV detected by preprocedural computerized tomography (CT) were included in the study. Ostial dimensions and trunk distance were measured in all patients. Atrial tachyarrhythmia (ATa) recurrence was defined as detection of AF, atrial flutter, or atrial tachycardia (≥ 30 s) after a 3-month blanking period. RESULTS: There was no significant difference in acute procedural success rates for PVI (97.5% in CB and 97.9% in RF, respectively, P = 0.953) and complication rates were similar between the groups (6 (7.5%) in CB and 4 (8.5%) in RF, respectively, P = 1.000). During a median follow-up of 20.7 (4.8-50.2) months for CB and 20.5 (6.2-36.0) months for RF, ATa recurrence was 35.0% and 38.2%, respectively (P = 0.777). Multivariate analysis did not reveal any of the morphologic parameters of LCPV as a significant predictor of ATa recurrence. CONCLUSIONS: Our findings demonstrated that both CB and RF ablation techniques have similar efficacy and safety in AF patients with LCPV during the mid-term follow-up.

ABSTRACT

The common ostium of left and right inferior PVs is an extremely rare variant which was only reported in 16 cases undergoing catheter ablation. Thus, electrophysiologists should be careful about such an exremely rare PV variants for the safety and efficacy of ablation. Pre-procedural CTA is a valuable tool to decide on the ablation strategy in patients with such a very rare PV anomaly.

ABSTRACT

OBJECTIVE: The systematic coronary risk evaluation (SCORE) estimates the 10-year risk of fatal cardiovascular disease (CVD), and its application is recommended. The absolute risk of CVD, independent of risk factors, is relatively low in young individuals. Expressing the risk as their "risk age" may aid in understanding the risk. This study aimed to demonstrate a possible correlation between vascular risk age, SCORE risk value, and the level of subclinical atherosclerosis evaluated using a pulse wave velocity (PWV) device. METHODS: This work was designed to be a cross-sectional study. The SCORE 10-year fatal CVD risk and vascular risk age were calculated for patients below the age of 50 years and without any previous diagnosis of atherosclerotic disease or equivalents. The PWV of each patient was measured non-invasively using a PWV device. RESULTS: The study population included a total of 300 patients with a mean age of 35.1±9.5 years. The mean PWV and mean vascular age of the entire study population were 6.3±1.3 m/s and 44.3±5.5 years, respectively, and the median 10-year risk of fatal CVD score was 0.4 (0.04-2.74). There was a positive correlation between PWV and the 10-year risk of fatal CVD (r=0.613; P<0.001) and vascular risk age (r=0.684; P<0.001). CONCLUSION: Despite their young age and low to moderate 10-year risk of fatal CVD (<1%-5%) according to the SCORE chart, patients with a high vascular risk age were found to have high PWV values. These results show that calculations of vascular risk age might be used to assess the risk of fatal CVD in young patients and correlate with subclinical atherosclerosis.

ABSTRACT

BACKGROUND: Powered transvenous lead extraction (TLE) tools are commonly required to remove the leads with long implant duration due to fibrotic adhesions. However, comparative data are lacking among different types of TLE tools. AIM: To compare the efficacy and safety of two different rotational mechanical dilator sheaths in retrospectively analyzed patients who underwent TLE. METHODS AND RESULTS: A total of 566 lead extractions from 302 patients using TightRail™ (333 lead extractions from 169 patients) and Evolution® (233 lead extractions from 133 patients) mechanical dilator sheaths were performed between July 2009 and June 2018. Acute and long-term outcomes of study groups were compared. There is no statistically significant difference between Evolution® and TightRail™ groups in procedural success (93.9% vs. 94%), clinical success (99.2% vs. 98%), and major complications (3.8% vs. 1.2%), respectively (p > .05). In multivariate regression analysis, lead dwell time, the number of extracted leads, and baseline leukocyte count were found as independent predictors of procedural success (p < .05). During the median follow-up of 36.6 (0.2-118) months, all-cause mortality was observed in 73 patients (25.6% in the Evolution® vs. 23.1 in the TightRail™ group, p > .05). Chronic renal disease, heart failure, and coagulopathy were shown as independent predictors of all-cause mortality in multivariate regression analysis (p < .05). CONCLUSION: TLE using TightRail™ or Evoluation® mechanical dilator sheaths was a safe and effective therapeutic option. Both mechanical dilator sheaths showed similar efficacy, safety, and all-cause mortality at acute and long-term follow-up of patients who underwent TLE.

