RESUMEN
OBJECTIVE: This study aims to explore the impact of sodium-glucose cotransporter-2 (SGLT-2) inhibitors, a newer class of oral antidiabetic drugs, on atrial electromechanical delay (EMD) in patients with type 2 diabetes mellitus (DM). This is particularly relevant given the significantly higher incidence of atrial fibrillation (AF) in diabetic patients compared to the general population. Atrial electromechanical delay is recognized as an important factor influencing the development of atrial fibrillation. METHODS: This study included 30 type 2 DM patients (53.3% female, mean age 60.07 ± 10.03 years), initiating treatment with SGLT-2 inhibitors. The patients were assessed using echocardiography at baseline and again at 6 months, focusing on basic echocardiographic parameters and atrial electromechanical delay times (EMD) measured via tissue Doppler imaging. RESULTS: No significant changes were observed in intra-atrial EMD times. However, significant reductions were noted in interatrial EMD times, decreasing from 15.13 ± 5.87 ms to 13.20 ± 6.12 ms (P = 0.029). Statistically significant shortening occurred in lateral pulmonary acceleration (PA) times (from 58.73 ± 6.41 ms to 54.37 ± 6.97 ms, P < 0.001), septal PA times (from 50.90 ± 6.02 ms to 48.23 ± 5), and tricuspid PA times (from 43.60 ± 6.28 ms to 41.30 ± 5.60 ms, P = 0.003). Additionally, there was a significant reduction in the E/e' ratio from 8.13 ± 4.0 to 6.50 ± 2.37 (P = 0.003). CONCLUSION: SGLT-2 inhibitors might positively influence atrial electromechanical conduction, reducing DM-related functional impairments and the risk of arrhythmias, particularly AF.

The increasing number of losses and damages caused by the climate crisis has rendered the psychometric assessment of the climate crisis more important than ever, specifically in developing countries, such as Turkey. The aim of this study was to examine the psychometric properties of the Turkish version of the Hogg Eco-Anxiety Scale (HEAS-13), using exploratory structural equation modeling (ESEM) on the cross-sectional data collected from 445 adults (286 females and 159 males; Mage = 29.76, range 18-65). The results supported the four-factor solution of the original version in the Turkish sample. Further analysis confirmed the invariance of the HEAS-13 across genders. The results demonstrated significant correlations of the HEAS-13 subscales with the Brief Symptom Inventory (BSI) and the Anthropocentric Narcissism Scale (ANS), except for that between the behavioral symptoms subscale of the HEAS-13 and the ANS. Both the total and the subscale scores of the HEAS-13 were also found to be reliable, given the internal consistency and test-retest reliability values. The Turkish version of the HEAS-13 can expand the scientific understanding of eco-anxiety, which can help develop mental health services to mitigate the negative mental health impacts of the environmental crisis.
RESUMEN
The article presents results of using remote sensing images and machine learning to map and assess land potential based on time-series of potential Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) composites. Land potential here refers to the potential vegetation productivity in the hypothetical absence of short-term anthropogenic influence, such as intensive agriculture and urbanization. Knowledge on this ecological land potential could support the assessment of levels of land degradation as well as restoration potentials. Monthly aggregated FAPAR time-series of three percentiles (0.05, 0.50 and 0.95 probability) at 250 m spatial resolution were derived from the 8-day GLASS FAPAR V6 product for 2000-2021 and used to determine long-term trends in FAPAR, as well as to model potential FAPAR in the absence of human pressure. CCa 3 million training points sampled from 12,500 locations across the globe were overlaid with 68 bio-physical variables representing climate, terrain, landform, and vegetation cover, as well as several variables representing human pressure including: population count, cropland intensity, nightlights and a human footprint index. The training points were used in an ensemble machine learning model that stacks three base learners (extremely randomized trees, gradient descended trees and artificial neural network) using a linear regressor as meta-learner. The potential FAPAR was then projected by removing the impact of urbanization and intensive agriculture in the covariate layers. The results of strict cross-validation show that the global distribution of FAPAR can be explained with an R2 of 0.89, with the most important covariates being growing season length, forest cover indicator and annual precipitation. From this model, a global map of potential monthly FAPAR for the recent year (2021) was produced, and used to predict gaps in actual vs. potential FAPAR. The produced global maps of actual vs. potential FAPAR and long-term trends were each spatially matched with stable and transitional land cover classes. The assessment showed large negative FAPAR gaps (actual lower than potential) for classes: urban, needle-leave deciduous trees, and flooded shrub or herbaceous cover, while strong negative FAPAR trends were found for classes: urban, sparse vegetation and rainfed cropland. On the other hand, classes: irrigated or post-flooded cropland, tree cover mixed leaf type, and broad-leave deciduous showed largely positive trends. The framework allows land managers to assess potential land degradation from two aspects: as an actual declining trend in observed FAPAR and as a difference between actual and potential vegetation FAPAR.

