Item Comparison of Surgical Techniques Used in Ventricular Septal Defect Closure(2023) Celik, Mehmet; Aygun, Fatih; Gunaydin, Asim Cagri; Gokdemir, Mahmut; Cindik, Nimet; 0000-0002-5018-0068; 36592069; AAT-2031-2021Introduction: We compared transatrial closure, tricuspid valve septal detachment, and tricuspid valve chordal detachment techniques for ventricular septal defect (VSD) closure. Methods: Patients who had VSD closure with three different techniques in our clinic between September 2016 and December 2020 were retrospectively reviewed. A total of 117 patients were included in the study. The patients were divided into three groups: group 1, classical transatrial closure; group 2, closure with tricuspid valve septal detachment; and group 3, closure with tricuspid valve chordal detachment. The groups were evaluated by serial transthoracic echocardiography (preoperative, postoperative 1st day, postoperative 1st month). Cardiac rhythm checks and recordings were performed. Results: No residual VSD was observed in early or late periods in any of the groups whose VSD closure was performed with the three different techniques. No severe tricuspid regurgitation (TR) was detected during the early and late postoperative periods of all operating procedures. When the groups were compared in terms of early/late TR after the operation (without TR+trace amount of TR and mild TR+moderate TR were compared), no statistically significant difference was found (P>0,05; P=0,969 and P>0,05; P=0,502). Conclusion: In this study, we found no statistically significant difference between three VSD closure techniques in terms of early TR, late TR, residual VSD, and permanent atrioventricular complete block during postoperative period. We hope that our results will be supported by the results of researches that are being made about this subject in large series.Item New Perspective On Fatigue In Hemodialysis Patients With Preserved Ejection Fraction: Diastolic Dysfunction Fatigue And Diastolic Dysfunction(2022) Akbay, Ertan; Akinci, Sinan; Coner, Ali; Adar, Adem; Genctoy, Gultekin; Demir, Ali Riza; https://orcid.org/0000-0002-9146-0621; https://orcid.org/0000-0001-5250-5404; AAD-5479-2021; AAD-5564-2021The relationship between diastolic dysfunction and fatigue in hemodialysis patients with preserved ejection fraction is unknown. In this context, the objective of this study is to assess fatigue using the relevant scales and to demonstrate its relationship with diastolic dysfunction. The patients who underwent hemodialysis were evaluated prospectively. Patients' fatigue was assessed using the Visual Analogue Scale to Evaluate Fatigue Severity (VAS-F). The echocardiographic works were performed as recommended in the American Society of Echocardiography guidelines. A total of 94 patients [mean age 64.7 +/- 13.5 years, 54 males (57.4%)] were included in the study. The median VAS-F score of these patients was 68.5 (33.25-91.25), and they were divided into two groups according to this value. Peak myocardial velocities during early diastole (e ') and tricuspid annular plane systolic excursion (TAPSE) values were found to be significantly lower in the group with high VAS-F scores, whereas the early diastolic flow velocities (E)/e ' ratio and pulmonary artery peak systolic pressures (PAP) were found to be significantly higher (p < 0.05, for all). E/e ' ratio (r 0.311, p 0.002) and PAP (r 0.281, p 0.006) values were found to be positively correlated with the VAS-F score, as opposed to the TAPSE (r - 0.257, p 0.012) and e ' (r - 0.303, p 0.003) values, which were found to be negatively correlated with the VAS-F score. High fatigue scores in hemodialysis patients may be associated with diastolic dysfunction. In addition, in our study, we determined the correlation of VAS-F score with E/e ' ratio, PAP and TAPSE.Item EVALUATION OF EPICARDIAL FAT AND CAROTID AND FEMORAL INTIMA-MEDIA THICKNESSES IN GERIATRIC PATIENTS WITH END-STAGE RENAL DISEASE(2020) Gunesli, Aylin; Yilmaz, Mustafa; Yalcin, Cigdem; Tekkarismaz, Nihan; Alkan, Ozlem; 0000-0002-2557-9579; 0000-0001-5483-8253; 0000-0001-7631-7395; S-6973-2016; AAM-4284-2021; AAD-9088-2021Introduction: Although atherosclerotic cardiovascular diseases and cardiovascular risks are known to increase in patients with end-stage renal disease, it is not clear whether these risks increase in the geriatric patient population as well. This study aims to evaluate these risks in geriatric patients with end-stage renal disease by evaluating epicardial fat and carotid and femoral intima-media thicknesses, known as markers, for subclinical atherosclerosis and cardiovascular risks. Materials and Methods: This cross-sectional study included 52 patients who started to receive chronic hemodialysis treatment after the age of 65 years (mean age 73.92 +/- 5.63) years