ABSTRACT

OBJECTIVE: Genome-wide association studies have revealed that single nucleotide polymorphisms (SNPs) are associated with atrial fibrillation (AF) and can predict AF recurrence after catheter ablation in different populations. However, there exists no such data for the Turkish population. We aimed to investigate whether 11 SNPs in the PITX2, ZFHX3, EPHX2, CAV1, TBX5, TGF-1, and SCN10A were related to AF and whether these SNPs can predict long-term atrial tachyarrhythmia (ATa) recurrence after pulmonary vein isolation (PVI) for AF in Turkish patients. METHODS: A total of 245 consecutive patients with non-valvular AF (44.9% men, mean age: 60.2±13.2 years, 65.3% paroxysmal AF) and 50 age- and sex-matched controls were included in this analysis. The clinical features and genetic variants were compared between the 2 groups. Of the 245 patients, 128 who underwent PVI with second-generation cryoballoon were further examined for long-term recurrence after the procedure. RESULTS: Four SNPs in PITX2 were significantly associated with AF (rs10033464_T: OR 3.29, 95%CI: 1.38-7.82, p=0.007; rs6838973_T: OR 3.06, 95% CI 1.36-6.87, p=0.007; rs3853445_C: OR 2.84, 95%CI: 1.27-6.36, p=0.011; rs17570669_T: OR 4.03, 95% CI: 1.71-9.51, p=0.001). Among these patients who underwent PVI, one locus in CAV1 (rs3807989_G: OR 4.50, 95% CI 1.04-19.31, p=0.043) and early recurrence (OR: 8.06, 95% CI: 2.12-30.55, p=0.002) predicted long-term AF recurrence after catheter ablation. CONCLUSION: Significant associations exists between 4 SNPs in PITX2 and AF (rs10033464, rs6838973, rs3853445, and rs17570669) in Turkish patients. In addition, 1 genetic variant in CAV1 (rs3807989) and early recurrence can predict long-term ATa recurrence after catheter ablation.

ABSTRACT

OBJECTIVE: In recent years, percutaneous closure of a patent foramen ovale (PFO) has gained widespread use. This study is an evaluation of the safety and efficacy of the Figulla and Amplatzer devices for PFO closure, including long-term follow-up results. METHODS: A total of 305 patients (43.6% male; mean age: 43.25±10.98 years) who underwent percutaneous PFO closure between 2003 and 2019 were enrolled. The Risk of Paradoxical Embolism (RoPE) score was calculated to predict the recurrence risk of cerebrovascular events due to PFO. Transthoracic echocardiography was used during the procedure. RESULTS: The devices were successfully implanted in all patients. The in-hospital periprocedural complications recorded were atrial fibrillation in 1 patient (0.3%), supraventricular tachycardia in 1 patient (0.3%), and femoral hematoma in 3 patients (1%). The procedure time and fluoroscopy time was 21.92±2.93 minutes and 2.19±0.24 minutes, respectively. Recurrent ischemic stroke or transient ischemic attack (TIA) was observed in 7 (2.2%) patients during the median 85.77 months (25th-75th percentile: 10.21-108.00 months) follow-up. The RoPE score was significantly lower in patients with recurrent ischemic cerebral event (stroke or TIA) compared with asymptomatic patients (p<0.001). Kaplan-Meier curve analysis revealed that there was no significant difference between PFO device types (Amplatzer: 2.4% vs. Figulla: 3.3%) in terms of recurrent ischemic cerebral events during follow-up (log-rank; p=0.642). CONCLUSION: Percutaneous PFO closure was safe, feasible, and effective. Our study confirmed the efficacy and safety of transthoracic echocardiogram guidance during percutaneous closure of PFO, which shortens the procedure time. A lower RoPE score was related to the recurrence risk of ischemic cerebrovascular events.