OBJECTIVE: Immunoglobulin G4-related disease (IgG4-RD) and chronic tonsillitis are both chronic fibroinflammatory diseases in which tissue atrophy is sometimes observed. In this study, the authors aimed to investigate the pathologic IgG4 positivity in tonsillectomy specimens and hypothesized to name it as a new clinical component of IgG4-RD if there is significant IgG4 positivity in chronic tonsillitis. METHODS: A total of 73 patients who underwent tonsillectomy for chronic tonsillitis were included in this study. Of these, 31 patients had atrophic form chronic tonsillitis. Pathologic examinations and specific IgG4 immunohistochemical staining were performed by the same experienced pathologist in terms of IgG4-RD. RESULTS: Sixty-three percent (n=46) of the cases were male, 37% (n=27) were female, their ages ranged from 3 to 51, and the mean age was 19.11±14.82. It was determined that 23.3% (n=17) of the cases participating in the study were IgG4-positive. When the pathologic grades of the cases were examined; it was observed that 13.7% (n=10) were Grade I, 65.8% (n=48) were Grade II, and 20.5% (n=15) were Grade III. A statistically significant difference was found between the pathology degrees of the cases according to the IgG4 groups ( P =0.001; P <0.01). CONCLUSION: The authors concluded that as the histopathologic grades of chronic lymphoplasmacytic inflammation in tonsils specimen increase, IgG4 positivity rates also increase. Therefore, this clinical entity may be a new IgG4-related disease state in cases with chronic tonsillitis. LEVEL OF EVIDENCE: Level II.

AIM: Sarcopenia is defined as the loss of muscle mass and muscle strength, and its frequency increases in kidney patients. However, sarcopenia frequency in patients with glomerulonephritis is unknown. The present study aimed to investigate the frequency of sarcopenia in patients with glomerulonephritis and compare the results with the healthy population for the first time in the literature. PATIENTS AND METHODS: A total of 110 participants, including 70 patients previously diagnosed with glomerulonephritis and 40 healthy individuals, were included in the study. The diagnosis of sarcopenia was made based on the EWSGOP 2 Criteria. RESULTS: The mean age of the glomerulonephritis patients group was 39.3 ± 1.5. In the anthropometric measurements of the patients, walking speed was low in 50 patients (71.4%), muscle strength was decreased in 44 patients (62.9%), and sarcopenia was detected in 10 patients (14.3%) according to the EWGSOP 2 Criteria. Considering the anthropometric measurements of the control group, sarcopenia was not detected in any of the subjects according to the EWGSOP 2 Criteria. CONCLUSION: The result of the present study revealed that the rate of sarcopenia was significantly higher in glomerulonephritis patients compared to the healthy population and that sarcopenia can also be observed even in middle age in this population. We think it would be beneficial for clinicians treating glomerulonephritis to be more careful regarding sarcopenia and keep these parameters in mind during treatment.