with end-stage renal failure and 51 healthy volunteers (mean age: 74.49 +/- 4.63 years). Epicardial fat and carotid and femoral intima-media thicknesses were measured and compared between these groups. Results: Carotid intima-media and epicardial fat thicknesses were significantly higher in the patient group than in the control group (0.91 +/- 0.08 vs. 0.71 +/- 0.1 mm, p<0.001 and 0.84 +/- 0.17 vs. 0.75 +/- 0.17 cm, p=0.01, respectively). However, no significant difference was observed in femoral intima-media thickness between the two groups (0.58 +/- 0.07 vs. 0.56 +/- 0.97 mm, p=0.266). Correlation analysis revealed a significant positive correlation between the duration of dialysis and epicardial fat and carotid intima-media thicknesses (r=0.611, p<0.001 and r=0.337, p=0.015, respectively). Furthermore, regression analysis revealed a significant relationship between the duration of dialysis and carotid intima-media thickness (beta=0.657, p=0.001). Conclusion: Epicardial fat and carotid intima-media thicknesses increase in geriatric patients with end-stage renal disease but with no significant changes in femoral intima-media thickness, indirectly suggesting that subclinical atherosclerosis and cardiovascular risks are increased in these patients.Item Global evaluation of echocardiography in patients with COVID-19(2020) Dweck, Marc R.; Bularga, Anda; Hahn, Rebecca T.; Bing, Rong; Lee, Kuan Ken; Chapman, Andrew R.; White, Audrey; Di Salvo, Giovanni; Sade, Leyla Elif; Pearce, Keith; Newby, David E.; Popescu, Bogdan A.; Donal, Erwan; Cosyns, Bernard; Edvardsen, Thor; Mills, Nicholas L.; Haugaa, Kristina; 32556199Aims To describe the cardiac abnormalities in patients with COVID-19 and identify the characteristics of patients who would benefit most from echocardiography. Methods and results In a prospective international survey, we captured echocardiography findings in patients with presumed or confirmed COVID-19 between 3 and 20 April 2020. Patient characteristics, indications, findings, and impact of echocardiography on management were recorded. Multivariable logistic regression identified predictors of echocardiographic abnormalities. A total of 1216 patients [62 (52-71) years, 70% male] from 69 countries across six continents were included. Overall, 667 (55%) patients had an abnormal echocardiogram. Left and right ventricular abnormalities were reported in 479 (39%) and 397 (33%) patients, respectively, with evidence of new myocardial infarction in 36 (3%), myocarditis in 35 (3%), and takotsubo cardiomyopathy in 19 (2%). Severe cardiac disease (severe ventricular dysfunction or tamponade) was observed in 182 (15%) patients. In those without pre-existing cardiac disease (n = 901), the echocardiogram was abnormal in 46%, and 13% had severe disease. Independent predictors of left and right ventricular abnormalities were distinct, including elevated natriuretic peptides [adjusted odds ratio (OR) 2.96, 95% confidence interval (CI) 1.75-5.05) and cardiac troponin (OR 1.69, 95% CI 1.13-2.53) for the former, and severity of COVID-19 symptoms (OR 3.19, 95% CI 1.73-6.10) for the latter. Echocardiography changed management in 33% of patients. Conclusion In this global survey, cardiac abnormalities were observed in half of all COVID-19 patients undergoing echocardiography. Abnormalities were often unheralded or severe, and imaging changed management in one-third of patients.Item Subclinical myocardial dysfunction in liver transplant candidates determined using speckle-tracking imaging(2019) Inci, Saadet Demirtas; Sade, Leyla Elif; Altin, Cihan; Pirat, Bahar; Pamukcu, Hilal Erken; Yilmaz, Sabriye; Muderrisoglu, Haldun; 31802775Objective: There are various cardiovascular abnormalities in end-stage liver disease (ESLD). In these patients, left ventricular (LV) systolic function is normal at rest but deteriorates during stress. This deterioration may be due to subclinical myocardial dysfunction. This study evaluated global LV and right ventricular (RV) functions using 2-dimensional (2D) speckle tracking in patients with ESLD. Methods: Forty liver transplant candidates with ESLD and 26 healthy individuals were included in the study. All of the patients underwent conventional echocardiographic measurement. Longitudinal, circumferential, and radial strain measurements, as well as apical and parasternal short-axis image recordings were obtained. All 2D strain measurements were measured with offline analysis using velocity vector imaging (VVI) software. Results: In the apical 4- and 2-chamber measurements, the LV mean longitudinal strain was significantly lower in the patient group compared with that of the control group (-16.0 +/- 3.2% versus -17.6 +/- 2.2%, -16.7 +/- 3.3% versus -18.7 +/- 2.1 +/- 2.1 %; p=0.002, respectively). The LV mean circumferential strain did not differ between groups. The LV mean radial strain and RV longitudinal strain were significantly lower in the patient group (45.4 +/- 10.7 vs. 52.7 +/- 10.8%; p=0.01 and -19.2 +/- 3.5% versus -21.5 +/- 3.6%; p=0.03, respectively). Conclusions: Subclinical impairment of global LV and RV systolic functions was determined in liver transplantation candidates using VVI. This deterioration was detected in longitudinal and radial deformation rather than circumferential deformation mechanics, which is consistent with early-stage LV myocardial dysfunction.Item Evaluation of Polycystic Ovary Syndrome Patients with Strain Echocardiography(2015) Aslan, Gamze; Aslan, Recep Cagdas; Sade, Leyla Elif; Bal, Ugur; Onalan, Gogsen; Zeyneloglu, Hulusi Bulent; Kuscu, Esra; Muderrisoglu, HaldunObjectives: Polycystic Ovary Syndrome (PCOS) is characterized by several metabolic abnormalities that may lead to insulin resistance, diabetes, and atherosclerosis which are associated with chronic inflammatory processes and oxidative stress. Due to this fact PCOS patients are at increased risk of cardiovascular diseases. We used echocardiographic quantification tools to detect subclinical changes in myocardial functions. Materials and Methods: Echocardiographic, hormonal and metabolic measurements were performed in twenty-six women with PCOS and twenty-three healthy volunteers. The age of the attendants ranged between 20 and 31 years. PCOS was diagnosed by using the Rotterdam criteria. We compared the myocardial functions of PCOS patients without any cardiovascular symptoms with healthy volunteers by using strain echocardiography. Results: No differences were found between the two groups' strain, strain rate and myocardial velocity measurements. Conclusion: According to our study PCOS patients without any clinical cardiovascular symptoms have no impairment in myocardial functions. These results should be further confirmed in larger controlled studies.Item Rational and design of EuroCRT: an international observational study on multi-modality imaging and cardiac resynchronization therapy(2017) Sade, Elif; Donal, Erwan; Delgado, Victoria; Magne, Julien; Bucciarelli-Ducci, Chiara; Leclercq, Christophe; Cosyns, Bernard; Sitges, Marta; Edvardsen, Thor; Stankovic, Ivan; Agricola, Eustachio; Galderisi, Maurizio; Lancellotti, Patrizio; Hernandez, Alfredo; Plein, Sven; Muraru, Denisa; Schwammenthal, Ehud; Hindricks, Gerhard; Popescu, Bogdan A.; Habib, Gilbert; 28329299Aims Assessment of left ventricular (LV) volumes and ejection fraction (LVEF) with cardiac imaging is important in the selection of patients for cardiac resynchronization therapy (CRT). Several observational studies have explored the role of imaging-derived LV dyssynchrony parameters to predict the response to CRT, but have yielded inconsistent results, precluding the inclusion of imaging-derived LV dyssynchrony parameters in current guidelines for selection of patients for CRT. Methods The EuroCRT is a large European multicentre prospective observational study led by the European Association of Cardiovascular Imaging. We aim to explore if combing the value of cardiac magnetic resonance (CMR) and echocardiography could be beneficial for selecting heart failure patients for CRT in terms of improvement in long-term survival, clinical symptoms, LV function, and volumes. Speckle tracking echocardiography will be used to assess LV dyssynchrony and wasted cardiac work whereas myocardial scar will be assessed with late gadolinium contrast enhanced CMR. All data will be measured in core laboratories. The study will be conducted in European centres with known expertise in both CRT and multimodality cardiac imaging.Item Multimodality Imaging in Restrictive Cardiomyopathies: An EACVI expert consensus document In collaboration with the "Working Group on myocardial and pericardial diseases" of the European Society of Cardiology Endorsed by The Indian Academy of Echocardiography(2017) Sade, Leyla Elif; 0000-0003-3737-8595; 28510718; AAQ-7583-2021Restrictive cardiomyopathies (RCMs) are a diverse group of myocardial diseases with a wide range of aetiologies, including familial, genetic and acquired diseases and ranging from very rare to relatively frequent cardiac disorders. In all these diseases, imaging techniques play a central role. Advanced imaging techniques provide important novel data on the diagnostic and prognostic assessment of RCMs. This EACVI consensus document provides comprehensive information for the appropriateness of all non-invasive imaging techniques for the diagnosis, prognostic evaluation, and management of patients with RCM.Item Rationale and design of the EACVI AFib Echo Europe Registry for assessing relationships of echocardiographic parameters with clinical thrombo-embolic and bleeding risk profile in non-valvular