Objectives: The aim of this study was to compare adiponectin, resistin, visfatin, and irisin levels between pregnant women diagnosed gestational diabetes mellitus (GDM) and healthy pregnant women and to evaluate the role of these parameters in GDM pathophysiology and early diagnosis. Methods: Fifty GDM and 50 healthy pregnant women were included in the study. Anthropometric measurements of pregnant women were performed. Fasting blood glucose, hemoglobin A1c, 75 gr OGTT, low density lipoprotein, triglyceride, and complete blood count results were recorded. Adiponectin, irisin, visfatin, resistin, and C-reactive protein (CRP) levels were evaluated. Results: Serum adiponectin levels were significantly lower (p<0.001) and serum resistin and CRP levels were significantly higher (p=0.000 and p=0.027, respectively) in pregnant women with GDM compared to healthy pregnants. There was no significant difference between groups according to serum irisin and visfatin levels (p=0.942 and p=0.332, respectively). There was a negative correlation between adiponectin level and FPG, visfatin, and resistin, while a positive correlation was found between irisin level. While there was a positive correlation between resistin and CRP levels, there was a negative correlation between adiponectin level. While there was a positive correlation between irisin and adiponectin levels, there was a negative correlation between weight and body mass index. Conclusion: In this study, we think that elevated serum resistin and CRP levels and decreased adiponectin levels in GDM patients may play a role in glucose metabolism changes. Further studies are needed on this subject.
RESUMEN
Prolonged pleural effusion is a fairly common condition which has considerable impact on complicated and longer hospital stays after Fontan surgery. Identifying the patient population prone to have pleural effusions is still seeking for an answer. This study is to determine the variables that may predict prolonged pleural effusion according to the data of 69 patients who underwent Fontan operation between June 2018 and December 2020 and survived to date. Prolonged pleural effusion was defined as the need for a chest tube for more than 7 days. Two patient groups, with and without prolonged effusion, were compared in terms of pre-, peri-, and post-operative variables. The patients were subdivided into "high-risk" and "low-risk" groups based on the pre-operative catheterisation data. The most frequent main diagnosis was tricuspid atresia (n: 13, 19%). Among 69 patients, 28 (40%) had prolonged pleural effusion whereas 11 (16%) had effusions that lasted longer than 14 days. Ten patients among prolonged effusion group (35%) had pulmonary atresia coexistent with the main diagnosis. Fontan operation was performed in 6 patients (8.7%) over the age of 10, and 4 of these patients (67%) had prolonged pleural effusion. Among numerous variables, statistical significance between the two groups was achieved in pre-operative mean pulmonary artery pressure, post-operative albumin, C-reactive protein levels, length of hospital stay, duration of chest tube drainage, and amount of effusion per day. Early recognition and treatment strategies with routine medical protocol use remain to be the cornerstone for the management of post-operative prolonged pleural effusions after Fontan surgery.

In this study, the authors aimed to share their experience with 46 patients who were wounded due to terrorism and war in Somalia. The authors also evaluated the etiological diversity of terror-related and war-related injuries. The study included 46 patients treated at the 150-bed Turkey-Somalia Tertiary Hospital between 2019 and 2021. The authors reviewed medical records including data regarding age, sex, trauma etiology, and type of fracture and trauma. For all patients, surgical technique and plate and screw applications were recorded. The authors also assessed complications and outcomes for the patients. The study included 5 women (10.9%) and 41 men (89.1%). The mean age was 30.36 years. It was found that 2 patients (4.35%) presented to the emergency department with stab injuries, 33 patients with blast injuries from improvised explosive devices (71.73%), and 11 patients with firearm injuries. There were 31 patients with maxillary and mandibular fractures, 17 of which had both maxillary and mandibular fractures. There were 14 patients with maxillary fracture alone, including 3 patients with tripod fracture and 7 patients with inferior and lateral rim fracture. There was a mandibular fracture in 17 patients, including 5 patients with parasymphysis fracture, 7 patients with ramus fracture, and 5 patients with multifocal comminuted fracture. It is a challenging process to treat terror-related injuries in our tertiary hospital in Somalia, where all resources are imported from foreign countries. In such settings, authorities should make protective equipment obligatory to prevent civil and military casualties. Trauma hospitals and experienced trauma surgeons should be available.

OBJECTIVES: To demonstrate cerebral arterial flow volume changes during the hypothyroid, euthyroid, and hyperthyroid phases and comparing between laboratory findings and cerebral arterial flow changes with carotid-vertebral duplex Doppler ultrasound (CVA-DUSG) in subclinical Hashimoto thyroiditis (HT) patients. METHODS: According to the TSH level, 3 groups were constructed between patient cases. Group 1 (n=29) was the subclinical hyperthyroid group. In this group, the TSH level was between 0.0005 and 0.3 IU/ml. Group 2 (n=175) was the euthyroid group. TSH level in this group was between 0.3 and 4.2 IU/ml. Group 3 (n=76) was the subclinical hypothyroid group. In this group, the TSH level was above 4.2 IU/ml. The control-group (group 4) (n=71) included healthy people. In this group, the TSH level was between 0.3 and 4.2 IU/ml. After obtaining at least three consecutive waves from the bilateral internal cerebral artery and bilateral vertebral artery, volume flows were calculated using CVA-DUSG. Volume flows were calculated as peak systolic velocity + end diastolic velocity/2 × mean arterial diameter. The mean ICA(Internal Carotid Artery) and VA(Vertebral Artery) diameter was measured per ICA and VA. Total cerebral artery flow volume was defined as right ICA + right VA flow volume and left ICA + left VA flow volume. We also demonstrated topographic cerebral artery blood flow changes. Total ICA flow volume was used to assess the anterior part of the brain, total VA flow volume was used to evaluate the posterior part of the brain, right ICA + right VA flow volume was used to assess the right part of the brain, and left ICA + left VA flow volume was used to verify the left part of the brain. RESULTS: There were significant differences between RVA(Right Vertebral Artery) flow volume, LICA (Left Internal Carotid Artery) flow volume, total flow volume, TSH, and T3 and T4 levels in all groups according to the Dunn's multiple comparison test.(p<0.001) Mean TSH level was 0.03 (0.005-0.06) IU/ml in group 1, 2.8 (1.8-3.97) IU/ml in group 2, 7.32 (6.14-9.93) IU/ml in group 3, and 1.76 (1.17-2.49) IU/ml in the control group. The mean T3 level was 4.18 (3.55-5.38) in group 1, 2.88 (2.63-3.16) in group 2, 2.82 (2.49-3.15) in group 3, 3.14 (2.92-3.15) in the control group. The mean T4 level was 1.92 (1.29-2.5) in group 1, 1.16(1.03-1.31) in group 2, 1.01 (0.91-1.16) in group 3, 1.12 (0.97-1.30) in the control group (group 4). Mean total flow volume was 793 (745-898) ml/min in group 1, 742 (684.25-822.5) ml/min in group 2, 747 (692-824) ml/min in group 3, and 700 (673-675) ml/min in the control group. We also demonstrated topographic cerebral arterial volume flow changes with CVA-DUSG. There was a significant difference among all groups in the right and anterior parts of the brain (p < 0.001), and there was a significant difference between groups 1 and 4 in the left part of the brain (p = 0.009). CONCLUSION: This study demonstrated that total cerebral arterial volume flow increased in the hyperthyroid phase of subclinical HT cases without any internal carotid and vertebral artery diameter changes compared with the euthyroid and hypothyroid phases of subclinical HT and healthy cases. We also verified topographic cerebral arterial blood flow changes in subclinical HT cases with a real-time, easily applicable modality (CVA-DUSG) that does not include X-ray or contrast agents. There was a significant difference between all groups in the right and anterior parts of the brain and there was a significant difference between groups 1 and 4 in the left part of the brain.