atrial fibrillation(2018) Sade, Leyla Elif; Galderisi, Maurizio; Donal, Erwan; Magne, Julien; Lo Iudice, Francesco; Agricola, Eustachio; Cameli, Matteo; Schwammenthal, Ehud; Cardim, Nuno; Cosyns, Bernard; Hagendorff, Andreas; Neskovic, Alexandar N.; Luis Zamorano, Jose; Lancellotti, Patrizio; Habib, Gilbert; Edvardsen, Thor; Popescu, Bogdan A.; 0000-0003-3737-8595; 29474699; AAQ-7583-2021The European Society of Cardiology (ESC) guidelines for management of atrial fibrillation (AF) recommend the use of CHA(2)DS(2)VASc risk score for assessment of thromboembolic (TE) risk, whereas the stratification of bleeding risk should be obtained by HAS-Bleed to balance the most appropriate anticoagulation (OAC) therapy. However, men with CHA(2)DS(2)VASc score=1 and women with CHA(2)DS(2)VASc=2, who are at intermediate TE risk, represent a grey zone where guidelines do not provide a definite OAC indication. Accordingly, implementation of risk stratification with echocardiography could be extremely useful. Both prospective and cross-sectional studies on transthoracic echocardiography (TTE) prediction of TE events and studies utilizing transoesophageal echocardiographic parameters as surrogate markers of TE events makes sustainable the hypothesis that echocardiography could improve TE prediction in non-valvular AF. Moreover, considering the close association of AF and stroke, all echo-Doppler parameters that have shown to predict AF onset and recurrence could be useful also to predict TE events in this clinical setting. Accordingly, EACVI AFib Echo Europe Registry has been designed as an observational, cross-sectional study, with the aim of evaluating: (i) left atrial (LA) size and function together with left ventricular geometry, systolic and diastolic functions in paroxysmal, persistent, and permanent AF; (ii) relationships of structural/ functional parameters with clinical TE and bleeding risk profile. By the AFib Echo Europe Registry, we expect to collect data on echocardiographic phenotype of patients with AF. The large data set accumulated will be useful to test the level of agreement of different echocardiographic measurements with the available risk scores.Item Evaluation of right ventricular function in operated tetralogy of Fallot patients with tissue Doppler imaging before and after pulmonary valve replacement(2018) Varan, Birgul; Gursu, Hazim Alper; Erdogan, Ilkay; Ozkan, Murat; 32082764Background: This study aims to investigate the efficacy of tissue Doppler echocardiography for the diagnosis of right ventricular dysfunction and for the evaluation of the response to pulmonary valve replacement. Methods: Between December 2008 and December 2010, a total of 15 patients (8 males, 7 females; mean age: 14.5 +/- 4.5 years; range, 7 to 22 years) with pulmonary valve insufficiency in the follow-up of total correction of tetralogy of Fallot who underwent pulmonary valve replacement were included in the study. Echocardiographic imaging was performed before and one, three, and six months after replacement. Using pulse wave Doppler, early diastolic E and late diastolic A waves were measured in the flow velocity curve of tricuspid valve. Tissue Doppler measurements were made from the basal segment of right ventricular free wall and interventricular septum. S, e, and a myocardial velocities, isometric contraction time, isovolumetric relaxation time and ejection time were measured. Myocardial performance index was calculated for each patient. Results: In pre-pulmonary valve replacement phase, s, e, a velocities and ejection time were lower in the interventricular septum compared to the basal segment of right ventricular free wall, while isometric contraction time, isovolumetric relaxation time and myocardial performance index values were higher. In the first post-replacement month, there was a significant decrease in the s value of interventricular septum, compared to pre-pulmonary valve replacement period; isometric contraction time decreased and myocardial performance index increased in the first post-pulmonary valve replacement month in the free wall of right ventricle, while isovolumetric relaxation time decreased in the postoperative third month, and s velocity, isometric contraction time and myocardial performance index increased in the postoperative sixth month. Pre-pulmonary valve replacement tissue Doppler values at the septum showed that myocardial systolic and diastolic dysfunction developed earlier than the basal segment of right ventricular free wall. This result showed that right ventricular recovery was not complete in the sixth post-pulmonary valve replacement month. Conclusion: Tissue Doppler can show right ventricular dysfunction before replacement, but it may be insufficient to visualize right ventricular recovery until six months after treatment.