INTRODUCTION: Sarcopenia was determined to be associated with increased arterial stiffness in the nondialysis patient population, but there is no available data on this subject in dialysis patients. METHODS: A total of 79 patients were included in the study. Sarcopenia was diagnosed according to the EWSGOP-2 criteria. Arterial stiffness was measured noninvasively with a mobile-O-Graph device. RESULTS: Skeletal muscle mass was observed to be positively correlated with weight, body mass index, creatinine, and uric acid, while negatively correlated with augmentation index. There was a correlation between augmentation index and sodium, phosphorus, systolic blood pressure, diastolic blood pressure, cardiac index, muscle percentage, fat percentage, and skeletal muscle mass. When the determinants of augmentation index in the linear regression analysis were viewed, just the systolic blood pressure and skeletal muscle mass were observed to be the determinant. CONCLUSION: Decreased skeletal muscle mass contributes to increased arterial stiffness in hemodialysis patients.

Objectives: Retrospective analysis of cases diagnosed with brain death in our hospital in the last 15 years. Methods: The files and computer records of the cases diagnosed with brain death in the intensive care units of our hospital between January 2008 and January 2023 were evaluated retrospectively. The demographic data of the cases, the primary disease leading to brain death, the complementary tests used in the diagnosis of brain death, the day on which brain death was diagnosed in the intensive care unit, and the donor status were examined. Results: A total of 228 cases diagnosed as brain death were detected. Seven patients with missing data were excluded from the study. 61.99% of the cases were male, 38.01% were female, 14.02% were under 18 years old, 68.34% were between 18 and 65 years old, 17.64% were over 65 years old. Brain death was diagnosed in 69.69% of the patients admitted to the intensive care unit in the first 7 days, 22.17% in 7-14 days, and 8.14% after 14 days. The primary disease causing brain death was found to be 47% hemorrhagic cerebral injury, 21% traumatic hemorrhagic injury, 18% ischemic cerebral injury, and 14% hypoxic cerebral injury. No ancillary testing was used in 38% of the cases. Carotid doppler ultrasound was used in 36%, computed tomography angiography was used in 22%, and transcranialdoppler was used in 4%. Families agreed to be organ transplant donors in 28.95% of the cases. 71.05% family members refused to be organ transplant donors. Conclusion: The number of organ donations and the diagnosis of brain death has decreased rapidly with the covid-19 pandemic. In order to increase organ donation, we think that the necessary education should be given at an early age to increase organ donation awareness and social awareness.
RESUMEN
In this study, the design of the torsion and compression springs of the foldable wing mechanism used in the missile is considered an optimization problem. After the missile leaves the tube, the wings waiting in a closed state must be opened and fixed within a specific time. The study it is aimed to maximize the energy stored by the springs so that the wing can be opened in a minimum time. In this context, the energy equation in both publications is defined as the objective function in the optimization process. Wire diameter, coiling diameter, coiling number, and deflection parameters required for spring design were determined as optimization variables. There are geometrical constraints for the variables due to the dimensions of the mechanism and there are also safety factor constraints due to the loads to which the springs are exposed. The Bees Algorithm (BA) was used to solve this optimization problem and perform the spring design. The energy values obtained with BA were better than the values obtained with the Design of Experiment (DOE) study before. The springs and mechanism designed with the parameters obtained from the optimization were first analyzed in the ADAMS program. Afterward, experimental tests carried out by integrating the produced springs into the actual mechanism. As a result of the tests, it was observed that the wing opened at approximately 90 ms. This value is well below the project target of 200 ms. In addition, there is only a 16 ms difference between the analysis and the experimental results.

Gestational diabetes mellitus (GDM) is a condition that is very common during pregnancy and has negative consequences for both mother and fetus. Insulin resistance has been shown as an important cause in the pathogenesis of GDM and low-level inflammation is suggested to be one of the underlying causes of insulin resistance. We aimed to investigate whether the neutrophil-lymphocyte ratio (NLR), which is an indicator of systemic inflammation, is a predictor for GDM. A total of 228 pregnant women, including 128 GDM (patient group) and 100 healthy pregnant were included in the study. GDM was diagnosed with a 1-step approach between 24 and 28 weeks of pregnancy. We found a significant increase in NLR in the 1st and 3rd trimesters in the GDM group compared to healthy pregnant women, which supports that systemic inflammation starts in the early stages of pregnancy and continues throughout pregnancy. We also reported a positive correlation between NLR and fasting plasma glucose and body mass index in both trimesters. We showed that first trimester NLR independently predicted the development of GDM.

BACKGROUND: Cardiac autonomic neuropathy is a frequent complication of type 2 diabetes mellitus. Cardiac autonomic neuropathy, in which sympathetic tone predominates over parasympathetic activity, increases both cardiovascular morbidity and mortality and unfortunately has no definitive treatment. Sodium-glucose cotransporter-2 inhibitors have been suggested to reduce sympathetic nervous system activity, based on the results from previous studies. In this study, we aimed to investigate the effect of 24-week treatment with dapagliflozin, a sodium-glucose cotransporter-2 inhibitor, on cardiac autonomic function measures in patients with type 2 diabetes mellitus and cardiac autonomic neuropathy. METHODS: Dapagliflozin 10 mg/day (n=42) or non-sodium-glucose cotransporter-2 inhibitor oral antidiabetic(s) (n=38) was added to the treatment of patients whose glycemic control could not be achieved with existing treatments. The patients with definite or confirmed cardiac autonomic neuropathy diagnosed by cardiovascular autonomic reflex tests underwent 24-hour Holter-electrocardiogram recordings to obtain heart rate variability and heart rate turbulence parameters before starting additional medication and after a 24-week treatment period. RESULTS: In-group analyses showed that dapagliflozin 10 mg/day for 24 weeks improved heart rate variability and heart rate turbulence parameters and decreased the frequency of ventricular premature beats relative to their baseline values. No such findings were observed in the control group despite similar glycemic control. Comparisons between dapagliflozin group and the control group showed that these effects of dapagliflozin were significantly better than non-sodium-glucose cotransporter-2 inhibitor oral antidiabetics. CONCLUSION: Dapagliflozin improves measures of cardiac autonomic function compared to the control group in type 2 diabetic patients with cardiac autonomic neuropathy. This intergroup benefit, demonstrated for the first time, may be promising for the regression of cardiac autonomic neuropathy with sodium-glucose cotransporter-2 inhibitors.

Although balloon-expandable stent implantation for native aortic coarctation is a preferred method in the adolescent age group, there are insufficient data about indications for and the efficacy of the procedure in a younger age group. The aim of this study was to compare and evaluate the data of young pediatric and adolescent patients who underwent balloon-expandable stent implantation because of native aortic coarctation. The retrospective analysis included the demographic characteristics and data related to the procedure and follow-up of patients who underwent stent implantation for native aortic coarctation between August 2010 and November 2017. Patients with re-coarctation were excluded from the study. The patients were separated into 2 groups as the adolescent group (Group I: 10-18 years) and the pediatric group (Group II:â ≤â 9.9 years). Group-I comprised of 18 patients and Group-II, 32 patients. Covered stent was implanted to 32 (73%) patients and uncovered stent to 12 (27%) patients. The procedural success rate was 100%. Following stent implantation, peak systolic gradient decreased significantly in both groups (Pâ <â .0001) (Group-I: from 35.9â ±â 16.6 mm Hg-2.2â ±â 3.4 mm Hg, Group II: from 34â ±â 13.3 mm Hg-3â ±â 4.09 mm Hg). Complications developed in 3 patients, and all in Group I. Femoral hematoma developed in 1 patient, balloon rupture occurred during the procedure in 1 patient, and there was temporary loss of pulse in 1 patient. All the complications were treated successfully. All the patients were taking anti-hypertensive drugs before intervention and during the mean 23-month follow-up period (range, 2-84 months), hypertension recovered in 35 (80%) patients and drugs were terminated. Stent implantation for aortic coarctation in the pediatric age group may provide pleasing results, reducing the coarctation gradient, providing effective dilatation in the lesion area and eliminating hypertension.

We aimed to evaluate the effects of hypogonadism on metabolic and chronic complications in type 2 diabetic males. 261 nonobese males with type 2 diabetes aged 18-70 were involved in the study. Hypononadal males were divided into 2 groups as overt hypogonadism (total testosterone≤230 ng/dl) and borderline hypogonadism (230-345 ng/dl). The control group involved eugonadal diabetic males. Micro-macrovascular complications were recorded. 101 patients had hypogonadism (38.7%), and 160 patients were eugonadal (61.3%). Microvascular complication rate was not different, but macrovascular complication rate was significantly higher in hypogonadal males (42.6%/31.3%, p = 0.042). Optimal glycosylated haemoglobin (HbA1c) achievement(<7%) was significantly lower in hypogonadal patients (20.8%/31.3%, p = 0.043). Poor glycaemic control (HbA1c≥7%), presence of microvascular complication and increased triglyceride levels were independent risk factors for hypogonadism (OR: 1.5, p = 0.044;OR:3.89,p = 0.025 and OR: 1.0, p = 0.016 respectively). Overt hypogonadism, hypertension, hypercholesterolaemia and severe hypoglycaemia were independent risk factors for macrovascular complications (OR: 1.0, p = 0.027; OR:2.6, p = 0.002; OR: 1.8, p = 0.047 and OR: 1.0, p = 0.007 respectively), diabetes duration (≥5 years) and poor glycaemic control for microvascular complication (OR: 1.0, p = 0.031 and OR:2.0, p = 0.028). As a result, hypogonadism is frequent among diabetic males and poor glycaemic control may be an important contributing factor. Furthermore overt hypogonadism is an important cardiovascular risk marker. Therefore, ensuring eugonadism in diabetic patients may positively affect both glycaemic control and complications.

INTRODUCTION: Accessory pathways are commonly seen due to delamination of tricuspid valve leaflets. In addition to accessory pathways, an enlarged right atrium due to tricuspid regurgitation and incisional scars creates substrates for atrial re-entries and ectopic tachycardia. We sought to describe our experience with catheter ablation in children with Ebstein's anomaly. METHODS AND RESULTS: During the study period, of 89 patients diagnosed with Ebstein's anomaly, 26 (30.9%) of them who underwent 33 ablation procedures were included in the study. Accessory pathways were observed in the majority of procedures (n = 27), whereas atrial flutter was observed in five, atrioventricular nodal reentrant tachycardia in five, and atrial tachycardia in two procedures. Accessory pathways were commonly localised in the right posteroseptal (n = 10 patients), right posterolateral (n = 14 patients), septal (n = two patients), and left posteroseptal (n = one patient) areas. Multiple accessory pathways and coexistent arrhythmia were observed in six procedures. All ablation attempts related to the accessory pathways were successful, but recurrence was observed in five (19%) of the ablations. Ablation for atrial flutter was performed in five patients; two of them were ablated successfully. One of the atrial tachycardia cases was ablated successfully. CONCLUSIONS: Ablation in patients with Ebstein's anomaly is challenging, and due to nature of the disease, it is not a rare occasion in this group of patients. Ablation of accessory pathways has high success, but also relatively high recurrence rates, whereas ablation of atrial arrhythmias has lower success rates, especially in operated patients.
